Introduction to DP2.0

The full name of DP2.0 is DisplayPort2.0. It was released by the management VESA Video Electronics Standards Association in 2019. It is a digital audio and video data exchange protocol. It is mainly used for the connection between video sources and monitors and other devices. and other forms of data.

DP2.0 interface appearance

Thanks to the support of USB-IF, the DP Alt mode can be seamlessly connected with the USB4 specification, so the DP2.0 interface can have two forms, DP and USB Type-C, which means that the DP2.0 interface can be used with our common Type-C. -C interface and Thunderbolt 3 interface have the same appearance. In order to distinguish it from the ordinary Type-C interface, DP2.0 will add a DP logo to the interface, just like the Thunderbolt 3 interface with the Thunderbolt logo next to it, users can more intuitively identify the DP2.0 interface.

Note that although the DP2.0 interface has the same appearance as the Type-C interface and the Thunderbolt 3 interface, the three protocols are different, and the functions are very different. As for the interface difference between the DP2.0, Type-C and Thunderbolt 3, we will follow Chapters will give details.

The DP2.0 protocol supports a maximum resolution of 16K (15360*8460) and an original bandwidth of 80 Gbps, which is 2.5 times the bandwidth of DP1.4; at the same time, DP2.0 uses the latest encoding protocol, the new standard bandwidth utilization As high as 97%, the peak effective bandwidth is 77.4 Gbps, which is about 3 times the effective bandwidth of DP1.4.

The differences between DP2.0 and 1.4 are basically mentioned above, mainly the differences in physical interfaces and bandwidth capabilities.

Physical interface: DP2.0 has two physical shapes, DisplayPort and USB Type-C, while DP1.4 is still the traditional DisplayPort interface (as shown in the figure above).

Bandwidth capability: DP2.0 has a bandwidth of 80Gbps and supports 16K@60Hz, 8K@120Hz and 4K@144Hz; DP1.4 has a bandwidth of 32.4Gbps and supports 8K@30Hz and 4K@120Hz.

DP2.0 application

The powerful bandwidth capability of DP2.0 allows it to meet 8k high-definition resolution without any compression, and even in a short-distance use environment, it can meet 16K ultra-high resolution for a single display device and three display devices. At the same time, the 10K@60Hz HDR ultra-clear display mode provides the basis for the high-fidelity display of game animations.

Regarding the application of DP2.0, there are currently very few 8K video resources and monitors that support resolutions above 8K, but the management VESA is promoting the DP2.0 standard. With the development of DP2.0 interface monitors and the improvement of supporting systems, DP2.0. 0 products are expected to appear in the second half of this year, and Lvlian will also bring relevant peripherals of the DP2.0 standard to serve everyone.
