HDMI HD cable as a kind of smart TV and computer signal transmission line will be the content of the computer through the HDMI cable to the smart TV.

HDMI cable is an acronym for High-Definition Multimedia Interface, which is capable of transmitting uncompressed high-definition video and multi-channel audio data at up to 5Gbps, without the need for digital-to-analog or analog-to-digital conversion prior to the signal being transmitted, thus guaranteeing the highest possible quality of audio and video signal transmission.

The HDMI cable supports 5Gbps data transfer rate and can transfer up to 30 meters, which is sufficient for a 1080p video and an 8-channel audio signal. And since a 1080p video and an 8-channel audio signal requires less than 4GB/s, the HDMI cable has a lot of headroom left over. This allows it to connect a DVD player, receiver and PRR separately with one cable. In addition, HDMI supports EDID, DDC2B, so devices with HDMI have the characteristics of "Plug and Play", the signal source and the display device will automatically carry out "negotiation", automatically selecting the most suitable signal. "The HDMI interface is designed to work seamlessly with all of the latest video and audio technologies, including HDMI?, HDMI?, and HDMI?.
