If you’d prefer to sign up for Peacocktv.com/tv on a mobile device or computer, or you don’t have an eligible television, Chromecast offers a workaround. Follow these steps to stream content from a Chromecast or Chromecast-enabled mobile device and smart TV.
Select content from the Peacock app or through the browser on your Chromecast-enabled device.
Select the Chromecast icon and choose your smart TV to begin streaming.
Tips: As long as your Chromecast-enabled device is a first-generation or more recent model, including TV models with built-in Chromecast or the Chromecast with Google TV should support streaming to a smart TV.
