I understand what it is, but how exactly does it work? I mean from a technical standpoint.

For example, nearly all Xbox 360 games are a native 720p resolution, but when played on a 1080p TV, how is the rendered 720p image altered to fill the whole screen? I've been searching the internet for an answer to this, but for the life of me I can't find one.

Thanks for the answer. That said however, is there any positive aspects to having an upscaled 1080p image over a normal 720p image?

Okay, here's my situation. Just yesterday I bought an LG Plasma 720p HDTV for the main purpose of playing 360 games on. The reason I made this decision is because I know that 99% of the 360's games' native resolution is 720p. I also know that the general consensus is that games will ultimately look better played at 720p because at 1080p they are simply upscaled. My question is this: does an xbox 360 game with a native 720p resolution played on a 720p TV look the same as a the same game with same native origin played on a 1080p TV with the 360's options set to 720p or will one have a superior image to the other? If it helps, my TV is 50".

Any answers will be greatly appreciated.
