TCL MQLED85 / C765 vs TCL C69K / Q6C

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, TCL C69K / Q6C is a moderate model. In optimal film conditions, it shows its full potential, achieving a maximum of around 600 nits. In scenes with large, intense light sources, the HDR effect can be truly satisfying, providing a cinematic shimmer. However, it should be noted that when managing backlight zones, there are situations where parts of the image become dimmed, and sometimes they are barely visible. This suggests that there is still a lack of proper optimisation of the algorithms; however, considering the technical parameters in this price range, the design itself still presents very well.

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.

The Filmmaker mode, which has made its debut in this year's TCL televisions (including the C69K / Q6C), is definitely the best choice "to start with." This is the mode we recommend for daily film and series viewings. Unfortunately, as is often the case, best does not mean perfect. In SDR material, the image proved to be too warm, with a pronounced red tint in the white balance. We had the opposite impression with HDR content – here the image became cooler than it should, due to an excess of blue. Additionally, there is the characteristic of brightness, which at times resulted in overexposure. In practice, this translated into quite noticeable errors in colour tests, which is difficult to accept in a mode branded as "from the creators."

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.

Through white balance correction, we were able to significantly reduce the tendency of C69K / Q6C to distort colours, which yielded a very good final result. After calibration, the issue of excessive warming of scenes in SDR and excessive cooling of the image in HDR disappeared. However, it is worth analysing the brightness characteristics more closely. While in SDR content it is hard to have major objections – the image looks really good, especially in older films, TV programmes or on YouTube – it performs significantly worse in the case of HDR content. Analysis of the EOTF curve suggests that everything is fine, yet in practice (EOTF in films) the limitations of the design itself become apparent. This model has a tendency to excessively brighten small parts of the frame, only to overly dim the entire scene in other situations. The effect of calibration is therefore undeniable, and in terms of colour reproduction, C69K / Q6C gains a lot. Unfortunately, certain limitations arising from local dimming management simply cannot be bypassed.

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.

In terms of image scaling, TCL C69K / Q6C performs quite well. Lower quality content appears acceptable, and thanks to the lack of overscan issues, the image is displayed in full without any cropping. However, one should not expect miracles – very low-quality materials will not gain a second life here, as the image processor has its limitations.

Thin lines and details exhibit characteristic tearing, which reveals the absence of more advanced image enhancement algorithms. It is also a pity that the C69K / Q6C lacks a tone transition smoothing feature. As a result, in older films or video materials, banding of colours can be visible and may become distracting during prolonged viewing.

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 use of a 144 Hz panel in TCL C69K / Q6C is a significant advantage in this price range. It represents an important step forward compared to its predecessor (C655 PRO), which only offered 60 Hz in 4K. The difference is particularly noticeable when watching sports or playing games – the ball, players, or dynamic action in games are displayed more clearly and without loss of detail. Another interesting feature is the panel's ability to work at 240 Hz (which the manufacturer does not officially mention) – we will return to this topic in relation to the PC gaming mode. TCL has also added a feature for movie fans: “Motion Clarity”. This allows users to adjust the picture to their preferences using two simple sliders. We can either keep the visible film frame or opt for very smooth, "

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.

TCL C69K / Q6C is a television that can confidently be described as equipment created with gamers in mind. Here we have 4K at 144 Hz, VRR support, automatic game mode (ALLM), and Dolby Vision Gaming. Additionally, there is a practical Game Bar, which is a panel with the most important settings conveniently at hand – useful when we want to change something quickly during gameplay (e.g. screen aspect ratio: Yes, it can be done!). The wide range of VRR, reaching up to 240 Hz, is particularly noteworthy. However, this option is mainly for PC gamers who will operate below the native 4K resolution. In that case, the television can spread its wings and show additional smoothness, especially in fast-paced e-sports titles. For consoles, we stick to the classic limit of 120 Hz, but even so, the capabilities are truly extensive. The only downside is a slight ghosting that can occasionally be seen in dynamic scenes. Other than that, C69K / Q6C offers everything that gamers expect from a television.
