[Resolved] [No Display] GPU passthrough for EVGA 1080 TI, moved to secondary slot

February 23, 20215 yr

I followed this guide for HOW TO PASS THROUGH AN NVIDIA GPU AS PRIMARY OR ONLY GPU IN UNRAID.

Everything appears to be "working" but I can't RDP into the machine and my monitor that is connected to the 1080TI graphics card never turns on. Any ideas?

I extracted my ROM BIOs and then setup my VM profile to utilize it as follows:
