Many months have gone into preparing the new standard, with VESA working with several partnering companies to adopt the new specification in their designs. This will change all active products using the previous DP2.0 specification and certify all items under the latest DisplayPort 2.1 specification. This includes components such as graphics cards, chips for docking stations, monitor scalar chips, PHY repeater chips (re-timers), and DP40 and DP80 cables of all types will now be certified under DisplayPort 2.1. VESA worked diligently to ensure that DisplayPort 2.1 would offer better throughput with its various options for consumers, from the standard DP cable, through the USB4 link (introduced this last year to assist with a combination of faster data transfers along with enhanced visual speeds), and the DP USB-C connector. Now, DP 2.1 bandwidth has a management feature that allows quicker and more efficient I/O transfers through the USB4 link connection. The output produces 67% fewer visual artifacts and a 99% bandwidth increase through DP tunneling packet transports during Panel Relay operations. Increases in cable lengths have now been extended above DP40 and DP80 cables. The DP40 line receives the same connectivity as before, but with above two-meter connections, whereas DP80 is allowed the same but above one-meter connections. Additionally, UHBR performance has been improved by offering UHBR10 link rates, 10 Gbps with four lanes, and 40 Gbps maximum throughput. UHBR20 receives 20 Gbps across four lanes for 80 Gbps maximum throughput. — Alan Kobayashi, VESA Board Chair and VESA DisplayPort Task Group Chair — James Choate, compliance program manager, VESA
