My Silicon Motion-based USB Docking Station or USB Video Adapter Is Not Working As Expected
When a Plugable Silicon Motion device is not working as expected with a Windows system, the best practice is to disconnect the device from the host system (and remove it's external power source, if it has one) and perform a manual installation of the latest version we recommend of the required Silicon Motion software driver to help ensure both are in a good state. To do so, please follow these steps:
- Disconnect the Plugable Silicon Motion USB docking station or video adapter from the host system. If the product you are using has an external power adapter (for example a USB docking station), please also disconnect the power adapter from the product so that the unit resets. Please keep everything disconnected until prompted
- Uninstall any and all software with 'Silicon Motion' in the title that is present from within the Control Panel > Programs and Features (Apps and Features in Windows 10). If an entry is not listed in the Programs and Features application, the driver was likely installed automatically by Windows Update. Please then move on to the next step of installing the latest recommended driver
- Once the uninstallation has completed running, restart the host system (even if not prompted to)
- Download and install the latest version (that we recommend) of the Silicon Motion software driver
- If you disconnected the power adapter from your product in step one, please reconnect it so the device powers on, then reconnect the product to the host system. If the product is still not working as expected, please restart the host system one more time.
If, after having completed this process, your Plugable Silicon Motion device is still not working as expected, please reach out to us directly via support@plugable.com with the output of our PlugDebug diagnostic utility and we will be happy to help
Which USB-C port on this product can be used to connect it to my computer?
For products which have multiple USB-C ports, normally only one port is capable of connecting the product to a computer. USB-C ports capable of connecting the product to a computer are sometimes called “Host” or “Upstream” ports.
On Plugable products with multiple USB-C ports, the dedicated port for connecting to the computer will be marked with a small laptop icon or the words “To host”.
A product may not be able to function if it is connected to a computer through a different USB-C port. These ports are also known as “Hub" or “Downstream” ports.

USB Port Types
USB-A
pietz, CC BY-SA 3.0 , via Wikimedia Commons
This is the standard USB connection that most computers offered prior to the introduction of USB Type-C (USB-C). Even after the introduction of USB Type-C, this is still quite common.
It can provide data transfer rates up to the USB 3.1 Gen 2 (10 gbps) specification depending on the host and device, but does not directly support video in the way that USB-C Alternate Mode does. This limitation makes DisplayLink USB graphics adapters and docking stations ideal on systems that do not have USB-C, or in instances where more displays are needed beyond available video outputs of a PC.
USB-B

This type of connection comes in a couple different styles depending on whether USB 3.0 and higher transfer rates are supported (bottom graphic). Usually this type of connection is used to plug into USB devices that do not have a fixed cable connected, such as USB docking stations, USB hubs, printers, and others.
USB Mini-B
Fred the Oyster, CC BY-SA 4.0 , via Wikimedia Commons
One of the first connectors for charging a smartphone, wireless game controller (such as the Sixaxis and DualShock 3), and other small devices such as external hard drives. Not commonly used today, but is still used in some cases. Most devices using USB Mini B are using USB 2.0, though a USB 3.0 variant does exist. This specification also added USB On-The-Go (OTG) functionality, though it is more commonly implemented with Micro USB.
USB Micro-B
Fred the Oyster, CC BY-SA 4.0, via Wikimedia Commons
IngenieroLoco, CC BY-SA 4.0 , via Wikimedia Commons
A smaller connector that serves many of the same uses as the Mini B connector, with added optional features such as Mobile High-Definition Link (MHL) to allow devices like smartphones to output video to larger displays without requiring a dedicated port for video output.
The larger variant of USB-B is most commonly used for external hard drives for higher 5Gbps transfer rates.
USB-C, Thunderbolt™ 3, and Thunderbolt™ 4
Niridya , CC0, via Wikimedia Commons
The most recent USB connection, USB Type-C (USB-C), represents a major change in what USB can do. The connector is smaller, can be connected in two orientations, is able to carry substantially more power and data, and can directly carry video signals of multiple types (HDMI, DisplayPort, etc.) Intel has also adapted the USB-C connector for use with Thunderbolt 3 and Thunderbolt 4.
It is important to note that while all Thunderbolt 3 and Thunderbolt 4 connections are USB-C, not all USB-C connections can be used with Thunderbolt 3 or Thunderbolt 4 devices.

Can I Connect a DisplayPort (DP) Monitor to the HDMI Port on This Device Using an Adapter or Cable?
No. Most DisplayPort to HDMI cables and adapters are one-way adapters from a DisplayPort Source (computer or docking station) to a HDMI Sink (television, computer monitor, or projector). These cables do not work in reverse.
DisplayPort uses packet-based data transmission, breaking the video stream into individual packets of data allows for longer cable runs, use in both copper and fiber-optic cables, and allows for higher bandwidth than other video formats. It is relatively easy to convert from DisplayPort to HDMI (computers with HDMI output ports already do this internally) and dual-mode DisplayPort outputs have built-in adapters to output a HDMI signal for use with passive DisplayPort to HDMI adapters.
HDMI uses a video signal, similar to DVI, this requires more power to operate at the same cable lengths as DisplayPort and requires significantly more processing power to create DisplayPort packet-based data.
Externally powered HDMI to DisplayPort adapters do exist, these generally have a USB or small barrel plug for power, and can convert from a HDMI Source to DisplayPort Sink. In most cases they have reduced resolution or refresh rates compared to modern signal sources and can introduce delay in the data connection between the display and computer potentially causing reduced connectivity or display performance problems.
We do not currently recommend using HDMI to DisplayPort adapter with our docking stations. In our testing they have been unreliable compared to a native DisplayPort connection. Many of our newer docking stations include both HDMI and DisplayPort outputs to reduce the need for additional adapters or adapter cables.
Understanding and Troubleshooting Network Performance
Computer networking is a complex topic. In this article, we'll be taking a deep dive on the nuances of network performance for those who need some additional explanation while striving to be concise, and to educate users of various experience levels relating computer hardware and computer networking.
If you just need to know how to perform a network performance test/benchmark, jump down to configuring iPerf.
Core Network Concepts
LAN vs WAN
With regards to network performance, it is crucial to first separate whether an issue is with Wide Area Network (WAN) performance, or if the issue is with Local Area Network (LAN) performance.
Your LAN is essentially the network inside your home or business. Many homes use a combination modem/router device provided by their Internet Service Provider (ISP). In some cases, especially in businesses, you may have a separate modem and router, along with other equipment connecting to the router such as a network switch.
Your modem, and the connection it establishes to your ISP—whether through coaxial cable, fiber, phone lines, or long-range wireless—essentially marks the point between the WAN and the LAN. The connection your modem makes to your ISP is the WAN, and any devices you connect through your router behind that modem belong to the LAN.
Link Rate
Almost every type of connection your computer makes to any piece of hardware will have a link rate of some kind. The link rate establishes how fast data can possibly be transferred across any given connection, but it does not guarantee how fast the hardware on either end of the connection will actually transfer data.
