Samsung Neo QLED QN90D / QN92D vs Samsung S85H

During synthetic tests, Samsung QN92D showed its incredible capabilities in terms of brightness. The charts clearly indicate that the television can achieve an impressive 2000 nits, giving it a solid power base to compete with the best models on the market. Such a result places it at the forefront, especially in the context of displaying HDR content, where brightness plays a key role. However, what happens when we move the tests to real film scenes? In favourable conditions, such as the first scene from the movie Life of Pi or the last scene, where the image is completely flooded with light, Samsung QN92D can achieve almost laboratory results, impressing with its brightness. The situation looks different when small, bright objects appear on a dark background, as in the fourth scene from the movie Sicario. In such cases, the television doesn't perform as well – brightness drops several times, and maximum values in the best conditions are around 600 NITS. Similar to contrast, these limitations arise from the use of an aggressive local dimming algorithm. This algorithm aims to reduce the 'halo' effect around bright objects on a dark background, but often at the expense of overall brightness. As a result, while the television performs well in bright scenes, its ability to display full brightness is limited when it comes to small, vivid elements.

Interestingly, the new WOLED SE panel has brought a slight improvement in brightness to the S85 lineup. In the same film scenes last year’s model sat closer to about 700 nits, while the S85H can reach roughly 800 nits. That’s not a change that completely transforms the HDR experience, but the extra headroom is noticeable, especially with point highlights, reflections or stronger special effects. Around 800 nits is a very good result for an entry-level OLED and in most films it’s enough for HDR to have the necessary punch. Bright elements can clearly stand out against perfect blacks, and that contrast is still doing most of the work here. However, you need to remember the typical limitation of OLED technology. When a very bright scene covers a large portion of the screen, brightness can drop to almost half. This is the result of panel protections that limit its output with large bright areas.

Colours

The S85H can deliver very pleasant, saturated colours and in most HDR films it looks really good in that regard. We measured around 95% coverage of DCI-P3, so the palette most commonly used in films is reproduced to a very high degree. Skin tones, greens and stronger reds still have appropriate intensity and under normal viewing it’s hard to have major complaints. Only when you look more broadly at BT.2020 do the limitations of the new WOLED SE panel become apparent. Coverage was about 70%, a bit less than WOLEDs of the previous generation and noticeably less than QD-OLED panels. In films this isn’t a big loss, since most productions rarely use such heavily saturated colours. You’re more likely to notice it in games, where developers more often opt for more intense colours.

The best mode that reproduces colours best on the Samsung QN92D has consistently been the Filmmaker mode for years. While it generally offers decent colour quality, it is not free from significant issues. Let's start with the analysis of HD/SDR image quality. The biggest challenge here is the white balance – the graphs show considerable instability, with a clear dominance of red making the image too warm. This distortion causes hues to be unnaturally shifted towards warmer tones, which can negatively affect the perception of materials with natural colours. Contrast, based on the gamma chart, although not the worst, remains far from ideal, impacting the overall image quality, especially in darker scenes.

This issue also persists with 4K materials, such as series or films of higher quality. In this case, the white balance also turns out to be faulty, with noticeable deficiencies in blue and red colour, leading to tonal shifts. Tests using the Colour Checker tool confirm these problems – all colours tend to skew towards yellow shades, further distorting the natural appearance of the image. Although the Filmmaker mode is one of the best available modes for watching cinematic content, it still requires improvements, especially in terms of colour accuracy and white balance.

To evaluate colours we of course used Filmmaker mode, and in SDR our S85H unit was set very well from the factory. The largest deviation appears in the white balance, where as brightness increases it starts to lose a bit of blue. In practice this means whites and greys have a slightly warmer tint than they should. However, it's not a big fault and during normal viewing it generally isn't very noticeable. Gamma also stays close to the reference value, so the picture is neither overly bright nor unnecessarily dim. The S85H's SDR picture therefore looks really good straight out of the box. A few more imperfections appear in HDR. Here the white balance shifts more with rising brightness, with blue starting to dominate and the red component clearly lacking. This also results in larger errors in some colours. These aren't yet colour errors that completely change the character of the picture, but in direct comparison with the reference the difference is easier to spot. Overall, Filmmaker mode is a very good starting point before professional calibration.

After calibration, the Filmmaker mode on the Samsung QN92D television shows significant improvement, particularly in the SDR content range. The white balance has been greatly enhanced – the previous colour misalignment and dominance of red have been eliminated, resulting in a more natural colour reproduction. In terms of brightness, although the gamma chart did not require significant adjustments, it has been stabilised, which affects the overall picture quality.

Regarding high-quality materials, the white balance has also improved in this case. However, it is worth noting the contrast. The EOTF curve, which illustrates the values in this area, appears correct at first glance. However, upon closer inspection, the television struggles to maintain appropriate contrast in film materials. The EOTF curve reveals some discrepancies, suggesting that despite the progress, there are still areas that require improvement in this aspect. The television continues to strive for excellence in contrast reproduction. A strength of this television is the saturation of colours. Skin tones are rendered very well, and although some colours may be slightly oversaturated, the overall effect looks really attractive – the colours appear rich and vibrant.

Despite some shortcomings in contrast, after calibration, the Filmmaker mode on the Samsung QN92D offers excellent image quality, with natural colour reproduction, making it a great choice for watching movies.

