StarTech.com 4 Port Mini DisplayPort MST Hub - 4K 30Hz - Mini DP to DisplayPort Splitter for Multiple Monitors - mDP to DP (MSTMDP124DP) - Video splitter - 4 x DisplayPort - desktop

This MST hub lets you connect four monitors to your Mini DisplayPort (mDP) 1.2 equipped Windows tablet, laptop or desktop.
The newest generations of computers are more portable than ever, which often means that you're left with fewer video outputs and smaller integrated screens. This MST hub solves both of these problems by letting you connect four additional displays to your computer, which makes multitasking much easier.
With the MST hub, you can use Mini DisplayPort video adapters and cable adapters that enable you to connect HDMI, VGA or DVI displays. This ensures that your MST hub will be compatible with virtually any television, monitor or projector. The hub is VESA and DisplayPort certified to support DP 1.2 enabled systems, for seamless integration with your existing video equipment.
Using the MST hub, you can extend your desktop onto additional monitors and stream independent content to each display, giving you the freedom to multitask and increase your productivity. You can also mirror the same image onto multiple displays for remote viewing applications such as digital signage.
MST technology uses your existing video card to minimize the use of system resources while delivering Ultra HD 4K resolutions. This unprecedented performance makes MST perfect for high-resolution applications such as graphic design, gaming and medical imaging.
Note: When using a DisplayPort 1.1 video card the MSTMDP124DP will act as a splitter, automatically mirroring your video source across all displays. Resolution limitations apply.
Notes: MST shares 21.6 Gbps across all attached displays. Higher resolutions can restrict the available bandwidth with the remaining ports. Certain graphics adapters have limited MST support and will only output to three displays in total. If more than three monitors are attached, the fourth will be disabled.
The Surface Pro 3, Surface Pro 4, and Surface Book only support the use of three displays in total. If this device is used with the Surface Pro 3, and three external monitors, the built-in touch screen on your Surface will be disabled.
