First Devices Supporting DisplayPort UHBR Certified By DisplayPort UHBR Certification Program
The Video Electronics Standards Association (VESA) has 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. To achieve this important milestone, 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 today that qualified VESA DisplayPort Authorized Test Centers (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.
An engineering demonstration of a reference source and sink device setup from AMD and MediaTek operating at UHBR link rates will be showcased at the Display Week Symposium and Exhibition in San Jose, Calif., on May 10-12, 2022 at VESA booth #214 at the San Jose Convention Center.
“These latest developments in the DisplayPort UHBR Certification Program represent major steps forward in the roll-out of the DisplayPort UHBR ecosystem for new video, display and cable products supporting higher resolutions and refresh rates,” stated James Choate, compliance program manager for VESA. “Certification of UHBR reference devices must undergo rigorous testing to ensure they meet the requirements outlined in the DisplayPort 2.0 CTS. We’re excited to announce that a set of reference silicon has been verified to meet the requirements of the DisplayPort 2.0 spec through our certification program. VESA now has the testing infrastructure in place to evaluate and certify OEM end products, and we are ready to work with the ecosystem to bring next-generation DisplayPort chipsets and IP to market.”
Product developers who take advantage of the DisplayPort UHBR Certification Program gain the ability to 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.
