Would a Playstation 3 look better on Full HD ?

It is way better in Full HD. PS3 looks totally awesome in HD. If you don't play games in HD, you are missing out on a lot. Any game, let alone the exclusives, look absolutely stunning in HD.

Change your PS3 setting to 1080p and make sure your HDTV is compatible. Once that is done, enjoy... :)

yea dude itll look much better. i was playing infamous on a hd tv and though that it would probably be no different on a regular non hd tv, boy was i wrong!!! i went to my friends(who only has a standard tv) and had to use av cables, infamos looked HORRIBLE in comparison. the lightening looked more fake and the texture was no where near as superb. try it :)

Yea, The games look more beautiful on PS3 in HD,

It's so so so so so so so so much better on a 1080p HDTV!!! I played on a regular av tv and then I got an HDTV for x-mas and the picture is SUPER clear! Just make sure you have an hdmi cord

Yeah it makes a huge difference. I got HDTV for Christmas and can't ever imagine going back to sd lol

try it man simply and u tell me the difference :D btw its AWESOME specially on a big tv
