Hi,


I'm having calibration difficulties with my Radeon HD 4670. I'm trying to calibrate brightness / contrast using the S&M blu-ray disc and here is the problem:


The levels are always being expanded. Only if I adjust CCC to brightness +16 and contrast 86 I get the full range of levels without expansion. Thing is that I don't want to make adjustments at the driver level.


Moreover, even if I fix the issue through the CCC then I get banding.


So, the way things are right now I can get an untouched full range video but with banding, or get an expanded video, maybe without banding (I have yet to check it).


Is there a way to get an unexpanded video while calibrating to full range without banding ?


Here is the setup:


Radeon HD 4670

ATi Catalyst 10.2

WIndows 7 32bit


Arcsoft TMT3

it is different for everyone. The best option for me with no banding, wtw and btb is ycbcr 4:2:2 with dynamic range set to full.
