Are you looking to turn off your Mac screen while mirroring? Fortunately, it’s possible to mirror your Mac screen without having the display on. This is great if you want to save power, or if you just want the convenience of not having to worry about setting up a second monitor. Here’s how to turn off your Mac screen while mirroring:

First, make sure that Screen Sharing is turned off. To do this, go to System Preferences > Sharing and uncheck the box next to Screen Sharing.

Next, connect your external monitor to your Mac using an HDMI cable. Once connected, press brightness down repeatedly until your Mac’s display dims all the way down.

Finally, right-click on the Windows desktop and select Display Settings from the drop-down list. Select Show only on 2 from the drop-down list and then click Apply. Your external monitor should now be displaying whatever is being mirrored from your Mac, but your Mac’s display will remain dark.

If you ever want to re-enable your Mac’s display again, simply repeat these steps but select Show only on 1 in step three instead of Show only on 2.

Turning Off Mac Screen When Using External Monitor

The simplest way to turn off your Mac screen when using an external monitor is to dim the Mac screen all the way down. To do this, just press the brightness down button repeatedly until the screen is completely dimmed. Once your Mac’s screen is off, you can then connect your Macbook to your external monitor using an HDMI cable. Your external monitor will then be active and functioning as your primary display, while your MacBook’s built-in keyboard and trackpad are still available for use.

Making a Laptop Screen Black When Connected to a Monitor

To make your laptop’s screen black when connected to a monitor, first, plug the monitor’s power cord into an outlet and then plug the video cable into the video output port on the PC and the video input port on the monitor. Turn on the monitor. Right-click on your Windows desktop and select Display Settings from the drop-down list. Select Multiple Displays from the left menu, then select Extend these displays from the Multiple Displays sections. Now all you need to do is select Show only on 2 from the drop-down list for your laptop’s display. This will make your laptop screen go black but will still allow you to view your content on the external monitor.

Displaying on an External Monitor on a Mac

To display only on an external monitor, you’ll need to first connect the monitor to your Mac. Once connected, open the System Preferences, then click on Displays. From here, you can select the Display option for your external monitor. On the right side of the window, select the Arrangement tab and uncheck the box next to Mirror Displays. Finally, click on the Display tab and change the Resolution setting to match that of your external monitor. That’s it! Your Mac should now be displayed only on your external monitor.

Closing Mac and Using External Monitor

Yes, you can close your Mac and use an external monitor! To do so, first, you need to connect an external mouse and monitor to your Mac. If you’re using a Bluetooth mouse and keyboard, make sure that Bluetooth is on and that the peripherals are paired with the Mac. Once everything is connected, your Mac notebook’s Desktop should appear on the external display. Finally, you can close the lid of your Mac and continue to use the mouse and keyboard with the external monitor.

Closing a Mac Without Turning Off an External Monitor

To close your Mac without turning off an external monitor, you need to enable Clamshell mode. To do this, click the Apple menu and select “System Preferences,” then choose “Energy Saver.” Set the Computer Sleep and Display Sleep sliders to “Never” to prevent your computer from sleeping when the lid is closed. Once this is done, you should be able to close the lid on your Mac while it remains connected to an external display.

Troubleshooting Mac Screen Not Turning Off

It’s possible that your Mac may not be automatically turning off its display due to the Energy Saver settings. To check this, open System Preferences and navigate to the Energy Saver settings. Look for the setting “Turn display off after” and make sure it is set to a time other than Never. If it is set to Never, change the setting to a time such as 10 minutes and save your changes. That should enable your Mac to turn off its display after the specified amount of time has elapsed.


The Mac Screen is a handy tool that can be used to display information from your Mac onto an external monitor. It is easy to set up and use, allowing you to view larger versions of documents, images, and videos without having to strain your eyes. Additionally, it is possible to turn the screen off completely and still use the built-in keyboard and trackpad. With the ability to dim the screen all the way down, it is a great tool for conserving energy as well. All in all, the Mac Screen is a great addition to any Mac setup.
