## Long description

The StarTech.com MSTDP123DP Multi Monitor Adapter lets you connect up to three independent displays to a single DisplayPort 1.2 port on a Windows laptop or desktop. The compact adapter supports DisplayPort MST (Multi-Stream Transport) to extend or mirror your desktop across multiple monitors and is compatible with HDMI, DVI and VGA displays when used with appropriate passive or active adapters. The adapter is VESA and DisplayPort certified and is available in a compact black enclosure with a short integrated cable (0.19 m).
Advantages
This adapter enables multi-monitor configurations from a single DP 1.2 output, reducing the need for multiple video ports. It supports high-resolution outputs including Ultra HD 4K (at 30Hz) while minimizing system resource usage via MST technology. The MSTDP123DP is plug-and-play on Windows systems, compatible with a wide range of displays through standard video adapters, and is backed by a StarTech.com 3-year warranty and free lifetime technical support.
Suitable for
Extending a Windows desktop across up to three monitors for increased productivity
Mirroring a single image across multiple displays for signage or presentations
Connecting mixed display types (DisplayPort to HDMI/DVI/VGA) using compatible adapters
High-resolution workflows such as graphic design, medical imaging or content review (subject to bandwidth limits)

How to use
Connect the adapter’s DisplayPort plug to your computer’s DP 1.2 port, then attach your monitors using DisplayPort cables or DisplayPort-to-HDMI/DVI/VGA adapters as required. On Windows systems the adapter supports plug-and-play; configure display modes (extend or duplicate) in Display Settings. If your system has DisplayPort 1.1 instead of 1.2, the adapter will mirror the source across all displays rather than providing independent outputs. Monitor resolutions must be chosen so the total MST bandwidth (21.6 Gbps) is not exceeded.
Usage recommendations
Allocate bandwidth according to the listed average resolution percentages (for example, 1920x1080@60Hz ≈22%, 2560x1440@60Hz ≈35%, 3840x2160@30Hz ≈38%) and avoid configurations that total more than 100% to prevent reduced functionality. Some graphics adapters support only a total of three displays; connecting more than three monitors may disable the fourth.
