There are some reasons for it, I have listed below-
Graphics Card or GPU Issues
Screen Damage
Driver or Software Problems
Loose or Damaged Display Cable
Solutions you can try for this problem-
1. Use on an External Monitor
Connect your laptop to a monitor via HDMI/DisplayPort.
If the external monitor is fine → Likely screen issue.
If the external monitor also shows green lines → Likely GPU or driver issue.
2. Update or Reinstall Graphics Drivers
Go to Device Manager → Display adapters → Update driver.
Alternatively, uninstall the driver and reinstall the latest version from your laptop manufacturer or NVIDIA/AMD/Intel website.
3. Check Display Cable
Disconnect and reconnect the display cable.
Inspect for visible damage.
4. Perform a Hardware Reset
Shut down, remove battery (if removable), hold the power button for 30–60 seconds.
Restart and see if the lines persist.
