Just a side comment, The vast majority of the IPS/PSL Monitors Panels come from just two OEMs, LG (For IPS) and Samsung (for PLS).
I'm happy with My Asus PB278Q:

Previous 3 Monitors where Samsung:
One of the Best I've owned - A Samsung 24" 1920 x1200 (Note this is a 16:10 NOT a 16: 9) and Also had a built-in TV tuner
Other two Samsungs, on a 27 In and the other a 32 In, both limited to 1920 x 1080.
The Better Dells are from benQ which are pretty good.
Phillips is not that popular here in the states.
Added: For 30 Inch look for 2560 x 1600 (This is a 16:10 panel). A 30 In 16:10 panel is larger than a 16:9 panel.
