TCL MQLED85 / C765 vs Sony BRAVIA 2 II (S25M2)

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.

Sony Bravia 2 II is not a very bright TV and unfortunately that is immediately apparent in HDR. In our measurements brightness stayed around 300 to 330 nits, which is definitely too low for the brightest parts of the picture to look truly impressive. In practice HDR here does not differ that much from ordinary SDR. Bright highlights, the sun, or lamps are of course visible, but they lack the intensity you would expect from HDR material. The Bravia 2 II therefore performs much better with regular SDR content, and it is in that use case that its limited brightness will be least noticeable.

Color gamut coverage

Sony Bravia 2 II also doesn't impress when it comes to colors. The TV doesn't use any additional gamut-expanding filter, such as the quantum dots found in QLED TVs or a PFS phosphor layer. In our measurements DCI-P3 coverage was about 78%, and the very wide BT.2020 around 57%. That's definitely too little to talk about truly saturated colors in HDR content. More intense reds, greens, or turquoise hues will simply be less striking than on TVs with an expanded color gamut. The Bravia 2 II therefore fares much better with standard Rec.709, the gamut used for movies, series, and TV in SDR.

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.

Out-of-the-box color reproduction in Cinema mode was really good, at least for ordinary SDR material. The Bravia 2 II had a slight tendency to boost reds, so some colors skewed a bit warmer, at times with a faint pinkish tint. However, it wasn't a major fault, and during normal viewing the picture still looked quite natural. There was a bit more going on with image brightness. Looking at the gamma trace, you can see Sony doesn't stick exactly to the reference value. The darkest parts are slightly lifted, while as brightness increases the gamma gradually rises and a larger portion of the image becomes darker than it should. That said, the difference isn't large enough to seriously interfere with everyday viewing. Overall, SDR straight out of the box performs pretty well.

The situation is much worse in HDR. We already mentioned the limited color gamut, but the Bravia 2 II also manipulates image brightness quite aggressively here. The EOTF curve sits below the reference for a large part of the range, which means the TV renders most midtones and brighter parts of the scene darker than the source material intends. Only toward the very end of the range does the curve flatten out, as the panel reaches the limits of its capabilities. Combined with a peak brightness of around 300 nits, this results in HDR that not only lacks punch but can simply look too dim.

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.

Calibration did a lot for the Bravia 2 II, especially with SDR content. Above all, we were able to even out the white balance and tidy up the gamma, which now sticks much closer to reference values. As a result, the picture no longer has the previous pink tint, and the brightness of individual areas is much better balanced. You can also see this in the color errors, which dropped to a very low level after calibration (with minor issues in the most saturated reds).

We also partially tamed the Bravia 2 II in HDR, particularly in how the TV manages image brightness. However, there is one thing no calibration can fix: the panel's inherent limitations. The narrow color gamut means the TV physically cannot reproduce the most saturated colors present in HDR content. On top of that, the IPS panel's low contrast leaves darker scenes veiled by a grayish glow, causing colors to lose some of their depth. So we can improve how the Bravia 2 II uses its capabilities, but unfortunately we can't overcome the panel's fundamental limits.

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.

Upscaling in the Bravia 2 II performs quite well, and in that respect the TV maintains the standard Sony has accustomed us to. Lower-resolution content is sensibly scaled to 4K, with the image slightly smoothed and without over-sharpening edges. It’s a different story when it comes to improving content with visible compression. That’s handled by the "Digital Noise Reduction" feature, which on the "High" setting can indeed smooth out some ugly tonal banding. The problem is it does so fairly aggressively, removing a lot of fine detail along with the imperfections, including natural film grain. Moreover, when there’s more motion on screen its effectiveness drops significantly and the improvement becomes minimal. So we generally avoided using this feature in everyday viewing.

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.

The Bravia 2 II uses a 60 Hz panel and, given its capabilities, handles motion quite well. However, keep in mind this is a basic panel, and its limitations are already noticeable, especially with sports. The TV cannot interpolate 50/60 fps content to a higher refresh rate, so it can't further improve the sharpness of fast-moving objects. For movies and series, you get a standard motion smoother that can reduce the characteristic judder of material shot at 24 fps.

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 Bravia 2 II is not a TV particularly well suited for gaming, and the feature list makes that clear pretty quickly. You basically only get automatic low-latency mode (ALLM) and a simple Game Bar where you can view basic signal information and change a few settings. But that's where the list of advantages ends. The TV doesn't support VRR or 120 Hz (not even at lower resolutions), and on top of that it has problems with a proper implementation of the HDR HGIG format. It can, of course, be used for occasional console gaming, and thanks to low input lag controls stay responsive, but if you're mainly looking for a TV for gaming, the Bravia 2 II will simply be a very limited choice.
