8. Troubleshooting
If you encounter issues with your docking station, please refer to the following common troubleshooting steps:
- No Display Output:
- Ensure all cables (HOST, HDMI/USB4 Downstream) are securely connected.
- Verify that your display device and cables support the desired resolution and refresh rate (e.g., 8K/60Hz).
- Check your computer's display settings to ensure the external monitor is detected and configured correctly (Mirror or Extended mode).
- Confirm your computer's ports (Thunderbolt/USB4) are functioning correctly.
- For Mac users, check your specific M-series chip's external display limitations.
- Slow Data Transfer Speed:
- Ensure you are using the provided full-featured USB4 cable for the HOST connection.
- Verify that the connected peripherals (e.g., external hard drives) support 10Gbps or higher speeds.
- The total bandwidth is 40Gbps. If multiple high-bandwidth devices are connected simultaneously, performance may be affected.
- No Charging / Slow Charging:
- Ensure a PD 100W power adapter is connected to the docking station's PD 100W port.
- Verify that your host device supports USB-C Power Delivery.
- The docking station provides up to 80W (MAX) to the host after its own 20W consumption. Ensure this is sufficient for your laptop's charging requirements.
- Docking Station Not Recognized:
- Disconnect and reconnect the HOST cable.
- Try connecting the docking station to a different Thunderbolt 4/5 or USB4 port on your computer.
- Restart your computer.
- Ensure your computer's drivers are up to date.
9. User Tips
- Optimal Performance: For optimal performance, ensure your host device has Thunderbolt 4/5 or USB4 ports that support 40Gbps bandwidth and DP1.4. If your host only has 10Gbps USB-C (DP1.2), docking station performance will be reduced accordingly.
- Cable Quality: Always use high-quality, full-featured cables for both host connection and display output to ensure stable performance and maximum resolution.
- Power Adapter: Invest in a reliable 100W PD charger to fully utilize the charging capabilities of the docking station and ensure stable power delivery to all connected devices.
