Hi there ~~PTVdisplay cast is a media streaming device that plugs into the HDMI port on your TV. Simply use your mobile device to cast your favorite TV shows, movies, music, sports, games, and more to the TV you already own. Chromecast works with your iPhone, iPad, Android device, MacBook, Windows laptopa. To many people, it is new and inexperienced.
