TCL 55A400 Pro 55" QD-Mini LED 4K 144Hz Art TV

Since this is part of TCL’s Art TV series, design takes center stage. The screen sits inside a light walnut-textured frame with no visible seams, thanks to a single-piece bending process. It stays incredibly slim at just 3.99 cm for up to 75 inches and 4.45 cm for the 98-inch version. 

The rear panel takes on a textured finish inspired by vintage hardbound books. TCL supports three placements: a slim wall bracket for a flush mount, a two-stage desktop stand, and an optional mobile floor mount with wheels.

On the performance side, the A400 Pro uses TCL’s QD-Mini LED tech with independent zone dimming and Quantum Dot Pro materials that cover 157% of the BT.709 gamut. It supports native 4K at 144Hz, plus 288Hz output in Game Mode. There’s also VRR, ALLM, and AMD FreeSync Premium Pro baked in.

TCL backs the visuals with the TSR AI engine, which tunes color, clarity, and motion frame by frame. The screen also adjusts brightness automatically using an ambient light sensor. 

In Art Mode, the TV doubles as a digital canvas. It includes over 100 curated artworks and can generate original pieces using AI. It runs on Lingkong OS 3.0, skips boot ads, and uses the Fuxi AI model to power 18+ smart assistants for gaming, fitness, education, and more.
