VESA has finalized DisplayPort 1.4 standard, compared to the current DisplayPort 1.3, the new standard supports VESA’s Display Stream Compression (DSC) version 1.2 technology. It also supports increased display resolutions to include 8Kp60Hz HDR deep color and 4Kp120Hz HDR deep color.

According to VESA, the use of video transport compression actually “...enhances the ability to take advantage of the USB Type-C connector….” This means that 8K video can be now be pushed across the DisplayPort or USB-C connector. If you are worried about the transport error, VESA claims that the DSC is lossless but in order to enhance its transport error resiliency, the DisplayPort 1.4 standard supports Forward Error Correction (FEC), which “...overlays the DSC 1.2 transport….”

The new standard has also been expanded to cover up to 32 audio channels, 1536kHz sample rate, and it covers “...all know audio formats.” VESA also highlighted the improved Multi-Stream Transport (MST) capability to enable the support of high-resolution, multiple-display setup, on a single display connector. VESA aims to address the growing needs of end-consumer for high-quality AV content.
