My brother needs a new plasma for his place. Looking for a 50" for around $1,000, 3D not needed. Did some research and found the TC-P50ST30 which looks like a great TV and has an AR filter. One thing it doesn't have is the THX mode. I have a TC-P54G25 at my home and movies look amazing with THX on. Can the ST30 be set-up to something like the THX mode? The TV will be mostly used for gaming and some movies. Another TV I'm looking at is the TC-P50GT25 w/ THX, but it's a little over the price range.
