Use profiles for each content and follow the settings in my guide. A general use profile won't work well for everything. For example, you should be able to use higher settings for chroma upscaling when playing 4K content, but will want to turn this down and focus on luma doubling for any resolution below 2160p. No upscaling is used at 4K, so this setting is irrelevant.

And use different settings in the GPU for different refresh rates if possible. Using 4:2:0 means the chroma upscaling setting in madVR won't do anything, as it will be erased by the GPU before reaching the display. In this case, you could set chroma upscaling to Bilinear and not notice the difference. The desktop should be 8-bit RGB at 60Hz. Any refresh rate below 30Hz should be 10-bit RGB. Then you have the full RGB 4:4:4 signal (with chroma upscaling) during video playback being sent to the display.

And the choice of hardware decoder won't matter at all to madVR. There is no performance improvements. Two completely different parts of the GPU are being used. And if you aren't using native D3D11 decoding, then copy-back is being used anyways, so there is no difference from regular copy-back. With that said, just use D3D11. It is the newest decoder.

Lastly, set calibration to DCI-P3 as no current display can do BT.2020. All are DCI-P3.
