It's just arrived and is running through VGA (ewww) on my work PC. First impressions are that it is built very well and there don't appear to be any dead or stuck pixels. Colour wise, it needs a lot of adjustment, but I'll sort that out when I get home and can run it through DVI. Also, the Dell logo is mirror like, which is a little off putting as you can see movement in it.
The glossy screen isn't particularly nice with overhead lighting, but I am sure it will be fine at home in a nicer environment. Gaming should be great.
