DP interface supports single-channel, one-way, and four-line connections, and the data transmission rate is 10.8Gbps, which is enough to transmit uncompressed video and related audio. At the same time, it also supports 1Mbps two-way auxiliary channel for device control. In addition, the DP interface also supports 8-bit and 10-bit color.
