StarTech.com 3-Port Mini DisplayPort to HDMI MST Hub — 3x1080p Extended Desktop for Windows

Unlock a more productive workflow with the StarTech.com 3-Port Multi Monitor Adapter. This compact, robust MST hub turns a single Mini DisplayPort (DP) output into three independent HDMI displays, enabling a seamless extended desktop that keeps tools, dashboards, and applications organized side by side. Built for professionals who demand clarity, reliability, and simplicity, this device makes multi-monitor setups fast to deploy without the clutter of extra video cards or complex cabling. Whether you’re coding, designing, analyzing data, or monitoring complex workflows, the three HDMI outputs deliver crisp 1080p visuals with smooth performance, so you can work more efficiently and make faster, better decisions.

• Triple-monitor expansion from one Mini DisplayPort source: From a single DP output, drive three independent HDMI displays. Create a wide, immersive workspace for design mockups, live dashboards, financial monitoring, or software development. Each monitor can be arranged, scaled, and color-calibrated independently, so you have exactly the view you need for every task.
• Powerful MST technology for true extended desktop: Leveraging Multi-Stream Transport (MST), this hub streams three distinct video feeds to separate screens. The result is a robust extended desktop that minimizes window chaos and maximizes productivity—perfect for environments where multiple applications must be visible at once, such as data analysis, trading, software testing, and collaboration sessions.
• 1080p clarity with reliable audio passthrough: Each HDMI output supports full HD 1080p at 60 Hz, delivering sharp text, smooth video, and consistent UI rendering across all displays. Audio is carried via HDMI, so you can hear system sounds, video audio, and conferencing feeds directly from your monitors or external audio devices connected to the displays.
• Plug-and-play design with broad Windows compatibility: This MST hub is designed for fast setup on Windows workstations. No heavy driver installations are typically required, so you can start expanding your screen quickly. It’s compatible with Windows environments (Windows 7/8/10/11 and later), making it a versatile upgrade for a wide range of PCs and laptops.
• Compact, rugged build for desk-friendly deployment: The slim, metal-enclosed chassis keeps your workspace tidy and travel-ready. Its durable construction withstands daily use in busy offices and on business trips, while the fanless design runs quietly in meetings, labs, and classroom settings.

how to install StarTech.com 3-Port Multi Monitor Adapter

• Power down your computer and ensure you have a valid Mini DisplayPort 1.2 output. Prepare three HDMI cables and three compatible displays configured to accept input from HDMI sources.
• Connect a Mini DisplayPort cable from your DP-enabled computer to the MST hub input. Confirm the connection is secure on both ends before proceeding.
• Attach three HDMI cables from the MST hub outputs to your three monitors. Use HDMI 1.4b-compatible cables to ensure stable performance at 1080p and synchronized audio.
• Power on the displays and boot your computer. Open Windows Display Settings to configure the layout. Choose Extend desktop for all three displays and align them to match your physical arrangement on the desk.
• Set each monitor’s resolution to 1080p (or the maximum supported by your hardware) and adjust orientation (landscape or portrait) as needed. If you encounter an issue where one monitor isn’t displaying, verify that the DP cable is seated correctly and that your graphics driver supports MST on your GPU.
• If you use audio, confirm that HDMI audio is selected in the sound settings or route audio through the monitors. For best results, update your graphics drivers to the latest version to ensure full MST and multi-monitor support.

Frequently asked questions

• Will I get 4K on each display with this hub? The hub is designed for up to 1080p per display. While some DP sources and HDMI outputs can support higher resolutions, the practical specification for this adapter is three independent 1080p displays at 60 Hz, making it ideal for extended desktop productivity rather than 4K gaming or editing across all displays simultaneously.
• Is this compatible with non-Windows systems? This device is designed with Windows in mind and is widely used in Windows environments. Compatibility with macOS or Linux is not officially guaranteed and may depend on vendor drivers and system configurations. If you require macOS compatibility, look for StarTech options specifically listed for macOS support.
• Do I need any external power for reliable operation? In typical setups, the hub draws power from the DisplayPort connection and does not require an external power supply. If you run into instability with certain GPUs or long cable runs, consult your hardware documentation to determine if additional power or a powered USB-C/DP hub is recommended for your configuration.
• Can the displays be mirrored or must they be extended? The primary purpose of the MST hub is to extend your desktop across three displays. Windows allows you to mirror displays if needed, but the most efficient layout for multitasking is usually a dedicated extended desktop with windows spread across monitors.
• Do drivers need to be installed? In many Windows installations, the MST hub works with no extra driver installation. To optimize performance, ensure your graphics card drivers are up to date and that MST is enabled in your GPU settings. Windows Update can also help ensure optimal multi-monitor support.
• What kind of USB or docking compatibility does it have? This device uses a DisplayPort interface to drive HDMI outputs and does not rely on a USB power or data connection for the monitors themselves. If you’re incorporating it into a docking setup, ensure your dock and GPU support MST to avoid conflicts.
