Lower half of screen has pink lines

[Carl_Hart_2]

 

My screen has had pink lines on the lower half for about a week now. It started randomly one day when I turned my computer on and I didn't really know what caused it since it shouldn't be damaged. And now I'm getting worried because it feels like it's slowly spreading to cover the entire screen. I don't know what to do, so if someone could offer some help, I would very much appreciate it.

Hi @Carl_Hart_2,

Welcome to HP Support Community.

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

I can understand how concerning it must be to see pink lines spreading across your screen, especially when you’re unsure of the cause. Let’s go step by step to diagnose the issue and find a solution.

A Few Quick Questions to Understand the Issue Better:

Do the pink lines appear in the BIOS or during startup (before Windows loads)?

• Restart your laptop and press Esc + F10 or F2 to enter the BIOS.
• If the lines appear in the BIOS, it could be a hardware issue (screen, cable, or GPU).
• If they don’t appear, it’s likely a software or driver issue.

Do the lines change when you adjust the screen angle?

• If they flicker or disappear when moving the lid, it could be a loose display cable or hardware fault.

Have you connected the laptop to an external monitor?

• If an external display doesn’t show the pink lines, the issue is likely with your laptop’s screen.
• If the external display does show the lines, the issue might be with the graphics card or driver.

Troubleshooting Steps:

1. Update Display Drivers

• Right-click the Start button → Device Manager → Expand Display Adapters.
• Right-click your graphics card (Intel/AMD/NVIDIA) → Update Driver → Search automatically for drivers.
• If the issue persists, try rolling back the driver: Right-click the graphics card → Properties → Driver tab → Roll Back Driver (if available).

2. Check for Windows & Firmware Updates

• Go to Settings → Windows Update and check for updates.
• Visit HP Support to check for BIOS and firmware updates for your model.

3. Run HP Hardware Diagnostics

• Turn off your laptop.
• Press Esc repeatedly, then press F2 to open HP PC Hardware Diagnostics.
• Run the Display Test to check for hardware issues.

4. Check for Overheating or Pressure on the Screen

• Overheating can sometimes cause screen artifacts. Make sure your laptop is well-ventilated.
• If something has pressed against the screen (e.g., heavy objects in a backpack), it might have caused damage.

5. Try a Hard Reset

• Turn off the laptop, unplug the charger, and remove the battery (if removable).
• Hold the power button for 30 seconds, then reconnect everything and power it back on.

6. If It’s a Hardware Issue

• If the pink lines appear in the BIOS and on an external monitor, the issue may be with the graphics card.
• If they only appear on your laptop screen, it could be a faulty LCD panel or a loose display cable.

Let me know what you observe at each step, and we’ll figure out the best solution together!

I hope this helps.

Take care and have a good day.
