HI JustJoshin,
I am able to select the gpu on the Windows 10 VM how ever when i boot it up nothing comes out any of my video out puts, i have tried hdmi, displayport(adapter to vga) and the DVI port. Whilst the VM is up i have been able to rdp to it to confirm its up and running.
Whilst RDP'd i updated the gpu drivers to the latest listed by the vendor.
Ive also tried some of the advanced settings in the VM tab of Unraid, changing to the supported q35 2.3 which shows it supports PCI-E.
I think i have run out of ideas, if you have any tips or tricks or if there is further documentation on GPU passthrough i would appreciate that.
