DisplayPort

DisplayPort is a serial link which uses 1x, 2x or 4x lanes.

DP VersionMax Speed per lane
1.1HBR = 2.16 Gbit/s
1.2HBR = 2.16 Gbit/s\ HBR2 = 4.32 Gbit/s
1.3 / 1.4HBR = 2.16 Gbit/s\ HBR2 = 4.32 Gbit/s\ HBR3 = 8.1 Gbit/s

Dual Mode Displayport (DP++) allow to convert Displayport video signal to HDMI/DVI by using a passive adapter. It requires an active converter on host side. DP++ only supports DVI D-Single Link
