Duplicating the screen on TV
Methods to display the contents of your mobile screen on TV vary by manufacturer of your mobile phone, the Android version and if your TV is smart or not.
Chromecast and other sticks HDMI
HDMI sticks are an extremely easy way to return your smart TV, even when it is not. They connect to the HDMI input on the TV and on your phone you can send content to be replayed on TV.
CC is the most popular, but it is not alone. In any case, the process is always similar. In an application that supports Google Cast (over 2000 and up), will appear automatically the button to send content. When pressed, select the device from the dropdown menu and ready.
