The Video Electronics Standards Association (VESA) publishes the DisplayPort 2.0 standard. The successor to DisplayPort 1.4 is expected to provide a significantly increased data rate, enabling resolutions of 16K at 60 Hertz.

Increased data rate for higher resolutions

DisplayPort 1.4 offers a 32.4 Gbps bit rate, which increases to 80 Gbps with DisplayPort 2.0, providing 20 Gbps per lane.

The interface standard uses Thunderbolt 3’s physical interface and 128b/130b encoding, allowing data rates of 77.37 Gbps. By comparison, DisplayPort 1.4 achieves data rates of up to 25.92 Gbps.

16K resolution with compression only

The significantly higher data rates allow the interface to transfer higher resolutions. 8K resolution (7,680 x 4,320 pixels) should be possible with 60 Hertz at full 4:4:4 color resolution and 10 bits per color channel. Thus, HDR10 can also be used at high resolution, without HDR the interface transmits a maximum of 10K at 60 Hz.

The new standard also supports display stream compression technology, which even achieves 16K resolution (15,360 x 8,460 pixels). DisplayPort 2.0 also includes the Screen Data Mapping Protocol display, which includes technologies such as single-stream and multi-stream. The latter realized the series connection several monitors at one output.

DisplayPort 2.0 will be released in late 2020

The plug is identical to that of DisplayPort 1.4, optionally manufacturers can also use the new interface standard via USB-C plug. First devices with DisplayPort 2.0 are expected to be released in late 2020.
