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

The quality of HDR effect on the TCL C655 / C69B looks quite promising. The average value in the test charts is around 450 nits, which already allows for a hint of the brilliance of light effects and better image dynamics. However, as previously mentioned, this effect can be somewhat subdued by slight differences in bright and dark colours, resulting from the lack of local dimming technology. Nevertheless, the DCI-P3 colour gamut coverage of 94% deserves high praise, and this is made possible by the use of a quantum dot (QLED) panel. As a result, colours are vibrant and well-rendered when watching HDR content.

In terms of brightness, the models ranging from 55 to 85 inches in the C7K series are truly impressive. Under the best testing conditions, the 65-inch screen reached over 1200 nits, which in practice means that the brightest scenes can shine with almost cinematic brilliance. These are not just dry numbers from measurements – during viewings, the white skies, explosions or reflections of light on water looked extraordinarily striking, often giving the impression that the television exceeded its price class. This is particularly effective in scenes with large areas of brightness, where the screen is filled with intense light – such as in sunlit shots or during dynamic action sequences. Viewers seeking strong HDR will definitely be satisfied.

However, scenes that require precise control of the backlighting – with small points of light on a dark background – prove to be more challenging. Here, the C7K, despite having over a thousand zones, still dims the brightness to maintain deep blacks. The effect is that in films like Sicario 2 or Life of Pi, some details, like a distant lantern or single reflections, can be less distinct or blend into the surroundings. This is a compromise inherent in 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 finest lights.

The TCL C655 / C69B television offers a film mode that has been tested for colour reproduction quality. Although this mode is called film mode, unfortunately, it has many errors that the director would certainly not want to see when recording their work. Starting with image analysis, it's worth examining the white balance – both in HD and 4K HDR content, the white balance has significant errors. In both cases, the red colour dominates, making the colours too warm, and the overall image takes on a pink or yellow tint. The Colour Checker test confirms these errors – the colour samples stray into incorrect shades, affecting the overall colour fidelity. A minor issue is the brightness characteristics. However, this too is not without flaws. The gamma graph shows a strong spike at the beginning, which can cause the image to be excessively brightened, and the EOTF curve responsible for brightness in 4K HDR materials also has significant variations – it is evident how the television tries to maintain the appropriate brightness, but it does not always manage to do so effectively.

A new feature in TCL televisions for 2025 is the long-awaited Filmmaker mode, which until now could be found in most competing brands. This is great news, as this mode is considered the one that most accurately represents 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 it does not guarantee perfection. The Filmmaker mode in the TCL C7K is not without its flaws. One can point out the incorrect white balance, particularly the slight dominance of blue, which resulted in cool, somewhat greyish skin tones. But that was not the biggest issue. The main complaint was excessive brightness exposure, which was clearly visible on gamma and EOTF charts. The image was simply too bright, at times even overexposed, which affected not only the texture of the scenes but also the overall viewing experience. Some details were simply lost, and the entire image looked like someone had slightly overdone the brightness slider. As always, we decided to see what could be squeezed out of it after calibration. And that’s where it started to get really interesting…

After calibrating the television's movie mode TCL C655 / C69B , the white balance has been adjusted, and the colours are displayed as they should be – which is confirmed only by slight deviations in the Colour Checker test. The gamma is really correct, which means the television shouldn't have problems with brightness in low-resolution materials. Unfortunately, a similar EOTF characteristic is still visible, which is a natural phenomenon in televisions that do not have local dimming – they simply struggle to "shine" stronger in a given section of the screen. Despite this design limitation, which cannot be bypassed, we recommend adjustment in the settings, as the overall coloration looks really very good.

