TCL A400U 75-Inch Smart Google TV 4K HDR

The TCL A400U 75" Wallpaper QD-Mini LED TV combines a slim, wall-ready design with a bright, dynamic picture. It uses QD-Mini LED technology to control light precisely, delivering deeper blacks and brighter highlights while Quantum Dot colour provides richer, more natural shades. An AiPQ Pro Processor analyzes what you’re watching in real time to adjust colour, contrast and clarity for a balanced picture. The TV includes an ONKYO 2.0 Hi-Fi system for clearer dialogue and deeper bass, and supports Dolby Atmos and DTS Virtual:X for immersive sound. The HVA Pro Panel enhances contrast and sharpness while reducing reflections, and the display reaches up to 2500 nits with 836 dimming zones for visibility in daylight. Additional features include Dolby Vision IQ, Art Mode, a 144 Hz panel for smooth action, and Google TV with Google Assistant built in. Some apps and services may require firmware updates and may not be available in all regions.
