Did you calibrate your monitor? If yes, what was your calibration process? What device and software did you use? I am coming from calibrating projector and plasma tvs and I do own an X-rite i1 display pro colorimeter. My software of choice is Color HCFR. Calibration is lengthy process. I play with the the X-Rite i1Profiler, which was extremely quick and painless but I won't how accurate of a job it does. It did not ask me to make any changes to contrast/brightness, colors, saturation, etc on my monitor. It seems to took a bunch of readings of the different colors and create a profile that Windows uses to adjust the graphic rendering software/hardware. I haven't done any validation to ensure how far off i1Profiler is, but I doubt it's quick profile process would result in dEs of less than 3 across the grayscale.
