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?

Laptop: HP Pavilion Gaming - 17-cd0049ur

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

 

(2Please 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.

Hello @alexanderche 

 

This is screen matrix (technical) error. Live with the error or have the screen replaced.

In your case: Service is required !
- The computer should be disassembled and checked.
[Always recommended] Thermal paste for CPU GPU and bridges should be renewed
