TCL 55A400 Pro ART QD- Mini Led NXTVISION TV (2026)

Frame-inspired form

Ultra-slim profile for a frame-like look

The 39.9 mm ultra-slim profile helps the TV sit closer to the wall, creating a cleaner, picture-like look that blends naturally into your space.

One-piece bezel

Light walnut woodgrain finish

An integrated one-piece bezel means no extra frame kits to buy or install.

The warm woodgrain look complements a wide range of interiors, from modern to classic.

Seamless wall mounting

Flush to the wall, like a framed artwork

With its ultra-slim one-piece design, there’s no external box to hide and no complex in-wall work required—it mounts as effortlessly as a regular TV, yet looks like a piece of modern wall art.

Halo thermal design

Helps dissipate heat even when mounted flush to the wall

Designed to help dissipate heat even with a close-to-wall setup.

High-thermal-conductivity materials and an optimized airflow path help move heat away from key components to support stable performance over time.

With two height settings, you can fine-tune the viewing height and leave room for a soundbar or décor.

QD-Mini LED display technology

Flagship picture quality, from art to gaming

TCL's QD-Mini LED is a flagship display technology that combines Mini LED backlighting with Quantum Dot color.

This powerful duo delivers higher contrast, greater brightness, and richer, more accurate colors for everything you watch.

Precise Dimming Series — up to 448 zones

Deeper blacks, higher brightness

Precise Dimming is TCL's advanced Mini LED backlight system that divides the screen into independently controlled zones*.

With refined halo control, a matte HVA panel, and TCL's light-and-shadow algorithm, it reduces blooming and reveals deeper blacks, brighter highlights, and more detail than conventional TVs.

QLED

Vivid visuals, lifelike colors

A400 Pro's QLED display uses nanoscale quantum dots to deliver a wider color palette and purer, more accurate hues.

Colors stay bright yet natural, so artwork, photos, and movies look rich and lifelike.

Matte screen

Glare-free viewing, art-like finish

The matte HVA panel uses a nanocrystal anti-glare coating to soften reflections and create a canvas-like finish.

Art and photos stay clear and vibrant, even in bright rooms.

Ambient light sensor

Automatically adjusts brightness to match your room

The ambient light sensor detects the lighting in your environment and automatically fine-tunes the screen brightness.

Whether in a bright room or a dim space, artworks and images look more natural and true to life.

TSR AiPQ Processor

AI picture engine for lifelike viewing

The TSR AiPQ Processor is an AI picture engine that analyzes every scene in real time, optimizing contrast, color, clarity, and motion so everything on A400 Pro looks more vivid, layered and lifelike.

144 Hz refresh rate

Next-generation smoothness for every scene

A true 144 Hz panel delivers smoother motion and clearer detail in fast-moving scenes — perfect for action films and next-gen gaming.

TV Mode

From artful display to smooth, cinematic viewing

A400 Pro switches seamlessly from Art Display to a full-featured smart TV experience.

With QD-Mini LED and the TSR AiPQ Processor, everything from movies to games looks smooth, vivid, and lifelike.

ONKYO 2.0 Hi-Fi System

Great sound to match stunning picture

Side-firing ONKYO speakers deliver a wide, immersive soundstage for movies, music and art.

Even on the wall, voices stay clear and details stay clear, so the sound lives up to the picture.

Three ways to fit your space

Wall-mounted, on a cabinet or on a stand

A400 Pro supports three placement options—wall-mounted, on a tabletop stand, or on a floor stand*—so it blends into any room.

Choose the setup that suits your home and style, and enjoy a beautiful viewing experience wherever you place it.

Mobile floor stand

Art that moves around your home

With the optional mobile floor stand, A400 Pro becomes a big-screen TV you can move from room to room.

Simply roll it to your ideal spot and angle it for comfortable viewing anywhere at home.

Move between rooms

Style every corner of your home

Whether you’re watching a movie in the living room, catching up on a series in the bedroom, or enjoying a bright indoor corner, you can easily roll A400 Pro to where you want it.
