How do I display or mirror from a Chromebook to a projector or TV?
Sometimes it can be helpful to "cast", (also known as "mirror"), your Chromebook or Mac's display onto a larger screen in order to share a lesson with your classroom. You can cast a tab or your desktop from the Chrome browser to a projector or TV using a connected Chromecast device.
Note: You can cast the majority of web content, however sites using plug-ins like Silverlight, Quicktime and VLC aren’t supported and may result in a lack of picture or sound.
