SAMSUNG SERO TV

The biggest phone accessory ever. Samsung's latest gizmo, as seen at CES 2020, is the Sero, a TV the company says is "designed for the mobile generation." As in, it automatically flips from a standard wide-screen TV into a vertical portrait mode, just like your phone. Except the screen measures 43 inches diagonally instead of 6.1 inches.

Portrait mode is actually the default setting for this TV, but Sero's integrated motorized mount rotates the screen back and forth to taste, controlled by a button on the remote or via Samsung's SmartThings app. Own a Samsung Galaxy phone? You can sync it with the TV so the screen flips automatically when you rotate your phone -- although prepare to disable that feature after it inevitably activates by mistake for the ninth time.

As with many other TVs, you can mirror your phone's screen on the TV itself, but in vertical mode it will look a lot better (and bigger), in particular with vertical videos from YouTube, Facebook or your own camera roll. And yes, you can mirror other phones too, including iPhones. The TV features all of Samsung's smart TV extras, including Apple's AirPlay 2 system for features such as screen mirroring and video streaming.
