Some Vizio TV models come with a built-in Chromecast, which means you don't need a Google Chromecast device in order to cast Crunchyroll on your Vizio smart TV. To check whether your Vizio TV has a built-in Chromecast, you need to see if your Vizio TV has Wifi or internet connection options available. Being able to enable Wifi means your Vizio TV supports all the smart functions, including SmartCast and Chromecast.
