What is an HDMI Port?
HDMI, or High-Definition Multimedia Interface, is a standard for transmitting high-definition audio and video signals over a single cable. Since its introduction in 2003, it has become a prevalent choice for connecting devices such as televisions, monitors, gaming consoles, and home theaters.
