TCL C655 / C69B 98' vs TCL C7K / QM7K 55"-85"

The quality of the HDR effect on TCL C655 / C69B looks quite promising. The average value in test patterns is about 450 nits, which already allows you to feel the brilliance of light effects and better image dynamics. However, as previously mentioned, this effect can be somewhat muted by slight differences in bright and dark colors, resulting from the lack of local dimming technology. However, the coverage of the DCI-P3 color palette at 94% deserves high praise, and this is possible due to the use of a quantum dot (QLED) matrix. As a result, colors are vibrant and well-reproduced when watching HDR content.

In terms of brightness, the models from 55 to 85 inches in the C7K series are truly impressive. In the best testing conditions, the 65-inch screen achieved over 1200 nits, which practically means that the brightest scenes can dazzle with almost cinematic brilliance. These are not just dry numbers from measurements – during screenings, white skies, explosions, or light reflections on water looked incredibly striking, often giving the impression that the television exceeds its price class. This is particularly effective in scenes with a large area of illumination, where the screen is filled with intense brightness – such as in sun-drenched shots or during dynamic action sequences. Viewers looking for strong HDR will definitely be satisfied.

However, scenes requiring precise control of backlighting – with small points of light on a dark background – are more challenging. Here the C7K, despite having over a thousand zones, can still dim brightness to maintain deep blacks. The effect is that in films like Sicario 2 or Life of Pi, some details, such as a distant lantern or single reflections, can be less defined or blend in with the surroundings. This is a compromise inherent to MiniLED technology – it provides excellent image depth and blacks at a level that ordinary LCDs do not offer, but this comes at the cost of limited visibility of the smallest lights.

The TCL C655 / C69B TV offers a movie mode that has been tested for color reproduction quality. Although this mode is called movie mode, it unfortunately has quite a few flaws that a director would certainly not want to see when recording their work. Starting with image analysis, it's worth looking at the white balance – both in HD and 4K HDR content, the white balance has significant errors. In both cases, the red color dominates, which makes the colors too warm, and the overall image takes on a pink or yellow tint. The Colour Checker test confirms these errors – the color samples shift to the wrong shades, affecting overall color fidelity. A lesser issue is the brightness characteristics. However, it is also not without flaws. The gamma chart shows a strong spike at the beginning, which can make the image excessively bright, and the EOTF curve responsible for brightness in 4K HDR content also has significant fluctuations – it is evident that the TV tries to maintain appropriate brightness, but it does not always succeed effectively.

The novelty in TCL televisions for 2025 is the long-awaited Filmmaker mode, which until now could be found in most competitive brands. This is great news because this mode is considered the most faithful to the original vision of the creators and is often recommended by enthusiasts of good picture quality. Unfortunately – as is often the case – the mere presence of this mode does not guarantee perfection. The Filmmaker mode in the TCL C7K is not free from flaws. One could point out the incorrect white balance, particularly the slight dominance of blue, which led to cool, somewhat grayish skin tones. But that was not the biggest problem. The main complaint was excessive brightness exposure, which is clearly visible in the gamma and EOTF charts. The image was simply too bright, at times almost blown out, which affected not only the depth of scenes but also the overall viewing experience. Some details were simply lost, and the whole image looked as if someone had slightly overdone the brightness slider. As always – we decided to see what could be squeezed out of this after calibration. And that’s when things started to get really interesting…

After calibrating the movie mode of the television TCL C655 / C69B , the white balance has been adjusted, and the colors appear as they should – which is confirmed by only slight deviations in the Colour Checker test. The gamma is really good, which means the television shouldn’t have issues with brightness in low-resolution materials. Unfortunately, a similar EOTF characteristic is still noticeable, which is a natural phenomenon in televisions that do not have local dimming – they simply struggle to "shine" brighter in a given part of the screen. Despite this design limitation that cannot be bypassed, we recommend adjustments in the settings because the overall color presentation is really very good.

After calibration, the TCL C7K showed itself in a really good light, especially when it comes to SDR content. We managed to tune the white balance, color gamut, and brightness characteristics so precisely that color errors on the ColorChecker palette dropped below a value of 2. For the uninitiated – this is almost a perfect result, which means that the image is very close to what the creators intended. Unfortunately, it looked worse with 4K HDR content. Although we were able to slightly calm the white balance and correct its previous errors, it is still evident that the television has some "MiniLED traits," especially in brightness management. When we checked how the C7K handles the EOTF curve on actual film scenes, and not just on synthetic test patterns, it turned out that the screen still tends to slightly brighten the entire image. This affects the overall experience – black loses some depth, and the image becomes less contrastive than it should be. Despite these minor shortcomings in HDR content, the overall reception of materials – especially in SDR – is really very good. After calibration, the C7K can display an image that can successfully compete with much more expensive models. Good color tuning, natural skin tones, and pleasant brightness make movie sessions and everyday content viewing more than satisfactory.

