I've noticed that on certain newer games, I've had graphical glitches where certain items, like objects or environmental pieces, have a very obnoxious glitch where there are purple and green boxes all over the object. Example are my weapon sights in Battlefield 3, my weapons in Elder Scrolls 5, and a large amount of objects in Dragon's Dogma. I was considering this was an issue with the cable, as I'm using my default HD/AV component cable on my Xbox 360 Elite (Large, black model, 50gb or so.) This glitch is on on HDTV at 1080p, 1080i, 720p, 480p, and even in standard TV setting. Would I need an HDMI cable to fix this issue? I noticed on somebodies XBox 360 Slim with an HDMI cable this glitch wasn't present, and on another XBox 360 Slim with HD/AV cables it IS present.
