The Video Electronics Standards Association (VESA®) announced that the first video source and display devices supporting DisplayPort UHBR (Ultra-high Bit Rate) – the higher data link rates supported by the DisplayPort standard version 2.0 – have completed certification through the DisplayPort UHBR Certification Program.

Figure 1 shows that UHBR chipset reference source and display designs provided by AMD, MediaTek and Realtek successfully met the PHY, link and interoperability testing requirements outlined in the DisplayPort 2.0 Compliance Test Specification (CTS).

The higher bandwidths enabled by UHBR support a variety of use cases such as uncompressed 8K 60Hz HDR, 4K 240Hz HDR, two 4K 120Hz HDR or four 4K 60Hz HDR displays through a single cable.

VESA also announced that qualified VESA DisplayPort Authorized Test Centres (ATCs) are ready to begin testing and certification of UHBR end-products using approved test equipment and reference sink and source devices for interoperability testing. [1]

"We are very proud to be the first DisplayPort adopter to achieve DisplayPort UHBR certification for a sink device," said Vince Hu, corporate vice president and general manager, Compute Business Unit, MediaTek Inc.

"With the features that DisplayPort 2.0 brings to the table, we are able to develop advanced, robust technologies that system manufacturers can leverage to revolutionize the consumer's highest quality visual experience.

VESA requires very stringent testing before certification can be granted, making MediaTek's achievement even more impressive. We are honoured to play a critical role in VESA's efforts to ensure interoperability and deliver industry leading products to market." [2]

We haven’t seen DisplayPort 2.0 in action yet but that may soon change, as AMD, MediaTek and Realtek say their devices are DP2.0 certified. At AMD it is Ryzen 6000 series processors, at Realtek – network solutions for Tx and Rx partners; as for Mediatek, the company did not name which device or solution it meant, vaguely calling it a “sink device”.

It is unknown at this time what to expect for commercial display models with DisplayPort 2.0. It is reported that the demonstration stands with AMD and MediaTek devices can be seen this week, at the Display Week event in San Jose, California.
