Google Cast Ready vs. Casting a Tab

Some websites are 'Google Cast Ready' to deliver the best possible experience. Currently, YouTube, Netflix, Google Play Movies, Google Play Music and more are Google Cast Ready. You can tell if a website is Google Cast Ready if you see the Cast icon on the website itself. For sites that are not Google Cast Ready, use the Cast Extension to view the website on your Chromecast.

On sites that are Google Cast Ready, there are numerous benefits to using controls provided by the site instead of just casting the tab for that site. These include:

  • Higher quality: Google Cast Ready sites can serve high quality content that is best for viewing on TV. This will often means that you'll get a full 1080p high definition picture; for some content you may also get 5.1 surround sound (if supported by your TV or receiver). When Casting a tab, you are limited to a maximum of 720p (if supported by your computer).
  • Battery life and computer load: Google Cast Ready sites play directly on Chromecast, and put no load on your computer. Casting a tab requires a lot of your computer's power, which is why it's not supported on all computers.
  • Plays independently: When you play from Google Cast Ready sites, you can shut down your computer or close the lid. With tab projection, you will need to keep your computer on throughout the cast.

Google Cast Ready sites will generally try to automatically switch from casting a tab to an optimised mode of operation if you are already casting a tab when you visit the site.

Casting a tab is still very useful for sites that aren't Google Cast Ready, but whenever you see the Cast icon in the video player of a site, that should be your first choice
