Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

  • When was the last time it worked without these issues?
  • Have you updated Graphics and Chipset drivers? 
  • Have you checked the display on an external monitor?
  • Could you please share the picture of the display with horizontal lines?

Keep me posted for further assistance.
