TCL 75S451 75-Inch 4-Series 4K UHD Roku Smart TV

The TCL 75S451 brings 75 inches of 4K UHD resolution into your living room, combining sharp detail with HDR10 and HLG support to enhance contrast and color accuracy across compatible content. Powered by the Roku smart TV platform, it puts thousands of streaming channels, free live TV, and a customizable home screen at your fingertips — eliminating the need for a separate streaming device. Voice control compatibility with Siri, Alexa, and Google Assistant means you can search for shows, adjust settings, and launch apps without reaching for the remote, while AirPlay support makes it easy to share content directly from Apple devices.

Connectivity is well covered with four HDMI inputs — including one eARC port for high-quality audio passthrough to a soundbar or receiver — along with dual-band WiFi, an Ethernet port, USB 2.0, and a digital optical audio output. The FullView edge-to-edge glass design keeps the aesthetic clean and modern, while practical features like the private listening mode through the Roku mobile app, automatic software updates, and an easy-to-use remote with channel shortcut buttons add everyday convenience. For cord-cutters, the built-in digital TV tuner with a Live TV Channel Guide provides access to free over-the-air broadcasts, rounding out a comprehensive entertainment package on a single screen.
