Here’s an impressive little USB to HDMI dongle. As you may have figured out, the Grand Cinema HD dongle allows you to transform any (or almost) PC into a home cinema. 
Just plug it into your PC via USB and connect it to your TV via HDMI. If this solution only supports 1280×720 or 720p in output via HDMI, you can connect many of these babies to as many TVs as you want… Below you’ll find a graph for a better understanding of what it’s all about, but you can get the ultimate desktop setting with seven TVs giving you an impressive 9960×720 resolution.

Not only will this setting allow you to transfer video, but it will also take care of your audio feed via the HDMI.
