I looked at several of the TN panel 22 inch screens over the weekend (Gateway FPD2275W, Sceptre x22wg-Gamer, Samsung 225BW, Westinghouse LCM-22W2, HP w22) and I have to say I wasn't happy with any of them, even after spending time tweaking & making sure they were setup correctly @ native resolution... btw the Sceptre was by far the best of the bunch & uber-cheap @ $329 (Costco) but still I wasn't thrilled.
Compared to the 20 & 21 inch models colors were washed out to my eye & there was substantial banding visable in videos ...too bad because I really like the size of the 22 inch panels, but as others have mentioned, unless its only for gaming and/or you arn't too particular about color accuracy & clarity the TN's are best avoided.
I still havn't made a final decision, but it looks like its coming down to one of the discontinued 21 inch S-PVA screens (Gateway FPD2185W or Samsung 215TW) or a big jump in price up to a 24 inch screen like the BenQ FP241W. Good news is that my 21 inch CRT is still working fine so theres no real rush.
