The Complexities of Black Horizontal Lines on HP Laptop Screens
Before we get into the solutions, it's important to understand the complexities of this problem. Black horizontal lines on an HP laptop screen can be caused by:

- A faulty graphics card
- A cracked or damaged LCD screen

- Outdated graphics driver

Troubleshooting Black Horizontal Lines on HP Laptop Screens
Once you've determined the cause of the problem, you can start troubleshooting. Here are the steps to fix black horizontal lines on an HP laptop screen:
Check the display cable connections. The first thing you should do is check the connections between the display cable and the motherboard. Make sure the cable is properly plugged in and that there is no visible damage.
- If the cable is loose, plug it in more securely.
- If the cable is damaged, you'll need to replace it.
Update your graphics driver. An outdated or incompatible graphics driver can cause a variety of display problems, including black horizontal lines. To update your graphics driver, go to the website of your laptop manufacturer or the graphics card manufacturer and download the latest driver for your specific model and operating system.
- Once you've downloaded the driver, double-click on the installer file to start the installation process.
- Follow the instructions on the screen to complete the installation.
Adjust your screen resolution. Sometimes, a misconfigured screen resolution can cause display problems. To adjust your screen resolution, right-click on an empty space on your desktop and select Display settings. From there, you can adjust the resolution to a different setting.
- If you're not sure what resolution to use, try setting it to the recommended resolution for your laptop.
- Run a system scan for corrupted files. A corrupted system file can sometimes cause display problems. To run a system scan for corrupted files, open a command prompt window and type the following command:
sfc /scannow
This command will scan your computer for corrupted files and attempt to repair them.
- Reset your laptop to factory settings. If you've tried all of the above solutions and the black horizontal lines are still there, you may need to reset your laptop to factory settings. This will erase all of your personal data, so be sure to back up your files before you do this.
- To reset your laptop to factory settings, go to Settings > System > Recovery and select Reset this PC.
- Follow the instructions on the screen to complete the reset process.
If none of these solutions work, you may need to contact HP customer support or a professional technician for further assistance.
