7. Operating Instructions
Display Modes:
- Mirror Mode: Your device's screen will be duplicated on the external HDMI display. This is useful for presentations or sharing content.
- Extend Mode: The external HDMI display will act as a separate screen, allowing you to display different content or extend your desktop workspace. This mode is ideal for multitasking.
To switch between display modes, access your device's display settings (e.g., System Preferences on macOS, Display Settings on Windows, or similar options on mobile devices).
Charging Functionality:
The dedicated USB-C PD port allows you to charge your source device (laptop, tablet, phone) at up to 100W while simultaneously using the HDMI display. Ensure you use a compatible USB-C charging cable and power adapter (not included) to utilize this feature.


8. Maintenance
To ensure the longevity and optimal performance of your UGREEN USB C to HDMI Cable:
- Avoid bending the cable sharply or applying excessive force to the connectors.
- Store the cable in a clean, dry environment when not in use.
- Clean the connectors periodically with a soft, dry cloth to remove dust or debris.
- Do not expose the cable to extreme temperatures or direct sunlight.
9. Troubleshooting
No Signal on Display:
- Ensure both the USB-C and HDMI connectors are fully inserted into their respective ports.
- Verify that your source device's USB-C port supports "DP Alt Mode" for video output.
- Check the input source selection on your TV/monitor to ensure the correct HDMI port is selected.
- Try connecting the cable to a different HDMI port on your display or a different display altogether.
- Restart your source device.
Charging Not Working:
- Ensure you are using a compatible USB-C charging cable and a power adapter that supports Power Delivery (PD).
- Verify that the charging cable is securely connected to the UGREEN adapter's PD port and the power source.
- Confirm that your power adapter provides sufficient wattage (up to 100W supported by the adapter).
Flickering or Unstable Display:
- Ensure the cable is not damaged and connections are secure.
- Try reducing the display resolution or refresh rate in your device's display settings.
- Ensure your display device and source device drivers are up to date.
10. Important Notes
- This cable is unidirectional, meaning it only transmits signals from a USB-C source device to an HDMI display. It cannot be used in reverse (HDMI to USB-C).
- The USB-C PD charging cable and wall adapter are not included with this product.
- For optimal 4K@60Hz performance, ensure your source device and display both support this resolution and refresh rate.
