Sony X90L vs Panasonic Z95A

HDR on the Sony X90L TV looks promising. The luminance chart showed that the television has a solid power reserve, reaching a maximum of 1000 nits in synthetic tests. However, how does this perform in real-world scenarios? In scenes such as the opening of Life of Pi or the final sequence from The Meg, the TV is able to deliver this power on HDR content, reaching about 800 nits. Unfortunately, displaying small light elements on a black background, as seen in the scene from Sicario 2, poses greater challenges for the X90L – here the results drop to around 600 nits. Despite this, when compared to competing models with mini-LED technology, the effect looks very good and can shine just enough to impress us. Notably, the colour gamut coverage is commendable, with a score of 96% for DCI-P3 and 76% for BT.2020, indicating good colour reproduction in HDR content.

Panasonic Z95A showcases class when it comes to HDR performance. In luminance tests, it achieves a level of 1800 nits, which has a real impact on movie watching. Scenes from Life of Pi or Gemini Man look fantastic – the television effortlessly renders details and intensity of bright spots, impressing with its power. In more demanding moments, like the final scene from The Meg, one can see how bright light floods the screen. In such moments, brightness drops, which is typical for organic matrices. Nevertheless, a result around 1000 nits can still be considered excellent, still providing very good image quality. Additionally, the television offers excellent coverage of wide colour palettes – as much as 98.6% for DCI-P3 and 74.5% for BT.2020. Thanks to this, colours are not only vivid but also deeply saturated, allowing for a full appreciation of the richness of details, especially in HDR scenes. Such coverage makes the hues look more realistic, and the HDR effect gains in intensity and accuracy. All this impressive HDR effect is thanks to MLA technology, which enables achieving such high luminance and excellent image detail. Because of this, the Panasonic Z95A offers HDR at a level that truly makes a difference.

The best mode in Sony televisions is the IMAX Enhanced mode. Although IMAX is mainly associated with the cinematic experience, here the colour reproduction out of the box is average. In the case of lower quality content, such as HD – regular television or YouTube – it is worth paying attention to the white balance. It is characterised by a deficiency in red and an excessive dominance of blue, which gives the image a pinkish hue. The brightness characteristic, or gamma, for HD content is quite decent, but a slight boost could make the image appear washed out and look as if it is behind a light fog.

In 4K HDR content, the situation looks somewhat different. The white balance shows a significant boost in blue, which causes the image to become unnaturally sharp and seem artificial. Such an exaggeration in colour reproduction may not appeal to everyone, especially if one prefers more realistic shades. Additionally, the EOTF curve in Sony X90L appears quite correct at first glance. However, at the end of the graph, some fluctuations can be seen, suggesting that the television is trying to maintain appropriate brightness to avoid overexposing larger elements.

The best picture mode on the Panasonic Z95A is undoubtedly the Filmmaker mode. It offers quite a good image reproduction, but it is not free from certain issues that require improvement. Firstly, the white balance, for both 4K and HD content, tends to have a dominance of red and blue hues. This causes a slight pinkish tint to the image, particularly noticeable in bright, white scenes. Such deviations can be seen in the comparative photo below, which illustrates this issue well. The Colour Checker test also confirms these discrepancies, showing slight shifts in the dots towards the mentioned shades.

In terms of gamma brightness characteristics, it performs very well, with only minor problems when brightening small details. A greater challenge is posed by the EOTF curve, which is responsible for controlling brightness in 4K HDR content. Here, there is a slight boost in brightness above the reference value, which sometimes makes the image too bright, especially in more demanding scenes. Although the Filmmaker mode is definitely the best choice on the Z95A, these aspects require refinement to fully utilise the television's potential.

Sony offers a range of tools for improving image quality, including two additional picture modes that we decided to utilise during testing and to apply calibration to. This solution significantly facilitates the calibration process and is very effective, provided the appropriate tools are available. In the case of HD content, the white balance was almost perfectly aligned – only one shade of grey exceeds the error value of "1", which is an excellent result. The same can be said for the brightness characteristic (gamma), which presents itself nearly perfectly, with microscopic deviations on the order of 0.01.

In the case of 4K HDR content, the situation is not quite so ideal. Although the white balance has been greatly improved, it has not been possible to completely eliminate the dominance of blue colour. Nevertheless, the errors on the Colour Checker test only occasionally exceed the value of "2", which means that image distortions are practically imperceptible. As for the EOTF curve, it is worth activating the filter in the top right corner "EOTF in Films" – the graph looks correct, but the television encounters difficulties when illuminating very small elements, which is due to the limited number of dimming zones. Despite these minor errors, it is thanks to the calibration that the IMAX Enhanced mode on the Sony X90L makes watching films feel like a true cinema experience.

After calibration, Panasonic Z95A shows its full potential, offering an almost perfect picture. The television provides immense adjustment capabilities, which we have fully utilised. The white balance after calibration is positively perfect, and errors in SDR content at the level of 0.5 place it in an absolutely reference standard. The same is true for 4K HDR content – the screen tint has been completely eliminated, and the white balance is now exemplary.

