4. Setup Instructions

Follow these steps to correctly set up your UANTIN DisplayPort Splitter:

1. Connect the Source: Plug the DisplayPort connector of the splitter into the DisplayPort output of your signal source (e.g., PC, graphics card).
2. Provide Power: Connect the included USB power cable to the splitter's Micro Port and then to a 5V/1A power source (e.g., a USB port on your computer or a USB wall adapter). This power connection is essential for the splitter to function correctly.
3. Connect Monitors: Connect your three DisplayPort monitors to the three DP female output ports on the splitter using DisplayPort extension cables that support 4K@60Hz.

Important Notes:

• Ensure your graphics card supports at least 18Gbps bandwidth for 3-monitor extended mode.
• PCs with integrated GPUs may only support mirroring mode or extend to a single additional monitor.
• This splitter cannot be used with any hub, docking station, or KVM switch.
• This device is not compatible with HDMI source devices or HDMI port laptops. Ensure your source device has a DisplayPort output.

5. Operating Modes

The UANTIN DisplayPort Splitter supports two primary display modes:

• Mirroring Mode (SST - Single Stream Transport): In this mode, all connected monitors display the same content as your primary screen. This is useful for presentations or sharing content across multiple displays.
• Extended Mode (MST - Multi-Stream Transport): This mode allows each connected monitor to display different content, effectively extending your desktop workspace across multiple screens. This is ideal for multitasking and increasing productivity.

To configure these modes, access your operating system's display settings (e.g., Windows Display Settings, NVIDIA Control Panel, AMD Radeon Settings) and select the desired display arrangement.

6. Troubleshooting

If you encounter issues with your DisplayPort splitter, please refer to the following common problems and solutions:

• No Display or Intermittent Signal:
  • Check Power Connection: Ensure the included USB power cable is securely connected to the splitter and a 5V/1A power source. The splitter requires external power to function.
  • Verify Cable Connections: Confirm all DisplayPort cables are firmly seated in both the splitter and your monitors/source device.
  • Graphics Card Bandwidth: For extended display across three monitors, your graphics card must support sufficient bandwidth (18Gbps or more). Older or integrated graphics cards may have limitations.
  • Resolution Compatibility: Ensure your input and output devices (graphics card and monitors) both support the desired resolution and refresh rate. Refer to the Resolution Reference Table in Section 3.
  • Restart Devices: Try restarting your computer and monitors after connecting the splitter.
• Monitors Flashing or Going Black Randomly:
  • This often indicates insufficient power or bandwidth. Double-check the power connection and ensure your graphics card meets the bandwidth requirements.
  • Try using high-quality DisplayPort cables.
  • Reduce the resolution or refresh rate of your monitors to see if the issue persists.
• Only Mirroring Mode Available / Cannot Extend Display:
  • Verify your graphics card supports MST (Multi-Stream Transport). Some older graphics cards or integrated GPUs may only support SST.
  • Check your operating system's display settings to ensure "Extend these displays" is selected.
• Incompatible with Hubs/Docking Stations/KVMs:
  • The UANTIN DisplayPort Splitter is designed for direct connection to a DisplayPort source. It is not intended for use in conjunction with other display hubs, docking stations, or KVM switches.
• Not Working with HDMI Devices:
  • This splitter is for DisplayPort connections only. It will not work with HDMI source devices or laptops that only have HDMI outputs.

7. Maintenance

To ensure the longevity and optimal performance of your UANTIN DisplayPort Splitter, follow these simple maintenance guidelines:

• Keep the device in a cool, dry place, away from direct sunlight and extreme temperatures.
• Avoid exposing the splitter to water or excessive moisture.
• Clean the device with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
• Handle cables and connectors gently to prevent damage. The DisplayPort plug features a non-locking design to prevent damage during unplugging.
