Mini Displayport 1.1 Male and USB Male Audio to HDMI® Female Converting Adapter
Connect your older Mac® without an HDMI® output to an HDMI display using this Mini DisplayPort and USB Male Audio to HDMI Adapter from Monoprice!
This adapter converts the mini DisplayPort video output to HDMI. Stereo (2-channel) audio is obtained through the USB connection and is mixed with the video to produce a complete HDMI audio/video signal.
Note that this adapter does not support more than 2-channel audio. Additionally, it is unidirectional asnd therefore cannot convert HDMI to mini DisplayPort signals. Finally, on some Macs the video connector blocks the adjacent USB port.

The solution – (Again, for dual monitoring Mac Mini® users only) Use the mini-DVI output for your main display, and the mini display port for the secondary display. That way - disconnecting the second display (mini display port) will not affect the output on the main display (mini-DVI). This will not be an issue if you are using two monitors - and are not disconnecting your mini-DVI adapter.
My Macbook Pro recognized this cable instantly and with a little help from the "knowledge base" tab it was easier to get it working. Now I can watch moves again with my LG 32LH40 tv. Couple this with Kingston 8GB of ram and you have almost an entirely new machine. My last upgrade will be switching to a 120GB ssd hard drive and extend my 3 year old laptop by even a few more years! My only regret with this cable is that if I want to listen to music through the laptop speakers or headphones I have to change it in the system preferences. But the good part is that I don't have to log out to do it, so it is only a minor problem.
PROS: Price is great
Ease of setup
CONS: Switching between audios
I'm very impressed with the picture from my MacBook using this adapter. I've used it with 2 HD LCD TVs - a 1080p 52" and a 1080i 32" - and both worked easily and immediately (I just had to turn on Mirror Display). Desktop displays looked great and even streamed online video content (Hulu, etc.) was surprisingly good (if you've watched streaming content on a Netflix-enabled device, this was very similar). Depending on your screen dimensions, you might need to change the picture zoom on your TV to fit the picture correctly, but that's easy enough.
I've only used the audio through my TV's internal speakers (I haven't tried it with an external receiver/speakers) and it sounded just fine.
I am very happy with the product. It works great.
I would recommend this site for purchasing.
Am sorry the above cable I purchased is not available with microDVI (for all earlier owners of a MacBook Air).
