What is the HDMI cable used for?

HDMI is the abbreviation of High Definition Multimedia Interface cable, which can transmit uncompressed high-definition video and multi-channel audio data with high quality, and the maximum data transmission speed is 5Gbps. At the same time, there is no need to perform digital/analog or analog/digital conversion before signal transmission, which can ensure the highest quality audio and video signal transmission.
It can connect DVD players, receivers and PRRs with one cable. In addition, HDMI supports EDID and DDC2B, so devices with HDMI have the characteristics of "plug and play", and the signal source and display device will automatically "negotiate" and automatically select the most suitable video/audio format.
