Question 1: How do I connect the adapter from my computer to my TV or monitor?

[ Edited ]

Note: You do not need this cable if you have a Thunderbolt display. Instead, use the Thunderbolt cable that is integrated on the back of the Thunderbolt display.

 

  1. Connect the adapter’s mini display port connector to your computer’s display port or Thunderbolt port, then connect the adapter’s HDMI jack to an HDMI cable (not included).
  2. Connect the HDMI cable to your monitor’s HDMI connector.
  3. Connect your TV or monitor to a power outlet.
  4. Turn on your computer and TV or monitor.
  5. Switch your TV or monitor to the HDMI input/source that matches the input jack your computer is connected to. Your computer desktop content is displayed on the TV or monitor.
  6. For information on configuring your screens, see Question 4, Question 5, and Question 6.
