VESA has been released the DisplayPort 2.0 version in June 2019, DisplayPort 2.0 allows video bandwidth capacity to increase by up to 3X (max payload of 77.37Gbps). The new built-in features allow for enhanced user experience, increased flexibility, and increased power efficiency. The DisplayPort payload bandwidth is the efficient factoring of bandwidth in overhead coding. DisplayPort 2.0 has more robust coding compared to previous DP generations and allows network bandwidth capacity to increase by up to 3X compared to DisplayPort 1.4a.
DisplayPort 2.0 is the first major update to the DisplayPort specification since March 2016, offering up to a 3X boost in network bandwidth capacity compared to DisplayPort’s previous edition (DisplayPort 1.4a), as well as additional features to meet the potential performance requirements of conventional displays.
These include support for higher resolutions above 8 K resolutions, faster refresh rates and high dynamic range (HDR), increased support for various display setups, as well as enhanced user experience for Augmented/Virtual Reality (AR/VR) displays, including support for 4K-and-beyond VR Resolutions.
The advantage of DisplayPort 2.0 is it supports both the native DisplayPort connector and USB Type-C connector, which supports audio and video signal through DisplayPort Alt Mode. VESA also claims DisplayPort 2.0 is compatible with DisplayPort 1.4a.
DisplayPort 2.0 increased the bandwidth of video performance over a USB-C connector to simultaneously gain high-speed USB data transfer without losing display performance. DisplayPort 2.0 takes advantage of the Thunderbolt 3 interface to maintain the flexibility of the DisplayPort protocol to boost the data bandwidth.
DisplayPort 2.0 comes with a display stream data mapping protocol common to support single-stream transport and multi-stream transport, this will allow multi-stream transport support of DisplayPort 2.0 devices for a single DisplayPort port on the source device to drive multiple displays via dock station. The first product of DisplayPort 2.0 will be released in the market by late 2020.
The previous DisplayPort version, v1.4a, offered a maximum connection bandwidth of 32.4Gbps, with each of the four lanes operating at 8.1Gbps/lane. With 8b/10b channel coding, that’s equivalent to a maximum 25.92Gbps payload. DisplayPort 2.0 raises the maximum link rate to 20Gbps/lane and features more effective 128b/132b channel coding, offering a cumulative payload of 77.37Gbps – up to a triple improvement over DisplayPort 1.4a. This means that DisplayPort 2.0 is the first standard to support 8K resolution (7680 x 4320) at a refresh rate of 60Hz with a full-color resolution of 4:4:4 including 30-bits per pixel (bpp) for HDR-10.
Maximize the performance enabled by DisplayPort 2.0 through both native DisplayPort connector and USB-C connector via DisplayPort Alt Mode. USB-C allows you a single connector for USB data, video data, and power. USB-C requires a single USB Data, Video, and Power connector. When SuperSpeed USB data and video are required simultaneously, the dramatically improved data levels provided by DisplayPort 2.0 allow users the ability to provide both power and SuperSpeed USB data at the same time as super-high-resolution video.
DisplayPort 2.0 allows a number of high-performance configurations via the native DisplayPort connector or through USB-C as DisplayPort Alt Mode:
Single display resolutions
• One 16K (15360×8460) display @60Hz and 30 bpp 4:4:4 HDR (with DSC)
• One 10K (10240×4320) display @60Hz and 24 bpp 4:4:4 (no compression)
Dual display resolutions
• Two 8K (7680×4320) displays @120Hz and 30 bpp 4:4:4 HDR (with DSC)
• Two 4K (3840×2160) displays @144Hz and 24 bpp 4:4:4 (no compression)
Triple display resolutions
- Three 10K (10240×4320) displays @60Hz and 30 bpp 4:4:4 HDR (with DSC)
- Three 4K (3840×2160) displays @90Hz and 30 bpp 4:4:4 HDR (no compression)
By using only two-lane on the USB-C connector via DisplayPort Alternate Mode to allow for simultaneously SuperSpeed USB data and video, DisplayPort 2.0 can be enabled by following configurations:
• Three 4K (3840×2160) displays @144Hz and 30 bpp 4:4:4 HDR (with DSC)
• Two 4Kx4K (4096×4096) displays (for AR/VR headsets) @120Hz and 30 bpp 4:4:4 HDR (with DSC)
• Three QHD (2560×1440) @120Hz and 24 bpp 4:4:4 (no compression)
• One 8K (7680×4320) display @30Hz and 30 bpp 4:4:4 HDR (no compression)
