This TCL 65-inch Class S4 is a 4K UHD smart TV with Roku TV built in. It shows 4K content at 4 times the resolution of Full HD. HD content is upscaled to near Ultra HD resolution. It supports HDR formats for enhanced contrast, color and detail.
The design has a metal finish, a slim profile and a FullView edge-to-edge glass front. The home screen is customizable and puts broadcast TV, streaming channels, game consoles and other devices up front. A live TV channel guide covers over-the-air channels from the built-in digital TV tuner and live streaming channels, including 250+ free channels. It also works with cable-replacement services such as Sling, Hulu and fuboTV.
The simple remote has about half the number of buttons of a traditional TV remote, with one-touch access to popular streaming channels. The free Roku mobile app for iOS and Android works as a second remote, with private listening and voice or keyboard search. The TV works with Siri, Alexa and Google Assistant, and supports Apple AirPlay. Software updates arrive automatically. Search finds movies, shows, songs and podcasts across thousands of channels and shows where they stream for free or at the lowest cost.
