Samsung DU8002 (IPS) vs Samsung OLED S95H (S99H) (QD-OLED)

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.

When it comes to brightness alone, the S99H is an astronomically bright TV. Its peak brightness in film scenes can exceed 2800 nits. Whatever the scene, you can count on powerful HDR effects that are almost blinding, exactly what you expect from a top-tier screen. It is the nature of OLED panels that they cannot sustain the same extreme brightness in very bright, full‑screen frames as they can with small highlights, but the results are still excellent. In a bright scene from the film The Meg, the sun still exceeded 2200 nits. That means the S99H managed to sustain higher brightness than most Mini LED displays on the market. In terms of brightness, the S99H is currently the best OLED TV we have tested.

Colour gamut coverage

The S99H also handles colour extremely well, which is a direct result of the QD-OLED panel used here. Whether the test scenarios were synthetic test patterns or measurements taken with film material playing in the background, the results remained at a very high level. The S99H easily covers almost 100% of the DCI-P3 gamut, and for the more demanding BT.2020 colour space it reaches nearly 90%. That is absolute top-tier performance. These results match what we have seen in the new SQD-Mini-LED screens, and in real film scenes even outperform RGB Mini LED displays.

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.

Samsung offers a whole host of picture modes and features, but as usual we recommend choosing Filmmaker Mode, especially if you want the most faithful rendering of the filmmakers' intent. Out of the box the TV is tuned very well, although it has minor shortcomings. These are mainly a slight drift in the white balance in SDR content and a slightly low gamma. As a result, in darker viewing conditions the picture can be a little too bright compared with the reference gamma of 2.4, which is the standard for watching films with the lights off. These are, of course, minor points, because overall colour reproduction remains at a very good level and the errors in the ColorChecker measurements are not large. However, we know that with a screen of the S99H's class you can, and arguably should, expect even more, which is why we carried out a professional calibration.

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.

After professional calibration, FILMMAKER mode looks practically perfect. Because Samsung offers a rich set of advanced calibration features, we were able to fine-tune the colours to an almost perfect level. Above all, we managed to even out the white balance and the gamma curve, which resulted in noticeably improved contrast and proper image modelling. In this tuned picture profile there really isn't a single thing to criticise or call a flaw. After calibration, the S99H can deliver an essentially reference-quality image.

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 proprietary Samsung NQ4 Gen3 processor is responsible for upscaling and digital image processing. It handles upscaling lower-resolution material to 4K very well. The picture is clear without looking artificial or overly sharp. The only rather specific drawback appears with very old material recorded at 480p or below. In such cases the TV can slightly crop the edges of the picture.

The processor also copes quite well with artefacts visible in lower bit-rate material, for example heavily compressed YouTube videos. The noise reduction function effectively smooths the image and reduces posterisation, but it operates quite aggressively. It can remove not only unwanted artefacts but also some fine detail, and even natural film grain. Wanting to preserve the source material as faithfully as possible, we decided not to use it. However, if someone prefers a clean, as-smooth-as-possible picture over retaining every detail, it may prove useful.

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.

Another major advantage of organic OLED panels is their excellent motion handling. Thanks to the pixels' virtually instantaneous response time, the Samsung S99H exhibits virtually no motion blur. Fast-moving objects do not produce visible halos or trailing outlines, so the television performs very well for both watching sport and gaming. One characteristic of OLED screens compared with LCDs, however, is the way they render low-frame-rate material. With very slow camera movement the image can appear noticeably more 'choppy'. This can, however, be fairly effectively mitigated using a frame-interpolation system. Samsung lets you adjust judder reduction and blur reduction separately, so it's easy to find a compromise between smoother motion and preserving the cinematic character of the content.

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.

The Samsung S99H is also a great TV for gamers. It offers almost every possible and useful feature... well, except for the obvious lack of Dolby Vision for the Xbox console. It's equipped with four full-bandwidth HDMI 2.1 ports that offer the full 48 Gbps. This lets you use VRR frame-rate synchronization and the automatic game mode (ALLM) without any problems. This year Samsung also has no issues properly supporting HGiG, so HDR setup on a console is quick and straightforward. Samsung's TVs are also known for interesting extras. In the Game Bar menu you'll find options to add an on-screen crosshair, enlarge the minimap or change the displayed image's aspect ratio (PC).

Particularly noteworthy is Samsung's Game Motion Plus feature. It's Samsung's proprietary motion-smoothing system that uses interpolation to increase smoothness in games. Input lag then rises to around 40 to 50 ms (depending on the strength of the setting), which is an excellent result compared with the competition. The system makes gameplay noticeably smoother. So if someone has their eye on a demanding game (e.g. GTA 6 😉) that runs on a console at only 30 frames per second, the S99H can display it much more smoothly than competing models.