After calibration, the TCL C7K presented itself in a really good light, especially when it comes to SDR content. We managed to precisely tune the white balance, colour gamut, and brightness characteristics so that the colour errors on the ColorChecker palette fell below a value of 2. For the uninitiated – this is nearly a perfect result, indicating that the image closely resembles what the creators intended. Unfortunately, it looked worse with 4K HDR content. While we slightly managed to calm the white balance and correct its previous errors, it still shows that the TV has some “MiniLED traits”, particularly in brightness management. When we checked how the C7K copes with the EOTF curve on real film scenes, rather than just synthetic test patterns, it turned out that the screen still tends to slightly brighten the entire image. This affects the overall impression – the black loses some depth, and the image becomes less contrasty than it should be. Despite these minor shortcomings in HDR content, the overall reception of materials – especially in SDR – is truly very good. After calibration, the C7K is capable of displaying an image that can successfully compete with much more expensive models. Good colour tuning, natural skin tones, and pleasant brightness ensure that movie sessions and everyday content viewing are more than satisfactory.

The TCL C655 / C69B television handles tonal transitions in lower quality materials well. The "Gradual Smoothing" function, at its lowest setting, effectively eliminates visible banding, but at the same time causes a loss of detail, for example, in the texture of objects. The advantage is that it does not interfere with film grain, allowing the image to maintain a natural appearance.

In terms of digital processing, the television adds a considerable amount of artificial sharpness, which may appeal to those who prefer a crisp image. For those who favour a more subtle representation of details, this could be a downside. Another drawback is the rather aggressive overscan – the image gets cropped, leading to the loss of portions at the edges and limiting the field of view.

The TCL C7K features a function that, according to the manufacturer, is designed to smooth out unwanted colour transitions – a sort of rescue for less successful tonal shifts. 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. What's worse, the function can cut out elements from the image that should remain. Fortunately, the film grain remains untouched, so at least it doesn't smooth everything indiscriminately, but still – it's better to simply turn this option off.

When it comes to scaling lower resolution content, it’s much better. SD and HD materials look quite decent, although at times we had the impression that the image was losing sharpness and becoming too soft – as if something was detracting from 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 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 entirely new possibilities – both for gamers and movie lovers. Thanks to the full motion smoother, the television provides incredible image fluidity, eliminating motion blur and enhancing the viewing comfort of dynamic scenes. It is worth noting that this technology works across the full refresh range, meaning that there is no need to compromise between fluidity and quality. Additionally, the "Flicker Reduction" function allows you to adjust the fluidity to your own preferences – you can opt for a more cinematic effect with visible frames or an extremely smooth image.

The TCL C7K handles motion smoothness really very well. The matrix used in it offers a refresh rate of 144 Hz, which in itself suggests that this television is something more than a regular "60 Hz" panel. What's more – if we connect the C7K to a computer and set the resolution to Full HD. But we will write more about this in the section for gamers and cooperation with PCs. Returning to everyday use – both sports and films look very good here. Thanks to the fast panel and well-functioning motion smoother, the C7K is great for watching matches, as well as for film screenings. In the menu, we find two sliders – blur reduction and flicker reduction – which allow you to adjust the smoothness effect to your own preferences. At lower settings, we get a more cinematic effect, with a slight choppy motion. At higher settings – the image becomes more theatrical, overly smooth. Everyone can set it to their liking.

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

The television supports Variable Refresh Rate (VRR), eliminating screen tearing, while the Automatic Low Latency Mode (ALLM) ensures that the game starts immediately without the need for manually switching settings. There is also support for Dolby Vision and HGiG, making the image quality in games even better – details are sharp, colours are natural, and contrast is perfectly balanced.

Additionally, the television offers a dedicated gaming panel that allows for quick adjustment of picture settings without the need to exit the game. It is a device that meets virtually all the requirements of a modern gamer.

The TCL C7K is a television that on paper appears to be the dream equipment for gamers – and most importantly, it also holds up in practice. To start with the good news: there are two full-bandwidth HDMI 2.1 ports, so we can easily connect both a console and a computer, making full use of their capabilities. The panel itself supports a refresh rate of 144 Hz, which provides a significant advantage in fast-paced games. Additionally, it comes with a complete set of gaming features: VRR (Variable Refresh Rate), ALLM (Auto Low Latency Mode), and support for Dolby Vision in games. There is also an HGiG mode that allows for an HDR effect in line with the creators' intentions. GameBar, which is an information bar for gamers. It works quickly, looks clear (like a Nintendo console👌), and shows the most important information: the current frame rate, VRR status, and even HDR parameters.
