Overview

The TCL 43S517 is a 43-inch 4K Ultra HD Smart LED TV that punches above its weight class by including Dolby Vision HDR — a feature typically reserved for higher-priced models. Dolby Vision dynamically adjusts brightness, contrast, and color on a scene-by-scene and even frame-by-frame basis, resulting in a more lifelike and immersive viewing experience across supported content on Netflix, Disney+, Apple TV+, and other streaming services. The 4K resolution (3840x2160) provides sharp, detailed images that make the most of the 43-inch panel, whether you are watching nature documentaries, sports, or playing console games.

The Roku TV platform is one of the TCL 43S517's strongest features, offering a clean, responsive interface that organizes all your inputs and streaming services in one place. With access to the Roku Channel Store's vast library of free and paid apps, there is no need for an external streaming stick. Connectivity includes three HDMI 2.0 ports (one with ARC), a USB 2.0 port, optical digital audio output, Ethernet, and integrated Wi-Fi. The dedicated game mode is a welcome addition for console gamers, reducing input lag to keep gameplay feeling responsive. At 18.5 lbs without the stand, the TV is light enough for easy wall mounting, and its dimensions make it a practical fit for bedrooms, offices, or smaller living spaces.
