Sony X90L vs Haier M90E

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.

Haier M90E is a television that does not lack brightness. In most film scenes, the peak luminance exceeds 1000 nits, which gives the image a distinct 'kick' and high dynamics. It performs really well in typical bright HDR materials. However, one must take into account the aforementioned dimming algorithm. In scenes that are not uniformly bathed in light – for example, when displaying single stars on a black sky – the high brightness highlights imperfections in zone control. Instead of a precise point of light, we often see a pronounced halo effect around bright objects. Despite these shortcomings, the overall image presentation can be pleasing, largely due to the colour reproduction. The manufacturer used a phosphor PFS coating, which allows for a wide coverage of the colour palette. In our measurements, the coverage of the DCI-P3 space reached a solid 95%.

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.

For the measurements, we selected the Film mode, which is supposed to offer an image closest to the creators' intentions. Unfortunately, in the case of the M90E, its characteristics – apart from the reduced brightness – differ little from the Dynamic mode. Both in SDR and HDR materials, the image is distinctly tinged with a cool blue hue. The white balance is heavily skewed towards blue, which resembles typical, aggressive 'store' settings. This results in an unnatural representation of skin tones and makes the image fatiguing to the eyes over extended viewing periods. The management of brightness also negatively impacts colour fidelity. The television struggles to maintain proper levels – small details are often too dim, while larger, bright areas of the image suffer from clipping. These deviations in the brightness curve, combined with the cool white balance, lead to very significant colour reproduction errors (DeltaE) in the factory settings.

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.

Haier M90E clearly benefits from professional calibration, particularly with SDR content. The television's menu offers a sufficient number of tools to effectively correct factory errors. We managed to 'tame' the white balance and eliminate the dominant blue tint. We also corrected, though to a lesser extent, the brightness curve (gamma), which allowed us to recover some detail in the shadows that were too heavily dimmed out of the box. The final effect in SDR is a picture that is significantly more natural and pleasant to watch. In HDR mode, the success is only partial. Although we were able to improve the white balance here as well, colour reproduction errors (Color Checker) remained at a high level. Analysis of the EOTF curve (responsible for brightness in HDR) indicates the cause of the problem: the television imposes its own interpretation of the signal and does not provide tools for modifying this curve. The source of the high errors is not the calibration itself, but the specific characteristics of the device – aggressive and imprecise zone dimming interferes with measurements and is 'firmly' embedded in the characteristics of this model.

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.

The evaluation of the image processor must be divided into two separate aspects, as the Haier M90E behaves inconsistently here. The first issue is the upscaling itself, that is, scaling lower resolution content to 4K. In this task, the television performs quite decently. The algorithms effectively enhance detail, resulting in a relatively sharp, clear, and legible final image. In this regard, it is hard to have major objections to the device.

The situation is completely different with materials that have a high degree of compression, as encountered in older recordings or on platforms like YouTube with lower bitrate. Here, the processor "struggles" with smoothing tonal transitions and masking imperfections in the source. The television fails to hide compression blocks, resulting in a very harsh, "digital" character of the image. The lack of effective artifact reduction can severely discourage viewing lower quality content on this screen.

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.

The Haier M90E is equipped with a simple yet functional motion smoothing system (MEMC). In the settings menu, the user will find a three-level adjustment scale: low, medium, and high. This allows for the adjustment of the degree of intervention in the image to one’s own preferences – from gentle smoothing of 24p films to maximum fluidity (the soap opera effect). The system operates stably and fulfills its purpose in typical applications.

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.

From a hardware perspective, the Haier M90E is a solid proposition. The television is equipped with two full-bandwidth HDMI 2.1 ports, which supports key technologies: VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). It is also worth noting the proper implementation of the Dolby Vision mode for gaming, which maintains a relatively low input lag. Problems arise with the software configuration. The biggest drawback is the forced, continuous dynamic tone mapping by the television’s processor. This prevents correct HDR calibration from the console using system test patterns (HGiG) – the television ignores source settings and processes the image on its own terms. We also noted shortcomings in the interface: the M90E does not have a typical "Game Bar" (overlay with parameters), which is standard among competitors. Collaboration with Xbox consoles proved problematic with unusual parameters – the device struggles to correctly display a resolution of 1440p at a refresh rate of 120 Hz. Despite the aforementioned software shortcomings, the Haier M90E remains a very appealing screen for gamers. The overall reception is saved by the solid hardware base. The native refresh rate of 144 Hz and the presence of full-fledged HDMI 2.1 ports are advantages that are crucial for everyday use. If we are looking for a television that ensures high fluidity and supports 4K signal, this model will fulfil its task.