The concept of link rates, and their related bottlenecks, is likely best conveyed by giving an example of what connections might be involved in transferring a file from one computer on your LAN to another.
- 800Mbps—The file source is a USB 3.0 thumb drive capable of 100MB/s (800Mbps) read/write.
- 480Mbps—The USB 3.0 thumb drive is plugged into a USB 2.0 port on the PC, which has a maximum throughput of 480Mbps
- 1000Mbps—PC1's Ethernet connection establishes 1Gbps (1000Mbps) link to the router via Ethernet
- 300Mbps—The router connects to a second PC (we'll refer to this as PC2) via Wi-Fi, and it has established a 300Mbps link to the Wi-Fi adapter on PC2
- 480Mbps—The Wi-Fi adapter on PC2 is connected via a USB 2.0 port. The link rate of the USB connection to PC2 is at 480Mbps
- 6000Mbps—PC2 is going to store the file on an internal hard drive with a link rate of 6Gbps
- 1600Mbps—File Destination: SATA hard drive capable of 200MB/s (1600Mbps) read/write.
Following this chain, we see that 300Mbps is the slowest link rate established. This means that, regardless of the link rates established elsewhere, the absolute maximum the data can possibly be transferred is 300Mbps.
if we were to change the Wi-Fi connection to a wired Ethernet connection capable of 1Gbps, our performance bottleneck would then become the USB 2.0 connection to the USB drive where the file is stored.
Ports and Interfaces
Interfaces
A network interface represents connections, whether wired or wireless, that are made to form a network between devices.
Ports
Some may refer to physical hardware connections as "ports". For the purposes of networking, ports are logical constructs that can also be referred to as "network ports". Each network interface has 65,535 of these logical ports. Each port on a network interface is a separate data connection.
Benchmarking Network Adapter Performance
To properly benchmark network adapter performance, we need to:
- Use a simple LAN configuration
- Eliminate bottlenecks, especially link rate bottlenecks
Websites like speedtest.net, fast.com, and other performance tools in your web browser are going to use your WAN connection, and are not appropriate for determining if a network adapter is working well.
Transferring files from one computer to another on your LAN is typically not the best way to benchmark a network adapter. File transfers are bottlenecked by a number of things, including performance limitations of the disk the data is on, and often times a lack of establishing parallel network connections to perform the task.
One of the most accurate ways to benchmark network performance on a LAN is by using iPerf . To more effectively benchmark network adapter performance, it is best to establish a point-to-point connection between two PCs, rather than connecting through a router or switch.
Configuring iPerf
To test a connection using iPerf, you'll need at least two network interfaces, and preferably two computers. You'll also need to know the IP (Internet Protocol) address assigned to each network interface . One network interface will function as an iPerf server, and the other network interface will function as an iPerf client. Lastly, you'll need to download the version of iPerf 3.x that's appropriate for your computer's operating system and extract/install it .
Windows
- Make sure the drivers for both network interfaces involved in the test are using up-to-date drivers. Drivers for Plugable products can be found here.
- Download and extract iPerf for Windows
- Open Command Prompt
- Press Windows Key + R or + R, then enter
cmdin the window that appears - Search the Start Menu for
Command Prompt, and open it
- Press Windows Key + R or + R, then enter
- Navigate Command Prompt to the directory the directory where iPerf is located
- The
cdcommand is for 'change directory'- If you have a folder named 'iperf' on your Windows desktop, you can reach it in command prompt with the command
cd %USERPROFILE%\Desktop\iperf
- If you have a folder named 'iperf' on your Windows desktop, you can reach it in command prompt with the command
- The
- Run iperf in server mode via Command Prompt
iperf3.exe -s
macOS
- Usually it is best to install iperf on macOS using brew in Terminal
- Make sure the drivers for both network interfaces involved in the test are using up-to-date drivers
- Open Terminal
- Run iPerf in server mode
iperf3 -s
Linux
- Usually it is best to install iperf using the package manager in your Linux distro. For example, in Ubuntu, use
apt: sudo apt install iperf3
- Make sure the drivers for both network interfaces involved in the test are using up-to-date Drivers
- Open Terminal
- Run iPerf in server mode
iperf3 -s
Next, you'll need to run iPerf in client mode, targeting the IP address of the server/interface where iPerf is running in server mode. Additionally, we'll run the test for 30 seconds using -t 30 and with four parallel connections using -P 4. Running 4 parallel connections is optimal for saturating a network link.
Windows
- Open Command Prompt
- Press Windows Key + R or + R, then enter
cmdin the window that appears - Search the Start Menu for
Command Prompt, and open it
- Press Windows Key + R or + R, then enter
- Navigate Command Prompt to the directory the directory where iPerf is located
- The
cdcommand is for 'change directory'- If you have a folder named 'iperf' on your Windows desktop, you can reach it in command prompt with the command
cd %USERPROFILE%\Desktop\iperf
- If you have a folder named 'iperf' on your Windows desktop, you can reach it in command prompt with the command
- The
- Run iperf in client mode via Command Prompt (replace 192.168.0.200 with the IP address of the server/interface where iPerf is running in server mode)
iperf3.exe -c 192.168.0.200 -t 30 -P 4
macOS / Linux
- Open Terminal
- Run iPerf in client mode (replace 192.168.0.200 with the IP address of the server/interface where iPerf is running in server mode)
iperf3 -c 192.168.0.200 -t 30 -P 4
iPerf should start performing a network performance test. If the test fails to start, make sure that iPerf is not being blocked by your PC's/Mac's firewall.
Why iPerf is Ideal for Benchmarking
Unlike a file transfer, iPerf runs in memory on the PC and generates data to send using the CPU directly. This alleviates potential bottlenecks generated by storage devices, and allows you to explicitly control how many parallel connections are being used to transfer data rather than being unsure if parallel network connections are being used by other means.
Conclusion
There's a lot more to networking that isn't covered in this article, but we hope this helps explain enough to get an accurate measure of your network performance.

My Docking Station/Adapter Works Well With My Windows Laptop, but When I Close the Lid the Displays and Laptop Turn Off or Sleep. How Do I Fix This?
Most Windows notebook computers power management settings will default to putting the computer to sleep with the lid closed, regardless of any external displays, keyboard, or mouse connected to the computer. If this is happening but you would prefer the system to remain active with the lid closed utilizing the external display or displays, these settings can be changed by performing the following:
For Windows 10:
- Start by right-clicking on the Start button and select Power Options from the menu.
- From the right side of the Power Options settings page, select the blue link for Additional power settings
- From the choices present on the left-hand side of the Power Options window, please click on Choose what closing the lid does
- Make sure the setting for When I close the lid under the Plugged In column is set to Do Nothing
- Click the Save Changes button and restart the system (making sure that the laptop’s power adapter is also connected) and test the behavior again.
