Help me with my off centered Vizio 32 inch LCD please.  

I recently purchased the newest Vizio LCD 32 inch and I popped in the THX disk off Star Wars. When the test came up to properly see 2 square lines around the circle, the far left off the screen crops off a good 2 inches of the box. And the right side of the screen is 2 far towards the left. I checked to make sure there was no zoom going on, and unfortunately the Vizio doesn't allow for a screen adjust like My Sammy LCD does. Any suggestions on how to center the viewing screen? :)

Pretty Please?? :D

Should I beg?? ;)
