To reduce possible errors I detached my second monitor. I also deinstalled all software which could cause trouble regarding CMS (like AMD Catalyst software or the Colormunki Display Software). By purpose my HW is quite similar to a Mac -> So it is possible to run Mac OSX 10.8 on my machine. Maybe it is a problem with the card as it is similar to the cards in a Mac OSX machine?!? > > Does the above (say using sRGB and ProPhoto RGB profiles) reveal big differences ? Hmmm... Maybe I have overlooked one of the many options in this Argyllcms ?!? What sRGB and ProPhoto RGB are you refering to? Is there a option where I have to choose "calibrate for white gamut" or where I should choose something different than sRRG? Can I choose the target color space? Is "sRGB" a default for some value in Aegylllcms? Should I change the mode of colormunki from LCD (generic) to something different (e.g. wide gamut)?
