TCL MQLED85 / C765 vs TCL C7K / QM7K 55"-85"

The television TCL MQLED85/C765 handles HDR well. In the tested movie scenes where the screen is covered with 100% brightness, the model achieves impressive results of around 1000 nits, providing intense and realistic rendering of HDR content. However, similar to contrast, the dimming algorithm may exhibit certain limitations. Despite a large number of Mini LED zones, the television does not always manage to "wow" the user with brightness in very challenging test scenes. For example, in the scene from the film "Life of Pi," where a bright moon appears against a dark background, and in another scene from "Sicario 2," where a very bright light effect is visible on a dark background, the television did not reach maximum intensity. For users expecting perfect HDR performance in such extreme cases, the TCL MQLED may be slightly disappointing. However, in terms of colours, the television stands out with very high coverage of the DCI P3 colour palette at 95%, which is an impressive result, comparable to much more expensive models. TCL MQLED85 / C765 offers support for various HDR formats, including Dolby Vision and HDR10+, which is significant for cinema image enthusiasts. Although this model achieves brightness over 1000 nits, TCL MQLED85 may struggle to reflect details in very high-contrast scenes. For better HDR quality control, C765 is equipped with a dynamic tone mapping option, making the image more realistic and natural depending on the 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 television TCL MQLED85/C765 was tested in movie mode, which, although it seems to be the best setting from the manufacturer, is not without flaws. The colour reproduction in HD/SDR mode MQLED85 shows some shortcomings. In the analysis of white balance, there is a significant lack of blue, which can affect the overall image quality, especially in bright scenes where blue shades are crucial for natural representation. The overall shape of the image may then appear too warm. Regarding gamma contrast, the graph shows a large jump above the reference line of 2.4 at the beginning, which may suggest significant dimming of brightness in darker areas, leading to loss of detail in black. Then, for most of the time, the values lie below this line, which may lead to loss of detail in brighter parts of the image. Such a distribution can negatively impact perceived image quality, particularly when watching regular television in HD quality.

In the case of 4K HDR image quality of the TCL MQLED85/C765, there is a noticeable excess of red in the analysis of white balance. This excess can significantly affect the viewer's experience, leading to several significant effects. Firstly, an excessive amount of red can make other colours, such as green or blue, appear muted or unnatural. This distortion of colour balance can result in an overall impression of "over-saturation," which detracts from the naturalness and authenticity of the image. As for contrast, the EOTF (Electro-Optical Transfer Function) graph indicates that most values are above the reference line, suggesting an intense boost in brightness in bright areas of the image. However, there is an exception at the beginning of the graph, where the EOTF line is below the reference line, which can lead to excessive dimming of small light elements.

Users should be aware that despite using the best mode, which is movie mode, the television is not free from flaws in terms of image settings, so it is worth considering adjusting the settings to achieve better results.

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 the professional calibration of the television TCL MQLED85/C765, its colour properties in movie mode have significantly improved, resulting in a much more satisfying visual experience. Both in SDR and HDR modes, the white balance shows no serious errors, and the graph appears much better harmonised. Users can now enjoy natural colour reproduction, which is crucial for obtaining an authentic experience when watching films. It is worth noting that in HDR content, there may be slight colour reproduction errors at the end of the graph, but these are much smaller than before calibration. As a result, characters and landscapes become more realistic, enhancing the depth of immersion in the story.

In terms of contrast, the gamma curve, responsible for HD quality, has been completely free of drops below the reference line, meaning better detail visibility in dark scenes. Nevertheless, there is still a slight boost at the beginning of the graph, which may affect the perception of bright elements. For HDR content, the EOTF curve also exhibits smaller errors, although certain issues with medium tone reproduction may still be noticeable. The EOTF curve measured on actual movie scenes still shows a significant brightness boost, making the image appear more intense but artificially brightened. This is a typical problem for TCL televisions, which may appeal to inexperienced viewers, but can be irritating for those more familiar with an ideal image.

What benefits does professional calibration bring for film enthusiasts? Thanks to it, viewing becomes even more realistic and immersive, and each scene can be fully experienced, preserving details and natural colours.

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.

Let’s take another look at the tonal transitions in the TCL MQLED85/C765 television, but in the context of poorer image quality. Despite the presence of the "Gradual Smoothing" option, when set to "low," the effects are practically invisible, disappointing users expecting an improvement in image quality. On the other hand, the "high" setting produces minimal results, and worse still, it can blur significant details, negatively affecting the sharpness and clarity of the displayed image. However, in the context of image scaling, the television successfully displayed the image without overscan, meaning we do not lose any part of the view. The image looks rather decent, and details such as tree branches or the outlines of models do not exhibit significant jaggedness, which positively impacts the visual quality.

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.

TCL MQLED85/C765 is equipped with a panel featuring a standard refresh rate of 120 Hz, with the capability to increase to 144 Hz when connected to a powerful computer. The television also offers a multi-level motion smoother, primarily aimed at users wishing to enhance motion fluidity in films. It allows for the adjustment of effect intensity on a scale from 0 to 10, enabling precise tuning of image smoothness to individual preferences. The response time of the panel is decent, but not perfect. We can observe blurring occurring behind both dark and medium objects.

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.

TCL MQLED85/C765 has received an impressive rating in the gaming features category, making it an excellent choice for gaming enthusiasts. The television supports all the latest technologies that significantly enhance the gaming experience. Among the key gaming features is ALLM (Auto Low Latency Mode), which automatically switches the TV to low-latency mode, minimising response time and ensuring smooth gameplay. VRR (Variable Refresh Rate) functioning in the range of 48 to 144 Hz eliminates stuttering and screen tearing in dynamic game scenes. Additionally, the TV supports Dolby Vision Game Mode, which provides better image quality in games with exceptional colour depth and contrast. TCL MQLED85/C765 also features a decent if not the best implementation of HGiG (HDR Gaming Interest Group), optimising HDR game display; however, for TCL, it causes detail in whites to be brightened, resulting in some elements merging into a white blob - we can read more about this in the colour reproduction section. It supports various resolutions, such as 1080p@120Hz, 1440p@120Hz, and 4K@120Hz, allowing players to enjoy higher image quality and better fluidity. The Game Bar feature allows easy switching between game settings and quick parameter control, greatly simplifying the adjustment of the television to individual needs. With support for G-Sync and FreeSync technologies, users of NVIDIA and AMD graphics cards will be pleased with the refresh rate synchronisation capabilities, eliminating tearing and stuttering issues, thereby providing a smoother and more immersive gaming experience.

MQLED85/C765 is a television that combines advanced technologies and excellent support for gamers, making it the perfect choice for those who wish to maximise their gaming experiences.

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.
