1.Monitor cables can be loose if they weren’t inserted properly the first time. These loose cables can cause your screen to flicker. They may even loosen over time if they weren’t plugged in securely enough.

To check for this problem, unplug your monitor’s cable and plug it back in securely—from both the back of the monitor and on the PC. Make sure that the cable is fully tightened and that it doesn’t look or feel loose.

2. Apps can also cause your Windows 10 PC’s screen to flicker. For instance, in the past, some Norton products caused screen flickering issues on Windows 10 PCs.

Unless you know exactly which app is causing the issue (in which case, you should uninstall that app using the steps listed below), you need to identify the problematic app first. One way to do this is to find out when your screen started to flicker. If your issue started occurring after you installed a particular app, then that app might be the culprit. In this case, check the app’s official site and see whether a newer version is available. If there is, install that version, and your issue will likely be fixed.

• To begin removing the faulty app, open “Settings” by pressing Windows+i.
• Click “Apps” in the Settings window.
• Here, scroll down the right pane and find the problematic app. Click the app and select “Uninstall.”

3.Microsoft says that screen flickering is often caused by display drivers. An easy way to fix this is to reinstall your display drivers.

On the Device Manager window, click the arrow next to “Display adapters.” Right-click the adapter that shows up in this expanded menu, then select “Uninstall device.” In the Uninstall Device window, enable the “Delete the driver software for this device” option. Next, click “Uninstall.”

Restart your PC.
