Check What is Causing the Screen Flicker
Step 1 – The easiest way to determine if the flickering is caused by your display drivers is to check is Task Manager flickers along with the rest of the screen. To open Task Manager, press Ctrl + Alt + Delete and then select Task Manager from the menu.
Step 2 – If Task Manager flickers along with the rest of the screen, the problem is probably with your display drivers. If the Task Manager does not flicker with the rest of the screen, the problem is more likely to be caused by an incompatible app.
Step 3 – If you think that it is an app causing the problem, you will need to update or uninstall the app you think is causing the problem. This may be simple to diagnose (if the flicker only occurs when the app is running, for example).
Step 4 – To check for app updates (which might fix the incompatibility), open the Microsoft store app. Click the menu button and select Downloads and Updates. Apply any required app updates listed. If the updates have no effect on the screen flicker, you may need to install the app causing the problem.
Step 5 – To view and uninstall apps, open Settings > Apps and wait for the app list to load. If the flickering has only recently started, use the “Sort by” filter to sort the apps by installation date. Look for the suspect app, select it from the list and click Uninstall.
Fix Your Display Driver
Step 1 – You have two initial options to fix incorrectly working display drivers: update or roll back. If you have recently updated your display driver (or believe an automatic update has occurred), roll back is probably the best option here.
Step 2 – In the search field in your Taskbar, type device manager and then select it from the list of results that appears. Look for Display Adaptors in the list of devices, and click the arrow to expand the entry.
Step 3 – Right-click on the name of your display adaptor and then select Properties (if you are unsure, your display adaptor is the graphics card in your computer, so will have a name like Radeon RX or Gforce GTX, etc.)
Step 4 – Click on the Drivers tab, and then click the Roll Back Driver button and confirm the action. You will then need to restart your computer.
Step 5 – If the roll back does not fix the screen flicker, you can instead try updating the display driver. Follow the steps above to get back to the display adaptor properties. Instead of selecting Roll back in the Drivers tab, click Update.
Step 6 – Follow any instructions on screen to complete the update. Restart your PC and check if the screen flicker has been fixed.
