A clean wall presence that elevates any living space
Ultra-slim unibody design
A400M features an integrated flat-back design that looks slimmer from the side and more immersive from the front—so it feels less like a device and more like part of your home.
As slim as 39.9mm on selected sizes* | Flat unibody back | Minimal bezel
* Thickness varies by size: 55"/65"/75" — 39.9 mm; 85" — 41.9 mm; 98" — 44.5 mm.
* Content is for reference only. The actual product (including but not limited to appearance, color, and size) and on-screen images may differ slightly.

Less protrusion, cleaner lines
Flush-fit wall look
Designed for a cleaner wall presence, A400M reduces visual bulk and helps your space look more refined and modern.
Less protrusion | Cleaner lines | Fits modern interiors
* For the slimmest wall fit, an ultra-slim wall mount is required (may be sold separately). Actual gap may vary depending on installation and wall conditions.

Cooling designed for long viewing sessions
Star ring cooling system
The star ring cooling system helps reduce heat build-up in tight spaces, supporting stable performance for everyday, all-day viewing.
Efficient cooling | Less heat build-up | Built for long sessions
* Thermal performance may vary depending on installation conditions, ambient temperature, and usage.

Flexible placement
Designed to fit more spaces
Whether wall-mounted or placed on a stand, A400M keeps a clean, premium look that fits different rooms and layouts.
Wall or stand* | Fits more spaces
* Stand design and installation options may vary by size and region.


Mini LED TV: The Halo Eliminator
TCL All-Domain Halo Control Technology
TCL all-domain halo control covers the full path from light generation to final imaging. By integrating high-efficiency chips, self-developed lens technology, Micro-OD, light-and-shadow algorithms, and TCL CSOT HVA panel technology, it helps reduce halo and deliver a cleaner, more premium viewing experience.
Powerful light-emitting chip | Condensed micro lens | Micro-OD | Dynamic lighting bionic algorithm
Transient response | Bidirectional 23-bit | HVA panel technology

Powerful light-emitting chip
High-efficiency chips improve brightness and energy efficiency, reproducing natural bright and dark scenes with greater clarity.
53.8% brightness increase | 10% energy efficiency increase
*Data from TCL laboratories. Results may vary by test conditions and standards.

Condensed Micro Lens
TCL's condensed micro-lens design precisely directs light to improve backlight uniformity and halo control, making details clearer.
Improved halo control | Enhanced uniformity | 8x optical stability
*Data from TCL laboratories. Results may vary by test conditions and standards.

Micro-OD
Micro-OD helps keep the TV slimmer while supporting cleaner light control, reducing halo and sharpening delicate highlights—like stars against a night sky.
*Images are for illustrative purposes only. Refer to the actual product.

Dynamic lighting bionic algorithm
Optimizes lighting for SDR and HDR based on human perception and pixel information, improving contrast and detail across scenes.

Transient response
Faster light response works with the control algorithm to reduce trailing and improve clarity in fast-moving content.

Bidirectional 23 bit
The more precise the backlight control, the clearer the image details
Bidirectional 23 bit precision control technology can accurately sense the ambient brightness and color temperature, and finely control the TV brightness and color temperature to make the picture more vivid and colorful.
*The relevant data comes from TCL laboratories, and different testenvironments or standards may lead to inconsistent test results.
HVA panel technology
HVA panel technology enhances contrast by improving light control through the liquid crystal layer, making dark areas darker and the picture more immersive.
*The native contrast ratio varies by size, see specifications for details.
*The relevant data comes from TCL laboratories, and different test environments or standards may lead to inconsistent test results

Bright and brilliant
High HDR Brightness
Even in a bright room, you can still enjoy clear pictures with vivid colors and see more detail in both sunny and shadowy scenes.
High HDR Brightness | Conventional HDR
* Brightness performance may vary by size, region, and picture mode.


QLED
More than a billion hues of vivid color
TCL QLED uses advanced quantum dot materials and a high-transmittance film to improve light efficiency and color stability. Together with backlight technology, each frame renders rich, vivid color with smoother gradients—revealing subtle details for a more immersive, lifelike viewing experience.
High-transmittance filter | Colorful quantum crystal | Up to 93% DCI-P3 wide color gamut
Enhanced stability | Bionic color optimization
* Data from TCL laboratories. Results may vary by test conditions and standards.

Colorful quantum crystal
Next-generation quantum crystals use multi-layer nano protection and precision crafting for more stable, long-lasting color.
High light efficiency | Composite nano structure | Multi-layer co-extrusion precision | 4000+ hours of extreme testing


TSR AiPQ Processor
Powered by TSR AiPQ Processor Computational image quality
The TSR AiPQ processor integrates TCL’s proprietary tuning algorithms and intelligent perception to optimize clarity, contrast, color, and motion at the pixel level—so every frame looks more natural, layered, and lifelike.

Gaming
288Hz Game Accelerator
A400M leverages VRR to deliver dual-mode refresh rates: native 4K at 144Hz and 1080p at 288Hz. Run, race, and shoot with less stutter, tearing, and blur for a faster, smoother experience.
*288Hz requires supported mode and compatible device/content.

Perfectly balanced light and shadow
Perceive the brightness information of each image in the TV picture, and combine the brightness characteristics of the viewing environment to intelligently adjust the contrast of the picture to make the bright and dark details clearer.
True color inspired by the creator
Intelligently identify the color characteristics of the picture, and carry out dynamic color calibration and skin tone protection, bringing more vivid color performance, allowing users to get an immersive experience when playing games or viewing movies.
Crystal clear vision than ever
Powerful Ai data models accurately parse each frame of images, and perform pixel-level optimization on flawed images, so that even low-score images can present high-resolution image quality effects.
Actional scenes and smooth details
Powered by TCL AiPQ Pro Processor, MEMC detects fast-moving objects sensitively in their size and position in the image, it calculates motion in terms of frame number with up to 4K 144Hz VRR, just to restore the silky-smooth image in compensating for blurring and tearing in the exciting sports, games, and movies.
Full range of HDR
The Powerful TCL Ai HDR supports almost all HDR formats such as Dolby Vision, HDR 10+, HDR10, HLG, etc. And plus, it could upscale SDR to HDR by enhancing the picture quality in movies and shows with a wider range of colors with brighter highlights.
