If you have Netflix on your smartphone, perhaps you'd like to get the video from the phone to your TV. Luckily, there are devices that make that easy. Google Chromecast is a simple media player that connects to your TV and lets you wirelessly send anything that's on your phone to your television.
Chromecast calls this "casting," and you can use this to watch Netflix at full resolution on your TV. In a similar way, if you have an Apple TV, you can wirelessly connect your phone using Bluetooth and display video like Netflix on your television.
