Overview

The TCL 43S451 43-Inch 4K UHD Smart Roku TV packs a lot of capability into a compact, affordable package. With 4K UHD resolution and HDR support, it delivers sharp detail and enhanced contrast that brings movies, shows, and games to life. The built-in Roku TV platform eliminates the need for external streaming devices, providing instant access to popular services and a clean, intuitive interface for browsing content. Dual-band WiFi and an Ethernet port give you flexibility in how you connect, and four HDMI inputs — including one with eARC — make it easy to hook up a soundbar, game console, Blu-ray player, and more without constantly swapping cables.

This renewed model retains the same FullView edge-to-edge glass design as the original, giving you a sleek, modern look with minimal bezels. Voice control compatibility with Siri, Alexa, and Google Assistant adds hands-free convenience for searching content and controlling playback. As a renewed unit, it has been professionally inspected and tested to meet manufacturer standards, making it a practical choice for anyone who wants reliable 4K performance in a bedroom, office, or smaller living space without paying full retail price.
