If you’ve been using your computer and suddenly you notice there’s an element of the screen flickering, there are solutions to fixing the issue.

In Windows 10, the problem is usually caused by either of these two things:

  • An incompatible app
  • A display driver

In order to know for sure that the screen flickering issue is caused by an app or display driver, you need to check if your Task Manager also flickers.

This will determine whether you need to update the application, or update the display driver altogether.

Here are four tried solutions to fix the screen flickering issue.

How to fix laptop screen flickering

  1. Check Task Manager to fix screen flickering
  2. Update incompatible apps
  3. Update display driver
  4. Disable Windows Desktop Manager

Solution 1: Check Task Manager to fix screen flickering

Do the following:

  • Press CTRL+SHIFT+ESC at the same time to open the Task Manager. You can also right click Start button then select Task Manager. Either of these open it.

If the Task Manager isn’t flickering, then the problem could probably be caused by an app.

On the other hand, if the Task Manager is flickering, a display driver could be the cause.


Solution 2: Update incompatible apps

There are three applications that have been known to cause screen flickering on Windows 10:

  1. Norton AV
  2. iCloud
  3. IDT Audio

Updating the incompatible application (or getting in touch with the manufacturer of the specific app to get an update) usually fixes the problem. If the problem can be isolated on a certain individual app. This, of course, isn’t always the case so we can’t say with certainty whether it’s more of a general problem or just a rogue outdated app misbehaving.

Solution 3: Update display driver

In order to do this, you need to start your computer on Safe Mode, then uninstall your current display adapter, and finally check for driver updates.

How to boot in Safe Mode:

Safe mode starts up your computer with limited files and drivers but Windows will still run. To know whether you’re on Safe mode, you’ll see the words at the corners of your screen.

If the screen flickering issue persists, check whether it occurs while your computer is in Safe mode.

There are two versions:

  • Safe mode
  • Safe mode with Networking

The two are similar, though the latter includes network drivers and other services necessary to access the web and other computers in the same network.

Follow these steps to start your computer in Safe Mode:

  1. Click on Start button
  2. Select Settings – the Settings box will open up
  3. Click Update & Security
  4. Select Recovery from the left pane
  5. Go to Advanced startupadvanced startup windows 10
  6. Click Restart now
  7. Select Troubleshoot from the choose an option screen, then click Advanced options
  8. Go to Startup Settings and click Restart
  9. Once your computer restarts, a list of options will come up.
  10. Choose 4 or F4 to start your computer in Safe Mode

 

enable safe mode PC

A quicker way to get into Safe Mode is to restart your computer then do the following:

  • From the Choose an option screen, select Troubleshoot>Advanced options>Startup Settings>Restart
  • Once your computer restarts, a list of options will come up.
  • Choose 4 or F4 to start your computer in Safe Mode

If the screen flickering problem isn’t there while in Safe mode, then your default settings and basic drivers are not contributing to the issue.

Once you start your computer in safe mode, do the following:

  1. Right click Start
  2. Select Device Manager
  3. Expand Display adapters
  4. Right click the listed adapter
  5. Select Uninstall device
  6. Choose the Delete the driver software for this device box
  7. Select Uninstall
  8. Reboot your computer

 

Once your computer reboots, click Start, choose Settings, then select Update & Security>Windows Update>Check for updates.

If you have many display adapters, you need to disable the added display adapter by doing the following:

  • Right click the added adapter from Device Manager
  • Select Disable
  • Click Yes
  • Turn off your computer
  • Disconnect installation or recovery media (if using it)
  • Turn on your computer

If this doesn’t fix the screen flickering, do the following:

  • Restart in Safe Mode
  • Re-enable the added display adapter
  • Disable the other adapter

Once you’re through and the screen flickering is sorted, exit safe mode so you can get your computer back to normal mode.

How to exit Safe Mode:

  • Right click Start button
  • Select Run
  • Type msconfighow to make emulators run faster on windows pc
  • A pop up will open
  • Go to the Boot tab
  • Deselect or uncheck Safe Boot option box
  • Restart your computer
