PS2 can do 480 p in some games (full list http://en.wikipedia.org/wiki/List_of_PlayStation_2_games_with_HD_support ), but no true HD ( 720p, 1080 p).
You got to plugg the component cable, (which you can also use in PS3), activate the y pb pr option in ps2 menu and choose progressive scan in game menu.
I must tell you, a game like God of war 2 in 480p, is almost a PS3 game!!
