HDMI2VGAA connects your HDMI equipped computer to your VGA monitor or projector, allowing resolutions up to 1920x1200. Additionally, while converting the video signal from digital to analog, it also passes through the audio signal, which can be outputted through the included 3.5mm audio plug. Also included is a micro-USB to USB plug that allows the converter to be used without the need for a separate power source, maybe this a complete, but simple solution.
