Video Electronics Standards Association (VESA) announced that the first video source and display devices supporting DisplayPort UHBR (Ultra-high Bit Rate) have been certified. To achieve that uber milestone—the highest data link rates supported by DisplayPort version 2.0—UHBR chipset source and display designs provided by AMD, MediaTek, and Realtek met the PHY, link, and interoperability testing requirements (outlined in the DisplayPort 2.0 Compliance Test Specification, or CTS).
The higher bandwidths enabled by UHBR provide uncompressed 8K at 60Hz HDR, 4K at 240Hz HDR, two 4K at 120Hz HDR, or four 4K at 60Hz HDR displays through a single cable.
And if you don’t blink, you can maybe see an engineering demonstration of a reference source and sink device setup from AMD and MediaTek operating at UHBR link rates, which will be showcased at the Display Week symposium and exhibition in San Jose, California, on May 10–12, 2022, at the VESA booth (#214) at the San Jose Convention Center.
Product developers that take advantage of the DisplayPort UHBR Certification Program can use the VESA-certified DisplayPort logo on their products and become reference devices for end-use product interoperability testing. Video source and display devices from AMD, MediaTek, and Realtek have already been certified, while more source and display devices from VESA member companies are undergoing certification. In addition, multiple UHBR-capable cable products have also completed certification and are commercially available.
