 This worked like a treat.. only thing i'm still stuck on is that Dsplayer no longer seems to be the default player.. i've checked off the box in settings but it doesnt seem to take effect.. i always have to do a play with option to select it.. any thoughts?  EDIT:  i guess i messed with video player merits.. removed that and it now works.. golden..

One other question/confirmation.. I should only be seeing RGB 8bit FULL in nvidia settings with the samsung q6f series TV (10bit) correct?  Should i have madvr settings at 10bit or auto.. i think 10bit?   

I would configure things using these rules: https://forum.kodi.tv/showthread.php?tid...pid2739438

The only issue is that current Nvidia drivers won't switch correctly from 8-bit RGB at 60 Hz to 12-bit RGB at 24 Hz after a reboot. You might have to set everything to 8-bit. madVR rounds everything with dithering at output, so you aren't likely to notice the difference with your eyes. 10-bits at the display isn't necessary and won't involve any loss in image quality. When it comes to the display, the issue of 10-bit color is misunderstood. 

If you are going to stick with DSPlayer, you might as well make a couple of profiles in madVR that will work with your display and graphics card.

If you want the image to be sharper, try checking sharpen edges or any of the other combination of shaders under image enhancements for the 4K UHD profile (requires another profile group) or anything under upscaling refinement for the 1080p profile. 

This is awesome, thanks for outlining this, i didnt find anything this detailed for now.. i take it the custom profiles will have advantages for each format 1080 vs 4k.. ill give this a shot and see how it looks.

Is the control J info that displays enough of an indicator if it kicks into 10 or 12bit mode despite being at 8bit.. is it ok to leave the madvr bit option to auto in any case here given all this?
