YES NOW you can, with the latest version of the Chromecast app. I really love Chromecast, and with screen mirroring, love it even more. One little annoying glitch is, that after you watch something, turn everything off, and come back the next time, there is no sounds. I have to unplug the device from the tv, also from the power to the device, wait a few seconds then reconnect all and it works fine. I also use it to show photos on my tablet to a group of people, right on the big screen. Very cool device, tiny price, and now that it screen casts, even better.
