In DispcalGUI I have set the white point to 6500K Plankian locus. When I have start the calibration I have set in the OSD the white point so that the deltaE was very low (below 0.5). During calibration the white point remains OK and the 3 curves dosn't chang it, but the same white point after a profile verification after profile creation is wrong (deltaE >3). !?!At the start of the calibration I chose 6500K Plankian locus that is xy 0.3128 0.3292, why during the calibration the target white point change in xy 0.3135 0.3236?
What do you mean by "change" ? Do you mean the target has changed, or the behaviour of the display has changed ? It's not at all unusual for displays to drift over time (the time taken to make a profile for instance.) Graeme Gill.
