TCL C75B vs Panasonic W85

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.

Unfortunately, we do not have good news here. The Panasonic W85B is rather dim – its peak brightness does not exceed 300 nits, so it’s hard to talk about any true HDR effect. In practice, this means that scenes which can “shine” and make an impression on other screens simply look like ordinary SDR with a slight boost in colours here. Our measurements and film tests confirmed this – regardless of the content, the W85B will not extract anything more from HDR. Therefore, if someone is looking for a television specifically for HDR, it is better to look towards other models. As consolation, the fact remains that in terms of colours, the W85B performs quite well. It is a QLED television, so its colour gamut coverage is wide, and most films and series look natural, without a distinct “washed-out” effect. The colours are saturated, so in everyday viewing, there is no sense that something is strongly amiss.

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.

When testing the Panasonic W85B, we obviously started with Filmmaker mode, as this is today’s gold standard when it comes to watching content “as the director intended.” The problem is that this television is quite far from those intentions. The biggest issue turned out to be an excess of red – both in SDR and HDR. The image often appeared too warm because of this, and in some scenes, it was almost “blazing.” Additionally, there is the issue of brightness management. When we looked at the gamma or EOTF charts, it was clear as day that in most scenes, the television brightens the image more than it should. The effect was simply predictable. Details can get lost, there is flattening, and highlights are blown out across the entire screen. We know, of course, how to correct this, but it must be said honestly that it requires a lot of work during calibration. Out of the box, the W85B does not provide a picture close to reference – it is rather a television that will always interpret colours and brightness a little “in its own way” without professional adjustments. Unfortunately, this is to the viewer’s detriment.

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.

Fortunately, calibration made a significant difference for the Panasonic W85B, particularly in SDR content. Here, the improvement was really noticeable – we managed to balance the whites and somewhat tame the tendency of the television to excessively brighten the entire image. The picture became more coherent, and the colours gained a naturalness that was lacking in the factory settings. Admittedly, the results from the Color Checker are not perfect, as the W85B has visible issues with green saturation, but overall, we evaluate the post-calibration effect in SDR very positively. The situation is a bit different with HDR. Here too, we managed to reduce the tendency to warm up the entire scene, so the image performed significantly better than in the factory settings. However, the same issue we mentioned earlier is still evident – the television interprets the image too much "on its own" and brightens the entire screen. The lack of local dimming only exacerbates this effect. In summary, briefly in SDR content, the W85B performs really well after calibration and is more than suitable for daily viewing. However, in HDR, even after adjustments, it remains difficult to unequivocally recommend it for serious viewing sessions.

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.

With native SDR content, the Panasonic W85B performs very well – tonal transitions are smooth and natural, without artificial bands or prominent contours. However, the situation is worse when it comes to lower resolution materials. It is precisely there that the television has the most difficulty with "enhancing" the image. The lack of any option in the menu that would allow for improving gradation means that with older films or materials from YouTube, one can sometimes notice slight issues with colour blending.

Fortunately, upscaling, or raising the quality of lower resolution content, performs much better. This is definitely a strong point of this model – the image is scaled cleanly and in detail, and the television handles this better than one might expect from such an inexpensive piece of equipment. This is thanks to the HCX processor, which Panasonic has been developing for years, and it is noticeable that even in the lower series it can do a good job.

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.

At first glance, everything looks good – the Panasonic W85B has a 120 Hz panel and even a 144 Hz mode, so it seems that it should cope well with smooth motion. The problem arises when we look into the settings. The options for improving fluidity are supposedly present in the menu, but in practice… they don't change anything. No matter what we choose, the image looks the same. On top of that, there is a lack of BFI, or the black frame insertion mode, which on many televisions helps sharpen motion. And suddenly it turns out that despite the strong panel, the W85B offers us no real tools to adjust motion according to our needs. It’s only good when the source itself operates at a higher frequency – for example, games at 120 Hz. But when it comes to films or sports, we simply have to accept what the television shows us, because nothing more can be done about it.

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.

On paper, the Panasonic W85B looks really solid. It has two full HDMI 2.1 ports, support for ALLM, variable refresh rates, Dolby Vision in games, and of course, a high refresh rate of the panel itself. Additionally, it features Panasonic's characteristic game tools bar – a "game bar" that allows you to preview key parameters and quickly change them if needed with a single click. This sounds great, but the problem arises when we turn on HDR. Here, the W85B suffers significantly, as there is practically no HGiG implementation – the television poorly manages brightness, and instead of an accurate picture, we get scenes that are too bright, sometimes even blown out. The solution? The simplest one – turn off HDR in the console settings and leave everything in SDR. And this is where it gets really interesting, as in this scenario, the W85B shows its better side. Low input lag, high fluidity thanks to 120 Hz – all of this makes gaming look phenomenal. Indeed, HDR can be forgone, but if the priority is responsiveness and smooth gameplay, the W85B offers a lot of fun.
