HDMI (High Definition Multimedia Interface) is a digital audio and video transmission standard widely used in the field of consumer electronics. It simultaneously transmits high-definition video and multi-channel audio signals through a single cable, replacing the traditional multi cable connection method and greatly simplifying the connection process between home theaters, game consoles, computers, and display devices.
Since its launch in 2002, HDMI has undergone multiple upgrades. The latest version (such as HDMI 2.1) supports 8K resolution, 120Hz refresh rate, dynamic HDR, and variable refresh rate (VRR), meeting the needs of 4K gaming and ultra high definition film and television. Its plug and play features and high bandwidth design (up to 48Gbps) ensure the stability of uncompressed signals and lossless transmission of image quality.
Nowadays, HDMI has become a standard interface for televisions, projectors, graphics cards, and gaming consoles, driving the continuous evolution of large screen entertainment experiences.
