I am unsure what Chromecast is doing so far but think there may be a useful usage in my work. Most of our conference room have installed 46" FHD TVs. Can I use plug Chromecast in the HDMI port of TV and send my powerpoint to the TV from my iPad or Windows 8 tablet wirelessly. In addition, I can use the iPad or Windows tablet to control the presentation. Can someone who has got this device to confirm it works.
