Apple's own Mini DisplayPort to Dual-Link DVI Adapter—the one you use to connect a Mini DisplayPort to a 30-inch display—has problems. These problems were never fixed with a software update, unfortunately. But Kanex thinks they can do better.

Got a new Mac and finding yourself struggling to find a Mini DisplayPort to HDMI adapter that supports video and audio output? No worries. The Kanex iAdapt should have you covered.

The dream of putting HDMI content (Blu-ray player, Xbox 360, PS3 or even another computer) into a 27-inch iMac has FINALLY come true. Kanex, who have done MDP to HDMI adapters, now goes the other way with the upcoming accessory.

It's the digital audio version of the Kanex Mini DisplayPort Adapter we reviewed before, which takes your digital audio and Mini DisplayPort video and mixes it into one HDMI signal for your TV.

Frustratingly, Mini DisplayPort doesn't include audio, so to get sound when outputting to an HDTV using HDMI, you'd need to use yet another cable. This adapter uses USB for audio, so you get the full A/V with just one cable.
