I've been having terrible calibration problems with the screen on my Thinkpad. In calibrated software, blues are purple, and everything is garish. Otherwise everything looks muddy and washed out. I've pretty much given up on trying to use it for anything other than making sure the photos are framed properly.
I would really like to get a nice midrange LCD that I can use for photo editing. I don't particularly care about having a huge screen, so 20-22" would be fine. Something that will calibrate well (S-IPS panel), preferably no more than $500-600. I live in Canada, so it would be good if I could buy it here, but I'm open to any suggestions.
I've been looking at Dells, but almost all of their smaller LCDs use TN panels now for the low price point. The 2408WFP has an IPS panel that's supposed to be quite nice, but I've read bad things about input lag. I also looked at the higher-end NEC LCDs, but I'm not ready to spend $1200+ on an LCD just yet.
