HDMI simply means High Definition Multimedia Interface. It is the most commonly used HD signal for transferring high-definition audio and video from a source, such as a computer or TV cable box, to a computer monitor, projector, or TV.
About 20 years ago, the goal of the HDMI initiative was to improve an existing connection. This was achieved by creating a more minor connection to enable embedded audio support and deliver higher resolution video signals. Today, HDMI is widely accepted, with the average computer monitor and TV supporting this interface.
In less than a decade, the success of HDMI was huge, and the shipment exceeded those of DVI. Today, all HDTVs have at least one HDMI port.
