Samsung Neo QLED QN95D vs SAMSUNG S90F (WOLED)

Samsung QN95D handles HDR exceptionally well, achieving peak brightness around 2000 nits. In tested movie scenes where the screen is fully illuminated, the TV delivers intense and realistic HDR content reproduction, significantly enhancing the quality of visual experiences. However, similar to the contrast, the dimming algorithm can sometimes exhibit limitations. Despite a significant number of Mini LED zones, the TV won’t amaze users with incredible lighting. For example, in scenes from "Life of Pi," where a bright moon appears against a dark background, and in segments of "Sicario 2," featuring intense lighting effects on a dark backdrop, the TV shows very poor performance. During such moments, the TV attempts to reduce the halo effect by dimming the image to a level reminiscent of SDR quality. This results in deep and uniform blacks, but at the cost of losing some details in bright areas. It’s a compromise aimed at maintaining the best possible black quality, although it does make the image lose some of its dynamism. Despite some flaws in the local dimming algorithm's performance, this TV deserves praise for its wide coverage of the DCI-P3 colour gamut. This is made possible by the use of a quantum dot coating, also known as QLED technology, which allows for vibrant and rich colours.

Does the S90F handle not only blacks but also bright parts of the image? Definitely. The stories about OLEDs as "dark screens" can slowly be regarded as myth. The Samsung S90F, like the LG C5 based on a very similar panel, achieves brightness exceeding 1000 nits. This is a value more than enough to enjoy impressive and dynamic HDR images – both in movies and series. Most of the scenes we tested look stunning, with well-defined highlights and high contrast. Of course, OLED technology still has its limitations – in very bright, full-screen sequences, such as the test card from the movie The Meg (photo 5), the television may noticeably dim the image. However, it should be emphasized that such scenes are rare. It can be said that the HDR effect is good enough that even mid-range OLED models like the S90F can provide a cinematic experience in the home living room.

In the category of factory colour reproduction, the Samsung QN95D television has been tested in Filmmaker mode, which offers the best settings from the manufacturer. However, it is not entirely free of flaws. For HD content, there is a significant colour discrepancy, particularly in the white balance, where the red colour clearly dominates the graph. The situation improves with 4K HDR content, but there are still significant drops in blue colour reproduction. These effects can be observed in a scene from the film "Star Wars," where the main character is rendered in overly warm tones.

In terms of contrast, the gamma graph shows a large initial spike, indicating that the television effectively highlights the brighter parts of the image. However, at the end of the graph, we notice a significant drop, which may mean that details may be lost in darker tones. This shape of the gamma curve can affect how users perceive dark scenes, where some details may become too blurred or too dark, causing the image to lose clarity. It's also worth noting the curve corresponding to brightness (EOTF), which is quite correct, except for the initial drop.

Although the Samsung QN95D boasts impressive specifications and advanced technologies to earn the title of one of the best televisions on the market, it requires some improvements in colour reproduction and contrast to fully realise its potential.

Samsung S90F, like most modern televisions, offers many picture modes, but – following our testing tradition – we checked it out in the best one, which is the Filmmaker mode. Thanks to this, the image looks much more natural than in the default, often oversaturated settings. It was neither overly saturated nor artificially dimmed – simply closer to what one should see. Of course, “more accurate” doesn’t mean “perfect”. Unfortunately, our S90F had significant issues with white balance, particularly in the blue color range, resulting in a slightly yellowish filter being applied to most scenes. Someone might say it looks more “filmic” – because it’s warmer – but let’s not kid ourselves, George Lucas didn’t film Star Wars in sepia 😉 (you’ll find a comparison with the scene below as always).

Additionally, in HDR materials, there was an issue with brightness management. The EOTF curve showed a clear “spike” in brightness – the television brightened the image more than it should have, causing some effects to look too intense and deviating from the reference. Fortunately, some of these problems can be eliminated through professional calibration – you’ll read about its effects later in the review.

After calibration, the picture on the Samsung QN95D television achieves truly impressive results. The white balance is perfectly balanced, and error readings rarely exceed a value of 2, which means that colours are displayed very accurately. Most samples from the Color Checker test fall within an acceptable error range, confirming that the television reproduces colours excellently. The contrast has also improved significantly, and the gamma curve is more stable, leading to better visibility of details in dark and bright scenes. However, it is worth noting the EOTF (Electro-Optical Transfer Function) curve, which shows some discrepancies in film tests. Although the television performs well in most scenes, in more extreme cases, details in black can still be lost - this is due to an aggressive dimming algorithm.

Nevertheless, these minor imperfections do not diminish the overall picture quality. After calibration, the Samsung QN95D delights with its visual quality, offering an exceptional experience that will certainly please anyone looking for a top-of-the-line television.

After calibration, we managed to eliminate practically all the previously mentioned errors. Older movies in SDR quality finally look like they should – without the sepia effect or artificial aging of the image. The atmosphere of the classics is back in place (no thanks needed, Star Wars fans), and the colours no longer resemble an Instagram filter.

One of the key changes was also the improvement of brightness characteristics in HDR content. We managed to control the EOTF curve in almost a reference manner. Admittedly, the most demanding users may detect minimal deviations in brightness, but honestly – most viewers won't even notice that. And it's no surprise because the vast majority of errors fall below the ΔE 3 value, which is below the threshold of visibility. After calibration, the S90F (WOLED) becomes a truly excellent display – one on which you can enjoy nearly perfect image quality.

