Minimal vertical marks appearing across a laptop display
Minimal vertical marks appearing across a laptop display
I understand there are many concerns about this problem, but I looked everywhere and didn’t find anyone else experiencing the same thing. It seems to be with my DELL Inspiron 15 7559 from 2016. Recently, my screen displayed thin, horizontal lines covering the entire display—both in height and width. The lines aren’t a single color; they appear as uneven, half-dark and half-light. I’m unsure what’s causing them. They resemble scan lines from an old CRT TV, but not black or green. They start after a few minutes of use and vanish on their own, reappearing randomly. Occasionally, when the screen goes black, these lines seem to disappear temporarily before reappearing as the black screen fades and a wallpaper appears. This is my first time posting here, so I’ll try attaching a photo or video for clarity. They don’t show up in screenshots. VID_20240311_195421 (1).mp4
