They are good monitors and I'm happy like a hippo with them.
The middle ones are older model. 2311 while the two side ones are the new model 2312HM, the difference being that new models are with LED backlight (and couple things dropped from the menus to save costs) while old ones have cathode back-lights. All of them have displayport input and very solid stands that allow you to use them in portrait. Bezels are about 20 mm per screen though so if you put them side by side in portrait for eyefinity/surround you will end up with approx 40 mm gaps between displays. As far as "input lag" goes I do not feel any - even in rather fast paced shooters like, for example, Tribes Acend. Dunno perhaps the 120 Hz crowd is more sensitive in this regard.
However, if I would be starting to assemble my screen wall today I would go with the 27'' Koreans as they are only about 30% more expensive but have about twice the number of pixels. Some of them are also overclockable so you can push the refresh rate up to ~90 Hz or so so overall very good value. You ofc lose out in warranty terms when compared to UltraSharps. Ultrasharps have zero defective pixel policy which is a bit unusal (by ISO standards you can have up to 5 defective pixels on 1080p screen and most brands follow ISO standard in their warranty terms).
