Samsung S85F (WOLED) vs LG QNED80A6A (IPS)

For most of the time, let's say in 90% of film scenes, viewers won't see practically any difference between the S85F versions. When small but very strong light points appear on the screen – a lantern in a dark alley, a gunshot, the sun breaking through the clouds – this WOLED panel (like the smaller S85F) performs wonderfully. Our measurements showed peak brightness at around 750 nits. We can confidently state: this is an excellent 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 power brightly. Examples include a slide with a white background, a ski jump scene, or our test sequences (5) from the movie The Meg. And here, unfortunately, the results diverge quite significantly to the detriment of the WOLED panel variant. Our measurement equipment was able to measure a maximum of about 250 to 300 nits of brightness in such conditions. Just to be clear: the same model on a QD-OLED panel in the same test is almost twice as bright. The second issue: colors. And here we also have to be honest – QD-OLED has a design advantage. Why? It’s simple. QD-OLED creates colors from three components (red, green, and blue) and does not need an additional white subpixel. The WOLED panel we are testing uses this white subpixel mainly to boost overall brightness. The effect is that QD-OLED is able to show a slightly wider color palette, and the colors are a bit "cleaner." But let’s be clear: it’s not that the colors on this WOLED panel are bad! On the contrary, they are actually very good. Coverage of the DCI-P3 film palette at 97% and 71% for the wider BT.2020 palette is still a high standard. We just have to honestly admit that this few percent advantage in color coverage is on the side of QD-OLED technology and may be noticeable in very specific moments.

When it comes to image dynamics and brightness, the QNED80A has its feet firmly on the ground. It is not a "light beast" – during our measurements, peak brightness oscillated around 350-400 nits. To put it plainly: these are values that will not allow HDR formats to fully spread their wings. So don’t expect the glare of the sun or car headlights in movies to blind you. However, this TV has a powerful ace up its sleeve that saves the overall view of the image – it is the colors. LG engineers have implemented an advanced filtration system here (technically likely based on a PFS phosphor, marketed as QNED/NanoCell), which does a fantastic job. Thanks to it, despite the average brightness, the screen can generate exceptionally saturated and pure colors. Our instruments showed coverage of the wide DCI-P3 cinema palette at the level of 93-94%. This result outclasses most standard LCD TVs. In practice, this means that when watching 4K HDR content, the image – while not particularly bright – is very plastic, vibrant, and pleases the eye with the depth of colors.

When it comes to factory color reproduction, our test sample in SDR mode suffered from a slight deficiency in red and yellow color. This resulted in a subtle yellowish tint visible in the shades of white. However, this is not the biggest problem with the S85F. Similar to the QD-OLED panel variant, the biggest issue with this model is the way it presents HDR content. When we look at the EOTF curve graph, it is easy to see that the television has quite significant problems with overly brightening the image. This causes the final picture in many scenes to become very unnatural.

Here, regardless of whether you encounter the VA or IPS version, the situation looks identical. LG engineers once again served us their vision of a "gaming look," which unfortunately has little to do with accuracy. After switching to console, the white balance automatically drifts into very cold areas. The image is dominated by the color blue, making it seem artificially sharpened, and the white is so aggressive that it is almost burned out. This creates an effect that we associate with bright retail modes – everything is supposed to shine and scream "I am digital." While some may like this, we must say it straight: this is not an accurate image. If you care about naturalness, we suggest checking the settings right away and changing the color temperature to a warmer one.

After calibrating in Filmmaker mode, we managed to eliminate most of the unwanted effects. In SDR content, the television performs exemplary, and its color reproduction errors do not exceed a value of 2, which is an excellent result. A bit worse, although still very good, are the HDR quality contents. While we were able to eliminate a significant unnaturalness in the image caused by too high a positioning of the 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 slight issues showing all the details in the image. We must point out right away that it is highly unlikely that an average viewer would notice any shortcomings in the image. The final effect after calibration is rated as exemplary.

After professional calibration, the QNED80A in the IPS version has changed beyond recognition, especially in "regular" content (SDR). We managed to eliminate the greenish tint and calm down the overly bright gamma. In classic television or older games, color errors (DeltaE) fell below the threshold of perceptibility (value < 2). The image is now consistent, natural, and truly pleasing to the eye. The situation is somewhat more complicated in HDR mode. Although the colors are already in place, the television has trouble perfectly controlling the brightness (EOTF curve). Due to the limitations of edge lighting and the rather poor adjustment options provided by LG in this area, the television's software sometimes "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 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 posterization (the "stepping" effect of colors), even with heavily compressed materials, such as from streaming services. However, using this feature requires making 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 the golden mean, not causing visible loss of important details, so we can recommend it. However, we advise against using the "High" level, which removes not only noise but also desired details, such as texture or structure of objects on the screen.

The scaling (upscaling) process of lower resolution content works very well in the S85F. The image is sharp and clear. The only minor imperfection we observed is occasional, slight aliasing on the edges. The television also still exhibits characteristics typical of this manufacturer, such as active "overscan" (slight magnification of the image). This should be kept in mind, especially when watching older materials, as it may result in a minimal cropping 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 upscaling the image, making even older recordings look quite decent on a 4K screen – they are consistent and free of digital noise. An interesting feature is the gradation reduction available in the settings. It is quite effective in combating so-called banding (color banding) in low-bitrate materials. Of course, one should approach it with some caution. Due to the lower computing power of the chip (compared to the premium series), enabling 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.

The 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 instantaneous 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 devoid of the characteristic motion blur typical of LCD panels (the so-called "tail").

In terms of motion reproduction, the QNED80A unfortunately has a tough time. The television is based on a 60Hz refresh rate panel, which in 2025 in the QNED series is quite a disappointment. If you are looking for perfect sharpness in dynamic soccer matches, you might feel a bit unsatisfied. A solution in this situation is the TruMotion system. It allows for artificially adding frames, which smooths out the image in movies and series. In the menu, you will find the 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.

In the gaming section, we won't sugarcoat it for you – the QNED80A is not e-sports equipment. The lack of support for 120Hz signal is a fact that must be accepted. However, LG engineers have done everything to squeeze the maximum potential out of this 60 Hz panel, providing gamers with a set of desired features. First and foremost, the television supports VRR (in the range of 48-60Hz) and ALLM. This means that the image is smooth, does not stutter, 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 is 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. This helps us avoid the issue of blown-out clouds, which is unfortunately a plague on cheaper LCD televisions.
