I've noticed this problem with my laptop screen and it really worries me.
There are leaks of luminance all over the screen. I've run in-built monitor tests and it doesn't show any problems, but visually it's very noticeable. I will add the picture here, hope it helps to recognize the issue. The question is can this problem be repaired somehow or the only solution is replacement of the screen?
Model Dell XPS 15 9560.
This would be my second screen replacement and I'm really disappointed with the quality.
