Connect an HD source (Apple TV, game console, digital TV decoder, Blu-Ray player, notebook, etc.) with HDMI output to a projector or screen via the VGA input. Convert an HDMI signal (720p/1080p) into an analog VGA signal with stereo audio (separately routed). No software installation is required, making it quick and easy to use. Extremely energy-efficient. Powered by the HDMI operating voltage, so no USB power supply is included.
