EISA Awards: Award-Winning Product

Each year, dozens of European journalists gather to select the best electronic products of the year. Awarded by a diverse and impartial jury, the EISA (Expert Imaging and Sound Association) awards recognize exceptional products for their performance, design, or ergonomics.

Overview

The TCL 85C9K features QD-Mini LED technology with precision backlighting; this 85-inch model combines 5,184 local dimming zones, a peak brightness of 6,500 nits, and full HDMI 2.1 gaming technologies. With its 90W Bang & Olufsen audio system and Google TV platform, it targets demanding movie lovers and gamers seeking exceptional picture quality in a refined design.

QD-Mini LED Precise Dimming Series Technology

With the C9K, TCL introduces its “Precise Dimming” series, marking a major evolution in Mini LED technology. This new generation incorporates high-performance electroluminescent chips, ultra-condensed microlenses, and Micro-OD technology to perfect the light shape of each zone.

The 5,184-zone backlighting system on the 85-inch model offers precise control over every section of the screen. This exceptional density, combined with dynamic control algorithms, enables halo control several times superior to ordinary zones. The “all-domain halo control” technology covers the entire process from light generation to imaging.

The CSOT HVA panel with Crystglow coating delivers a higher native contrast ratio. This 10-bit VA panel ensures faithful reproduction of nuances with dynamic contrast rated as “Mega” in the technical specifications.

Professional-Level Picture Performance

The 6,500-nit peak brightness places the C9K among the brightest TVs in its segment. This outstanding brightness enables striking HDR rendering even in very bright environments, revealing details in highlights without compromising black depth.

Quantum Dot Pro technology uses colored nanocrystals that combine nanometric quantum dot materials with multilayer organic materials. This approach displays over a billion shades of vivid color with exceptional accuracy and chromatic richness.

The AiPQ Pro processor analyzes and optimizes every image in real time. This artificial intelligence automatically adjusts brightness, contrast, and saturation according to viewing conditions. UHD Deep Learning AI SR upscaling enhances lower-resolution content to near-Ultra HD quality.

Extended HDR compatibility includes Dolby Vision IQ with dynamic adaptation to ambient lighting, HDR10+ for scene-by-scene optimization, standard HDR10, and HLG for broadcasting. The image performance index of 5,200 attests to the panel’s responsiveness and precision.

High-Performance Gaming with HDMI 2.1

The C9K features four HDMI 2.1 ports offering advanced gaming capabilities. VRR (Variable Refresh Rate) and FreeSync Premium Pro compatibility eliminate screen tearing, while ALLM (Auto Low Latency Mode) automatically optimizes latency when a console is detected.

The native 144Hz refresh rate ensures perfect smoothness for fast content and video games. The automatic game mode instantly adjusts settings to optimize responsiveness without manual intervention.

HDMI port 1 supports eARC for uncompressed audio transmission to a soundbar or home theater amplifier. This setup allows for a true multichannel audio system while retaining all gaming features.

Premium Bang & Olufsen Audio

The 90W audio system, developed in partnership with Bang & Olufsen, features a sophisticated configuration with an integrated woofer. Dolby Atmos and DTS Virtual-X Virtualization & Upmix compatibility create a three-dimensional soundstage without additional speakers.

The 7-band equalizer allows precise adjustment according to room acoustics and personal preferences. Bang & Olufsen’s beosonic system ensures a premium audio signature with deep bass and defined midrange.

Automatic sound control prevents abrupt volume changes between sources and commercials. Dolby TrueHD support ensures audiophile-grade playback of Ultra HD Blu-ray content.

Advanced Google TV Smart TV

Google TV replaces the former Android TV with the more intuitive ATV 12.0 interface and 63 available languages. The Quad Core processor ensures smooth navigation through menus and apps. The 52.7 GB internal memory (50.7 GB usable) provides ample space for apps and data.

The built-in smart microphone enables voice control via Google Assistant. Access to the Google Play Store opens the door to thousands of apps, including Netflix, YouTube, Amazon Prime, and Apple TV+ in 4K.

HbbTV 2.0.3 compatibility ensures access to European connected TV services. Chromecast and T-cast functions make streaming from mobile devices easy.

Comprehensive Connectivity and Reception

Integrated Wi-Fi ax/ac/n 2.4/5GHz MIMO ensures stable and fast connections. Bluetooth A2DP HID allows connection of audio and control devices. The RJ-45 port offers a wired alternative for critical network connections.

The triple tuner DVB-T2/C/S2 with CI+ 1.4 ECP support guarantees reception of all European terrestrial, cable, and satellite signals. Diseq v.1.0 and Unicable ver. I & II support facilitate complex satellite installations.

The two USB ports (1x 2.0 + 1x 3.0) allow media playback and connection of HID devices. The optical audio output maintains compatibility with existing audio systems.

Premium Design and Build

The “edge-to-edge” screen with brushed aluminum finish brings a modern aesthetic that blends with contemporary furniture. The central stand offers optimal stability while minimizing the footprint on the TV stand.

Despite its large dimensions (188.8 x 112.4 x 37.9 cm with stand), the TV maintains an elegant design. The weight of 36.4 kg requires careful installation but remains manageable for an 85-inch model.

The VESA 600x400mm mount allows for standard wall installation. Without the stand, the thickness of just 58mm makes for discreet wall integration.

What the press says

The TCL C9K is an excellent TV overall. Its exceptional brightness makes it an ideal choice for a bright living room, as it easily eliminates daytime glare. It looks just as stunning in the dark thanks to its highly effective Mini LED local dimming. Colors are vivid and punchy, but there are a few notable color accuracy issues to note before calibration. It’s an excellent gaming TV thanks to its many features, such as VRR support, low input lag, and support for very high refresh rates.

Le TCL C9K est un excellent téléviseur dans l'ensemble. Sa luminosité exceptionnelle en fait un choix idéal pour un salon lumineux, car il élimine facilement les reflets en plein jour. Il est tout aussi magnifique dans l'obscurité grâce à sa fonction très efficace de gradation locale Mini LED. Les couleurs sont vives et éclatantes, mais quelques défauts notables de précision des couleurs sont à noter avant l'étalonnage. C'est un excellent téléviseur gaming grâce à ses nombreuses fonctionnalités, comme la prise en charge du VRR, un faible input lag et la prise en charge de fréquences de rafraîchissement très élevées.
