Step-by-Step Fix for Green Lines on Laptop Screen
Step 1: Test with an External Monitor
Begin by connecting your laptop to an external monitor, if one is available. This simple action can clarify whether the issue is confined to the laptop’s display. Ensure that all cables are connected correctly for a reliable test.

Step 3: Update the Graphics Card Driver
If you suspect that the driver is faulty, updating it may resolve the issue. Visit the manufacturer’s website or use dedicated software utilities like Intel Driver & Support Assistant or AMD Adrenalin to obtain the latest version. For a fresh reinstall, consider these steps:
- Download the latest graphics driver from the official support site for your laptop.
- Uninstall the existing driver using Display Driver Uninstaller (DDU).
