I have a LaCie electron22blue III and calibrate the monitor using my video card control software. I need to get a true calibrator but so far this has been sufficient. Since I saw the variation in the top image and not the others, I did not believe it to be a calibration issue but differences in the actual images.
What kind of calibration kit do you use? Do you use an LCD screen or regular monitor. So far, I have stayed away from LCD screens but that was 5 years ago when I got the LaCie, so I am sure things have changed siince then.
