TCL C75B vs SONY BRAVIA 3 II (XR35M2)

During our test, the TCL C75B "spat out" around 380 nits of brightness. We recorded similar results while watching most of the films we tested. They can be considered average – the television does not perform poorly in this segment, but around 400 nits is definitely too low to fully experience the magic of HDR effects. Of course, these results are better than those of budget models, which can achieve almost half the brightness values. However, for HDR enthusiasts seeking stronger lighting effects and greater realism, the C75B may prove insufficient. On the positive side, it's worth mentioning the DCI-P3 colour gamut coverage of 95%. This is a very good result that easily suffices to enjoy a wide range of colours in content available on popular streaming platforms. Vivid and rich colours are definitely a strong point of this model.

Bravia 3 II is certainly not a TV that tries to impress with brightness. In our measurements it reached about 450 nits, so it falls well short of the brightest models on the market. That does not mean HDR is just a paper feature. Compared with ordinary SDR material, the brightest elements of the image can already come through noticeably, and reflections, highlights and stronger exposures have a bit more energy and stand out better from the rest of the scene. This is most obvious in simpler shots where the screen displays many bright elements. Then the Bravia 3 II can give a hint of a higher dynamic-range picture. The problem only begins with more demanding content, where much greater brightness headroom is required. There the TV quickly shows its limitations and instead of powerful, striking HDR we get only a competently rendered picture.

Colours

Bravia 3 II uses a QLED-type panel, although technically it does not use a classic quantum dot layer. Instead Sony has used a solution based on PFS phosphor, which performs a very similar role: it allows more saturated reds and greens and thus enables a much wider colour gamut. In measurements DCI-P3 coverage was around 94%, and the very wide BT.2020 around 74.4%. These are good results for this class of hardware, which mean the Bravia 3 II has no problem reproducing sufficiently saturated colours in HDR content. Colours do not look washed out, and more intense hues can look genuinely attractive.

TCL C75B offers several picture modes, but in our opinion, the best choice is the “Film” mode. Although its settings are quite decent, the television struggles with some colour reproduction issues. In our tests, we noticed that the image had a noticeably pinkish tint compared to what could be considered accurate. This effect was particularly evident in skin tones, which appeared unnaturally flushed. The main culprit for this phenomenon turned out to be the white balance, characterised by an excessive amount of blue and red in both HD and 4K HDR materials.

An additional problem was the way brightness was rendered. The gamma, which is responsible for the visibility of details in darker materials, was definitely boosted, causing details in the darkest parts of the screen to be invisible, disappearing into complete blackness (e.g., the lower part of the screen in the comparison photo - around the actress's ear). Similarly, the situation was reflected in the EOTF curve, which was below the correct value, suggesting that we might encounter a similar problem in 4K HDR content.

Thanks to our experience and the right tools, we decided to take matters into our own hands and see how much we could extract from this model after professional calibration. We describe the details in the next section.

In Professional mode the Bravia 3 II already delivers a fairly good level of colour reproduction straight out of the box. In SDR the most noticeable issue is a slightly low gamma, which makes the midtones a little brighter. White balance isn't perfect either; as brightness increases the blue and red components become slightly lacking, so whites can at times take on a marginally warmer, faintly greenish tint. These are not faults that immediately catch the eye when watching a film. Average error values hover around 3, so the factory setting can be regarded as quite good. The situation is similar in HDR. Here too there is a slight lack of the blue component, so the image is marginally warmer than the reference, but the difference is not large enough to significantly interfere with normal viewing.

After calibrating the TCL C75B, it has clearly improved in terms of colour reproduction. Although the television does not offer many options for adjusting the white balance, we managed to enhance its settings quite significantly. As a result, the image is no longer excessively pink, and the colours now look much more natural and harmonious.

The gamma jump, which was previously an issue, has not completely disappeared, but we have managed to reduce it considerably. This has made details in dark scenes more visible – both in HD and 4K HDR materials.

Unfortunately, the lack of local dimming is still noticeable. The "blooming black" effect remains, but that is a limitation of the display itself. Nevertheless, the colours after calibration look far better, and the image is much more enjoyable to watch.

After calibration, there is particularly a lot to be gained from SDR content. The white balance was set almost perfectly, the gamma practically matches the reference value, and the average colour errors fell from around 3 to about 1. That is already a level at which differences from the reference image are, in practice, very difficult to detect. The Bravia 3 II therefore shows that, despite its position in Sony’s lineup, it has quite a lot of potential for precise picture calibration. Improvements are also visible in HDR, although here it is no longer possible to avoid all the limitations of the TV itself. After evening out the colours, it is easier to notice that the EOTF curve in film content runs slightly below the reference value in places, so the Bravia 3 II gently darkens part of the image. This is not an ideal solution from a reference point of view, but in this particular TV it also has its benefits. With no local dimming and average black levels, this behaviour slightly reduces the visibility of the backlight in darker scenes and helps maintain a stronger impression of contrast. So you could say Sony partly masks the limitations of the panel this way, instead of trying at all costs to stick to the reference luminance.

