Constant horizontal line on screen

[Marikey]

My laptop screen has been showing a green (sometimes red, depending on background colour) horizontal line just about the task bar for a few weeks. Some time prior to me noticing the line, the laptop fell onto a carpeted floor from a bed. I did not notice this line immediately post fall.

I've tried a previous fix (opening BIOS, the line is still there) which won't work.

The line is not solid; in some places it is thinner and other places wider. 

Has anyone see this before? 

Thanks, M

Hey there! @Marikey,

As the issue persists on the BIOS page, it certainly sounds like a hardware issue with the PC.

Please contact HP support and get the service options for the laptop.
