StarTech.com 3-Port USB-C Multi-Monitor Adapter: Type-C to 3x HDMI MST Hub

Unlock expansive productivity with the StarTech.com 3-Port USB-C Multi-Monitor Adapter. Designed for professionals who demand more screen real estate from their laptops, this compact MST hub lets you connect three HDMI displays to a single USB-C Windows device. By leveraging DisplayPort Alt Mode, you can extend your desktop, mirror presentations, and create an immersive multi-monitor setup that transforms how you work, analyze data, and collaborate with teammates. Whether you’re juggling complex spreadsheets, running design software, coding across multiple windows, or monitoring real-time data streams, this adapter delivers reliable performance, crisp visuals, and streamlined workflow integration.

• Expand your workspace with three independent HDMI displays from a single USB-C connection. This enables you to keep reference materials on one screen, primary work on another, and communications or monitoring tools on a third. The result is a truly multi-dimensional desktop that enhances focus and reduces the time spent switching between applications.
• Triple 1080p HDMI outputs deliver crisp text and smooth video for detailed work. Each display can render 1080p content at a comfortable 60 Hz, making it suitable for spreadsheets, code editors, video calls, and design previews without noticeable latency or motion blur. This clarity helps reduce eye strain during long sessions and improves overall readability of on-screen data.
• Multi-Stream Transport (MST) hub technology manages multiple video streams from one USB-C source. By distributing separate video signals to each HDMI port, you can create a flexible array of displays that function as an extended workspace or, where needed, mirror specific content to other rooms or meeting spaces. The MST approach is designed to maximize compatibility with compatible Windows devices that support multi-monitor setups.
• Plug-and-play simplicity on Windows systems with straightforward setup. In most cases, you simply connect the hub to a USB-C port on your Windows laptop or desktop, attach your three HDMI displays, and configure the display layout in Windows Settings. This minimizes downtime and lets you begin a multi-monitor workflow quickly, whether you’re in a home office, corporate workspace, or a mobile workstation environment.
• Compact, portable, and robust design for everyday use. The adapter’s form factor fits neatly on a desk or into a bag for travel, making it ideal for remote workers, students, engineers, designers, and professionals who rotate between sites. The solid build withstands regular daily use and supports reliable performance across a range of working environments.

• A: In most standard Windows configurations, the hub can operate using power supplied by the USB-C host. External power is typically not required for basic three-display setups. However, certain high-demand configurations or laptops with limited USB-C power delivery may benefit from additional power to ensure stable performance, so review your device’s power delivery capabilities if you encounter any display issues.
• Q: Can I mirror content across all three displays or only extend?
• A: You can choose to either extend your desktop across the three displays or mirror content on all displays, depending on your Windows display settings and how you configure the MST hub. This flexibility supports presentations, collaborative work, and scenarios where sharing the same content on multiple screens is advantageous.
• Q: What are the key requirements to get started?
• A: A Windows PC with an available USB-C port that supports DisplayPort Alt Mode and multi-monitor configurations is needed. You’ll also need three HDMI displays and HDMI cables. Ensure your system’s graphics drivers are up to date, and be prepared to adjust Windows display settings to achieve the desired layout and resolution across all three screens.
