The Mini DisplayPort to HDMI Adapter from Gefen allows you to use an HDTV or computer display that features an HDMI interface with a computer that features a Mini DisplayPort or Thunderbolt output. When used with a Thunderbolt port, this adapter doesn't support the data rates and video options of Thunderbolt. An HDMI cable is still required to connect the adapter to the display. This adapter carries a video signal only; it does not support HDMI audio.
Supports digital video resolutions up to 1920 x 1200 @ 60Hz
Compact, lightweight adapter cable fits in any laptop bag
No external power needed
