Black lines along bottom of screen

[Deshev]

[content removed]

About 2 days ago these black lines appeared on the bottom of my screen. They appear everywhere, even in the bios setup screen. They occasionally will be gone when I open my laptop after it has been closed for a while, but if my laptop falls asleep and wakes back up they reappear. What can I do?

Hello @Deshev 

Sorry to hear that you are having problems ... I would like to help you.

(1) Double check with external monitor connected via vga/hdmi cable. Do you have same error pattern (black lines) on external monitor ?

- Shutdown notebook (No Sleep / No Hibernate)

- Power off external monitor

- Connect vga/hdmi cable

- Power on external monitor

- Power on notebook

(2) Please report your results

So I plugged my laptop into my tv and the black lines were not on the tv. I take this to mean that my display is the issue
