Samsung DU8002 (IPS) vs Sony X90L

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

HDR on the Sony X90L television looks promising. The luminance chart indicated that the TV has a solid power reserve, achieving a maximum of 1000 nits in synthetic tests. But 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 capable of delivering that power on HDR content, reaching around 800 nits. Unfortunately, displaying small light elements on a black background, like in the scene from Sicario 2, presents greater challenges for the X90L – here the results reach around 600 nits. Nevertheless, when looking at competitive models with mini-LED technology, the effect looks very good and can shine enough to impress us. The colour gamut coverage is also noteworthy, with a result of 96% for DCI-P3 and 76% for BT.2020, which indicates good colour 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 its promising name, the effects are far from ideal. The white balance in this mode shows significant drops in blue colour, leading to a noticeable yellowing of the image, as seen in our comparison photo. Colour Checker tests confirm these errors. Regarding 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 materials shows significant increases above the reference line, leading to overly bright small light elements. As a result, the Filmmaker mode in DU8002 does not meet expectations and instead of providing high quality, presents an image full of tonal and colour inaccuracies.

The best mode on Sony televisions is the IMAX Enhanced mode. Although IMAX is mainly associated with the cinema experience, the colour reproduction out of the box is average here. In the case of lower quality materials, such as HD – regular television or YouTube – it's worth paying attention to the white balance. It suffers from a shortfall in red and excessive dominance of blue, which gives the image a pinkish hue. The brightness characteristic, or gamma, for HD content is quite acceptable, but a slight boost can cause the image to appear washed out and look as if it’s behind a light fog.

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

Samsung is one of those companies that offers advanced tools to enhance picture quality in its televisions, including a 20-point white balance adjustment. Even in the budget model DU8002, after proper 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 levels of 2–1.5, which indicates the significant capabilities of this television in colour 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 significantly adjusted, meaning the image is not overly brightened and appears more natural. What about the EOTF curve? At first glance, it seems fine, but upon closer inspection, especially in film tests, it's clear that the television struggles due to its low-contrast panel. And the EOTF drops below the reference line. Nevertheless, the DU8002 is an example of a budget model where investing in calibration is worthwhile. Although construction flaws, such as the type of backlighting, cannot be completely eliminated, colour accuracy is surprisingly good, especially considering its price.

Sony offers many tools for improving picture quality, including two extra picture modes that we decided to use during testing and apply calibration to. This solution greatly simplifies the calibration process and is very effective, provided you have the right tools. In the case of HD content, white balance was almost perfectly aligned – only one shade of grey exceeds an error value of "1", which is a great result. The same can be said for the brightness characteristic (gamma), which presents almost perfectly, with microscopic deviations of around 0.01.

For 4K HDR content, the situation is not as ideal. Although white balance has been significantly improved, it was not possible to completely eliminate the dominance of blue. Nevertheless, errors in the Colour Checker test only occasionally exceed the value of "2", which means that picture distortions are practically unnoticeable. When it comes to the EOTF curve, it's worth activating the filter in the top right corner "EOTF in Films" – the graph looks correct, but the TV struggles with illuminating very small elements, which is due to the limited number of backlight zones. Despite these minor errors, it's thanks to the calibration that the IMAX Enhanced mode in the Sony X90L makes watching movies feel like a true cinema experience.

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

Nonetheless, the television handles upscaling, or digital image processing, exceptionally well. The test pattern with the model looked really good – the image isn't 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 television features a smooth tonal transition function known as Gentle 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's clear that the engineers have really put effort into this aspect, creating a solution that impresses and performs well in everyday use. This means that even when watching content like regular television or YouTube, where the image is by nature not stunning, you can enjoy a smooth, coherent, and visually pleasing experience.

The 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 fluid enhancer, smoothing out movement and giving scenes a more fluid appearance, which is useful for movie sessions. In the context of gaming, this model is likely only suitable for occasional entertainment.

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

DU8002 is a television that is mainly suited for casual gamers. The 60 Hz panel won't provide the highest motion fluidity, so in dynamic games, you might miss that extra smoothness of the image. On the plus side, it has ALLM and HGiG functions, which automatically adjust the picture settings for HDR games, enhancing the gaming experience. Unfortunately, the TV only comes with HDMI 2.0 ports, so we have to forget about more advanced features like VRR or support for 4K at 120 Hz. Choosing this equipment means we will have to make do without a full set of gaming features.

Sony X90L is a TV 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 high frame rates. Gamers can also take advantage of the ALLM feature, which automatically switches the TV to low latency mode, and VRR, which ensures smooth gameplay without frame tearing. The Game Bar is an added bonus – an intuitive tool that provides quick access to essential settings and gaming features, making it easier to control the gameplay.

Unfortunately, when it comes to HDR in games, the Sony X90L has its limitations. It lacks support for HGiG, a standard that many gamers consider crucial for accurate HDR representation in games. While the TV supports Dolby Vision, which theoretically could enhance image quality in games, the practical implementation of this feature is problematic. Dolby Vision in game mode comes with very high input lag, making gameplay less comfortable and precise movements more difficult. Additionally, Dolby Vision cannot be enabled alongside VRR. This means that despite numerous advantages, gamers seeking the perfect HDR in games may feel unsatisfied.
