A Simpler Approach

While the ZeeVee offers a more sophisticated solution, with their own UI, Altona is sure to sell a ton of their simple USB to HDMI converter, the HDPix. Priced at $179, the convertor allows you to hook up your computer via USB to any TV (or projector) with HDMI. Its also Mac and PC compatible. On the input side there is both a USB port and a mini jack that you plug into the audio output of your computer. The converter automatically embeds the audio into the HDMI out. I don't see this as a high end solution but it surely is an inexpensive solution for getting your computer output to a TV.
