My wife has an XPS 13 2-in-1. It has a screen issue that I can't diagnose, nor fix. See pic. The bottom 80% of the screen has very small horizontal lines running side to side, that seem to slightly flicker. The top couple inches are normal.
I don't believe it's software. Drivers are updated, nothing new has been installed, no physical damage (dropping, etc). Which leads me to think it's a hardware problem.
What can I do that might help diagnose this better? And if it is hardware, what are my repair options? It was bought in Feb 2020, so it's three years old.
Thanks!!
