I use the gretag macbeth eye one display2 calibration puck to calibrate my Eizo CG19 screen. Quite happy with the results, I seem to get a good profile. In the gretag software I use the easy option rather than the advanced mode as I have never worked out how to control the individual r g b values on the monitor. Is it ok to use the easy mode or should I be using the advanced mode and if so how?
