That was never an issue with the 360; Microsoft's system could upscale the image to fit your 1080i set. On the PS3 however, if your television doesn't support 720p as a resolution, you're going to have problems with games like Resistance: Fall of Man that default to 720p. You see, the PS3 can't upscale the image. What does it do? The system actually downscales the picture into 480p. So if you have a television that only does 480p and 1080i, like many older sets, many PS3 games may as well be standard definition.
As it turns out, 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. We tested this development on older HDTV sets with games designed for 720p but not 1080i—Resistance: Fall of Man, NHL 2K7, Tiger Woods PGA Tour 07, and Need for Speed Carbon. Sure enough, the system downshifted all four titles to 480p rather than moving up to 1080i. This issue came up with either a digital HD video connection (using an HDMI cord) and an analog HD video connection (using component cables.)
