LCDs really cannot be calibrated, except for overall brightness. They have
a fixed gamma and color temperature, so changing those just reduces the
number of possible colors and grays it can display. That's why LCDs are so
poor for graphics work. Only a few high-end models made for this kind of
work really can be properly calibrated, because they use internal 12-bit
lookup tables. My NEC PA241W does this, but only with NEC's calibration
software and colorimeter (you can use other colorimeters, but every review
I have seen got better results with the NEC one, which is made for them by
X-Rite). Plus, it has a wide gamut that covers most of the Adobe RGB color
space.
