Latest DisplayPort specification provides greater alignment with USB Type-C and USB4;

BEAVERTON, Ore. – October 17, 2022 – The Video Electronics Standards Association (VESA®) announced contiguous that it has released DisplayPort 2.1, the latest mentation of the DisplayPort specification, which is backward compatible with and supersedes the erstwhile mentation of DisplayPort (DisplayPort 2.0). VESA has been moving intimately with subordinate companies to guarantee that products supporting DisplayPort 2.0 would really conscionable the newer, much demanding DisplayPort 2.1 spec. Due to this effort, each antecedently certified DisplayPort 2.0 products including UHBR (Ultra-high Bit Rate) susceptible products – whether GPUs, docking presumption chips, show scalar chips, PHY repeater chips specified arsenic re-timers, oregon DP40/DP80 cables (including some passive and active, and utilizing full-size DisplayPort, Mini DisplayPort oregon USB Type-C connectors) – person already been certified to the stricter DisplayPort 2.1 spec.

Achieving a robust, end-to-end idiosyncratic ocular acquisition remains the utmost precedence for VESA’s DisplayPort specification, whether crossed a autochthonal DisplayPort cable, via DisplayPort Alt Mode (DisplayPort implicit the USB Type-C connector), oregon tunneled done the USB4 link. As such, DisplayPort 2.1 has tightened its alignment with the USB Type-C specification arsenic good arsenic the USB4 PHY specification to facilitate a communal PHY servicing some DisplayPort and USB4. In addition, DisplayPort 2.1 has added a caller DisplayPort bandwidth absorption diagnostic to alteration DisplayPort tunneling to coexist with different I/O information postulation much efficiently implicit the USB4 link. This accrued ratio is connected apical of mandated enactment for VESA’s visually lossless Display Stream Compression (DSC) codec and VESA’s Panel Replay capability. DSC bitstream enactment tin trim DisplayPort transport bandwidth successful excess of 67 percent without ocular artifacts, portion VESA’s Panel Replay capableness tin trim DisplayPort tunneling packet transport bandwidth successful excess of 99 percent erstwhile Panel Replay cognition is taking place.

“Achieving greater alignment betwixt DisplayPort and USB connected a communal PHY has been a peculiarly important effort wrong VESA fixed the important overlap successful usage lawsuit models betwixt the DisplayPort and USB4 ecosystems. DisplayPort 2.1 brings DisplayPort into convergence with USB4 PHY specifications to guarantee the highest video show crossed a wide scope of user products. Display transport done DisplayPort, with its higher spot rates and proven ocular prime of DSC compression adjacent for HDR content, offers ample bandwidth for the needs of virtually each applicable application. Features specified arsenic driving aggregate displays implicit a azygous cable, oregon enabling aggregate functions connected a azygous larboard similar video, powerfulness and information transfer, nary longer necessitate immoderate compromise successful video format choice. The precocious capabilities of the DisplayPort video interface are enabled by the invaluable contributions by our much than 300 subordinate companies from crossed the electronics ecosystem.”

— stated Alan Kobayashi, VESA Board Chair and VESA DisplayPort Task Group Chair.

DisplayPort 2.1 has besides updated the DisplayPort cablegram specification to supply greater robustness and enhancements to full-size and Mini DisplayPort cablegram configurations that alteration improved connectivity and longer cablegram lengths (beyond 2 meters for DP40 cables and beyond 1 metre for DP80 cables) without diminishing UHBR performance. VESA certified DP40 cables enactment up to the UHBR10 nexus complaint (10 Gbps), with 4 lanes, providing a maximum throughput of 40 Gbps, portion VESA certified DP80 cables enactment up to the UHBR20 nexus complaint (20 Gbps), with 4 lanes, providing a maximum throughput of 80 Gbps.

“For each of our standards including DisplayPort, VESA has invested important resources successful investigating and auditing procedures, including interoperability investigating of products incorporating VESA specifications. This is to guarantee that products that are introduced to marketplace that assertion enactment of VESA’s standards conscionable the high-quality benchmarks that we person established. VESA continues to analyse and make caller procedures to amended our auditing process successful bid to guarantee robust implementation of prime products supporting DisplayPort and different VESA specs successful the market. Thanks to the contributions by trial instrumentality vendors, VESA has a coagulated trial infrastructure successful spot to enactment wider investigating and deployment of DisplayPort 2.1 certified devices successful the marketplace.”

— stated James Choate, compliance programme manager for VESA.
