Hi,

I am still relatively new to proxmox. I have a Acemagic S1 mini PC with a intel N97 CPU which has a dual HDMI port. I would like to have the possibility to have an Ubuntu VM installed in Proxmox which is capable of using the HDMI ports and a USB mouse and keyboard so that I can basically have a pc runninng 24/7 which I can access quickly along my other lxc containers and docker containers running on the same PVE host.

I have managed to pass through the gpu to the Ubuntu VM using the Proxmox web portal GUI and it works great. However I soon found out that only one of the HDMI ports work and the other one doesn't. I have searched forums and have been trying some things for the past week and ruined my configuration a few times (but I am still testing things out so not harm done), but what ever I could not get an output from the second HDMI port.

I know that both HDMI ports work because I could see the proxmox terminal mirrored on both monitors (before the VM was installed or running of course).

Does anyone have a similar experience with this and was able to resolve it? Thanks
