The TCL A400U 55" Wallpaper QD-Mini LED TV pairs a razor-thin design with a bright, bold picture. QD-Mini LED technology precisely controls light across the screen, giving you deeper blacks and brighter highlights with less glow around objects. Combined with Quantum Dot colour, you get richer, more natural shades. The AiPQ Pro Processor analyses what you're watching in real time, adjusting the colour, contrast and clarity for a more balanced picture. The ONKYO 2.0 Hi-Fi system uses 20 W of audio power for clearer dialogue and deeper bass, so everything feels fuller and more engaging.Good to knowThe HVA Pro Panel boosts contrast and sharpness while reducing reflectionsUp to 2500 nits of brightness and 448 dimming zones for a clear picture, even in daylightThe ONKYO 2.0 Hi-Fi system uses 20 W of audio power for clearer dialogue and deeper bassDolby Atmos and DTS Virtual:X spread audio around the room with added height and depthThe flat-thin design is just 39.9 mm deep, making it ideal for wall mountingDolby Vision IQ adapts to your room lighting for improved contrast and clarityArt Mode lets you display artwork, photos or calming scenesThe 144 Hz display keeps action smooth and clearGoogle TV smart platformGoogle Assistant built-inPlease note: Some apps & services (including tuner) are only available in the UK.
