Samsung Neo QLED QN85D / QNX1D vs Philips OLED770

Samsung QN85D leaves us with mixed feelings regarding HDR quality. It can shine in synthetic luminance tests, reaching even 1000 nits – which makes scenes like those from 'The Meg' or the start of 'Life of Pi', where the screen is all bright, look truly impressive. However, in practice, the device has its limitations – especially when smaller bright elements appear on the screen. In such moments, brightness noticeably drops, and the HDR effect loses its punch. At brightness levels around 200-300 nits, the magic of HDR simply fades away, not delivering spectacular effects. However, it’s not that the television completely disappoints – coverage of the DCI-P3 colour gamut at 95% is quite decent, although it doesn’t stand out against the best competitors. Colours are well-rendered, but it's clear that HDR could make a bigger impression if brightness could be better controlled.

The Philips OLED770 doesn't try to compete with the brightest OLEDs on the market, and it's actually hard to expect that, as it's the entry-level model in Philips' range for 2025. In our measurements, it reached a maximum of around 700 nits, which allows for enjoyment of HDR effects in scenes where light appears in spots – for instance, in the flash of headlights or a starry sky. In such moments, the picture can truly amaze. However, it's different when there are more bright elements on the screen. The TV, like many cheaper OLEDs, restricts luminance at that point, and the entire image noticeably dims. This was best seen in a scene from the movie The Meg, where the sun rises behind an oil platform – the brightness dropped to around 250 nits, which is almost three times less. The HDR effect remains pleasing to the eye, but it's worth being aware that this model performs best in scenes with less intense light. Fortunately, the OLED770 also has an ace up its sleeve – the coverage of the DCI-P3 colour palette is as high as 99%, so colours in movies and games are vibrant and very close to what the creator intended.

Samsung QN85D TV has been tested in the best available mode – Filmmaker. While one might expect its name suggests a mode perfectly suited for films, unfortunately, it has several significant issues.

When it comes to white balance for HD content, there is a noticeable dominance of red and blue, which makes the entire image take on pinkish hues – this is also confirmed by Colour Checker tests. This effect disturbs the naturalness of skin tones and many other elements, which is particularly evident in more demanding scenes. Initially, the white balance for 4K HDR content seems correct, but at the end of the graph, there is a significant spike in blue hues, affecting the final image quality and making the colours appear unnatural.

The gamma brightness characteristic is also not ideal – although it generally stays close to the reference value, there is a slight drop below 2.4, which can impact the perceived depth of shadows. The EOTF curve responsible for 4K content does not perform any better. There is a clear boost compared to the reference curve, leading to excessive brightness in some areas, thus losing the cinematic quality that the Filmmaker mode should provide. While it might initially seem that the effect is cinematic, unfortunately, the number of errors in colour and brightness reproduction is too significant to call it flawless.

The first measurements already show that the factory settings of the Philips OLED770 have a lot to improve, even in Filmmaker mode. The white balance chart clearly indicates a lack of blue, giving the image a slightly yellowish tint. In practice, white is not snow-like, but leans towards warmer hues – which some may even find appealing, but from a precision standpoint, this is a deviation from the norm. The gamma, on the other hand, tends to be on the darker side – the average value is around 2.6 instead of the reference 2.4. In mid-tones, the image appears muted and more saturated, which can look too "cinematic" but detracts a bit from the naturalness. However, the most significant issues are visible in colour reproduction. The average error is relatively high, and some colours – particularly shades of grey – deviate significantly from what should be seen. In everyday viewing, this means that sometimes colours may look less natural than we would wish.

After professional calibration of the Filmmaker mode on the Samsung QN85D television, a significant improvement is noticeable, especially for HD/SDR content. The white balance has been completely free of major errors, and the brightness characteristics for this type of content have been significantly adjusted, allowing for a more natural and realistic image. Television, YouTube films, and other HD materials now look much better, with appropriately balanced colours and without the exaggerated hues that previously marred the experience.

However, the biggest issues arise with 4K HDR content. Despite the calibration, it's hard to speak of significant improvement in white balance here – the differences are cosmetic rather than essential. Brightness, governed by the EOTF curve, seems to be set according to the reference level in synthetic tests at first glance, but has its limitations during actual viewing in films. When analysing the EOTF curve in real film scenes, it becomes clear that the television struggles to maintain consistency in brightness. The effect is that mixed scenes still have their darkest elements boosted, leading to exaggerated contrasts, and completely dark scenes remain too dark, which negatively affects the visibility of details.

Philips OLED770 had shown signs from the start that it harboured significant potential, but it was hard to fully appreciate this in its factory settings. The image was often too warm, and some colours appeared as if they had lost their naturalness along the way. Calibration revealed that this television was very amenable to work – it responded to every adjustment and almost immediately unveiled another layer of its capabilities. The white balance was set in both SDR and HDR so that the yellowish haze disappeared and a neutral, clear white emerged. Gamma stabilised closer to perfection, which helped restore the naturalness of mid-tones, while shadows ceased to be artificially darkened, perhaps even with a slight brightening effect. The result was obvious... Movies are watched with greater ease; the image has cinematic depth without the feeling that something is overly darkened. However, the most interesting aspect was working on the colours. Factory errors were not dramatic, but slightly noticeable – skin tones could be too warm, and grey wasn’t always the shade we expected. After calibration, the error values dropped to around 2, and in many cases even below 1. This is a level that is definitely lower than the threshold of discernibility for the human eye. In other words, after correction, the colours finally “clicked” into place. Looking at the screen, we felt like the television had begun to speak with a full voice. Like an instrument that had finally been properly tuned.

