How to Screencast Media with Your Android Phone
When you desire to watch movies, look at your photos, or listen to music from your Android phone on a large-format screen, it’s time to screencast: This technology takes the image presented on your phone (or music playing) and casts it to an HDTV or monitor.
To successfully cast media, the HDTV or monitor must have a screencasting gizmo installed, such as Google’s Chromecast. After you set up that gizmo, the screencast works like this:
Open the app that plays the media you want to watch or listen to.
Compatible apps include Play Music, Play Movies & TV, YouTube, Netflix, and similar apps.
Ensure that the HDTV or monitor is set to the proper HDMI input.
For example, if a Chromecast dongle is installed on HDMI Input 4, switch the TV to that input. The casting dongle must be awake and active.
Tap the Chromecast icon.
The icon appears. If you don’t see this icon, the media cannot be cast to another device or the casting gizmo isn’t on (refer to Step 2).
Choose a screencasting device from the list.
The phone begins to send the media to the other device.
You can still use your phone while it’s casting. The app may offer you controls, such as Play and Pause, or it might display additional information about the media.
To end a screencasting session, tap the Chromecast icon again and tap the Disconnect button.
