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.

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.

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.

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. 

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.

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.

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.

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.

Our Silicon Motion-based graphics adapters and docking stations are supported with macOS, albeit with potential limitations that one would expect with a directly connected external monitor.

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.

2. Navigate to your Downloads folder and double-click on the Silicon Motion driver download

2. Double-click on the 'SMI USB Display Driver Uninstaller' to begin the uninstallation wizard

3. Click the ‘Uninstall’ button

4. Enter your account password and click ‘OK’

5. After a few moments the process will complete. Click the ‘Restart’ button to complete the removal process.

Yes! As long as the software drivers for both Silicon Motion and DisplayLink-based products are installed on the same computer these two USB graphics solutions can work together and be used at the same time.

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:

1. 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
2. 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
3. Once the uninstallation has completed running, restart the host system (even if not prompted to)
4. Download and install the latest version (that we recommend) of the Silicon Motion software driver
5. 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

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

If you have purchased a Plugable product to use with your Apple SuperDrive, and would like some additional assistance please do not hesitate to reach out. You can do so by emailing support@plugable.com, or going to Plugable.com/Support.

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.

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.
