Flickering Screen Windows 10

 Is Windows 10 or Windows 11 computer screen flashing or flickering? Let's look at the cause of the error and how to fix it.

If your Windows 10 or Windows 11 screen keeps flashing, it could be because of a troublesome app installed or an inappropriate display driver. This problem often occurs when upgrading to Windows 10/11 from an earlier version of the operating system. is, but it can happen at any other time.

There are different ways to fix a Windows 10 or Windows 11 flickering screen.

Let's do the Screen Flickering Test first.

First, you need to find out what could be causing the flashing screen.

For this, open Task Manager by pressing Ctrl + Shift + Esc simultaneously.

Right-click on the taskbar in Windows 10 and select Task Manager

There is no need to use the task manager, just open it.

Now, look at your screen to see if the task manager is flickered.

If it happens with everything else on the screen, the problem may be caused by your hardware or a faulty display driver.

If everything flickers except the Task Manager, the problem may be caused by an app.

Follow the instructions below in order to fix this error.

Check Your Monitor and Cables

Check all the cable connections from the monitor to the computer. Take them out and plug them back in to ensure the cables are secure. If you have an extra monitor cable, plug it in and test it. If you can, try using a different monitor. If this solves the problem, then it's clear that the problem is your monitor.

In this case, contact the manufacturer for assistance or to make a warranty claim.

Set the Correct Refresh Rate

A monitor's refresh rate is the speed at which the screen updates the image per second, measured in hertz (Hz). Basic monitors can usually only handle a 60Hz refresh rate, while more advanced ones can go up to 360Hz It's important that you set a suitable refresh rate for your monitor. Sometimes a monitor manufacturer will support an overclocked refresh rate, but this can cause screen flickering.

To adjust your refresh rate

Press Windows key + I to open Settings.

Click System > Display.

Click Advanced display settings (Windows 10) or Advanced display (Windows 11).

Use the Refresh rate dropdown and incrementally select lower rates until the screen flashing stops. If the flashing continues, revert to your monitor's recommended refresh rate.

Uninstall Problematic Apps

Apps can also cause your Windows 10 PC’s screen to flicker. You need to identify the faulty program first unless you know precisely which app is the problem (in which case, you should uninstall that app using the procedures indicated below).

One way to do this is to find out when your screen started to flicker. If your issue started occurring after you installed a particular program, then that app might be the reason. In this situation, verify if a newer version of the software is accessible by visiting its official website. If there is, install it, and your problem should be resolved.

You should temporarily delete the app from your PC if a newer version is not yet available. Until the app developer resolves the problem, you might need to use a different app.

To begin removing the faulty app, open “Settings” by pressing Windows+i.

Click “Apps” in the Settings window.

Find the affected app by navigating to the right pane and scrolling down. Uninstall the app by clicking it.

To uninstall the app, choose "Uninstall" from the popup. Try restarting your computer to see if the issue has been resolved.

Reseat Your Graphics Card

Even if the issue isn't with your display driver, your graphics card may still be at fault.

Your monitor's display may flicker on and off if your graphics card is not properly installed on your motherboard.

It is simple to determine whether your motherboard has built-in graphics. Remove the monitor cable from your graphics card and plug it into the motherboard's display slot instead. If the flashing stops, you know the graphics card is the problem.

Power off your PC, unplug everything, open the case, and remove your graphics card from the motherboard. Reinstall it carefully, making sure the card properly clips into the motherboard. Do not do this if you find it difficult to work on a computer, as it can make things worse.
