Hi,

You need to identify first if it's happening as well in BIOS because if it does it's could be safe to say that your display is faulty. But here's some steps you might want to try as well.

1. Installing the latest graphics card driver.
- Uninstall the old driver of your graphics card in Programs and Feature and in Device Manager
- Download and install the latest driver that can be found from NVIDIA or AMD depending on what you have in your laptop. Links are listed below for both manufacturer.

- Be sure reboot the PC for all the changes to take effect.

2. Using an external monitor.
- If you have an available external monitor hook it in the laptop and observe if you'll experience the same problem with it.
- Doing this step would isolate if there's other problem in the laptop. (Graphics Card)