When checking the fluidity of tonal transitions in low-resolution materials on the Samsung QN85D television, it’s worth noting the noise reduction feature, which significantly improves problematic tonal transitions. On the other hand, this feature also has its downsides – it removes film grain, which is an important element of many productions, giving them authenticity, and it can also soften the image. This may appeal to those who prefer a smoother picture; however, for lovers of the authentic look of films, using this feature should be considered carefully.

Regarding image scaling, the television performs very well. The model's figure is presented correctly, without noticeable distortions, and the branches in the background do not have excessive artificial sharpness, which is often a problem when scaling lower resolution materials. The high capabilities of the image processor are evident here, which can effectively process lower quality materials, ensuring good final quality.

The problem of the previously mentioned colour connections can largely be mitigated thanks to the "distortion reduction" function, which is an algorithm for smoothing tonal transitions in Philips. It works best at a low level – effectively eliminating unwanted colour bands while not introducing strange artifacts or losing image detail. This is one of those features that is truly worth keeping on.

The issue of upscaling is somewhat less impressive. Images from lower resolution can be too soft, while in some parts the characteristic "jaggies" appear. The impression is that the algorithm is trying to reconcile two contradictory directions – smoothing and sharpening – and ultimately fails to find the golden mean. As a consolation, it's worth noting that the television does not have problems with overscan, meaning it does not cut off the edges of the image, which can sometimes happen in other competing models.

Samsung QN85D TV is equipped with a 120 Hz refresh rate panel, which should satisfy both gamers and sports enthusiasts by offering a smooth and dynamic image. There are options to enhance fluidity, such as the blur and judder reduction feature, which allows precise motion fluidity adjustments on a 10-point scale. The blur reduction increases the sharpness of fast-moving objects, making action scenes more readable, while judder reduction smooths out motion, eliminating the “judder” effect. Ghosting is generally well controlled, though minor imperfections can be visible in more demanding scenes, especially when an object moves against a dark background. Additionally, the TV offers a BFI (Black Frame Insertion) feature at a 60 Hz refresh rate, which can significantly improve motion fluidity experience, although at the cost of image flicker, which might be bothersome for some users.

The issue of the panel in the Philips OLED770 is not entirely straightforward. The manufacturer claims a 120 Hz panel, but our measurements showed that the screen can accept a 4K signal even at 144 Hz. This sounds like great news – because who wouldn't want an additional mode for PC gamers at this price? However, the reality turned out to be more complex. With 120 Hz content, the television behaves like most OLEDs – the image is absolutely clear, with no trace of blurring or smearing, ideal for both dynamic games and sports broadcasts. The problem only arises at 144 Hz. Unlike models with official support for this frequency, here we see the phenomenon of so-called frame skipping. This means that the television is unable to display all the frames – some of them are skipped, causing motion to lose smoothness and double outlines to appear on the screen. The effect resembles the operation of the BFI function, which Philips does not offer in this model anyway.

The Samsung QN85D television is an excellent choice for gamers, offering a wide range of features that enhance the gaming experience and make it even more exciting. With a 120 Hz refresh rate panel, the image is incredibly smooth, which is crucial during dynamic scenes in action games. The television also boasts low input lag, allowing for nearly instant reactions to player commands, which translates into better control over characters and events on the screen.

In addition, the QN85D Samsung supports VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode) technologies, which optimise image smoothness and reduce delays by automatically adjusting the television to the needs of gamers. Moreover, the Xbox app allows for cloud gaming without the need for a console, which is a big plus for those who want to enjoy their favourite titles without additional hardware – a feature that sets Samsung televisions apart.

The Auto Motion Plus Game feature is another aspect worth highlighting. This motion smoothing technology creates the illusion of more frames per second – as a result, games at 30 fps appear smoother, resembling gameplay at 45 fps, while games at 60 Hz come closer to 90 Hz. Most importantly, this feature does not introduce significant lag, ensuring that gaming comfort is not compromised. This allows gamers to enjoy a smoother image without compromising responsiveness.

If someone is looking for a TV for gaming, the Philips OLED770 is a candidate that's hard to overlook. The mere fact that this is an OLED gives it a great starting point – perfect blacks and infinite contrast make evening sessions in atmospheric games look like they've been taken straight out of a cinema. Added to that is the Ambilight system, which uses LEDs on the back of the TV to extend the image onto the wall behind the screen. The effect is such that even just playing FIFA can look like a small spectacle, and in horror games, the atmosphere becomes really thick. On the technical side, it's also quite decent. The Philips OLED770 supports variable refresh rate (VRR) up to 120 Hz, has an automatic mode for gamers (ALLM), and for those using an Xbox Series X, Dolby Vision support in games is also available. You just need to know that in this mode, the input lag is slightly higher than standard, although still at an acceptable level. As a bonus, we also get the 'Game Bar', which is a special tool strip for gamers. It's not the most conveniently designed solution, but it allows for a quick view of key parameters without exiting the game. Overall, this gives a picture of a TV that has all the most important gaming features on one hand, and on the other can add something unique – Ambilight. And it's this mix of technology and visual effect that makes the OLED770 one of the better screens for gaming in a home environment.
