Ultra-slim unibody design
A clean wall presence that elevates any living space
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.

Flush-fit wall look
Less protrusion, cleaner lines
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.

Up to 448 Precise Dimming Zones
Deeper blacks, brighter highlights
Precise Dimming Series refers to Mini LED TVs with all-domain halo control. A new generation of high-efficiency light-emitting chips, condensed micro-lens optics, and Micro-OD architecture helps shape each zone more accurately and reduce halo. Combined with a high native-contrast HVA panel and advanced light-and-shadow algorithms, it delivers more cinematic contrast and clearer details than conventional TVs.
