DVI is based on the Transition Minimized Differential Signaling (TMDS) technology to transmit digital signals, and uses Differential signals to transmit data after DC balance. Compared with LVDS(low voltage differential signal) and TTL(through lens), it has better electromagnetic compatibility performance, and can be used to realize long-distance and high-quality digital signal transmission with low-cost special cable. USB, the Universal Serial Bus, is a new interface technology that has been widely used in the PC field in recent years. It has been broadly used in various external devices. Hdmi connector is the auxiliary accessories of HDMI interface. It is mainly used to connect the monitor and the computer host.
