SAMSUNG QN80F vs Samsung S85F (WOLED)

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.

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.

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.

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 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.

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.

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 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.

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.

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").

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.

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.
