[QUOTE="rivera, post: 556727, member: 85161"] 1. I do not have such a choice in Nvidia Control Panel :( 2. So, you think that in case of "YCbCr444" I will see a pure black? As I understood, standart VMR9 renderer converts YCbCr420 (used in video content) to RGB. By using ffdshow (or CoreAVC - but for H264 only) I can convert YCbCr->RGB as a part of post-processing. So, this convert seems to be an obligatory - whether it is done by renderer or by ffdshow (or CoreAVC). If video driver outputs YCbCr into display that means that RGB agan will be back-converted to YCbCr - with accumulated errors [/QUOTE]
