The dp cable is a digital signal cable for high-definition digital display connecting a computer and a monitor, or a computer and a home theater, and supports ultra-high resolution and high refresh rate transmission. Usually connected to the DisplayPort interface.

DisplayPort allows audio and video signals to be transmitted on the same cable and supports a variety of high-quality digital audio. More functions can be realized on one cable. In addition to the four main transmission channels, DisplayPort also provides a powerful auxiliary channel.

The transmission bandwidth of the auxiliary channel is 1Mbps, and the maximum delay is only 500μs. It can be directly used as a transmission channel for low-bandwidth data such as voice and video, and can also be used for game control without delay. Therefore, DisplayPort can achieve maximum integration and control of peripheral devices.

DisplayPort is a display interface issued by the Video Electronics Standards Association (VESA). As the successor to DVI, DisplayPort will add support for high-definition audio signal transmission while transmitting video signals, while supporting higher resolution and refresh rate.

It can support single-channel, one-way, four-line connection, data transmission rate 10.8Gbps, enough to transmit uncompressed video and related audio, and also supports 1Mbps bidirectional auxiliary channel for device control, in addition to support 8 And 10-bit color. In data transmission, DisplayPort uses the "micro-packetised" format.