For Windows 11:
- Start by right-clicking on the Start button and select Power Options from the menu.
- In the upper left corner of the settings window, in the search box, type "lid" then select Change what closing the lid does from the search results
- Make sure the setting for When I close the lid under the Plugged In column is set to Do Nothing
- Click the Save Changes button to apply the new settings.
Closing the lid should no longer put the computer into sleep mode when an external display and power source is connected, instead one of the external displays should now become the Primary display with the desktop icons instead of the laptop's built-in display.
The lid may still need to be opened to perform the following tasks:
- To power on the computer from a fully powered off state
- To log into the computer if logged out or if the computer is restarted with the lid closed
- To wake the computer from a deep sleep state ( hibernation, or Windows hybrid sleep states )
My Windows Laptop Will Not Boot Properly When My Docking Station Is Connected
If your Windows laptop will not boot properly when a docking station is connected to the laptop, most often the cause is an external device connected to the docking station (for example an external USB storage drive) as opposed to the dock itself.
If you are affected by this condition, please follow these steps in order to isolate the behavior further:
- Disconnect all USB devices from the docking station and put them aside for the moment.
- Disconnect any displays connected to the dock's video outputs.
- Disconnect any audio devices connected to the dock's audio ports (if present).
- Disconnect the Ethernet network cable from the dock's Ethernet port (if present).
- The only remaining connections should be the dock's power adapter cable and the USB cable used to connect it to the laptop. No other external devices should be connected to the dock.
- While in this state, reboot the laptop to test the behavior.
- Assuming the laptop boots as expected, please reconnect each device back to the dock one at a time and reboot after each one to test the behavior again. Please reconnect the displays first, then the audio devices, then the Ethernet cable. Please reconnect any USB devices to the dock last, again rebooting after each one is added to test the behavior.
In our experience helping others, the most common cause of this behavior is an external USB storage drive connected to one of the dock's USB ports. In some cases, a laptop may try to boot from an external storage drive by mistake as opposed to the laptop's built-in storage drive. Since most external USB storage drives are not 'bootable', this can interrupt the boot process.
If this behavior occurs, the most common way to mitigate the behavior is to access the laptop's System BIOS (also known as UEFI firmware) to change the 'boot order' settings to ensure that the laptop's internal storage drive is the first boot option. Doing so helps ensure that the laptop will not try to boot from an external USB storage device.
Every laptop system is different, so the best resource for accessing the System BIOS and changing the settings is the manual for the laptop provided by the laptop manufacturer.
Why Does Image Quality With My Silicon Motion Graphics Adapter or Docking Station Not Seem As Crisp As My Laptop Screen or Directly Connected External Monitor?
Silicon Motion technology uses the Silicon Motion software driver on Windows and Silicon Motion InstantView application on macOS to generate a "virtual desktop" image that is sent over a USB connection to the adapter. These pixels are rendered by the Silicon Motion chip within the adapter to then send a video image to the connected monitors.
Because of the amount of data being sent the software driver must compress the data being sent so it can pass through efficiently over USB connections. This is why some images may not appear as "crisp" using a Silicon Motion adapter or docking station.
In our testing, Red colors are primarily affected where they can appear pixelated or blurry when viewed closely.
Blue Light Reduction Applications Are Not Working While Connected to my Silicon Motion USB Dock or Adapter
The Silicon Motion driver does not currently support this type of color adjustment. As a result, applications like f.lux, Night Shift or Night Light will not affect displays connected to a Silicon Motion-based docking station or video adapter.
I Can't Use My Intel, NVIDIA, or AMD/ATI Graphics Utility to Manage the Monitors Connected to My Silicon Motion-Based Docking Station/Graphics Adapter. Why?
The graphical software utilities provided by Intel, NVIDIA and AMD/ATI are designed to only recognize and work with graphics adapters made by their respective manufacturers. As a result, they will not recognize USB-attached displays connected to a Silicon Motion-based docking station or graphics adapter.
It is recommended to use the facilities built-in to Windows to manage the connected displays. These would be the ‘Display Settings’ application on Windows 10 and ‘Screen Resolution’ application on Windows 8.1 and 7. Both of these applications are available by right-clicking on empty space within the Windows desktop and selecting the appropriate choice from the context menu that appears.
Why Doesn't the "Display Color Calibration" Tool in Windows Affect the Display(s) Attached to My Silicon Motion-Based Docking Station/Video Adapter?
The Silicon Motion driver does not support color calibration functionality of any kind. Most monitors have built-in controls that can be used to adjust the characteristics of the display, though we realize this approach may not be ideal in all cases. For environments that necessitate near-perfect color reproduction and display calibration capabilities via software, a dedicated graphics card is recommended.
Are Plugable USB Video Adapters or Docking Stations Based on Silicon Motion Technology Compatible With Touchscreens?
Touchscreens that do not require drivers and use the host’s operating system’s built-in USB Human Interface drivers (HID) to record touch inputs can be made to work with our products, however Plugable does not provide support for doing so due the complexity of multi-monitor touch screen setups.
If I Add a Silicon Motion-Based Docking Station or Graphics Adapter to My System, Will That Prevent My System’s Built-In Video Outputs From Working?
No, the Silicon Motion device's presence on your system will not preclude the use of any of your system’s built-in video outputs.
Can I Adjust the Brightness of a Display Connected to My Silicon Motion-Based Docking Station or Video Adapter via the Windows ‘Display Settings’ Application?
Windows does not have the ability to adjust the brightness of a display connected using Silicon Motion technology. We recommend making use of the display’s internal on-screen menu options in order to adjust the display's brightness.
Applications That Use OpenGL Such As Google Sketchup or Google Earth Do Not Work As Expected When Connected to a Silicon Motion-Based Graphics Adapter or Docking Station
Graphics adapters and docking stations based on Silicon Motion USB video technology are in essence a 'virtual' graphics adapter that relies on the host laptop's CPU and internal physical graphics processing unit (aka as GPU) to generate the information shown on the Silicon Motion-attached displays.
In rare instances, Windows applications that use a technology known as OpenGL to draw the image shown on the display will attempt to direct OpenGL related tasks to the Silicon Motion-based virtual graphics adapter, and not to the 'real'/'physical' GPU within the laptop.
Since the adapter or dock is not a physical GPU that supports OpenGL, this can sometimes cause applications that make use of OpenGL (such as Google Earth or AutoCAD) to not work as expected or result in various types of error messages.
The true root cause of this behavior can vary, and ultimately lies outside of the adapter, docking station or its associated Silicon Motion driver. In some cases the root cause lies within the Windows driver for the host system's physical GPU and in rarer cases within the Windows operating system itself.
In some cases updating either the driver for the system's internal GPU or updating Windows itself (when Microsoft provides such updates) can help, however that is unfortunately not always the case.
If updating those components does not help, in most cases there are two possible workarounds.
