## Long description

The StarTech.com Multi Monitor Adapter MSTMDP123DP connects up to three independent displays to a single Mini DisplayPort (mDP) 1.2 port. It supports DisplayPort MST on compatible Windows systems to extend or mirror your desktop across multiple monitors. When used with earlier DisplayPort revisions, the adapter functions as a video splitter.
Advantages
This adapter enables multi-monitor setups from a single mDP output, supporting high-resolution output including 4K where supported by the connected devices. It minimizes additional system resource usage by leveraging the host video card and is compatible with a wide range of displays using optional mDP-to-HDMI, mDP-to-DVI or mDP-to-VGA adapters. The compact, lightweight design and VESA/DisplayPort certification simplify integration with laptops and docking setups.
Suitable for
Extending desktop workspace for multitasking on Windows laptops that support DisplayPort 1.2
Presentations or digital signage using mirrored displays
High-resolution work such as graphic design or medical imaging

How to use
Connect the adapter to the computer’s Mini DisplayPort 1.2 output. Attach up to three DisplayPort monitors to the adapter or use separate mDP-to-HDMI/DVI/VGA adapters to connect other display types. On Windows devices that support DisplayPort 1.2 MST, configure displays in the operating system display settings to extend or mirror the desktop as required. If the host uses an earlier DisplayPort revision, the adapter will operate as a splitter and mirror the same image to connected displays.
Usage recommendations
For best results use with Windows systems that explicitly support DisplayPort 1.2 MST. Use high-quality display cables and, when needed, active adapters for long cable runs or for converting to HDMI/DVI at high resolutions. Check the combined bandwidth and individual display resolutions to ensure the desired arrangement (for example, two 4K displays at 30 Hz plus one 1080p). Ensure the host GPU and drivers are up to date for optimal multi-monitor performance.
