Overview

The TCL 50S425 is a 50-inch 4K UHD LED television built around the Roku smart TV platform, offering a streamlined entertainment experience that puts thousands of streaming channels at your fingertips. Its 3840 x 2160 resolution paired with HDR support produces a noticeably sharper and more vibrant image than 1080p sets, revealing fine details in nature documentaries, sports broadcasts, and cinematic content. The direct-lit LED panel provides even backlighting across the screen, and TCL's 4K Creative Pro upscaling engine helps lower-resolution content look its best on the UHD display.

Roku TV serves as the operating system, eliminating the need for a separate streaming stick or box. The interface is clean, fast, and regularly updated with new apps and features. Voice control through Amazon Alexa or Google Assistant lets you search for content, switch inputs, and adjust volume without picking up the remote. On the connectivity side, three HDMI 2.0 ports with HDCP 2.2, a USB media player port, composite AV inputs, optical audio output, and both dual-band Wi-Fi and Ethernet ensure compatibility with a wide range of devices and home network setups. The 200mm x 200mm VESA mount pattern and relatively slim 3.2-inch depth make wall installation straightforward.
