Maximum number of displays


I am not sure, how to interpret the Datasheet of Quadro P620 and P1000.
It says: “Max Simultaneous Displays: 4 direct, 4 DP 1.4 Multi-Stream”

Does this mean 4 displays in total or 4 times Multi-Stream?
With one DP 1.4 Multi-Stream, I can connect up to 4 FullHD Displays, so 4x Multi-Stream would be 16 FullHD Displays.

Can someone shed some light on that?
