This adapter connects to a Mini DisplayPort or Thunderbolt and converts the video signals into HDMI for use on a standard HDTV. When using a Thunderbolt connection, the adapter will also pass audio signals to the HDMI output.
The adapter supports a maximum resolution of 1920x1080p with up to 36-bits total color depth (12-bits per channel). This adapter is unidirectional, so it cannot be used to convert HDMI to a Mini DisplayPort or Thunderbolt output.
This is a cost effective solution for adapting your new Mini-DisplayPort equipped laptop to your current display--HDTV, projecter, etc.--with HDMI input.
Mini DisplayPort to HDMI
Mini-DisplayPort is a miniaturized version of DisplayPort, the newest digital display interface developed by the Video Electronics Standards Association (VESA). Most newer Macbook series laptops come equipped with the Mini DisplayPort interface for external video displays. Check your laptop to make sure it has the Mini DisplayPort connection.
This five-inch adapter is for use with a standard HDMI cable (male to male). Connect the cable to your machine using the adapter, then connect to an external monitor or other display device with HDMI input jacks, and you're all set.
A Note About Audio
This adapter will support audio only if your source device allows audio output through the Mini DisplayPorts interface. If you're not sure, please check with the manufacturer or website, to confirm if your device allows audio out through the Mini-DP interface.
