## Summary description

StarTech MSTMDP123HD is a Mini DisplayPort to HDMI adapter that uses Multi-Stream Transport (MST) to provide three HDMI outputs from a single Mini DP source. It enables connection of up to three external HDMI displays for extended or mirrored desktops, supports video transmission for multi-monitor setups, and is suited for productivity, presentations, and workspace expansion.

## Long description

The StarTech MSTMDP123HD Mini DisplayPort to HDMI adapter uses Multi-Stream Transport (MST) to split a single Mini DisplayPort output into three independent HDMI outputs. This compact adapter enables connection of up to three external HDMI monitors for extended or mirrored desktop configurations, providing a practical solution for multi-monitor workstations, presentations, and improved productivity without requiring multiple discrete video outputs on the host device.
Advantages
This adapter supports three HDMI displays from one Mini DisplayPort source, allowing expanded desktop space or duplicate screens for presentations. It preserves digital video quality across connected displays and simplifies cabling by using one host connector. The unit is compact and portable, suitable for laptop and desktop use, and compatible with systems that support DisplayPort MST functionality.
Suitable for
 Office workstations requiring multiple monitors for spreadsheets, code or data analysis
 Presentation setups where mirrored displays are needed for audience and presenter
 Home offices where a single Mini DP-equipped device must drive several HDMI screens
 Trading desks or control rooms that need extended desktop layouts
Key specifications
 Input: Mini DisplayPort (single-port MST source)
 Outputs: 3 × HDMI ports supporting independent or mirrored displays
 Supports Multi-Stream Transport (MST) for multiple monitor configurations
 Video: digital HDMI signal; actual resolutions and refresh rates depend on host GPU and monitor capabilities
 Form factor: compact adapter for portable use
How to use
Connect the adapter's Mini DisplayPort plug to the host device's Mini DP output. Attach up to three HDMI cables from the adapter's HDMI ports to the corresponding HDMI inputs on your displays. Ensure the host system has DisplayPort MST enabled and that graphics drivers are up to date. Configure display mode (extended or mirrored) in the operating system's display settings to arrange screens and select resolutions. If some displays do not appear, verify cable connections and confirm the host GPU supports the combined bandwidth for the desired resolutions.
Usage recommendations
For optimal performance, use high-quality HDMI cables and verify that your computer's graphics hardware supports DisplayPort MST and the combined resolution/refresh rates you intend to run across three monitors. Update the system graphics drivers and check monitor settings if displays require adjustment.
