The Video Electronics Standards Association (VESA) today announced the release of Display Port 2.1. Brings some improvements over DisplayPort 2.0, such as tighter specification compliance USB Type-C and USB4 PHY, improved connectivity through DisplayPort over USB4 tunneling and longer cable lengths while maintaining high performance.
Hot on the heels of DisplayPlay 2.0 released earlier this year, DisplayPort 2.1 facilitates a larger PHY towards the USB Type-C and USB4 PHY specifications. The new version has also added a DisplayPort bandwidth management feature that allows the DisplayPort tunnel to work alongside other I/O traffic over USB4 with great efficiency.
Alan Kobayashi, Chairman of the VESA Board of Directors and Chairman of the vesa DisplayPort Working Group, says, “Achieving greater alignment between DisplayPort and USB on a common PHY has been a particularly important effort within VESA given the significant overlap in models. of use cases between the DisplayPort and USB4 ecosystems”.
Speaking about DisplayPort 2.1 and its convergence with the USB4 PHY specifications, Kobayashi also states that “features like driving multiple displays over a single cable, or enabling multiple functions on a single port like video, power, and data transfer, no longer require no compromise on the choice of video format.”
Another improvement that comes with the DisplayPort 2.1 specification is with full-size and Mini DisplayPort cable configurations. Ultra-high bit rate (UHBR) performance over VESA-certified DP40 (max. 40 Gbps with four lanes) and DP80 (max. 80 Gbps with four lanes) cables are now claimed not to decrease with longer cable lengths ( more than one meter for DP80 and more than two meters for DP40).
