    I read from a different vendor that Mac OS X does not support Extended Desktop using MST technology, it will only mirror the displays. Can someone confirm that I can use extended desktop from Mac OS X to two monitors with this device?

    BEST ANSWER: You are correct, Mac OS X does not support MST Technology.
    Will this split a signal from a Microsoft Surface Pro docking station mini displayport into a 1080P TV monitor and a flat-screen computer monitor shown simultaneously while the other docking station output goes from mini displayport to VGA? Essentially having 3 monitors running at the same time.

    MacBook Air detects the two external monitors as one display, both showing the same extended desktop. How can I get the system preferences to detect both external displays independently?
    Mickey P on Nov 27, 2017
    BEST ANSWER: Apple does not support Multi-Stream Transport, which means that this adapter will not give you the capability to run two extended displays on an Apple computer.
    What is the power source for the MSB hub?
    Is it USB powered or JUST the mDP port does the job?
    A shopper on Aug 11, 2018
    BEST ANSWER: I’ve only used MSB on a usb powered port on a Mac Mini, it appears the power is being supplied through the USB port of the Mac Mini.
    Are the female connections HDMI?

    Working very well!
    Using it with a Surface Pro 4 to be able to have 2 external monitors and everything works like a charm.
