The Displayport cable is also a high-definition output cable. From different displayport versions, the DP cable version 1.1 to 1.4 is different. However, the DP interface is also a different choice. Displayport interface is also a high-definition digital display. DP Cable can be used for connecting computers and monitors, as well as computers and home theaters. So let’s see decomposition of DP cable and interface changes in the past few years.
Standard of Displayport 1.1
In terms of performance, DisplayPort 1.1 supports a maximum transmission bandwidth of 10.8Gb/s, and HDMI 1.3 standard can support a bandwidth of 10.2G/s. In addition, DisplayPort can support WQXGA+ (2560×1600), QXGA (2048×1536), etc. Resolution and color depth of 30/36bit (10/12bit per primary color), 1920×1200 resolution color support to 120/24Bit, ultra-high bandwidth and resolution is enough to adapt to the development of display devices.
Standard of Displayport 1.3
The total bandwidth has been increased to 32.4 Gbps (4.05 GB/s), and each of the four channels is allocated 8.1 Gbps, which is 50% larger than the previous DP1.2/1.2a and three times than standard of the 1.1 version. After eliminating various redundancy and loss, the DP 1.3 actual data transmission rate can provide as high as 25.92Gbps (3.24GB/s). It can be used for lossless HD video & audio with one data cable, and easily support 5120×2880K Level display device.
Standard of Displayport 1.4
This update of DP standard will undoubtedly trigger the upgrade of mobile devices again, and more user usage scenarios will be stimulated. DisplayPort 1.4 will support 8K resolution signal transmission and is compatible with USB Type-C interface. As can be seen from the technical parameters of this update, this eDP1.4a interface provides four HBR3 high-speed channels between the display adapter and the display, and the single-channel bandwidth reaches 8.1 Gbps. These channels can be operated independently or in pairs. The 4 channel theoretical bandwidth is 32.4Gbps, which is enough to support 4K120Hz output of 10-bit color, and can also support 8K60Hz output.
