VESA DisplayPort Standard Version 1.4 Released With Enhancements


The Video Electronics Standards Association (VESA) has published version 1.4 of the DisplayPort (DP) audio/video standard.

The first major update to DisplayPort since version 1.3 is also the first DP standard to take advantage of VESA's Display Stream Compression (DSC) technology. DSC version 1.2 transport enables up to 3:1 compression ratio and has been deemed, through VESA membership testing, to be visually lossless.

DisplayPort is a packet-based, extensible protocol for transporting video and audio data. Initially introduced as a new external interface, its flexibility has enabled its adaptation to embedded displays and incorporation into other connectors like the new reversible USB Type-C interface and Thunderbolt. Its Multi-Stream Transport (MST) capability enables high-resolution support of multiple monitors on a single display interface.

In September 2014, VESA published DP 1.3, which increased the maximum link bandwidth to 32.4 Gbps, with each of four lanes running at a link rate of 8.1 Gbps/lane, a 50-percent increase over the previous DP 1.2a specification. DP 1.3 added extra protocol flexibility to enable more seamless operation over the USB Type-C connector in the form of the DisplayPort Alt Mode. The increased link rate increased the uncompressed display resolution support up to 5K x 3K (5120x2880), and also upped the MST resolution, enabling simultaneous use of two 4K UHD monitors, each with a pixel resolution of 3840x2160, when using VESA Coordinated Video Timing.

DP 1.4 further builds on the capabilities of the standard's prior incarnations. The use of video transport compression enhances the ability to take advantage of the USB Type-C connector, enabling both high-definition video and SuperSpeed USB, while also facilitating High Dynamic Range (HDR) and 8K video across the DisplayPort or USB-C connector. Examples of increased display resolution with the new standard include 8Kp60Hz HDR deep color and 4Kp120Hz HDR deep color. Other key new features include:

  • Forward Error Correction - FEC, which overlays the DSC 1.2 transport, addresses the transport error resiliency needed for compressed video transport to external displays.
  • HDR meta transport - HDR meta transport uses the "secondary data packet" transport inherent in the DisplayPort standard to provide support for the current CTA 861.3 standard, which is useful for DP to HDMI 2.0a protocol conversion, among other examples. It also offers a flexible metadata packet transport to support future dynamic HDR standards.
  • Expanded audio transport - This spec extension covers capabilities such as 32 audio channels, 1536kHz sample rate, and inclusion of all known audio formats.
