Hello, I received the i1 Display 2 colorimeter for the photoclub, and made a first profile. Results are strange... First, when I load the profil in iccexamin and lprof, they both say that White Point is near 12000K! But during measurements, argyll said 6700K. Second, it seems that red color is over-saturated... Here are the commands I used : $ targen -v -d3 -f200 A901HT $ dispcal -v -y c -d2,1 -m A901HT Setting up the instrument Place instrument on test window. Hit Esc, ^C or Q to give up, any other key to continue: Display type is CRT Target white = native white point Target brightness = native brightness Target gamma = 2.200000 Press 1 .. 7 1) Black level (CRT: Brightness) 2) White point (Color temperature, R,G,B, Gain) 3) White level (CRT: Contrast, LCD: Brightness) 4) Black point (R,G,B, Offset) 5) Check all 6) Continue on to calibration 7) Exit Doing some initial measurements Adjust R,G & B gain to desired white point. Press space when done.

Press space when done.
