 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.

Under scaling algorithms, select create profile group.

Check all items and name the new profile group Scaling.

Use add profile to create two profiles: 1080p and 4K UHD.

Copy and paste the code below into Scaling:

if (srcWidth > 1920) "4K UHD"
else if (srcWidth <= 1920) and (srcHeight > 1080) "4K UHD"

else if (srcWidth > 1280) and (srcWidth <= 1920) "1080p"
else if (srcWidth <= 1280) and ((srcHeight > 720) and (srcHeight <= 1080)) "1080p"

You should get a green check mark if your profiles are named correctly.

4K UHD:

• Chroma: NGU Anti-Alias (high)
  
• Downscaling: SSIM 1D 100% + LL + AR
  
• Image upscaling: Jinc + AR
  
• Image doubling: Off
  
• Upscaling refinement: Off
  
• Artifact removal - Debanding: Off
  
• Artifact removal - Deringing: Off
  
• Artifact removal - Deblocking: Off
  
• Artifact removal - Denoising: Off
  
• Image enhancements: Off
  
• Dithering: Error Diffusion 2
  

1080p:

• Chroma: NGU Anti-Alias (low)
  
• Downscaling: SSIM 1D 100% + LL + AR
  
• Image upscaling: Off
  
• Image doubling: NGU Sharp
  
• <-- Luma doubling: very high
  
• <-- Luma quadrupling: let madVR decide (direct quadruple - NGU Sharp (very high))
  
• <-- Chroma: let madVR decide (NGU medium)
  
• <-- Doubling: let madVR decide (scaling factor 1.2x (or bigger))
  
• <-- Quadrupling: let madVR decide (scaling factor 2.4x (or bigger))
  
• <-- Upscaling algo: let madVR decide (Jinc + AR)
  
• <-- Downscaling algo: let madVR decide (SSIM 1D 100% + LL + AR)
  
• Upscaling refinement: Off
  
• Artifact removal - Debanding: medium/medium
  
• Artifact removal - Deringing: Off
  
• Artifact removal - Deblocking: Off
  
• Artifact removal - Denoising: Off
  
• Image enhancements: Off
  
• Dithering: Error Diffusion 2
  

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.
