HP Laptop: thin black line on my screen

[alexanderche]

On my screen appeared a thin black horizontal line (near the top of laptop screen). As I can see, it's not even one pixel wide and not noticeable at some angles. It's not software problem because I see it in both windows and linux as well as boot manager. What can it be, and can it be fixed?

Hello @alexanderche 

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 the same error pattern on external monitor ?

- Power off external monitor

- Connect vga/hdmi cable

- Power on external monitor

- Power on notebook

(2) Please report your results

Well, I can't really test this cause I don't have any external monitor, but I'm quite sure that this is the laptop's monitor problem cause it is reproduced in windows/linux/bios/boot manager. I'll try to find a monitor to test and give further info later.

For now, I added a video. Hope this will be helpful.
