The MSTMDP123DP Mini DisplayPort 1.2 to DisplayPort MST Hub lets you create a high quality multi-monitor setup without having to install a multi-head video card, by connecting up to three DisplayPort monitors/projectors to a single Mini DisplayPort (1.2) output on your ultrabook, laptop, or Desktop computer. The hub splits the single output into three separate signals, enabling you to extend your desktop to increase workspace, or mirror your primary display to a different monitor or projector. With separate image outputs and resolution support up to 2560x1600 per monitor/projector, the DisplayPort MST hub allows monitors connected through the hub to operate individually as if they were connected directly to your Mini DisplayPort 1.2 video card. The MST hub is compatible with Intel Thunderbolt, when connected directly to a supporting DisplayPort over Thunderbolt I/O port.
