Philips MLED920 / MLED910 vs Samsung S85F (WOLED)

Philips MLED920 in our measurements in static tests even reached around 900 nits, which for a mid-range model is quite an impressive result. In practice, this translates to a lot of satisfaction during viewing – in scenes rich in bright light, such as the first, third, or fifth test patterns, the screen was able to generate around 700 nits, which is sufficient to feel the real "HDR effect". However, it cannot be denied that the limited number of backlight zones and the typical mini-LED compromises in dimming algorithms reveal their flaws in more demanding scenes. In sequences with small light sources – like the moon or a scene from the film Sicario 2 – the television clearly prioritises maintaining deeper blacks at the expense of the brightness of these small elements. For most viewers, this is still a reasonable compromise, as the dark background looks much better, although it should be noted that the details themselves may not dazzle with intensity. The question of colours also leaves a bit to be desired. Although the employed PFS filter (the equivalent of quantum dots known from QLEDs) does its job and the colours appear quite vibrant, the coverage of the DCI-P3 colour space reaches "only" 90%. In everyday viewing, this will be sufficient, but in extremely colourful productions – like the latest Disney animations – one can notice that some tones are not as vivid as they could be in other constructions.

For most of the time, let's say in 90% of film scenes, viewers will hardly see any difference between the S85F versions. When small but very bright light points appear on screen – a lantern in a dark alley, a gunshot, the sun breaking through the clouds – this WOLED panel (just like the smaller S85F) performs exceptionally well. Our measurements showed a peak brightness of around 750 nits. We can confidently state: this is a great result that guarantees fantastic HDR effects. The problem arises in a very specific, uncomfortable situation for any OLED. We're talking about the moment when the entire screen has to shine at full brightness clearly. Examples include a white background screen, a skiing scene, or our test sequences (5) from the film The Meg. And here, unfortunately, the results diverge quite significantly against the WOLED panel variant. Our measurement equipment was able to measure a maximum of around 250 to 300 nits of brightness under such conditions. To be clear: the same model on a QD-OLED panel in the same test is almost twice as bright. The second issue: colours. And here we also have to be honest – QD-OLED has a structural advantage. Why? It’s simple. QD-OLED creates colours from three components (red, green, and blue) and doesn’t need an additional white subpixel. The WOLED panel we’re testing here uses that white subpixel, mainly to boost overall brightness. The effect is that QD-OLED is able to display a slightly wider colour palette, and the colours are a bit "cleaner." But let’s be clear: it’s not that the colours on this WOLED panel are bad! Quite the opposite, they are really very good. Coverage of the DCI-P3 film colour gamut at 97% and 71% for the wider BT.2020 palette is still high-end. We just have to honestly admit that those few percentage points of coverage advantage lie with QD-OLED technology and may be noticeable in very specific moments.

Like every Philips TV we've tested, the MLED920 was primarily assessed in Filmmaker mode – the so-called "most honest" mode, designed for films and to faithfully convey the intentions of the creators. Indeed, in terms of colour accuracy, it performs best among all the modes available on the TV, but it is not without flaws. The first thing that stands out is the white balance. The image has a slight tendency towards purple-pink tones, giving it a somewhat unnatural character. However, an even bigger problem turned out to be what we mentioned earlier – image clipping. Just looking at the gamma or EOTF charts reveals that the line deviates significantly from the norm, dropping below a value of 1.8. In practice, this means "bleeding" of 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, image quality can be significantly improved.

When it comes to factory colour reproduction, our test unit in SDR mode suffered from a slight deficit in red and yellow. This resulted in a subtle yellowish tint visible in shades of white. However, this is not the biggest issue with the S85F. Similar to the QD-OLED panel variant, the main problem with this model is the way it presents HDR content. When we look at the EOTF curve graph, it’s easy to see that the TV has quite significant issues with strong image over-brightening. This results in the final image becoming very unnatural in many scenes.

After calibration, we managed to largely tame the white balance – to the extent that the average viewer will not be able to detect colour inaccuracies. The characteristic pink-purple glow that previously disrupted the naturalness of the image has also disappeared. The colour palette has been organised, and the colours appear more cohesive and neutral. The gamma in SDR content looks really good after calibration – there’s no sign of the earlier “bleeding” effect in bright scenes. The image has become more contrasty and free from the milky effect that previously severely affected the viewing experience. In the case of HDR content, the improvement is also noticeable, although here it is still evident that the television goes “its own way”. The EOTF curve cannot be fully adjusted, as Philips simply does not offer tools for precise control of this parameter in its settings. In many films, the television still exposes the image “in its own way”. Despite these limitations, calibration has brought a lot of good – the majority of colour inaccuracies have been minimised and the overall image balance has significantly improved. However, one must remember that certain barriers arise from the very hardware construction and simply cannot be overcome.

