Sony X75WL vs Panasonic W85

The luminosity chart for the X75WL Sony television showed a maximum value of 350 nits, which is unfortunately not an impressive result. The television does not surprise with its brightness, and all the HDR scenes we tested lacked depth and the appropriate light effect that should accompany HDR content. Additionally, the poor coverage of the DCI-P3 colour gamut makes it difficult for the television to reproduce rich colours, which significantly affects the overall viewing experience of HDR content. The lack of adequate brightness and weak colour coverage mean that HDR effects are very limited in 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.

Colour reproduction tests for the model Sony X75WL are carried out in movie mode, which offers the best image settings, but it also has its flaws. The biggest problem with the X75WL Sony is the white balance – for both HD and 4K HDR content – which is characterised by a dominance of blue. As a result, the entire image feels too cold. The colour checker confirms these errors, showing that the colours lean towards cooler tones. In terms of brightness characteristics, the contrast gamma is at a fairly decent level, however, the same cannot be said for the EOTF curve. There are significant issues with maintaining appropriate brightness – the image is either overly bright or too dim, which impacts the visual perception of content.

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.

X75WL Sony is one of those cases where image calibration may not be highly spectacular, but it offers a very good improvement in the perception of colours. The white balance, for both HD and 4K materials, has been significantly improved – there is no longer a strong dominance of cooler shades. The gamma curve also appears more stable, which translates into better image quality. However, the biggest issue remains the EOTF curve, which is responsible for brightness in 4K materials. Due to the technological limitations of the television (IPS panel and lack of local dimming technology), it is hard to speak of a significant improvement, as we cannot extract more from this model. Despite these limitations, the tonal quality of the image has been significantly enhanced.

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.

In the case of low-quality tonal transitions, the television Sony X75WL performs poorly. The lack of any feature to improve tonal transitions results in noticeable imperfections in colour gradation. However, one can credit the quite good digital processing – the image is displayed without overscan, and overall it looks relatively good thanks to the added slight sharpness, which some users may appreciate.

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 X75WL Sony television is equipped with a 60 Hz panel, making it more suitable for watching films than for dynamic gaming. This model features a motion smoothing function called Motionflow, which allows the user to adjust the picture on a 10-point scale. Smoothness is responsible for adding intermediate frames, thereby increasing the fluidity of motion, while the image becomes more theatrical, minimising the cutting effect. Clarity reduces motion blur, which is particularly useful in fast scenes such as sports or dynamic actions in films. With this feature, users can adjust the fluidity and sharpness of motion to their own preferences.

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.

X75WL is not the best television for gamers. It only has the ALLM (Auto Low Latency Mode) feature and a basic Game Bar, which are not enough to satisfy more demanding users. In this price range, one could expect support for features like VRR or 120 Hz refresh rates - although in FULLHD, which are already standard - unfortunately, they are lacking here. This is a major downside for Sony, as the competition offers much more for gamers in a similar budget.

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.
