Philips PUS8359 (VA) vs Sony X75WL

Philips PUS8359 did not impress us with its results in HDR materials. This model is capable of generating a maximum brightness of 320 nits, and often even less. Such results, combined with a lack of support for HDR Dolby Vision, mean that the image will be significantly darker compared to the source material. Therefore, playing SDR materials will be more beneficial for this television. This is also suggested by the rather low coverage of the DCI-P3 colour gamut at 83%, which results in significant colour deficiencies. The fact remains that the television supports the HDR format based on dynamic metadata, although HDR10+ is such a niche format that it does not bring any significant advantages.

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.

The best factory mode in terms of fidelity to the source material was "Film". This was the mode we used during our tests. Just like each of the factory modes in televisions, it had its shortcomings. We will check what exactly was wrong in both SDR and HDR materials. In both cases, the white balance showed excessive dominance of the green and red colour combination. This created a yellow tint that spread across the entire image, causing issues such as yellowed whites and problems with skin tones. This situation was perfectly illustrated on the "ColourChecker" palette, where each of the tested samples was pushed into its warmer counterparts. The foundation of the image is primarily contrast and black. These are represented by gamma charts and the EOTF curve. Looking at the first one, we can see a true rollercoaster, as we can observe both an elevated and a lowered gamma. The heavily elevated gamma caused visibility issues in blacks, while the lowered gamma led to a dramatic drop in contrast. In this context, the EOTF curve performed significantly better, only slightly brightening the image.

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.

Philips offers a wide range of image calibration tools in both its more expensive and cheaper models. We utilised these tools and got to work, which was not as easy as many of you might think. While we were able to model the white balance, significantly improve the gamma, and refine the EOTF curve in both cases, the deltaE errors remained extremely high. There are several reasons for this situation, which are directly related to the low coverage of the DCI-P3 palette and the maximum brightness of the unit in HDR materials.

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.

In this paragraph, we will take a look at two functionalities. We will once again examine the feature responsible for tonal transitions, but we will also check how the television performs with image scaling. The option responsible for smooth gradation is called "Distortion Reduction". As we have established, it quite effectively smooths out the inconsistencies. However, we must point out two things: we cannot enable it for HDR materials and that it blurs details in films.

The tested television cannot boast of the best image scaling. There is a noticeable overall blurriness of the image, but worse still, it blurs details. This is particularly evident on the branches and the model's hair. A characteristic white halo around the character is also visible.

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.

Philips PUS8359 will not be the best television for sports. The reason for this is the lack of implementation of even the basic motion smoothing feature, which was to be expected given the price of the device. We also note that we are dealing with a VA panel, whose sharpness is not of the highest standard. This type of panel is mainly associated with high contrast, which goes hand in hand with quite a slow response time, as clearly indicated by the matrix analysis results. As you can see from the images captured in rapid motion, the picture is typically blurred for this type of panel. Although it may not be the ideal option, it can be used conditionally for watching sports; however, one must keep in mind the less than optimal sharpness in motion. It is worth mentioning that films will exhibit judder, as the television does not have any motion smoother, even the simplest one.

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.

It will not be a surprise if we write that Philips PUS8359/12 only offers the most basic support for consoles. Once the console is connected, we can count on features such as: VRR and ALLM. This is quite pleasing in the case of the former, as experience has shown that even in more expensive units there can be issues with this. A nice touch is the implementation of a special GameBar that allows for changing settings on the "fly," so we won't have to exit the game and unnecessarily distract ourselves. This feature also allows for adapting gameplay to the needs of people with disabilities, which will certainly be extremely useful.

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.
