What is an HDMI socket on a TV?

HDMI (High Definition Multimedia Interface) is an industry-standard audio/video interface that transmits compressed and uncompressed video data and digital audio data from an HDMI-compliant device ("the source device") to a compatible computing device, or display device, such as a television, projector, or computer monitor ("the sink").

HDMI sockets can transmit multiple uncompressed digital audio and video signals simultaneously. HDMI sockets support all currently standardized resolutions as well as all digital audio formats commonly used by DVD players, Blu-ray Disc players, and other consumer electronic devices.

On a TV, an HDMI socket is a port that allows you to connect devices that have an HDMI output, such as Blu-ray players, DVD players, game consoles, and computers. The HDMI socket on a TV is usually located on the back or side of the TV.
