AMD GPU Color

[RobertoStephens]

Hello,

So, it appears that the AMD GPU driver (with dc enabled) does not allow to choose between the full and limited (16-235) color range, but chooses automatically. I dug into the source code but it's quite convoluted, does anyone know the algorithm that it uses to choose?

For a question this specialized you might have more luck emailing the amd-gfx mailing list on FDO.

IIRC, it's based on something in the EDID, but it's been a while since I looked at it.
