The TCL A400U 98" 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.
