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 first ran an HDMI cable from my 32" 720p LCD to the new adapter that I had plugged into the mini displayport and usb port that rests immediately next to it on 13" Macbook Pro. I had to go into System Preferences Display and tell the Mac to clone the displays and then went into System Preferences Sounds and told the Mac to use the USB audio output. The Mac had already chosen the best resolution for my display and I was immediately able to pull up Hulu and watch and listen via my 32" 720p LCD. SUCCESS!
That evening I took the Mac and the adapter to my living room and connected to my 52" 1080p DLP. The Mac remembered the clone displays setting and the usb audio output setting so no configuration would have been necessary this time except that I wanted to bump up the resolution for the 1080p TV. Everything worked perfectly. I streamed a 30 minute sitcom from my file server through my Mac and onto the TV and then pulled up Netflix and watched The Exorcist via their on demand offering.
Not a single glitch. The process worked exactly as I had hoped it would.
If I would change anything - it would be reducing the slack between the mini displayport plug and the usb plug since the plugs on my mac are side by side. And I would also love for the HDMI plug to be male to keep from having to carry two cables around instead of one - but I understand that in reality it is more versatile being made how it is. I would just prefer a cleaner option for my specific needs.
All in all, great purchase.
PROS: Works great with my Macbook Pro (4/2010). Sturdy and easy to install.
Note that the cables have to be connected for the mac to offer the options you need to choose the tv may have to be on too (not sure).
TV: select input HDMI 4 (or whichever HDMI you're plugging into. I used 4.
Computer: After plugging in, simply go to "displays" in System Preferences on the mac and choose to "show displays in the menu bar." Then, from the menu bar at the top of the mac screen, choose to enable "mirroring." Back to System Preferences, choose "sound" and you will see an option to have sound output go through the USB connection. Choose that and you're in business!
When I purchased this adapter the specs page showed support for Dolby Digital and DTS 5.1 audio, I sent 2 emails to firstname.lastname@example.org 1 was answered saying 5.1 support should be automatic, a third email directly to a Tech Support Supervisor asking how to enable 5.1 was not answered but now the spec page no longer indicates 5.1 support. I realize this is a brand-new and EXTREMELY innovative product so 5.1 is probably too much to ask at this price point, but the confusion over the specs, and the poor support loses them points in my rating.
If I had been expecting a 2-channel audio only adapter I would probably give it an 8.
Obviously, I don't want my mac on 24 hrs a days, leeching power. (Actually, the adapter itself also gets pretty warm.) Shutting down and booting up every time you want to watch TV is also a hassle, not something you expect from a home theater system. The only workaround is to reach in the back on the Mini and unplug the USB cable after each use. The system then goes to sleep according to whatever sleep timer setting you chose.
Unable to get any video on my TV. Occasionally, the TV would display a message saying that the signal received was incompatible.
Toggling the overscan setting did not make any difference. Nor selecting any other resolution.
Will test this on another TV one of these days.