The first is to configure Windows to have the ‘Main’ display set to a display directly connected to the host system's built-in internal GPU, whether that is an internal laptop display or another external display connected to one of the system's built-in video outputs (a quick guide to doing so is here -> https://youtu.be/7nnKztRZXsw).
If the first option does not prove a suitable workaround, the second option is to boot the system without the adapter or dock connected, launching the affected application, and then connecting the adapter or dock may also help.

Can I Connect My High Refresh Rate Monitor (e.g. 120Hz, 144Hz) to a Plugable Dock?
Most Plugable docks do not officially support monitors over 60Hz including 120Hz or 144Hz refresh rate unless otherwise specified on the Plugable product page or listing.
DisplayLink USB Graphics technology and Silicon Motion based docking stations and graphics adapters, like our USB 3.0 dual display and USB Type-C triple display docking stations, are limited to 60Hz fresh rate by the USB graphics controller hardware.
USB Type-C DisplayPort Alternate Mode docking station and ports on our USB Type-C Triple Display Docking Stations can support higher refresh rates, but may be limited by the computer's capability and available bandwidth to the docking station. Additionally, when paired with DisplayLink or Silicon Motion USB graphics, having displays at different refresh rates may reduce overall system performance. Due to this we normally recommend limiting all connected displays to 60Hz refresh rate when using DisplayLink and Silicon Motion graphics technology with directly connected, or USB Type-C DisplayPort Alternate Mode controlled displays.
Monitors with refresh rates higher then 60Hz may be connected to a docking station operating at up to 60Hz, or connected directly on the computer's HDMI or DisplayPort to ensure the display is powered by the system's native GPU.
Do Plugable products support the Apple SuperDrive?

Can I leave my notebook computer connected to a charging dock overnight, or should I discharge and recharge the notebook battery regularly?
We are often asked if it is okay to leave a notebook computer connected to one of our USB-C docking stations with Power Delivery for extended periods of time. The short answer is yes, it is no different from leaving the laptop connected to the manufacturer's original USB-C power supply for the same time. The long answer is yes for modern laptops, and maybe for older (1990s-early 2000s laptops) and involves going into the different battery technologies used in consumer electronics devices.
Another common question is if it is possible to use the docking station but to disable powering and charging the computer. When a modern notebook computer runs on battery power it will often set the system to a reduced power state which may impact performance, or connected devices and we recommend always powering the computer when using a desktop docking station. For all of our docking stations that provide power to the host computer this will not affect the lifespan of the computer's battery.
Modern Laptop Batteries: Lithium-Ion
Lithium-ion (li-ion) batteries are found in a wide range of consumer electronics from notebook computers and cell phones, to electric cars, power tools, and wearable electronics like wireless earbuds. Li-ion offers fast charging, high-current discharging, fairly long service live compared to other rechargeable battery technologies and are relatively inexpensive.
The life-span of a rechargeable battery depends on many factors including age, temperature history, charging patterns, the chemical composition of the specific battery, and usage. For example batteries stored at 100% charge will degrade faster than batteries stored at 50% charge, this is why most consumer electronics devices arrive from the manufacturer with between 25% to 75% charge.
Lithium-ion batteries are consumable components, however in most modern computers, cell phones, and tablets these are not user serviceable components. To help maintain the battery all modern computers and most consumer electronics will include battery charge and protection circuits. These can be fairly simple, charging up the battery at preset rates depending on the charge level to help maintain the battery life, or complex software controlled charging that monitors battery temperature, voltage and current draw to maintain the fastest charging while maintaining the battery longevity.
Modern notebook computers can be left connected to the original power cable or a docking station with charging capability for extended periods, and do not benefit from regular discharge/recharge cycles. Our docking stations with charging capability rely on USB Type-C Power Delivery to power and charge compatible computers. USB Type-C Power Delivery is a negotiated charging protocol between the host computer and the docking station or USB Type-C power supply, this allows the computer to draw only the power it requires, and even select the best voltage level for powering the computer. In combination with a computer's built-in battery charging controller the computer is capable of maintaining the battery's optimal state even when left connected to a power source for an extended period of time.
Legacy Laptop Batteries: NiCad and NiMH
Older laptops, from the 1990s and some early 2000s, as well as some consumer electronics, and most rechargeable AA or AAA battery replacements use Nickel-Cadmium (NiCad) or Nickel-Metal Hydride (NiMH) batteries. These batteries are slower to charge and discharge than li-ion batteries, and require very simple charge controllers, and in some cases can even be trickle-charged ( very low-current continuous charging ) if desired.
These batteries generally don't have smart charging controllers and to prolong the life of the battery required "training" or fully discharging and recharging the battery every so often. Many laptop manufacturers recommended fully charging and discharging a new laptop 2-3 times to train the battery, this is not necessary with modern laptops.
Conclusion
Modern notebook batteries are managed by the computer's built-in battery charging circuit, and require little to no user intervention to maintain optimal battery health. It does not harm the battery to leave the computer connected to an external power supply, so long as the computer is being used regularly. If the computer is to be stored for a prolonged period then discharging the battery to between 50-75% can help to maintain the battery life.
Batteries are consumable components and degrade over time, however modern notebook computers can extend the battery life generally to meet or exceed the life of the computer's other electronic components.
Understanding how adaptive/optimized charging methods have an impact on your smartphone's battery life, performance, and longevity.
With most modern smartphones you may have likely noticed a notification message while charging your phone indicating that your phone has entered "Optimized Battery Charging", this is how Apple refers to its smart charging messaging. With Android devices they will also show this notification message while charging although they refer to it "Adaptive Charging". Through these intelligent charging methods your phone will artificially reduce its charging speeds so that in the long run it will lengthen its overall battery life.
When setting up a new smart phone it may take a few weeks of machine learning to recognize your usage behavior and charging habits. Batteries go through wear and tear to which the more charge cycles it goes through the less healthier the overall battery becomes leading to it holding a lesser charge and other issues.
Your phone will alert you with a notification when it enters into a battery preserving charging state. At night you may notice your phone charging significantly slower along with a message saying “Battery full by 7:00 AM”. Even though it has the ability to fully charge in a much shorter time. If you set an alarm for an even earlier time your phone can adjust to finish charging at your alarm time. This is your phone prolonging the time it takes to charge to 100% in order to preserve battery health.
The reason why your phone will artificially slow its charging rate is to spend less time at 100% battery, and the less time your phone spends at 100% the more it helps with your overall battery health.
It is possible to disable Optimized/Adaptive Charging in your device's battery and charging settings although it is ideal for the majority of users to leave this setting enabled.
Understanding Heat Generation in Electronics
It's not uncommon for users to notice a certain level of heat generation from electronics and by extension, Plugable products during operation. In this knowledge base article, we'll explore the reasons behind this heat generation and why it is considered a normal experience within reasonable limits.
Electronics, by their nature, generate heat during operation. This is primarily a result of the electrical current flowing through various components, such as integrated circuits, transistors, and other electronic elements. As Plugable products are designed to efficiently process and transfer data (among other functionality), some level of heat generation is inherent.
