Use this adapter to connect two independent displays to a single mDP 1.2 port&lt;br/&gt;&lt;br/&gt;This MST hub lets you connect two DisplayPort monitors to your Mini DisplayPort computer. MST works on any Windows device that supports DisplayPort 1.2 such as models of the Lenovo Think Pad and Microsoft Surface. When connected to earlier revisions of DisplayPort such as DP 1.1 the MST hub acts as a video splitter.The MST hub is USB powered so the only thing you&#39;ll need to operate the hub is your computer.&lt;br/&gt;&lt;br/&gt;Increase your productivity with multiple monitors&lt;br/&gt;&lt;br/&gt;The newest generations of laptops are more portable than ever unfortunately this means youre left with fewer video outputs and a small integrated screen. The MST hub solves these problems by letting you connect two independent displays to a single mDP port on your computer which makes multitasking much easier. Using the MST hub you can extend your desktop onto additional monitors and stream independent content to each display which makes it easier to multitask and increase your productivity - perfect for creating an easy-to-dock hot desk solution with a wireless keyboard and mouse peripheral set. You can also mirror the same image onto multiple displays for remote viewing applications such as digital signage.&lt;br/&gt;&lt;br/&gt;Astonishing picture quality that wont drain your system resources&lt;br/&gt;&lt;br/&gt;MST technology uses your existing video card to minimize the use of system resources while delivering Ultra HD 4K resolutions. 4K is supported by the latest A/V devices and delivers four times the resolution of 1080p.
