So it seems not to be an actualy HDMI reciever that just outputs your devices screen on the TV so that you can do anything with it like playing back moviews, playing games on the big screen etc ? Thats that, i had hoped it was basically a Miracast reciever..HTC has a similar device called the Media Link HD which does this, its $90 though but seems to be the way to go for me as i dont want to be limitied by whats possible in chrome.
