I ran fiber optic HDMI from my office to my living room for 4K120 HDR+VRR couch gaming with no added latency or loss in quality. Works great. My LG C1 even supports FreeSync so VRR even works, but I have to route the HDMI directly to the TV. My receiver does not support FreeSync and only supports HDMI VRR. Presumably with this patch I will be able to run HDMI 2.1 VRR through my receiver and not have to treat my desktop as a special input.

It's just nice when technology is not hampered by nonsense.
