The TCL 85A400M-UK is an 85-inch 4K Ultra HD HDR smart TV that runs Google TV with Gemini AI. It uses a QD-Mini LED backlight with up to 448 dimming zones. This gives deeper blacks and higher HDR brightness.
Quantum Dot technology provides over 1 billion hues and up to 93% of the DCI-P3 color gamut. Bionic Colour Optimisation analyzes image content and enhances scene colors while protecting natural skin tones. Audio is ONKYO 2.0 Hi-Fi.
All-Domain Halo Control reduces halos around bright objects on dark backgrounds. It combines high-efficiency chips, a self-developed condensed micro lens, Micro-OD, light-and-shadow algorithms and TCL CSOT HVA panel technology.
