colors are good, but default brightness is way too high. have to tweak settings to get it to a level i liked (on the monitor, dvi supports the following adjustments: brightness, red, green, and blue colors).
yes, on some monitors the backlight is way out of spec and uneven, at least on the ones manufacturered last year when everyone got one. thankfully dell has a good return policy (100% satisfaction guarentee, even 1 dead pixel u can send it back), so if you're not happy with it you can try another. backlight bleeding is an issue on most lcd's however...
my friend uses the pip, its pretty cool.. supports s-video and composite.
non native resolutions look very good
works fine in battlefield (for me) but alot of games dont support widescreen right out of teh box (check out
www.widescreengamingforum.com ). works well with DVI to my HD satellite box too
here's a comparison with the apple 20"
