       DP cable is also a high-definition output cable, the common interface is also a truth, from the different versions of the choice, DP version 1.1 to 1.4 different where, however, DP interface is also a different choice, DP is also a high-definition digital display interface standard, can be connected to computers and monitors, can also be connected to computers and home theater. Here's a simple break down what's changed over the years between the so-called DP lines and interfaces.


DP1.1 first  

       In terms of performance, DisplayPort1.1 supports up to 10.8Gb/S of transmission bandwidth, HDMI1.3 standard supports 10.2G/s bandwidth, and DisplayPort supports WQXGA plus (2560 x 1600), QXGA (2048 x 1536) The same resolution and 30/36bit (10/12bit per primary color) color depth, 1920 x 1200 resolution color support to 120/24bit, ultra-high bandwidth and resolution is fully adapted to the development of display devices.



        The total bandwidth was increased to 32.4Gbps (4.05GB/s), with each of the four channels allocated 8.1Gbps, a 50% increase over the previous DP1.2/1.2a and three times the 1.1 standard. Excluding all kinds of redundancy and loss, DP1.3 can provide an actual data transfer rate of up to 25.92Gbps (3.24GB/s), with a single data cable to handle lossless HD video and audio, and easily support 5120 x 28805K level of display devices.



        This DP standard update will undoubtedly inspire the upgrade of mobile devices again, and more user use scenarios will be stimulated. DisplayPort1.4 will support 8K resolution signal transmission and will be compatible with the USB Type-C interface. As can be seen from the technical parameters of this update, This time the eDP1.4a interface provides 4 HBR3 high-speed channels between the display adapter and the display, with a single channel bandwidth of 8.1Gbps, which can be operated independently or in pairs, and 4 channel theoretical bandwidth of 32.4Gbps, enough to support the 4K120Hz output in 10-bit color, or 8K60Hz Output.


       When viewed from the comparison between the DP line and the HDMI line, the role of different wire similar, mainly a high-definition for the direction of a study, so the yearning for HD is getting better and better.
