USB 3.0 Dock & Windows 11

Hi all,

I’m currently using the beta release of Windows 11, and yesterday (9/30/21) we received an update to DisplayLink (10.1.2875.0). A situation occurred that I thought I’d post here as an FYI.

I’ve been using the USB 3.0 dock to handle multiple displays from my laptop. The dock has worked perfectly since I purchased it, and has allowed me to free up desk space by stowing my laptop under my desk. However, after the update my monitors no longer display anything unless the laptop lid is open. Lid open, everything is fine…lid closed, monitors receive no signal.

I’ve left a post on DisplayLink’s forums so they’re aware of the issue I ran into. If you happen to be using the USB 3.0 dock to rock dual/multiple monitors you may want to wait on upgrading to Windows 11. If I receive any updates I’ll try to post them here as well.

Take care!

Hi Rick,

Thank you for posting and sharing your experience, and we appreciate the detail you provided.

My impression based on your description is that you are using the Plugable UD-3900 docking station → Please correct me if I am mistaken.

Presuming for the moment that my understanding is indeed correct, Windows has special power management settings that control what happens when the laptop lid is closed.

Your description of the events suggests that these settings may have changed, which in turn may be the cause of the new behavior you are experiencing.

As a result, may I ask you to please follow these steps in order to see if the behavior changes?

  1. Please ensure that an external power adapter is connected to the laptop. This is important because the UD-3900 dock does not provide power to the host PC.

  2. Please click on the ‘Start’ button. From within the ‘Start’ menu, type ‘lid’ (without the quotes) in the search area at the top of the window (example screenshot below):

  1. Click on the result that says, "Change what closing the lid does’.

  2. From within the new window that appears, change the setting for ‘When I close the lid:’ to ‘Do nothing’ under the ‘Plugged in’ column. Annotated example screenshot for your reference:

  1. Click on the ‘Save Changes’ button at the bottom of the window to confirm the change.

  2. Close the laptop lid in order to test the behavior again.

Please let us know if that information helps, and thank you again for sharing your experience in our community!

Hi Bob,

That fixed it! Throughout the Windows 11 beta each update has changed my settings (I’ve lost count of how many times I’ve had to reapply my desktop), so I should have checked this myself. Thanks for the reply. I’ll update my post on DisplayLInk’s forum as well.

Take care!

Hi Rick,

Thank you for getting back to us with the update, and you are of course most welcome for the help. I am glad to hear that everything is now working as expected after having made the changes we described previously.

A quick note, you mention that, “I’ll update my post on DisplayLInk’s forum as well.” As I type this at 5:57 AM PDT on 10/1/2021, the DisplayLink support forum → is not working as expected. We have reported this issue to DisplayLink, and they are working to address it presently.

Thank you, and please have a good weekend!


Hi Rick,

Previously I mentioned that the DisplayLink support forum was not working as expected. I am happy to report that this problem has been resolved, and the DisplayLink forum is working as of today →

I wanted to make mention should you wish to update your ‘other’ post regarding this topic →

Good afternoon. I am also using the preview version of Windows 11 and I have the same dock. It has worked perfectly with my 2 monitors. However, after I upgraded to Windows 11, the monitor I have plugged into the HDMI port on the dock is stretching or misshaping windows on the screen. The monitor is an Acer S371HK. It work OK just sort of aligned wrong. I checked all driver levels and they are all current. Any suggestions would be great.

Hi Chuck,

Thank you for posting!

The behavior you describe sounds substantially different than that of the original poster of this thread. As a result, at this time I do not believe that the cases are related.

Based on your description of the behavior, I would suggest reaching out to us directly via a new email to with the following information:

  1. The Amazon Order ID number for your Plugable purchase

  2. A PlugDebug file → from your PC while while the dock is connected to the system and the Acer monitor is connected to the dock (even if not working as expected).

This information will help us determine the next steps.

A few important notes:

  • We do not officially support the preview releases of Windows 11. We only support the final public release made by Microsoft on October 5th

  • Please do not post the information we requested above here in our public forum (it contains personal information). Please only include in your direct email

Thank you for giving us the chance to help!
