Frequently asked questions

What is MST? Multi-Stream Transport (MST) is a DisplayPort technology that allows multiple independent displays to be driven from a single DisplayPort 1.2 output. By splitting the bandwidth across two monitors, MST splitters enable extended desktops, mirrored displays, and more flexible multi-monitor setups without sacrificing performance.

Will this splitter work with any DisplayPort monitor? Yes. The splitter is designed to work with DisplayPort-enabled displays that support DP 1.2 MST. For the best results, ensure your monitors support the required resolution and refresh rates your workflow demands.

Do I need drivers for this device? In most cases, this device is plug-and-play and does not require special drivers. Some operating systems may require you to adjust display settings after connecting to configure the layout, resolution, and orientation.

Can I use HDMI displays with this splitter? This product is a DisplayPort MST splitter. To drive HDMI displays, you would typically need additional adapters (e.g., DP to HDMI) on each output, which may impact supported resolutions and performance. Refer to your monitor specifications and adapters for compatibility.

Does it support 4K on both displays simultaneously? The splitter supports high-resolution output across two displays via MST. Maximum practical resolutions depend on the displays, their capabilities, and bandwidth constraints of DisplayPort 1.2. In many setups, you can achieve high-resolution output on both displays, often up to 4K on each display with appropriate hardware and cables.

Is external power required? The device is typically designed for a bus-powered configuration, drawing power from the host through the DP connection. In some setups or with certain monitors, external power may be unnecessary, but if you experience instability, consult the user manual for power options and compatibility with your GPU or laptop.

Can I use this splitter for gaming or professional design work? Yes. The SIIG 4K 1x2 DisplayPort MST Splitter is suitable for gaming, video editing, graphic design, and other professional tasks that benefit from dual-monitor setups. For gaming, ensure your GPU and monitors can handle the target resolution and frame rate across both displays, as this involves more bandwidth than a single display configuration.

What should I consider when choosing cables? Use high-quality DisplayPort cables that support DP 1.2 specifications and the resolutions you intend to run. Poor-quality or long cables can introduce signal degradation, causing flicker or unstable displays. Shorter, well-shielded cables typically yield the best results in dual-monitor configurations.

How do I adjust display arrangement in Windows/macOS? After connecting the splitter, go to your operating system’s display settings. In Windows, use Settings > System > Display to extend or mirror, and drag the monitor icons to reflect their physical positions. In macOS, open System Preferences > Displays and configure the Arrangement tab to set the relative positions and alignment of the displays.
