The HDMI cable is an abbreviation for high-definition multimedia interface cable. It can transmit uncompressed high-definition video and multi-channel audio data with high quality. The maximum data transmission speed is 5Gbps. At the same time, there is no need for digital / analog or analog / digital conversion before signal transmission, which can ensure the highest quality audio and video signal transmission.

The HDMI cable supports a data transmission rate of 5Gbps, and can transmit 30 meters at the farthest, which is enough to cope with a 1080p video and an 8-channel audio signal. And because a 1080p video and an 8-channel audio signal require less than 4GB / s, there is still a lot of HDMI cable. This allows it to connect the DVD player, receiver and PRR with a cable. In addition, HDMI supports EDID and DDC2B, so devices with HDMI have the characteristics of "plug and play". The source and display device will automatically "negotiate" to automatically select the most suitable video / audio format.

HDMI, or high-definition multimedia interface, is a proprietary audio / video interface. It can transmit high-definition video and audio between two electronic devices through a cable.

Over the years, HDMI has taken root in the public domain. As a single-cable solution to meet the audio-visual needs of every consumer, HDMI provides great convenience, it eliminates audio and video functions (such as audio jacks and VGA), without the need to use two separate cables.

You may not have noticed, but HDMI is currently the most commonly used cable in the home. It connects devices such as digital TVs, DVD players, Blu-ray players, Xbox game consoles, cable TV boxes, Playstation game consoles, and Apple TVs to TV sets. Audio cables such as mixers, recording systems, and speakers also use this cable.

Modern notebook computers and personal computers have recently been designed with ports compatible with HDMI cables. With this innovation, these devices can now be easily connected to projectors, commercial screens and multi-screen video walls. HDMI cables will definitely contribute to the revolution in businesses and business sectors-education, business presentations, digital signage and retail displays, among other applications.
