Vesa, Displayport 2.1 사양 출시
Latest DisplayPort specification provides greater alignment with USB Type-C and USB4; adds new features for more efficient DisplayPort tunneling over USB4BEAVERTON, Ore. – October 17, 2022 – The Video Electronics Standards Association (VESA®) announced today that it has released DisplayPort 2.1, the latest version of the DisplayPort specification, which is backward compatible with and supersedes the previous version of DisplayPort (DisplayPort 2.0).
Vesa, Displayport 2.1 사양 출시
VESA has been working closely with member companies to ensure that products supporting DisplayPort 2.0 would actually meet the newer, more demanding DisplayPort 2.1 spec. Due to this effort, all previously certified DisplayPort 2.0 products including UHBR (Ultra-high Bit Rate) capable products – whether GPUs, docking station chips, monitor scalar chips, PHY repeater chips such as re-timers, or DP40/DP80 cables (including both passive and active, and using full-size DisplayPort, Mini DisplayPort or USB Type-C connectors) – have already been certified to the stricter DisplayPort 2.1 spec.
Achieving a robust, end-to-end user visual experience remains the utmost priority for VESA’s DisplayPort specification, whether across a native DisplayPort cable, via DisplayPort Alt Mode (DisplayPort over the USB Type-C connector), or tunneled through the USB4 link. As such, DisplayPort 2.1 has tightened its alignment with the USB Type-C specification as well as the USB4 PHY specification to facilitate a common PHY servicing both DisplayPort and USB4. In addition, DisplayPort 2.1 has added a new DisplayPort bandwidth management feature to enable DisplayPort tunneling to coexist with other I/O data traffic more efficiently over the USB4 link. This increased efficiency is on top of mandated support for VESA’s visually lossless Display Stream Compression (DSC) codec and VESA’s Panel Replay capability. DSC bitstream support can reduce DisplayPort transport bandwidth in excess of 67 percent without visual artifacts, while VESA’s Panel Replay capability can reduce DisplayPort tunneling packet transport bandwidth in excess of 99 percent when Panel Replay operation is taking place.
“Achieving greater alignment between DisplayPort and USB on a common PHY has been a particularly important effort within VESA given the significant overlap in use case models between the DisplayPort and USB4 ecosystems,” stated Alan Kobayashi, VESA Board Chair and VESA DisplayPort Task Group Chair. “DisplayPort 2.1 brings DisplayPort into convergence with USB4 PHY specifications to ensure the highest video performance across a broad range of consumer products. Display transport through DisplayPort, with its higher bit rates and proven visual quality of DSC compression even for HDR content, offers ample bandwidth for the needs of virtually every practical application. Features such as driving multiple displays over a single cable, or enabling multiple functions on a single port like video, power and data transfer, no longer require any compromise in video format choice. The advanced capabilities of the DisplayPort video interface are enabled by the invaluable contributions by our more than 300 member companies from across the electronics ecosystem.”

DisplayPort 2.1은 또한 DisplayPort 케이블 사양을 업데이트하여 풀사이즈 및 Mini DisplayPort 케이블 구성에 대한 더 큰 견고성과 향상된 기능을 제공하여 UHBR 성능 저하 없이 향상된 연결성과 더 긴 케이블 길이(DP40 케이블의 경우 2미터 이상, DP80 케이블의 경우 1미터 이상)를 가능하게 합니다. VESA 인증 DP40 케이블은 4개의 레인으로 최대 UHBR10 링크 속도(10Gbps)를 지원하여 최대 40Gbps의 처리량을 제공하는 반면, VESA 인증 DP80 케이블은 4개의 레인으로 최대 UHBR20 링크 속도(20Gbps)를 지원하여 최대 80Gbps의 처리량을 제공합니다.
“For all of our standards including DisplayPort, VESA has invested significant resources in testing and auditing procedures, including interoperability testing of products incorporating VESA specifications. This is to ensure that products that are introduced to market that claim support of VESA’s standards meet the high-quality benchmarks that we have established,” stated James Choate, compliance program manager for VESA. “VESA continues to investigate and develop new procedures to improve our auditing process in order to ensure robust implementation of quality products supporting DisplayPort and other VESA specs in the market. Thanks to the contributions by test equipment vendors, VESA has a solid test infrastructure in place to support wider testing and deployment of DisplayPort 2.1 certified devices in the marketplace.”
