I don't know where to begin. I just bought a Samsung 50" HL T5075S at a Great Kickass Deal (Good Timing I Had) mostly for my Xbox 360 and Movies after I bought it I relize that it's a 720p I don't know the differance between 720p or 1080i or 1080p All I know is I'll be sitting 9Ft away from the TV. What I want to know is. 1. How close are you suppose to sit in front of a Big Screen. 2. Will there be much of a Differance on 360 or Movies 720p or 1080? 3. Is Samsung a Good Tv for Quality Pictures
