I'm personally quite fine with DELL's but I have also heard that some people do not like the matte finish on these DELL's. If you have a store somewhere nearby where you could actually take a look at them yourself it might ease up the decision process for you. TBH I dont see any "graininess" on mine.
I have three DELL U2311H's (older model, has cathodes instead of LEDS for backlight) and two U2312HM's (newer model, some features dropped, LED's for backlight a bit cheaper and takes half the power) and I'm personally quite happy with them. Using them in 5x1 portrait Eyefinity at 5400x1920 resolution. Started small - first got couple of them and later on added monitors when I was able to afford the additional displays. Thats why I have three of the "old" model and two of the "new" model. Took me approx a year to get altogether five of them.
As far as the second display you linked goes - in my opinion its a way overpriced although its probably good display. At that price range, however, you should be starting to think about 2560x1440 resolution in my opinion. Or throw in extra 50$ and get 3x U2312HM's for eyefinity for 3240x1920 16:10 IPS screen. If you can stand their matte finish and bezels that is.
Some people seem to love 120 Hz screeens over anything else. And to be honest, TN screen is fine as long as you use it strictly in landscape orientation. I personally are a bit biased and prefer IPS over 120 Hz if I have to pick between the two.
Edit: let me throw up two heavily zoomed in photos of my display - in case it helps you decide either way. This is DELL U2312HM, Pentax K-x with 200 mm macro lens, 6 MP best quality jpg.
Wonder why my pictures are not showing up ?Edited by Carniflex - 3/2/12 at 4:47am
