There is something to be said about Apple products. They just work! Since I couldn't afford the ACR as an external monitor, I went for the Dell 2408. (half the cost) The Dell 2408 is one heck of a difficult monitor to calibrate. Like pulling teeth each and every time. My questions is this. I finally managed to calibrate the Dell 2408 with Eye-One, but everytime I unplug this external monitor (when I need to take the Macbook Pro to the office) and plug it back in, the calibration seems to revert to a default setting. Weird and annoying! I checked the Display setting in System Preferences, and the correct one is set, just the colours are way off. And I don't want to have to recalibrate my monitor everytime I unplug te damn thing. Anyone have experience with this problem?
