The interface originally developed for high-definition televisions that is also widely used to connect audio and video devices in computers is called HDMI, which stands for High-Definition Multimedia Interface.

HDMI was designed to transmit both high-definition video and audio signals through a single cable, making it convenient for users to connect various devices, such as televisions, monitors, projectors, and audio receivers, without the need for multiple cords.
