Packaging Contents

3-Port Multi Monitor DisplayPort® MST Hub
1x Universal Power Adapter (NA/EU/UK/AUS)
1x Instruction Manual

System Requirements

DisplayPort 1.2 enabled computer system/video card
Up to 3 DisplayPort enabled display devices (e.g. monitor) with cabling

Important operation notes

Different types of displays, such as HDMI®, DVI, and VGA work with this MST hub, provided the appropriate DisplayPort adapter is used. DisplayPort adapters aren’t included. The StarTech.com SKU for each adapter is listed below:
DisplayPort to HDMI adapter (DP2HDMI)
DisplayPort to VGA adapter (DP2VGA3)
DisplayPort to DVI adapter (DP2DVI2)
A DisplayPort 1.2 video card or source is required for MST support.
When using a DisplayPort 1.1 video card, the MST hub acts as a splitter, automatically mirroring your video source across all of the displays.
MST is certified for operation with Microsoft® Windows® devices. Other operating systems may adopt the technology; please check your operating system vendor to confirm support. Operating system support is subject to change. For the latest requirements, please visit www.startech.com/MSTDP123DP.
After the MST hub is attached, it may be necessary to initiate the 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 aren’t detected.
Certain graphics adapters, such at 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 10.2 Gbps of bandwidth across all of the attached displays. Higher resolutions can restrict the bandwidth available for the remaining ports. Please see the guidelines below to determine the ideal resolution for your setup.

Average resolution bandwidth allocation

1920 x 1080 (High-definition 1080p) @60hz – 22%
1920 x 1200 @60hz – 30%
2560 x 1440 @60hz – 35%
2560 x 1600 @60hz – 38%
3840 x 2160 (Ultra HD 4K) @30hz – 38%

Note: Exceeding 100% will reduce functionality.

Installation

Ensure your computer system and DisplayPort Displays are powered off.

Connect the DisplayPort monitor/display device(s) into the DisplayPort #1/#2/#3 connectors on the MSTDP123DP MST Hub.

The system will now detect the MST Hub, and add the attached displays to the Display Settings of the System.
