Our take on the TCL A400U Designer Series QD-Mini LED QLED 4K Smart Google TV 55-inch

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.

Questions and answers

Is the A400U worth it over TCL's cheaper QLED TVs?
Yes if you want mini-LED contrast and 120 Hz. The step up buys deeper blacks and smoother motion than basic QLED sets.
How does it compare with TCL's flagship mini-LED models?
It has fewer dimming zones and lower peak brightness. The flagship sets are brighter and more precise, but the A400U covers the core mini-LED benefits.
Does it support 120 Hz gaming?
Yes, the panel is 120 Hz and there are four HDMI ports. Check that your console or PC supports the matching HDMI features.
What sizes does it come in?
It is offered in 55- and 65-inch versions. The 65-inch model is about 57 inches wide and weighs around 58 lb.
Does it work with Google Assistant and Siri?
Google Assistant is built into Google TV. Siri support comes through casting from Apple devices rather than a native Siri assistant.
Is the anti-glare coating useful?
Yes in bright rooms. It reduces reflections, though it does not match the brightness of premium mini-LED sets in direct sunlight.
