PCI Passthrough via OVMF; No Video Output

I've been following the Official Arch Linux Guide (https://wiki.archlinux.org/title/PCI_passthrough_via_OVMF) and everything has been working exactly how it should be, but once I start the VM the Monitor connected to my GPU gets grey (Before that It was showing the MSI Logo, so it detected something was happening) but nothing more happens. I have QEMU open on the second Monitor and I can see the output on the preview but not on the actual Display. Any help would be appreciated, thanks. GPU: NVIDIA RTX 3070 Ti CPU: i9-12900k (Using the iGPU for Manjaro)
