Samsung OLED S85F / S84F (QD-OLED) vs Philips MLED920 / MLED910

As an OLED, the Samsung S85F can really shine – literally. Under favorable conditions, it can generate brightness exceeding 750 nits. This is hugely significant because most movies are created with displays around 1000 nits in mind. In practice, this means that in scenes with moderately large bright elements, the image can look simply fantastic. However, it's not always so rosy. When there is a massive amount of light on the screen – whether it's a vast bright background or an entire screen filled with white – the S85F must tone it down. The brightness can drop by even four times in such scenes. This limitation is known to basically every OLED in this price range, so we don't consider it a particular failing. However, something that deserves praise is what sets this model apart from the competition – color gamut coverage. Thanks to the QD-OLED panel, our colorimeter showed values exceeding 100% DCI-P3 coverage and as high as 86% for the ultra-wide BT.2020 palette. Such results are hard to find even in televisions that cost several times more.

In our measurements, the Philips MLED920 achieved even around 900 nits in static tests, which is a really solid result for a mid-range TV. In practice, this translates to a lot of satisfaction during viewing sessions – in scenes rich in bright light, such as the first, third, or fifth test screens, the screen was able to generate about 700 nits, which is enough to feel the true "HDR effect." However, it cannot be denied that the limited number of backlighting zones and the compromises of mini-LED dimming algorithms in more demanding scenes reveal their nature. In sequences with small light sources – such as the moon or a scene from the movie Sicario 2 – the television clearly prioritizes maintaining deeper blacks at the expense of the brightness of those small elements. For most viewers, this is still a reasonable compromise, as the dark background tends to look much better, though one must be aware that the details themselves may not impress with intensity. There is also some disappointment regarding colors. Although the applied PFS filter (the equivalent of quantum dots known from QLEDs) does its job and colors appear quite vivid, the coverage of the DCI-P3 color space reaches "only" 90%. In everyday viewing, this will be sufficient, but in extremely colorful productions – such as the latest Disney animations – one can notice that some tones are not as vibrant as they could be in other constructions.

Samsung, as befits a manufacturer with ambitions, equipped the S85F with a mode called Filmmaker. Its task is simple: to make the colors on the newly purchased television as true to what the director wanted us to see as possible. Sounds great… but, as often happens, a great-sounding theory doesn’t always translate into perfect practice.

In the tested unit, it quickly became apparent that the image – due to an excess of blue and red – looked as if someone had overdone the saturation a bit. As a result, quite significant color errors appeared, particularly in 4K content. To make matters worse, there was a brightness issue – the S85F could brighten most scenes more than it should, taking away their intended mood.

Fortunately, Samsung televisions, including the S85F, offer an impressive number of settings for advanced calibrators. This means we could check what this panel is truly capable of when it gets into the right hands.

Like every Philips television we tested, we primarily evaluated the MLED920 in Filmmaker mode – this is supposed to be the "most honest" mode, designed for films and to faithfully convey the creators' intentions. Indeed, in terms of colorimetry, it performs the best among all the modes available on the television, but it is not without its flaws. The first thing that stands out is the white balance. The image has a slight tendency to take on purple-pink tones, which gives it a somewhat unnatural character. However, an even bigger problem turned out to be what we mentioned earlier – image clipping. Just look at the gamma or EOTF graphs to see that the line deviates significantly beyond the norm, falling below the value of 1.8. In practice, this means "clipping" the brightest whites, where the image becomes almost milky. Fortunately, most of these issues can be corrected – the MLED920 responds to calibration, and with a few adjustments, the image quality can be significantly improved.

Thanks to the vast number of settings in the menu, we managed to bring the S85F almost to perfection. White balance in SDR content? Literally perfect – deviations do not exceed a value of "1". Thus, it can be confidently said that in materials with not very high dynamics, we have an image close to reference.

In HDR content, minor issues did arise, but they are of little significance in practice – most errors fall below the threshold of perception, which is a value of "3". We also managed to tame the S85F regarding brightness management – the EOTF curve, even in films, adheres to an almost perfect line. This is one of those cases where after calibration, you can comfortably forget about the settings and simply enjoy movies and series at the highest level.

After calibration, we managed to largely tame the white balance – to the extent that the average viewer will not be able to detect color inaccuracies. The characteristic pink-purple glow that previously disturbed the naturalness of the picture has also disappeared. The color palette has been organized, and the colors appear more consistent and neutral. The gamma in SDR content after calibration looks really good – there's no sign of the earlier “bleeding” effect in bright scenes. The picture has become more contrasted and devoid of the milkiness that previously spoiled the perception significantly. In the case of HDR content, the improvement is also noticeable, although it is still evident that the television is “doing its own thing.” The EOTF curve cannot be fully shaped, as Philips simply does not provide tools in its settings that allow for precise control over this parameter. In many films, the television simply still showcases the image “in its own way.” Despite these limitations, calibration has brought quite a lot of good – it has managed to minimize most of the color inaccuracies and significantly improve the overall balance of the picture. However, it must be remembered that certain barriers arise from the very hardware construction and they simply cannot be overcome.

