Philips OLED770 vs Samsung S85H

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.

Interestingly, the new WOLED SE panel has brought a slight improvement in brightness to the S85 lineup. In the same film scenes last year’s model sat closer to about 700 nits, while the S85H can reach roughly 800 nits. That’s not a change that completely transforms the HDR experience, but the extra headroom is noticeable, especially with point highlights, reflections or stronger special effects. Around 800 nits is a very good result for an entry-level OLED and in most films it’s enough for HDR to have the necessary punch. Bright elements can clearly stand out against perfect blacks, and that contrast is still doing most of the work here. However, you need to remember the typical limitation of OLED technology. When a very bright scene covers a large portion of the screen, brightness can drop to almost half. This is the result of panel protections that limit its output with large bright areas.

Colours

The S85H can deliver very pleasant, saturated colours and in most HDR films it looks really good in that regard. We measured around 95% coverage of DCI-P3, so the palette most commonly used in films is reproduced to a very high degree. Skin tones, greens and stronger reds still have appropriate intensity and under normal viewing it’s hard to have major complaints. Only when you look more broadly at BT.2020 do the limitations of the new WOLED SE panel become apparent. Coverage was about 70%, a bit less than WOLEDs of the previous generation and noticeably less than QD-OLED panels. In films this isn’t a big loss, since most productions rarely use such heavily saturated colours. You’re more likely to notice it in games, where developers more often opt for more intense colours.

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.

To evaluate colours we of course used Filmmaker mode, and in SDR our S85H unit was set very well from the factory. The largest deviation appears in the white balance, where as brightness increases it starts to lose a bit of blue. In practice this means whites and greys have a slightly warmer tint than they should. However, it's not a big fault and during normal viewing it generally isn't very noticeable. Gamma also stays close to the reference value, so the picture is neither overly bright nor unnecessarily dim. The S85H's SDR picture therefore looks really good straight out of the box. A few more imperfections appear in HDR. Here the white balance shifts more with rising brightness, with blue starting to dominate and the red component clearly lacking. This also results in larger errors in some colours. These aren't yet colour errors that completely change the character of the picture, but in direct comparison with the reference the difference is easier to spot. Overall, Filmmaker mode is a very good starting point before professional calibration.

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.

Calibration delivers really good results on the S85H. First and foremost, we were able to set the white balance almost perfectly, which removes the slightly too-warm picture tone previously seen in SDR. Colour reproduction also improves significantly, with most errors falling to very low levels, and in everyday viewing it's hard to find any visible inaccuracies. You can also improve HDR quite a bit, although some issues remain that stem from the TV's inherent characteristics. The S85H doesn't always hold the luminance curve perfectly. The darkest parts are slightly boosted, while, as you approach the panel's limits, you can see small deviations in the brightest highlights. Add to that the limited coverage of the wider BT.2020 colour gamut, which of course cannot be overcome by any calibration. Despite that, the end result is very good, and after calibration the S85H can deliver a really well-tuned, natural image.

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's S85H uses the same proprietary AI processor, AI NQ4 Gen2, as 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 doesn't come across as overly artificial. Just remember a common quirk of Samsung TVs: at very low resolutions you can't completely turn off overscan, so the TV may slightly crop the left edge of the picture. The "noise reduction" function, that is smoothing weaker tonal transitions, also works very well. The processor can effectively remove posterisation and other artefacts visible in lower-quality material. However, be careful with the strength of this function, because Samsung can be fairly aggressive here. When it's activated, along with unwanted artefacts, fine details such as skin or clothing texture also start to disappear.

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 S85H uses an OLED panel, so it performs brilliantly when it comes to motion blur. Pixels respond almost instantly, so moving objects don't produce the characteristic ghosting seen on some LCD TVs. This is especially noticeable with sport or fast-paced games, where the picture stays very clean even during rapid motion. The panel itself runs at 120 Hz. That's more than enough for movies, TV shows, sport or console gaming. It's a shame Samsung didn't 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 doesn't affect motion handling in films or sport.

There's also the classic motion smoothing feature with two settings: blur reduction and judder reduction. So you can choose whether films should keep their cinematic 24 frames per second, or whether you'd prefer to smooth them a bit. The S85H gives plenty of freedom here, and the interpolation itself works well and, with sensible settings, doesn't generate too many artefacts.

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.

Samsung S85H is very well prepared for gaming, essentially regardless of whether you connect a console or a computer. The manufacturer didn’t skimp on connectors 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 to plug your console into. With multiple devices that matters a lot, since you don’t have to choose between a console, a PC or a soundbar connected via eARC. The feature set itself is very complete. The S85H supports VRR, FreeSync and automatic switching to Game Mode, and Samsung also offers its expanded Game Bar, which lets you quickly view the key signal parameters and change settings without leaving the game. The only real omission is Dolby Vision, which will matter mainly for Xbox owners. That’s a typical trait of Samsung TVs. Game Motion Plus performs very well and it’s one of the features that has set Samsung TVs apart for years. It smooths motion in games running at 30 or 60 fps, but does so without as large an increase in input lag as a classic motion interpolator. In practice, for slower-paced games, racing or action titles it can genuinely improve motion perception, especially if you’re sensitive to low frame rates.
