Wirelessly broadcast your smartphone screen to a big-screen TV Mystery opens up new possibilities: from watching movies in high definition to showing presentations or gaming without an HDMI cable. However, many users face difficulties setting up such a connection. Unlike brands like Samsung or LG, televisions Mystery often use their own protocol implementations Wi-Fi Direct, Miracast or DLNA, which requires specific actions.
In this article we will look at all current connection methods (including hidden settings), we'll explain why sound might not work or lag might occur, and provide a checklist for diagnosing problems. We'll pay special attention to the nuances of compatibility with iPhone and older models Android (up to version 10). If your TV Mystery Released after 2020, most methods will work out of the box, but devices from 2018–2019 will require additional manipulation.

- 🔄 Firmware update: go to
Settings → Support → Software UpdateOutdated software often blocks Wi-Fi Direct. - 📶 Network mode: TV and phone must be connected to one Wi-Fi network (for DLNA) or be within Wi-Fi Direct coverage area.
On smartphone:
- 📱 Android/iOS version: For Miracast You need Android 4.2+ or iOS 11+ (but on iPhone it only works via AirPlay, which Mystery does not support it - more on that below).
