PlayStation 3 Lacks Upscaler to 1080i
Reports are flooding in that PlayStation 3 is unable to upscale its video output, leaving many with older HDTV's, including those from Sony, out in the cold of standard definition.
Early word came in from the NeoGAF forums, where users with 1080i TV sets tried to run Resistance: Fall of Man, only to find that the game would force a switch down to 480p. The reason behind this is that Resistance runs at a native 720p resolution. If the game is played on a television that does not support 720p, which applies to many older HDTV models, then instead of upscaling to 1080i to retain its HD status, it downscales to 480p, losing much graphical fidelity.
