Product information

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.
