How to install StarTech.com Dual-Monitor DisplayPort 1.2 Splitter

Follow these steps to set up dual-monitor output from a single DisplayPort 1.2 source:

Step 1: Verify compatibility. Ensure your computer has a DisplayPort 1.2-capable graphics card or display adapter and that the GPU drivers are up to date. This device relies on MST capabilities provided by DP 1.2 to split the signal across two displays.

Step 2: Connect the MST hub to your source. Use a DisplayPort cable to connect the DisplayPort 1.2 output on your laptop or desktop to the input on the StarTech MST hub. Make sure the connection is secure and the hub is powered (if required by your setup).

Step 3: Attach your monitors. Connect each monitor to one of the two DisplayPort outputs on the MST hub using DisplayPort cables. Verify that both monitors are powered on and set to their native resolutions where possible.

Step 4: Configure display settings in Windows. Right-click the desktop and select Display settings. Choose Extended Desktop or Mirror, depending on your preference, and arrange the displays to match their physical positions. If you are running 4K monitors, configure each display to 3840x2160 at 30 Hz (or the supported resolution) for optimal clarity.

Step 5: Optimize performance. Update your graphics drivers and Windows to the latest version to ensure MST functionality and resolution handling are fully supported. If you encounter any issues, check the GPU control panel for MST-specific options and ensure that the DisplayPort connections are secure.

Step 6: Fine-tune color and scaling. Depending on your workflow, you may want to adjust color profiles, brightness, and scaling per display to achieve consistent visuals across both screens, especially in design, video, and data-intensive tasks.

Frequently asked questions

• How many displays can I run with this splitter? You can run two displays from a single DisplayPort 1.2 source using the MST hub.
• What resolutions are supported? Each display can reach up to 4K (3840x2160) at 30Hz when using a DP 1.2 MST-capable source. Depending on GPU and driver capabilities, higher refresh rates may be possible on certain configurations.
• Do I need drivers to use this device? For basic operation on Windows, no additional driver installation is typically required. For advanced MST configurations and best compatibility, ensure your graphics drivers and Windows are up to date.
• Is this compatible with non-Windows systems? The product is designed for Windows environments; compatibility with other operating systems may vary and is not guaranteed by StarTech.
• Can I mirror the displays or extend my desktop? Yes. The MST hub supports both extended desktop and mirror (duplicated) modes, allowing you to tailor your setup to presentations or collaborative work.
