i have black dots all over my screen. Looks like a map and then a few smudged blue marks and lines. Just suddenly appeared. Never notice because i use a docking station most of the time. Please help

Hi,

Does lines and marks changes when you move your screen lid? If yes, then it's monitor cable fault.
Does it appear when laptop is turned on from cold start?
