Windows 10: Windows 11 dual GPURX580 , secondary GPU - no signal

Hi, I have two RX580 installed, worked like a charm in Win10 with no patches. I've just upgraded from Win10 to Win11, monitors connected to the secondary GPU do not work.I've tried to run SFC, reinstall drivers, reconnect monitors, change graphic settings - nothing works. At the same time I can see both cards in Device Manager and in AMD Radeon Software, so I believe this problem is not driver-related and definitely not hardware-related have secondary OS installed on the same PC - still no issues there. Noticed that there are quite strange Graphics options: What's the point of power saving/h

:)

• Secondary drive not visible in disk manager

Steps to replicate issue:

• Installing 1909 update

Steps to resolve issue:

Since updates can only be delayed for so long, an actual fix would be appreciated.

 

Is there a way to force a program to use a secondary GPU?

I have 2 GPU's (Nvidia GTX 970 and 1080) and I want to force a program to use the 1080 for certain programs/games. Going to Settings>System>Display>Graphics Settings should give me the option to switch GPU's. Unfortunately it does not list both of my GPU's
nor does it allow me to change to another one, only the default GPU is chosen (the 970). This is a desktop computer and I have tried the Nvidia control panel and UEFI settings without much luck. If I tried selecting a program to run on my 1080 (through the
Nvidia control panel), it would still run it on the 970. I have tried switching the GPU's around with not much luck there either. If I can suggest to Microsoft the option in the Graphics Settings to list both GPU's for selection, that would be great. Otherwise
I don't know what to do. Does anyone have any suggestions? Thank you for your time.
