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

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.

Sony Bravia 2 II isn't a particularly bright TV and unfortunately that's immediately obvious in HDR. In our measurements brightness stayed around 300 to 330 nits, which is far too low for the brightest parts of the image to look truly impactful. In practice HDR here doesn't differ that much from regular SDR. Bright highlights, the sun or lamps are of course visible, but they lack the intensity you'd expect from HDR content. The Bravia 2 II is therefore much better suited to standard SDR material, where its limited brightness will be least noticeable.

Colour gamut coverage

The Sony Bravia 2 II also doesn't impress when it comes to colour. The TV doesn't use any extra gamut-expanding filter, such as the quantum dots found in QLED sets or a PFS phosphor layer. In our measurements it covered about 78% of the DCI-P3 gamut and roughly 57% of the very wide BT.2020. That's definitely too little to deliver truly saturated colours in HDR material. More intense reds, greens or turquoises will simply be less striking than on TVs with an expanded colour gamut. The Bravia 2 II is much better matched to the standard Rec.709 gamut used for films, series and SDR broadcast.

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 out-of-the-box colour reproduction in Kino mode was really quite good, at least for ordinary SDR material. The Bravia 2 II had a slight tendency to boost reds, which made some colours lean a bit warmer, at times with a faint pinkish tint. That wasn't a major fault and during normal viewing the picture still looked fairly natural. There was a bit more going on with image brightness. Looking at the gamma curve, Sony doesn't stick perfectly to the reference value. The darkest areas are slightly lifted, while as brightness increases the gamma gradually rises and a large part of the image becomes darker than it should. However, the difference isn't big enough to seriously bother during everyday watching. Overall, SDR straight out of the box performs quite decently.

The situation is much worse in HDR. We've already mentioned the limited colour gamut, but on top of that the Bravia 2 II quite aggressively manipulates image brightness. The EOTF curve sits below the reference for much of the range, which means the TV renders most mid and brighter parts of the scene darker than the source material intends. Only towards 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 gives HDR that not only lacks much punch but can simply look too dark.

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.

Calibration did a lot for the Bravia 2 II, especially with SDR content. Above all, we managed to even out the white balance and tidy up the gamma, which now stays much closer to the reference value. As a result, the image no longer has the earlier pink cast, and the brightness across different areas is much better organised. You can also see it in the colour errors, which after calibration dropped to a very low level (with only minor issues in the most saturated reds).

We also partly managed to rein in the Bravia 2 II in HDR, especially in the way the TV handles image brightness. However, there is one thing no calibration can fix: the panel's capabilities. A narrow colour gamut means the TV physically can't reproduce the most saturated colours recorded in HDR content. On top of that, the low contrast of the IPS panel causes darker scenes to be covered in a grey haze, which robs colours of some of their depth. So we can improve how the Bravia 2 II uses its capabilities, but we can't overcome the panel's inherent limitations.

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.

Upscaling on the Bravia 2 II performs quite well and the TV maintains the standard we've come to expect from Sony. Lower-resolution material is sensibly upscaled to 4K, and the image is slightly smoothed without excessive edge sharpening. It's less successful at dealing with content that shows visible compression artefacts. That's down to the "Digital Noise Reduction" function, which on the "High" setting can smooth some ugly banding. The problem is it does so quite aggressively and, along with the imperfections, removes a lot of fine detail, including natural film grain. What's more, when there's more motion on screen its effectiveness drops considerably and the improvement is minimal. For that reason we generally didn't use this feature for everyday viewing.

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.

Bravia 2 II uses a 60 Hz panel and, for what it is, handles motion quite well. However, bear in mind it’s an entry-level panel and its limitations are especially noticeable with sports. The TV can’t interpolate 50/60 fps material to a higher refresh rate, so it can’t further improve the sharpness of fast-moving objects. For films and series there’s a conventional motion-smoothing feature that can reduce the judder typical of 24 fps material.

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 Bravia 2 II isn’t a TV that’s particularly suited to gaming, and the feature list makes that clear pretty quickly. You basically only get automatic low-latency ALLM and a simple Game Bar where you can view basic signal info and change a few settings. That’s where the positives end. The TV doesn’t support VRR or 120 Hz (not even at lower resolutions) and on top of that it has problems correctly implementing HDR HGIG. It’s fine for occasional console play and, thanks to low input lag, the controls remain responsive, but if you’re after a TV primarily for gaming the Bravia 2 II is a significantly limited choice.
