Just installed my X910BT, and I turned on my Xbox 360, and it displays okay, but I got 2 horizontal lines moving down the screen slowly. With my other chinese screen, everything was fine. Ill check the AV Cable connection in the back later, but I wanted to see if anyone else had this issue. I select AV1 under the AV Source screen. Thanks!

xbox 360 requires an enormous amount of power so maybe this has something to do with it.

have you tried other video sources to see if the screen does the same thing? maybe hook up a portable DVD player or something.
