TCL MQLED85 / C765 vs Dreame S100

The TCL MQLED85/C765 television performs well with HDR handling. In the tested movie scenes, where the screen is covered at 100% brightness, the model achieves impressive results around 1000 nits, providing intense and realistic representation of HDR content. However, similar to contrast, the dimming algorithm may show some limitations. Despite the large number of Mini LED zones, the television does not always manage to "stun" the user with brightness in very challenging test scenes. For example, in a scene from "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 perfect HDR performance in such extreme cases, the TCL MQLED may be slightly disappointing. However, regarding colors, the television stands out with a very high color gamut coverage of DCI P3 at 95%, which is an impressive result comparable to much more expensive models. The TCL MQLED85 / C765 offers support for various HDR formats, including Dolby Vision and HDR10+, which is essential for cinema image enthusiasts. 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 Dreame S100 is a relatively bright television. In movie mode, the brightness we measured reached about 600 nits. This is a really good result, although not the highest, considering the capabilities of the competition in this price range. In fullscreen scenes, it is evident that the television can generate an image that strikes with brightness. Unfortunately, when more complex scenes appeared on the screen, the local dimming algorithm in this model tried above all to maintain the deepest blacks. However, this came at the expense of HDR effect – and in a drastic way. In such scenes, the brightness of bright elements dropped below 100 nits, which is a truly tragic result, far from any HDR effect. This aspect can be improved, though not without any "buts." It is enough to change the local dimming setting in the television's menu, but then the blacks in such scenes simply turn gray. It’s a pity that Dreame could not refine the local dimming algorithms better, and the S100 is another example that the mere number of local dimming zones does not always translate into better image quality. As a consolation, it is worth adding that the Dreame S100 is advertised as a "QLED" television, although in reality it utilizes a PFS LED filter. As a result, the colors are appropriately saturated, and the color gamut coverage we measured exceeded 94% of the DCI-P3 palette.

TheTCL MQLED85/C765 television was tested in movie mode, which, although it seems to be the best setting from the manufacturer, is not without flaws. The color reproduction in HD/SDR mode MQLED85 shows certain shortcomings. In the analysis of white balance, there is a significant lack of blue color, which can affect the overall picture quality, especially in bright scenes where blue hues are crucial for natural representation. The overall image may then seem too warm. As for gamma contrast, the graph shows a significant jump above the reference line of level 2.4 at the beginning, which may suggest significant dimming of brightness in darker areas, leading to a loss of detail in blacks. Then, for most of the time, the values are below this line, which can lead to a loss of detail in the brighter parts of the image. Such a distribution can negatively affect the perceived image quality, especially when watching regular HD television.

In the case of 4K HDR image quality of the TCL MQLED85/C765, there is a noticeable excess of red color in the analysis of white balance. Such an excess can significantly affect the viewer's experience, leading to several significant effects. First of all, too much red can make other colors, such as green or blue, appear muted or unnatural. This distortion of color balance can result in an overall impression of "oversaturation," which detracts from the image's naturalness and authenticity. Regarding 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 beginning of the graph, where the EOTF line is below the reference one, 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 picture settings, so it is worth considering adjusting the settings to achieve better results.

We tested the Dreame S100 in "movie" mode and definitely recommend using this setting for watching all kinds of content. Interestingly, in the deeper settings of the TV, we also find a dedicated "Filmmaker" mode, which is available today from almost every manufacturer. However, in the case of the Dreame S100, we do not recommend using it – it blocks all image-related settings and does not allow any configuration in the menu - not even motion smoothing. So how do the factory colors perform on the S100? Not too bad, but also not great. The TV itself was quite heavily tinted with blue components, which is clearly visible in our white balance measurements. This caused the image to be artificially brightened, and the colors had a slight bluish tint. This is confirmed by the Color Checker palette, which showed how color samples leaned towards blue, generating quite significant color errors. The image in HDR mode looked definitely better, where color errors were not as prominently visible, though they still fell far from ideal. Here, the white balance was also too heavily skewed towards the blue color, which caused quite significant errors in color reproduction.

After professional calibration of the TCL MQLED85/C765 television, its color properties in movie 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 much better harmonized. Users can now enjoy natural color reproduction, which is essential for achieving an authentic experience while watching movies. It is worth noting that in HDR content, there may be minor color reproduction errors at the end of the graph, but they are significantly smaller than before calibration. This makes characters and landscapes 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 detail visibility 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 smaller errors, although certain issues in reproducing midtones may still be noticeable. The EOTF curve measured on real film scenes still shows a significant brightness boost, making the image appear more intense but artificially brightened. This is a typical issue for TCL brand televisions, which may appeal to untrained viewers but can be annoying for those more familiar with the ideal picture.

What benefits does professional calibration bring for movie enthusiasts? Thanks to it, watching becomes even more realistic and immersive, allowing every scene to be experienced fully, maintaining details and natural colors.

The Dreame S100 turned out to be a device very susceptible to professional calibration. In its menu, we found a whole array of advanced options that allowed us to effectively correct factory errors. Thanks to advanced white balance correction – both in SDR and HDR content – we completely eliminated excess blue components. The image immediately became much more natural and pleasant to view. After fully tuning the colors, errors in the Color Checker test dropped below Delta E values of 2-3. For the average viewer, this means that any color distortions have become nearly impossible to notice with the naked eye. This is a really nice surprise, as often new brands in the television market have significant problems with proper implementation and functioning of sliders in the calibration menu. Here, everything worked as it should. The only thing we need to criticize is the way the television manages its brightness in HDR. Due to the specific nature of the local dimming algorithms, we observed anomalies in the EOTF curve we measured. In the areas where high highlights should appear, there is a slight uplift of the curve above the reference line. In practice, this results in unnatural brightening of some of the brightest elements in movies or games. Despite this minor flaw, professional calibration brings a huge, very positive change to this model.

