TCL A400 Pro: when design becomes a œuvre d'art and the picture a spectacle
The TCL A400 Pro reinvents the TV by combining aesthetics inspired by the finest picture frames with next-generation display performance. Its ultra-slim profile, its elegant one-piece frame with light walnut wood effect finish and its matte screen allow it to blend harmoniously into any interior while turning into a true decorative object when not in use. Behind this refined design lies state-of-the-art QD-Mini LED technology, capable of delivering deep contrast, rich colors and remarkable brightness. Equipped with an ONKYO-branded Hi-Fi audio system, an integrated collection of œuvres d'art and numerous installation options, the TCL A400 Pro offers an immersive experience for movies, video games and showcasing your most beautiful memories.
Spectacular picture quality thanks to QD-Mini LED technology
The TCL A400 Pro features QD-Mini LED display technology, which combines Mini LED backlighting with Quantum Dot technology to deliver an image of exceptional precision. Independent local dimming zones, reaching up to 448 zones depending on the model, significantly improve contrast while enhancing black depth and the intensity of highlights. Combined with TCL exclusive light and shadow management algorithms and the matte HVA panel, this technology ensures a detailed and immersive viewing experience for movies, video games or displaying œuvres d'art.
A TV designed to enhance your interior
Much more than just a screen, the TCL A400 Pro blends naturally into your decor thanks to its picture-frame-inspired design. Its matte screen effectively reduces reflections thanks to a nanocrystal-based anti-glare coating, delivering a result close to a real canvas even in brightly lit rooms. The Moments feature also makes it easy to import photos from your smartphone to create a personalized gallery, photo walls or decorative ambiances that showcase your memories every day.
A premium experience down to the smallest details
The TCL A400 Pro adapts to any space thanks to several installation options: ultra-discreet wall mounting, installation on furniture, or use with an optional mobile stand. The latter makes it easy to move the TV from one room to another thanks to its swivel casters with braking system. On the audio side, the ONKYO Hi-Fi system complements the visual performance by delivering powerful, immersive sound, so you can fully enjoy movies, concerts, series or video games in the best possible conditions.
