• 🍎 AirPlay - only on TVs Apple TV 4K, Samsung (2018+ models), LG (With webOS 4.0+) and some Sony (with firmware) Android TV 9+).
• 🖥️ DLNA/UPnP — supported by almost all Smart TVs, but only allows you to stream media files (not the entire screen).

2. Connect via Miracast (for Windows and Android)

Miracast — the most universal protocol for wireless screen sharing. It is built into Windows 8.1/10/11 and the majority Android-devices. The main condition: both the laptop and the TV must be connected to the same Wi-Fi network (or use Wi-Fi Direct).
