RE: Alienware Laptop has vertical flickering pixels across the screen
It is an Alienware 18. The screen has a persistent pattern of flickering depending on the color and shade on the screen. It does not overheat and the distortion is constant, unless I am viewing a solid color with a certain shade. When I connect it to an external monitor it does not have distortion (the monitor). I checked the PSA Diagnostics and it showed certain colored bars with the distortion. The LCD BIST did not show any apparent distortion however. The diagnostics did not show any errors and there was a very slight distortion around the letters in the BIOS. The system is not under warranty.
