How to fix screen flickering in Windows 11

If you’re experiencing a flickering or glitching screen on your Windows 11 device, it can be quite frustrating. However, with some troubleshooting steps, you can often resolve the issue yourself. Here’s a comprehensive guide on how to fix screen flickering in Windows 11.

This issue can stem from various sources, including hardware problems, driver conflicts, or refresh rate settings. Thankfully, with a systematic approach to troubleshooting, you can often fix the issue on your own without needing professional assistance.

Check hardware connections

First, ensure that all hardware connections are secure. Cabling is always the first thing to check, as it is the most prone to becoming loose or damaged. If you’re using an external monitor, check the following:

1. Cable connection: Ensure that the connection between your monitor and your computer is secure. Whether you're using HDMI, DisplayPort, DVI, or VGA, make sure the cable is firmly plugged in at both ends.
2. Use a different cable: If the cable appears worn or frayed, try a different one to see if the issue is resolved.
3. Test with another monitor: If possible, connect your computer to a different monitor. This will help ascertain whether the problem lies with the monitor or the computer.

Update graphics drivers

Outdated or corrupted graphics drivers are a common cause of screen flickering. There are two (2) ways of updating your graphics drivers: Download from the manufacturer's website or use Device Manager. To obtain the latest drivers, refer to the manufacturer's website first, and then use Device Manager as a secondary source.

Via the manufacturer’s website

You can download the latest drivers directly from the manufacturer’s website for more control over installation options. Keep in mind that manufacturers may release updated drivers after Microsoft releases its monthly updates.

Via Device Manager

3. Change refresh rate: Scroll down to Advanced display settings and check the refresh rate. Make sure it's set to the optimal value recommended for your monitor. Typical refresh rates include 60Hz, 120Hz, or 144Hz, depending on your monitor specifications.
