Follow these steps to set up your Wireless Display Dongle Adapter:

1. Connect to Display: Plug the HDMI connector of the Wireless Display Dongle Adapter into an available HDMI port on your television, monitor, or projector.
2. Connect to Power: Connect the USB connection cable to the micro-USB port on the dongle and plug the other end into a USB power source (e.g., a USB port on your TV or a USB wall adapter). The device will power on.
3. Select Input: On your display device, select the corresponding HDMI input source to view the dongle's screen.
4. Connect Mobile Device to Dongle's Wi-Fi: On your mobile phone or tablet, go to your Wi-Fi settings. Find the Wi-Fi network broadcasted by the dongle (its name will typically appear on your display screen) and connect to it. If the network is not found, press and hold the small button on the dongle for approximately 15 seconds to reset it, then try again.
5. Configure 2.4G WLAN Network: Open a web browser on your mobile device. The dongle's configuration page should automatically appear. If not, refer to the on-screen instructions for the IP address. On this page, configure the dongle to connect to your home or office 2.4GHz Wi-Fi network. Note: Only 2.4GHz WLAN networks are supported.
6. Connect Mobile Device to Same WLAN: Ensure your mobile phone or tablet is now connected to the same 2.4GHz Wi-Fi network that you configured the dongle to use.

6. Operating Instructions

Once the setup is complete and both the dongle and your mobile device are connected to the same 2.4GHz Wi-Fi network, you can begin screen mirroring:

1. Activate Screen Transfer Function: On your mobile phone or tablet, locate and activate the screen mirroring, screen cast, or wireless display function. The exact name may vary depending on your device's operating system (e.g., Smart View, Screen Mirroring, Cast, Wireless Display, Miracast).
2. Select Dongle: From the list of available devices, select your Wireless Display Dongle Adapter.
3. Start Mirroring: Your mobile device's screen should now be mirrored on your connected display.

The dongle supports Full HD streaming with 1080p HD resolution, providing clear and vibrant images. It offers seamless screen casting with improved signal reinforcement and 5G dual-band speed-casting technology for minimal delay.

7. Troubleshooting

• No display on TV: Ensure the dongle is properly plugged into the HDMI port and receiving power via the USB cable. Verify that your TV input is set to the correct HDMI channel.
• Dongle Wi-Fi network not found: Press and hold the reset button on the dongle for 15 seconds. This will reset the device and it should then broadcast its Wi-Fi network.
• Cannot connect mobile device to dongle: Ensure both the dongle and your mobile device are connected to the same 2.4GHz Wi-Fi network. The dongle does not support 5GHz networks.
• Screen mirroring is laggy or disconnects: Ensure your Wi-Fi signal is strong and stable. Reduce the distance between your mobile device, the dongle, and your Wi-Fi router. Check for interference from other wireless devices.
