Samsung OLED S85F / S84F (QD-OLED) vs LG NANO81A / NANO80A

As an OLED, the Samsung S85F can really shine – literally. Under favorable conditions, it can generate brightness exceeding 750 nits. This is hugely significant because most movies are created with displays around 1000 nits in mind. In practice, this means that in scenes with moderately large bright elements, the image can look simply fantastic. However, it's not always so rosy. When there is a massive amount of light on the screen – whether it's a vast bright background or an entire screen filled with white – the S85F must tone it down. The brightness can drop by even four times in such scenes. This limitation is known to basically every OLED in this price range, so we don't consider it a particular failing. However, something that deserves praise is what sets this model apart from the competition – color gamut coverage. Thanks to the QD-OLED panel, our colorimeter showed values exceeding 100% DCI-P3 coverage and as high as 86% for the ultra-wide BT.2020 palette. Such results are hard to find even in televisions that cost several times more.

If you're counting on HDR in the NANO81A to bring tears to your eyes, I have to disappoint you. This TV is simply too dark to show what this format is really about. With a brightness of just 250 nits, HDR here essentially exists only on paper. In practice, during a viewing session, it's very hard to distinguish whether we're watching high dynamic range content or regular SDR – it simply lacks that "punch" of light in bright areas of the image. But, to not have all criticism, we do have a glimmer of light at the end of the tunnel – and it’s quite clear. It's about color gamut coverage. Here, the NanoCell filter shows that it's not just marketing nonsense. Our measurements indicated that the coverage of the DCI-P3 space is around 88%. This is really a solid result that positions this model significantly above typical budget models based on regular white LED lights without any filters. Of course, it's still a bit lacking compared to the level of quantum dot TVs (QLED) or advanced panels with PFS filtering, but for this price range, the colors are surprisingly saturated and vibrant. It's just a shame that this low brightness doesn’t allow them to fully "spread their wings" with the Nano filter.

Samsung, as befits a manufacturer with ambitions, equipped the S85F with a mode called Filmmaker. Its task is simple: to make the colors on the newly purchased television as true to what the director wanted us to see as possible. Sounds great… but, as often happens, a great-sounding theory doesn’t always translate into perfect practice.

In the tested unit, it quickly became apparent that the image – due to an excess of blue and red – looked as if someone had overdone the saturation a bit. As a result, quite significant color errors appeared, particularly in 4K content. To make matters worse, there was a brightness issue – the S85F could brighten most scenes more than it should, taking away their intended mood.

Fortunately, Samsung televisions, including the S85F, offer an impressive number of settings for advanced calibrators. This means we could check what this panel is truly capable of when it gets into the right hands.

For every movie fan, the natural choice in LG televisions is the Filmmaker Mode. This mode is designed to display the image as the director intended – without unnecessary "enhancements." Unfortunately, in the case of our test unit NANO81A, the factory settings left something to be desired. The main issue turned out to be white balance. Measurements showed a clear deficiency of blue color, which practically translated to many scenes having a slightly yellowish, almost "too yellow" tint. The white was not perfectly clean, which detracted from the freshness of the image. Additionally, brightness management was not ideal either – the factory-set gamma was too low. The image often appeared oversaturated, as if it had been pulled too much from the shadows, losing its naturalness and depth. Fortunately, LG, even in this relatively low price segment, does not block access to advanced settings. The calibration capabilities of this model are immense, which is a big plus for those who like to "dig around" in the menu. We decided to approach the topic in our own way and see how much we could extract from this panel with professional calibration.

Thanks to the vast number of settings in the menu, we managed to bring the S85F almost to perfection. White balance in SDR content? Literally perfect – deviations do not exceed a value of "1". Thus, it can be confidently said that in materials with not very high dynamics, we have an image close to reference.

In HDR content, minor issues did arise, but they are of little significance in practice – most errors fall below the threshold of perception, which is a value of "3". We also managed to tame the S85F regarding brightness management – the EOTF curve, even in films, adheres to an almost perfect line. This is one of those cases where after calibration, you can comfortably forget about the settings and simply enjoy movies and series at the highest level.

After calibrating the NANO81A, it's a completely different television. What LG offers in terms of image enhancement tools even in such an inexpensive model deserves a big plus. We were able to completely eliminate that annoying yellowing of whites and make the colors natural, juicy, and simply "true." In SDR content (such as regular TV, YouTube, or older films), the picture now looks infinitely better – it's clear, well-balanced, and no longer strains the eyes with strange hues. It's evident that this panel has considerable potential, which is simply wasted by poor presets out of the box. However, we have one serious reservation that calibration cannot fully overcome – it's about brightness management in HDR mode. The algorithm LG uses in this model is designed very conservatively. The television deliberately dims the image in HDR to avoid overexposing an already weak black from the IPS panel. The developers faced a choice: either provide more light and accept that black will turn light gray, or reduce the brightness to maintain any contrast. They chose the latter. Nevertheless, after our adjustments, watching anything on the NANO81 is significantly better.