Factors Influencing Heat Generation:
- Power Consumption: The power consumption of a device directly influences the amount of heat it generates. Higher power usage, especially during data transfer or charging processes, can lead to increased heat.
- Enclosure Design: The design of the product's enclosure and its ability to dissipate heat play a crucial role. Adequate ventilation and heat sinks are often incorporated to manage and disperse generated heat effectively. This is evident in our TBT3-UDZ and TBT4-UDZ designs. The metal case in these docks are designed to function as a heatsink with thermal pads placed throughout the enclosure. This allows heat dissipation from inside to the outside, but will also make it feel as if the device is “too hot”.
- Ambient Temperature: The external environment may also play a role. Higher ambient temperatures can contribute to increased perceived heat from the product. This means that summer temperatures may increase the heat generation of not just Plugable products, but many other electronic devices.
Normal Heat Levels: While it is normal for electronic devices to generate heat, Plugable products are engineered to operate within safe temperature ranges. We conduct rigorous testing to ensure that the heat generated during normal operation falls within industry-standard safety parameters. While not all products are or need to be UL certified, we try to go by UL guidelines for thermal readings. The UL threshold is 77C/170.6F, and we aim for around 71C/160F.
Tips for Users:
- Ventilation: Ensure that Plugable products have sufficient ventilation around them. Avoid placing them in enclosed spaces where heat dissipation may be impeded.
- Usage Patterns: Intensive tasks such as high-speed data transfer or charging multiple devices simultaneously may result in increased heat generation. This is generally normal but may be more noticeable in such scenarios.
- Accessories: A number of our devices will allow for the connection of USB accessories and as such, these will require power. If too many “power-hungry” devices are connected, this will cause the device to run much hotter than expected. Be sure to keep in mind the power limits of your dock/device.
In conclusion, experiencing heat from Plugable products is a normal aspect of their operation. Users can rest assured that we prioritize the safety and efficiency of our devices. By understanding the factors influencing heat generation and following simple usage guidelines, users can make the most of their Plugable products while ensuring a reliable and efficient user experience.
macOS InstantView and "Screen Recording" Troubleshooting
If you have installed your Silicon Motion-enabled docking station or graphics adapter and downloaded the Silicon Motion software, but see that no displays are working properly, you may need to enable “Screen Recording”. In this guide, we will go over a short list of steps to enable this permission, and get your Silicon Motion device up and running!
As of macOS Catalina (version 10.15), Silicon Motion drivers that are installed require that the “Screen Recording” permission be granted by the user. While this permission, when used in conjunction with Silicon Motion, is not recording in a traditional sense, it does allow the software to access the pixels it needs to render images (mirrored or extended). It then sends these pixels over USB from the computer to the display connected to your Silicon Motion device.
When on your desktop you will see a purple screen icon, this message will appear saying that "macOS InstantView is capturing your screen". No sort of video storage or screen recording is being done by macOS InstantView, it's simply capturing the screen to render images for the additional monitors.
Note: It does not capture or send any data.
When your Mac is on the lock screen, in the menu bar it will show "Your Screen is being observed". This message is simply implying that the macOS InstantView is running in the background.
In the macOS menu bar you will see a Purple square with a person icon, if you select this it will show a message saying "Currently Sharing" this is the macOS InstantView software using the screen sharing API to enable your extended display. There is no recording or sharing of your monitor screen, this is just a generic message that macOS uses when the screen sharing API is being used.
During the installation process for the Silicon Motion drivers, you will be requested to allow “Screen Recording” for macOS InstantView. Additionally, you may see a notification during the macOS InstantView installation process. However, we understand sometimes these may get lost in a sea of information and other notifications.
How do I know if the Screen Recording permission hasn’t been set? Reference the image below to check in your “Privacy & Security” settings
If you have not enabled “Screen Recording”, please follow these few instructions to enable it.
- Click on the Apple icon (defaults to the top left corner of your screen) and select “System Preferences”.
- Navigate to and click “Security & Privacy”.
- In this window, select “Privacy”.
- A list will be presented, scroll until you find “Screen Recording” and click on it.
- Displayed on the bottom left, there is a lock icon, click on this to make changes.
- If prompted, login using your computer credentials to make changes.
- Check the box next to macOS InstantView.
- You will be promoted to “Quit & Reopen”, click this button.
- Click on the lock icon once more to save your changes.
Note: Some of these steps may vary slightly based on your macOS version.
You should now be able to see your displays on your docking station or adapter. If you have completed the above steps successfully and still do not see your displays, please be sure to reach out to our support team at support@plugable.com.

What is Alt Mode, and how does it work?
USB-C is a truly versatile connection that supports a range of functions, including power delivery, data transfer, and video. Alt Mode leverages this versatility by repurposing high-speed data pins to enable alternative video data protocols. Many of our docking stations support this protocol, but there is a catch! To take advantage of this feature, your host system must support Alt Mode via the host USB-C port and controller. If the host system and device support Alt Mode, the USB-C ports automatically switch from its default data protocol to the required Alt Mode protocol for video.
How do I determine if my system supports Alt Mode?
Reviewing your manufacturer's system specifications or user manual is the easiest way to determine if your system supports Alt Mode via the USB-C port, but unfortunately, it’s not always consistent or straightforward. Below, we have included examples of how some system manufacturers mention the capabilities of the USB-C ports on their laptops. This information will usually be included in the user manuals or system specification sheets.
Please note that mention of DisplayPort or DP 1.2, 1,4, and 2.1 indicates Alt Mode support.
Lenovo
HP
Dell
Additionally, some manufacturers, but not all, will also include a DP symbol next to the port to illustrate its ability to support video. If your USB-C port is unmarked, check your user manual or consult the system specifications.
What about Thunderbolt 4 and USB4?
Unlike earlier iterations of USB-C, which use Alt Mode for video support, USB4 and Thunderbolt 4 primarily use video tunnelling to transmit video over the USB-C connection. Video tunnelling dynamically allocates bandwidth for video and data to ensure optimized performance. If a device does not fully support video tunnelling, your Thunderbolt 4 or USB4-capable system can fall back to Alt Mode, ensuring compatibility with devices that support Alt Mode for video. So you don’t have to worry about a Thunderbolt or USB4 connection supporting USB-C Alt Mode!
Troubleshooting For Alt Mode
When using a USB-C video cable, adapter, docking station, or hub, it's important to ensure that your laptop supports Alt Mode. If you encounter any issues, the following steps can help you troubleshoot and determine why video may not be working through your USB-C Alt Mode cable or device.
-
First and foremost, check to ensure that your system supports Alt Mode. This is vital as Alt Mode is an optional feature that not all manufacturers include on their systems.
- If your system does not support Alt Mode, unfortunately, this is a hardware limitation, and there is no workaround for achieving Alt Mode compatibility. However, it’s possible to still drive external monitors through DisplayLink.
