How to Fix Screen Flickering?

Screen flickering in a laptop or desktop is a visible change in the brightness between cycles displayed on the screen. This constant blinking on the screen may be a real frustrating thing as it destroys the peaceful watching experience.

Fixing screen glitching doesn’t always mean taking the laptop or monitor to the service center, most of the time we can only fix the problem. Let’s see what are the reasons for screen flickering and solutions for the same.

Reasons for Screen Flickering:

In an old PC due to wear and tear as years pass by, and defective old cables due to aging are the main reasons for this problem.

But in new computers screen flickering happens due to many reasons, defective wires may also be one of the reasons. Some of the common reasons for screen blinking are:

• Outdated Display Drivers: Outdated display drivers can cause screen flickering, poor display resolution, and other problems. Your laptop will suffer if the drivers are outdated when the patches, updates, and bug fixes go by sideways.

Here’s how to check for an update and also update if the drivers are outdated.

Go to Settings, in the Windows task button, select the Update & Security tab. Then the laptop will scan automatically for updates and shows the updates if any.

If your laptop doesn’t scan for updates automatically then we can do that by clicking on the Check for Updates tab. If there are updates then proceed to update the drivers by clicking the Install updates icon.

• Installation of Incompatible App: Some time we install applications that are of high specifications and parameters, and the computer may not able to handle them.

In such cases, screen flickering is quite common. To check the app which is incompatible with our PC, we need to go to Task Manager and check if the screen flickers.

If everything flickers except the task manager then there’s an incompatible in the system, if the task manager also flickers long with everything else then this has a separate issue.
