[SOLVED] single GPU pass-through with multiple monitors

[unknwn]

Hi everyone,

I have a VM (mint 22.1) on my Proxmox VE9 server and were able to pass-through one of my GPUs (nvidia GT 730 - 4x HDMI), however in the VM only the 1 monitor is shown.
I've already checked the GPU on a different PC and all ports are working fine, I've also swapped every cable with every port of the GPU is also working.

Is there a way to get multiple connected monitors to be detected by the VM?

If you have made pass-through the GPU, it's dedicated to the VM.
Check the mint settings, GPU drivers on it, etc.

drivers were installed.

after some deeper digging in the mint forum I found that secure boot could be an issue.
I checked OMVF and indeed secure boot was enabled.
after disabling it all monitors were detected.
