The A400 Pro 4K QLED Google TV combines artistic design with top-tier QD-Mini LED picture quality. This television delivers bright and high-contrast images along with vivid colors, making both movie watching and displaying art images enjoyable. Its ultra-thin profile and wooden frame complete a stylish, picture-like appearance that blends naturally into your interior.

Art and Design

The design of the A400 Pro is inspired by a picture frame, and its 39.9 mm thin body allows for installation flush against the wall. The integrated wood veneer frame finish creates a warm and natural look that suits a variety of interior styles. The TV also serves as an art gallery, featuring about 80 high-resolution artworks at no extra cost. Additionally, you can upload your own photos and create stunning displays.

Picture Quality and Technology

TCL’s QD-Mini LED technology combines Mini LED backlighting with Quantum Dot color technology, ensuring high contrast, brightness, and color accuracy. Up to 448 independently controlled dimming zones reduce light bleed and enhance black depth. The matte surface reduces reflections, keeping the picture clear even in bright rooms. A 144 Hz refresh rate guarantees smooth motion, especially in fast scenes and gaming.

Sound and Operating System

The ONKYO 2.0 speaker system offers a wide and clear soundstage supporting Dolby Atmos audio. The Google TV operating system makes smart features easily accessible, including popular streaming services like Netflix, Disney+, and Yle Areena. HDMI 2.1 ports and AMD FreeSync support also make the TV compatible with gaming consoles.

Versatile Placement

The A400 Pro can be wall-mounted, placed on a table with an adjustable stand, or used with an optional mobile floor stand. This allows you to position the TV exactly where you want and adapt it to different spaces in your home.
