DisplayPort 2.0, which was launched in June 2019, supplies as much as a 3X enhance in knowledge bandwidth efficiency in comparison with the earlier model of DisplayPort, in addition to new capabilities to deal with future efficiency necessities of shows. These embody beyond-8K resolutions, larger refresh charges and excessive dynamic vary (HDR) help at larger resolutions, improved help for a number of show configurations, in addition to improved person expertise with augmented/digital (AR/VR) shows, together with help for 4K-and-beyond VR resolutions. Featuring the extremely environment friendly 128b/132b channel coding shared with USB4, DisplayPort 2.Zero delivers a most payload of 77.37 Gbps throughout 4 lanes (as much as 19.34 Gbps per lane)—supporting ultra-high show efficiency configurations equivalent to an 8K (7680×4320) show with 60 Hz refresh fee with full-color 30 bpp 4:4:Four HDR decision uncompressed, and 16Ok (15360×8460) 60 Hz show with 30 bpp 4:4:Four HDR decision with compression. With the discharge of DisplayPort Alt Mode 2.0, all of those high-performance video capabilities at the moment are obtainable to the USB ecosystem.
“VESA’s updated DisplayPort Alt Mode spec includes a number of under-the-hood developments—including updates to interface discovery and configuration as well as power management—to ensure seamless integration with the USB4 specification,” acknowledged Craig Wiley, senior director of promoting at Parade Technologies, and VESA board member and DisplayPort Alt Mode sub-group chief. “This major undertaking, which was several years in the making, could only be made possible through the combined efforts of VESA and the USB-IF. Through our latest collaboration with the USB-IF, VESA is now taking care of everything related to high-performance displays over USB-C, whether through a native DisplayPort or USB-C connector, or through tunneling of DisplayPort over the native USB4 interface. DisplayPort is also tunneled through the Thunderbolt interface, making it the de facto video standard across PC and mobile displays.”
“USB Type-C is becoming the connector of choice in notebooks and mobile solutions. With the new DisplayPort Alt Mode 2.0 specification, USB Type-C now delivers compelling single-connector solutions for docking, gaming, AR/VR HMDs, and professional HDR displays that combine 80 Gbps of video bandwidth and other important features of DisplayPort 2.0 with the transport of USB data and power delivery,” stated Syed Athar Hussain, VESA board vice chairman and show area senior fellow, AMD.
“Intel’s contribution of the Thunderbolt PHY layer specification to VESA for use in DisplayPort 2.0 was a significant milestone, and it underpins this new DisplayPort 2.0 Alt Mode specification to provide data rates up to 20 gigatransfers per second,” stated Jason Ziller, basic supervisor, Client Connectivity Division at Intel. “This contribution ensures great user experiences by enabling today’s most versatile port with the highest performing display capabilities.”
