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 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.

When it comes to pure brightness, the S99H is an astronomically bright TV. Its peak brightness in film scenes can exceed 2,800 nits. Whatever the scene, you can expect powerful HDR effects that are almost blinding, which is exactly what we want from a top‑tier display. By nature, an OLED panel can't maintain that extreme brightness in very bright, full‑screen frames the way it can with small bright highlights, but the results are still excellent. In a bright scene from The Meg the sun still exceeded 2,200 nits. That means the S99H was able to hold a higher brightness than most Mini LED screens on the market. In terms of brightness the S99H is currently the best OLED TV we've tested.

Colour gamut coverage

The S99H also handles colours exceptionally well, thanks directly to the QD‑OLED panel used here. Whether the test used synthetic test patterns or measurements with film material in the background, the results remained very high. The S99H easily covers almost 100% of the DCI‑P3 gamut, and in the most demanding space, BT.2020 it reaches nearly 90%. That's absolute top‑tier performance. These results match what we saw in the new SQD‑Mini‑LED displays, and in real film scenes they even surpass RGB Mini LED displays.

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.

Samsung offers a whole host of picture modes and features, but we traditionally recommend choosing FILMMAKER mode, especially if you want the most faithful rendering of the creators' intent. Out of the box the TV is tuned very well, though it has minor flaws. These are mainly a slight deviation in white balance in SDR content and a slightly low gamma. As a result, the picture in a dark room can be a little too bright compared with the reference value of 2.4, which is the standard for watching films with the lights off. These are, of course, small issues, because overall colour reproduction remains very good and the errors in ColorChecker measurements are not large. However, we know that for a screen of the S99H's calibre you can and should expect even more, so we subjected it to professional calibration.

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.

After professional calibration, FILMMAKER mode looks practically perfect. Because Samsung offers a rich set of advanced calibration controls, we were able to 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 correct image modelling. In a profile prepared like this there really isn't a single thing to pick apart or call a fault. After calibration, the S99H can deliver an essentially reference-quality picture.

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.

Upscaling and digital image processing are handled by Samsung's proprietary NQ4 Gen3 processor. It copes very well with scaling lower-resolution content to 4K. The picture is clear without looking artificial or overly sharp. The only fairly specific drawback appears with very old material recorded at 480p or lower. In such cases the TV can slightly crop the edges of the image.

The processor also does a decent job with artefacts visible in low-bitrate material, for example in heavily compressed YouTube videos. The noise reduction function effectively smooths the picture and reduces posterisation, but it works quite aggressively. It can remove not only unwanted artefacts but also some fine detail, and even natural film grain. We, wanting to preserve maximum fidelity to the source material, chose not to use it. However, if someone values a clean, as-smooth-as-possible image more than keeping every detail, it may prove useful.

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.

Another major advantage of organic panels is very good motion handling. Thanks to the pixels' near-instant response time, the Samsung S99H shows virtually no smearing. Fast-moving objects don't produce visible halos or trailing artefacts, so the TV performs very well for both sport and gaming. One quirk of OLED screens compared with LCD is the way they render low-frame-rate material. With very slow camera movement the picture can appear noticeably more juddery. This can be quite effectively mitigated using frame interpolation. Samsung lets you adjust judder reduction and motion blur reduction separately, so it's easy to find a compromise between a smoother picture and preserving the cinematic feel of the content.

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.

Samsung S99H is also a top TV for gamers. It offers almost every possible and useful feature... well, perhaps except the obvious lack of Dolby Vision for the Xbox console. It’s equipped with four full-fledged HDMI 2.1 ports with the full 48 Gbps bandwidth. That makes it easy to use frame-rate synchronization VRR or automatic low-latency mode (ALLM). This year Samsung also has no issues with proper HGiG support, so HDR setup on a console is quick and free of unnecessary complications. Samsung is also known for interesting extras in its TVs. In the Game Bar menu you’ll find options to add an on-screen crosshair, enlarge the minimap, or change the aspect ratio of the displayed image (PC).

Particularly noteworthy is Samsung’s feature: Game Motion Plus. It’s Samsung’s proprietary motion-smoothing system that uses interpolation to boost smoothness in games. Input lag then rises to around 40 to 50 ms (depending on the strength of the setting), which, compared with the competition, is an excellent result. 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 fps, the S99H can display it much more smoothly than competing models.
