Unable to start the Screen mirroring feature of the Blu-ray player.

Refer to the contents below to check the specifications, check the notes, reconfirm the settings, and troubleshoot.

• Checking whether your mobile device supports Miracast technology
  This feature uses Miracast technology to create a direct wireless connection between your device and the Blu-ray player.
  Your device must support Miracast (Screen mirroring) for this feature to work.
  
  NOTE: Miracast technology is a type of communication technology that was developed by the Wi-Fi Alliance and allows compatible devices to form a direct wireless connection and transmit videos.
  
• • If using an iOS
    Because iOS devices do not support Miracast, they cannot perform Screen mirroring.
    The inability to do Screen mirroring is a specification of iOS devices.
    
  • If using an Android
    Refer to the list of Wi-Fi Certified Miracast devices found on the Wi-Fi Alliance website for more details.

    Screen Mirroring playback may not be displayed, due to compatibility limitations with the Windows video driver.
