- Storage: When not in use, store the docking station in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Avoid dropping the device or subjecting it to strong impacts. Do not attempt to disassemble the docking station, as this will void the warranty.
5. Troubleshooting
If you encounter issues with your UGREEN 6-in-1 Docking Station, please refer to the following common solutions:
- No Video Output or Incorrect Resolution/Refresh Rate:
- Ensure your host device (e.g., Steam Deck, ROG Ally) and the connected monitor/TV both support the desired resolution and refresh rate (e.g., 4K@120Hz).
- Check that the HDMI cable is securely connected at both ends.
- Try a different HDMI cable or monitor to rule out external component issues.
- USB Peripherals Not Detected:
- For Steam Deck, ensure the device is in 'Desktop Mode' when attempting to use USB storage devices.
- Verify that the USB devices are properly inserted into the docking station's data ports.
- Note that the USB data ports do not support video output.
- Slow Charging or Insufficient Power:
- The docking station consumes some power for its own operation. For optimal charging of your console, use a USB-C PD charger with a higher wattage than the original charger that came with your console.
- Ensure the USB-C PD power adapter is securely connected to the dock's PD port.
- No Network Connection via Ethernet:
- Check that the Ethernet cable is securely connected to both the docking station and your router/modem.
- Verify that your network is functioning correctly.
- Device Not Fitting Securely:
