If your TV doesn't support a specific resolution, expect to go low-res.
Gamers who own older HD sets that feature only 480i, 480p, and 1080i resolution input capabilities will have to settle for the display quality being downsized as the game boots in its 480p mode rather than upscaling the image from its more desirable 720p mode to the TV's 1080i.
The PlayStation 3's competitor, Microsoft's Xbox 360, does upscale 720p games to 1080i if the HD set supports the latter resolution but not the in-between and commonly-employed 720p resolution.