The colour palette and Colour Checker test confirm the excellence of the calibration. Errors below 2 are a result that will satisfy both professional calibrators and enthusiasts of cinematic picture quality. Significant changes have also occurred in the brightness characteristic – the EOTF curve has been flattened, eliminating previous issues with excessive brightness. And a small gamma error has been reduced.

Before calibration, the picture was decent, but now it's an entirely different league. It's a real feast for the eyes, the quality of which is hard to compare to anything else. Panasonic Z95A, after fine-tuning the settings, becomes a true master of colour reproduction.

The Sony X90L television features a tone transition smoothing function known as Soft Gradation, which is extremely effective. Even at the "low" option, the effects are satisfactory, but at the "medium" setting, it works like a dream – we recommend using this option for the best results. The image scaling on the Sony X90L is simply excellent. The image is not overly sharpened, which provides a natural effect and ensures that everything looks cohesive. It's clear that the engineers really focused on this aspect, creating a solution that is impressive and performs well in daily use. Because of this, even when watching content such as regular television or YouTube, where the image is not inherently stunning, one can enjoy a smooth, cohesive, and visually pleasing experience.

In the case of lower quality materials, the function "Gradation Smoothing" is responsible for smoothing tonal transitions. The best results are achieved with an intermediate setting – although they are not spectacular, the function works correctly and does not introduce unwanted effects into the image. It can be rated as average, but sufficient to improve the quality of tonal transitions.

As for digital processing, or upscaling, the image looks surprisingly good. It is vivid and pleasant to the eye, which makes lower quality content, such as standard television or YouTube, look quite decent. However, minor issues can be noted, such as "jagged" edges, for example, branches in the background. Nevertheless, this does not significantly affect the overall viewing experience, and the television handles these materials in an acceptable manner.

Sony X90L with a 120 Hz panel is an excellent choice for both gamers and cinema enthusiasts. The television is equipped with the Motion Flow smoothing feature, which allows for adjusting motion fluidity using two sliders: "smoothness" and "clarity." The "smoothness" slider controls the level of fluidity in motion, which helps reduce image stuttering, while "clarity" is used to minimize blur and enhance motion sharpness, which is particularly useful in dynamic scenes.

Panasonic Z95A, thanks to its 144 Hz panel, offers excellent image fluidity. For films, there is an "Intelligent Frame Creation" feature that enhances fluidity and reduces motion blur. The user has two sliders at their disposal: "Motion Blur Reduction" – responsible for clearer and sharper details in rapidly moving scenes. "Film Smoothness" – adds fluidity by creating additional frames between the originals, making motion appear smoother and more natural with a "soap opera" effect.

Thanks to this, viewers can adjust the settings to their own preferences. Films and less dynamic material look smooth and natural, which should satisfy most users.

Sony X90L is a television that performs well in terms of compatibility with consoles and features for gamers. Its 120 Hz panel and two HDMI 2.1 ports with a bandwidth of 48 Gb/s allow for smooth playback of high-resolution games at a high frame rate. Gamers can also take advantage of the ALLM feature, which automatically switches the television to low latency mode, and VRR, which ensures smooth gameplay without image stuttering. The Game Bar is an additional advantage – an intuitive tool that provides quick access to the most important gaming settings and features, facilitating control over gameplay.

Unfortunately, when it comes to HDR in games, the Sony X90L has its limitations. There is a lack of support for HGiG, a standard that many gamers consider crucial for precise HDR reproduction in games. While the television supports Dolby Vision, which could theoretically improve image quality in games, the practical application of this feature is problematic. Dolby Vision in game mode is associated with very high input lag, making gameplay less comfortable and precise movements more difficult. Additionally, it is not possible to enable Dolby Vision alongside VRR. This means that despite its numerous advantages, gamers seeking the ideal HDR in games may feel a sense of disappointment.

Panasonic Z95A this year shows that the manufacturer has made a huge leap forward in terms of support for gamers. The television offers virtually everything one could expect from a device in this bracket. Support for ALLM (automatic low latency mode) and VRR (variable refresh rate) ensures smoothness and eliminates tearing in dynamic games. The 144 Hz panel allows for incredible fluidity, and additional support for resolutions other than 4K provides greater flexibility, which is a significant advantage for gamers using various configurations.

A unique and quite specific feature is the "Game Bar." Its ball-shaped interface stands out from the competition and allows for quick adjustments of key settings such as VRR, brightness level, or picture mode, without having to interrupt gameplay.

However, in this class of device, there is a minor disappointment – the Panasonic Z95A offers only two HDMI 2.1 ports, instead of four. This is definitely too few for a premium television, especially at a time when many people own more than one device requiring full HDMI 2.1 support, such as a next-gen console or an advanced computer. In this category, it's hard to accept this limitation, especially given the high aspirations of this model. Nevertheless, the television is an excellent choice for gamers, offering versatility and functionality at the highest level.
