Samsung QN85F vs Samsung S85F (WOLED)

Although more than twice the number of dimming zones compared to its predecessor did not translate into a spectacular jump in black levels and contrast, we definitely felt it in the HDR effect itself. The QN85F is up to 50% brighter than last year's model, making a huge impression in dynamic scenes. The peak brightness can reach almost 1700–1800 nits, which is truly impressive for Mini-LED in this class. The best part is that almost regardless of the scene being watched, the HDR effect remains strong and vibrant. In four out of five test scenes, brightness was maintained around 1000 nits, a level that in most cases allows the viewer to experience the true magic of this format. Of course, in scene number 4 from the film Sicario 2, the limitations of Mini-LED technology become apparent – the brightness of the helicopter’s small light drops to around 500 nits. This result is not stellar, but it is still much more acceptable than last year's model. Samsung therefore deserves applause, as the improvement in brightness in the QN85F is drastic compared to its predecessor. However, it is a shame about a certain trend visible in this year's televisions – the manufacturer has worsened the colour gamut coverage. Although the QN85F has a QLED panel, its score of around 90% DCI-P3 is average, and in the most demanding films, it can lead to less vibrant colours than its predecessor. Despite this shortcoming, the overall HDR effect stands at an excellent level and truly makes a big impression in this class of devices.

For the majority of the time, let's say in 90% of film scenes, viewers will see virtually no difference between the versions of the S85F. When small, but very bright light points appear on the screen – a lantern in a dark alley, an explosion, the sun breaking through the clouds – this WOLED panel (similar to the smaller S85F) performs exceptionally well. Our measurements indicated a peak brightness of around 750 nits. We can state with full confidence: 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 must light up at full power brightly. Examples include a scene with a white background, a skiing scene, or our test sequences (5) from the film The Meg. And here, unfortunately, the results diverge significantly to the detriment of the variant with the WOLED panel. Our measurement equipment was able to register a maximum brightness of around 250 to 300 nits in such conditions. To be clear: the same model with a QD-OLED panel in the same test is nearly twice as bright. The second matter: colours. And here, we also have to be honest – QD-OLED has a structural advantage. Why? It's simple. QD-OLED generates colours from three components (red, green, and blue) and does not require an additional white subpixel. The WOLED panel we are testing here uses that white subpixel mainly to boost overall brightness. The effect is that QD-OLED is able to show a slightly wider colour palette and the colours are somewhat "purer". But to be clear: it's not that the colours on this WOLED panel are bad! On the contrary, they are really very good. The coverage of the DCI-P3 film palette at 97% and 71% for the broader BT.2020 palette is still high-end. We just need to honestly admit that this few percentage points of advantage in colour coverage lies with QD-OLED technology and may be noticeable in very specific moments.

Samsung QN85F offers several preset picture modes, but by default, when the television is turned on, it starts in "Eco" mode. And we could actually end the discussion here, because for such a model, using this setting makes no sense – the picture is washed out, unpleasant, and far from what we expect from a television of this class. We therefore carried out our tests in the best of the available modes, which is the Filmmaker mode. Its purpose is to faithfully reproduce what the directors saw during the filming of the movies, and indeed this is the setting that performs best among all factory options. However, this does not mean that it is without flaws.

Both in SDR and HDR, the QN85F quite strongly emphasised warm colours. This resulted from deficiencies in white balance, where there was a distinct lack of blue. Additionally, the picture was sometimes overexposed – as indicated by both the gamma brightness characteristic and the EOTF curve, which showed that the television tends to blow out scenes. In SDR, the colour reproduction errors (Delta E levels of 4-5) were still acceptable, but in HDR the discrepancies became quite large and clearly deviated from what the creators intended to show us. Fortunately, Samsung provides a wide range of calibration tools in its televisions, so – as always – we proceeded with professional calibration to see how much could be improved.

When it comes to factory colour reproduction, our test sample in SDR mode suffered from a slight deficit of red and yellow colours. This resulted in a faint yellowish tint visible in shades of white. However, this is not the biggest problem with the S85F. As with the variant with a QD-OLED panel, the main issue with this model is the way it presents HDR content. When we look at the EOTF curve chart, it is easy to see that the television has quite significant problems with strong image clipping. Such behaviour causes the final image in many scenes to become very unnatural.

After calibrating the film mode, we managed to tame the colours in both modes to near perfection – most of them did not exceed an error value of 3, which is the threshold of perception by the human eye. The image became more natural, fuller, and at the same time free from bloom, which was noticeable right after taking the television out of the box. This shows the great potential of the QN85F and how well it responds to precise settings. However, this does not change the fact that certain technological barriers cannot be overcome. Despite the enormous benefits of calibration, there are still limitations of the panel itself. Although the number of dimming zones has doubled compared to its predecessor, the algorithms controlling the backlighting can manipulate brightness in their own way. Sometimes this leads to slight colour inaccuracies or gently visible halo effects around bright objects. Nevertheless, the experience after calibration is truly pleasant and demonstrates how good a screen the QN85F can be if we just take a moment for proper settings.

After conducting calibration in Filmmaker mode, we managed to eliminate most of the unwanted effects. In SDR content, the television performs excellently, with its colour reproduction errors not exceeding a value of 2, which is an outstanding result. HDR content looks slightly worse, though still very good. Although we were able to eliminate the significant unnaturalness of the image caused by the excessively 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 difficulties in showcasing all the details in the image. We must emphasise here that it is very unlikely that the average viewer will notice any shortcomings in the image. The final effect after calibration is evaluated as exemplary.

