The MSTMDP123DP Mini DisplayPort 1.2 to DisplayPort MST hub lets you connecting up to three DisplayPort monitors/projectors to a single Mini DisplayPort (1.2) output on your Ultrabook, Laptop, or Desktop computer.

Extend Your Display
The hub splits a Mini DisplayPort 1.2 output into three separate DisplayPort signals -- enabling your computer for high quality multi-monitor applications such as a video wall, extending your desktop, or mirroring your primary display to additional monitors or projectors.
Extend Your Performance
With separate image outputs and resolution support up to 2560x1600 for two displays, and 1920x1200 for a third display, the DisplayPort MST hub allows monitors connected through the hub to operate individually with the exact same performance as the Mini DisplayPort 1.2 graphics card on your computer.

Extend Your Compatibility
The MST hub is compatible with Intel Thunderbolt, when connected directly to a supporting DisplayPort over Thunderbolt I/O port. You can also use DisplayPort video adapters with the MST hub, enabling you to output the additional video signals to HDMI, DVI, or VGA displays.
