Intec lcd 5 inch screen has a wvy picture, and messed up colors

[mekast]

I bought an Intec 5 inch moniter for my xbox, and when i plug the screen into my xbox, i can see the picture, but it is really wavy, and the color is very bright and distorted. I've hooked this up to my computer using s-video, and the picture was still wavy, does anyone know whats wrong with my lcd screen? or how i can fix it?
