TCL MQLED85 / C765 vs TCL P755

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.

TCL P755 provides average HDR effect quality. The maximum brightness of the television is slightly below 300 nits. Such brightness limits the intensity of bright areas in HDR content. In practice, this means that bright elements may not be sufficiently pronounced, which affects the overall impression of contrast. However, the television offers a wide coverage of the DCI P3 colour gamut, reaching around 93%. As a result, colours are vibrant and saturated, significantly improving colour reproduction quality in HDR content. Despite the limited brightness, the wide colour range allows for richer and more realistic shades.

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 colour reproduction in the P755 in "Movie" mode, although it is the best factory setting, leaves much to be desired. The biggest problem is the white balance, where the graph clearly shows a spike in red and a drop in green. This leads to a shift in colours towards red, making the colours on the screen less natural and potentially looking incorrect, especially in scenes with a white or neutral background. This is confirmed by the "Colour Checker" test, which reveals that the colours are indeed skewed towards red, affecting the realism of the image and reducing the perception of colour depth. In terms of contrast, the gamma chart analysis shows considerable fluctuations, particularly in dark areas of the image, where values drop below the optimal level of 2.4. This results in darker areas being displayed brighter than they should be. Additionally, the EOTF curve, responsible for brightness reproduction, is slightly above the reference curve. The graph shows a slight boost in brightness to around 50%, followed by only a minor decrease. This leads to excessive brightness enhancement in the mid-tones of the image and may result in loss of detail and distortion in brighter scenes.

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 colour reproduction on the television improves significantly when it comes to SDR content. The colour curves are now close to the ideal value, and the gamma is more stable. Although the drop at the beginning of the graph to value is still present, the overall accuracy of colour reproduction is much better. The "Colour Checker" test shows that most colour samples have errors below level 2, indicating improved colour fidelity. A few deviations are present, but generally, the colours are now more realistic and consistent with reality.

Calibration also brings improvement in HDR content. The white balance has been improved, resulting in a more natural colour reproduction. The EOTF curve, although now closer to the reference curve, still shows a slight boost in brightness at the beginning of the graph. This leads to minor distortions in very bright scenes, but the overall tonal quality and detail have been enhanced. Dynamic tone mapping works more effectively, improving image quality in bright areas and retaining more detail.

Although the device's picture does not achieve complete perfection, calibration brings significant improvement. After adjusting the settings, the television presents itself much better, offering a more realistic and accurate colour reproduction in SDR and HDR content. While some shortcomings can still be noticed, calibration effectively eliminates many previous issues, ensuring better image quality and more natural colours.

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 "Gradual Smoothing" function works quite well, effectively eliminating visible boundaries between different shades of the same colour. Thanks to it, tonal transitions are smoother. Unfortunately, this function is not available in HDR mode, which may affect the quality of tonal gradations in higher dynamic range materials.

When it comes to image scaling, the television does not perform at its best. There are noticeable edge cuts, particularly evident on the figure of the model and the branches of trees. The blurring of details in these areas affects the overall sharpness of the image. This may be noticeable when watching content in a lower resolution. Moreover, SD quality images are displayed with slight cropping at the top as well as the bottom.

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 television offers decent, although not perfect, results in terms of motion fluidity. For films, the television features a “Flicker Reduction” function that allows for motion fluidity adjustment on a scale from 1 to 10. With this option, we can customise the appearance of the image to a cinematic or more theatrical preference (with a slower or faster pace).

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 device offers a range of features useful for gamers, such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), Dolby Vision for gamers, and Game Bar. ALLM automatically switches the television to low latency mode, significantly improving response to commands from the controller and minimising input lag. VRR synchronises the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and providing smoother gameplay. Dolby Vision for gamers enhances picture quality, offering better colour and contrast reproduction in games that support this format. The Game Bar feature allows quick access to game settings and monitoring of key parameters such as reaction time.

However, the television has certain limitations. The 60 Hz panel prevents the display of higher refresh rate signals at various resolutions, which may affect the smoothness of the image in dynamic games. Additionally, the lack of support for G-Sync technology for PC may impact gameplay quality on a computer. It is also worth noting that the HGiG mode, which aims to improve picture quality in HDR games, does not function correctly in this model, negatively affecting the visual experience in HDR-supported games.
