On March 8, 2023, Liangang Optoelectronic Technology Co., Ltd. officially obtained the DP2.1 certification report of VESA Association

Officials say VESA has been working closely with member companies to ensure that DisplayPort 2.0 enabled products truly meet the newer and more demanding DisplayPort 2.1 specification. As a result of this effort, all previously certified DisplayPort 2.0 products, Including products that support UHBR (ultra high bit rate) -- whether it's Gpus, docking chips, monitor scalar chips, PHY repeater chips (such as retimer) or DP40 / DP80 cables (both passive and active, and using full size DisplayPort, Mini DisplayPort or USB Type-C interface) -- certified to the more stringent DisplayPort 2.1 specification.

Achieving a powerful end-to-end user visual experience remains a top priority for VESA's DisplayPort specification, Whether through the native DisplayPort cable, through the DisplayPort Alt mode (DisplayPort via the USB Type-C connector), or through the USB4 link tunnel. As a result, DisplayPort 2.1 reinforces consistency with the USB Type-C specification as well as the USB4 PHY specification to facilitate a common PHY that serves DisplayPort and USB4. In addition, DisplayPort 2.1 adds a new DisplayPort bandwidth management feature that enables DisplayPort tunnels to more efficiently co-exist with other I/O data traffic via USB4 links. This increased efficiency is on top of the forced support for VESA's visual lossless display stream compression (DSC) codecs and VESA's panel replay capabilities.

Alan Kobayashi, Chair of the VESA Board of Directors and Chair of the VESA DisplayPort Task Force, said: "Given the significant overlap of use-case models between DisplayPort and the USB4 ecosystem, achieving greater consistency between DisplayPort and USB on a universal PHY has been a particularly important piece of work in VESA." "DisplayPort 2.1 integrates DisplayPort with the USB4 PHY specification to ensure the highest video performance across a wide range of consumer products. Display transmission via DisplayPort, with its higher bit rate and proven DSC compressed visual quality, provides ample bandwidth even for HDR content for almost all practical application needs. Features such as driving multiple displays through a single cable or enabling multiple functions (such as video, power, and data transfer) on a single port no longer require any compromise in video format choice. The advanced capabilities of DisplayPort's video interface benefit from our valuable contributions from more than 300 member companies across the electronic ecosystem."
