  Anynet+ may not work on your Samsung Monitor due to several reasons. First, ensure the device is an Anynet+ compatible device, as the system only supports these.

Also, verify that Anynet+ (HDMI-CEC) is set to 'On' in the System menu and that the remote control is Anynet+ compatible. Anynet+ may not function during initial setup.

  If the message “Disconnecting Anynet+ device ...” appears on your Samsung Monitor, it means you cannot use the remote control while Anynet+ is configuring or switching to a view mode.
