No, this is not possible. Please note that DisplayPort to HDMI cables (as with most cables involving protocol/signal conversion) are not bidirectional adapters, which means they only work in one direction -- from a DisplayPort output to a HDMI input. 

Connecting these type of cables backwards will not allow an HDMI output port (such as those on a dock) to function with a DisplayPort input on a monitor.

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:

1. Start by right-clicking on the Start button and select Power Options from the menu.
2. From the right side of the Power Options settings page, select the blue link for Additional power settings

   

3. From the choices present on the left-hand side of the Power Options window, please click on Choose what closing the lid does
4. Make sure the setting for When I close the lid under the Plugged In column is set to Do Nothing

   

5. 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:

1. Start by right-clicking on the Start button and select Power Options from the menu.

   

2. 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

   

3. Make sure the setting for When I close the lid under the Plugged In column is set to Do Nothing

   

4. 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 )

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:

1. Disconnect all USB devices from the docking station and put them aside for the moment.
2. Disconnect any displays connected to the dock's video outputs.
3. Disconnect any audio devices connected to the dock's audio ports (if present).
4. Disconnect the Ethernet network cable from the dock's Ethernet port (if present).
5. 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.
6. While in this state, reboot the laptop to test the behavior.
7. 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.   

There are various reasons and configurations that can benefit from having more than one network adapter present on a PC.

For users with newer networking products, featuring 2.5Gbps link rates or greater, it may be beneficial to prioritize that network connection over others on your PC that are still connected to your network/LAN.

Below is a list of pre-tested power adapters and corresponding power prongs/cables for Plugable docking stations that can be purchased on eBay if a replacement is needed.

If the power adapter for your docking station or region is not listed or if it out of stock on eBay please contact us at support@plugable.com and we will be happy to assist further.

We offer a 30-day return period for our replacement power adapters listed on eBay.

If your package is missing one or more of the items that should be included with your Plugable dock (included items are listed on a chart on the side of the box), start by double checking if the part is still in the packaging. Pieces can occasionally get stuck in the corners under the main insert in the box.

If you are still unable to locate the piece, please contact support@plugable.com with the following information:

1.  Amazon Order ID (or other proof of purchase) associated with your Plugable device.

2. A description of the parts that are missing from your order.

3. Your preferred shipping address (and a phone number associated with that address).

4. The serial number of your 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.

Unfortunately Plugable products do not support the Apple SuperDrive.

The Apple SuperDrive has stringent power requirements that can only be met by directly connecting the SuperDrive to your host laptop. As a result at this time Apple recommends only using their USB-C adapter cables. You can find more information on that here -→ How to connect the Apple USB SuperDrive

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.

The Plugable USB4 Dual HDMI Docking Station for Windows UD-4VPD relies on DisplayPort MST to support two HDMI external displays from a single USB Type-C connection when used with a compatible host computer.

Compatible Windows 11 notebook computers with USB4 or Thunderbolt 4 and support for DisplayPort 1.4 with HBR3 (High Bit Rate version 3) and DSC (Display Stream Compression) can support up to two 4K 60Hz displays. Unfortunately these technologies are not required to be implemented on all computers with USB4 or Thunderbolt 4 capability and not all systems will be capable of supporting these high resolution displays.

This docking station is also compatible with Windows USB 3 Type-C with DisplayPort Alternate Mode, and Thunderbolt 3 systems.  These host systems will have reduced external display resolution or refresh rate.

Apple Mac systems will only be capable of supporting a single extended display with this docking station, with limited refresh rates.  Additionally, when connecting two displays to the docking station, generally both displays will show the same desktop, applications, and mouse movements ( just like mirrored mode ).

Multiple display capabilities for USB4/Thunderbolt 4 systems:

• USB4/Thunderbolt 4 Windows systems with DisplayPort 1.4 HBR3 DSC (High Bit Rate 3 with Display Stream Compression) can support a single 8K (7680x4320) 60Hz display, or dual 8K 30Hz displays. Dual 4K (3840x2160) 120Hz displays, or dual 1080P 120Hz displays.
• Apple Silicon (M1/M2) Mac computers do not support DisplayPort MST (Multi-Stream Transport) technology, this can support a single display through this docking station, however if two displays are connected their outputs will be mirrored (the same desktop workspace will be displayed, with the same applications and they will not be individually usable displays, mirroring occurs in the docking station hardware and is not configurable within macOS).  Apple Silicon computers can support a HDMI display up to 4K 60Hz.

Multiple display capabilities for Thunderbolt 3 systems:

• Thunderbolt 3 Windows systems  can enable up a single 4K 30Hz display, or two 1080P 60Hz Displays in extended HDMI displays.
• Thunderbolt 3 Apple Macs with Intel processors can enable a single 4K 30Hz display, or mirrored 4K 30Hz displays (mirroring occurs in the docking station hardware and is not configurable with macOS).

Multiple display capabilities for USB-C only Windows systems:

• USB-C DP Alt Mode MFDP Windows systems with DisplayPort 1.4 HBR3 with DSC (High Bit Rate 3 with Display Stream Compression) can support up to two external displays at 4K 60Hz, or one 8K 30Hz display.
• USB-C DP Alt Mode MFDP Windows systems with DisplayPort 1.4 HBR3 without DSC (High Bit Rate 3 without Display Stream Compression) can support up to two 1440P (2560x1440) 60Hz displays, or one 4K 60Hz display.
• USB-C DP Alt Mode MFDP Windows systems with DisplayPort 1.2 HBR2  (High Bit Rate 2) can support a single 4K 30Hz display, or two 1080P 60Hz displays.

