TCL 55C6K 55-Inch 4K UHD QD-Mini LED Google Smart TV (Black)
The TCL 55C6K is a 55-inch 4K Ultra HD QD-Mini LED Smart TV from TCL’s C6K Series. Engineered with Quantum Dot Mini LED backlight technology, it merges the wide color volume of Quantum Dots with local dimming control to deliver high contrast, deep black levels, and bright highlights. Constructed on a High-Contrast HVA panel with All-Domain Halo Control technology, it suppresses backlight blooming and preserves contrast even in illuminated rooms.
Driven by TCL’s AiPQ Pro Processor, the 55C6K supports a native 144Hz refresh rate with Variable Refresh Rate (VRR) capabilities extending up to 288Hz VRR (and 240Hz DLG) for fluid gaming performance. It offers full dynamic HDR decoding—including Dolby Vision IQ, HDR10+, and HLG—complemented by an integrated 40W ONKYO 2.1-Channel Hi-Fi Audio System featuring an internal rear subwoofer, Dolby Atmos, and DTS Virtual:X. Operating on the Google TV platform, it provides hands-free voice control, tailored app recommendations, and advanced gaming optimizations.

Common FAQs
What is the benefit of the ONKYO 2.1 speaker system on the TCL 55C6K?
Unlike standard flat-panel TVs that rely on basic down-firing 2.0 stereo speakers, the 55C6K includes a dedicated 20W ONKYO subwoofer built directly into the rear cabinet. This produces deeper bass and balanced low-frequency performance for movies and games without requiring a separate floor subwoofer.
How does QD-Mini LED technology differ from standard LED or basic QLED TVs?
Standard QLED TVs use a global edge-lit or direct-lit LED backlight behind a Quantum Dot filter layer. QD-Mini LED uses thousands of microscopic LED chips that allow for precise local dimming zone control. This enables deep black levels and higher peak brightness while virtually eliminating backlight haloing.
What high-frame-rate features are supported for next-gen gaming consoles and PCs?
The 55C6K features HDMI 2.1 bandwidth supporting native 4K@144Hz input, Auto Low Latency Mode (ALLM), AMD FreeSync Premium, and Variable Refresh Rates up to 288Hz VRR (or 240Hz at 1080p via DLG).
Does this model support hands-free Google Assistant?
Yes, built-in far-field microphones allow you to control power, search for movies, launch apps, and manage smart home devices using hands-free voice commands (“Hey Google”) without using the remote control.