The tone transition smoothing feature in the S85F works really well – it can completely eliminate the problem of visible bands in very poor quality materials, even from YouTube. Unfortunately, even the lowest level of this option comes with compromises. Noise reduction is aggressive enough that it can smooth out film grain, which many of us consider an element of the cinematic atmosphere. At the "Standard" level, we did not notice that this feature removed anything significant from the image, so we can recommend this setting. On the other hand, the "High" level is a different story – it can smooth not only noise but also fine, desirable details such as the texture of objects.

When it comes to image scaling, the S85F performs very well. The material looks sharp, and the only minor imperfection is slightly visible contour jaggedness. And there’s the ongoing issue with Samsung televisions – overscan. This can cause some scenes to have their frames slightly trimmed, which is worth keeping in mind when watching very old content.

It often happens that cheap 4K panels mercilessly bring all the "dirt" and imperfections of lower resolution materials to light. However, in the case of the LG NANO81A, the situation is quite different. It’s a really solid performer when it comes to handling content that is far from ideal. The built-in processor does a great job with upscaling. Even older recordings look quite decent on this screen – the image is coherent, cleaned of digital noise, and simply pleasant to the eye. A big plus is the gradation reduction feature that you will find in the settings. It is exceptionally effective in combating color banding, which is a lifesaver when watching low bitrate materials, for example from some streaming services or older files from the internet. However, it is worth maintaining a certain vigilance. Since we are dealing with a less efficient chip than in LG's top models here, too aggressive an adjustment of this option can sometimes result in minor artifacts or a slight blurring of details. Despite this risk, I definitely encourage experimentation with this feature – in many cases, it can save the viewing experience and make low-quality material fully watchable.

S85F is a hellishly fast television – and this is not just an empty catchphrase for effect. Thanks to the 120 Hz OLED panel, dynamic scenes, whether in games or while watching a live match, look exactly as they should – smoothly, sharply, and without the feeling that something is "escaping" from the frame. The lightning-fast pixel response time, typical of OLEDs, plays a crucial role here. Transitions between frames are practically instantaneous, and the image remains clear even during the fastest camera movements. A ball flying across half the field? A car racing in a chase scene? Everything here is clear and free of the characteristic "trail" found in LCDs.

This is exactly what we expect from a good OLED – zero compromises in motion fluidity. The S85F gives the feeling that regardless of the pace of the action, we can focus on what is happening on the screen, rather than on the imperfections of the image.

In terms of motion fluidity, the NANO81A unfortunately has a few drawbacks. The TV is based on a panel with a refresh rate of 60 Hz. If you're looking for perfect sharpness in dynamic football matches or fast-paced action games, you might feel somewhat unsatisfied. With such a low native refresh rate, fast-moving objects on the screen will always be a bit blurry.

[UPDATE] We have updated our 2025 Samsung TV reviews following the release of firmware version 1131, which officially restores the essential HGiG (HDR Gaming Interest Group) support.

The S85F has practically everything it needs to become the dream screen for gaming. Four fully-fledged HDMI 2.1 ports with a bandwidth of 48 Gb/s, support for VRR, ALLM, a super-detailed Game Bar that clearly shows all parameters – and on top of that, a gem in the form of Game Motion Plus. This is a motion interpolator that makes animation in games more enjoyable, with only a slight increase in input lag. This is a rare combination, and Samsung deserves a big plus for it. Now comes the moment where we have to complain a bit. The lack of Dolby Vision in Samsung TVs is already standard, so there's no point in hoping (unless something changes in a few years) – but the disappearance of HGiG after the software update is something that’s hard to explain. HGiG (which stands for HDR Gaming Interest Group) is a mode that allows for precise reproduction of brightness in HDR games, according to the creators' intention. Without it, HDR calibration on the console becomes less precise, so we might end up with an image that's too dark in the shadows or overly bright. Perhaps Samsung will fix this in the next update – and we have high hopes for that. Because if HGiG returns, the S85F will become almost the perfect TV for gamers.

NANO81A is unfortunately not a device designed for e-sports. The lack of support for a 120 Hz signal is a fact that users planning to purchase this model must simply come to terms with. Nevertheless, LG engineers have worked hard to squeeze the maximum capabilities out of this 60 Hz panel, offering a set of features that genuinely enhance the gaming experience. Above all, the television supports VRR technology (in the range of 48–60 Hz) and ALLM. As a result, the image remains stable and does not "tear," and the device automatically switches to low-latency mode as soon as it detects a signal from the console. Managing these settings is incredibly simple thanks to a dedicated system overlay that allows for a quick overview of parameters without leaving the game. A significant advantage is the support for the HGiG format. This solution is crucial for owners of modern consoles, as it enables the TV to correctly "understand" the intentions of game developers regarding HDR tone mapping. In practice, this helps avoid the effect of "blown out" bright spots, such as clouds or light sources, which unfortunately is a common issue in budget LCD televisions.
