USB HDMI 4K UHD Disconnecting

I recently purchased two Plugable USB 3.0 to HDMI 4K UHD Video Graphics Adapters. I have them connected to a Lenovo PC and then connected to Lenovo C32q-20 Monitors. The issue is they are randomly disconnecting - and when this happens all items on these screens are then moved to my other screens. After a second or two they re-initialize and I can put things back as they were - but then randomly later they disconnect again. Do I need to make a setting change?

Just crashed again - ran diagnostics and emailed results to

Hi Scott,

Thanks for reaching out to Plugable support! I’d be happy to help with that display adaptor.

The first steps we’ll want to take is to make sure that the software used by the display adaptor is in a good state by reinstalling the DisplayLink software and running the DisplayLink cleaner tool. To do so, please follow these steps:

  1. Disconnect the display adaptor from the system (this is important so the unit resets). Please keep it disconnected until the last step.

  2. Uninstall any and all software with ’ DisplayLink ’ in the title that is present from within the Control Panel -> Programs and Features . Don’t worry if these entries are not present or if the process does not work, just move onto the next step.

  3. Download, extract and run the DisplayLink cleaner tool. (

  4. Once the Cleaner has been run, reboot (even if not prompted to).

  5. Now download and install the 9.4 M0 DisplayLink software. (

  6. Reattach the display adaptor to your system which will trigger the final portion of the installation.

Hopefully that will get things working for you.

Thank you for giving us a chance to help!

I followed these steps.
At first I thought the issue may be resolved but after just a few minutes I am still getting the random disconnects - and all active programs from these two screens are moved to my other monitors. They do come back on after a second or two but frustrating to have to move open programs back.

Received two new devices - after installation the issue appears to have been resolved.

Thanks to the excellent Plugable Support Team for all their assistance!!