We will now take another look at the tone 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, setting it to "high" brings minimal results, and worse, it can blur significant details, negatively affecting the sharpness and clarity of the displayed image. However, in terms of image scaling, the television successfully displayed the image without overscan, which means 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 fraying, which positively influences the visual quality.

The scaling and digital processing in the Dreame S100 is handled by a technology that the manufacturer proudly calls Dreamind™ Pro AI. However, it is essential to clarify that this is not a proprietary processor but merely a marketing name for a chip from MediaTek – specifically, the model MT5889. Unfortunately, we are talking about quite an outdated unit, from the time when MediaTek lagged significantly behind the competition in terms of performance. This, unfortunately, has a direct impact on the image, as this chip is responsible for that as well. The upscaling in the S100 is rather mediocre, and the processor tends to strongly and artificially sharpen edges (fortunately, this can be somewhat tempered with the sharpness slider in the menu). In the options, we also find a "Contour Smoothing" function, which theoretically is supposed to improve tonal transitions. In practice, it brings almost no improvement – setting it to any level rarely eliminates visible color banding but can unnecessarily blur elements of the image that should remain sharp.

A separate problem is the phenomenon of overscan (clipping the edges of the frame), which is almost always visible here. Although there is an option to set the screen to display the full frame in low-resolution materials, it requires activating the aforementioned Filmmaker mode. And as you already know, this mode completely blocks any other adjustments in the image menu. In our test tables, we noted that the television offers the option to disable overscan, as technically such a feature exists in the system – however, in everyday use, with reasonable image settings, you will not be able to take advantage of it.

TCL MQLED85/C765 is equipped with a standard refresh rate matrix of 120 Hz, with the possibility of increasing it to 144 Hz when connected to a powerful computer. The television also offers a multi-stage motion smoother, which mainly serves users who want to improve motion smoothness in films. It allows for the adjustment of the effect's intensity on a scale from 0 to 10, enabling precise matching of image smoothness to individual preferences. The matrix's response time is decent but not perfect. We can observe ghosting occurring behind both dark and medium objects.

When it comes to motion fluidity, the Dreame S100 performs really well. It features a panel with a 144 Hz refresh rate, although in reality, the vast majority of users using it in a traditional way will still be limited to 120 Hz (because today's equipment, apart from PCs, only allows for such values). Thanks to the high refresh rate, the image in motion remains really sharp, largely due to the well-functioning MEMC fluidity enhancer. In the menu, we find predefined modes that allow the TV to efficiently add artificial frames, which effectively improves the fluidity of dynamic sports shots, but also helps get rid of image stuttering in film and series materials recorded at 24 frames.

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 television to low latency mode, minimizing response time and ensuring smooth gameplay. VRR (Variable Refresh Rate) supported in the range from 48 to 144 Hz eliminates stuttering and screen tearing in dynamic gaming scenes. Additionally, the television supports Dolby Vision Game Mode, which provides better image quality in games with exceptional color depth and contrast. TCL MQLED85/C765 also features a decent but not the best implementation of HGiG (HDR Gaming Interest Group), optimizing HDR game display, but in the case of TCL, it causes bright details in white, resulting in some elements blending into a white spot - we can read more about this in the color reproduction section. It supports various resolutions such as 1080p@120Hz, 1440p@120Hz, and 4K@120Hz, allowing gamers to take advantage of higher image quality and better fluidity. The Game Bar feature allows for easy switching between game settings and quick control of parameters, significantly facilitating 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 synchronization of refresh rates, eliminating tearing and stuttering issues, providing a smoother and more immersive gameplay experience.

MQLED85/C765 is a television that combines advanced technologies and excellent support for gamers, making it an ideal choice for those who want to maximize their gaming experiences.

The Dreame S100 seems almost like the perfect screen for gamers. The TV is equipped with 2 HDMI 2.1 ports with a bandwidth of 40 Gbps, which means that features such as Auto Low Latency Mode (ALLM) and Variable Refresh Rate (VRR) synchronization in the range of 48-144 Hz work seamlessly on consoles. It also has a well-designed game panel (Game Bar) that allows you to continuously check the most important parameters – from active picture modes to the number of frames rendered by the console, and even the ability to add a crosshair in the center of the screen. All of this looks great on paper, but the biggest issue with the S100 is the implementation of HDR mode in games. The TV does not have a properly implemented HGiG format. As a result, an unsuspecting user may incorrectly configure the console during the initial setup of the display. A wrong configuration can lead to a picture that is too dark or too bright (as a guideline: we suggest setting the brightness in the Xbox console menu to about 600 nits, and in the PS5 to 12 clicks). The Dolby Vision format is also problematic; it often just would not activate at all when using the XBOX – Dreame S100 line. And when it was managed to be activated, gaming was impossible due to a very high input lag that often exceeded 100ms. If the manufacturer can improve the HDR issue in games through an update, the S100 will be truly excellent equipment for gamers. For now, however, one must reckon with compromises.
