What Is a DisplayPort Cable?

DisplayPort (abbreviated as DP) is a digital video interface standard developed by the PC and Chip Manufacturers Alliance and standardized by the Video Electronics Standards Association (VESA). This interface is free of authentication and license fees. It is mainly used for connecting video sources to displays and other devices. It also supports audio, USB and other forms of data.

DisplayPort is the first display communication port that relies on packetized data transmission technology.

1. Protocol based on small packets

• Allows easy extension of the DisplayPort standard

• Allow multiple video streams in separate entities (in future versions)

2. Designed to support connections between internal chips

• Allows direct operation of display function options, removing the control loop of the display to produce a cheaper and thinner display.

• The goal is to replace the inside of the laptop panel with a unified link interface

  • DP1.4 has a bandwidth of up to 32.4Gbps and can support 8K 60Hz and 4K 120Hz HDR high resolution.

  • 8bit / 10bit data transmission

  • Open and extensible standards can accelerate adoption.

  • Supports 6, 8, 10, 12 and 16-bit color depth.

  • The full bandwidth of the cable is guaranteed to be 3 meters in length.

  • The effective transmission bandwidth of 1080p is guaranteed to be 5 meters.

  • Supports 128-bit
