5. Operating Instructions

Screen Mirroring / Extended Display

Once paired, your device will automatically mirror your source screen. To switch between mirroring and extended display modes (if supported by your operating system), adjust your display settings on your source device (e.g., Windows Display Settings or macOS System Preferences).

7. Troubleshooting

If you encounter issues, please refer to the following common solutions:

• No Signal or Intermittent Connection:
  • Ensure both the transmitter and receiver are connected to a stable power source (5V/1A or above charger). Insufficient power can cause interruptions or lag.
  • Check that the HDMI cables are securely connected.
  • Verify that the display is set to the correct HDMI input.
  • If in different rooms or separated by thick walls, the transmission distance may be reduced. Try moving devices closer or ensuring a clear line of sight.
  • Re-pair the transmitter and receiver if the connection is lost or unstable.
• Lag or Stuttering Video:
  • Ensure adequate power supply to both units.
  • Reduce the distance between the transmitter and receiver.
  • Minimize interference from other wireless devices operating on the same frequency band (2.4G/5Ghz).
• No Audio:
  • Check audio settings on your source device and display.
  • Ensure the HDMI connection is secure.
