Organization VESA (Organization Video Electronics Standards Association) released the specifications interface DisplayPort version 2.1. The updated standard does not provide for an increase in bandwidth relative to DisplayPort 2.0, which allows you to display an image with a resolution of up to 10240 × 4320 pixels at 60 Hz without compression. The main innovations lie in tighter integration with USB4 and improved signal transmission reliability.
The good news is that DisplayPort 2.1 isn’t just backwards compatible with the previous version of the interface. Through the efforts of VESA and its partners, all DisplayPort 2.0 products “have already been certified to the more stringent DisplayPort 2.1 specification.” This means that any DisplayPort 2.0-certified GPU, docking station, monitor, and cable is fully compatible with version 2.1.
The DisplayPort 2.1 standard introduced a new bandwidth management feature “to allow DisplayPort tunneling to more efficiently coexist with other USB4 I/O data traffic.” In addition, DP40 (40 Gb/s) cables can now exceed two meters, and DP80 (80 Gb/s) cables can now exceed one meter.
It is worth adding that the preparations for the release of the DisplayPort 2.1 standard became known last week. It will be supported by Radeon RX 7000 graphics cards based on 3rd generation AMD RDNA GPUs, which will officially debut on November 3rd. At the same time, Nvidia limited its new generation of video cards to the DisplayPort 1.4a interface.
