Sony X90L vs Samsung Neo QLED QN70F / QN74F / QN77F

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.

The QN70F is a television that can pleasantly surprise when it comes to brightness. In ideal testing conditions, it reaches up to 800 nits, which – for this price range – is a really solid figure. Of course, this result comes from measurement charts, so we decided to check how it performs in practice, with real films. Here, the television somewhat tempers its capabilities. In most tested scenes – for example, in "The Meg" – the actual HDR brightness hovered around 500 nits. This is still a decent result, allowing for enjoyment of HDR effects, although it is far from perfect. On the other hand, we have a QLED screen with a layer of quantum dots, which means very good colour reproduction capabilities. The colours are vibrant and saturated. The QN70F covers about 94% of the DCI-P3 colour space, and in the wider BT.2020 palette, it exceeds 75%, so in this respect, there is nothing to be ashamed of.

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.

We tested the QN70F in its best default picture mode, which is Filmmaker Mode. I must admit that in this particular test unit, the factory settings performed quite well. The image was calm, natural, and despite minor deviations – pleasant to watch. The biggest flaw was a slight dominance of red in the white balance, which caused a slight pinkish hue across the entire scene. However, this was not a glaring defect – rather subtle and only noticeable when directly compared to a properly calibrated screen. A somewhat larger issue arose in the brightness characteristic. The television tends to underestimate the brightness of parts of the image that should be displayed more brightly. As a result, some details can appear slightly muted – not so much lost completely, but not resonating as clearly as they should. Nonetheless, as far as televisions in this category and in these settings are concerned – we consider the result a good starting point for further calibration.

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, the QN70F shows that it can offer a truly high level of colour reproduction. The white balance was nearly perfectly aligned, and the values in the Color Checker test dropped below level 3 – meaning below the threshold at which the average eye can perceive differences. The image looks natural, and the colours are faithfully rendered, without excessive saturation or the coolness known from factory settings. It must be admitted that Samsung provides very extensive calibration options – not only for enthusiasts but also for professionals. The QN70F takes advantage of this potential and, after proper adjustment, can come close to significantly more expensive models in terms of colour accuracy. The only thing that can still be nitpicked is the brightness characteristic. There is still a tendency to lighten the smallest areas of the image – particularly those that should remain darker. However, this is a design feature of this model, not a calibration error. Despite this, the final effect definitely deserves recognition.

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.

Samsung QN70F offers a distortion reduction feature that enhances the smoothness of tonal transitions. In "Standard" mode, it works quite well – it smooths out problematic transitions without significantly interfering with the structure of the image. Film grain is somewhat reduced, but details such as texture and skin structure remain visible. The "High" mode is much more aggressive. The smoothing is stronger, but it comes at the cost of a noticeable loss of detail. Therefore, in practice, we recommend sticking with the "Standard" setting or completely turning this function off. The improvement in gradation may be less spectacular, but the image retains more naturalness.

When it comes to scaling low-quality content, the QN70F performs very well. Tests with lower resolution images were really very good. Despite slight edge ringing, everything looks clean and clear, even if the original content was very poor. It’s just a pity that the television has an issue with overscan, which cannot be completely turned off. As a result, images with very low resolution may be slightly cropped, which is mainly noticeable on subtitles or interfaces.

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 QN70F is a television with a refresh rate of 144 Hz, which in itself places it among the top when it comes to image fluidity. Whether we are watching dynamic sports broadcasts or playing on a console – the picture looks very good. There is no sense of stuttering, choppiness, or the typical "tearing" associated with weaker models during fast motion. Samsung also allows you to adjust the fluidity to your own preferences. In the picture clarity settings, we find options such as blur reduction and judder reduction – each of which we can adjust independently. This is especially useful when watching content with a lower frame rate and wanting to give it a smoother, more theatrical character – or conversely, to maintain the natural cinematic "feel" of 24 frames.

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.

The Samsung QN70F is truly a solid choice for gamers. Here, we find as many as four HDMI 2.1 ports with full bandwidth of 48 Gbps, meaning full support for gaming in 4K at a refresh rate of 144 Hz. Additionally, it includes all the essential features we expect today: automatic game mode (ALLM), variable refresh rate (VRR), and a very well-designed, intuitive Game Bar showing information about mode, resolution, and frame rate.

Also noteworthy is the Game Motion Plus feature, which allows artificial frames to be added to games running at 60 fps or less. This works surprisingly well and in many titles – particularly those where consoles struggle to maintain a stable framerate – it improves the fluidity of gameplay without significant delay.

Unfortunately, there are some drawbacks. The lack of support for Dolby Vision mode is not surprising – it’s a standard with Samsung. However, the absence of the HGiG feature is much more disappointing. Worse still, it was removed with a software update, which may leave users who previously relied on it quite puzzled. Without HGiG, it is impossible to manually set the maximum HDR brightness from the console, resulting in some games appearing slightly washed out – especially if the television misinterprets the tonal range. Why Samsung, a brand that has set standards for gaming features for years, decided to take such a step is hard to say. At the time of writing this review, the tested television was running on software version 1110 – and frankly, if you care about full support for gamers, it’s better to hold off on updates for the time being.
