The less advantageous side of these protocols is that, since what they do is duplicate the screen from one extreme to the other, if one wants to send a series to the television, the mobile must always remain on.

Miracast is a wireless communication standard promoted by the Wi-Fi Alliance and compatible with the vast majority of portable devices. transmission in 1080p is very stablewith a latency low enough to take advantage of a video game.
