Samsung S85F (WOLED) vs LG QNED80A6A (IPS)

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.

When it comes to image dynamics and brightness, the QNED80A firmly stands its ground. It is not a “bright beast” – during our measurements, peak luminance oscillated between 350-400 nits. To put it plainly: these values won't allow HDR formats to fully spread their wings. So, do not expect that the glare of the sun or car headlights in films will blind you. However, this television has a powerful ace up its sleeve that salvages the overall picture impression – and that is the colours. LG's engineers have employed an advanced filtration system (technically most likely based on PFS phosphor, marketed as QNED/NanoCell), which does a fantastic job. Thanks to this, despite average brightness, the screen is capable of generating exceptionally saturated and pure hues. Our instruments showed coverage of the wide DCI-P3 cinema colour palette at a level of 93-94%. This is a result that outclasses most standard LCD televisions. In practice, this means that when watching 4K HDR content, the picture – although not very bright – is very plastic, vivid, and delights the eye with its depth of colours.

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.

Here, regardless of whether you encounter the VA or IPS version, the situation is identical. LG engineers once again served us their vision of a "gaming look," which unfortunately has little to do with accuracy. When switched to console mode, the white balance automatically drifts towards very cold regions. The image is dominated by the colour blue, which makes it seem artificially sharpened, and the white is so aggressive that it appears burnt out. This creates an effect we associate with vibrant shop modes – everything is meant to shine and scream "I am digital." While some may appreciate this, we must say plainly: the image is not accurate. If you care about naturalness, we suggest you immediately check the settings and change the colour temperature to a warmer one.

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.

After professional calibration, the QNED80A in the IPS version has changed unrecognisably, especially with "ordinary" content (SDR). We managed to eliminate the greenish tint and calm down the overly bright gamma. In classic television or older games, colour errors (DeltaE) have dropped below the threshold of perception (value < 2). The picture is now coherent, natural, and truly pleasing to the eye. The situation is somewhat more complicated in HDR mode. Although the colours are now in place, the television has a problem with perfectly controlling the brightness (EOTF curve). Due to the limitations of edge lighting and the rather meagre adjustment options provided by LG in this respect, the television's software at times "does what it wants," just to mask the imperfections of black and contrast. However, this is not a cause for concern – despite these technical limitations, the picture after calibration is a class better than what you saw out of the box.

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.

It often happens that cheap 4K TVs mercilessly expose the flaws of low-resolution materials. Here, it is different. The QNED80A is great equipment for watching content that is not perfect. The processor does a good job of upscaling the image, making even older recordings look quite decent on a 4K screen – they are consistent and free of digital noise. Interestingly, there is a gradation reduction feature available in the settings. It is very effective in combating the so-called banding in low bitrate materials. Of course, it should be approached with some caution. Due to the lower processing power of the chip (compared to the premium series), turning on this option can sometimes result in unwanted artifacts or blurriness. Despite this risk, we encourage experimentation, as in many cases this feature can save a poor-quality viewing experience.

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").

In terms of motion reproduction, the QNED80A unfortunately has a tough time. The television is based on a display with a refresh rate of 60Hz, which is quite a disappointment for the QNED series in 2025. If you are looking for perfect sharpness during dynamic football matches, you may feel somewhat unsatisfied. A solution in this situation is the TruMotion system. It allows for artificial frame generation, which smooths out the image in films and series. In the menu, you will find a De-Judder slider – we recommend setting it to a value of 2, 3, or 4. This is the "golden mean" that improves fluidity without turning the film into a soap opera.

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.

In the gaming section, we won't be pulling the wool over your eyes – the QNED80A is not e-sports equipment. The lack of 120Hz signal support is a fact that must be accepted. However, LG's engineers have done everything possible to maximise the potential of this 60Hz panel, providing gamers with a set of desirable features. First and foremost, the television supports VRR (in the range of 48-60Hz) and ALLM. This means that the image is smooth, not choppy, and the television automatically switches to low-latency mode as soon as we pick up the controller. Accessing these options is incredibly simple thanks to the dedicated system overlay – Game Dashboard. It’s also worth appreciating the support for the HGiG format. This is a nod to owners of modern consoles. Although the screen does not support gaming Dolby Vision, HGiG ensures that the television 'understands' how to display games in HDR. As a result, we avoid the problem of blown-out clouds, which is unfortunately a plague on cheaper LCD televisions.
