Screen flickering in Windows is most commonly caused by problems with your display drivers. Here's a breakdown of the issue and how to troubleshoot it:
Understanding the Problem:
A flickering screen can be distracting and frustrating. It often manifests as a rapid flashing or blinking of the display, sometimes accompanied by distortions or changes in brightness. While display drivers are a frequent culprit, other factors can also contribute.
Troubleshooting Steps:
-
Check Cables and Connections:
- Ensure the monitor cable (HDMI, DisplayPort, VGA, DVI) is securely connected to both your computer and monitor.
- Try a different cable to rule out a faulty connection.
- If using an external monitor, try a different port on your computer.
-
Update or Roll Back Display Drivers:
-
Safe Mode: Start your computer in Safe Mode. This loads Windows with a minimal set of drivers and services, helping to isolate driver-related issues. To enter Safe Mode:
- Press the Windows key + I to open Settings.
- Go to Update & Security > Recovery.
- Under Advanced startup, click Restart now.
- After your PC restarts to the Choose an option screen, select Troubleshoot > Advanced options > Startup Settings > Restart.
- Press 4 or F4 to start your PC in Safe Mode.
-
Device Manager: Once in Safe Mode:
- Right-click the Start button and select Device Manager.
- Expand "Display adapters."
- Right-click your graphics card (e.g., NVIDIA GeForce, AMD Radeon, Intel UHD Graphics).
- Select "Update driver" and choose "Search automatically for drivers."
-
Roll Back Drivers: If the problem started after a recent driver update, roll back to the previous version:
- In Device Manager, right-click your graphics card.
- Select "Properties."
- Go to the "Driver" tab.
- If the "Roll Back Driver" button is available, click it and follow the instructions. If the option is greyed out, it means there is no previous driver to roll back to.

-
Hardware Acceleration:
- In some cases, disabling hardware acceleration within specific applications may resolve the issue. This setting is not present on Windows 10 and newer.
- The method of disabling this depends on the application
-
Monitor Refresh Rate:
- Ensure your monitor refresh rate is set correctly.
- Right-click on the desktop and select "Display settings."
- Click "Advanced display settings."
- Select your monitor (if you have multiple).
- Choose "Display adapter properties for Display [Number]".
- Go to the "Monitor" tab.
- Select the appropriate refresh rate (usually 60Hz or higher).
-
Hardware Issues:
- In rare cases, screen flickering can be a sign of a failing graphics card or a problem with the monitor itself.
- Try using a different monitor to see if the issue persists.
- If you suspect a hardware problem, consider contacting a professional technician or the manufacturer for assistance.
-
Software Conflicts:
- Certain programs might be interfering with your display settings. Check for any recently installed software that might be related to graphics or display settings. Uninstall any such programs to see if the problem goes away.
Summary:
Most screen flickering issues are related to display drivers. Updating, reinstalling, or rolling back your drivers are usually the first steps to take. If that doesn't resolve the problem, investigate other potential causes, such as cable issues, refresh rate settings, hardware problems, or software conflicts.
