Horizontal lines on the display.

 The images show the display of my laptop on the lock screen and the desktop.

I was told that it could be device driver but it is up to date.

Welcome to the HP support community.

I understand that you are getting horizontal lines on the screen, I am glad to assist you.

If you haven't, Please try an alternate monitor to understand if this is either a hardware or a software failure, 

if the issue does not appear on the alternate monitor, you may need to replace the display assembly on your computer, 

if the issue appears on the alternate monitor/TV as well, re-install the graphics card drivers & update it from the official HP Website: Click here 

If you don’t have an alternate monitor, I recommend checking if the issue appears on the BIOS screen (restart the computer and tap on F10 to access BIOS) 

If the issue does not appear in BIOS, reinstall the graphics card drivers & update BIOS using the above link, 
If it does, you may need to replace the LCD/Repair the computer: 

If the issue occurred after an accident (such as dropping it on the floor, liquid spilled on it, etc.) there could be a hardware failure and in such cases, you may need to get the computer repaired via HP (there could be a charge involved if the PC isn't covered by the accidental damage protection plan) 

Keep me posted.

To thank me for my efforts to help you, please mark my post as an accepted solution so that it benefits several others.

Cheers.
