The first adapters available with the the DisplayLink DL-6950 chipset, our USB-C Dual 4K adapters support two external monitors at resolutions up to 4K@60Hz each and offers a Gigabit Ethernet port for connecting to your network via Ethernet cable. Our adapter is compatible with systems with a USB 3.1 Type-C Gen 1 / Gen 2 or Thunderbolt 3 ports and leverages the increased data throughput of these technologies.
The Dual 4K DisplayPort adapter offers two Dual-Mode DisplayPort 1.2 (DP++) ports and is backwards compatible with previous DisplayPort specifications.
To achieve 4K@60Hz each connected monitor and cable must support the desired resolution and refresh rate.
DisplayPort equipped monitors and DisplayPort cable must support DisplayPort 1.2 specification in order to support 4K@60Hz. While backwards compatible with DisplayPort 1.1 standards, the resolution will be limited to 4K@30Hz if the display or cable does not support DisplayPort 1.2 specifications.
Our adapter is compatible with most modern laptops and desktops running Windows 10, 8.1 and 7 and requires the DisplayLink graphics software to be installed. Popular Windows systems with a USB Type-C/Thunderbolt 3 port include the Dell XPS 13 (9350, 9360) and XPS 15 (9550, 9560), Lenovo Yoga 720-13IKB, Lenovo Yoga 900-13ISK, HP Spectre x360 13″ (13-ac013dx), and more.
It is not supported with macOS, Linux/Unix or ARM based Windows operating systems (such as Surface RT).
Does not support HDCP copy protected content (Blu-Ray, Netflix, Amazon Prime video, etc.). Our adapter also does not support DisplayPort MST daisy-chain connections or Dual-Link DVI conversions.
Does not support monitors with 1366×768 optimal resolutions.
Additionally, the Gigabit Ethernet port requires a Full-Duplex network connection from the connected network device (router, switch, etc.).
For optimal performance the below system specifications are recommended:
Operating System: Windows 10, 8.1 or 7
CPU: Intel SkyLake i3 or Intel Core i7, AMD A10 at 2.0GHz or better
Graphics Processor: Intel HD 4000, AMD Radeon HD 8650, NVidia GeForce 7xxM or better
Memory: 8GB RAM
Host connection: USB Type-C 3.1 Gen 1 and Thunderbolt 3 port
Please note: DisplayLink had updated the minimum system requirements after the packaging design was finalized.

Quick Start Guide
Why can’t I get the same 4K @ 60Hz resolution across all monitors?
To achieve 4K@60Hz each connected monitor and cable must support the desired resolution and refresh rate.
There are several different reasons why a 4K display would be limited to 4K@30Hz using our adapter. We would recommend first checking:
- Monitor specifications to ensure that it can support 4K@60Hz from the desired input port. DisplayPort input ports must be DP 1.2 specification.
- Ensure that the DisplayPort cable is DP 1.2 compliant.
If my adapter worked for some time, and now isn’t working, what should I do?
First check all cable connections. If that isn’t it, an operating system upgrade can require a software update. Visit https://plugable.com/drivers/displaylink/ to download and install updated drivers. If this doesn’t solve the issue, please email firstname.lastname@example.org and we’ll be happy to help!
What can I do about a failure when installing the DisplayLink drivers?
We’ll be able to help! Please run our support tool at https://plugable.com/support/plugdebug/ and email the .zip it generates to us at email@example.com and we’ll see what’s wrong and be able to help. Thanks for your patience!
Why are the System Requirements on the packaging different than the Minimum System Requirements on the product page/Amazon listing?
After packaging design was finalized and in production DisplayLink (the manufacturer of the DL-6950 chipset) had updated the minimum system requirements.
Does the adapter support audio pass through to my display with built-in speaker?
Yes, if your display has built in speakers and are connected to our adapter via DisplayPort or HDMI, audio should be sent to the display when the Plugable Audio device is set as the Default Playback Device within Windows’ Sound settings.
