Spending time on GPU passthrough and seeing it evolve brought forward a topic of people running VM in passthrough with direct output to the screen attached to the GPU.

Obviously, this had me wonder if it would be possible to have this one GPU output to multiple screens directly, this card has 1 HDMI out en 3 display-port out so that would deliver a lot of screen surface (which i could use for performance graphs, monitoring etc.)

Has anyone attempted this ? Is this documented ?

Hi,

with PCIe passthrough, you attach the device to the VM.
So The VM has 100% control over this device.
So if your VM OS and driver are capable of managing multiple windows, it will work.
