The TCL A400 Pro Series 55-inch (139 cm) is a 4K Ultra HD QD-Mini LED Smart Google TV designed to combine high-performance home entertainment with wall-art aesthetics. Featuring an ultra-slim frame-inspired profile with an integrated woodgrain bezel and a nanocrystal anti-glare matte HVA panel, this television functions as a digital canvas displaying curated art collections or personal moments when not in use, transitioning seamlessly into a vibrant entertainment display.

Powered by the TSR AiPQ Processor, the television utilizes artificial intelligence to analyze scenes in real time, optimizing contrast, clarity, color, and motion. Its Mini LED backlighting system is organized across 112 independent local dimming zones, pairing with Quantum Dot color technology and 93% DCI-P3 color gamut coverage to produce deeper blacks, minimize blooming, and deliver vivid visual reproduction under triple HDR formats including Dolby Vision, HDR10+, and HLG.

Built for modern media streaming, console gaming, and spatial audio integration, the Google TV platform provides centralized access to streaming applications with hands-free Google Assistant voice control. Gamers benefit from a true 144 Hz native refresh rate panel equipped with Game Master and AMD FreeSync support, while side-firing ONKYO 2.0 Hi-Fi speakers with Dolby Atmos and DTS:X processing provide clear sound staging without requiring an immediate external soundbar.
