VESA Publishes DisplayPort 1.4 With Support for 8K, DSC 1.2, and USB Type-C
The Video Electronics Standards Association (VESA) has published the first major update to DisplayPort (DP) since the release of version 1.3 in September 2014.
DisplayPort 1.4 comes with an array of new features as well as retains capabilities of the standard’s prior incarnations. The most highlighted feature making it to the newest version is the support for VESA’s Display Stream Compression (DSC) technology. VESA deems DSC version 1.2 “visually lossless, ” while enabling up to 3:1 compression ratio.
In addition to that, DP 1.4 is compatible with Intel Thunderbolt and the new reversible USB Type-C interface, which means you’ll be able to connect next-gen monitors to your system via a single, tiny cable.
The latest version also features enhanced display resolution facilitating 8K (7680×4320)@60Hz in both high dynamic range and standard modes. 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.
Last but not least, VESA AdaptiveSync standard is also part of the embedded DisplayPort 1.4, though it’s not clear if it is mandatory in the new standard or not.
