[Question] How does this deactivate the HyperV Monitor?

[Tobi-La]

Hi,
this is no issue with Easy-GPU-PV, there just seems to be no discussion forum for this project.

Sadly I discovered this too late and setup a few VMs myself. I am using Sunshine and VirtualDisplayDriver, which are much better for my usecases anyway. I realized that performance is very bad when having hyperv + vdd active and after a lot of trial and error with deinstalling and activating / deactivating hyperv display adapter and monitor drivers I managed to deactivate the HyperV Monitor. It came back on restart, so I wrote a script which deinstalls the driver of the hyperv display adapter, searches for new connected hardware and deactivates the display adapter, which deactivates the monitor so windows only displays my own virtual display driver. However, I tried this vulkan workaround (#342) and played around some more with it, now I can't get the hyperv monitor to be deactivated again.

Since from what I read the monitor simply deactivates when you deactivate the hyperv display adapter, what does Easy-GPU-PV do to achieve that?

Thanks for your help!

The only line I found when going through the project is
"Get-PnpDevice | Where-Object {$.friendlyname -like "Microsoft Hyper-V Video" -and $.status -eq "OK"} | Disable-PnpDevice -confirm:$false"
This simply disables the adapter i think. Is that enough for you for windows to only recognise 1 display? If I just deactivate Microsoft Hyper-V Video there is still a second monitor displays in the device manager and in the display configuration. Weirdly after reenabling it again I can't get back to the state where I had it disabled without the monitor popping back up .
