what's the difference? I am moving into my first college dorm room in a few weeks and am looking to purchase a ~20 inch flat panel for my bedroom just to watch tv laying in bed. I want to make sure that it is high def, however, in order to play xbox 360 on it in high definition graphics. A lot of the televisions are also stating "edtv ready" or "hdtv ready" compared to just "hdtv". Can some electronic gurus help me out, or even better, point me in the right direction of a great tv for a reasonable price?
