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

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.

When it comes to brightness alone, the S99H is an astronomically bright TV. Its peak brightness in movie scenes can exceed 2800 nits! Regardless of the scene, you can count on powerful HDR effects that practically blind you, and that's exactly what we expect from a top-tier screen. It's inherent to OLED panels that in very bright, full-screen shots they won't sustain as high a brightness as they do 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 was able to maintain 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.

Color gamut coverage

The S99H also handles color exceptionally well, which is a direct result of the QD-OLED panel used here. Regardless of the test scenario, whether synthetic test patterns or measurements with film material in the background, the results stayed at a very high level. The S99H easily covers almost 100% of the DCI-P3 gamut, and for the most demanding color space it reaches nearly 90% of BT.2020. That's top-tier performance on the market. These results match what we saw in the new SQD-Mini-LED screens, and in real movie scenes they even outperform 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 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.

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 creators' intent. Out of the box the TV is tuned very well, though it has minor shortcomings. This mainly concerns a slight drift in white balance in SDR content and a slightly low gamma. As a result, in a darker room the image can be a bit too bright relative to the reference gamma of 2.4, which is the standard for watching films with the lights off. These are of course small issues, since overall color reproduction remains very good and the errors in ColorChecker measurements are small. However, we know that from a screen of the S99H's class you can and should expect even more, so we had it professionally calibrated.

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.

After professional calibration, FILMMAKER mode looks virtually perfect. Because Samsung offers a rich set of advanced calibration features, we were able to tune the colors to an almost perfect level. Most importantly, we were able to even out the white balance and the gamma curve, which resulted in noticeably better contrast and a more natural image dimensionality. With a profile prepared like this, there's really nothing to nitpick or call a flaw. After calibration, the S99H is capable of delivering an essentially reference-quality image.

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 proprietary Samsung NQ4 Gen3 processor handles upscaling and digital image processing. It does a very good job scaling lower-resolution material to 4K. The picture is sharp but doesn't look artificial or overly sharpened. The only fairly specific drawback appears with very old footage shot at 480p or lower. In those cases the TV can slightly crop the edges of the image.

The processor also copes quite well with artifacts visible in low-bitrate material, for example heavily compressed YouTube videos. The noise reduction feature effectively smooths the image and reduces posterization, but it works rather aggressively. It can remove not only unwanted artifacts but also some fine details 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 over keeping every detail, it can be useful.

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.

Another major advantage of OLED panels is excellent motion reproduction. Thanks to the pixels' near instant response time, the Samsung S99H practically produces no smearing. Fast-moving objects don't show noticeable halos or trailing artifacts, so the TV performs very well for both watching sports and gaming. One quirk of OLED screens compared with LCDs is how they render low frame rate material. With very slow camera movement the image can appear noticeably more stuttery. This can be quite effectively mitigated using a frame interpolation system. Samsung lets you adjust judder reduction and blur reduction separately, making it easy to find a compromise between smoother motion and preserving the cinematic character of the content.

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.

Samsung S99H is also an excellent TV for gamers. It offers almost every useful feature... well, maybe except the obvious lack of Dolby Vision for Xbox consoles. It's equipped with four fully functional HDMI 2.1 ports with the full 48 Gbps bandwidth. Thanks to that we can easily use frame-rate synchronization VRR and 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 without 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 mini-map, 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 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 to the competition. The system makes gameplay noticeably smoother. So if someone has their eye on a demanding game (e.g., GTA 6 😉) that runs at only 30 frames per second on console, the S99H can display it much more smoothly than competing models.
