Important operation notes
• Some computer systems may prevent this MST hub from
displaying digitally encrypted content.
• A computer, laptop or tablet with DisplayPort 1.2 is required for
MST support.
• If your device only supports DisplayPort 1.1, the MST hub will
act as a splitter, automatically mirroring your video source across
all displays.
• MST is certied for operation with Microsoft Windows 8 devices.
Other operating systems may adopt the technology. Please check
with your operating system vendor to conrm support. Operating
system support is subject to change. For the latest requirements,
please visit:
www.StarTech.com/MSTMDP123HD.
• After the MST hub is attached, it may be necessary to initiate
operation of additional displays from within your Display settings.
• The SCAN button resyncs all of the attached displays, and can be
utilized if any of the displays are not detected.
• Certain graphics adapters such as the Intel based chips found on
the Microsoft Surface™ Pro 3, have limited MST support and will
only output to three displays in total. If you attach more than three
displays, all of the displays beyond that number will be disabled,
including the touch screen on the Surface Pro 3.
• MST shares 21.6 Gbps of bandwidth across all attached displays.
Higher resolutions can restrict the bandwidth available for the
remaining ports. Please see our guidelines below for determining
the ideal resolution for your setup.
