While Apple brings their latest line of computers to the cutting edge by introducing the Mini-DisplayPort, consumers who want to utilize their Macs with their HDMI equipped HDTV's are forced to use separate audio and video connections.
This adapter connects to a female mini displayport to provide video, a USB output to provide power, and includes a mini toslink to toslink cable to connect from the 3.5mm (1/8 inch) digital audio output of your compatible Mac to the toslink input on the adapter in order to deliver true digital audio and video output to the adapter's female HDMI port. All you need to add is a male to male HDMI cable to connect from the adapter to your television and you're ready to view AND hear movies, games, or anything that's displayed on your Mac.
