Samsung S85F (WOLED) vs LG QNED80A6A (IPS)

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.

When it comes to image dynamics and brightness, the QNED80A keeps its feet firmly on the ground. It’s not a "light beast" – during our measurements, peak luminance hovered around 350-400 nits. To put it bluntly: these are values that won't fully unleash the potential of HDR formats. So don’t expect the glare of the sun or car headlights in films to blind you. However, this television has a powerful ace up its sleeve that saves the overall image quality – it's the colours. LG engineers have employed an advanced filtration system (technically based on phosphor PFS, marketed as QNED/NanoCell), which does a fantastic job. Thanks to this, despite average brightness, the screen can generate exceptionally saturated and pure colours. Our instruments showed coverage of the wide cinematic DCI-P3 colour gamut at around 93-94%. This is a result that outclasses most standard LCD televisions. In practice, this means that when watching 4K HDR content, the image – although not very bright – is very vivid, lively, and delights the eye with its depth of colours.

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.

Here, regardless of whether you come across the VA or IPS version, the situation looks identical. LG engineers have once again served us their vision of a "gaming look," which unfortunately has little to do with accuracy. When switching to a console, the white balance automatically shifts to very cold regions. The image is dominated by blue, making it seem artificially sharpened, and the white is so aggressive that it almost burns out. This creates an effect we associate with garish retail modes – everything is meant to shine and scream "I’m digital." While some may like this, we must say it bluntly: it is not an accurate image. 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 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.

After professional calibration, the QNED80A in the IPS version has changed beyond recognition, 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 fallen below the threshold of perception (value < 2). The image 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 TV struggles with perfect brightness control (EOTF curve). Due to the limitations of edge lighting and the rather poor adjustment options provided by LG in this area, the TV'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 image after calibration is a class above 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 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.

It often happens that cheap 4K TVs mercilessly expose the flaws of low-resolution materials. Here, it's different. The QNED80A is great equipment for watching content that isn’t perfect. The processor does a great job of scaling the image, making even older recordings look quite decent on the 4K screen – they are consistent and free of digital noise. Interestingly, there’s a gradation reduction feature available in the settings. It’s particularly effective in combating what is known as banding in low-bitrate materials. Of course, you need to approach it with some caution. Due to the lower processing power of the chip (in comparison to the premium series), turning on this option can sometimes result in unwanted artifacts or blurring. Despite this risk, we encourage experimentation, as in many cases this feature can save a viewing of low quality.

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").

When it comes to motion reproduction, the QNED80 unfortunately has a bit of a disadvantage. The TV is built on a 60Hz refresh rate panel, which is quite disappointing for the QNED series in 2025. If you're looking for perfect sharpness in dynamic football matches, you might feel a bit let down. The solution in this situation is the TruMotion system. It allows for artificially adding frames, which smooths out the picture in movies and TV shows. In the menu, you'll 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.

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 is a super-detailed Game Bar that clearly shows all the key parameters. However, the real gem is the Game Motion Plus feature. This motion smoother dedicated to games makes the animation more pleasant to the eye while only slightly increasing input lag. This is a rare and well-functioning combination that deserves big applause for Samsung.

Now comes the moment where we need to vent a little. The lack of Dolby Vision in Samsung TVs has become standard, so there's no use hoping (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 representation of brightness in HDR games, as intended by the creators. Without it, HDR calibration on consoles becomes less accurate, which may result in images that are too dark in the shadows or overly bright in the light 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 lineup due to the release of software version 1131, which restored the crucial HGiG feature 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 to accept. However, LG's engineers have done everything to squeeze the maximum potential out of this 60Hz panel, providing gamers with a desirable set of features. Above all, the TV supports VRR (in the range of 48-60Hz) and ALLM. This means the image is smooth and doesn't stutter, and the TV automatically switches to low latency mode as soon as you grab the controller. Accessing these options is ridiculously easy 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. Even though the screen doesn't support gaming Dolby Vision, HGiG ensures that the TV "understands" how to display games in HDR. This helps avoid the effect of blown-out clouds, which is unfortunately a plague on cheaper LCD TVs.
