Currently I have a RTX 3090, a LG C9 65″ plugged in directly to HDMI, and two LG CX 48″ connected via CAC-1085 and using their HDMI 2.1 cables.
If I stay on driver version 456.38 I can get “Full” Output dynamic range and select “RGB” for Output Color Format. Using any other driver version and I am limited to the “limited” Output Dynamic Range and I cannot select “RGB” as the Output color format.
I’m not sure what to do at this point. Both adapters have the same problem on either TV. I’d like to use all three monitors at the same time with the latest driver revision. All TV’s are set to HDMI Ultra HD Deep Color and have all the same settings otherwise.
