TCL A400 Pro Art TV NXTVision: 144 Hz Mini LED at the heart

TCL continues its offensive on the designer TV segment with the presentation in China a few weeks ago of the new A400 Pro series comprising five models, the TCL 55A400 Pro (140 cm), TCL 65A400 Pro (165 cm), TCL 75A400 Pro (191 cm), TCL 216400 Pro (140 cm) and TCL 98A400 Pro (249 cm). This model succeeds the TCL A300 Pro series, launched in 2024 by the Chinese manufacturer (as a reminder, in France, the TCL A300 model without the Bang & Olufsen 3.1.2 sound system was also released). TCL A400 Pro: What are the main technical specifications? The TCL A400 Pro features a major upgrade with significantly more premium equipment that, according to AVcesar, should be a game-changer. The Edge LED backlighting system has been replaced with a Mini LED system (no further details were provided at the time of writing). This change results in the 2025 TCL A400 Pro being thicker than the 2024 TCL A300 Pro, measuring 39.9 mm compared to 27.9 mm. Most importantly, this major change will bring numerous improvements in image quality: optimized contrast, higher peak brightness, and more ambitious HDR management. As a reminder, HDR HLG, HDR0+, and Dolby Vision IQ compatibility are included. Also worth noting is a native 144Hz and 288Hz LCD panel in 1080p.

TCL A400 Pro: What Art TV features does it offer? On the Art TV side, there's an enhanced Art mode with dozens/hundreds of pre-installed artworks and a visual rendering much closer to a painting thanks to the new matte coating (reference AG25) and a decorative panel frame. With the generative AI features already present in the TCL A300 Pro TVs, the TCL A400 Pro screens also offer the ability to create themed images or animated paintings. Finally, a wheeled stand was presented in China (see photos above), but it is unknown whether it will be distributed in France. TCL A400 Pro: What are the sound and connectivity options? The 3.1.2 audio system, including an external subwoofer developed by Bang & Olufsen, is present on the TCL A300 Pro and replaced on the TCL A400 Pro by an integrated system from Onkyo. However, Dolby Atmos and DTS Virtual:X compatibility are still included. Finally, the TCL A400 Pro TVs still feature four HDMI 2.1 ports (actually one 4K/144 HFR, one 4K/120 HFR, and two 60Hz ports, powered by a Pentonic 700 chip) certified with eARC, VRR, and ALLM, not to mention support for FreeSync Premium Pro. More information will be available at CES 2026 in Las Vegas in early January.
