I have a Nvidia GTX 980 Ti hooked up using HDMI 2.0 to a reciever and HDR projector, but can only get RGB full range 12bpc at 30hz 3840x2160 or less, and at 30hz the input lag drives me nuts. I have tried everything i can think of to get it to a higher refresh rate. I dont even need the 12bcp, i would be fine with 10bpc but i can only get 10bpc to work with 4:2:2 enabled and text looks like crap.
anyone have any ideas to get 3840x2160 30+hz 10bpc RGB Full range to output from the thing?

HDMI 2.0 can only do 3840x2160 @ 60 Hz at 8 bpc with RGB 4:4:4. 10/12 bpc would require YCbCr 4:2:2.

yeah but what if i drop the refresh rate to something just above 30hz
