4. Setup Instructions

Follow these steps to set up your UGREEN Wireless HDMI Extender Kit:

1. Transmitter Connection: Connect the HDMI interface of the transmitter to your source device (e.g., laptop, PC). Connect a USB-C power cable to the transmitter's USB-C port and plug it into a power source (e.g., computer's USB port or a USB power adapter).
2. Receiver Connection: Connect the receiver to your display device using either an HDMI or VGA cable. Connect a USB-C power cable to the receiver's USB-C port and plug it into a power source.
3. Signal Source Selection: On your display device (TV, monitor), select the corresponding HDMI or VGA input source that the receiver is connected to.
4. One-Click Connection: Once both the transmitter and receiver are powered on and connected, click the button on the transmitter. The devices will automatically connect, and your content should appear on the display.

Important: Both the transmitter and receiver require external power via their USB-C ports for proper operation.

5. Operating Modes

The UGREEN Wireless HDMI Extender supports two primary display modes:

5.1 Mirror Mode

In Mirror Mode, the content displayed on your source device (e.g., laptop screen) is duplicated on the external display connected to the receiver. This is useful for presentations or sharing content directly.

5.2 Extended Mode

In Extended Mode, the external display acts as an extension of your source device's desktop, allowing you to have different content on each screen. This is beneficial for multitasking and increasing productivity.

7. Troubleshooting

If you encounter issues with your Wireless HDMI Extender, please refer to the following common problems and solutions:

7.1 No Signal or Disconnection

• Check Power: Ensure both the transmitter and receiver are properly powered via their USB-C ports.
• Cable Connections: Verify that all HDMI/VGA cables are securely connected to both the source and display devices.
• Display Input: Confirm that your display device is set to the correct HDMI or VGA input source.
• Re-pair Devices: Press the one-click connection button on the transmitter to re-establish the wireless link.
• Distance/Obstacles: Ensure the transmitter and receiver are within the 50-meter range and there are no significant physical obstructions (e.g., thick walls) that could interfere with the wireless signal.
• Interference: Other wireless devices operating on 2.4GHz or 5GHz bands might cause interference. Try to minimize other wireless activity or adjust the position of the extender.

7.2 Video Lag or Delay (Latency)

• While the device is designed for low latency (as low as 0.1S), environmental factors or heavy network traffic can affect performance.
• Reduce Distance: Try placing the transmitter and receiver closer to each other.
• Minimize Interference: As mentioned above, reduce other wireless interference.
• Check Source/Display: Ensure your source device and display are functioning optimally and not causing delays themselves.

7.3 No Audio (when using VGA)

• When using the VGA output, a separate 3.5mm audio cable must be connected from the receiver to an audio device (e.g., speakers, soundbar) to achieve synchronous audio transmission. VGA itself does not carry audio.

8. User Tips

• Power Supply is Crucial: Always ensure both the transmitter and receiver are connected to a stable power source via their USB-C ports. Insufficient power is a common cause of connection issues or instability.
• Transmitter vs. Receiver: The round unit is the Transmitter (connects to the source), and the rectangular unit is the Receiver (connects to the display). They are distinct and not interchangeable in function.
• Dolby Atmos/Vision: This extender primarily focuses on video and standard audio transmission. Dolby Atmos and Dolby Vision are not explicitly supported in the specifications, so advanced audio/video formats may not pass through.
• Optimal Placement: For the best wireless performance, try to place the transmitter and receiver in a line of sight or with minimal obstructions. Avoid placing them behind large metal objects or near other strong wireless signals.

9. Maintenance

To ensure the longevity and optimal performance of your UGREEN Wireless HDMI Extender Kit, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the surfaces of the devices. Do not use liquid cleaners or aerosols, as they may damage the components.
• Storage: When not in use for extended periods, store the devices in a cool, dry place away from direct sunlight and extreme temperatures.
• Handling: Handle the devices with care. Avoid dropping them or subjecting them to strong impacts.
• Ventilation: Ensure the receiver (rectangular unit) has adequate ventilation, especially during prolonged use, as it contains electronic components that generate heat. The thoughtful design includes a better cooling effect and metal material for heat dissipation.
