White appearing on top of the screen when i go full screen

[Zeke05]

I am having a issue with my laptop that the top of the screen goes white before and when i play games the corners of my screen is flickering and now the top of my screen where the white pixels appearing turns to black line now. I am wondering if it is a LCD issue or video graphics?

Hi @Zeke05,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your laptop!

We're thrilled to have the opportunity to assist you and provide a solution.

Try these steps:

LCD Screen Issues:

• Cracked or Damaged Screen: Broken or damaged screens can cause lines, patterns, or unusual colors. Over time, these can evolve into darker spots or lines.
• Screen Defects: Liquid spillage or impacts can damage the internal screen components, causing discoloration or lines.

Video Graphics Issues:

• Outdated Drivers: Graphic issues can arise from outdated or corrupted drivers.
• Incorrect Display Settings: Misconfigurations in display settings might also cause flickering or line issues.

Troubleshooting Steps:

Visual Inspection:

• Check for any visible damage, such as cracks or spots on the screen.
• Ensure no liquid has come into contact with the screen recently.

Update Graphics Driver:

• Ensure your graphics driver is up to date. You can use HP PCs - Updating drivers and software with Windows Update for guidance.

External Display Test:

• Connect your laptop to an external monitor. If the issue persists on the external monitor, it's likely a graphics card issue rather than the LCD.

Safe Mode Boot:

• Boot your laptop in Safe Mode to check if the issue resolves itself in a minimal driver environment.

HP Hardware Diagnostics:

• Use the HP PC Hardware Diagnostics (UEFI) tool to test for any hardware-related issues. You can initiate this tool by pressing the F2 key during boot, selecting Component Tests, and then selecting Video.

I hope this helps.
