TCL MQLED85 / C765 vs TCL P755

The television TCL MQLED85/C765 performs well in handling HDR. In the tested movie scenes, where the screen is at 100% brightness, the model achieves impressive results around 1000 nits, providing intense and realistic rendering of HDR content. However, similar to contrast, the dimming algorithm may show some 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 instance, 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 against a dark background, the television did not reach maximum intensity. For users expecting a perfect HDR effect in such extreme cases, the TCL MQLED may come up a bit short. However, in terms of colours, the television stands out with a very high coverage of the DCI P3 colour gamut 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 crucial for cinema image fans. Although this model achieves brightness over 1000 nits, the TCL MQLED85 may struggle to reflect details in very high-contrast scenes. For better HDR quality control, the C765 is equipped with dynamic tone mapping, making the image more realistic and natural depending on the content.

TCL P755 provides average HDR effect quality. The maximum brightness of the TV 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, affecting the overall impression of contrast. However, the TV offers wide coverage of the DCI P3 colour gamut, reaching about 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, while seeming to be the best setting from the manufacturer, is not without its flaws. The colour reproduction in HD/SDR mode MQLED85 shows certain shortcomings. In the analysis of white balance, there is a significant lack of blue colour, which can affect the overall image quality, particularly in bright scenes where blue shades are crucial for natural representation. The overall image may then appear too warm. As for gamma contrast, the graph shows that there is a large jump above the reference line of level 2.4 at the beginning, which may suggest significant dimming of brightness in darker areas, leading to loss of detail in blacks. Then for most of the time, the values are below this line, which can lead to loss of detail in the brighter parts of the image. Such a distribution may negatively impact the perceived image quality, especially when watching regular TV in HD quality.

In the case of the 4K HDR image quality of the TCL MQLED85/C765 television, there is a noticeable excess of red colour in the analysis of white balance. This excess can significantly impact the viewer's experience, leading to several notable effects. First and foremost, 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 "oversaturation," which detracts from the image's naturalness and authenticity. In terms of contrast, the EOTF (Electro-Optical Transfer Function) graph indicates that most values are above the reference line, suggesting an intense boost in brightness in the bright areas of the image. However, the exception is the start of the graph, where the EOTF line is below the reference, which may 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 the context of image settings, so it is worth considering adjusting the settings to achieve better results.

The colour reproduction in the P755 in "Cinema" mode, although it is the best factory setting, leaves much to be desired. The biggest issue is the white balance, where the chart clearly shows a spike in the red colour and a drop in the green colour. This leads to a shift in colours towards red, causing the colours on the screen to appear less natural and may look 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 shifted towards red, affecting the realism of the image and reducing the perception of colour depth. In terms of contrast, the gamma chart analysis shows significant fluctuations, particularly in the dark areas of the image, where values drop below the optimal level of 2.4. As a result, darker areas may be displayed brighter than they should be. Additionally, the EOTF curve, responsible for brightness reproduction, sits slightly above the reference curve. The graph shows a slight increase in brightness to about 50%, after which there is only a minor drop. This leads to excessive brightness enhancement in the mid-range of the image and may result in loss of detail and distortion in brighter scenes.

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

Regarding contrast, the gamma curve, responsible for HD quality, has been completely free of drops below the reference line, which means better visibility of details in dark scenes. However, 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 shows fewer errors, although some issues with reproducing mid-tones may still be noticeable. The EOTF curve measured on real film scenes still shows a significant brightness boost, so the image may appear more intense but artificially brightened. This is a typical problem for TCL brand televisions, which may appeal to untrained viewers but can frustrate those more familiar with an ideal image.

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

After calibration, the colour reproduction on the television significantly improves when it comes to SDR content. The colour curves are now close to the ideal value, and the gamma is more stable. Although the dip at the beginning of the graph to the values 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 improvements in HDR content. The white balance has been corrected, translating to 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 tonality and detail have been enhanced. Dynamic tone mapping works more effectively, improving image quality in bright areas and preserving more details.

Although the image from the device does not achieve full perfection, calibration brings significant improvement. After adjusting the settings, the television performs much better, offering 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.

We will now take another look at the tonal transitions on the TCL MQLED85/C765 TV, but in the context of lower image quality. Despite the presence of the "Gradual Smoothing" option, when set to "low", the effects are practically invisible, disappointing users who expect an improvement in image quality. On the other hand, the "high" setting yields minimal results, and worse still, it can blur important details, negatively impacting the sharpness and clarity of the displayed image. However, in the context of image scaling, the TV successfully displayed the image without overscan, meaning we do not lose any part of the view. The image looks quite decent, and details such as tree branches or the outlines of models do not show significant jaggedness, which positively affects 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 can affect the quality of tonal gradation in higher dynamic range materials.

In the case of image scaling, the television does not perform its best. There are noticeable edge cut-offs, particularly evident on the model's figure 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. Additionally, SD quality image is displayed with slight cropping at the top as well as the bottom.

TCL MQLED85/C765 is equipped with a standard refresh rate panel of 120 Hz, with the possibility of increasing it to 144 Hz when connected to a powerful computer. The television also offers a multi-level motion smoother, which is mainly aimed at users wanting to improve the fluidity of motion in films. It allows for adjusting the intensity of the effect on a scale from 0 to 10, enabling precise tailoring of the image smoothness to individual preferences. The response time of the panel is decent, but not perfect. We can observe motion blur occurring behind both dark and medium objects.

The television offers decent, though not perfect, results in terms of motion smoothness. In the case of movies, the television has a "Flicker Reduction" feature that allows for adjustment of motion smoothness on a scale from 1 to 10. With this option, we can tailor the image appearance to cinema or more theatrical preferences (with lower or higher speed).

TCL MQLED85/C765 has achieved 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), allowing the TV to automatically switch to low latency mode, minimising response time and ensuring smooth gameplay. VRR (Variable Refresh Rate) supported from 48 to 144 Hz eliminates stuttering and screen tearing in dynamic game scenes. Additionally, the TV supports the Dolby Vision Game Mode, which provides better image quality in games with exceptional depth of colour and contrast. TCL MQLED85/C765 also features a decent but not the best implementation of HGiG (HDR Gaming Interest Group), optimising the display of HDR games, however, in the case of TCL, it causes bright details to wash out, resulting in some elements merging into a white blob - more on this can be read in the colour reproduction section. It supports various resolutions such as 1080p@120Hz, 1440p@120Hz, and 4K@120Hz, allowing gamers to enjoy higher image quality and better fluidity. The Game Bar feature allows for easy switching between game settings and quick control of parameters, which significantly simplifies adjusting the TV 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, ensuring smoother and more immersive gameplay.

MQLED85/C765 is a television that combines advanced technologies and excellent support for gamers, making it the ideal choice for those looking 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 TV to low latency mode, significantly improving responsiveness 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 the tearing effect and providing smoother gameplay. Dolby Vision for gamers enhances picture quality by 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 response time.

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