The SIIG 1x2 USB-C to HDMI 4K60 MST Hub Splitter brings the power of Multi-Stream Transport (MST) to your USB-C port, letting you drive two independent HDMI displays from a single USB-C connection. Built for modern laptops, ultrabooks, and desktops with USB-C or Thunderbolt ports that support DisplayPort Alternate Mode, this DP 1.4 MST Video Splitter Hub delivers crystal-clear dual 4K visuals at 60 Hz on each monitor. It’s a plug-and-play solution designed for Windows PCs, requiring no extra driver installation, so you can quick-start your dual-monitor workflow, expand your workspace, or create immersive presentation setups in minutes. If you’re a creative professional, programmer, trader, or student juggling multiple windows, this MST hub is engineered to keep your productivity flowing by delivering reliable, high-quality video output across two HDMI displays from one compact USB-C source.

  • Dual 4K60Hz HDMI outputs from a single USB-C port with Multi-Stream Transport (MST) technology enable you to drive two independent HDMI displays at up to 4K resolution at 60 Hz on each screen. This is ideal for extended desktop setups, multi-monitor workflows, and photo/video editing where every pixel matters. With MST, you can split a single USB-C DisplayPort signal so each monitor can display its own content at the highest available resolution.
  • DP 1.4 MST technology, plug-and-play – no driver installation required on Windows PCs. The hub leverages USB-C’s DisplayPort Alternate Mode to deliver robust, stable performance with minimal setup. Simply connect the hub to a USB-C/DP Alt Mode host, attach two HDMI cables, and you’re ready to go. It’s designed for a streamlined, hassle-free experience that keeps your focus on work and creativity rather than software configuration.
  • Optimized for productivity and immersive media – extend your workspace across two large 4K displays for complex spreadsheets, data visualization, and software development, or mirror content for collaborative reviews and presentations. The twin 4K60 outputs provide plenty of screen real estate, making it easier to compare documents side-by-side, monitor dashboards in real time, or watch video content while keeping your other apps accessible on a separate screen.
  • Windows PC compatibility with modern USB-C hosts – designed to work with Windows-based laptops and desktops that support USB-C with DP Alt Mode. The driver-free design ensures broad compatibility across supported devices, letting you unlock the potential of your device’s USB-C port without needing to install special software or utilities. It’s a practical upgrade for thin laptops, workstations, and gaming laptops that need extra screen capacity without sacrificing desk space.
  • Compact, portable, and easy to integrate into any setup – the hub’s sleek form factor makes it a convenient addition to home offices, classrooms, conference rooms, and on-the-go workflows. Its lightweight build minimizes desk clutter while maximizing display options. When you need two large, crisp displays at once, this MST splitter stays out of the way and keeps your setup clean, organized, and ready for action.

How to Install SIIG 1x2 USB-C to HDMI 4K60 MST Hub Splitter

Setting up this MST hub is a straightforward, plug-and-play process designed to get you dual 4K displays quickly and reliably. Follow these steps to install and configure the splitter for optimal performance:

  1. Ensure your host computer’s USB-C port supports DisplayPort Alternate Mode (DP Alt Mode) and MST. This is essential for delivering dual HDMI outputs at 4K60 on each display.
  2. Power off your computer (optional but recommended for some setups) and disconnect any HDMI cables from the displays.
  3. Connect the SIIG MST hub to the USB-C/DP Alt Mode port on your computer using the USB-C connector on the hub.
  4. Attach an HDMI cable from the first HDMI output on the hub to Display 1 and a second HDMI cable from the second HDMI output to Display 2.
  5. Power on the displays and boot your computer. In Windows, open Display Settings to configure the dual-monitor layout. Choose Extend Desktop to spread windows across both screens or Duplicate to mirror content, and set each monitor to its native resolution (up to 4K60Hz where supported).
  6. Apply the settings and adjust scaling as needed. If you encounter issues, verify that the host USB-C port supports MST and DP Alt Mode, and confirm that both HDMI cables and displays are HDMI 2.0-compatible and configured for 4K60 Hz where available.

Post-install tips for best results:

  • Use certified HDMI cables rated for 4K60 to ensure bandwidth is not constricted, especially when driving two 4K displays simultaneously.
  • For higher color accuracy and smoother gradients, enable HDR on compatible displays and content where supported by your hardware and software.
  • Check for Windows updates that may improve multimedia performance or USB-C/DP handling, ensuring your system runs with the latest compatibility fixes.
  • If you plan to use this hub with a laptop while on the go, ensure your laptop’s USB-C port provides sufficient power and supports MST to avoid throttling or reduced performance.

Frequently asked questions

Q: Does the SIIG 1x2 USB-C to HDMI 4K60 MST Hub Splitter require any drivers?

A: No driver installation is required on Windows PCs. It is designed to be plug-and-play, leveraging the host’s DP Alt Mode and MST support to drive two HDMI displays from a single USB-C connection.

Q: What resolutions can I expect on each monitor?

A: The hub supports dual 4K at 60 Hz on each HDMI output when the host and cables support the full bandwidth. Real-world performance depends on your USB-C port capability, DisplayPort version, and cable quality. If both displays fully support 4K60 and MST is properly configured, you can run two independent 4K60 displays.

Q: Which devices are compatible with this MST hub?

A: The hub is designed for Windows PCs with USB-C ports that support DisplayPort Alternate Mode and MST. It may work with other devices that provide DP Alt Mode over USB-C, but the description emphasizes Windows compatibility.

Q: Can I use this splitter to mirror my displays or must I extend the desktop?

A: You can configure the displays to either extend your desktop (recommended for multi-monitor productivity) or mirror the same content across both HDMI outputs, depending on your needs and the Windows Display Settings.

Q: Is external power required for operation?

A: The provided information does not specify an external power requirement. In most USB-C MST setups, external power is not required if the host USB-C port provides sufficient power and bandwidth. If you encounter stability issues, check your host port capabilities and consider testing with different USB-C cables.

Q: Can I use this hub with macOS or Linux?

A: The product description highlights Windows PCs as the primary compatibility target. While some USB-C MST hubs may function with other operating systems, official support is not guaranteed, and results may vary. For mission-critical setups, verify compatibility with your chosen OS before purchase.

Q: Will I be able to set each monitor to a different 4K setting?

A: Yes, provided your host GPU, MST configuration, and Display Settings support independent resolutions per display. You can set each HDMI output to its own preferred resolution within the supported 4K range, subject to system capabilities.

Q: What if I don’t see any display on one of the HDMI outputs?

A: First, ensure your USB-C port supports DP Alt Mode and MST, and confirm both HDMI cables and monitors are functioning. Then re-check Windows Display Settings to detect and configure both monitors. If needed, try different HDMI cables or outlets, and ensure the monitors are set to the correct input source.
