Google is diving face first into its Chromecast / Google cast ecosystem. And now casting is baked into the latest builds of Chrome. The easiest way to do this is to right-click anywhere in Google Chrome or click the hamburger icon in the top-right and select 'Cast'. If you click the top-left side of this new pop-up menu, you can choose to cast that individual tab or cast your entire desktop. You will also have the ability to choose which device you wish to cast to, either a Google Cast-enabled TV or a Chromecast.
