What does a high definition multimedia interface (HDMI) primarily carry?

A high definition multimedia interface (HDMI) primarily carries audio and video signals. HDMI is designed to transmit both high-quality digital video and audio over a single cable. This capability makes it highly beneficial for connecting devices like televisions, computers, and gaming consoles, ensuring that users receive a synchronized multi-channel audio experience alongside high-definition video output.

The design of HDMI supports various video resolutions and audio formats, which includes everything from standard definition up to 4K and beyond, as well as multiple audio channels, making it a versatile choice for multimedia connectivity. By combining audio and video into one cable, HDMI reduces clutter while providing a seamless experience for users who require high fidelity in both sound and picture quality.
