Hello! > Yes, that is true. My ccmx matrix and the matrix from the list for > "Spyder3 + HP LP2475w" combination are different. Completely different. What instrument did you use to create your own matrix? Did you validated accuracy of your Spyder/matrix combo with this instrument? If so, what dE values did you achieved? > P.S. BTW my Spyder3 works fine in Quato iColor Display when setting "Wide > Gamut S-IPS (generic)" colorimeter correction option. (I compared it with > i1Pro.) Interesting. What was the results of validation? I assume that you've calibrated and profiled your monitor with iColor/Spyder and then validated this calibration/profiling using i1Pro. Maybe you're lucky and your Spyder3 have small reading variations from generic (mean) values, but I'm afraid it's not the case for most Spyders. -- Best regards, Darek
