I'm unsure if my new TV does 4:4:4 on 24Hz as well, they only stated that it does 8bit 4:4:4 at 50/60Hz with PC mode on and UHD color on.

Should i thus decrease native bitdepth to -> 8bit, and disable DX11 10bit?

The Blurays i have are encoded in 4:2:0 and probably 8bit color, if i understood correctly, MadVR will upscale it to 4:4:4 RGB & 10bit?

4:4:4 is a description of chroma subsampling using the Y'CbCr color space. madVR will output as RGB, which is 4:4:4 (or equivalent). Some TVs will want to convert the RGB output back to Y'CbCr. This could mean down-converting to 4:2:2 or 4:4:4. This would remain true regardless of the bit depth (8 or 10-bit).

In either case, this should not make much of a difference. There is a 4:4:4 test image in the Image Scaling section of the set-up guide if you are curious what your TV does to the signal. But 10-bit RGB is, of course, possible with any TV.

Doesn't
4:2:0 = 8 Bits
4:2:2 = 10 Bits
4:4:4 = 12 Bits?

RGB is measured in bits per channel: 8-bits per channel or 10-bits per channel.

So, RGB 4:4:4 at 10 bits would be equal to 30 bits. RGB 4:2:2 would be 20 bits.

So MadVR actually does output in HDR format without the dolby program?

What happens if the TV doesn't support 4:4:4, will the TV or the GPU be left to downgrade it to 4:2:2 or will MadVR detect it (If Nvidia control panel is set to RGB). Cause RGB is dynamic from what i understood? It doesn't need switching from 444 to 422 etc in control panel?
