To cast from Chrome, you must have the Google Cast Extension installed on your Chrome Browser. Learn how to install the Cast Extension here.
Some sites, such as YouTube and Netflix, are optimized for Cast, and deliver the best possible experience. We are working with more sites to enable them to optimize for Cast. For other sites, it is possible to cast a tab to get that content on your Chromecast.
On sites that are optimized for Cast, there are numerous benefits to using controls provided by the site instead of just casting the tab for that site. These include:
Higher quality: Cast-optimized sites can serve high quality content that is best for viewing on TV. This will often means 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: Cast-optimizes sites play directly on Chromecast, and put no load on your computer. Casting a tab requires a lot of your computers power, which is why it's not supported on all computers.
,
Plays independently: When you play from Cast-optimized sites, you can shut down your computer or close the lid. With tab projection, you need to keep your computer on throughout the cast.
Cast optimized sites will generally try to automatically switch from casting a tab to an optimized 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 optimized, but whenever you see the Cast icon in the video player of a site, that should be your first choice
Once you're set up to Use Chromecast with Chrome, casting a tab is just a click away! To start casting a tab of your Chrome Browser:
Make sure you are on the tab you want to project to your TV.
Press the Cast button in the Chrome toolbar (top right hand area) of your browser.
A list of available Chromecast devices will appear on your TV. Pick any device to cast the current tab to this device.
After a very brief load time, the current tab should appear on your TV!
You will see the Cast icon change color to indicate that it is active, and you'll see a glow around the icon for the tab that is being shown.
If your Chromecast is currently in use - for example, it might already be playing a YouTube video - when you open the menu or select the device, you will see a short description of what Chromecast is doing, possibly with some controls (pause, mute, etc) for that activity. Click the 'Cast this Tab' button if you wish to terminate the current activity, and cast the current tab instead. This helps to ensure that you don't accidentally pick the wrong device and interrupt another household member!
The significant majority of web content can be cast. However, sites that use plug-ins such as as Silverlight or Quicktime are not supported, and may result in a lack of picture or sound.
During tab casting, video and images for the tab being cast will be shown on your computer and on your TV. However, sound from the selected tab will only play on your TV. Sounds for other tabs and applications will continue to play on your computer. You may switch to other tabs and/or applications while casting; you can even do this in full-screen mode using the Alt-Tab (Mac: Command-Tab) keyboard shortcut.
While casting, you can click the Cast icon again to take any of the following actions:
Click on the status area that shows what is being cast to return to the tab that you started casting from.
Mute what's playing on your TV using the mute button. This is distinct from your TV's mute function, so you need to unmute from Chrome.
Click on the "Stop" button to stop casting.
You may also stop casting by closing the tab.
