Colour calibration software and tools for LCD panels has been commonplace for about the past year or so. The "Spyder" is the best known to the masses, but there are oher equally/more capable products out there as well. I have/use the Monaco EZColor/Optix combo with both my 1600x1200 laptop LCD, and the Eizo FX-E8 main desktop CRT here.
