[QUOTE="HomeY, post: 476251, member: 68365"] I was doing that assumption the first time also, but why does it give correct blacklevels [u]everywhere[/u] except inside MP? [b]** EDIT **[/b] Well, another fresh install of Vista + MediaPortal today. @Dr Tone: Could you please test something for me. I was playing with the -28 brightness settings in ATI CCC and i noticed a difference between the Color settings and the AVIVO color settings!

Since you told me you pulled it down to -28 all over, i'm curious if you also have that difference. The above difference in settings between ATI Color and AVIVO Color can be very interesting. ATI Color -32 = reference black AVIVO Color -16 = reference black But the contrast is also not correct ATI Contrast +32 = reference white AVIVO Contrast +16 = reference white And 16 levels difference can be the difference between 16-235 or 0-255. Coincidence?? Another strange thing i've noticed is that when i output Limited RGB from ATI CCC and set my tv input to 'Auto' that it gives the same picture as when i set it to Full RGB input.
