Google’s smart-TV dongle and the Chromecast is a very versatile gadget that can be used to stream video content from the Internet through a wide variety of devices and sites to a big screen TV. It works just a little bit better if you’re living within Google’s ecosystem, just like Apple’s devices work better together.
How to Cast Videos From iPhone or iPad to Chromecast
Make sure that your iOS device and Chromecast are connected to the same Wi-Fi network.
Open an app such as Netflix or Youtube, which supports Chromecast.
Load the video you want to cast.
Tap the Cast button, a square with three curved lines like the Wi-Fi symbol coming out of the corner.
If you only have a single Chromecast on the network, the video should start playing immediately. If not, you’ll see a list of available devices, and you’ll have to tap on the one you want to cast the video too.
