Your Chromecast allows you to mirror your entire desktop directly onto your TV at any time.

This feature is now integrated into Google Chrome, so unlike the early days of Chromecast, you no longer need the Google Cast extension for this. However, you still need to use Google Chrome. You cannot use any other browser such as Mozilla Firefox or Microsoft Edge.

Cast a Chrome tab to your TV

You can use a Chromecast device to display a chrome tab or your screen on your TV.

You can display most web content. Some plug-ins, such as Silverlight, QuickTime and VLC, do not work.

To display chrome on your TV, you need a Chromecast device:

  • A Chromecast, Chromecast Ultra or a TV with built-in Chromecast.
  • A computer and a Wi-Fi network with the minimum system requirements.
  • A current version of Google Chrome (version 72 or later).
  • Update your Google Chrome browser if necessary.
  • To connect your computer and Chromecast device to the same Wi-Fi network. Learn how to check the Wi-Fi network on your Chromecast device.
