"A man with one clock knows what time it is. A man with two clocks is never sure." Let's amend that... "A man with one display knows what color it is. A man with two displays is never sure." I've recently upgraded from a 1st generation MacBook to the 15" Unibody Macbook Pro and I'm having a great deal of trouble adjusting to the difference between the LED backlit internal display, and my Samsung 22" external monitor. I've probably spent about 8 man-hours going through the display calibrator, and through SuperCal, on both devices, and I can't seem to get a consistent color between both displays. Am I doomed to madness? Will I have to spend money on either a hardware calibration device, or on an LED backlit external monitor? Has anyone else solved this?
