5. Troubleshooting
If you encounter any issues with your BRAIDOL Wireless HDMI Display Dongle Adapter, please refer to the following common problems and solutions:
- No boot screen, no signal: Check if the HDMI port connected to the device is the correct input source on your TV. Ensure the display device's USB port provides sufficient power (5V/1A). If not, use the provided AC adapter.
- Screen freezes/delays during mirroring: Verify the power supply is 5V/1A. Check if the Wi-Fi channel connected to your mobile phone is the same as the device. Strong interference from microwaves, induction cookers, or other household appliances can affect wireless transmission. Try changing the Wi-Fi channel of your router.
- Unable to find the product in the mobile Wi-Fi list: Ensure the product is in the correct iOS/Android/Windows mode. In iOS/Mac mode, the product will not transmit Wi-Fi signals. Also, confirm the power supply meets specifications.
- Laptop prompts "unable to connect" or "device does not respond": Ensure your laptop meets the minimum requirements: Intel processor, Intel graphics, Intel wireless network, and Windows 8.1 or above operating system.
- After mirroring, some video apps have sound but no video signal: This is typically due to HDCP copyright protection. Close the app in the background of your mobile phone, then re-select the mirroring mode. After mirroring is completed, open the video app again.
- Mobile phone system has been upgraded and product is not working: A new version of the firmware for the mobile phone version upgrade will be released. Just set the product connected to an available network, and the product will automatically download the new firmware and install it.
