[QUOTE="evilross"] there is a difference in what a game leaves the console as as to what appears on the HDTV.
Most of the argument is bunk, as to what the game is coded in as far as texture resolution, and that code is unscaled by the GPU and leaves the console as a 720p signal. In that case, there is no difference in quality, as the GPU is sending a signal to the display device in the exact same way a PC would, regardless of the texture package selected for in-game rendering.
In the case of a game that leaves the system in a non-HD format, and is unscaled on the TV you get conversion lag. This happens when playing the PS2, or Wii on a HDTV. There is a delay that happens as the TV converts the image to the screen, most of the time it is very slight to be unnoticeable, but on some TVs it can hamper timing based games like Guitar Hero.

It's not texture resolution that's the issue but renderingresolution: how many pixels the game actually uses for its game screen before turning it over to the console's internal scaler. And as noted before, the fact the scaler got used can be seen, especially if you have a fine eye for detail.It's a blight to the current generation consoles' image, where everyone thought games would be 720p (that means a native resolution of at least 1280x720@60Hz) minimum.
Its not so much of an issue, when your talking about rendering resolution, your talking about the amount of pixels that are displayed in any given texture at any given time. Yes, it carrys over to polygons on the total render image, but thats a difference that the human eye cannot at all see at these resolutions.
The thing is that the image leaves the console at 720p, 1280x720. The HDTV does not scale the image. That is the HDTV receives a 720p signal. There is no scaling involved at the display level, so the image that the TV gets is the image you see. Some console games will be upscaled from 720p to 1080p if you run a 1080p TV and have a game that will not support the resolution, but most 360 and PS3 games are now coded to 720, and can upscale via GPU to 1080, so you get no display lag at all.
GPU upscaling is a common practice in the gaming industry, every PC game does it, to accommodate the variety of resolutions that the game can be displayed as. Its not a problem, it a matter of using the hardware effectively for the best visual fidelity possible without sacrificing framerate.
