TCL A400U 85-inch 4K Ultra HD QD-Mini LED Smart TV

The TCL A400U is a premium 85-inch 4K Ultra HD Smart TV designed to deliver a cinematic home entertainment experience. Utilizing advanced QD-Mini LED display technology, this television combines the vibrant color accuracy of QLED with the precise contrast control of Mini LED backlighting. With a native 4K resolution of 3840 x 2160 pixels, a peak brightness of 2500 cd/m², and a 6500:1 contrast ratio, it ensures that every scene is rendered with exceptional clarity, deep blacks, and brilliant highlights.

Advantages

This television stands out due to its sophisticated 1008-zone precise dimming system, which effectively eliminates halos and enhances shadow detail. The integration of the HVA Pro Panel technology provides an ultra-high native contrast ratio, ensuring that dark scenes remain rich and detailed. Gamers will benefit from the 288Hz VRR Game Accelerator, which minimizes motion blur and tearing for a fluid, competitive experience. Furthermore, the ultra-slim 41.9mm design allows the TV to sit nearly flush against the wall, acting as a piece of digital art when not in use through its dedicated ambient and gallery modes. The inclusion of the ONKYO 2.0 Hi-Fi system ensures that the audio quality matches the high-end visual performance, providing a balanced and immersive soundstage.
