Miracast (Android)
You can easily wirelessly transmit the screen from an Android phone to your TV even without additional devices. Miracast is the standard established by the Wi-Fi Alliance to wirelessly connect smartphones, tablets and notebooks with displays, such as televisions and monitors, to stream audio and video content. In order for the connection to be successful, both devices must be Miracast certified: in this way, communication will be made using the Wi-Fi Direct standard, which allows direct connection even in the absence of a home Internet network or an access point. The transmission resolution supports both Full HD and Ultra HD 4K with 5.1 surround sound. The data flow is encrypted with the WPA2 security standard.
To verify that your phone is Miracast certified, visit the Wi-Fi Alliance page. Google has in fact natively supported the standard operating systems Android 4.2 (KitKat) and Android 5 (Lollipop), abandoning it with Android 6 (Marshmallow) and later. Support for Android operating systems therefore depends on the specific models of manufacturers and their customization of operating systems. In case your phone does not support it, there are alternative solutions that we will see later.
Regarding the TVs, in this case you need a Smart TV. Check the data sheet carefully to verify that it supports Miracast natively, otherwise it will be necessary to use a device that makes it compatible. Desktop computers and notebooks running Windows 8.1 or Windows 10 can both send and receive media streaming.

The screen transmission of an Android phone with Miracast is simple: go to the Settings menu, select Screen and then Transmit. The icon of the latter command is sometimes available in the menu dedicated to notifications and quick commands of the main screen of the smartphone. The name of the receiving device, such as the TV, will appear and simply click it.
