Displayport to HDMI 2.1 adapters no longer working correctly on 6.4.12 works on 6.4.11
Brief summary of the problem:
I am using a DisplayPort to HDMI 2.1 adapter (specifically this one ) to workaround #1417 on Kernel versions before 6.4.12 I was able to successfully get 4k 120 full rgb with VRR enabled and working, however on 6.4.12 I get either a no signal error message on my tv, an invalid format error, or just a black screen.
