What can I do to eliminate the green lines on my Windows 10 laptop?

1. Install the latest graphics card driver

Display-related issues, such as green lines on the top or bottom of the laptop screen, might be caused by outdated or faulty graphics card drivers. Update your display drivers to the most recent version available to resolve the problem.

While you may manually update graphics card drivers from the device manager, graphics driver updater software such as DriverFix can make the process safer and more convenient.

2. Upgrade your BIOS

  1. Type cmd while holding down the Windows key.
  2. Choose Run as Administrator from the context menu when you right-click on Command Prompt.
  3. Type the following command in the Command Prompt window and press Enter:

  8. Extract the Zip file containing the BIOS and file.
  9. To upgrade the BIOS, open the readme.txt file and follow the instructions.

3. Look for problems with the hardware

  1. By booting into your BIOS, you can see if the horizontal green line on your laptop screen is caused by hardware issues with your display or a software glitch.
  2. Shut down your computer to accomplish this.
  3. To enter BIOS in Windows 10, hit the F2/Del/F10/F12 key, depending on your laptop manufacturer. Then, to turn it on, push the power button. For further information on accessing BIOS, consult your laptop’s user manual.
  4. Check to see if the horizontal green line is visible in the BIOS. If it isn’t visible, quit BIOS, restart your computer normally, and then follow the rest of the instructions below.

A visible green horizontal line indicates a possible display hardware failure in the BIOS. Contact your laptop manufacturer about replacing your LCD.

Alternatively, connect your laptop to a second display monitor. Check to see if the green horizontal line is also visible on your secondary display. If not, you may need to get your laptop display replaced to resolve the issue.
