Why can The 360 Games Almost All Do 1080p, yet ps3 most games are 720p?

May be...

cause it upconverts it the ps3 does native reolution no sizing

Any model of either the 360 or PS3 are capable of doing 1080p. The way they both go about it is slightly different.



Most games for either console are actually 720p native; there are a few more games for the PS3 that are 1080p native than there are for the 360.



However, the 360 has a hardware scaler built into it that every game will use, so if you set your 360 to 1080p, then every game will be sent to your TV at 1080p -- the 360's hardware is handling the conversion from 720p to 1080p.



The PS3 doesn't have a hardware scaler; it does it in software. Because it's in software, not every game will use it. As a result, some 720p games will be sent to your TV as 720p, while others will be upscaled to 1080p.



Oh, for those that say that older 360 consoles only do 1080i, that's only sort of right. You need a new 360 with an HDMI port to guarantee 1080p. Every 360 does support 1080p over the component (red/green/blue) connectors, but not every TV supports it so sometimes the TV will force you to max out at 1080i.

The 360 Elite will upscale to 1080p. All the other 360 consoles go to 1080i.



PS3 games have a native resolution of 720p. That doesn't mean they won't play in 1080p.



720p is the native resolutions for the majority of the games of both consoles. I doubt any 360 game has a native 1080p resolution since not all their consoles will go to 1080p.



Sports games tend to be 720p only since its easier to view the ball in 720p, which is why ESPN/ABC is only 720p on the TV.

There are more PS3 games which run natively in 1080p than there are 360 games.

Both consoles can upscale most games to 1080p.

The xbox 360 can do 1080i not 1080p, which is not near the ps3 which can do 1080p.
