HDTV suggestions.

Ok first of all I don't know if this is the right area to post this ,but it said display and figured this is the right one. I've got about 700 bucks to burn and I have been looking into the LG Tv's.
I will not be using this TV to watch TV because I don't have access to it in my room. I'll be using it about 80% of the time for my xbox360 and the other 20% for movies.

Here are some links
