Connect your display
Connect your display to power, then connect your display to your Mac. Check the ports on your Mac to find out whether you need an adapter. If you're using a USB-C or Thunderbolt adapter to connect your display, the adapter must be compliant with DisplayPort Alt Mode, Thunderbolt 3, or Thunderbolt 4.
If you use an external keyboard and mouse with your Mac notebook, you can close the built-in display after you connect your external display. You might have to press a key or click your mouse to wake the external display. To use your Mac with the display closed, you need to connect your power adapter or connect an external display that also charges your Mac, such as the Apple Studio Display or 23.7-inch LG UltraFine 4K Display.
If your external display doesn't turn on after you connect it to your Mac, connect your display while your Mac is off, then wake or turn on your Mac.
If you have an Apple TV or an AirPlay 2–enabled smart TV, you can use your TV as a separate display for your Mac. Learn how to use AirPlay to mirror or extend your Mac display.
