Samsung DU8002 (IPS) vs Sony X90L

The HDR effect in the DU8002 television leaves much to be desired. A brightness level of 300 nits is not able to provide a true high dynamic range experience, making the content viewed resemble more of a standard SDR than impressive HDR. Scenes that should dazzle with brightness and detail appear muted and lacking in depth. Nevertheless, the television deserves praise for its high coverage of the DCI-P3 color palette at 92%. As a result, the colors are vivid and saturated, which may satisfy viewers who prefer rich hues, even if the HDR effect does not fully meet expectations.

HDR on the Sony X90L television looks promising. The luminance chart showed that the TV has a solid power reserve, reaching a maximum of 1000 nits in synthetic tests. But how does it perform in real scenarios? In scenes such as the first one from Life of Pi or the final sequence from The Meg, the TV can deliver this power on HDR content, achieving around 800 nits. Unfortunately, displaying small light elements on a black background, as in the scene from Sicario 2, poses greater challenges for the X90L – here the results reach about 600 nits. Despite this, when looking at competitive models with mini-LED technology, the effect looks very good and can shine enough to impress us. The color gamut coverage is also noteworthy, with a result of 96% for DCI-P3 and 76% for BT.2020, indicating good color reproduction in HDR content.

DU8002 offers a Filmmaker mode, which is supposed to provide authentic image reproduction in line with the creators' intentions. Unfortunately, despite the promising name, the results are far from ideal. The white balance in this mode shows significant drops in blue color, leading to a noticeable yellowing of the image, which can be seen, for example, 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 problem 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 DU8002 does not meet expectations and instead of offering high quality, presents an image full of tonal and color inaccuracies.

The best mode in Sony televisions is the IMAX Enhanced mode. Although IMAX is mainly associated with the cinematic experience, here the color reproduction right out of the box is average. In the case of lower quality materials, such as HD – regular TV or YouTube – it is worth paying attention to the white balance. It is characterized by a deficit 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 may cause the image to become washed out and appear as if it is behind a light fog.

In 4K HDR content, the situation looks a bit different. The white balance shows a significant boost in blue, which makes the image appear unnaturally sharp and gives it an artificial feel. Such an exaggeration in color reproduction may not appeal to everyone, especially if one prefers more realistic shades. Additionally, the EOTF curve in Sony X90L looks quite decent at first glance. However, at the end of the graph, there are certain fluctuations that suggest the television is trying to maintain the appropriate brightness to avoid overexposing larger elements.

Samsung is one of those companies that offers advanced tools for improving image quality in its televisions, including a 20-point white balance adjustment. Even with the budget model DU8002, with the right adjustments, surprisingly good results can be achieved. The white balance, especially for HD content, performs really well - tests on the Colour Checker palette confirm accuracy at the level of 2–1.5, which demonstrates the significant capabilities of this television in color reproduction. In 4K content, although not as perfect as in lower quality material, the overall picture looks much better.

The gamma brightness has also been heavily adjusted, ensuring that the image is not overly brightened and looks more natural. What about the EOTF curve? At first glance, it seems fine, but upon closer inspection, especially in film tests, it becomes apparent that the television struggles due to its low contrast panel. The EOTF drops below the reference line. Nevertheless, the DU8002 is an example of a budget model where investing in calibration is worthwhile. Although structural flaws, such as the type of backlighting, cannot be completely eliminated, color accuracy is surprisingly good, especially considering its price.

Sony offers many tools to improve image quality, including two additional image modes that we decided to use during testing and apply calibration to them. This solution significantly facilitates the calibration work and is very effective, provided that the right tools are available. In the case of HD content, the white balance has been almost perfectly aligned – only one shade of gray exceeds the error value of "1", which is an excellent result. The same can be said about the brightness characteristic (gamma), which looks nearly perfect, with microscopic deviations of around 0.01.

In the case of 4K HDR content, the situation is not as ideal. Although the white balance has been significantly improved, it has not been possible to completely eliminate the dominance of blue color. Nonetheless, errors in the Colour Checker test only occasionally exceed the value of "2", which means that image distortions are practically unnoticeable. As for the EOTF curve, it is worth activating the filter in the upper right corner "EOTF in Movies" – the graph looks correct, but the television encounters difficulties illuminating very small elements, which results from the limited number of backlight zones. Despite these minor flaws, it is thanks to the calibration carried out that the IMAX Enhanced mode in the Sony X90L makes watching movies resemble a true cinema experience.

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

Nevertheless, the television handles upscaling, or digital image processing, excellently. The test chart featuring a model looked really good – the image is not overly jagged, and the overall presentation is decent and pleasing to the eye. This is definitely good news for those planning to watch traditional television on this model.

The Sony X90L TV features a tone transition smoothing function known as Smooth Gradation, which is incredibly effective. Even at the "low" setting, 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 gives a natural effect and makes everything look cohesive. It is evident that the engineers really put effort into this aspect, creating a solution that impresses and works well in everyday use. Because of this, even when watching content like regular television or YouTube, where the image is not inherently stunning, one can enjoy a smooth, cohesive, and visually pleasing experience.

DU8002 with a 60 Hz panel is a television that performs better for watching movies than for intense gaming. The motion smoothing feature acts as a fluidizer, smoothing out motion and giving scenes a more fluid appearance, which is useful for movie screenings. In the context of gaming, this model will rather be suitable only for occasional entertainment.

Sony X90L with a 120 Hz panel is a great choice for both gamers and movie enthusiasts. The TV is equipped with the Motion Flow smoothness feature, which allows you to adjust motion smoothness using two sliders: "smoothness" and "clarity." The "smoothness" slider controls the level of motion fluidity, which helps reduce image stuttering, while "clarity" is used to reduce blurring and improve motion sharpness, which is especially useful in dynamic scenes.

DU8002 is a television that will mainly serve as equipment for casual gamers. The 60 Hz panel does not provide the highest motion fluidity, so in dynamic games there may be a lack of that extra smoothness of the image. On the positive side, it features ALLM and HGiG functions, which automatically adjust image settings for HDR games, enhancing the gaming experience. Unfortunately, the television is equipped only with HDMI 2.0 ports, so we have to forget about more advanced features like VRR or support for 4K at 120 Hz. When choosing this equipment, we will have to make do 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 play in high resolution and at a high frame rate. Gamers can also take advantage of the ALLM feature, which automatically switches the TV to low latency mode, and VRR, which provides smooth gameplay without screen tearing. Game Bar is an additional advantage – an intuitive tool that allows for quick access to the most important settings and gaming features, making it easier to control gameplay.

Unfortunately, in terms of HDR in games, the Sony X90L has its limitations. There is no support for HGiG, a standard that many gamers consider essential for precise HDR reproduction in games. Although the TV supports Dolby Vision, which theoretically could 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 along with VRR. This means that despite numerous advantages, gamers seeking perfect HDR in games may feel a sense of disappointment.
