Does connecting the ps3 to my 720p hdtv bravia automatically make the games/movies etc appear in that resolution?

And when i buy a ps3 , are there any additional cables i need to buy not included in the package for HD?

thanks people

I think my bravia is a 720p

its a SKDL 23S2010

Is it pointless getting a ps3 without 1080p or does that not make a difference?