- Reboot your system and perform a power reset on your docking station or hub (if applicable)
-
If you are using a docking station, ensure that you are using a USB-C cable that supports Alt Mode.
- Not all cables are created equal—USB-C cables that support USB 2.0 only or “charging only” cables are not built to support video. To ensure compatibility, all of our Alt Mode-capable products will come with a USB-C cable that supports this feature.
- Do not use USB-C to USB-A adapters, as they are not designed to support video transmission.
- Be sure to check your operating system's display settings. The connected display can sometimes be disabled within the display settings, or the resolution and refresh may need to be adjusted to match what your device or display can support.
- Check if your Alt Mode-capable device has any firmware updates listed specifically for Alt Mode.
- Ensure that your system is up to date with all its latest drivers, firmware, and BIOS, especially your USB and internal graphics controller. Outdated drivers can often lead to connectivity issues, and at times, a BIOS update is needed, which the system manufacturer will generally mention on their official support page.
- Check BIOS and UEFI settings; some manufacturers add settings that control USB-C functionality. Ensure that your settings are enabled and correctly configured for Alt Mode.
- Test out another USB-C port on your system if you have more than one. This is beneficial in determining if the issues are related to the specific port.
Benefits of USB-C Alt Mode
Alt Mode over USB-C provides a direct connection to the GPU, allowing you to take advantage of the capabilities of your built-in GPU. This ensures native-level performance without the need for extra software or drivers. As a result, your USB-C Alt Mode-connected display will have reduced latency compared to other methods of adding additional displays, making it perfect for users who require sharp and detailed visuals at optimal refresh rates. Unlike traditional video connectors like HDMI or DisplayPort, which only support video, a USB-C connection with Alt Mode is more flexible and multifunctional, allowing a single connection to carry video, data, and power delivery.

How to Use Two External Displays with the Lid Closed on MacBook Air and MacBook Pro M3
Overview
With the release of Apple’s M3 CPU chips and the Sonoma 14.6 update your base MacBook Air and MacBook Pro systems with M3 chips can now host two external displays natively in clamshell mode. This guide will walk you through the process of setting up and using two external displays with the lid closed on your MacBook Air or MacBook Pro equipped with an Apple M3 chip.
Requirements
Before getting started, ensure you have the following:
- MacBook Air or MacBook Pro with an Apple M3 chip.
- macOS Sonoma 14.3 or later for an M3 MacBook Air or macOS Sonoma 14.6 or later for an M3 MacBook Pro.
- Two external displays with compatible video inputs (e.g., HDMI, DisplayPort, USB-C).
- A dock or graphics adapter can be used as well.
- External keyboard and mouse (wired or wireless).
- Power adapter or power source for your MacBook
- A docking station that provides adequate charge can be used in place of the native power adapter, be sure to check the wattage your dock provides.
Steps to Set Up Dual External Displays with the Lid Closed
1. Set Up Your External Keyboard and Mouse
- If you’re using a wired keyboard and mouse, connect them directly to your MacBook or Plugable dock.
- For wireless peripherals, ensure they are paired with your MacBook and functioning properly.
- An AC adapter/power cable of some kind will also need to be connected for clamshell mode to function properly. This adapter can be one from a docking station or the included Apple adapter.
2. Connect Your Displays
- Connect the first external display to your MacBook using the appropriate cable (e.g., HDMI, DisplayPort, USB-C)
- Close your laptop’s lid.
- Connect the second external display using a similar method.
- Ensure both displays are powered on and set to the correct input source.
3. Configure Display Settings
- Open System Settings on your MacBook.
- Go to Displays.
- You should see both external displays listed. Arrange them according to your preference by dragging the display icons.
- Adjust the resolution, refresh rate, and other settings as needed.
4. Enable "Clamshell Mode" (Lid Closed Mode)
- With your external displays connected and set up, close the lid of your MacBook.
- Your MacBook will automatically switch to "Clamshell Mode," where the internal display turns off, and the external displays become your primary screens.
- Ensure your MacBook is connected to a power source to prevent it from entering sleep mode.
5. Check the Display Arrangement
- With the lid closed, check that the external displays are functioning as expected.
- If necessary, re-open the Displays settings to adjust the arrangement, resolution, or other preferences.
Troubleshooting Tips
- No Display on External Monitors: If the external displays are not showing anything, open the lid of your MacBook and check the connections.
- MacBook Sleeps When Lid Is Closed: Make sure your MacBook is connected to a power adapter. Clamshell Mode requires the MacBook to be plugged into an external power source.
- Performance Issues: If you experience lag or performance drops, try lowering the resolution or refresh rate of the external displays.
Thunderbolt Dock Users
With these steps, one can use Plugable Thunderbolt docks to enjoy a dual-display setup without the need for additional software installation. The dock leverages the native capabilities of the MacBook Air M3 and MacBook Pro M3, providing a straightforward and efficient solution for expanding your workspace with additional USB ports, audio, and ethernet (as well as the dual displays).
Additional Resources
If you should need any assistance with your setup, please feel free to reach out to our support team at support@plugable.com.
I installed the macOS InstantView Application on my Mac running macOS 15 in order to use my Plugable Silicon Motion-based docking station or video adapter. When I connected my Plugable device to my Mac, I received a prompt to 'Allow' the application for one month. What is this prompt, and what should I do?
In brief, the prompt is part of a new security feature Apple introduced with macOS 15 Sequoia.
For reference, an example of the prompt is included below:
In order to use your Silicon Motion-based product, you must click the ‘Allow For One Month’ button within the prompt you received. In one month’s time, you will be prompted to renew this authorization for an additional month. This renewal process will continue each month thereafter.
To expand further, when initially installed the macOS InstantView Application must be granted ‘Screen Recording’ permission within the macOS Security & Privacy settings in order to function.
*** An important note, the macOS InstantView Application does NOT in fact record or store any information. This permission must be granted in order for the macOS InstantView to access the information it needs in order to generate the image shown on the Silicon Motion driven displays. ***
With the release of macOS 15 Sequoia, Apple has instituted a new policy whereby this permission must initially be allowed for one month and then be renewed on a monthly basis. If the permission is not renewed, then the Silicon Motion device will not function.
How many displays can be added to a computer via USB?
Overview
Modern computers are limited in regard to the number of external displays that can be directly connected or “natively supported.” These limitations are determined by the capabilities of the host computer’s internal graphics processing unit (GPU) and the number of physical video connection ports available.
Products available from Plugable that use technology from DisplayLink or Silicon Motion provide the ability to connect multiple external displays to a computer via USB once the required software driver is installed, which allows one to workaround the host computer’s internal limitations.
Such technologies are typically referred to as ‘indirect display’ technologies because the USB connection means that the displays are NOT connected directly to the host computer’s GPU.