When I have two displays with built-in speakers connected to the adapter audio is sent to both displays. Is this expected and how do I resolve this?
This is expected because DisplayLink has enabled this functionality to send audio to both connected displays. As a workaround, we recommend muting the display from which you do not want audio to be playing.
After a recent update, when I use Chrome on my Mac with a USB graphics device, the window looks distorted. Is there a workaround? While we don't support our USB graphics devices on Mac, we have reproduced this behavior during internal testing. It appears there has been a regression in the current version of Chrome for OS X (Version 46) which causes graphical distortion when Chrome windows are in use on USB-attached monitors.
Until this issue is fixed in a future version of Chrome, the best current workaround is to disable hardware acceleration in the Chrome settings. To do so: Click the Chrome menu header -> Preferences -> Settings -> Show advanced settings -> Scroll down to "System" -> Uncheck "Use hardware acceleration when available".
To help make Google aware of the issue so they can properly prioritize fixing it, affected users can report the regression to Google using the built-in bug reporter: Preferences -> About -> Report an issue
I installed the adapter on my laptop and everything works well with the laptop lid open. However, when I close the laptop lid the monitors connected to the dock turn off. Can I use this adapter with my laptop with the lid closed?
Windows has special power management settings that control what happens when the laptop lid is closed. If this happening, these settings need to be changed. Please right-click on the Start button and select ‘Power Options’ from the menu.
From the choices present on the left-hand side of the Power Options window, please click on ‘Choose what closing the lid does’. ** Important note – if you are running the Creators Update (or newer) to Windows 10, you will have click on the ‘Additional power settings’ option to access this window **
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.
What do the green and amber LEDs on the Ethernet port on the adapter indicate?
The green link LED on the Ethernet port on the adapter is an indication that the Ethernet cable plugged into the port is live and it stays steady as long as the live cable is plugged in. The blinking amber activity LED is an indication that data is transferring through the port. Both these LEDs will not light up when:
- The DisplayLink driver for the dock has not installed properly or is corrupted
- The Ethernet Cable plugged in is not live or is faulty
- The network device to which the dock is connected only supports half-duplex communication (see next FAQ question below)
- The port has failed
When I plug an Ethernet cable into the dock, none of the LEDs light up, and I do not get assigned a valid IP address. What could be causing this?
The Ethernet controller in the docking station requires a full duplex connection. Half duplex connections are not supported.
Often, the issue is caused by older Ethernet hubs and/or cabling that do not support full duplex connections.
Why does the “Display Color Calibration” tool in Windows seems to have no effect on the display(s) attached to my dock?
The DisplayLink driver does not support color calibration functionality. 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.
I use an application to change the color of my display to make it easier to see (like the f.lux application) but it doesn’t seem to affect the display I have connected to the dock. Why is this?
As mentioned above, the DisplayLink driver does not currently support this type of color adjustment so applications like f.lux will not affect displays connected to the dock. DisplayLink (the maker of the chip in the dock and author of the driver) is working to add this functionality in the future. Please see this post on the DisplayLink website for more information and the current state of the project.
While I can adjust the brightness of my internal laptop display or directly connected external display using the Windows Display Settings application, this option is grayed out and not available for the displays attached to the dock. Is something wrong?
Windows does not have the ability to adjust the brightness of a USB-attached display, so the behavior is expected. We recommend making use of the display’s internal on-screen menu options to adjust the brightness.
I cannot use my Intel, Nvidia, or AMD/ATI graphics utility to manage the monitors connected to the dock. Why is this?
The utilities provided by Intel, Nvidia and AMD/ATI are designed to only recognize and work with graphics adapters made by their respective manufacturers and they will not recognize USB-attached displays connected to the dock. It is recommended to use the facilities built-in to Windows to manage the displays connected to the dock (‘Display Settings’ on Windows 10 and ‘Screen Resolution’ on Windows 8.1 and 7).
Are Plugable USB video adapters or docking stations 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, but Plugable does not provide support for doing so due the complexity of multi-monitor touch screen setups.
