The TCL A400U is a 75-inch 4K smart TV using QD Mini LED backlighting, which pairs quantum-dot color with many small LEDs for strong brightness and contrast. Its 144Hz panel suits sports and console gaming better than the 60Hz sets common at this size. It runs TCL's Google TV platform with voice control built in. It is a step below TCL's flagship QM-series Mini LED models, so it gives up some peak brightness and dimming zones, but it covers the basics well for a large living-room TV.