TCL C75B has a tone transition smoothing function, but unfortunately, we cannot commend it. Regardless of the selected level – low or high – tone transitions in older materials remained visible, as if the function wasn't working at all. It's hard to say anything positive about it, as in practice it seems completely useless.

The image scaling is better. The television performs quite decently, although on thinner elements, like branches in the background, you can notice slight jaggedness. However, this is not something that significantly interferes with daily viewing.

Unfortunately, a bigger problem turned out to be overscan, which is cutting off the edges of the image. In our tests, there were instances where news tickers or other elements near the edge of the screen were cut off. This is definitely something to pay attention to, especially if we use the television for watching news programmes or content with text on the screen.

The Bravia 3 II is Sony's first TV to use the new MediaTek Pentonic 800 chipset, and there are a few changes in image processing. Starting with the basics. The upscaling itself is adequate. The TV can sensibly pull up lower-resolution material and does not have a strong tendency to over-emphasise jagged edges or other source imperfections. With regular broadcast TV or weaker streaming material the picture therefore remains quite pleasing. We have more reservations about the digital image processing. In this model Sony has replaced the well-known "Smooth Gradation" function with a new setting called "Digital Noise Reduction". Its role is essentially very similar: it is supposed to smooth unpleasant tonal transitions and artefacts resulting from heavy signal compression. Unfortunately, this function performs noticeably worse than before. At the "High" setting (the only one that had any visible effect) the TV can smooth away too many elements of the image at once, causing film grain to disappear and the texture of objects or even skin to start looking unnatural. Worse still, the effect is not particularly stable. When a scene contains more motion, the function's effect clearly weakens and at times it looks as if the TV stops intervening in the picture altogether. For everyday viewing we therefore would not recommend using it at a high level. It can help on a static shot, but the price is often an excessive loss of detail.

The TCL C75B definitely has something to offer gamers. The television is equipped with a panel that can display images with a refresh rate of 144 Hz in 4K, and even 240 Hz in Full HD. These are really impressive results, especially for a model from the entry-level range.

In addition, there are features for improving fluidity and reducing motion blur in films. The "Motion" option allows precise adjustment of the effect on a 10-point scale, which offers great personalisation possibilities - everyone can set the fluidity as they like.

Motion handling is definitely one of the Bravia 3 II's strongest points. The TV uses a 120Hz VA panel, a solution that, by nature, despite the high refresh rate, does not always cope well with motion blur. Here, however, Sony has managed to keep that problem very well under control. Fast-moving objects remain crisp, and the characteristic trails and blurring are reduced to a very low level, if not to zero. It is one of the least motion-blur-prone LCD TVs we have tested. Interestingly, in this respect the Bravia 3 II can even outperform the much more expensive True RGB flagship series, the Bravia 9 II.

The TCL C75B is undoubtedly a television designed with gamers in mind. It offers nearly everything that even the most demanding console users could need. With the implementation of fully capable HDMI 2.1, the television supports features like ALLM (Automatic Low Latency Mode) and VRR (Variable Refresh Rate) – operating within the full potential of the television, up to 240 Hz in Full HD resolution.

Additionally, the television supports advanced HDR technologies, including Dolby Vision and HGiG, allowing for even better detail reproduction in HDR-optimised games. The C75B is also equipped with a very convenient interface for gamers in the form of Game Bar, where all key parameters such as refresh rate, input lag, and image settings can be checked – all within a single click.

In a nutshell: the C75B is a great choice for gamers, offering a wide range of features that allow users to fully enjoy the capabilities of modern consoles and games.

Sony Bravia 3 II is a very good TV for gamers, although not everything has been implemented exactly as we would like. The biggest change concerns the connectors. For the first time in a Sony TV we get as many as four full HDMI 2.1 ports with 48 Gb/s bandwidth, thanks to the new MediaTek Pentonic 800 chipset. That removes one of the issues that has plagued this manufacturer’s TVs for years. We can connect several devices at once and on each input use the device’s full capabilities, for example VRR or ALLM. There is also a simple Game Bar that lets you view key signal parameters and change a few useful settings, such as black level, when you want to improve visibility in darker parts of a game. However, there are two limitations worth knowing. The first is the lack of support for 1440p at 120 Hz. That will not be a problem for everyone, but people using that resolution on a console or PC, for example to get higher frame rates in certain games, will have to choose 1080p. We have more reservations about HGiG support. Sony does not allow you to disable the TV’s tone mapping on the Bravia 3 II, so the screen is always processing HDR content even when you would prefer to leave that task to the console. This is most obvious during HDR setup — the checkerboard pattern does not disappear at the point that corresponds to the TV’s actual capabilities. That does not mean HDR in games will look bad. You just need to approach the setup a little differently and, instead of relying on the pattern, manually set the peak brightness to around 450 nits. The issue can be worked around, but you should know about it before you start setting up the console.
