How to turn off laptop display when using external monitors

Last Updated: Jan 29, 2024 by

If you use your laptop with an external monitor, you may have noticed that your laptop display stays on even when you close the lid or connect to an external display. This can be frustrating, especially if you want to save battery or reduce distractions. In this article, we will discuss how to turn off your laptop display when using external monitors.

Brightness Control

The first step to turning off your laptop display is to adjust the brightness settings. Most laptops have a function key that allows you to adjust the brightness of your display. Look for a key with a sun icon or the letters “Fn” on your keyboard. Press and hold the “Fn” key and then press the key with the sun icon to decrease the brightness. Keep pressing until the display turns off completely. This method may vary depending on your laptop model, so refer to your user manual for specific instructions.

Power Settings

Another way to turn off your laptop display is through your power settings. On a Windows laptop, go to the Control Panel and click on “Power Options.” From there, click on “Choose what closing the lid does” on the left-hand side. Under “When I close the lid,” select “Do nothing” for both “On battery” and “Plugged in.” This will allow you to close the lid without the laptop going into sleep mode and the display will turn off. On a Mac, go to System Preferences and click on “Energy Saver.” Under “Battery” and “Power Adapter,” select “Turn display off after” and adjust the slider to your desired time.

Display Settings

If you are using an external monitor, you can also turn off your laptop display through your display settings. On a Windows laptop, right-click on your desktop and select “Display settings.” Under “Multiple displays,” select “Show only on 2” (or whichever number corresponds to your external monitor). This will turn off your laptop display and only show the display on your external monitor. On a Mac, go to System Preferences and click on “Displays.” Under the “Arrangement” tab, uncheck the box next to “Mirror Displays.” This will turn off your laptop display and only show the display on your external monitor.

Third-Party Software

There are also third-party software options that can help you turn off your laptop display when using external monitors. These programs allow you to customize your display settings and easily switch between using your laptop display and external monitor. Some popular options include DisplayFusion, Dual Monitor Tools, and Actual Multiple Monitors.

Conclusion

By using these methods, you can easily turn off your laptop display when using external monitors. This can help save battery life, reduce distractions, and improve your overall productivity. Experiment with different methods to find the one that works best for you. Have any other tips for controlling your laptop display? Let us know in the comments.
