Overview

The TCL 55S401 is a 55 inch 4K UHD television with an LED display and the Roku smart platform built in. It connects via Ethernet or Wi-Fi and weighs 30 pounds.

Built in Roku means streaming apps and channel navigation run through Roku's own interface rather than a separate streaming box, and the set can reach the network by Ethernet or Wi-Fi. A 55 inch 4K panel puts it in the mid size range for a living room television.
