Yes, you can watch movies on television, provided your device is connected to the Internet. Many smart TVs have the Viewster app preinstalled. If the Viewster app is not already installed on your TV, you can find it in the app store. Then you can log in and select a movie to watch.
If, for any reason, no Viewster app is available on your device, you can hook up your PC or Mac to your TV and use it as a monitor or cast the content onto TV screen using the Chromecast app.
