Elevate your workstation with a single DisplayPort 1.4 connection that multiplies your display real estate. The StarTech.com Dual-Monitor DisplayPort 1.4 Splitter is a compact, high-performance MST hub designed to drive two displays from one DP source. Built for Windows environments, this adapter-based solution delivers crisp 4K at 60Hz and HDR experiences across dual monitors, while also supporting advanced multi-stream transport (MST) technology to consolidate multiple video signals into one streamlined output. If you need to boost productivity, create immersive content workflows, or deliver precise data at a glance, this MST hub is the dependable bridge between a single DP 1.4 port and two pristine DisplayPort displays.

• Expand with ease — turn a single DisplayPort 1.4 source into two independent DisplayPort outputs, letting you run two monitors side-by-side for immersive productivity, enhanced gaming setups, or professional workflows without swapping cables or upgrading your GPU.
• High-fidelity visuals — supports up to 4K resolution at 60Hz per display with HDR, delivering vibrant color, deep contrast, and smooth motion. The MST hub is designed to preserve image quality while splitting the signal to two displays, making it ideal for video editing, CAD, financial dashboards, and creative work that benefits from precise, accurate visuals.
• Future-friendly MST technology — Multi-Stream Transport (MST) enables multiple video streams to be transported over a single DisplayPort link. This lets you manage two displays from one DP input with flexible display arrangements, optimized color and timing, and simplified cable management.
• Windows-ready plug-and-play — engineered for Windows environments, this MST hub offers a plug-and-play experience with minimal setup. No additional drivers are typically required, and Windows display settings can be used to arrange, extend, or mirror your desktop across both monitors according to your needs.
• Compact, durable design for professionals — a compact, rack-friendly form factor that sits neatly on your desk or mounts behind a monitor. Built to handle daily use by professionals—developers, designers, data analysts, and engineers—without adding bulk to your workspace. The dual-output design also helps reduce cable clutter and simplify workspace ergonomics.

How to install StarTech.com Dual-Monitor DisplayPort 1.4 Splitter

• Power down your computer and monitors before beginning the installation.
• Connect the DisplayPort 1.4 output from your video source (GPU/PC) to the MST hub input.
• Attach a DisplayPort cable from the first hub output to the first monitor, and a second DisplayPort cable from the second hub output to the second monitor.
• Power on the monitors and boot your computer. In Windows, open Display Settings to arrange the two displays (extend, duplicate, or custom alignment) and set preferred resolutions for each monitor.
• If necessary, enable MST mode or adjust multi-display options in your graphics driver control panel. Ensure both displays are detected and configured for the desired refresh rate (up to 60Hz for 4K, higher rates may be available depending on your GPU and monitor capabilities).
• Fine-tune color, brightness, and contrast on each screen to achieve consistent visuals across both displays. Save your configuration and test with your typical applications to confirm performance and reliability.

Frequently asked questions

• What is an MST hub? An MST hub uses Multi-Stream Transport to split a single DisplayPort input into multiple independent outputs, allowing two displays to be driven from one DisplayPort source without requiring a second graphics port.
• What resolutions can I expect with this StarTech MST hub? The hub supports 4K at 60Hz on each display with HDR. With compatible hardware and bandwidth, dual-display configurations can also accommodate higher-end setups such as 5K at 60Hz on each display, though actual ability depends on your GPU, monitors, and DisplayPort cables.
• Do I need external power? No external power is typically required—the device is bus-powered from the host DisplayPort connection. Ensure your GPU and host system provide adequate bandwidth for your chosen resolution and refresh rate.
• Is this solution compatible with macOS or Linux? The product is specified for Windows environments. While some DP MST hubs may work with other operating systems, official support and guaranteed performance are provided for Windows systems; check your OS and GPU driver capabilities if you are using macOS or Linux.
• Will I need drivers? In most Windows setups, no additional drivers are required. You may need to adjust display settings in Windows to arrange the two monitors and set individual resolutions and scaling as needed.