After conducting calibration in Filmmaker mode, we managed to eliminate most unwanted effects. In SDR content, the TV performs exceptionally well, and its colour reproduction errors do not exceed a value of 2, which is an outstanding result. The HDR content looks a bit worse, though still very good. Although we managed to eliminate a significant unnaturalness of the image caused by an overly high EOTF curve, the most discerning observers may notice that it is not perfectly aligned. It runs slightly below the reference curve, which would suggest that the S85F has minor issues in displaying all details in the image. We must immediately point out that it is highly unlikely for the average viewer to notice any deficiencies in the picture. We assess the final result after calibration as exemplary.

The manufacturer has equipped this model with several features that improve signal quality, and although we usually approach such “enhancers” with caution, here they prove to be really helpful. The key option is called “distortion reduction” – it works best at a medium level because, on one hand, it effectively smooths out unwanted steps and colour transitions, and on the other, it doesn’t excessively cut details, meaning the image still looks natural.

It’s a bit worse when it comes to upscaling. Lower quality materials – such as the test video with the model – appeared soft and lacking sharpness. Of course, it can be partially adjusted with the sharpness slider in the menu, but the result still falls short compared to what competitors offer at a similar price. Philips still needs to work on this aspect because, in light of the successful improvement of tonal transitions, the upscaling simply comes off weak.

The processing of tonal transitions (gradients) in the S85F is at a high level. The television effectively handles posterization (the "stepping" effect of colours), even with heavily compressed content, for example, from streaming services. However, using this feature requires a certain compromise. We noticed that the noise reduction algorithm is quite aggressive – even at the lowest setting, it can eliminate the natural film grain, which for many viewers is part of the film's aesthetics. The "Standard" setting seems to be a golden mean, without causing a noticeable loss of important details, so we can recommend it. However, we advise against using the "High" level, which, in addition to noise, also removes desired details such as texture or the structure of objects on the screen.

The upscaling process of lower resolution content works very well in the S85F. The image is sharp and clear. The only minor imperfection we managed to observe is occasional slight aliasing on the edges. The television still displays characteristics typical of this manufacturer, namely active "overscan" (a slight image enlargement). This should be kept in mind, especially when watching older content, as it may result in minimal clipping of the original frame.

Philips MLED920 features a 144 Hz panel, which immediately suggests that we shouldn’t complain about motion smoothness. And indeed – for a VA panel, the motion blur is relatively low here, and while you can sometimes notice slight issues on darker backgrounds, they’re not something that will catch the eye of most people during regular viewing.

A big plus is also 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 character of the image, they can increase the sliders, and if they want to maintain the natural “judders” of a cinematic frame, they just need to set lower values. This way, everyone can find a happy medium.

S85F is a model with impressive speed. The use of a 120 Hz OLED panel ensures that dynamic scenes, both in games and during sports broadcasts, perform as expected: smoothly, sharply, and without loss of clarity. A key role here is played by the lightning-fast pixel response time, which is a natural advantage of OLED technology. Transitions between frames are instantaneous, and the image remains clear even during the fastest camera movements. Moving objects, like a ball on the field or a car in a chase scene, are clear and free from the characteristic smearing of LCD panels (so-called "trail").

For gamers, the Philips MLED920 is truly a complete tool. The manufacturer has taken care of everything that is now considered standard in televisions for consoles and PCs. It has ALLM, so the console automatically switches the screen to game mode, there’s VRR and a 144 Hz refresh rate that ensures smooth gameplay even in fast-paced titles. All key HDR formats are supported – including HGiG and Dolby Vision Gaming for Xbox – which means that regardless of what you’re playing and on which console, the television will be able to extract the maximum potential from the image. In everyday gaming, the Game Bar proves useful too – a relatively simple implementation by Philips, but a functional panel where you can quickly check image parameters, enable VRR, or adjust details without leaving the game. It’s not as elaborate as the competition, but it does its job without any complaints. And finally, something that sets Philips apart from the competition – Ambilight. The three-sided LED backlighting can make a huge impression in games, especially in the evening. It’s also a way to slightly 'expand' the screen and create a greater sense of immersion. And since coloured LEDs have recently become almost an essential element of a gamer’s room, the MLED920 fits perfectly into this trend.

The 85F has practically everything on board to become the dream screen for gaming. Onboard, we find four full-fledged HDMI 2.1 ports with a bandwidth of 48 Gb/s, support for VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). Additionally, there's a super-detailed Game Bar that clearly displays all key parameters. However, the real gem is the Game Motion Plus feature. It's a motion smoother dedicated to games that makes the animation more pleasing to the eye while only slightly increasing input lag. This is a rare and well-functioning combination, for which Samsung deserves a lot of applause.

And now for the moment where we have to vent a little. The lack of Dolby Vision in Samsung TVs has become standard, so there's no point in holding out hope (unless something changes in the future). Unfortunately, it's much harder to explain the disappearance of support for HGiG after one of the software updates. HGiG (HDR Gaming Interest Group) is a key mode that allows for precise brightness reproduction in HDR games, according to the creators' intentions. Without it, HDR calibration on the console becomes less precise, which can leave us with an image that's too dark in the shadows or excessively bright in the light areas. Hopefully, Samsung will fix this in the next update – we have high hopes for that. Because if HGiG returns, the S85F will become almost the perfect TV for gamers.
