Philips OLED770 vs Samsung S85H

The Philips OLED770 does not attempt to compete with the brightest OLEDs on the market, and it would be difficult to expect that, as it is the entry-level model in Philips' range for 2025. In our measurements, it reached a maximum of around 700 nits, which allows enjoyment of HDR effects in scenes where light appears sporadically – for example, in the flash of headlights or a starry sky. In such moments, the image can truly be stunning. However, it is different when there are more bright elements on the screen. The television, like many cheaper OLEDs, limits luminance in those situations, causing the entire image to noticeably dim. This was best observed in a scene from the film The Meg, where the sun comes out behind an oil rig – the brightness then dropped to around 250 nits, which is almost three times less. The HDR effect remains pleasant to the eye, but it is worth being aware that this model performs best in scenes with less intense light. Fortunately, the OLED770 has a trump card – the coverage of the DCI-P3 colour gamut is as high as 99%, so colours in films and games are vivid and very close to what the creator intended to convey.

Interestingly, the new WOLED SE panel has brought a slight improvement in brightness to the S85 series. In the same movie scenes last year's model stayed closer to around 700 nits, while the S85H can reach roughly 800 nits. This isn't a change that completely transforms HDR perception, but that extra brightness is noticeable, especially with pinpoint highlights, specular reflections and stronger special effects. Around 800 nits is already a very good result for an entry-level OLED and in most films it's enough for HDR to have the proper impact. Bright elements can stand out clearly against perfect black, and it's still that contrast that does most of the work. You do need to bear in mind a typical limitation of organic panel technology. When a very bright scene covers a large part of the screen, brightness can drop by almost half. That's the effect of the panel's protection mechanisms, which limit its power with large bright areas.

Colours

The S85H can deliver very pleasing, saturated colours and in most HDR films it looks really good in that respect. We measured around 95% DCI-P3 coverage, so the palette most commonly used in movies is reproduced to a very high degree. Skin tones, greens and stronger reds still have the right intensity, and in normal viewing it's hard to fault them. Only when you look wider at BT.2020 do the limitations of the new OLED SE panel become apparent. Coverage was about 70%, a little less than previous-generation WOLEDs and noticeably less than QD-OLED panels. In films this is not a big loss, because most productions rarely use such highly saturated colours. You're more likely to notice it in games, where creators often opt for more intense colours.

The first measurements already show that the factory settings of the Philips OLED770 have quite a lot to improve even in Filmmaker mode. The white balance chart clearly shows a lack of blue, resulting in a slightly yellowish tint to the image. In practice, the white is not snowy but leans towards warmer tones – which some may even appreciate, but from the perspective of accuracy, this is a deviation from the norm. The gamma, on the other hand, tends to the darker side – the average value is around 2.6 instead of the reference 2.4. In the midtones, the image appears subdued and more saturated, which may seem too "filmic," but detracts somewhat from naturalness. However, the most issues are evident in colour reproduction. The average error is relatively high, and some colours – particularly shades of grey – deviate significantly from what one should see. In everyday viewing, this means that sometimes colours may look less natural than we would like.

For colour evaluation we naturally chose Filmmaker mode, and in SDR our S85H sample was very well set up from the factory. The largest deviation is in the white balance, where, as brightness rises, there is a slight lack of blue. In practice this means whites and greys have a subtly warmer tint than they should. However, this is not a major fault and during normal viewing it is unlikely to be very noticeable. Gamma also stays close to the reference value, so the image is neither overly bright nor unnecessarily dim. The S85H’s SDR picture quality is therefore very good straight out of the box. A few more imperfections appear in HDR. Here the white balance drifts more with increasing brightness, blue starts to dominate and the red component is clearly lacking. This also translates into larger errors for some colours. They do not yet amount to shifts that completely change the character of the image, but in direct comparison with a reference the difference is easier to spot. Overall, Filmmaker mode is a very good starting point before professional calibration.

The Philips OLED770 from the outset signalled that it harboured significant potential, but in its factory settings, it was difficult to see this fully. The picture was often too warm, and some colours appeared to have lost their naturalness along the way. Calibration, however, revealed that it is a very responsive television – it reacted to every adjustment and almost immediately unveiled another layer of its capabilities. The white balance could be set in both SDR and HDR to eliminate the yellowish tint and introduce a neutral, clear white. The gamma stabilised closer to perfection, allowing midtones to regain their naturalness, and shadows stopped being artificially darkened, perhaps even with a slight brightening effect. The result was obvious... Films were watched with greater ease; the picture had cinematic depth, but without the feeling that something was exaggeratedly darkened. However, the most interesting aspect was the work on colours. Factory errors were not dramatic but slightly noticeable – skin tones were sometimes too warm, and grey didn’t always have the shade we expected. After calibration, the error values dropped to around 2, and in many cases even below 1. This is certainly a level lower than the threshold of human perception. In other words, after correction, the colours finally "clicked" into place. Looking at the screen, we had the impression that the television had begun to speak with its full voice. Like an instrument that has finally been well tuned.

