SAMSUNG QN80F vs Philips OLED770

QN80F is quite a bright screen – in synthetic tests, it reached nearly 1000 nits, which allows for reasonable expectations of HDR content. And indeed, in many scenes, the TV can truly shine. Sequences with a lot of light – like shots from the movie Life of Pi or wide, bright surfaces in The Meg – look impressive. Brightness stays around 700 nits, which provides a solid effect, enough to feel the true "HDR magic." Unfortunately, not every scene looks this good. In content with small, bright details on a dark background, like in Sicario 2, the TV can struggle – it can significantly dim individual elements, sometimes to the point where they disappear from the image. This is a result of the limited number of dimming zones, forcing the device into compromises: either stick to inky blacks or sacrifice some detail. QN80F usually chooses the former. As a consolation, it offers quite decent coverage of a wide color palette – DCI-P3 at 93%. It's not the highest score on the market, but it's more than enough for most content on streaming platforms.

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.

We always test TVs in the best available factory mode – for the Samsung QN80F, this is the Filmmaker mode, and indeed, it provides the settings closest to the creators' intentions. However, this doesn’t mean everything looks perfect. In SDR content, the biggest issue was an unbalanced white balance – slight deficiencies in green and a noticeable excess of red led to noticeable colour errors, and one could say the screen had a pinkish hue. This was clearly visible in the colour checker test, where colours “escaped” outside their target fields – to such an extent that a sensitive viewer's eye could catch it even without the help of a meter.

In HDR content, the white balance was much better, but another issue arose – brightness management. The EOTF curve caused an overly bright image most of the time, which affected the perception of contrast and made the screen slightly “flicker” during dynamic changes in light. We’ve already discussed this in the paragraphs about black levels and HDR. Fortunately, Samsung offers users plenty of options. The QN80F features a rich set of calibration options, including a 20-point white balance – which is why we decided to check what this TV is really capable of after a proper calibration.

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 conducting a thorough calibration, it was possible to bring most image parameters to a really good level. The white balance in both SDR and HDR presents itself almost perfectly – the image is natural, neutral, and free from the previously noticeable redness. Colours have gained depth, and the overall visual experience has become more pleasant and cohesive. It was also possible to partially manage brightness, which in the factory version could cause issues. The EOTF chart shows that the television performs much better with brightness after calibration – there is no longer excessive dimming of certain elements. In films, it can still be noticed that the QN80F has a tendency to slightly brighten the smallest bright details – this is already a consequence of the device's construction and the limited number of dimming zones. In short: not everything can be overcome, but what was possible has been improved. After calibration, the QN80F makes a really good impression, looking simply more mature and professional.

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.

If you notice strange colour transitions or unwanted artefacts while watching lower quality materials – for example from YouTube – it's worth checking the settings and enabling the noise reduction feature. In our opinion, the best setting is at the 'medium' level – it effectively smooths out problematic colour transitions without overly blurring the entire image. However, it's important to know one thing: this option tends to remove film grain. If someone values preserving that effect (e.g., in older films), it's better to simply turn it off – regardless of the level, the grain always disappears.

Regarding resolution scaling (also known as upscaling), Samsung – as usual – performs very well in this area. The QN80F doesn't quite match the top models costing tens of thousands, but for its price class, it performs impressively. Materials of very poor quality (e.g., from SD television or older video files) are noticeably improved and look surprisingly decent. The only noticeable downside is the typical Samsung issue with overscan – which is a slight cropping of the image edges at very low resolutions, such as 576p.

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.

QN80F is truly a “fast” TV. The panel used offers a refresh rate of up to 144 Hz, which in practice means that the screen keeps up with the action – whether we’re watching a movie, playing games, or browsing dynamic content online. The image doesn’t stutter, isn’t overly blurred, and everything simply looks smooth and pleasing to the eye. Of course, the manufacturer hasn’t forgotten about cinema fans – in the settings, we find an option to adjust motion smoothness, allowing us to tailor the effect to our own preferences. You can leave a more “frame-y” look (for those who enjoy the classic film vibe) or crank up the smoothness to a higher level to achieve a theatrical smoothing effect. Importantly, the choice is ours. Watching movies and playing on the QN80F is just plain fun.

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.

Samsung QN80F is a TV that delivers on almost every front when it comes to gaming. We have a 144 Hz panel, four fully-fledged HDMI 2.1 ports, support for gamers in the form of variable refresh rate (VRR), auto low latency mode (ALLM), and even one of the best-designed game bars on the market. The cherry on top is the motion smoother, which – as the only one in the world – works in games without significantly increasing input lag. Sounds like an almost perfect TV for gamers? And indeed, it’s almost that.

As usual, Samsung does not support Dolby Vision in gaming, but that’s no surprise anymore. However, what is much more surprising is that... the HGIG feature has disappeared – which is a system that allows a console (e.g. PlayStation 5 or Xbox Series X) to precisely match HDR tone mapping to the capabilities of the TV. In the latest firmware update for the 2025 models, this option simply vanished. It looks more like a bug than a deliberate move, but it must be honestly noted that as of the writing of this review, the HGIG feature is simply absent.

And it’s this one missing feature that turns the QN80F from an almost perfect gaming TV into a “nearly” perfect device. It’s a pity – because everything else indicated that Samsung could once again set the bar very high in this generation.

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.
