HDMI (High-Definition Multimedia Interface) is a compact audio/video interface for transferring uncompressed video data and compressed/uncompressed digital audio data from a HDMI-compliant device ("the source device") to a compatible computer monitor, video projector, digital television, or digital audio device.[1] HDMI is a digital replacement for existing analog video standards.
An HDMI cable looks like a cell phone USB charging plug but much larger. This connection is used widely for all kinds of modern media. I have HDMI connecting my home theater system.
