HDMI stands for “High-Definition Multimedia Interface” which is an industry-standard audio/video interface for transmitting high-definition digital video and audio signals. HDMI was first introduced in 2002 and has since become the most popular interface for connecting digital devices such as televisions, projectors, DVD players, Blu-ray players, gaming consoles, and computers to display devices such as monitors and televisions.
HDMI supports several features such as high-definition video, multi-channel audio, 3D, and CEC (Consumer Electronics Control) which allows for one-touch control of multiple devices. It also supports HDCP (High-bandwidth Digital Content Protection) which is a content protection system designed to prevent the unauthorized copying of digital audio and video content.
HDMI supports resolutions up to 4K Ultra HD (3840×2160 pixels) and is backwards compatible with previous versions of HDMI and other video standards such as VGA, DVI, and S-video. HDMI can transmit video and audio over a single cable, eliminating the need for multiple cables to connect a device to a display.
HDMI cables come in different versions, such as HDMI 1.4 and HDMI 2.0. The latest version of HDMI is HDMI 2.1, which supports even higher resolutions, refresh rates, and dynamic HDR (High Dynamic Range) which allows for more vivid colors and brighter images.
