vGPU + physical display?

[drmatt]

Hello, I read that vGPU is now officially supported in PVE, which is great news.

What happens to hardware display outputs (such as HDMI and DisplayPort) when vGPU is enabled?

I currently pass through my entire GPU to one of my VMs. This allows the VM to serve as a head for natively displaying a desktop on dual monitors via physical DisplayPort connections on the host machine.

I'm wondering whether something similar is possible with vGPU enabled. Can I designate one VM as "owning" the host's hardware display ports so that it can outputs its desktop natively to monitors without using remote desktop software? Or are those ports just dead?

you can't use physical output. vgpu is mostly use for gpu compute (ai, machine learning,...). or you need a fast network display protocol like for cloud gaming.

I see, so turning on vGPU effectively disables the output ports on the card. In that case maybe I'll try passing through the integrated graphics instead and using the outputs from the motherboard to drive the displays. Thank you!
