Minisforum UM480: picture crash at high resolution

[vitaleg]

Got igpu passthrough but it works only on low resolution (800x600).

When Windows is loaded it runs at 800x600 resolution by default, in the device manager the device shows that GPU is in “disabled” (status code 22), when I manually start the device I see a black screen or this:

At the same time, interestingly enough, I can see the mouse cursor and I can move it.

It doesn't seem to depend on Windows version or machine type (BIOS/UEFI). I have the exact same situation on Windows 10 (BIOS) and Windows 11 (UEFI).

AMD Adrenalin works, iGPU modes can be set (when I'm running without primary gpu in pci).

Installing RadeonResetBugFix has no effect whatsoever.

Has anyone ever experienced anything like this?
