One of the sexier announcements at Google I/O 2014 today was for Chromecast display mirroring. This will allow Android phones and tablets to push their live view out to the TV wirelessly; that means apps don't need to specifically add Chromecast support anymore, and you can have an easier time seeing just about anything. This can even mirror your camera.
Chromecast mirroring will be included as a beta for select devices as Google Play Services get updated over the next couple of weeks. Those devices include those listed above: HTC One M7, LG G2, LG G2 Pro, Nexus 4, Nexus 5, Nexus 7 (2013), Nexus 10, Samsung Galaxy Note3, Samsung Galaxy S4, and Samsung Galaxy S5 to start.
Great news overall for Chromecast owners, and should enable all sorts of new uses. How would you like to do with Chromecast mirroring?
