OS X Connect a display
You can easily view your Mac desktop on a display, such as an Apple Thunderbolt Display, or on your TV.
Connect an Apple Thunderbolt Display: Plug the display’s cable directly into the Thunderbolt port 
on your Mac.
Connect an Apple LED Cinema Display: Plug the display’s cable directly into the Thunderbolt port on your Mac.
Connect a TV or display with an HDMI connector: Plug the cable directly into the HDMI port on your Mac. For more information about using a TV, see Use your TV as a display.
Connect a display with a VGA connector: Use a Mini DisplayPort to VGA Adapter to connect the display to the Thunderbolt port on your Mac.
Connect a display with a Mini DisplayPort: Plug the display’s cable directly into the Mini Display port 
on your Mac.
If your display uses a video port that’s not available on your Mac, you may be able to use an adapter to connect your display. For example, if your Mac doesn’t have an HDMI port, you can use a Mini DisplayPort to HDMI video adapter with the Thunderbolt port on your Mac. If you’re using a MacBook with a USB-C port, use a USB-C Digital AV Multiport Adapter or a USB-C VGA Multiport Adapter.
