• Handling: Avoid sharp bends, twists, or excessive pulling on the cables, especially near the connectors, to prevent internal wire damage.
• Connection: Always grasp the connector head when plugging or unplugging the cable, rather than pulling on the cable itself.
• Environment: Keep the cables away from extreme temperatures, direct sunlight, and moisture.

6. Troubleshooting

If you encounter issues with your AOHI 4-in-1 USB4 Cable Set, refer to the following common troubleshooting steps:

6.1 Charging Issues

• No Charging/Slow Charging:
  • Ensure both your power adapter and device support the required Power Delivery (PD) protocol and wattage.
  • Verify that the cable is securely connected at both ends.
  • Test with a different power adapter or device to isolate the issue.
  • Note that the actual maximum charging speed depends on the power supported by your charging device and charger.

6.2 Data Transfer Issues

• Slow Data Transfer/No Data Transfer:
  • Confirm that both connected devices (e.g., computer and external drive) support the desired USB standard (USB4.0 for 40Gbps, USB 3.2 Gen 2 for 10Gbps).
  • Ensure the cable is fully inserted into both ports.
  • Try connecting to a different port on your computer or using a different device.

6.3 Video Output Issues

• No Video/Low Resolution:
  • Video output is only supported via USB-C to USB-C connections. Ensure you are using the correct cable type.
  • Verify that your source device (laptop) and display both support the desired resolution (e.g., 8K@60Hz).
  • Check display settings on your computer to ensure the external monitor is detected and configured correctly.
  • The maximum pixel output depends on your output device's capabilities.

6.4 Thunderbolt 4 Compatibility

• Note: This USB4 cable is not fully compatible with Thunderbolt 4. If connected to a Thunderbolt 4 device, performance specifications may be downgraded to Thunderbolt 3. Intermittent connection issues may occur with Thunderbolt 3 devices.
