Thanks Graeme, actually I've pasted and discussed the settings I used and the results I got several times. I'm using dispcalGUI because it's easier to launch the process in a few clicks. As written before, the readings are different right before the start of calibration: white level, white point, black level, RGB slider values… all very different. Moreover, right after the profile creation every verify returns bad average dE. In the end I already tried tens of combinations, I'm not a complete newbie. 😄 It could be a software problem too, for what it seems.
