What to Know

  • Plug an HDMI cable into your Mac and the projector. (You might need an adapter). Turn on the projector and open the lens.

This article outlines how to connect a projector to your Mac and figure out which ports you have and any adapters you need.

Identify the Ports on Your Mac

The key to connecting your Mac to a projector is understanding the ports on your computer. Many MacBooks do not have a built-in HDMI port, but you can still connect with HDMI using a port adapter.

Apple publishes user guides for its products so you can see which ports and adapters you'll need. You can also look at the Apple port shapes and symbols guide or enter your Mac's serial number on the Apple Tech Specs page to guide you. Here's an overview of the types of ports found on MacBooks.

  • HDMI Port: If you do have an HDMI port on your MacBook, you can connect directly to a projector with the projector's HDMI cord without using an adapter. The HDMI cable is likely included with your projector.

  • USB-C or Thunderbolt Port: You will need to purchase the Apple USB-C Digital AV Multiport Adapter.
  • Mini Display Port: This port looks similar to the thunderbolt port but has a monitor icon rather than the thunderbolt icon. Check the Apple port guide to be sure about your specific ports.

Connect Your Mac to a Projector

  1. Turn on your MacBook.

  2. Plug your HDMI cable, or your adapter into your MacBook port, and connect the HDMI cable.

  3. Turn on your projector. Plug the other end of the HDMI cable into your projector.

    Your projector and MacBook must be powered on when you connect them with the HDMI cable. Otherwise, your MacBook will be unable to find the projector so that you can adjust the settings. You must also slide or open the projector view window.

Customize Your Display From Your MacBook

Synchronize Your MacBook for Display. Click on the Apple logo > System Preferences > Displays > Detect Displays. From here, select your projector from the drop-down list if it is not already selected.

Click Arrangement and check the Mirror Displays box to mirror your screen to the projector so that your monitor is the same as the projector screen.

Benefits of Connecting to a Projector

Connecting your Mac to a projector allows you to extend your monitor to a screen as your primary display or mirror what is happening on your screen to an audience. You'll need a high-definition multimedia interface (HDMI) cable to connect your MacBook to the projector. HDMI is the most common interface standard used to transmit video digitally through an HDMI cable and is compatible with HD content, including Blu-ray.
