1920x1200 usable monitor

[weird_dave]

I'm trying to find a monitor that can do 1920x1200 (23"+), and doesn't suffer vertical brightness gradient when viewed from the middle (I think this rules out TN panels, you seem to need your eyelevel to be above the top of the monitor). It also need to be suitable for gaming.
I also use an xbox360, so dual inputs required (1 VGA, 1 DVI) and 1:1 mapping.
Any suggestions are greatly appreciated, I've been looking for weeks now for something decent.

We have 4 of the 2407 at work, and I don't like them. plain colours (including white) seem dithered or mottled. Admittedly they are using VGA, but I've seen panles which don't do this (unfortunately they were TN....).
Both the Dell and the HP are also quite expensive, I was hoping to find something around £300. I would wait for prices to come down, but my current 21" CRT is going wrong
