Multiple displays on single DisplayPort connector[edit]
DisplayPort 1.2 added support for Multi-Stream Transport (MST), enabling multiple monitors to be used via a single DisplayPort connector. This function requires either monitors that are capable of DisplayPort 1.2 daisy-chaining, or use of a DisplayPort MST Hub. The first MST hub became available in September 2013, enabling up to 3 displays to be connected to a single DisplayPort connector.[29]
Single Stream Transport (SST) was specified in DisplayPort 1.1a for use between a single Source and Sink Device.