Display Capability Table

Important Notes:

• Windows 10 and Windows 11 systems will try to mirror/clone attached displays by default upon first connect, it will be required to separate any mirrored/cloned displays and change them to be extended in the Windows Display Settings.
• Some Thunderbolt 3 Windows systems will only support a single DisplayPort stream, this limits the maximum refresh rate to 30Hz when using two 4K displays. Please check with your system manufacturer to verify dual displays via Thunderbolt 3 are supported. (a common example would be the popular Intel NUC hosts which usually only support a single display through Thunderbolt 3)
• High Refresh Rates (above 60Hz) may cause reduced system performance especially with multiple high refresh rate displays, this is most often a limitation of the computer's graphics hardware, not all computers can support high refresh rate displays.
• We do not support HDR (High Dynamic Range) or adaptive sync/variable refresh rate (such as AMD FreeSync or Nvidia G-Sync technologies)
• Notebook computers with dual-graphics controllers, for example Intel and NVIDIA, in a switchable graphics mode may have reduced maximum resolutions and refresh rates compared to either of the individual graphics controllers.
• Apple macOS does not support DisplayPort MST and can only support a single display connected to this docking station. If two displays are connected they may be mirrored (showing the same content) or only one display will be active and the second display will remain blank.
• Linux is not supported with this docking station, in testing Ubuntu 22.04 LTS, 23.04 and Fedora 38 were not able to reliably detect or enable the external displays connected to the docking station, capability may change with future releases or Kernel updates and we will reassess support as time goes on.

Terms and definitions:

• MFDP or Multi-Function DisplayPort: A USB Type-C port with DisplayPort 'Alternate Mode' capability to transmit native DisplayPort formatted video signal to a connected display or docking station.
  
• DisplayPort MST: Multi-Stream Technology, effectively "splits" the DisplayPort bandwidth between multiple displays, allowing a single DisplayPort connection to support multiple external displays.
• USB Type-C DisplayPort Alternate Mode or "Alt-Mode" for short: this is an optional USB Type-C port feature which allows for the USB Type-C port to support external displays like a native DisplayPort
• Thunderbolt DisplayPort: similar to USB Type-C DisplayPort Alternate Mode this allows for a display to be connected to a host computer through a Type-C port, however Thunderbolt tunnels DisplayPort data instead of providing dedicated conductors for video data.
• DisplayPort HBR2, HBR3: DisplayPort High Bit Rate 2 and High Bit Rate 3 sets the available bandwidth for a DisplayPort connection, HBR3 doubles the bandwidth of HBR2 allowing for higher resolution displays.
• Display Stream Compression or "DSC" for short: is a VESA developed "visually lossless" video compression technology to provide additional bandwidth on both DisplayPort and HDMI connections.  This allows for higher resolutions and refresh rates using the same physical hardware.
• CPU the Central Processing Unit is the computer's main processor handling most of the computational operations, manufacturers include Intel, AMD (Advanced Micro Devices), and Apple (M1/M2 Apple Silicon).
• GPU the Graphics Processing Unit is the computer's graphics processor handling graphics computations like drawing the display, and rendering 2D and 3D images. Manufactures include Intel, AMD, NVIDIA, and Apple (M1/M2 Apple Silicon).

If you are having issues with your HDMI display(s) not working at their expected native resolution from your TBT4-UDZ or UD-4VPD docking station HDMI outputs, and your notebook computer is equipped with discrete NVIDIA graphics (or hybrid AMD/Intel + NVIDIA graphics), you may need to install an earlier version of the NVIDIA graphics driver to resolve the low-resolution behavior.

This behavior with low resolution over HDMI (usually 800x600 or 720x576) is due to a what we believe is a regression with the NVIDIA graphics driver past version 532.03. Based on our internal testing and reports from customers any newer driver version at this time will cause this low-resolution behavior. 

It is our current recommendation that if you are running a newer version of the NVIDIA graphics driver and are experiencing this issue to roll-back to version 532.03 which can be found below:

https://www.nvidia.com/download/driverResults.aspx/204970/en-us/

Please note that this specific behavior only affects our TBT4-UDZ* and UD-4VPD docking stations and is currently under investigation (*TBT4-UDZ DisplayPort outputs are unaffected). Once there is a newer NVIDIA graphics driver available that does not exhibit this regression this article will be updated.

To update the NVIDIA Graphics Drivers to the compatible version: 
1) Download the latest graphics drivers from NVIDIA linked above, by clicking on the green "Download" button on this and the next page, save the drivers to the Desktop or Downloads directory 
2) Save and close any open applications, unplug the docking station from the computer, and connect the original power supply 
3) Navigate to the downloaded graphics driver, then right-click on the saved driver installation file and select "Run as administrator" to start the installation process 
4) Allow the NVIDIA driver installation through the "User account control" window 
5) Select the "Custom Installation" option, and on the "Custom Installation" screen, select the checkbox next to "Perform a clean installation" near the bottom of the window, then follow the on screen instructions to update the NVIDIA Graphics Drivers 
 - If there are any errors, please take a screenshot ( using the Windows Snipping tool, or screenshot shortcut [Win]+[Shift]+[S] and attach the screenshot of the error message to an email to ‘support@plugable.com’ and we will be happy to help 
6) When complete please restart the computer ( Start > Power > Restart ) before reconnecting the docking station

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.
