Samsung DU8002 (IPS) vs Sony X90L

The HDR effect on the DU8002 television leaves much to be desired. A brightness level of 300 nits cannot provide a true high dynamic range experience, which makes the viewed content resemble more of a standard SDR than impressive HDR. Scenes that should dazzle with brilliance and detail appear muted and lacking in depth. Nevertheless, the television deserves praise for its high coverage of the DCI-P3 colour gamut at 92%. This means that colours are vivid and saturated, which may satisfy viewers who prefer rich tones, even if the HDR effect does not fully meet expectations.

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 DU8002 offers a Filmmaker mode, which is intended to provide an authentic image reproduction in line with the creators' vision. Unfortunately, despite the promising name, the results are far from ideal. The white balance in this mode shows significant drops in blue, leading to a noticeable yellowing of the image, as seen in our comparison photo. Colour Checker tests confirm these errors. As for brightness, the gamma characteristic is too low compared to the reference line of 2.4, resulting in excessive screen brightness. A similar issue occurs with 4K content – the EOTF responsible for brightness in 4K material shows significant increases above the reference line, leading to excessively bright small light elements. As a result, the Filmmaker mode in the DU8002 does not meet expectations and instead of offering high quality, presents an image full of tonal and colour inaccuracies.

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.

Samsung is one of those companies that offers advanced tools for improving picture quality in its televisions, including a 20-point white balance adjustment. Even in the budget model DU8002, with the right adjustments, surprisingly good results can be achieved. The white balance, especially for HD content, is really good – tests on the Colour Checker palette confirm accuracy levels of 2–1.5, which speaks to this television's considerable capabilities in colour reproduction. In 4K content, although not as perfect as in lower quality materials, the overall picture looks significantly better.

The gamma brightness has also been heavily adjusted, meaning the picture is not overly bright and looks more natural. What about the EOTF curve? At first glance, it seems fine, but upon closer inspection, especially in film tests, it is clear that the television, due to its low contrast matrix, struggles. The EOTF also drops below the reference line. Nevertheless, the DU8002 is an example of a budget model where calibration is worth investing in. Although construction flaws, such as the type of backlighting, cannot be completely eliminated, colour accuracy is surprisingly good, especially given its price.

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.

Smoothing tonal transitions on the DU8002 television leaves a mixed impression. Although the menu features an option for smoothing tonal transitions, in practice it yields no results and may even generate unwanted side effects.

Nevertheless, the television performs excellently with upscaling, or digital image processing. The test pattern with the model looked really good – the image is not excessively jagged, and the overall presentation is decent and pleasant to the eye. This is definitely good news for those planning to watch traditional television on 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 DU8002 with a 60 Hz panel is a television that performs better for watching films than for intense gaming. The motion smoothing feature acts as a fluidizer, smoothing out movement and giving scenes a more fluid appearance, which is helpful for movie screenings. In the context of gaming, this model is more suited for casual entertainment.

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.

DU8002 is a television that is primarily suitable for casual gamers. The 60 Hz panel does not provide the highest motion smoothness, so in dynamic games, there may be a lack of that extra fluidity in the picture. On the plus side, it features ALLM and HGiG functions, which automatically adjust the picture settings for HDR gaming, enhancing the gaming experience. Unfortunately, the television is equipped only with HDMI 2.0 ports, so we will have to forget about more advanced features like VRR or support for 4K at 120 Hz. With this equipment, we will have to settle for less if we expect a full set of gaming features.

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.
