Review on StarTech.com Dual DisplayPort 1.2 MST Hub - 2-Port Multi Monitor Adapter for Extended Desktop Mode - Supports Dual 4K 30Hz or 1080p - USB Bus Powered - Windows PC Compatible - DP to 2x DP (MSTDP122DP) by William Stewart

This is a replacement for the much more expensive Matrox triple display. It works a little oddly, but after some tweaking it works fine... Decent value at half the price of Matrox. Which just stopped working after a few years, so can't complain. In addition to my review, I've found this device to go haywire at times, especially if your system is set to turn off monitors after a period of time... I'm not confused and a full reboot is usually required to recover the screens correct, other than that works very well… I just turned off the sleep mode and took a screenshot and turned the screens off manually And it seems to work Doesn't work properly After a few weeks of using this device I've found that it tends to die Cluttering screens and losing the idea of what's being displayed, where also it takes a long time to start up, and if I don't leave the monitors on instead of using auto-off often requires a full system reboot, Matrox never did that , so I bring it back and s looking for another solution here
