GPU passthrough error message for Nvidea control panel

[retrojp]

I have my proxmox server connected to a display port on my tv at the moment. I'm not 100% sure if this control panel message is related to the nvidea code 43 error with the driver blocking/bug i've been reading about.

In the meantime, i've ordered some dummy HDMI plugs in case it's an information issue from the tv. In the device manager, it does have the code 43 error, but i also get this message when opening the nvidea control panel. I've tried quite a few things for my old GTX760 but not ready to give up yet, although I have an amd card i could try but i'm resilient

did you try to open the control panel on the tv or via a virtual display (novnc/spice)?

Apologies, this is on a guest windows 10. I tried the dummy plugs but they never helped. I had spice off and I've been using remote desktop.

I think I've maybe spotted a silly error on my behalf. I left the motherboard bios in uefi/legacy mode, thinking that because Proxmox has been booting fine, its chosen uefi. Anyway, I removed any doubt and made sure its uefi only, proxmox still works fine, but now when I try and pass through the gpu to the windows 10 guest, proxmox crashes (I lose ssh connection, and the vm is also unreachable).

Tempted by a fresh install, but will check the logs and see if I can find anything else.
