About the video ports on Mac
Your Mac includes one or more video ports, which you can use to connect to a display, TV, or projector.
If your Mac has a USB-C port, you can use USB-C adapter cables to connect your Mac to displays and other devices.
Note: There may be an identifying icon near each video port, depending on your Mac.
Thunderbolt: Connect to a Thunderbolt device, Mini DisplayPort display, or to a DVI, HDMI, or VGA display using an adapter.
Mini DisplayPort: Connect to a Mini DisplayPort using an adapter.
HDMI: Connect to an HDTV with an HDMI port. This port lets you play your computer’s audio as well as its video on an HDTV.
If your display and your Mac have different ports, use an adapter. You can purchase an Apple display adapter from apple.com or an Apple Store.