The tone transition smoothing feature in the S85F works really well – it can completely eliminate the problem of visible bands in very poor quality materials, even from YouTube. Unfortunately, even the lowest level of this option comes with compromises. Noise reduction is aggressive enough that it can smooth out film grain, which many of us consider an element of the cinematic atmosphere. At the "Standard" level, we did not notice that this feature removed anything significant from the image, so we can recommend this setting. On the other hand, the "High" level is a different story – it can smooth not only noise but also fine, desirable details such as the texture of objects.

When it comes to image scaling, the S85F performs very well. The material looks sharp, and the only minor imperfection is slightly visible contour jaggedness. And there’s the ongoing issue with Samsung televisions – overscan. This can cause some scenes to have their frames slightly trimmed, which is worth keeping in mind when watching very old content.

The manufacturer equipped this model with several features that improve signal quality, and although we usually approach such "enhancers" with skepticism, they turn out to be really helpful here. The key option is called "distortion reduction" – it works best at a medium level because, on one hand, it effectively smooths out unwanted banding and color transitions, while on the other, it doesn't excessively cut details, which keeps the image looking natural.

The situation is a bit worse with upscaling. Lower quality materials – such as test videos with models – appeared soft and lacking in sharpness. Yes, this can be somewhat corrected with the sharpness slider in the menu, but the effect still remains far from what competitors in a similar price range offer. Philips therefore still needs to work on this aspect because, in light of the successful improvement of tonal transitions, the upscaling simply performs poorly.

S85F is a hellishly fast television – and this is not just an empty catchphrase for effect. Thanks to the 120 Hz OLED panel, dynamic scenes, whether in games or while watching a live match, look exactly as they should – smoothly, sharply, and without the feeling that something is "escaping" from the frame. The lightning-fast pixel response time, typical of OLEDs, plays a crucial role here. Transitions between frames are practically instantaneous, and the image remains clear even during the fastest camera movements. A ball flying across half the field? A car racing in a chase scene? Everything here is clear and free of the characteristic "trail" found in LCDs.

This is exactly what we expect from a good OLED – zero compromises in motion fluidity. The S85F gives the feeling that regardless of the pace of the action, we can focus on what is happening on the screen, rather than on the imperfections of the image.

The Philips MLED920 features a 144 Hz panel, which immediately suggests that we shouldn’t complain about motion smoothness. And indeed – the motion blur is relatively low here for a VA panel, and although one might occasionally notice slight issues on darker backgrounds, they are not something that most people would notice during regular viewing.

A major plus is the presence of a motion smoother called "Motion Style." It allows you to adjust the smoothness to your own preferences – if someone prefers a more “theatrical,” almost television-like image, they can increase the sliders, and if they want to preserve the natural “jitter” of a cinematic frame, they just need to set lower values. This way, everyone can find the perfect balance.

[UPDATE] We have updated our 2025 Samsung TV reviews following the release of firmware version 1131, which officially restores the essential HGiG (HDR Gaming Interest Group) support.

The S85F has practically everything it needs to become the dream screen for gaming. Four fully-fledged HDMI 2.1 ports with a bandwidth of 48 Gb/s, support for VRR, ALLM, a super-detailed Game Bar that clearly shows all parameters – and on top of that, a gem in the form of Game Motion Plus. This is a motion interpolator that makes animation in games more enjoyable, with only a slight increase in input lag. This is a rare combination, and Samsung deserves a big plus for it. Now comes the moment where we have to complain a bit. The lack of Dolby Vision in Samsung TVs is already standard, so there's no point in hoping (unless something changes in a few years) – but the disappearance of HGiG after the software update is something that’s hard to explain. HGiG (which stands for HDR Gaming Interest Group) is a mode that allows for precise reproduction of brightness in HDR games, according to the creators' intention. Without it, HDR calibration on the console becomes less precise, so we might end up with an image that's too dark in the shadows or overly bright. Perhaps Samsung will fix this in the next update – and we have high hopes for that. Because if HGiG returns, the S85F will become almost the perfect TV for gamers.

For gamers, the Philips MLED920 is truly a complete tool. The manufacturer has taken care of everything that today is considered standard in televisions designed for consoles and PCs. It features ALLM, so the console automatically switches the screen to game mode, it has VRR and 144 Hz refresh rate, which guarantees smooth gameplay even in fast titles. All key HDR formats are supported – including HGiG and Dolby Vision Gaming for Xbox – which means that regardless of what you are playing and on which console, the TV will be able to extract maximum potential from the image. In everyday gaming, the Game Bar also proves to be useful – a relatively simple implementation by Philips, but a functional panel where you can quickly check image parameters, turn on VRR, or adjust details without leaving the game. It may not be as advanced as the competition's offerings, but it performs its job flawlessly. And lastly, something that distinguishes Philips from its competitors – Ambilight. The three-sided LED backlighting can make a huge impression in games, especially in the evening. It also provides a way to slightly "expand" the screen and feel greater immersion. And since colorful LEDs have recently become almost a mandatory element of a gamer’s room, the MLED920 fits into this trend perfectly.
