[PUREBAY2200]

So after lookin for my 2 big tv I landed on a 55" led LCD 1080p 120 hz insignia. My buddy has one and it was awsome to view. So I went to best buy and talked to the fellas there. They all agreed that it was a great tv and the sale price was nice also.
So I bought it tonite....
Here is my issue.
When I start up my ps3 the screen says 1080 p and it's crystal clear.... Then when the intro to ncaa 2011 starts the screen displays a 720p image and the clarity goes away....
Also the surround sound is supper static......

My new LG does not do this.....
So any ideas??
