I recently got a new laptop, and still had to calibrize the monitor. If you're working with graphics and photos, this is definitely something you need to consider! If you've never done it, you'll find there are many ways and options out there, some more or less confusing. Here's one of the many tools out there that'll do the job perfectly and for free for you if you're either on a Vista or XP machine, Calibrize 2.0.
Hope you'll find this helpful, too :)
