TCL 85A400M-UK 85 Inch A400M 4K Ultra HD HDR QD-Mini LED Smart Google TV 2026

The TCL 85A400M-UK is built for home cinema enthusiasts who want a truly massive screen without compromising on picture quality. This 85-inch TV solves the problems of blooming and poor black levels in standard large-screen LED TVs by using up to 448 precise dimming zones and high HDR brightness, delivering deep blacks and bright highlights that rival much more expensive TVs. With 93% DCI-P3 colour gamut, All-Domain Halo Control that eliminates halo effects, ONKYO 2.0 Hi-Fi audio and Google TV with Gemini AI, you get exceptional performance on a truly grand scale.

Ultra-Slim Unibody Design
The A400M features an integrated flat-back design that looks slimmer from the side and more immersive from the front, with a clean wall presence that elevates any living space. At just 41.9mm thin on the 85" model, it feels less like a device and more like part of your home.

QD-Mini LED with Up to 448 Precise Dimming Zones
QD-Mini LED combines the wide colour performance of QLED with the precise light control of Mini LED, bringing backlight control closer to pixel-level accuracy. The 85A400M delivers up to 448 dimming zones for deeper blacks and higher brightness.

Dark scenes look genuinely black without blooming, and bright highlights pop with clarity on the massive 85-inch screen. You get OLED-like contrast with higher peak brightness and a longer lifespan.

High HDR Brightness
Even in a bright room, you can still enjoy clear pictures with vivid colours and see more detail in both sunny and shadowy scenes. The A400M delivers strong HDR brightness for stunning, lifelike images.

93% DCI-P3 Ultra-Wide Colour Gamut
Using Quantum Dot technology, the A400M unveils over 1 billion hues of vibrant, precise colours, providing up to 93% colour gamut according to the DCI-P3 standard.

Your favourite films and shows look more lifelike with deeper reds, truer blues and more natural greens across the massive 85-inch display.

Bionic Colour Optimisation Technology
This technology intelligently analyses image content and enhances scene colours with remarkable precision while restoring and protecting natural skin tones.

Scenes look more vivid and immersive, but faces stay natural and believable even on an 85-inch screen.

All-Domain Halo Control Technology
All-Domain Halo Control covers the entire path from light generation to imaging, integrating high-efficiency chips, self-developed lens technology, Micro-OD, light-and-shadow algorithms and TCL CSOT HVA panel technology.

Halos around bright objects on dark backgrounds are virtually eliminated. On an 85-inch screen, this is absolutely essential for maintaining picture quality.

Powerful Light-Emitting Chip
Compared with previous generation conventional chips, the A400M's powerful light-emitting chip significantly improves brightness and energy efficiency, with a 53.8% brightness increase and 10% energy efficiency improvement.

You get better picture quality while using less energy, saving you money on electricity bills despite the massive screen size.

Condensed Micro Lens
TCL's self-developed condensed micro lens technology precisely controls light direction, greatly improving backlight uniformity and halo control capabilities with an 8 times increase in optical stability.

Picture details are clearer, with improved halo control and consistent backlight performance across the entire 85-inch screen.

Micro-OD for Better Image Quality, Thinner Body
With TCL's powerful Mini LED optical technology, Micro-OD offers a slimmer TV unit while significantly reducing the Mini LED halo issue.

Stars in the night sky look deep, delicate and sharp, and the 85-inch TV looks elegant on your wall.

HVA Panel Technology with 5000:1 Native Contrast
HVA panel technology enhances contrast by improving light control through the liquid crystal layer, making dark areas darker and the picture more immersive, with a native contrast ratio of 5000:1 compared to just 1200:1 for conventional IPS panels.

Dark areas appear even darker, significantly enhancing the screen's contrast ratio and delivering a more vivid, immersive visual experience.

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 means less heat build-up and long-lasting reliability, so you can watch for hours without worrying about performance.

ONKYO 2.0 Hi-Fi System with Wide Sound Field
With decades of home theatre expertise, ONKYO tuning delivers balanced, engaging sound for movies, sports and gaming. Side-firing speakers widen the sound field by 35% and improve audio-visual alignment.

Dialogue stays clear and sound effects are immersive. On an 85-inch screen, the audio needs to fill the room, and ONKYO delivers.

Tutti Choral – Cinema-Level Experience
The TV works seamlessly with compatible TCL soundbars for synchronised, more immersive surround sound.

Add a TCL soundbar for the ultimate audio experience, with synchronised sound that moves with the picture.

144Hz Native Refresh Rate with 288Hz Game Accelerator
The A400M leverages VRR technology to deliver dual-mode ultra-high refresh rates: native 4K at 144Hz and 1080P at 288Hz, plus AMD FreeSync Premium Pro, ALLM and HDMI 2.1.

Gaming on an 85-inch screen is incredibly smooth with less stuttering, tearing or blurring. Gamebar provides customised settings for all three major consoles.

TSR AiPQ Processor
The TSR AiPQ processor delivers pixel-level optimisation with AI ClarityMaster, AI ContrastMaster, AI ColourMaster and AI MotionMaster.

Every frame bursts with vibrant dynamism, layered depth and natural clarity. Lower resolution content looks cleaner with reduced noise.
