Hi guys,
I have another problematic laptop here, a Dell Latitude 7420 2-in-1 with touch display.
Motherboard is Compal LA-K371P Rev.3.0.
The laptop has a strange display problem, see attachment for more details. This problem is not windows related, as soon as you start the display has those lines even in the Bios. If i attach an external monitor, the lines do not appear there.
I was able to get my hands on a second display, but the problem persists, so it seems to be something different.
any ideas?
