[Kevinski66]

Hi, i have a HP Pavillion 15 which 2 days ago acquired a thin horizontal line a third of the way up the screen, i have tried restarting, battery out etc etc but its still there, just wondering if its a hardware issue or a windows issue???

Hello @Kevinski66 

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

Hi, thank you for your help, i have done what you said and there is no line on the external monitor so i presume its an issue with my laptop screen ?

Thanks

Kevin
