All I can say about chromecast is, it is an Amazing product to own. It is like a small dongle which can be connected to your TV . So that the TV becomes a natural extension of your tablet, phone or laptop.
I can stream live content from my laptop to mobile on my TV. I can view movies, videos, music etc. sitting on my sofa controlling all aspects such as video, audio selection, playback, volume etc.while enjoying high definition comfortable viewing. It is easy to install and easy to use.
So as they say just Plug and play straight from the web onto your TV screen.!
