Hi, > that's good to hear, but rather unexpected. The puzzles are: I find one thing intressting: I needed to install the patch on my machine for Mac OSX and Win 64 Bit. Without the patch for agryllcms both OS only delivered sRGB gamut. > * where MSWin is getting the display information from to emulate sRGB ? > * under what circumstances is it color management being turned on by default in DC's ? > * why can't I see such an effect on my test system ? Sorry. I have no clue... But it seems the patch solved the problem on both OS. So it is not just a problem with MSWin and the catalyst control center driver (under MSWin) as I also had the same symptoms on Mac OSX 10.8 Alex
