StarTech.com 3-Port Multi Monitor Adapter: Mini DisplayPort 1.2 to DP MST Hub for Windows

Transform your workstation with the StarTech.com 3-Port Multi Monitor Adapter, a compact and powerful solution that turns a single Mini DisplayPort 1.2 output into three DisplayPort displays. Designed for Windows devices, this DP MST hub delivers an expanded desktop experience, enabling true multitasking across three monitors without clutter or complexity. Whether you’re refining spreadsheets, editing video, or designing in multiple windows, this adapter helps you unlock a wider field of view, smoother workflows, and enhanced productivity.

• Unleash triple-monitor productivity by converting one Mini DisplayPort 1.2 output into three DisplayPort displays. This MST hub supports extended desktop across three screens, giving you more screen real estate for complex tasks, data dashboards, or creative workflows. With three independent DP outputs, you can arrange your monitors in landscape or portrait orientations to suit your workflow, minimizing alt-tabbing and maximizing focus.
• Sleek, space-saving design that drapes cleanly into any desk setup. The compact form factor and bus-powered approach reduce cable clutter and eliminate the need for bulky external power adapters in most configurations. It plugs into your laptop or desktop and delivers a tidy, scalable multi-monitor solution that complements portable workstations and fixed workstations alike.
• Advanced Multi-Stream Transport (MST) technology enables true extended desktop across multiple displays. By leveraging DP 1.2’s MST capabilities, this hub splits a single DP stream into three independent outputs, allowing you to mirror or extend content across monitors as dictated by your Windows display settings. This creates a cohesive, wide-screen environment ideal for trading, design reviews, software development, and immersive data analysis.
• Windows-focused compatibility for reliable performance. Built for Windows environments, this adapter works with supported Windows operating systems and commonly available graphics drivers. It’s designed for straightforward setup with plug-and-play convenience, so you can quickly assign each monitor’s position, resolution, and orientation from Windows Display Settings.
• Easy install, flexible configuration, and robust reliability. The 3-Port DP MST Hub is engineered for durability and long-term use in busy workspaces. It supports standard DisplayPort cables, works with most DisplayPort monitors, and provides flexible configuration options so you can tailor the layout to your specific needs, whether you’re developing software, monitoring analytics, or delivering client presentations.
