Troubleshooting

If you encounter issues with your adapter, please refer to the following common troubleshooting steps:

• No Display Output:
  • Ensure your device's Type-C port supports video output. Not all USB-C ports are designed for this functionality.
  • Verify that the adapter is securely connected to both your source device and the HDMI display.
  • Check the HDMI cable for damage and ensure it is properly connected.
  • Confirm that the display input source is set correctly (e.g., HDMI 1, HDMI 2).
  • Restart your source device (laptop/phone).
• No Charging via USB-C PD Port:
  • Ensure your power adapter and USB-C charging cable are functional and properly connected to the adapter's Type-C female port.
  • Verify that your power adapter provides sufficient wattage (5W-60W) for your device.
• USB 3.0 Port Not Working:
  • Ensure the USB device is properly inserted into the USB 3.0 port.
  • Test the USB device directly with your source device to rule out device issues.
• Compatibility Issues:
  • The converter only works with phones or laptops that have a Type-C port supporting HDMI video output. It will not work with devices lacking this feature.
  • The converter cannot transfer image/video data directly between a phone and a laptop; it only transfers from a phone to a monitor or from a laptop to a monitor.
  • Some Samsung phones may require an additional MHL (Mobile High-definition Link) HDMI converter to connect with the phone.
  • For specific device compatibility (e.g., Huawei, iPad, Samsung, Blackshark, RedMagic, LG, Microsoft, OnePlus), please refer to the official website of your device's brand to confirm if its Type-C port has full functionality for video output.
