I can vouch for the IPS panels by Dell. I have one from the previous series, the 2209WA. It's 22", 16:10 and runs at 1680x1050 (i wanted the extra vertical space for flight simming and i also wanted a low-ish resolution so that i won't need to upgrade my GPU soon).
The input lag is minimal and the only way to force ghosting through change of images is to use trackIR/freetrack and move your head left-right so fast that your neck hurts.
In other words, it's perfectly capable of displaying all those fast gaming effects like explosions and the like without any ghosting at all.
Their premium range also comes with a 3 year warranty with on-site replacement policy for the slightest pixel defect.
Many brands claim zero pixel warranty but if you look at the fine print they specify "stuck pixels are pixels stuck to white or black" or something equally silly, which means that if your stuck pixel is the wrong color you don't get a replacement. Well, not with Dell, they cover any kind of defect on the premium models.
The colours and viewing angles are no contest for TN panel monitors also. The only problem IPS panels have is that black is not as black as it should be, but the rest of the advantages really make up for it.
