DisplayPort 1.4 To Support 8K Displays over USB-C, 4K@120 Hz, 32 Audio Channels

Just as 4K UHD televisions are getting more affordable with prices ever closer to their Full HD equivalent, the Video Electronics Standards Association (VESA) has published DisplayPort 1.4 specifications with support for 8K QUHD (7680 x 4320) resolution, High Dynamic Range (HDR), video compression and more.

DisplayPort_1.4_8K_QUHDSome of the key enhancements or new features of the new specifications include:

  • Up to 8Kp60Hz HDR deep color and 4Kp120Hz HDR deep color
  • Display Stream Compression (DSC) – DSC 1.2 natively supports YCbCr 4:2:0 and 4:2:2 coding, and offers nearly lossless 3:1 compression ratio
  • 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 – DP 1.4 supports up to 32 audio channels, 1536kHz sample rate, and inclusion of all known audio formats.

It will take a few years before 8K and DP 1.4 start to take off. 8K televisions have just launched with hefty prices including Sharp LV-85001 for around $125,000, and content is basically non-existent with one the first 8K broadcast likely to be Tokyo’s 2020 Olympics four years from now.
