I just got a refurbished 30" and I don't know if it is OK?? Could you help me?? Do you calibrate your monitors? I want to know what the Native kelvin is on yours? When I calibrate using an eye1 D2 set to 6500K, 2.2 gamma, 120 LUM.s I have a bit of trouble getting a good calibration. When I do get a good one, and compare an album that was printed with the original files they have a reddish tint, skin colors. it comes back with the 6500K that I entered. Now if I enter Native temp into the program and run the calibration it It comes back saying white point, temp, is 11K .. that's nuts. Could my screen be out of wack? I need to know because I shoot weddings and need good calibration that I can trust. I have been on the phone with apple and would you believe they cannot tell what the native temp is supposed to be on the monitor.
