@Dan, so i just using a Thunderbolt and no internal display , that will be ok ?


Yes, you will be using the external HDMI display (not your broken internal)


Also did you check to see if the display is covered under warranty? Visit an Apple Store or authorized support center. As long as you haven't physically damaged your system they should fix it for free.

I would leave things alone here on your laptop system and just get a Thunderbolt to HDMI adapter cable.

The internal display connection is not HDMI it's LDVS and not designed to be connected at the distance you would want to hook up an external monitor (<4").


Here's the adapter you will need: Mini Display Port (aka Thunderbolt) to HDMI adapter

Here's the direct info on video output from Apples site:

  • Thunderbolt digital video output
  • Native Mini DisplayPort output
  • DVI output using Mini DisplayPort to DVI Adapter (sold separately)
  • VGA output using Mini DisplayPort to VGA Adapter (sold separately)
  • Dual-link DVI output using Mini DisplayPort to Dual-Link DVI Adapter (sold separately)
  • HDMI audio and video output using third-party Mini DisplayPort to HDMI Adapter (sold separately)

FWIW, I have a Thunderbolt Unibody MBP with a non-functional display. I've found that it's easier to use with an external display if you disconnect the cable to the external display (all the steps in the linked guide, up through Step 11) - if the computer can still see the built-in display, it defaults to that display as the primary. Disabling the dead display forces the video to the external monitor, and saves you some frustration.
