LG QNED93A / QNED90A vs Samsung QN90F / QN92F

Although the number of local dimming zones in the LG QNED93A has not directly translated to noticeably better contrast, it is hard to deny one thing about this model – it is brighter than its predecessor. In synthetic tests, we recorded values around 1400-1500 nits, and more importantly, these results are reflected in real film scenes. In full-screen sequences flooded with white or bright lights, the screen could maintain high luminance, which created a truly decent amazing HDR effect. Unfortunately, where the television could showcase true class, that is in scenes requiring precision, all the magic dissipates. The dimming algorithms, which we mentioned earlier, operate so aggressively that small bright objects – such as distant lights, stars, or the moon – can almost completely disappear. A glance at the test scenes from the film Pan or Sicario 2 (screens 2 and 4) shows how subtle details are dimmed to the limits of their visibility. It's a pity, as a greater number of zones could theoretically have led to significantly better results. Fortunately, there are also strengths. The QNED93A performs well in terms of colour gamut coverage, achieving around 96% of the DCI-P3 standard. As a result, colours in films appear vivid and full, and the picture does not lose intensity even in more demanding scenes. Therefore, one could say that the HDR in this model is solid, although the underdeveloped local dimming algorithms hinder its full potential.

The Samsung QN90F can truly shine with brightness. In our measurements, it achieved over 2200 nits, which directly translates to the viewing experience. In practice, this means that when a film features a very bright scene – for example, a sunrise in The Meg – the screen looks as if it is actually lit by natural light. This is not just a number from a chart, but a real sense of image intensity! However, the television may not always deliver this full power. With smaller details like reflections or lamps, brightness drops to 500–700 nits. This is a deliberate decision by the algorithms – it allows for better control of the contrast between large and small elements, preventing the image from losing balance. Importantly, this is still a huge improvement compared to last year's QN90D, where similar details were often almost invisible, shining at just 200 nits. Here, the HDR effect is much more consistent and credible. The only downside is the colours. The DCI-P3 coverage has stalled at 91%, which in this price bracket can be considered a rather average result.

In filmmaker mode, the colour reproduction on the QNED93A was relatively accurate, although there were some reservations. In SDR content, the white balance was shifted towards warmer tones, which gave the screen a slight yellowish tint overall. The gamma, in turn, led to a slight brightness increase, making the image appear somewhat less natural, especially in scenes requiring precise shading (this is clearly visible in the comparison photo). This is not a problem that immediately stands out to every viewer, but more discerning individuals may feel that the image deviates from the aesthetics intended by the filmmakers. In HDR materials, the situation was somewhat different. The white balance, in this case, was quite good, ensuring that the whites neither leaned towards pink nor unwanted green hues. However, managing brightness turned out to be an issue. An analysis of the EOTF curve revealed that at certain moments, the television could be noticeably too dark where it shouldn't be, losing some detail and lowering the realism of the scenes. This spoiled the reception of HDR effects, which were theoretically supposed to make the biggest impression. For this reason, we decided to carry out calibration.

The colour reproduction of the QN90F was tested in Filmmaker mode and, as is often the case with Samsung televisions, this mode proves to be the best starting point straight out of the box. However, this does not mean that the image is free from flaws. The white balance in both SDR and HDR content was surprisingly good – the colours did not drift in any direction and even in its factory settings, it looked solid. A problem arose with the gamma curves and EOTF, which dictate how the television manages brightness. Here, the QN90F significantly brightened the entire image, causing blacks and colours to lose their intensity, and the overall effect resembled that of an applied milky filter. Fortunately, Samsung, unlike many competitors in the miniLED world, provides the user with plenty of tools to control the settings that we do not find with other manufacturers, such as Chinese producers. Therefore, we decided to see if we could squeeze the full potential out of the QN90F because we know that such a high-end series is capable of much more.

After professional calibration, the Filmmaker mode on the QNED93A has improved primarily in areas that matter most on a daily basis. We managed to correct the white balance and eliminate the yellowish tint in SDR content, which is what we watch most often – television, streaming services, or standard quality films. As a result, the colours look natural and pleasant, making the overall experience much more comfortable. We also made adjustments in HDR mode, but here the biggest issue turned out to be the EOTF curve. Although LG offers some flexibility in the settings, the television still manages brightness on its own terms. It is evident that the local dimming algorithms are not fully refined and can ruin the viewing experience by darkening parts of the image at inappropriate times. Nevertheless, it is worth opting for calibration of this model, especially the mode intended for everyday viewing.

