I had a friend who raved about the awesomeness of the graphics on the 360. It was the best visuals he'd ever seen. He was even more impressed when I swapped out his RCA cable for an HDMI one.
LOL...K, now, i'm going to be an ass...This proves the point he could tell the differences. It just it doesn't matter to him, as he just want to enjoy the game.
Edit:
And even he did not notice that BLOPS was not running at 1080p, but at 540p.
He might not know better. But do you think he couldn't tell that resolution wasn't that high? I don't doubt you. You have more experience in field. I'm just trying to split hair.
