I originally made this post here: https://forum.proxmox.com/threads/gpu-passthrough-help.26989/
After searching the VFIO mail list I came across these two posts:
To solve the black screen / BSOD after installing the AMD video drivers they attach a ioh3420 pci-express root hub to the VM and then assign the video card to it.

Is this possible to do with proxmox and if so, how do I do it?
