Important Compatibility Note

This adapter is a uni-directional cable, meaning it converts from a USB-C source to an HDMI display. It is crucial to note that not all USB-C interfaces are compatible. The adapter only functions with USB-C 3.1 or Thunderbolt 3 port interfaces that support "DisplayPort Alternate Mode" (Alt Mode). Please verify your device's USB-C port specifications before use.

Troubleshooting

No Display/Signal:

• Ensure your source device's USB-C port supports "DisplayPort Alternate Mode". This is the most common reason for no signal.
• Verify that the HDMI cable is securely connected to both the adapter and the display device.
• Check that the display device is set to the correct HDMI input source.
• Try connecting the adapter to a different USB-C port on your source device, if available.
• Test with a different HDMI cable, especially if aiming for 4K resolution (ensure it's an HDMI 2.0 cable).
• Restart your source device.

Low Resolution/Flickering Display:

• Ensure your HDMI cable is capable of supporting the desired resolution (e.g., HDMI 2.0 for 4K@30Hz).
• Check your source device's display settings to ensure the output resolution is set correctly.
• Verify that your display device supports the desired resolution.

No Audio:

• Ensure your display device's volume is turned up and not muted.
• Check your source device's audio output settings to ensure audio is being routed through the HDMI output.
