TCL has made a name for itself by offering feature-rich TVs at competitive prices, and with the release of the C7K series in 2025, it continues that tradition. This mid-range QLED Mini-LED TV succeeds the TCL C765/QM751G and positions itself as a strong alternative to models like the Hisense U7NQ—offering better contrast, impressive gaming features, and advanced display tech.
Whether you’re a gamer, movie enthusiast, or casual viewer, the TCL 65C7K provides a well-rounded experience at a reasonable price.
Design & Build
The TCL 65C7K (also known as Q7C or QM7K) sports a clean, modern design dominated by a nearly frameless front and a subtle 1 cm bezel, housing the panel’s tech components. While the chassis is primarily plastic, it doesn’t feel cheap. The stand is centrally mounted and fixed in height, ensuring stability without needing a wide surface.
The TCL 65C7K (aka Q7C and QM7K) has a nice overall design, even though it’s mostly made of plastic.
All connectivity ports—except the power input—are conveniently located on the right side, making them easy to access even with a wall mount (VESA 300×300 compatible). There’s also thoughtful cable management with rear clips.
At its thickest point (5.6 cm), the TV is still wall-friendly. Though there’s a slight flex on the plastic back, the overall build quality is solid for its category. The remote control includes quick-launch buttons for major streaming platforms, a built-in mic for voice commands, and—bonus—backlit keys for dark-room viewing.

Display Quality
The C7K’s picture quality punches well above its price point, thanks to a CrystGlow HVA panel and full-array Mini-LED backlighting.
-
HDR brightness peaks at over 1,700 nits (10% window), making it a great choice for HDR content.
-
SDR peak brightness hits around 600 nits, which is more than sufficient for everyday viewing.
-
Native contrast exceeds 7000:1, and blacks remain deep and inky even with local dimming off.
-
With 2048 dimming zones (double that of the QM7K), the C7K offers impressively precise backlight control.
That said, some haloing can be seen around subtitles or small bright highlights in dark scenes, but it’s not overly distracting.
Color volume is excellent, especially in SDR. HDR color accuracy out of the box is less precise, but calibration improves it significantly. Gamma tends to run bright by default, but again, this can be fine-tuned.
Upscaling and image processing are solid, delivering clean visuals even from lower-quality sources.
Naturally, HDR movies and TV shows look great on the C7K thanks to the display’s high brightness.
Motion Performance & Gaming Features
The C7K is a top performer in its class when it comes to gaming. With two HDMI 2.1 ports supporting 4K at 144Hz and 1080p at up to 288Hz, this TV caters to high-performance console and PC gamers alike.
-
VRR (Variable Refresh Rate) support includes HDMI Forum VRR, AMD FreeSync, and NVIDIA G-Sync.
-
Input lag is impressively low—just 10ms at 1080p60 in Game Master mode.
-
Response time clocks in at 6ms, fast enough for smooth motion without excessive blur.
-
Black Frame Insertion (BFI) and interpolation options further refine motion clarity.
Some overshoot occurs during transitions from dark to light, resulting in slight inverse ghosting, but it’s a minor tradeoff considering the smoothness overall.
Smart Features
Running Google TV (version 12), the C7K provides a user-friendly smart experience with all the bells and whistles:
-
Hands-free voice control via Google Assistant
-
Support for Apple AirPlay 2, Google Chromecast, Amazon Alexa, and Apple HomeKit
-
A comprehensive app library with personalized recommendations
The UI is clean and intuitive, offering quick access to live TV, streaming platforms, and content libraries. Ads are present, as with most smart TVs, and they can’t be turned off.
Sound Quality
Despite being equipped with Bang & Olufsen-designed woofers, the built-in sound is underwhelming. Bass is minimal, volume is limited, and the overall audio lacks impact.
On the bright side, dialogue remains clear and balanced. For a more cinematic experience, an external soundbar or speaker system is recommended. Pairing the C7K with a model like the TCL Q85H significantly improves immersion.
The C7K models have HDMI 2.1 throughput on HDMI 1 and 2, with both supporting up to 4K144. HDMI 4 has eARC but is limited to HDMI 2.0 throughput.
Connectivity
The TCL C7K offers a robust range of inputs:
-
HDMI 1 & 2: Full HDMI 2.1 with 4K144 and VRR
-
HDMI 4: HDMI 2.0 with eARC for high-quality audio pass-through
-
Two USB ports (including USB 3.0), Ethernet, optical audio, CI slot, and analog AV/headphone out
-
Wireless: Wi-Fi 5 and Bluetooth 5.4
This wide range of options makes it easy to connect modern and legacy devices alike.
Final Verdict: A Mid-Range Marvel
The TCL C7K series is a standout in the mid-range segment, offering top-tier contrast, rich HDR performance, and superb gaming features—without a premium price tag. While its viewing angles and built-in audio leave room for improvement, these are minor drawbacks given the display quality and versatility it delivers.
Whether you’re a gamer chasing high refresh rates, a movie lover who craves bright and colorful visuals, or someone looking for an all-purpose smart TV, the C7K is a compelling choice.
