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

That depends on what timings the projector will accept. If it will accept arbitrary timings, then all you need to do is keep the pixel clock below 480 MHz for 10 bpc and 400 MHz for 12 bpc. There's also the issue that audio requires some horizontal blanking, so that might reduce what you can get with audio.

how do i go about trying that? i believe its fairly open to timings, i have tried fiddling with them before.

What does CRU show? Export a file and post it here.

Something is weird about your GPU because the 1050 Ti should support 1920x1080 @ 144 Hz and 165 Hz just fine with HDMI. Is this a laptop or desktop?

Just add a detailed resolution for 3840x2160 and try refresh rates that keep the pixel clock below those limits.

yes, before reset, both of em just work fine, but i dont know why now, this is a laptop

I have laptop hp zbook 17 g3 FHD 60HZ
nvidia quadro m5000m 8g
I7 6820hq
When I go to overclock refresh rate I got a black and white screen and the screen not and mixed colors
I tested all settings
I need a help
Please
And thanks in advance

If the laptop has an Intel CPU, then the integrated Intel GPU controls the outputs and available resolutions. Intel GPUs without HDMI 2.0 only support up to 300.99 MHz pixel clock. "Native PC" or "Exact" timing will keep 1680x1080 @ 144 Hz under the limit.

wait what, it is true, somehow its work if under 300 mhz, i tried 1920x1080 130hz

also is there any way to make the nvidia gpu control the outputs, sorry if im being dumb, because i somehow can above 300mhz before reset this laptop
