7. Troubleshooting
- No Signal on TV:
Ensure the adapter is correctly plugged into the HDMI port and powered via the USB-C cable. Select the correct HDMI input channel on your TV. Try a different HDMI port or USB power source. - Connection Issues:
If using Direct Connect mode, ensure your device's screen mirroring function is active and selecting the correct adapter name. If using DLNA mode, verify the adapter is connected to your Wi-Fi router and your device is on the same network. Try restarting both your device and the adapter. - Lag or Choppy Video:
Ensure the adapter is within the recommended 65ft (20m) range of your device. Minimize interference from other wireless devices. If using DLNA mode, ensure your Wi-Fi network is stable and has good signal strength. The adapter supports 5G WiFi for better performance. - No Audio:
Check the audio output settings on your source device and ensure the TV/monitor volume is up. - Cannot Cast Certain Apps (iOS/MacBook):
Some streaming services (e.g., Netflix, Prime Video) use HDCP protection, which prevents mirroring on iOS/MacBook devices. This is a content protection feature and not a defect of the adapter. - Factory Reset:
