How to know when content is casting

The Cast button will automatically appear in your Chrome toolbar and turn blue  Inactive cast extension when it’s active. You'll also see a glow around the icon of the tab being cast.

What can be cast

You can cast the majority of web content. Sites using plug-ins like Silverlight, Quicktime & VLC aren’t supported and may result in a lack of picture or sound.

Audio and video

You’ll see video and images for the selected tab on your computer and TV. However, you’ll only hear sound from the selected tab on your TV. Note: Sounds for other tabs and applications will continue to play on your computer.

If my Chromecast is currently in use

After opening the menu or selecting the device, you’ll see a short description of Chromecast’s current activity. Click the Cast this Tab button to stop what’s showing and cast the current tab instead.

Shortcuts available
