Hi I found correction matrix for that display, but for Huey colorimeter. Can I calculate needed matrix for my i1 Display 2 using operations, that I described below? We have three matrices: for Huey and Asus PA246Q (matrix A), for Huey and NEC 1990SXi (matrix B), for i1Display2 and NEC 1990SXi (matrix C). Try to calculate Matrix D ( for i1Display2 and Asus PA246Q): D=(B-C)+A i.e. I calculate difference between instruments on one display model and add that difference to founded matrix A. That formula mathematically correct? 2011/10/25 János, Tóth F. <janos666@xxxxxxxxxx>: > I think this display has a very similar (if not exactly the same) LG > IPS panel as the Dell U2410, but I am not sure about the backlight. > May be my U2410 matrix is better than nothing.
