Both ends of the DisplayPort 2.1 cable will be marked with DP40 or DP80, which is convenient for users to distinguish. The certified DP40 data cable can support up to Ultra-High Bit Rate (UHBR)10 10Gbps, and the combination of four channels is 40Gbps; The DP80 certified data cable supports Ultra-High Bit Rate (UHBR)20 20Gbps, and the maximum of four channels combined is 80Gbps.

In version 2.1, VESA introduced DP40 and DP80 cable certification layers to verify UHBR 10 and UHBR 20 speed cables respectively.
