Not all monitors by the same brand have the same underlying qualities. Take, for instance, the Dell Ultrasharp u2312hm and the Dell Ultrasharp whatevertheir30"modelnameis.
Both are IPS. Both are labeled "Ultrasharp". Seemingly the only difference would be size and resolution. Not so. The u2312hm is significantly more responsive when gaming, with low input lag and excellent motion performance. The 30" version's motion performance is ok, but its input lag is something awful. So the 23" monitor is a great gaming monitor. The 30" monitor - not so much. None of this is obvious when looking at advertised stats.
So don't go looking at Dells of various sizes/product numbers and think they're going perform the same other than size/resolution. You really have to look them up at a professional review site (TFT Central, Prad.de) to see if they're really going to work for your purpose.
Another example:
Benq xl2410 - terrible 120hz monitor because 120hz is all about perceiving smooth motion when fast-moving objects in a game whiz by. Yet the xl2410 has bad motion blur. But the xl2420 is one of the best 120hz monitors because it fixed that problem.
