MST Hub - Mini DisplayPort to 3x HDMI

*actual product may vary from photos

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 certified for operation with Microsoft Windows 8 devices.  

  Other operating systems may adopt the technology. Please check  

  with your operating system vendor to confirm 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
