StarTech.com 3-Port Multi Monitor Adapter, DisplayPort 1.2 to HDMI MST Hub, Triple 1080p HDMI Monitor, Video Splitter for Extended Desktop Mode on Windows PCs Only, DP to 3x HDMI MST Hub - Multi Stream Transport (MSTDP123HD) - Video/audio splitter - 3 x H

This MST hub lets you connect three HDMI monitors to your DisplayPort (DP) 1.2 equipped Windows 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 three additional displays to 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. You can also mirror the same image onto multiple HDMI televisions or projectors 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 MSTDP123HD will act as splitter, automatically mirroring your video source across all displays. Resolution limitations apply.
Note: 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. Some monitors limit available resolution.
