Troubleshooting

  • No Display Output:
    • Ensure your laptop's USB-C port supports DisplayPort Alt Mode.
    • Check all cable connections between the docking station, laptop, and monitors.
    • Verify that your monitors are set to the correct input source (HDMI 1, HDMI 2, or DP).
    • Try connecting one monitor at a time to isolate the issue.
    • Restart your laptop and the docking station.
  • Charging Issues:
    • Confirm the 140W power adapter is securely connected to the DC-IN port and a working power outlet.
    • Ensure your laptop supports USB-C Power Delivery for charging via the upstream port.
    • Note the combined power output limit (100W total) if charging multiple devices simultaneously.
  • Slow Data Transfer Speeds:
    • Ensure you are using the 10Gbps USB-A 3.2 Gen2 or USB-C 3.2 Gen2 ports for high-speed devices.
    • Check that your connected device (e.g., external SSD) also supports USB 3.2 Gen2 speeds.
  • Ethernet Connection Problems:
    • Verify the Ethernet cable is properly connected to both the docking station and your router/modem.
    • Check your laptop's network settings to ensure the wired connection is recognized and enabled.
    • Restart your router/modem and the docking station.
  • macOS Multi-Display Behavior:
    • Remember that macOS will mirror content across multiple external displays when connected to this docking station. This is a system limitation, not a defect of the product.

User Tips

  • Verify Laptop USB-C Port: Before purchasing or setting up, always confirm your laptop's USB-C port supports Power Delivery and DisplayPort Alt Mode for full functionality. Refer to your laptop's specifications.
  • Optimal Power: Always use the included 140W GaN power adapter to ensure stable operation and sufficient power delivery to all connected devices, especially for high-power laptops and multiple displays.
  • Cable Management: Utilize the compact design and various placement options (horizontal/vertical) to organize your cables and maintain a tidy workspace.
