Setup Instructions

1. Identify Ports: Confirm that your source device (e.g., Raspberry Pi Zero, DSLR camera) features a Mini HDMI Type C port. This adapter is not compatible with Micro HDMI Type D, USB-C, or full-size HDMI ports. Refer to the compatibility guide image below for visual identification.
2. Connect to Source Device: Insert the Mini HDMI (male) end of the adapter into the Mini HDMI Type C port on your source device.
3. Connect HDMI Cable: Attach a standard HDMI cable (sold separately) to the full-size HDMI (female) port on the adapter.
4. Connect to Display: Connect the other end of the standard HDMI cable to an available HDMI input port on your display device (e.g., TV, monitor, projector).
5. Power On Devices: Ensure both your source device and your display are powered on. Select the correct HDMI input on your display using its remote or menu.

Important: To achieve 8K@60Hz or 4K@240Hz resolutions and utilize advanced HDMI 2.1 features, all components in your setup (source device, HDMI cable, and display) must support the required specifications.

Operating Instructions

Once properly connected, the adapter functions as a direct pass-through for video and audio signals. No additional drivers or software installation is required for its operation.

• Video Output: The adapter will transmit video from your Mini HDMI source device to your HDMI display. The actual resolution and refresh rate achieved will depend on the capabilities of your source device, the quality of your HDMI cable, and your display.
• Audio Output: Digital audio signals will be transmitted through the HDMI connection to your display or any connected audio system.
• Advanced Features: If your connected equipment supports HDMI 2.1 features such as HDR, VRR, ALLM, or eARC, these functionalities will be automatically enabled through the adapter.

For optimal visual and audio performance, ensure that all connected devices are configured to their highest compatible resolution and refresh rate within their respective display or sound settings.

Maintenance

This adapter is designed for durability and requires minimal maintenance to ensure long-term performance.

• Cleaning: Use a soft, dry, lint-free cloth to gently clean the adapter. Avoid using liquid cleaners, abrasive materials, or chemical solvents, as these can damage the product.
• Storage: When not in use, store the adapter in a cool, dry environment, away from direct sunlight, excessive heat, or extreme cold.
• Handling: Always handle the adapter by its connectors when plugging in or unplugging. Avoid sharply bending the cable or applying excessive force, which can lead to internal wire damage or connector failure.

Troubleshooting

No Video/Audio Signal:

• Ensure all cable connections are secure between the source device, the adapter, and the display.
• Verify that the correct input source (HDMI port) is selected on your display device.
• Test with a different standard HDMI cable to rule out potential cable defects.
• Confirm that your source device is powered on and configured to output a video signal.
• Double-check that your source device has a Mini HDMI Type C port, not a Micro HDMI Type D or other incompatible port.

Low Resolution or Incorrect Refresh Rate:

• Ensure that your source device, the standard HDMI cable, and your display all support the desired resolution and refresh rate (e.g., 8K@60Hz, 4K@240Hz).
• Update the graphics drivers on your source device (if applicable, such as a PC or laptop).
• Adjust the display settings on your source device to output the preferred resolution and refresh rate.

Intermittent Signal or Flickering Screen:

• Check for any loose connections at the adapter, source device, or display.
• Ensure the standard HDMI cable used is not excessively long or of insufficient quality for the bandwidth required by your resolution and refresh rate.
• Minimize electromagnetic interference by keeping the adapter and cables away from other electronic devices that may emit strong signals.
