VESA announced DisplayPort version 2.1 in October 2022. This update introduces DP40 and DP80 cable certifications to ensure proper operation at speeds of 40 Gbit/s and 80 Gbit/s, respectively, as introduced in version 2.0. It also revises electrical requirements to better integrate with USB4.

DisplayPort 2.1 aligns more closely with USB Type-C and USB4 PHY specifications, enabling a common PHY for both DisplayPort and USB4. Additionally, it adds a new bandwidth management feature to facilitate more efficient coexistence with other I/O data traffic over USB4.
