As technology advances, the lines between devices continue to blur. One question that has been on the minds of many MacBook users is whether they can use their laptop as an external monitor. In this article, we will delve into the world of display sharing, exploring the possibilities and limitations of using a MacBook as an external monitor.
Understanding the Basics
Before we dive into the details, it’s essential to understand the basics of display sharing. Display sharing, also known as screen sharing or screen mirroring, allows you to share the screen of one device with another. This can be useful for presentations, gaming, or simply extending your desktop.
Types of Display Sharing
There are two primary types of display sharing:
- Screen Mirroring: This method duplicates the screen of one device onto another. Both devices display the same content, and any changes made on one device are reflected on the other.
- Extended Desktop: This method allows you to extend your desktop across multiple devices. Each device displays a separate portion of the desktop, allowing you to work on multiple tasks simultaneously.
Using a MacBook as an External Monitor
Now that we understand the basics of display sharing, let’s explore the possibilities of using a MacBook as an external monitor.

- A Mac with a Mini DisplayPort or Thunderbolt port
- A Mini DisplayPort or Thunderbolt cable
To enable TDM, follow these steps:
- Connect the Mini DisplayPort or Thunderbolt cable to both Macs.
- Restart the MacBook you want to use as an external monitor.
- Immediately hold down the ‘T’ key on the MacBook’s keyboard.
- The MacBook’s screen will go dark, and it will become an external monitor for the other Mac.
Third-Party Software
If you’re looking to use your MacBook as an external monitor for a non-Mac device or a Mac without TDM, you can use third-party software. Some popular options include:
- Duet Display: A popular app that allows you to use your iPad or iPhone as an external monitor for your Mac or PC.
- Spacedesk: A software that allows you to use your Android device as an external monitor for your Windows or Mac computer.