The Samsung QN95D television handles tonal transitions well, even in lower-quality materials, thanks to the noise reduction feature, which acts like a gentle gradient. This feature is incredibly effective, smoothly rendering the image and eliminating unwanted noise while significantly improving the quality of the displayed content. However, as is often the case, excessive effectiveness can lead to unintended side effects. In some materials, this feature can also blur elements that should remain sharp, such as film grain.

Despite this, the television performs well in terms of image scaling, eliminating larger jaggedness in the picture. In a scene where branches are visible, they are not overly artificially sharpened, which allows for a natural appearance, and the model does not have an artificial outline. Overall, this means that even in more challenging conditions, the film material presents itself satisfactorily on the Samsung QN95D. The only downside when watching HD/SD content (like regular terrestrial television) is that we have a slightly cropped image - this is caused by the so-called overscan, which cannot be turned off.

Digital Image Processing in S90F:

Fortunately, Samsung, like in most of its models, manages to effectively tackle the unwanted posterisation effect in the S90F. The function responsible for this element is noise reduction, which does a pretty good job of smoothing tonal transitions and eliminating unnatural colour blending – of course, within its capabilities. Unfortunately, it works quite aggressively, so using it comes with trade-offs. In addition to improving gradation, it can also remove film grain or slightly soften facial features. In this case, the choice is yours – do you prefer a more "clean" image, or do you care about preserving the original texture of the material.

Image Scaling in S90F:

In this year's model, Samsung has implemented its proprietary AI processor – NQ4 Gen3, which really handles upscaling quite well. In our test scenes, the TV effectively "pulled up" lower quality towards artificial 4K – the image was more enjoyable to view, and the differences in sharpness between native and scaled content were minimal. Unfortunately, behind all this AI marketing façade lies a certain shortcoming. The S90F struggles with overscan. If you reach for truly archival material – e.g. a VHS tape of your parents' wedding – you have to reckon with the fact that the lower part of the image may get cut off. The function to adapt the image to resolution simply does not work as it should here.

The panel in Samsung QN95 performs very well in terms of motion blur and fluidity. With a refresh rate of 120 Hz and features that reduce blur and jitter, users can adjust the picture settings to their personal preferences, whether for watching films or dynamic sports broadcasts. Users have the ability to customise the motion smoothness on a 10-point scale – from a more frame-like appearance, reminiscent of traditional film, to a smooth, almost theatrical effect that works especially well in sports broadcasts.

S90F really handles motion excellently – after all, it’s an OLED with a 144 Hz panel, so sports and games look absolutely stunning on it. The image is smooth, clear, and there’s no room for ghosting or blurring, which can sometimes plague cheaper LCDs.

The TV also comes equipped with motion smoothness settings that allow you to customise everything to your liking. We have motion blur reduction and judder reduction – you can set it so that the image is super smooth (even to the point of looking a bit soap opera-like), or more cinematic, with the classic “jumpiness” of 24 frames. The choice is yours, Samsung imposes nothing.

Samsung QN95D offers a fair bit of features that gamers will appreciate. First and foremost, the television supports Variable Refresh Rate (VRR), which allows for smoother gameplay by eliminating screen tearing issues, especially during dynamic scenes. There's also the Auto Low Latency Mode (ALLM), which automatically switches the TV to low latency mode when it detects a connected console or computer, providing more responsive control.

Additionally, the QN95D Samsung has a gaming mode that reduces input lag to a very low level, which is crucial in games where reflexes play an important role. With a high refresh rate of 120 Hz, the image is exceptionally smooth, significantly impacting the experience of dynamic action games and sports productions. The television also supports G-Sync and FreeSync technologies, which further enhance gameplay smoothness and improve user comfort. An interesting addition is the 'Game Bar' – a special menu that provides quick access to all game-related settings, allowing easy adjustment of the image and parameters to the user's preferences without the need to pause the gameplay.

Although the Samsung QN95D does not support Dolby Vision – which is quite obvious for Samsung TVs – it does offer the HGiG feature, which ensures appropriate image quality in HDR games, in line with the creators' vision.

When it comes to gaming features – the S90F has absolutely nothing to complain about. Aside from the lack of Dolby Vision, which is already the norm for Samsung. The television operates at 144 Hz, has four HDMI 2.1 ports, so you can easily connect more than one console or PC. Onboard, we also find Game Bar – a practical tool that allows you to quickly preview picture settings, VRR status, ALLM mode, and other useful options. Game Motion Plus deserves special mention – Samsung's proprietary motion smoother that actually works sensibly in games. The image appears smoother, but without any artificial effects or slowdowns.

It's also worth mentioning the HGiG feature, which – and this may be a slight surprise – works correctly. We bring this up because Samsung clearly messed something up in one of the recent updates, and in some models, the option responsible for HGiG simply... disappears from the menu. Setting it up becomes almost impossible. Fortunately, our S90F unit did not have this issue, but the situation is dynamic, so it's worth keeping this in mind and regularly checking for new software versions and information from the manufacturer.
