anyways, that display looks very much similar to what I have except that mine has silver bezel. I think you can go for it. But order it online as support can be a problem if you buy from local hardware dealer.
and if you can pay 3k extra, I think you can go for the BenQ 22" display that support FullHD display. but you need a good Graphics card to drive that display (while playing games and watching HD movies)
You better get it from Dell. Check with your dealer if you he can take care of warranty issues with the monitor. It's not that you face problem but you need to be in a better position when any problem comes up.