The TCL C655 / C69B TV handles tonal transitions well in lower-quality content. The "Gradual Smoothing" feature at its lowest setting effectively eliminates visible banding, but it also results in a loss of detail, such as in the texture of objects. A plus is that it does not interfere with film grain, allowing the image to maintain a natural look.

In terms of digital processing, the TV adds a considerable amount of artificial sharpness, which may appeal to those who prefer a vivid image. For those who prefer a more subtle representation of details, this could be a drawback. Another downside is the rather aggressive overscan – the image is cropped, which leads to the loss of parts at the edges and limits the field of view.

TCL C7K features a function that, according to the manufacturer, is supposed to smooth out unwanted color transitions – something like a rescue for less successful tonal changes. It's called "Gradual Smoothing" and... well, it sounds ambitious, but in practice, it works very poorly. Regardless of whether we set it to low or high, the difference is minimal. Worse still – the function can cut out elements from the image that should remain. Fortunately, film grain remains untouched, so at least it doesn't smooth everything indiscriminately, but still – it's better to just turn this option off.

When it comes to scaling lower-resolution content, it's already better. SD and HD materials look quite decent, although sometimes we felt that the image loses sharpness and becomes too soft – as if something took away its clarity. Fortunately, with very low sources (e.g., 576p), there was no overscan effect, meaning the image was not artificially cropped – everything fit on the screen as it should.

Unlike the smaller versions, the 98” model stands out with significantly better motion fluidity. Instead of the standard 60 Hz, this colossal screen is equipped with a full-fledged 144 Hz matrix, which opens up completely new possibilities – both for gamers and movie enthusiasts. With full motion smoothing, the TV provides incredible image fluidity, eliminating motion blur and improving the viewing comfort of dynamic scenes. It is worth emphasizing that this technology operates across the full refresh rate range, meaning there is no need to compromise between fluidity and quality. Additionally, the "Flicker Reduction" feature allows you to adjust the fluidity to your own preferences – you can opt for a more cinematic effect with visible frame drops or a maximally smooth image.

The TCL C7K handles motion fluency really well. The panel used in it offers a refresh rate of 144 Hz, which in itself suggests that this TV is something more than just an ordinary "60 Hz" panel. Moreover, if we connect the C7K to a computer and set the resolution to Full HD. But we'll write more about that in the paragraph about gamers and PC collaboration. Back to everyday use – both sports and movies look very good here. Thanks to the fast panel and well-functioning motion smoother, the C7K is great for watching matches, but also for movie screenings. In the menu, we find two sliders – blur reduction and flicker reduction – which allow you to tailor the smoothness effect to your own preferences. At lower settings, we get a more cinematic effect, with a slight stutter in motion. At higher settings – the image becomes more theatrical, smooth to the point of exaggeration. Everyone can set it up according to their liking.

The 98-inch TCL C655 / C69B is excellently equipped for gamers. Full-fledged HDMI 2.1 ports and a 144 Hz panel allow you to enjoy games in 4K resolution at 120 Hz, providing smoothness and responsiveness that will impress even the most demanding.

The TV supports Variable Refresh Rate (VRR), which eliminates screen tearing, and the Automatic Low Latency Mode (ALLM) ensures that games start instantly, without the need to manually switch settings. There’s also support for Dolby Vision and HGiG, making the image quality in games even better - details are sharp, colors natural, and contrast perfectly balanced.

Additionally, the TV offers a dedicated gaming panel that allows for quick adjustment of image settings without having to leave the game. It’s a device that meets practically all the requirements of the modern gamer.

TCL C7K is a television that on paper looks like the dream equipment for gamers – and most importantly, it holds up well in practice. First, the good news: we have two full-bandwidth HDMI 2.1 ports, so we can easily connect both a console and a computer, taking full advantage of their capabilities. The panel itself supports a refresh rate of 144 Hz, which provides a significant advantage in dynamic games. Additionally, it comes with a full suite of gaming features: VRR (variable refresh rate), ALLM (automatic low latency mode), and support for Dolby Vision in games. There's also an HGiG mode that allows for HDR effects consistent with the creators' intentions. GameBar, which is an informative bar for the gamer. It operates quickly, looks clear (like the Nintendo console👌), and shows what’s most important: the current frame count, VRR status, and even HDR parameters.
