The TCL A400U is a QD-Mini LED 4K Google TV in TCL's Designer Series, sold in 55- and 65-inch sizes. It combines quantum-dot color with mini-LED backlighting, a 120 Hz panel and an anti-glare coating, and it runs Google TV with Google Assistant and AirPlay-style casting to Siri devices. It sits above TCL's basic QLED sets but below its flagship mini-LED models, so it trades some peak brightness and dimming zones for a slimmer, design-led build. It suits buyers who want strong contrast and wide color for movies and sports without stepping up to the top tier.

Owners generally rate the A400U well for picture contrast, color and value against pricier mini-LED sets. Complaints center on brightness in very bright rooms and on sound quality from the thin chassis.
