VESA Certified DisplayPort UHBR products are ensured to sustain the higher bit rates advocated by DisplayPort version 2.0 standards VESA also introduced VESA certified DP40 and DP80 UHBR cables, which assure display connectivity and operation at the most elevated implementation levels presented with DisplayPort 2.0. VESA certified DP40 cables must endow up to the UHBR10 link rate (10 Gigabits per second or Gbps) determined by DisplayPort 2.0, and support the complete four-lane operation, delivering a total throughput of 40 Gbps. VESA certified DP80 cables must support up to the UHBR20 link rate (20 Gbps) specified by DisplayPort 2.0, with four lanes, supplying a maximum throughput of 80 Gbps. VESA certified DP80 cables would also support the UHBR13.5 link rate (13.5 Gbps), also represented by DisplayPort 2.0. Multiple video source and display devices are currently experiencing testing in the DisplayPort UHBR Certification Program and should finish early certification very soon. Numerous DP40 and DP80 cables using enhanced full-sized DisplayPort and Mini DisplayPort connectors have passed certification and are in manufacturing. Vendors presently offering VESA certified DP40 and DP80 cables include Accell, BizLink, and WIZEN, with additional cables experiencing certification and anticipated to reach the market shortly. DP40 and DP80 cables are available in full-size and Mini DisplayPort cable configurations. They are backward compatible with products sponsoring DisplayPort link rates formerly described and now in use, including RBR (Reduced Bit Rate), HBR (High Bit Rate), HBR2, and HBR3. For DisplayPort Alt Mode (DisplayPort over the USB Type-C connector), passive USB-C cables endorse UHBR bit rate speeds. In contrast, USB Type-C to DisplayPort converter cables certified by VESA to complete UHBR speed requirements will soon be available. No matter how high the performance of your graphics card and monitor are, the resulting image quality can still be limited by the cable used to connect those devices. Thanks to improvements in both the DisplayPort connector and cable design, the new VESA certified DP40 and DP80 UHBR cables enable consumers to get the highest performance possible from their VESA certified devices. These new cables are backed by VESA’s UHBR Certification Program, which provides added assurance that if your cable has the DP40 or DP80 logo from VESA, it will meet the specs for the highest data rates supported by current and future products certified by VESA. — James Choate, compliance program manager, VESA UHBR device testing is currently available at DisplayPort ATCs, such as Allion Labs and Granite River Labs (GRL).
