RPi2 Limited color range? White clipping
#11
@J_E_F_F honestly I think you are barking up the wrong tree.

Almost all videos are encoded limited range (16-235).
Almost all TV's will default to limited range (16-235). (in TV style CEA modes like 720p and 1080p).

If a fully black pixel is encoded in a video it will appear fully black on TV with a level of 16.
If a fully white pixel is encoded in a video it will appear fully white on TV with a level of 235.

You appear to be trying to display incorrect colour levels by seeking this elusive "blacker than black".
It is perfect (within one lsb) as it is. If you manage to achieve any noticeable change it will only be by making other colours wrong.
