Usb-c 4k only detect 1 monitor with latest windows 11 update

There is a windows11 update today, suddenly usb-c 4k docking station stops working. I have 3 monitors connected through usb-c station, but windows 11 suddenly only display 1 monitor, but not other 2. In “Settings”, try to detect multiple monitors, it doesn’t detect at all. I tried to un-insall display link driver and re-install it again without any luck.

Laptop is DELL XPS 15 9500

Here is the Windows 11 latest version and build:

Edition Windows 11 Home
Version 21H2
Installed on ‎11/‎22/‎2021
OS build 22000.376

Here is display driver version: 10.1.2875

FYI, I tried run “Device Manager”, under “Display adaptor”, there is no “plugable” found.

Please advise.

Hi Charles,

Thanks for contacting us! I am sorry this is not working as expected.

Based on your description of the behavior, our first step is to get some additional information from your system, to check for any other software updates that may be required to re-enable the docking station’s two DisplayPort outputs.

If you would, please keep the dock connected to the computer with monitor(s) connected tot he docking station (even though two are not working) and attach the output of our diagnostic utility PlugDebug ( ) to an email to ‘’ with the subject line ‘Ticket #364457 - Attention Pat’ as this will allow us to examine some log files from your system to help determine the next steps.
