This guide will explain how to stream your Android smartphone screen to a Smart TV, using both wireless and wired connection technologies. By the end of reading, you will be able to project apps and games onto the TV screen, making the most of your device's features.

This procedure is useful for those who want to use apps and games on a larger screen, enhancing the visual and entertainment experience. It is particularly suitable for those who own a latest-generation Smart TV and an Android smartphone.

Wireless transmission technologies

Android supports various wireless transmission technologies to send content to a compatible receiver. The main ones are Google Cast (Chromecast) and Miracast.

Google Cast (Chromecast)

• Google Cast, also known as Chromecast, is a technology developed by Google that allows sending content from Android smartphones and tablets, as well as computers with Google Chrome browser, to a compatible receiver. All involved devices must be connected to the same Wi-Fi network.
• Smart TVs with Google TV/Android TV operating system natively support Google Cast. Some televisions with different operating systems, such as LG Smart TVs with WebOS 25 or later versions, are labeled as Chromecast-ready or Google Cast-ready.
• If your TV is not compatible with Google Cast, you can purchase an HDMI device as a receiver, such as the Google TV Streamer or the Chromecast with Google TV.
• Once the receiver is configured, you can stream multimedia content from apps compatible with Google Cast or the entire Android screen.

Miracast

• Miracast is another wireless transmission technology supported by Android, based on Wi-Fi Direct. It allows direct communication between two or more devices without the need for a router.
• All smartphones with Android 4.2 or later versions can stream the screen in mirroring mode via Miracast.
• Many Smart TVs, even not the latest, support Miracast as a receiver. To activate the receiver, turn on the TV and open a dedicated app or a specific menu.
