What is the DP interface
DP is a digital interface that can transmit audio and video at the same time as the HDMI interface, but unlike the HDMI interface, the DP interface is free of certification and free of license fees. The full name of DP is DisplayPort. It is a digital video interface developed by the Alliance of PC and Chip Manufacturers, and the Video Electronics Standards Association (VESA) has developed a standard digital video interface; it is mainly used to connect video sources and displays and other devices, and supports carrying audio, USB and Other forms of data

Standard DP interface and Mini DP interface diagram
Common DP interfaces include standard DP interface and Mini DP interface. The full name of the Mini DP interface is Mini DisplayPort, which was published by Apple on October 14, 2008; it is used in MacBook (replacing the previous Mini-DVI), MacBook Air (replacing the previous Micro-DVI) and MacBook Pro (replacing the previous DVI) in a notebook computer.
When using it, you must distinguish clearly which DP interface your device supports. Although both are DP interfaces, because the shape of the interface is different, the wire of the standard DP interface and the wire of the Mini DP interface are not available. Universal, only use the corresponding DP cable to connect to the display device correctly
What is the use of the DP interface?
The DP interface is the first display communication port that relies on packetized data transmission technology. It can be used for internal display connections or external display connections. The DisplayPort protocol is based on small data packets (called micro-messages) that can embed timer signals in the data stream, and can achieve higher resolution with a smaller number of pins.
If your monitor supports DP 1.2 Daisy-chaining, and your DP interface is also version 1.2 and supports MST (Multi-Stream Transport), then you can use a single DP to connect to multiple monitors
