P53 GPU problem through ThinkPad USB 3.0 Dock since Windows Upgrade to 20H2

2021-04-23, 9:52 AM

Hello,

 

I'm having issues with my GPU (Nvidia Quadro RTX 3000) usage on 2 external monitors connected to my P53 using a ThinkPad USB 3.0 Dock since my laptop was upgraded to Windows 20H2.

 

Searching in the forums didn't reveal much... Here is what I found out so far:

- after installation of the Windows Upgrade, Photoshop started complaining about not finding a GPU and hence disabling the extensions using it. Also another program I'm using for working on photographs crashed (assertion failed SystemInformationWin.cpp:282"gpusWmi.size() <= gpusEnum.size()" "Found more GPUs via WMI than EnumDisplayDevices.)

- un-installing 20H2 upgrade and going back to the previous version of Windows solved the issue. So it's definitely connected to this.

- all latest Lenovo updates and Windows updates have been installed.

- installing latest drivers from the DisplayLink website didn't help

- de-activating the internal graphics card (Intel UHD Graphics 630):

- graphics programs worked again based on Nvidia RTX3000

- Some other programs became terribly slow (e.g. entering text in an email)

- sleep mode disappeared from the

So this is not really an option

 

Are there any other possibilities I could try?

Thanks in advance!

Try reinstalling the displaylink drivers, or check if there are newer drivers available on  www.displaylink.com

 

EDIT: ah, ok you've already tried that.

Tech-Savvyness does not replace reading the fine manual.

hi, unfortunately I didn't find a solution, except de-activating the on-board graphics card in the BIOS. As I'm using the laptop most of the time plugged-in, this is a feasible solution for me - not sure how much more power consumption this brings though.

Not sure if you would like to take the older build version back.

 

Waiting for a Windows update may also take time for this new build version.

Just to clarify, this issue was with Windows 21H1 for me. I rolled back Windows to 20H2 and problems resolved.

 

You can add the following registry keys to stop the upgrade

 

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate

TargetReleaseVersion = 1 (dword)

TargetReleaseVersionInfo = 20H2 (string)
