The TCL 55S451 is a 55-inch 4K LED smart TV from TCL's entry-level 4-Series, running the Roku TV smart platform. It covers the basics well: 4K resolution, HDR playback, and Roku's simple interface with a large app selection and a built-in tuner. It suits budget buyers and secondary rooms more than movie buffs. Against rivals like the Hisense A4/A6 series and Amazon's Fire TV Omni, it gives up brightness, contrast and gaming features, but Roku's interface is widely considered easier to live with than most budget smart systems.
