SIIG 1x3 DisplayPort 1.4 to DisplayPort MST Splitter

Unlock expansive multi-monitor capabilities with the SIIG 1x3 DisplayPort 1.4 MST Splitter. This compact MST hub takes a single DisplayPort 1.4 output and splits it into up to three independent DisplayPort streams using Multi-Stream Transport (MST), enabling extended desktops, video walls, and immersive workflows without the clutter of multiple cables or additional power requirements. Designed for professionals who demand crisp 4K clarity, fluid motion, and easy setup, this splitter leverages the full bandwidth of DisplayPort 1.4 (32.4 Gbps) to deliver high-resolution performance across multiple displays. With a driverless, plug-and-play design, it is compatible with modern GPUs and DP-enabled systems, making it ideal for creative workstations, trading desks, digital signage, classrooms, and professional AV installations. Whether you’re building a productivity workstation, editing suite, or immersive presentation setup, the SIIG MST Splitter provides a reliable foundation for scalable, high-quality video output.

• Connect up to three DisplayPort displays from a single DP 1.4 source using Multi-Stream Transport (MST), expanding your desktop and application space without adding extra graphics cards.
• Triple DisplayPort outputs support flexible configurations: Dual 4K@60Hz or Triple 4K (4K@30Hz per display), or 1x 4K@60Hz + 2x 4K@30Hz, offering a range of performance options to suit your workload and GPU headroom.
• No driver required — plug-and-play with DP-enabled systems for quick setup and minimal IT overhead.
• Backward compatible with DisplayPort 1.2 with limited performance, enabling legacy systems to benefit from MST expansion where available.
• High bandwidth of 32.4 Gbps preserves image quality, color accuracy, and smooth motion across all connected displays, even at 4K resolutions.

How to Install SIIG 1x3 DisplayPort 1.4 MST Splitter

• Connect your DisplayPort 1.4 source (GPU or DP-enabled PC) to the MST splitter input using a DisplayPort cable.
• Attach DisplayPort cables from the splitter to up to three displays on their DP inputs.
• Ensure your system supports MST and DP 1.4; enable MST mode or Extended Desktop in your operating system if required.

• Configure the displays in your operating system to Extend or Mirror as desired; select 4K resolutions where supported (prefer 4K@60Hz per display when headroom allows).

Frequently asked questions

• What is Multi-Stream Transport (MST)? MST allows a single DisplayPort connection to carry multiple independent video streams, enabling multiple displays to be driven from one DP output.
• Do I need drivers to use this splitter? No. The SIIG MST Splitter is driverless and designed for plug-and-play use on DP-enabled systems.
• How many 4K displays can I run at once? Depending on configuration, you can run Dual 4K@60Hz or Triple 4K at 30 Hz each, or 1x 4K@60Hz + 2x 4K@30Hz, within the limits of DP 1.4 bandwidth and GPU capabilities.
• Is it backward compatible with DisplayPort 1.2? Yes, it offers limited performance in DP 1.2 environments, enabling older systems to benefit from MST expansion where possible.
• Is external power required? No. The device is designed to operate without an external power supply, drawing power from the DP source.
• What setups is this MST splitter best suited for? It’s ideal for multi-monitor workstations, content creation, data analytics dashboards, financial trading desks, digital signage, classrooms, and immersive AV presentations where screen real estate and synchronization across displays matter.
