Troubleshooting

If you encounter issues with your AT-Mizhi Wireless HDMI Display Dongle Adapter, please refer to the following common solutions:

• No Display/Black Screen:
  • Ensure the dongle is securely plugged into the HDMI port.
  • Verify the display device is set to the correct HDMI input source.
  • Check the USB power connection. Ensure the dongle is receiving adequate power (use a 5V/2A adapter if available).
  • Try plugging the dongle into a different HDMI port or a different display device.
• Cannot Connect to Dongle's Wi-Fi:
  • Confirm you are selecting the correct MiraScreen network name and entering the default password "12345678".
  • Restart the dongle by unplugging and re-plugging its power source.
  • Ensure your device's Wi-Fi is enabled and functioning correctly.
• Lagging/Choppy Video or Audio:
  • Ensure the dongle is connected to a stable Wi-Fi network (if streaming online content).
  • Reduce the distance between your casting device and the dongle.
  • Minimize interference from other wireless devices.
  • Check if your home internet speed is sufficient for streaming.
  • For iOS devices, remember that some copyrighted content (HDCP) may not mirror smoothly or at all.
• Cannot Cast Specific Apps (iOS):
  • As mentioned, certain streaming services with HDCP protection (e.g., Netflix, Hulu, Prime Video) may block mirroring from iOS devices. This is a content protection measure, not a defect of the dongle.
• Dongle Overheating:
  • Ensure the dongle has adequate ventilation and is not covered.
  • Prolonged use, especially with high-resolution content, can cause the device to warm up, which is normal. If it becomes excessively hot, disconnect it and allow it to cool down.
