Before proceeding, let’s look at some of the causes of screen flickering.

There are a few causes of screen flickering on Windows 10. Many computer users (not only Windows 10 users) should understand that screen flickering is either caused by a hardware malfunction or a software blip.
We will not only look at the common causes of screen flickering but how to fix screen flickering in Windows 10 in this guide.
Here are the primary causes
1. Outdated display driver
2. Installing Incompatible apps
3. Check if the monitor’s refresh rate configurations are correct.
4. Screen flickering after installing an update
1. Damaged screen (cracked or broken)
In-Depth Solutions to Try

When Windows 10 display drivers are outdated, the screen will continuously flicker. However, to resolve this issue, you need to follow the below steps.

2. Fixing Incompatible Apps
If you recently installed “graphics-related” apps on your PC, it might begin to behave peculiarly. Also, if you installed other incompatible apps, it could be the cause of screen flickering. So, you should check that all installed apps are compatible with your PC.
Step-by-Step Process for Uninstalling Incompatible Apps

- Click the system settings
- Look for the particular app that you recently installed

3. Adjusting the Monitor’s Refresh Rates
You should note that if you have wrong refresh rate configurations, your Windows 10 PC might flicker.
How to check and adjust the refresh rate configurations
- Go to the start button
- Type Display Settings on the search bar
- Click Display Settings from the list of related results
- Scroll to Advanced Display Settings and click it once
- Click the Display adapter properties for Display 1 on the new window
- A pop-up window should appear with more settings and tabs
- Click the monitor tab and go to monitor settings>screen refresh rate
- Select a refresh rate that matches your PC’s performance and click apply

4. Fixing a Damaged Screen and Replacing Faulty Cables
A damaged screen can also be a cause of screen flickering. This is, however, a hardware issue that should be resolved using an all-inclusive DIY guide or by a professional (if the damage is severe).
Important to Note: First of all, connect the PC to another monitor/display device using a VGA cable or HDMI cable and check how it behaves. If the flickering is still present, you can then physically check the cables.
Step-by-Step Process for Checking and Replacing the Screen
- Physically check the screen to affirm if it is indeed damaged/broken/cracked.
- If the screen is broken, you should carefully remove the LED screen and purchase a similar screen that is compatible with your PC.
- In some cases, the flickering problem might be a result of damaged connector cables. So, you should manually unscrew the PC and check whether the cable connectors from the LED screen to the motherboard are intact.
You can try the following two quick-fix solutions to see if the flickering issue is resolved
- Unplug/remove any external device from the ports
- A simple PC restart can be the solution
If all the above procedures do not resolve the screen flickering, you should perform a complete system restore or a factory reset.
Step-by-Step Process to Restore your PC
- Right-click the start button
- Click “Run” to open a dialogue box
- Type rstrui.exe on the dialogue box and click OK
- A system restore pop up window should appear on your screen
- Follow the instructions to restore the system to a specific restore point
Note that the system restore will not delete system files
A system restore takes your PC back a few days or even months to when it was performing correctly.
Factory resetting your machine should be the last resort if you cannot resolve the flickering issue. However, before factory resetting your PC, you should first and foremost back up all your important files to an external storage drive.
