Update your graphics card drivers
If the cables are not the problem, the problem may be with your graphics card drivers . Drivers are software that allows your PC to communicate with external devices, such as the display. If the drivers are outdated or incompatible, they may cause malfunctions.

- Click Update & Security.
- Click Windows Update. You'll see it in the navigation menu on the left side of the window.
- Click Check for updates. It's at the top of the page.
- If driver updates are available, click Install Now to download and install them.
To update your graphics card drivers , you can follow these steps:
- Download the Intel® Driver and Support Assistant to your computer.

You can also use software like Malwarebytes or AdwCleaner to remove any adware or spyware that may be slowing down your PC.
Clean your PC and check its temperature
Finally, the problem may be linked to overheating of your PC or your screen. If your PC or display gets too hot, it may turn itself off and on to prevent irreversible damage . To avoid this, you must regularly clean your PC and your screen with a soft cloth and a suitable product.
