An anonymous reader writes from an Engadget article: Vizio's latest P-Series 4K HDTVs are more than just an annual upgrade -- they also completely redefine how you'll be accessing media. The TVs, which range from 50- to 75-inches, are still technically 'smart,' but they don't have any apps of their own. Instead, you'll have to stream content with built-in Google Cast -- a first for any TV set. You can shoot media to the sets using the Vizio SmartCast app, either from the included Android tablet remote, or any other iOS or Android device. SmartCast also serves as the central hub for discovering media, and it controls all of your TV settings. The 6-inch Android tablet that comes with every P-Series set isn't very exciting on its own: It's got a 1080p screen and a V8 octa-core processor. But it's significantly more interesting than the traditional remotes most TVs ship with. As for that SmartCast app, it's surprisingly well designed. You can search for TV shows and movies, and it'll point you right to it on the appropriate streaming service.
