> I'm going to write an article in Italian on monitor calibration (HP LP2475w) with Spyder3 and Argyll. Be careful with that! LP2475w is a wide gamut display but Spyder 3 is not a WCG filtered colorimeter and ArgyllCMS doesn't support correction matrices. You have to feel that something is wrong after the calibration. It is the white balance. (You can set it better with your eyes.) And you should notice that the profile is also broken because the primary color coordinates are false numbers. You will need a spectrophotometer or the iColor software with a unique correction matrix. This should be a commonly known problem!
