Common problems and solutions
- Unable to find TV device: Ensure that the TV is switched to the correct HDMI channel and check if the connection between the computer and TV is stable. Also, restart the computer and TV device, and then try connecting again.

Ensure that the audio cable is properly connected and set the corresponding audio output settings on the computer and TV. If the problem persists, you can try using other audio output methods, such as Bluetooth or wireless audio devices.
- Operating system updates: Operating system updates may affect the use of screen mirroring functionality. Before casting, make sure your operating system has been updated to the latest version to achieve the best screen casting effect. If the issue persists after the update, you can try reinstalling the graphics card driver or contacting technical support for assistance.
During the screen casting process, attention should be paid to details such as hardware device connections, operating system updates, and screen casting method adjustments.
