I haven't noticed it on my 360, but on my new Playstation 3, I've noticed vertical stripes running up the screen. They're faint, same sized(roughly 1" in width), and evenly spaced(maybe every 2.5"). They seem to be more predominant in the more muted colors, and when the game is in motion. It looks like my screen is striped with lines that are just a few shades darker. I don't know how to explain it. I've also only noticed it in 720p, specifically on the DMC4 demo, and Burnout Paradise. Ps3 is hooked up via hdmi, btw. Any thoughts?
