No. It doesn't occur when you move the lid. It occurs every time I turn on the computer. It occurs on the whole runtime of the computer. I also suspect the Cable. But I arranged it 10 times with no luck. I don't suspect the CPU due that the VGA Out of the laptop will also have a problem which doesn't occur on the VGA Out.
watched your vid, (background TV audio seems "TAGALOG" ^_^) this is definitely a video card/chip problem (may be due to overheating)
