This MST hub allows you to connect two DisplayPort monitors to your laptop equipped with Mini DisplayPort. MST works on any Windows® compatible DisplayPort 1.2 device, such as Lenovo’s Think Pad® and Microsoft® Surface ™. When the MST hub is connected to earlier versions of DisplayPort, such as DP 1.1, it works as a video multiplier. The MST hub has USB power, so you only need your computer to use it.
