Currently have a Samsung 226BW Samsung, TN for general use and an IBM T221, which I am squinting to look at, its 22" and native resolution is 3840x2400 (not a typo),
http://www.pcpro.co.uk/reviews/monitors/63390/ibm-t221it has quite a few duff pixels too.
Want to spend about £700. Been told to look at the Apple LED one, but it won't work with my gear and gets a bad rap from Pro Photo people for the sickly gloss and inconsistencies in the LED backlighting. Dell 2709W seems to be popular, can't stretch to a 30" !!!!