Calibration delivers really good results on the S85H. First and foremost, we were able to set the white balance almost perfectly, which removes the slightly too-warm picture tone previously seen in SDR. Colour reproduction also improves significantly, with most errors falling to very low levels, and in everyday viewing it's hard to find any visible inaccuracies. You can also improve HDR quite a bit, although some issues remain that stem from the TV's inherent characteristics. The S85H doesn't always hold the luminance curve perfectly. The darkest parts are slightly boosted, while, as you approach the panel's limits, you can see small deviations in the brightest highlights. Add to that the limited coverage of the wider BT.2020 colour gamut, which of course cannot be overcome by any calibration. Despite that, the end result is very good, and after calibration the S85H can deliver a really well-tuned, natural image.

Let's check how the Samsung QN92D TV performs with tonal transitions in very poor quality materials. The noise reduction feature shows good effectiveness, improving the fluidity of tonal transitions even in difficult conditions. However, it should be noted that, similar to other Samsung TVs, the effectiveness of this feature can lead to the removal of desirable elements, such as film grain, which can sometimes affect the authenticity of the image.

When it comes to digital processing, the Samsung QN92D TV also performs excellently. During tests, the image looked very good, with the model presented in a natural and correct way. Details, such as branches in the background, were reproduced with great precision, highlighting the TV's ability to enhance the quality of low-resolution materials.

Samsung's S85H uses the same proprietary AI processor, AI NQ4 Gen2, as last year’s S85F, and in terms of digital image processing it performs quite well. Upscaling is one of the model's stronger points. Lower-resolution material is well sharpened, edges look natural and the picture doesn't come across as overly artificial. Just remember a common quirk of Samsung TVs: at very low resolutions you can't completely turn off overscan, so the TV may slightly crop the left edge of the picture. The "noise reduction" function, that is smoothing weaker tonal transitions, also works very well. The processor can effectively remove posterisation and other artefacts visible in lower-quality material. However, be careful with the strength of this function, because Samsung can be fairly aggressive here. When it's activated, along with unwanted artefacts, fine details such as skin or clothing texture also start to disappear.

The Samsung QN92D television is equipped with a 144 Hz panel; however, when watching content using the smoothness feature, the maximum refresh rate is 120 Hz. As a result, both gamers and sports enthusiasts will be satisfied with the picture quality. It’s also worth mentioning the available options for image enhancement, such as the "motion blur and judder reduction" feature, which allows users to adjust smoothness to their individual preferences on a 10-point scale. Motion blur reduction increases the sharpness of fast-moving objects, while judder reduction smooths out motion, eliminating the "stutter" effect. With these advanced settings, one can achieve optimal visual experiences, making the Samsung QN92D perfect for both dynamic scenes and intense gaming.

In terms of motion blur, the television performs really well, and it’s hard to pick faults. The only note we might have is a slight overshoot effect noticeable on dark backgrounds during our test with "Ufoludkiem." Nevertheless, thanks to the advanced smoothness settings, the Samsung QN92D excels in both dynamic scenes and intense gaming.

The S85H uses an OLED panel, so it performs brilliantly when it comes to motion blur. Pixels respond almost instantly, so moving objects don't produce the characteristic ghosting seen on some LCD TVs. This is especially noticeable with sport or fast-paced games, where the picture stays very clean even during rapid motion. The panel itself runs at 120 Hz. That's more than enough for movies, TV shows, sport or console gaming. It's a shame Samsung didn't include a higher refresh rate aimed at PC gamers, as more and more TVs now offer 144 or even 165 Hz at 4K. However, that doesn't affect motion handling in films or sport.

There's also the classic motion smoothing feature with two settings: blur reduction and judder reduction. So you can choose whether films should keep their cinematic 24 frames per second, or whether you'd prefer to smooth them a bit. The S85H gives plenty of freedom here, and the interpolation itself works well and, with sensible settings, doesn't generate too many artefacts.

The television Samsung QN92/QN90 is an excellent choice for avid gamers, deserving of the highest recommendations. This model offers practically all the features available on the market in terms of gaming, making gameplay even more exciting. One of the key differentiators is the 120 Hz panel, which ensures exceptional motion smoothness, crucial during dynamic action games. The television also boasts low input lag, guaranteeing instant reactions to player commands. Additionally, technologies such as VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode) adjust the refresh rate and automatically switch the television to game mode, translating to even better gaming experiences. Another advantage is the Xbox app, which allows gaming of favourite titles directly on the television, eliminating the need for a console. This is a typical feature of Samsung televisions, making them exceptional in the gaming world.

Auto Motion Plus Game is a feature that really deserves praise for Samsung. It is a motion smoother that works wonderfully in games, creating the impression of a higher frame rate – a 30 frames per second image looks like 45, and 60 Hz becomes close to 90 Hz. Importantly, this feature does not introduce significant lag (input lag does not exceed 25 ms), so it does not negatively affect gameplay comfort, unlike many other smoothers available on the market. This allows gamers to enjoy a much smoother image without compromising responsiveness.

Samsung S85H is very well prepared for gaming, essentially regardless of whether you connect a console or a computer. The manufacturer didn’t skimp on connectors and all four HDMI ports support full HDMI 2.1. That means you can use 4K at 120 Hz, VRR and ALLM without worrying which input to plug your console into. With multiple devices that matters a lot, since you don’t have to choose between a console, a PC or a soundbar connected via eARC. The feature set itself is very complete. The S85H supports VRR, FreeSync and automatic switching to Game Mode, and Samsung also offers its expanded Game Bar, which lets you quickly view the key signal parameters and change settings without leaving the game. The only real omission is Dolby Vision, which will matter mainly for Xbox owners. That’s a typical trait of Samsung TVs. Game Motion Plus performs very well and it’s one of the features that has set Samsung TVs apart for years. It smooths motion in games running at 30 or 60 fps, but does so without as large an increase in input lag as a classic motion interpolator. In practice, for slower-paced games, racing or action titles it can genuinely improve motion perception, especially if you’re sensitive to low frame rates.
