I know this is not a new question but I would like a clear explanation as we can read everything and its opposite arround this subject.

Basically there are 3 options:

Setup 1 :
GPU outputs 0-255
MadVr outputs 0-255
Display expects 0-255

Setup 2:
GPU outputs 16-235
MadVr outputs 16-235
Display expects 16-235

Setup 3:
GPU outputs 0-255
MadVr outputs 16-235
Display expects 16-235

Problems:
-There is no way on my UHD (10 bits) TV to select limited or full range.
- Graphic Card GTX 1070: When output is set to 2160p(4k) - RGB Full range, bitdepth is limited to 8 bits / To have 10/12 bits outptut on the GPU, I have to lower outptu level to limited range (16-235).

So what is the best setting for my own use (4k) ?

Madvr (0-255 / 10 bits) --> GPU (0-255 / 8 bits) --> Display

OR

Madvr (16-235 / 10 bits) --> GPU (16-235 / 10 bits) --> Display

OR

Madvr (0-255 / 10 bits) --> GPU (16-235 / 10 bits) --> Display

OR (other ?)

Thanks

madshi, warner306, ... others that know the answer, any idea ? thanks
