However, not all users know how to properly configure the connection, especially if the device models were released in different years or operate on different protocols.
In this article, we will look at three main connection methods: through the built-in function Smart View (previously - Screen Mirroring), standard protocol Miracast and technology Wi-Fi DirectYou'll also learn how to troubleshoot common issues like no signal, frozen images, or sound problems. If your TV isn't Samsung, and, for example, LG or Sony Bravia, some of the instructions will still remain relevant - the operating principles of wireless technologies are universal.
Before you begin, check two key points:
1) Both devices are connected to the same Wi-Fi network (for some methods this is required).
2) The TV is in signal reception mode (usually called Screen Mirroring, Wi-Fi Direct or Miracast).
