TCL MQLED85 / C765 vs Philips PUS8079

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.

The maximum brightness in content with a wide tonal range at 202 nits is extremely low and practically prevents watching movies and series on streaming platforms in the highest quality. It's worth mentioning that in this case, using the HDR format equipped with dynamic metadata won't help either. Why won't it help? Because the only such format implemented in the television is HDR10+, which is extremely unpopular, and films recorded in this format are scarce. It’s also worth noting that PUS8079 uses WLED backlighting, which unfortunately is not the best solution, resulting in coverage of only 80% of the wide DCI-P3 colour gamut. The effect of this reality is significantly less intense colours in HDR content.

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 best factory mode in terms of colour reproduction and fidelity to the director's vision was "Film". While it was the best of the predefined modes, it still had significant discrepancies between what the filmmaker wanted to convey and what the tested television displayed. In both SDR and HDR materials (though to a lesser extent in the latter), the white balance, which is the most fundamental element responsible for image purity, turned out to be somewhat of a repeat of the vibrant mode, with a blue tint reminiscent of what you see in retail displays. Moving directly to the SDR materials and what affects contrast, namely gamma, we see it being severely reduced. This leads to cutting off already minimal contrast resources and brightening the entire image. In the EOTF curve, responsible for the increase in brightness pace in HDR materials, we instead see a strong drop below the reference line, which, given the limited light output of the television, significantly impacted the perception of those contents, which were even more dimmed. We won’t separate the quality assessments of the colours themselves since, in both cases, they achieved astronomical deltaE values, being simply completely different from what they should be.

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.

Luckily, Philips implements advanced image correction tools in all of its TVs. SDR content has benefited the most here, and the huge deltaE errors have been significantly corrected, with both white balance and gamma being substantially reworked. While we can't say it's reference-quality image, it's definitely better, and you can watch a movie or series without causing a headache, especially for your eyes. Naturally, HDR materials, due to the very low luminance of the TV, could not be corrected to the same high degree as those with a standard colour palette, but we managed to roughly straighten out the EOTF curve and the white balance. Unfortunately, that was all we could squeeze out of our unit, although it's worth noting that each unit is different and has entirely different errors, whether minor or major.

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.

We will return once again to the issue of tonal transitions, but in the context of overall image quality improvement. As we can observe in the photo on the left, the gradation enhancement feature works brilliantly. Furthermore, it offers several settings, and each of them, even the lowest, provides a beneficial effect, and, what’s more, does not soften the film grain effect. We will repeat once again that this feature is the biggest advantage of the tested television.

Secondly, we will look at image scaling. Here, the tested television performed worse. We can notice, above all, the strongly jagged fine details and the characteristic white glow around figures. We must not forget about the significant artificial sharpening of the image.

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.

This paragraph, unlike the others, will be extremely short. The reason for this situation is the lack of implementation of even the most basic motion smoothing function, which was to be expected given the price of the device. We also note that we are dealing with a VA panel, whose sharpness will not be the best under the sun. This type of panel is mainly associated with high contrast, which goes hand in hand with a relatively slow response time, as we can clearly read from the panel analysis results. As you can see, from the images captured in quick motion, the picture is blurred, typical for this type of panel. Although it may not be the ideal option, it can conditionally be used for watching sports, although one must keep in mind the less than optimal sharpness in motion. It's worth mentioning that movies will exhibit stuttering, as the television does not have any, not even the simplest, motion smoother.

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.

Philips PUS8079 offers only the most basic support for gaming in the form of ALLM, VRR, and Game Bar. The most important information is that thanks to the implementation of the feature responsible for dynamic refresh rate adjustment, the image is actually quite smooth for this price range and does not 'tear' the image.

A slightly greater nod towards gamers is the introduction of the Game Bar, allowing for settings adjustments 'on the fly'. This means we won’t have to exit the game to make any changes to the image. Importantly, it hasn’t been stripped of options known from higher models. We can find features such as shadow enhancement for better visibility in shadows and a colour filter for players with visual impairments.
