Overview

TCL's 55S455 is a 55-inch 4K UHD LED TV with Roku's smart platform built in, sized for a main living room screen. It runs at a 60Hz refresh rate and weighs about 22 pounds per the listed specs, light enough for most wall mounts.

At 55 inches with a 4K panel, detail should scale up well from typical living room viewing distances, and Roku's interface runs directly on the set rather than needing a separate box. The 60Hz refresh rate is standard for everyday viewing rather than tuned for gaming.
