nVidia HDMI bug Display Unknown-1

Hi - Might be a dumb question. I have a spare Frankenstein box that I am playing around with and put CachyOS on it. I recently had to take out a cursed 1080ti GPU and put in an OLD NVIDIA GPU I had laying around. Ever since I put in that older GPU my Display shows up as unknown-1. I have my main rig hooked up to the same display through the Display Port and it identifies it fine. Does anyone know how to fix this, and if so, could give me some step by step commands like I am an idiot to fix it? Thanks!!

GPU 2 is the older card
