Hi everyone. Since a few weeks I'm having this anomaly on my laptop screen (I've recreated this in paint.net):
There is a black spot (longer than a "pixel") combined with a diagonal line where the screen colors seem lighter than on the rest of the screen. The first minutes, it was just the black spot, but then a piece of the line appeared around it. The line got longer with time, until it reached the sides of the screen.
I can't find info on the internet (it is also hard to describe).
Has any of you experienced this? If yes, what is it?
