Hi @Veerla 

Welcome to HP Community!

I understand that you are getting Horizontal line on your PC display, I am glad to assist you

Here's what you need to do, to identify the issue and resolve it accordingly:

• If not done already, check if it works fine on the BIOS screen to identify if it's either a hardware or a software issue:
  • If it works fine on the BIOS (Accessed while tapping F10 during a restart) it's a software issue & I suggest creating a new user account to check if that works better, for starters)
  • However, if it doesn't work within the BIOS either, I'm afraid it's a hardware malfunction.

In many cases, the display connector behind the internal notebook screen no longer sits 100% and leads to such errors.

Please check if you have same error on external monitor.

If the picture on external monitor is OK, it is most likely due to internal display cable or the screen is defective.

While you respond to that, I have a few more steps that should help: 

Attempt to run a test from the HP hardware diagnostic tool, using this link: Click here for details.

If the issue appears on the diagnostics, it could again, determine a hardware failure,

If they don't appear on bios & the hardware tests passed: please update the BIOS & Chip-set drivers from the HP website using this link: Click here

Please perform these steps and Feel free to reply to your public post for any further assistance.
