4. Setup Instructions (Plug & Play)

The Lemorele Wireless HDMI Extender is designed for easy plug-and-play setup without the need for additional drivers or apps.

1. Connect the Receiver (RX): Connect the receiver's HDMI or VGA port to a display device such as a TV, monitor, or projector.
2. Connect the Transmitter (TX): Connect the transmitter to your computer or other video output device.
3. Power the Devices: Ensure both the TX and RX units are adequately powered. If the transmitter's indicator light is flashing, its voltage is insufficient. Use the supplied power supply cable to power the transmitter (Power supply voltage: 5V2A).
4. Initiate Pairing: Press and hold the function key of the transmitter (TX) for more than 3 seconds. The indicator light of the transmitter will flash rapidly, entering pairing mode.
5. Confirm Connection: Wait for the transmitter's indicator light to become solid. A solid light indicates a successful connection and mirroring is active.

5. Operating Modes

5.1 Mirror and Extend Mode

The wireless transmission supports both mirroring and extending your display. You can wirelessly stream 1080P content from your laptop to a single or dual monitor setup. This flexibility is beneficial for presentations, multitasking, or simply enjoying content on a larger screen.

• Mirror Mode: Duplicates your source device's screen onto the connected display.
• Extend Mode: Expands your desktop workspace across the source device and the connected display.

Note: Mobile phones and tablets typically use mirroring mode, utilizing only the receiver for display.

5.2 Multi-Point Free Switching

This kit supports connecting up to 8 transmitters to a single receiver, allowing for easy switching between multiple source devices. This feature is particularly useful in collaborative environments like conference rooms or classrooms.

6. Troubleshooting

• No Signal/Black Screen:
  • Ensure both the transmitter (TX) and receiver (RX) are properly connected and powered on.
  • Verify that the display device is set to the correct HDMI or VGA input source.
  • Check if the transmitter's indicator light is solid. If it's blinking, the power supply might be insufficient. Use the provided 5V2A power adapter.
• Pairing Failure:
  • Ensure the TX and RX units are within the effective transmission range (up to 50 meters).
  • If pairing consistently fails, try resetting the receiver to factory settings by pressing and holding the receiver's function button for 10 seconds. Then, attempt the pairing process again.
• Intermittent Connection/Lag:
  • Ensure there are no significant obstructions (thick walls, metal objects) between the transmitter and receiver.
  • Minimize interference from other 5GHz Wi-Fi devices.
  • Check the power supply for both units to ensure stable operation.
• No Audio:
  • Verify that the audio output settings on your source device are correctly configured.
  • If using the RX's audio output port, ensure external speakers or headphones are properly connected.
