TCL MQLED85 / C765 vs Hisense UR8S

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.

UR8S is a slightly higher-end Mini-LED, so you could expect a lot in terms of brightness. And indeed, on a synthetic test pattern peak brightness reached around 2200 nits. That’s a very good result, but as always what’s much more important is what the TV does in normal film scenes. Here the results are a bit more uneven. In bright scenes, where there’s a lot of light on screen, the UR8S can deliver really strong HDR. Brightness then reaches about 1500 nits, so the image is very intense and has plenty of punch. It’s worse with small bright elements on a dark background. The TV clearly dims them to keep good blacks and to prevent excessive bloom. As a result things like single stars or tiny reflections can be only around 200 nits. And here HDR is no longer as impressive. So you can see that the local dimming algorithm works effectively, but it also has its cost: sometimes it simply sacrifices the brightness of small details in favour of contrast.

Colours

With RGB Mini-LED TVs colours should be judged a little differently than usual. If we look solely at the panel’s native capabilities, the UR8S performs excellently. We measured around 94% coverage of BT.2020 and practically full DCI-P3. These are among the highest values currently found in LCD TVs and this is where the potential of the RGB backlight is most obvious. The problem is that this potential is not always realised in real scenes. When we ran the same measurements on test patterns with a film background applied, saturation of some colours began to fall noticeably. Individual zones are not always able to control the three RGB components so precisely when the scene becomes more complex. This is most visible with blue and magenta. On simple test patterns they can look very strong, but in more demanding scenes samples of those colours visibly shrink. So the UR8S’s capabilities are enormous, it’s just that the TV cannot fully make use of them in every scene.

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.

For assessing the out-of-the-box colours we used Filmmaker mode, which is intended to show an image that is as close as possible to how the material was prepared. Looking at the white balance alone, the UR8S performs quite well. There is no strong tint that immediately jumps out, although as brightness increases a little too much blue and red start to appear, with a simultaneous shortfall of green. Colour errors therefore show up in measurements, but the image itself does not look bad. We have far greater reservations about how the UR8S manages picture brightness. In SDR the gamma sits around 1.9–2.0 for most of the range instead of the target 2.4. In practice this simply means the picture is too bright, especially in the midtones. Shadows are lifted too much, causing the image to lose some depth. A similar tendency is visible in HDR. The EOTF curve is above the reference value for a large part of its range, so the UR8S again brightens the image more than it should. This is not due to a lack of brightness — the TV has plenty — but to the way it manages that brightness. As a result, HDR content can look very striking, but not always precisely as it should.

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.

Hisense provides plenty of calibration options and, in SDR, these can yield a very good result. After calibration, the white balance is practically even across the entire range, and colour errors fall to very low values. The UR8S can be adjusted very precisely here. HDR is somewhat different. The white balance itself can also be noticeably improved, although at the highest brightness levels larger deviations begin to appear. The most interesting aspect, however, is the behaviour of the EOTF curve. Even after it has been correctly set on test patterns, the UR8S still tends to interpret brightness in its own way when watching films. Depending on the scene, parts of the image are slightly brightened while others are dimmed relative to how they should appear. This shows that the algorithms controlling the local dimming have a significant influence on the final image. Calibration therefore allows colours to be improved very effectively, but we are not able to completely 'turn off' the way the UR8S manages brightness in HDR.

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.

A big plus of the UR8S is the use of the MediaTek Pentonic 800 processor, and digital image processing is one of this model's stronger points. The TV handles smoothing tonal transitions very well, especially with lower-quality content. The feature responsible for this effect works effectively without overprocessing the picture. Even on the medium setting it can noticeably reduce visible banding and unevenness without heavily blurring details. Upscaling itself also performs very well. Lower-resolution content is displayed cleanly, edges look natural, and the image is not overly sharpened. The UR8S simply copes very well with a weaker signal, and in this respect it is one of its most notable strengths.

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 UR8S is equipped with a panel with a native 180 Hz refresh rate, so right from the start it offers excellent motion handling. The panel itself performs really well here, although some limitations typical of VA panels are still visible. Motion blur is relatively minor for this type of screen, but with faster motion (especially on darker backgrounds) it can still be noticed, particularly when compared with the same image on OLED TVs.

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.

In terms of gamer features the UR8S performs really well. The TV supports practically everything you can expect from a modern console or PC display. It offers ALLM, VRR and 4K at 120 Hz. There is also Dolby Vision in Game Mode, so when using, for example, the Xbox Series X you do not have to give up that HDR format. PC gamers get even more options. The panel can run at 4K at 180 Hz, and dropping to Full HD can raise the refresh rate to as much as 330 Hz. There is also a Game Bar that lets you quickly check key information and change gaming-related settings. The only clear omission is a correct implementation of HGiG. With it enabled the TV still alters HDR brightness mapping, so we do not get the effect intended by that standard. Aside from that, the UR8S is very well prepared for both consoles and a powerful PC.
