There have been a few questions relating to the scaling issues on PS3 games, such as the one below:
“Could you try and get info from Sony about the solution to the scaling issues on PS3 games? It seems a lot of people on the net are having trouble with their PS3 due to their TVs being only capable of 480i, 480p, and 1080i.”
“Since the PS3 can’t scale games to a certain resolution, these people can’t enjoy native 720p games being scaled to their TV’s resolution, and instead the PS3 boots the game into 480p. If you could get any info on how this is going to be fixed, or when, that would be greatly appreciated.
Here’s what PlayStation had to say in response:
720p is a higher resolution than 1080i. However, there are limited TVs that can output 1080i rather than 720p, and the HD Ready logo in Europe guarantees the TV is capable of 1080i and 720p
Resolution quality from top to bottom is:
576p (480p for the US)
576i (480i for the US)
Therefore, if you tell the PS3 that you can’t do 1080i, the system has to drop to the standard definition resolution of 480p, because the PS3 won’t scale the Blu-ray video output up, and the source Blu-ray material will be at 1080 for high definition.
However, as the PS3 firmware can be updated, this is something that could be included in a later revision and unlike the recent 360 update, the PS3 can run true 1080p, as HDMI is standard on both 20 & 60gb models. What resolution the game is capable of is up to the game developers - all the way up to 1080p.
