What is the DP?
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 authorization. The full name of DP is DisplayPort, which is a digital video interface developed by the alliance of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA). other forms of data.
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 (replaces the previous Mini-DVI), MacBook Air (replaces the previous Micro-DVI), and MacBook Pro (replaces the previous Mini-DVI) in a notebook computer.
When using, be sure to distinguish which DP interface your device supports. Although both are DP interfaces, because the shapes of the interfaces are different, the cables of the standard DP interface and the cables of the Mini DP interface cannot be used. In general, only the corresponding DP cable can be used to connect to the display device correctly.
What is the use of the DP?
The DP interface is the first display communication port that relies on packetized data transmission technology, which can be used for both internal display connections and external display connections. The DisplayPort protocol is based on small data packets (called micro-packets) that can embed timer signals in the data stream, allowing for higher resolutions using fewer pins.
If your monitor supports DP 1.2 daisy-chaining (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.
