DisplayPort UFP_D pin assignment D is similar to UFP_D assignment C, except only the two lowest DisplayPort lanes are mapped to the USB-C connector. DisplayPort electrical mandates for pin assignment D need to comply with the DisplayPort standard for bit rates up to UHBR 20, UHBR 13.5, UHBR 10, HBR 3, HBR 2, HBR or RBR, as supported by the system. The protocol is defined in the DisplayPort standard. Pin assignment D is appropriate only for USB-C-to-USB-C passive and active cables and DisplayPort sink devices with USB-C plugs. USB4 does not support UFP_D assignment D.
