Display & Design
The TCL 50S450R boasts a lively 4K UHD resolution that provides four times the detail of regular 1080p TVs. With its HDR PRO capability that comes with Dolby Vision, HDR10, and HLG, the colors look more precise, highlights are brighter, and shadow detail is enhanced for a natural viewing experience.
The Direct LED backlighting provides enhanced brightness evenness across the screen in comparison to edge-lit screens, while Motion Rate 120 minimizes blur when watching high-speed content such as sports and action movies.
Its FullView metal bezel-less style provides the TV with a modern and streamlined look that easily integrates into any room. The 50-inch screen size is optimal for medium-sized rooms, providing cinematic experience without dominating the space.
