Overview
Plug the TCL 55S401 in, connect to Wi-Fi or Ethernet, and the Roku interface puts streaming channels, a cable box, a Blu-ray player and a game console behind one home screen. The panel is LED backlit and displays 4K UHD resolution, with HD sources upscaled toward near Ultra HD. Four HDMI inputs and a USB port handle wired gear, while built-in speakers with Dolby Digital Plus cover everyday audio.
Buyers who want one smart TV to run streaming apps and several wired sources without flipping through inputs will find the Roku platform does the switching for them. The panel favors convenience over picture ambition, so anyone chasing deep blacks or high frame rate gaming should look at what the set cannot do before deciding.
Who it's for
Households that watch streaming apps plus a cable box or console and want one simple interface for all of it. The set suits a wall or table setup thanks to the VESA pattern and included stand. Shoppers who need top tier HDR performance or a wide viewing angle should look elsewhere.

Performance notes
The Roku processor handles app switching and input changes, so how quickly menus respond depends on the network connection and the streaming service. LED backlighting sets the contrast ceiling, and HDR10 content gains brightness and color range over standard signals. Upscaling smooths lower resolution sources toward the panel's native resolution, while fast motion reveals the panel's refresh behavior.
