Vesa announces displayport 2.0, far exceeding hdmi 2.1

When the HDMI 2.1 standard was announced, the question on the minds of tech enthusiasts was this: What will VESA's response be? We now know what their answer is, DisplayPort 2.0, a new standard that will offer more than 2X the bandwidth increase over DisplayPort 1.4 and that will probably come in late 2020.

DisplayPort 2.0 will offer 80 Gbps bandwidth

DisplayPort 2.0 is not a completely new standard, as it picks up much of what Intel's Thunderbolt 3 standards set.

DisplayPort 2.0 is using Thunderbolt 3's physical layer, allowing up to 80 Gbps of total bandwidth by using the standard one-way. Earlier this year, Intel released the Thunderbolt 3 standard to the industry as a royalty-free standard, allowing third parties not only to implement Thunderbolt 3 in their products without paying Intel, but also to allow third parties to reuse it to create other standards for the industry. Another example of a group redirecting Thunderbolt 3 is USB, which is using Thunderbolt to create USB4.

With this change, VESA is able to create a connectivity standard that can support 80 Gbps of bandwidth and operate over a DisplayPort or USB Type-C connection, exceeding the maximum bandwidth of 48 Gbps of HDMI 2.1.

Fortunately, DisplayPort 2.0 will retain compatibility with the existing DisplayPort standard, while some previously optional components of the older DisplayPort standards will be required with Displayport 2.0. Unfortunately, support for Variable Refresh Rate (VRR), better known to VESA as Adaptive-Sync, will continue to be an optional feature, unlike HDMI 2.0 displays.

Display Stream Compression (DSC) has become a mandatory part of Displayport 2.0, a feature that has only recently become part of DisplayPort 1.4 products, with AMD showing off the feature with its upcoming Navi graphics cards at E3.

VESA expects DisplayPort 2.0 devices to start arriving in late 2020, allowing for uncompressed 8K and higher resolutions, higher HDR levels with greater color depth, and a multitude of other display possibilities.
