Hello, I am new to Proxmox and have been trying to get GPU passthrough to work correctly (Using GTX 770) but to a dead end with Code 43.
I am using latest proxmox 7. I have followed https://pve.proxmox.com/wiki/Pci_passthrough and also https://www.reddit.com/r/homelab/comments/b5xpua/the_ultimate_beginners_guide_to_gpu_passthrough/

I also wanted to be able to plus HDMI directly to a monitor, currently I get nothing from the VM, is this possible? Do I have to pick between RDP or HDMI plugged in?

My last option is to patch the bios, but I am unable to find a tool for this that works with my GPU. Here is my config

Update: Not sure what exactly solved it, but I struggled for a week. This is a new computer so I update the bios and found another setting related to pci-e passthrough that wasn't there or didn't notice. Finally went from code 43 to 35, then update drivers again (after uninstalling and removing gpu completely).
