## Long description

Use this MST hub to connect three independent displays to a single DisplayPort 1.2 (DP 1.2) port on a Windows laptop or desktop. The hub is VESA and DisplayPort certified for DP 1.2 systems and supports connection to HDMI, DVI or VGA displays via appropriate adapters or cables, enabling compatibility with most monitors, TVs and projectors.
Advantages
The MST hub expands a single DP 1.2 output into three video outputs, enabling extended desktops or independent content on each screen for improved multitasking. It supports mirroring for digital signage or remote viewing and leverages MST technology to deliver high-resolution video with minimal additional system resource use. The hub is plug-and-play and includes a 3-year warranty with lifetime technical support.
Key specifications
Input: DisplayPort 1.2
Output: Three independent video outputs via DisplayPort MST (use DP-to-HDMI/DVI/VGA adapters or cables as needed)
MST bandwidth shared: 21.6 Gbps total across all displays
Supported modes: Extended desktop or mirrored displays (acts as splitter on DP 1.1 cards)
Resolution support examples: 1920x1080@60Hz, 1920x1200@60Hz, 2560x1440@60Hz, 2560x1600@60Hz, 3840x2160@30Hz (subject to total bandwidth limits)
Plug-and-play installation; no drivers required for most Windows systems
Certification: VESA and DisplayPort certified for DP 1.2
Warranty: 3-year manufacturer warranty and free lifetime technical support
How to use
Connect the MST hub to your computer's DisplayPort 1.2 output, then attach up to three displays using DisplayPort cables or DP-to-HDMI/DVI/VGA adapters as required. Configure the displays in Windows Display Settings to choose extended or mirrored modes; note that on DisplayPort 1.1 graphics cards the hub will mirror the same image to all connected displays. Consider the total available MST bandwidth (21.6 Gbps) when selecting resolutions and refresh rates for each monitor to avoid exceeding capacity.
Recommendations
To achieve optimal performance, plan display resolutions so total bandwidth use remains at or below 100%. For example, three 1920x1200@60Hz displays use ~90% of bandwidth, while combinations of higher-resolution screens may exceed limits and disable functionality on one or more outputs. If your graphics adapter has limited MST support, the total number of active displays may be restricted to three.
