What Causes Horizontal Lines on HP Laptop Screens?
Horizontal lines on your laptop screen can stem from different sources. It’s important to first understand what’s causing the issue before jumping into fixes.
1. Physical Damage or Screen Impact
One of the most common reasons for horizontal lines is physical damage to the screen. If your laptop has been dropped, or the screen has suffered any form of impact, it can cause the internal wiring or pixels to malfunction.
If you notice that the lines are only present in certain areas or after a physical impact, the issue could be permanent and might require a screen replacement.
2. Outdated or Corrupted Graphics Drivers
Outdated or faulty graphics drivers can cause display issues like horizontal lines. Windows updates can occasionally conflict with old drivers, especially on systems like Windows 11, causing graphics glitches.
Make sure your drivers are up to date by checking the Device Manager for updates.
3. Loose or Faulty Display Cables
A loose connection between the motherboard and the display panel can cause these lines. Sometimes, simply reseating the cable can resolve the problem.
If you are comfortable with it, you can carefully open up the laptop and inspect the connection. Otherwise, a professional technician can help with this.
4. Software or Operating System Bugs
Operating system bugs are another possible cause. Sometimes, software conflicts or bugs in Windows 10 or 11 can cause display issues.
Try performing a system update or adjusting settings to see if that resolves the issue.
How to Fix Horizontal Line on Laptop Screen HP
If you’re seeing horizontal lines on your HP laptop screen, here’s how you can fix them.
1. Update or Reinstall Graphics Drivers
One of the easiest fixes is to ensure your graphics drivers are up to date.
- Open Device Manager and expand Display Adapters.
- Right-click on your graphics driver and select Update Driver.
- You can also uninstall the driver and let Windows reinstall it after a restart.
Updating your drivers can fix glitches caused by outdated software.
2. Inspect the Display Cable
If you notice lines appear after moving your laptop or the display randomly flickers, the cable may be loose. To fix it:
- Turn off the laptop and carefully open it to check the cable connections.
- If you’re not familiar with the internal components, it’s best to let a professional handle this.
3. Perform a System Update
Sometimes the issue might be a bug within the operating system itself.
- Check for updates under Settings > Update & Security.
- Install any available updates and restart your laptop to see if the issue is resolved.
4. Test with an External Monitor
This test will help you determine whether the problem is with your laptop screen or the graphics card.
- Connect your laptop to an external monitor.
- If the horizontal lines don’t appear on the external monitor, the problem is likely with the laptop’s display, not the GPU.

Is There a Difference Between Fixing Horizontal Lines on Windows 10 and Windows 11?
While both Windows 10 and Windows 11 users experience similar issues with horizontal lines, there are a few differences in how to approach fixes.
1. Graphics Drivers and Compatibility
Windows 11 has a new interface, and it’s still learning how to interact with older hardware. This can cause compatibility issues with certain graphics drivers, leading to glitches like horizontal lines.
Ensure your drivers are compatible with Windows 11, and check for any available updates from the manufacturer.
2. Display Scaling in Windows 11
Windows 11 offers a display scaling feature that can sometimes cause display errors, including horizontal lines.
To check this:
- Right-click on the desktop and select Display Settings.
- Under Scale and Layout, make sure the scaling is set to 100% or your preferred setting.
