  1. Compatibility issues

Ensure that both your phone and computer support screen mirroring function. Different mobile phone and computer brands may support different screen projection methods, so it is necessary to check the information in the manual or official website. If your phone and computer support the same screen mirroring method but still cannot connect, you can try the following methods:

The screen mirroring function requires a stable network connection. If your network connection is unstable, it may cause screen mirroring to fail. You can try the following methods:

a. Ensure stable network connection: Check if your network connection is stable and try reconnecting to the network. If you are using a Wi Fi connection, you can try switching to another network or using a wired connection.

b. Use a stable Wi Fi network: Ensure that the Wi Fi network signal you are using is good and stable. If you are using a public Wi Fi network, you can try using a wired connection or a more stable Wi Fi network.

  1. Driver incompatibility or missing

Drivers are the bridge between the operating system and hardware devices. If the drivers are incompatible or missing, it may lead to screen mirroring failure. You can try the following methods:

a. Check drivers: Ensure that the drivers for your phone and computer are the latest version. If your device supports wireless screen mirroring, please ensure that the wireless network card driver is also the latest version.

b. Reinstall drivers: If your drivers have problems or are missing, you can try reinstalling them. Before reinstalling the driver, please backup your data just in case.

  1. Incorrect screen projection settings

Incorrect screen mirroring settings may result in screen mirroring failure. You can try the following methods:

a. Check screen mirroring settings: Check if the mirroring settings are correct on your phone and computer. Ensure that you have selected the correct screen projection method and target device. Meanwhile, ensure that you have enabled the required permissions and settings.

b. Manually add connection method: If your phone and computer cannot automatically connect, you can try manually adding a connection method. Open the “Settings” menu on the computer, find and click on the “Sound” option. In the sound options, find and click on the “Bluetooth” option. Then, turn on the Bluetooth function of the phone and set it to a searchable state. Wait for the computer to search for nearby Bluetooth devices, select your phone, and follow the prompts to connect. After successfully connecting, you should be able to see the screen content of your phone on your computer.
