Hi @Ishaan101010101,

Welcome to the HP Support Community.
 

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

I understand you're experiencing horizontal flickering lines on the bottom half of your laptop screen during or after gaming. I also understand that the screen still functions, but the flickering is intermittent and sometimes corrects itself briefly.

We’re here to help you identify the cause and resolve the issue

Step 1: Run HP UEFI Display Diagnostics (Built-in Tool)

Please perform a pre-boot display test using HP PC Hardware Diagnostics.

How to run the test:

1. Power off the computer.
2. Press the power button, and immediately press the Esc key repeatedly (once every second) until the Startup Menu appears.
3. Press F2 to enter HP PC Hardware Diagnostics.
4. Use the arrow keys to select:
   • Component Tests > Display > Display Test
5. Follow the on-screen instructions.

If flickering or lines appear during this test, it confirms a hardware issue.

Step 2: Update Your HP Drivers and BIOS

The issue may be related to outdated graphics drivers or BIOS firmware. Please install the latest official drivers from the HP support website.

🔗 Official HP® Support

1. Enter your exact product number or serial number
2. Download and install:
   • Graphics Driver
   • BIOS Update
   • HP System Event Utility
   • HP UEFI Diagnostics (if not already installed)

I hope this helps.

Take care, and have an amazing day!
