Hi @SwarajP1,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

Lines appearing on your HP OMEN Laptop - 15 screen can be caused by several issues, such as hardware damage, software glitches, or driver problems. Here are steps to diagnose and resolve the problem.

Test for Hardware or Software Issues

• Restart and Check: Restart your laptop and observe if the lines appear during the HP logo or BIOS screen. If they do, it’s likely a hardware issue.
• External Monitor Test: Connect your laptop to an external monitor using HDMI or DisplayPort.
  • If the lines do not appear on the external monitor, the issue is likely with your laptop's display.
  • If the lines appear on both screens, it may be a GPU or driver problem.

Update Display Drivers

1. Check for Updates:
   • Press Win + X > Device Manager > Expand Display adapters.
   • Right-click your graphics card > Select Update driver > Search automatically for drivers.
2. Use HP Support Assistant:
   • Open HP Support Assistant to check for updates specific to your laptop.

Check Screen Resolution and Refresh Rate

• Right-click on the desktop > Display settings > Advanced display settings.
• Ensure the resolution and refresh rate are set correctly for your laptop (e.g., 1920x1080 @ 144Hz).

Run Diagnostics

• Restart your laptop and press Esc repeatedly, then F2 to enter the HP Hardware Diagnostics.
• Run a Display Test to check for hardware issues.

Inspect for Physical Damage

• Check for any visible damage to the screen or pressure marks.
• Flex or pressure on the lid or hinge can sometimes cause lines. Ensure the laptop is handled gently.

Perform a System Restore

If the lines started appearing after a software update, restore your system to a previous working state:

1. Press Win + S > Search System Restore > Follow the prompts to revert your system.

I hope this helps.

Take care and have a good day.