Calibration yields very good results on the S85H. First and foremost, it was possible to set the white balance almost perfectly, which removes the slightly too warm character of the image that was previously visible in SDR. Colour reproduction itself also improves markedly, with most errors falling to a very low level and in everyday viewing it is hard to speak of any noticeable inaccuracies. You can also make significant improvements in HDR, although some issues remain due to the TV's inherent characteristics. The S85H does not always hold the brightness curve perfectly; the darkest parts are slightly lifted, and as you approach the panel's limits small deviations are visible in the brightest areas. Added to this is the limited coverage of the wider BT.2020 gamut, which of course cannot be overcome by any calibration. Despite this, the end result is very good and, after calibration, the S85H can produce a really well-tuned, natural image.

The issue of the aforementioned colour banding can largely be mitigated thanks to the 'distortion reduction' feature, which is an algorithm for smoothing tonal transitions in Philips. It performs best at a low setting – effectively eliminating unwanted colour bands while not introducing strange artefacts or losing image detail. This is one of those features that is truly worth leaving switched on.

The situation is somewhat worse regarding upscaling. The image from a lower resolution can be too soft, while in some areas, characteristic 'jaggies' appear. The impression is that the algorithm is trying to reconcile two conflicting directions – smoothing and sharpening – and ultimately fails to find a happy medium. As a consolation, it can be added that the television has no issues with overscan, meaning it does not cut off the edges of the image, which sometimes occurs in other competing models.

Samsung has fitted the S85H with the same proprietary AI NQ4 Gen2 processor used in 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 does not feel overly artificial. One caveat is a typical Samsung trait: at very low resolutions you cannot completely disable overscan, so the TV may slightly crop the left edge of the image. The "noise reduction" function also works very well, smoothing weaker tonal transitions. The processor can effectively remove posterisation and other imperfections visible in lower-quality material. However, you need to be careful with the strength of this function, because Samsung can be quite aggressive here. When it is activated, small image details, such as the texture of skin or clothing, can start to disappear along with the unwanted artefacts.

The issue of the matrix 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. That sounds like great news – after all, 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 ghosting or blurring, making it perfect for both dynamic games and sports broadcasts. The problem only arises at 144 Hz. Unlike models with official support for this frequency, here you can observe the phenomenon known as frame skipping. This means that the television cannot display all the frames – some are skipped, causing motion to lose smoothness, and double contours appear on the screen. The effect resembles the operation of the BFI function, which Philips does not offer in this model anyway.

The S85H uses an OLED panel, so it performs excellently for motion blur. Pixels respond virtually instantly, so moving objects do not leave the characteristic trailing seen on some LCD TVs. This is especially noticeable in sport and fast-paced games, where the picture remains very clean even during rapid motion. The panel itself runs at 120 Hz. That is more than sufficient for films, TV series, sport and console gaming. It is a pity Samsung did not 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 does not affect motion handling in films or sport.

You also have a classic motion-smoothing feature with two settings, blur reduction and judder reduction. So you can decide whether films should retain their cinematic 24 frames per second or whether you prefer to smooth them a little. The S85H gives plenty of freedom here, and the interpolation works well and, with sensible settings, does not generate too many artefacts.

If someone is looking for a television for gaming, the Philips OLED770 is a contender that is hard to ignore. The mere fact that we have an OLED here provides an excellent starting point – perfect black and infinite contrast make evening sessions in atmospheric games look as if they were lifted straight from the cinema. On top of that, there is the Ambilight system, which consists of LEDs on the back of the television that extend the image onto the wall behind the screen. The effect is such that even playing FIFA can look like a small spectacle, and in horror games the atmosphere becomes truly thick. From a technical standpoint, 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 if someone is using an Xbox Series X, they can also count on Dolby Vision support in games. One must only know that in this mode the input lag is slightly higher than standard, though still at an acceptable level. As a bonus, we get the “Game Bar” panel, which is a special tool bar for gamers. It isn’t the most conveniently designed solution, but it allows you to check key parameters without leaving the game. Overall, this results in a television that, on one hand, has all the essential gaming features, and on the other, can add something unique – Ambilight. And it is this mix of technology and visual effect that makes the OLED770 one of the better screens for gaming at home.

The Samsung S85H is very well prepared for gaming, essentially regardless of whether you connect a console or a PC. The manufacturer hasn't skimped on ports 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 your console is plugged into. With multiple devices that matters a lot, because you don't have to choose between a console, a PC or a soundbar connected via eARC. The feature set itself is very comprehensive. The S85H supports VRR, FreeSync and automatic game mode switching, and Samsung also offers its extensive Game Bar where you can quickly check key signal parameters and change settings without leaving the game. The only notable omission is Dolby Vision, which will matter mainly to Xbox owners. This, incidentally, is typical of Samsung TVs. Game Motion Plus performs very well, and it's one of the features that have set Samsung TVs apart for years. It smooths motion in games running at 30 or 60 fps, but does so without as much increase in input lag as a conventional motion interpolator. In practice, with slower-paced games, racing titles or action games this can really improve the perceived motion, especially if you're sensitive to low frame rates.
