HDMI (High-Definition Multimedia Interface) is a digital audio/video interface used for transmitting high-quality uncompressed audio and video data between devices. The HDMI connector is a small, rectangular port used to connect various devices, such as TVs, monitors, projectors, and gaming consoles, to each other.
The HDMI connector has become a standard interface for high-definition audio and video transmissions, replacing older analog connections such as VGA, RCA, and component video. HDMI supports various video resolutions, including 720p, 1080p, 4K, and even 8K, as well as audio formats such as stereo, 5.1, 7.1, and Dolby Atmos.
The HDMI connector comes in different sizes and shapes, including the standard HDMI Type A, which is the most commonly used connector, and the smaller Type C (Mini-HDMI) and Type D (Micro-HDMI) connectors used for mobile devices and cameras. HDMI cables are also available in different lengths and versions, with the latest version supporting features such as HDR (High Dynamic Range) and variable refresh rate.
