Tech 101: What is an HDMI Port?
High Definition Multimedia Interface (HDMI) provides you with a compact way of transferring high-definition (HD) video and audio from a device to a display. A cable plugs into the HDMI port, found on an HD-capable device such as a game console or an HDTV. A standard HDMI cable can handle 1080i and 720p data, while a high-speed cable works best with 1080p, 4K and 3D data.
