How to fix Windows 7 screen flickering
Flicker can be a problem on CRT monitors. LCD monitors (also called flat-panel displays) don’t create flickers. 9jahowto creates an excellent solution on how to correct monitor flicker on Window 7.
A flickering CRT monitor can contribute to eyestrain and headaches. 9jahowto creates a fantastic solution on how to correct monitor flicker on Windows 7, and you can reduce or eliminate traces by increasing the screen refresh rate. A refresh rate of at least 75 hertz generally produces less flicker. (Because LCD monitors don’t create flicker, they don’t need to be set at high refresh rates.) For more information about choosing the best refresh rate for your monitor.
To correct flicker:
- Go to settings
- Open screen Resolution
- Click Advanced settings.
- Click the Monitor tab, and then, under Screen refresh rate, click the screen refresh rate you want. The monitor will take a moment to adjust. If you’re going to keep the changes, click Apply. If you don’t apply the changes within 15 seconds, the refresh rate will revert to your original setting.
If you notice a flicker on a CRT monitor, you might need to change your screen resolution before changing the refresh rate. The higher the resolution, the higher your refresh rate should be—but not every screen resolution is compatible with every refresh rate. For more information, see Change screen resolution.
