Am I way too late for this? I've always really liked Dell's Ultrasharp line for stuff like that. I've had a 2408WFP for a couple years, and it's great, and the model that replaced it (U2410, I think) is supposed to be similar or slightly better. There are some other IPS and PVA/MVA (i.e. anything but TN) displays that are supposed to be pretty good in the same price range, too, but I forget which models specifically.
Pretty much the only way to get a 1920x1200 instead of 1920x1080 screen these days is to step up to the better-than-TN panels, which will cost more, but they look much better. The idea that you absolutely need a 2ms response time is largely a bunch of crap, and the way they measure and report it is pretty hazy anyway. The only way to get it that low is with a TN panel, which sucks for other image quality-related reasons, and I've never noticed this monitor ghosting or lagging at all while playing games. The dramatically improved color gamut and viewing angle are well worth it for me anyway.
