upscaling doesnt bring more detail.

Upscaling will not bring more detail. Say you have 1 brown pixel at a smaller resolution, when displayed on a tv at a higher resolution, say at 4 times the size. Without upscaling, this one pixel would then need to be a brown 4x4 area at the higher resolution. Upscaling would use the neighboring pixels to make a guess at what colors to fill in that 4x4 area instead of making them all brown. Most likely the guesswork is done by interpolation. Upscaling is not an attempt to bring more detail(that is impossible) .

Yes, over HDMI and VGA.

It doesn't over component. There's actually a handy little chart somewhere on xbox.com that shows all the possible resolution combinations.

 

That is weird because when I put a DVD on my (composite 1080i connected) 360, the screen swith to 576p mode (??).

 

Component you mean right?

HDMI is required for 720p-1080i.

Component can upscale to 480p or 576p in your case.

 

Yes sorry (oops )



 

Evan Wells (Uncharted 2): I think the differences that you see between any two games has much more to do with the developer than whether it’s on the Xbox or PS3.

@Sardauk

Don't let it happen again.



iPhone = Great gaming device. Don't agree? Who cares, because you're wrong.

Currently playing:

Final Fantasy VI (iOS), Final Fantasy: Record Keeper (iOS) & Dragon Quest V (iOS)     

    

Got a retro room? Post it here!

Of course upscaling brings detail, and you just described how it does it!

It's not the exact same detail as in the original movie source, but it is still detail even if it's "guesswork" done by interpolation.
