    • Check the mobile device manual or contact the manufacturer for further details.
    • Make sure there are no other wireless devices connected to the mobile device prior to the TV's screen mirroring setup.
    • If you connected your TV to a computer, a Microsoft® Windows® 10 operating system upgraded from an earlier version may not be compatible. Contact the computer manufacturer for further details.

  • Both the 2.4 GHz and 5 GHz frequency band available on most wireless routers are prone to channel interference. Ask your internet service provider to help you set your router to a non-overlapping channel.
  • If your wireless router supports both 2.4 GHz and 5 GHz frequency band, setting the frequency band to 2.4GHz may resolve the issue.
  • Other mobile devices simultaneously connected to your wireless router may affect the screen mirroring function. Disconnect other mobile devices from the router.
