Big-screen QD-Mini LED performance

Its 4K Ultra HD resolution makes it a natural choice for large living rooms, films, sport and next-generation gaming.

This 75-inch version uses 240 precise local dimming zones, allowing different areas of the Mini LED backlight to be controlled independently.

Bright highlights can remain vivid while darker areas appear deeper and more detailed, helping to reduce the halo or blooming sometimes visible around bright objects on dark backgrounds.

Up to 700-nit HDR brightness

With peak HDR brightness of up to 700 nits, the 75A400M produces impactful highlights and retains detail in brighter scenes.

The high-contrast HVA panel works alongside TCL’s all-domain halo control technology to improve black levels, shadow detail and overall picture depth.

Support for Dolby Vision IQ, HDR10+, HDR10 and HLG allows the television to work with a wide range of HDR films, programmes, streaming services and games. Dolby Vision IQ can also adjust the picture to suit the lighting conditions in your room.

Rich QLED colour

TCL’s Quantum Dot technology reproduces more than one billion colour shades and covers up to 93% of the DCI-P3 colour space. This gives films, sport and nature programmes richer colour, smoother gradients and more natural-looking skin tones.

The TSR AiPQ Processor analyses each scene and optimises clarity, contrast, colour and motion. Lower-resolution television and streaming content is intelligently processed to appear cleaner and more detailed on the large 75-inch 4K screen.

144Hz gaming with 288Hz Game Accelerator

The native 144Hz panel keeps fast movement smoother and clearer, making the TCL 75A400M well suited to console and PC gaming. Compatible devices can take advantage of 4K gaming at up to 144Hz, while the 288Hz Game Accelerator provides an even faster refresh rate at 1080p resolution.

HDMI 2.1, Variable Refresh Rate, Auto Low Latency Mode and AMD FreeSync Premium Pro help reduce screen tearing, stutter and input delay. TCL Game Master also provides a dedicated Game Bar, aiming assistance and quick access to relevant gaming settings.

Google TV with smart recommendations

Google TV brings streaming services, live television and connected devices together through one easy-to-use home screen. Recommendations are organised around what you watch, while individual profiles and a dedicated children’s profile help personalise the experience for each member of the household.

Built-in Chromecast and Apple AirPlay 2 make it easy to share compatible photos, music and video from a phone or tablet. Voice control and Google Gemini features are also supported where available, allowing you to search for entertainment, ask questions and control compatible smart-home devices.

Art Gallery and Ambient Mode

When you are not watching television, the 75A400M can display artwork, personal photographs, digital clocks or calming ambient scenes. TCL’s Art Gallery includes a selection of classic, contemporary and pre-generated AI artwork, helping the screen become part of the room rather than simply a blank black panel.

ONKYO sound with Dolby Atmos

The integrated ONKYO 2.0-channel audio system delivers 20 watts of sound, with side-firing speaker design helping to create a wider soundstage. Dolby Atmos, DTS:X and DTS Virtual:X processing add greater space and depth to films, television and games.

A compatible TCL soundbar can also work with the television’s Tutti Choral feature, allowing the TV speakers and soundbar to operate together for a broader, more immersive presentation.

Ultra-slim 39.9mm design

Despite its 75-inch screen, the TCL A400M measures just 39.9mm deep across its flat-back cabinet. The minimal bezel and unibody design provide a clean appearance from the front and side, particularly when paired with a suitable slim wall mount.

TCL’s star-ring cooling system helps manage heat during longer viewing sessions, while the supplied stand provides an alternative for placement on a suitably wide television unit.
