Latest update to Chromecast app allows screen mirroring | Android and Me. Finally, an update to the Chromecast software has arrived that allows screen mirroring. So, if you want to demonstrate your phone's features in a presentation to a group, you will be able to fire up this beta feature, and wirelessly connect to any TV with a Chromecast attached. I have done this in the past with a Verizon Wireless dongle, and there is some third party software out there that will do it. But, it is nice to have the feature available. So, if you want the FutureLawyer to demonstrate mobile phone technology at your next gathering, just ask. Or, if you are a trial lawyer who wants to send video to in court TV screens, you can do it without wires.
