Daisy-chaining is a feature that must be specifically supported by each intermediary display; not all DisplayPort1.2 devices support it. Daisy-chaining requires a dedicated DisplayPort "output" port on the display. Standard DisplayPort "input" ports found on most displays cannot be used as a daisy-chain output. Only the last display in the daisy-chain does not need to support the feature specifically or have a DP output port. DisplayPort1.1 displays can also be connected to MST hubs, and can be part of a DisplayPort daisy-chain if it is the last display in the chain.