The total number of external displays possible via an indirect display technology can vary due to a number of factors:
- The technical specifications of the host system
- Limitations of the host operating system in regard to how many displays can be addressed
- Limitations of the USB subsystem, in regard to how many devices can be physically connected and recognized by the host system
- The capabilities of the specific indirect display technology in use
Speaking in general, with most modern computers at least four external displays can be added via USB graphics technologies and in some instances up to eight displays are possible. Note these are in addition to the number of native external displays your system supports, which ranges from 1-4 on most modern systems.
Number of indirect displays supported by Plugable
| Windows | macOS | ChromeOS | |
| DisplayLink | 8 - 1920x1080 4 - 3840x2160 |
4 - 3840x2160A | 8 - 1920x1080 4 - 3840x2160B |
| Silicon Motion | 8 - 1920x1080 4 - 3840x2160 |
4 - 3840x2160 | 8 - 1920x1080 4 - 3840x2160 |
A. Total includes any displays added via Apple’s Sidecar feature → https://support.apple.com/en-us/102597
B. Performance is dependent upon the specifications of the host system. Chromebooks using lower-spec CPUs and GPUs may support fewer displays
*** Please see important information within the ‘Performance and Technical Limitations section below ***
Performance and Technical Limitations
When using products based an indirect technology, the number of external displays that can be added to a computer (and are supported by Plugable) will vary depending upon which operating system is in use and certain technical limitations:
Host resource use
An indirect display device is in essence a ‘virtual’ GPU that relies on the capabilities of the host computer’s CPU and physical internal GPU in order to generate the image shown on the attached displays.
With each indirectly connected display added to the host, more CPU and GPU resources are required. As more displays are added, the amount of resource use may impact both the performance and stability of the computer and displays. It should be noted that the resource load will vary depending on the type of content being shown within the indirectly connected displays. For example, static content (such as an office application) will require less resources as compared to dynamic content (such as a video).
USB device connection limit
Modern computers have practical limits in regard to the maximum number of devices that can be connected to the host’s USB subsystem.
These limits will prevent USB devices from being recognized by the host when a certain number of devices are connected.
The total number of USB devices that can be connected can vary from system to system, as well as the specification of the USB protocol in use.
Speaking in general, host computers that supported only USB 2.0 could recognize and use a large number of external USB devices.
Host computers that support USB 3.0 or later versions of the specification have limitations in regard to the number of external devices that can be connected to ensure the level of performance does not drop below a certain threshold.
How To: Set the Display Refresh Rate in Windows 11
Many modern displays can support above the default 60Hz refresh rate, however this may need to be manually set within Windows 11. Please note, not all computers, graphics adapters, and docking stations can support all resolutions and refresh rates.
Setting the Display Refresh Rate in Windows 11
1. Right-click on the desktop and select Display Settings from the drop-down menu
2. Scroll down to the Related settings subsection and select Advanced display
3. At the top of the Advanced display window, select the external display from the drop-down menu
4. From the Choose a refresh rate drop-down menu select the desired refresh rate
Refresh Rate Limitations
With Windows 24H2 and newer, dynamic refresh rates are supported, this allows the system to adjust the display refresh rate to save power, up to the selected refresh rate. As a consequence of this new mode, when selecting the display refresh rate you may see an asterisk. This indicates that selecting the specific refresh rate may reduce the display resolution or image quality in order to prioritize the refresh rate. This exposes the refresh rate option from the display even if the display cable or computer is incapable of supporting that refresh rate at the native resolution and is the intended behavior per Microsoft. [1]
In the screenshot below the left side shows the 4K 120Hz capable display limited to 60Hz refresh rate without asterisks, and on the right the same display after setting the refresh rate to “120 Hz*”, the “Desktop mode” resolution has been reduced to 2560 x 1440 (1440p) instead of 3840 x 2160 (4K UHD). Unlike when using the display scaling option this also causes a reduction in image quality. On the right side asterisks are no longer shown in the refresh rate list. Setting the refresh rate back to 60Hz does not change the resolution, you will have to go back one page and set the resolution manually.

Is this safe to use if my computer doesn't support USB-C Power Delivery?
USB-C Power Delivery (PD) is negotiated between the power-sourcing equipment (e.g., a dock or multiport hub) and the connected host device. During this negotiation, the device offering power communicates its capabilities, and the host determines whether it can accept the power. If the host does not support Power Delivery, no power will be sent to the computer over the USB-C connection. This will allow you to take advantage of other capabilities such as data transfer or video output without risking damage to the computer.
Is there a way to add more displays to my dock?
Extra displays can be added to your docking station by using USB graphics adapters. This allows you to expand your workspace beyond the number of displays natively supported by your dock or computer.
Here’s how it works:
- Ensure your dock has open USB-A or USB-C ports to connect the USB graphics adapter(s).
- Select a Plugable USB graphics adapter compatible with your operating system and monitor specifications. Feel free to contact Plugable support (support@plugable.com) for assistance in selecting the appropriate adapter for your setup.
- Download and install the driver from the "Downloads" section of the product page for the USB graphics adapter on Plugable's website.
- Plug the adapter into an available USB port on your docking station.
- Use an appropriate video cable (e.g., HDMI, DisplayPort) to connect the adapter to your monitor.
Important Considerations:
- Windows supports up to 8 DisplayLink/SiliconMotion-based monitors.
- macOS has a hard limit of 4 DisplayLink/SiliconMotion-based monitors.
- USB graphics adapters use bandwidth and system resources. Connecting multiple adapters can reduce performance.
Why is the Alt Mode video output on my dock not working?
Alt Mode video works by creating a direct pipeline from the host device's graphics processor through USB-C to the dock which allows it to output video to connected display. This relies on a few key factors to function correctly, including the host device's graphics processor, the host device's USB-C port, and the cable used to connect the dock.
It's recommended to check these possible causes if the Alt Mode video output on your dock is not working:
- USB-C Port Limitations: Not all USB-C ports support video output (Alt Mode). Check your host device's specifications to confirm it supports Alt Mode video output.
- Incompatible USB-C Cable: Some USB-C cables support power and data, but not Alt Mode video. Use the USB-C cable that was originally included in the box with your dock to ensure it supports Alt Mode video output.
- Incorrect Host Connection: Ensure you’re connecting to the correct USB-C port on the dock, typically labeled a laptop icon. Other USB-C ports on the dock may not function for connecting the dock to a host device, and using them could result in no function.
- Outdated Drivers: Ensure your operating system and graphics drivers are up to date. USB-C Alt Mode primarily relies on the laptops graphics processor to produce video, so outdated drivers can often cause issues.
How Can I Check the Ethernet Adapter Link Rate on my Mac?
One helpful way to identify your ethernet link rate speed is through the System Settings app in macOS. This can help us identify if your Plugable ethernet adapter is negotiating either 1Gbps or 2.5Gbps network speeds. Some routers have a mix of 1Gbps or 2.5Gbps ports, and in the macOS System Settings this will be shown in the Speed field.
