I bought a new laptop a week ago, A 15.6 in Lenovo Y50 Touch, and its been great except that yesterday I noticed a vertical black line appear right down the center of my screen. The line is only visible when there's no programs blocking it, so only when my laptop is just showing my background can I see the line. When on the web or playing a game or anything else, the line is not there. It's not the background itself, I have tried that
Added (1). Black line*
