Can anyone recommend some good software to use for computer monitor calibration? My PC has Windows Vista, and I have the Eye-One meter. Free would be nice, but I'd be willing to buy something if it's worth it. I have the iMatch software that came with the device, but I'm not so sure about it. After calibration, my grays look slightly pink. My monitor is a Samsung T220. Thanks:)

IMatch is probably the best one to use in your price range.

Argyll (argyllcms.com) is one of the most powerful software for calibrating/profiling computer monitors, printers and scanners. And it's free. It's command line software.
But free dispcalGUI (dispcalgui.hoech.net) is GUI frontend that can be used for calibrating monitors in Argyll environment.