In this example, we will be analyzing our USBC-E2500, which is a 2.5Gbps ethernet adapter. This method applies to all of our ethernet adapters, such as:
Navigate to the Network section, select the entry named “USB 10/100/1G/2.5G LAN” with the Green - Connected icon. Expand the Details button, and go to Hardware.
In the field that says Speed, you should see 2500Base-T if the ethernet adapter is connected to a 2.5G ethernet LAN port on your router. If you see 1000Base-T, this means the adapter is connected to a 1G ethernet LAN port. If you are expecting faster network speeds, please see your router's documentation on its multi-gig LAN port.
Choosing the Right USB Type-C Cable for Your Docking Station
At Plugable, we rigorously test our docking stations with the included accessories to ensure they work seamlessly together. One key reason for using the included cable is that not all USB Type-C cables on the market support the same features. Therefore we strongly recommend using the USB Type-C or Thunderbolt cable that comes with your Plugable dock for best results.
Understanding the differences between charging and data cables is essential to fully enable your new docking station, or if you are ever in need of a replacement or longer cable for your docking station. Let’s break it down.
USB Type-C Cables: Charging vs. Data
USB Type-C cables may look identical, but their capabilities can vary significantly. Unfortunately, the USB specifications do not require cables to be clearly labeled, which can make identifying the right cable a challenge.
There are two main categories:
USB Type-C Charging Cables
Charging cables are among the most common Type-C cables available. They typically support:
✔ USB 2.0 data (up to 480Mbps)
✔ USB Power Delivery for charging devices
These cables are often included with smartphones, tablets, and some laptops. They are also frequently sold specifically for charging purposes. However, they lack the necessary conductors for high-speed data transfer and video output.
Fully Featured USB Type-C Cables
Fully featured USB Type-C cables offer full functionality and are required for docking stations. The cables we include with our USB Type-C docks support:
✔ USB4 or USB 3.0/3.1 data (5Gbps or faster)
✔ USB 2.0 data
✔ USB Power Delivery
✔ USB Type-C DisplayPort Alternate Mode for video output
These cables ensure full compatibility with our docking stations, allowing for both high-speed data transfer and external display support.
Thunderbolt Data Cables
Thunderbolt cables are a specialized subset of USB Type-C data cables. They are Intel-certified and typically marked with the Thunderbolt logo (⚡).
✔ Interchangeable with USB Type-C data cables when using USB 3.x devices
✔ Required for Thunderbolt devices to ensure proper functionality
If you're using a Thunderbolt docking station or device, a certified Thunderbolt cable is essential for maximum performance.
What Makes These Cables Different?
The key difference lies in the internal wiring:
🚫 Charging cables lack the conductors required for high-speed data (USB 5Gbps or higher) and video output. Even if a device supports USB Type-C DisplayPort Alternate Mode, a charging cable won’t transmit video.
✅ Data cables include additional wiring to support higher data rates, video output, and greater flexibility in bandwidth allocation.
How Can I Tell the Difference?
🔎 Charging cables are generally thinner and may have smaller connector grips, as they often lack electronic markers. They are typically advertised as:
- "Charging cable"
- "480Mbps data rate"
- Advertised primarily for phones and tablets, not laptops
🔎 Data cables are usually thicker and slightly more expensive due to their additional complexity. Look for statements such as:
- "USB 3.0/3.1," "USB4," or "Thunderbolt"
- "5Gbps" or faster data rates
- Mention of video support for use with external displays
⚠ Cable Length Matters!
Fully featured data cables are typically limited to 1 meter (3.3 feet) to comply with USB Type-C specifications. Charging cables, on the other hand, can be much longer.
Need a Longer or Replacement Cable?
If you need a replacement or a longer cable for your USB Type-C or Thunderbolt docking station, consider these options:
For USB 3.1/3.2 Type-C Docking Stations:
🔗 USB Type-C 10Gbps 1m (3.3ft) Cable
For Thunderbolt & USB4, and USB 3 Type-C Docking Stations:
🔗 Thunderbolt 4 40Gbps 1m (3.3ft) Cable
🔗 Thunderbolt 4 40Gbps 0.8m (3ft) 90° Right-Angle Cable
🔗 Thunderbolt 4 40Gbps 2m (6.6ft) Cable
Note: The USB Type-C 10Gbps cable is only recommended for USB 3.x docking stations, not Thunderbolt docks.
Do Plugable docking stations support automatic Ethernet hardware address (also known as Media Access Control or MAC address) pass through from the host computer?
Plugable does not officially support automatic or automated MAC address pass through functionality from the host computer with any of our currently available docking station products.
As of this writing, the only current exception is the upcoming UD-7400PD docking station → LINK and we speak to its capabilities in this regard here → LINK
However, when our docking station products are used within a Windows environment such behavior can be approximated by other means. The methods to do so and their complexity can vary depending upon the Ethernet network technology on which the dock is based.
To be clear, Plugable does not officially support these approximated solutions. However, we wanted to mention them should they prove helpful to others.
With that said, Plugable docking stations will vary in regard to the Ethernet network chipset used within the product. For general reference, the specific Ethernet chipset used within the product will be listed within the 'Specifications' tab of the docking station's product page.
For example, here are the specifications for the Plugable UD-6950Z docking station which is based on DisplayLink technology, which also provides the Ethernet network chipset functionality.
Note, all Plugable docking station products based on DisplayLink technology will have the DisplayLink logo printed on the product. For general reference, we have a list of all of our DisplayLink-based docking stations available here --> LINK
A DisplayLink-based Ethernet adapter can be configured to use a 'virtual' MAC address that is manually configured within the Windows Device Manager via the adapter's 'Advanced' settings tab, specifically the 'MAC Address' field.
Manually entering a hexadecimal value for the MAC Address field will override the MAC address stored in the Ethernet chipset within the docking station product (in so far as it is presented to the Windows operating system).
To be clear, this only affects the current Windows installation. This does NOT change the Ethernet MAC address stored within the dock itself.
Further to this, Synaptics (the separate company from Plugable who created the DisplayLink technology and also developed the software), have additional options available for configuring a DisplayLink-based MAC address. Some of these options provide a certain level of automation, while others require manual inputs.
DisplayLink outlines the available options within this knowledge base article --> LINK which for general reference is part of their broader 'Corporate Deployment' knowledge base category --> LINK
To be clear, since DisplayLink develops the software DisplayLink also supports the Corporate Deployment options directly.
Should additional assistance be required in regard to the Corporate Deployment options, please contact DisplayLink directly for further assistance --> LINK
Plugable also offers docking station products based on a variety of Realtek, Intel, and ASIX Ethernet network chipsets. For those products, the only option available is to manually configure a 'virtual' MAC address in a similar manner to what we described above.
However, please note that the description of the option to do so within Device Manager will vary. For example, for Intel Ethernet chipsets the option will be called, 'Locally Administered Address'. When using Realtek Ethernet chipsets the option will be called, 'Network Address'.
