Just two things. The desktop is set to 8-bits RGB at 60hz. But what about at 23hz? You are outputting from madVR at 10-bits, so you want the GPU to be set to 10-bits RGB at 23hz. Play a video and return to the GPU control panel while it is playing. Set it to 10-bits RGB. It doesn’t matter what madVR reports.

Second, you have disabled calibration controls, which means madVR defaults to BT.709. Your projector is calibrated to BT.2020, so it must convert from BT.709. You can do this in madVR by selecting this display is already calibrated and setting it to BT.2020. The gamma doesn’t matter as it’s ignored, but try and guess the gamma, too.

Some debanding at low/medium wouldn’t hurt. This won’t remove any image detail and can help with the odd Blu-ray, even if it is uncompressed.

 Thank you so much, so let me just confirm... You are saying that I should change my desktop refresh rate to 23hz, is this correct? In doing so this will enable me to select 10Bit with RGB 4:4:4? as it currently only allows me to select 8 bit RGB 4:4:4
-
I will select the "display is calibrated" and choose BT2020? Then I will choose a Gamma of 2.4? Is this also correct?

Thank you so much and would appreciate if you could confirm.. Maybe the black out screens were happening because my desktop was set to 60hz and all movies are at 23 or 24hz so it keeps changing refresh rates when playing and stopping video and possibly getting hung up in between so may actually help keeping it at 23hz? Is yours at 23 hz 10bit RGB 4:4:4? thanks..

Finally my RX560 4GB states recommended PSU 400w , I have a 300W in my HTPC but I am not powering anything other than the motherboard , the 120GB SSD Drive and the RX560 4GB .. Do you think this is sufficient power for the GPU ? May the screen black out be because of that Thanks for your help..

 For responsiveness, you want to set the desktop to 60hz. You could set it to 23hz, but Kodi will be very laggy. It could also be that refresh rates changes are causing this problem, but I wouldn't give it up until I had to. Changing refresh rates from 60hz and back again is normal for a HTPC. You can't choose 10-bits at 60hz because HDMI 2.0 doesn't support this spec. But you can choose 10-bits at 23hz (or 10-bits at 30hz for that matter).

I don't know what your gamma is, but I can guess it is 2.40. This is only important when doing HDR -> SDR conversions.

Don't know anything about the power supply. Your GPU seems to be performing alright.

Thank you so much. I will keep it at 60 hz as you say and will briefly change to 23 and 24 hz and set it at 10bit.. If you look at my previous pictures, the JVC info section is showing it at 12Bit , isn't that better? MadVR option is 10bit or above. Would appreciate if you could advise .. thanks..

Also I don't do any HDR to SDR conversion as my projector is HDR and does HDR with MadVR , should I still select the "this display is calibrated" and choose BT2020.? What will this do? Thank you
