[QUOTE="HomeY, post: 474189, member: 68365"] But if ATI messed up with their drivers, why do i get correct blacklevels outside mediaportal with both PowerDVD and MPC-HC when ATI output is set to limited RGB and TV input is also set to limited RGB? And i just can't understand why MPC-HC needs to be set to 0-255. If we go back to the basics and look at the material (DVD, BluRay, etc.) all those sources are encodec in YCbCr 4:4:4 (which is kinda simular to limited RGB since it uses Video Levels instead of PC Levels). So outputting FULL RGB (0-255) would expand the video levels off the source and create grey blacks. Off course you want the video as untouched as possible to keep the best Picture Quality which would result in outputting Limited RGB from the videocard and inputting limited RGB to the TV. Then again.... My TV is ISF Calibrated with the 9.5 drivers with output of ATI and input of TV set to limited RGB.
