Color optimization... That's something I've had to learn all too much about after getting my LCD and finding the colors FUBARed compared to my old Trinitron CRT. Anyway, MagicTune is
supposed to work for this purpose, but if you can't get it operational,
WiziWYG is a workable free alternative. You might also require color cards (acquirable from artstores) if you want a really good match. The best solution would involve a handheld colorimeter, but those are too expensive for casual use.
Overall, though, note that LCDs have a very hard time with properly reproducing blacks and with creating very similar colors right next to each other (such as gradients). You won't get something perfect out of color optimization, but it'll at least be usable compared to out-of-the-box.
