Got BETA 8 and it works!!! > dispwin -V myProfile.icm > Verify: 'myProfile.icm' IS loaded (discrepancy 0.0%) So this means that the LUT currently loaded in video RAM is no different to the VCGT tag found inside myProfile.icm, right? So, if the two are the same, that means that the monitor is under Argyll's calibration control, and that whathever ICC profile done under that particular calibration is valid, right? I could kiss you, Graeme! Last (but not least). Any reason for the ICM file extension? As opposed to ICC? Roger Breton