Although the native tonal transitions on the QN85F with 4K material perform excellently, we do not always deal with content in the highest resolution. At that point, it becomes crucial how the television handles upscaling and digital image processing. This process is managed by Samsung's proprietary processor – AI NQ4 Gen2. In practice, it operates very efficiently. If visible colour banding or other undesirable phenomena occur on the screen, for instance, in materials from YouTube, they can easily be smoothed out using the "noise reduction" feature. Set to a medium level, it improves tonal transitions without excessively blurring desired details. However, it is important to remember that – as with most Samsung televisions – this function heavily interferes with the film grain. Therefore, during cinematic screenings, it is wise to use it cautiously to avoid losing the natural character of the image.

The upscaling itself looks very good. Test materials in lower resolutions were displayed sharply and clearly, with a great deal of detail. The only downside remains the issue of overscan, which is the trimming of the edges of the screen. In most situations, this is not noticeable, but with very old materials below HD quality, there may be cases where a fragment of the image from the left side gets slightly cut off.

The processing of tonal transitions (gradients) in the S85F is at a high level. The television effectively handles posterisation (the "banding" effect of colours), even with heavily compressed content, e.g., 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 natural film grain, which for many viewers is part of the film's aesthetics. The "Standard" setting seems to be a happy medium, not causing a noticeable loss of important details, which is why we can recommend it. However, we advise against using the "High" level, which, in addition to noise, also removes desirable details such as texture or structure of objects on the screen.

The upscaling process of lower resolution content works very well in the S85F. The image is sharpened and clear. The only minor imperfection we managed to observe is occasional, subtle aliasing on the edges. The television still exhibits characteristics typical of this manufacturer, namely active "overscan" (slight image enlargement). It is worth keeping this in mind, especially when watching older content, as it may result in minimal clipping of the original frame.

Motion smoothing and fluidity in the QN85F is a topic worth discussing in more detail, as the television is equipped not with a standard 120 Hz panel, but with a 144 Hz one. The extra hertz will mainly be appreciated by PC gamers, but the mere presence of such an option can be seen as a nice addition and a sign of the times – it’s hard to complain about the trend towards faster panels, as in practice, each of us would prefer the image to be as smooth as possible. However, the most important thing is how the television handles typical 120 Hz refresh rates – in the case of consoles, sports, or films recorded at 24 or 30 frames per second. Here, the QN85F performs really well. In films, one can easily adjust the character of the image thanks to the "image clarity" function, where we find two adjustable sliders. Key for screenings is the one responsible for reducing judder. Lower values give the image a more cinematic character with preserved "frame rate," while higher values lead to strong smoothing reminiscent of television theatre.

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, meet expectations: smoothly, sharply, and without loss of clarity. A key role here is played by the instant response time of the pixels, which is a natural advantage of OLED technology. Frame transitions are instantaneous, and the image remains clear even during the fastest camera movements. Moving objects, such as a ball on the pitch or a car in a chase scene, are clear and devoid of the characteristic motion blur associated with LCD panels (the so-called "ghosting").

The Samsung QN85F makes a really great impression in terms of gaming features. It has four HDMI 2.1 ports, so we can easily connect multiple devices simultaneously. There is also variable refresh rate (VRR) which prevents screen tearing, as well as an automatic game mode (ALLM) that allows the television to switch to the appropriate settings when we start the console. Additionally, it supports refresh rates of up to 144 Hz – something that PC gamers will particularly appreciate, but the mere fact that such an option is available shows that Samsung is fully committed to supporting gamers. The Game Bar panel also deserves praise. It provides a quick overview of the most important parameters – from frame rate to refresh mode, even including shortcuts to picture settings. Instead of navigating through the entire menu, everything is at hand, which proves to be very convenient in practice. However, the most interesting addition is the Motion Plus gaming feature. It's effectively a motion smoother adapted for the gaming world. When enabled, the image becomes smoother, sometimes looking as if we've gained several extra frames, and importantly – the response time doesn’t increase enough to hinder gameplay. This solution truly sets Samsung's 120Hz televisions apart from competitors.

[UPDATE] We have updated our tests of Samsung televisions from the 2025 model year due to the release of software version 1131, which restored the crucial gaming feature HGiG.

The only major downside remains the lack of proper HGiG support. This is a standard responsible for correct tone mapping in HDR games, meaning that brightness and contrast are displayed as intended by the creators. Without HGiG, we have to adjust brightness manually, which doesn’t always yield perfect results. The feature was available in previous models, but it vanished from the QN85F after one of the updates. We hope that Samsung will quickly resolve this issue, and we will keep checking to see if it has been fixed.

The 85F has practically everything on board to become the dream screen for gaming. It features 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, which clearly displays all the key parameters. However, the real gem is the Game Motion Plus feature. This motion smoother dedicated to games makes animations more pleasant to the eye while only slightly increasing input lag. This is a rare and well-working combination, for which Samsung deserves great applause.

Now for the moment where we have to complain a bit. The lack of Dolby Vision in Samsung TVs is already a 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 representation in HDR games, according to the creators' intent. Without it, HDR calibration on consoles becomes less precise, potentially leaving us with images that are too dark in the shadows or excessively blown out in the bright areas. Perhaps Samsung will fix this in the next update – we have high hopes for that. Because if HGiG returns, the S85F will become nearly the perfect TV for gamers.

[UPDATE] We have updated our tests of Samsung TVs from the 2025 model year due to the release of software version 1131, which has restored the HGiG feature essential for gamers.
