The VESA, short for Video Electronics Standards Association, has now released the final specification for DisplayPort 1.4 standard bringing support for 8K HDR video at 60Hz and 4K HDR video at 120Hz as well as few other feature improvements.

The VESA standard body has now finalized the specification for the DisplayPort 1.4 standard which is the first major update to DisplayPort standard since the finalization of the DisplayPort 1.3 back in September 2014.

While DisplayPort 1.3 already allowed both video and data to be pushed over USB Type-C and Thunderbolt interfaces, the new DisplayPort 1.4 specification brings SuperSpeed USB (USB 3.0) to be paired up with high-definition video, allowing it provide increased resolution of 8K HDR video (7680x4320) at 60Hz or 4K HDR (3840x2160) at 120Hz.

The more important new feature in DisplayPort 1.4 specification is the Display Stream Compression 1.2, which, according to VESA, should provide "visually lossless" video stream by using 3:1 compression. In combination with the new Forward Error Correction features which in combination with the DSC 1.2 on external monitor, should allow the use of DSC on external monitor and deal with any signal corruption that could show up.

The new DisplayPort 1.4 specification also brings HDR meta transport, which uses the "secondary data packet" transport in the DisplayPort standard to provide support for CTA 861.3 standard. This is useful in DisplayPort to HDMI 2.0 protocol conversion and also brings support for future dynamic HDR standards.

VESA also mentioned an expanded audio transport in the new DisplayPort 1.4 standard which now includes support for 32 audio channels, 1536kHz sample rate and all known audio formats.

Unfortunately, it will take some time before wee see the integration of the DisplayPort 1.4 standard in actual products as we are yet to see some devices with support for DisplayPort 1.3 standard, which is now well over a year old.