After our adjustment of the settings, the QN90F displayed what it is truly capable of – and it must be admitted that this is one of the best images we have seen on a miniLED screen this year. As we mentioned earlier, the white balance was not a major issue even in its factory state, but only after gamma calibration did it manage to get close to reference values. The same is true for HDR content, where the EOTF curve post-adjustment presents mature and cohesive results. Indeed, in some films, it is noticeable that the smallest elements of the image are slightly brightened, and with a limited number of dimming zones, there is still a risk of halo effect. However, it should be remembered that such phenomena are characteristic of all miniLED televisions, and it is difficult to expect miracles even from the QN90F. The most important thing is that after calibration, the television delivers an image that, in terms of representing the director's vision, confidently competes with many OLED screens available on the market.

The LG QNED93A proves to be a very solid television for everyday use. Its image processor handles scaling extremely well, which means even older films or terrestrial television benefit from increased sharpness and detail. During the screening of "The Godfather," it is clearly visible how upscaling retrieves additional details from the image – the faces of the characters and the texture of their clothing appear much clearer than in the original material.

The digital image processing also deserves praise. The television is equipped with a function for reducing unwanted colour banding and screen irregularities. It works best in the "Medium" setting – subtly smoothing tonal transitions without excessively interfering with the image. As a result, the natural film grain is preserved, and the screen does not appear artificially smooth. It is possible that in some scenes slight colour banding can still be observed, but in practice, the effect is more beneficial than with a stronger intervention from the algorithm.

QN90F handles upscaling very well. Materials in lower resolutions, even SD, are enhanced to a clear and sharp image, in which a lot of detail in the background can be seen. This is a significant advantage, as the television makes older content or everyday television look considerably better than on most budget screens. However, the issue of overscan remains, which is the trimming of the screen edges, and this cannot be turned off in Samsung TVs. This can cause some subtitles on the screen to disappear or Auntie's face from the wedding on the VHS tape to be slightly cut off. 😉

Digital image processing also works well. In the menu, we find a function called "noise reduction," which can smooth tonal transitions and improve the reception of lower quality materials, e.g. from YouTube. At the medium setting, the effect is most beneficial – it does not heavily interfere with details, while eliminating the problem of "stepping" in colours. However, it is worth remembering that the function can be quite aggressive and removes natural grain from older films, so it is best to use it in moderation.

The LG QNED93A is equipped with a 144 Hz panel. This is primarily a nod to gamers, but the fact that higher refresh rates are increasingly making their way into televisions can be viewed positively. In everyday viewing, 120 Hz remains key, and in this respect, the QNED93A performs well. The manufacturer also provides the option to adjust the picture using the TruMotion system – the De-Judder and De-Blur sliders allow you to choose between a cinematic motion character with visible frames and a complete smoothing with theatrical motion.

The QN90F is equipped with a panel that has a maximum refresh rate of 165 Hz, and although this advantage will primarily be appreciated by PC gamers, it is still worth highlighting. In films or sports broadcasts, we are limited to the classic 120 Hz, but this is not a cause for concern. In practice, the additional motion smoother is of greater importance here. With the "Motion Clarity" setting, we can adjust the picture to our own preferences. The blur reduction option is responsible for fluidity and ghosting in sports. Meanwhile, the "judder reduction" function improves motion smoothness in productions shot at 24 frames, such as films and series. If we set it high, the film appears smoother and more fluid than it was actually shot. Lower values, on the other hand, preserve its cinematic "rawness" with a visible film frame.

LG QNED93A is a television that has undoubtedly been prepared with gamers in mind. Right from the outset, we get a complete set – all four HDMI ports operate in standard 2.1, so regardless of whether we connect a console, PC or amplifier, we can be assured of full compatibility. This is important, as many manufacturers still limit themselves to two ports, and here nothing hinders the entire equipment from having maximum capabilities. There is also an automatic game mode (ALLM), which automatically switches the television to the appropriate settings when the console is turned on, as well as variable refresh rate (VRR). This ensures the picture doesn't stutter or jerk, even when the frame rate drops – whether in dynamic shooters or during races.

The 144 Hz panel gives an additional advantage in computer games. While 120 Hz is sufficient for consoles, in the case of PCs, the QNED93A allows for even more – every movement, every glance to the side is refreshed faster, and this makes a difference, especially in e-sports. The manufacturer also considered HDR in gaming – the television supports the HGiG mode, which are guidelines to ensure that the lighting effects are exactly as the game developers intended. To top it off, we get Game Bar – a special information bar that appears on the screen, showing parameters in real-time. You can monitor the frame rate, active VRR functions, or the level of input lag. This solution is useful not only for settings enthusiasts but for anyone who wants to quickly check what mode the television is operating in and whether everything is working as it should.

QN90F has almost everything to be the perfect television for gamers. There’s no need to remind anyone of features like four HDMI ports, VRR, ALLM, or refresh rates reaching even 165 Hz. The Game Motion Plus mode deserves great praise, as it is a unique motion smoother for games. Thanks to this, it adds a few “artificial” frames and makes the image generated from the console look smoother than it should. This is a very unique solution in the world of televisions – rival systems usually do not offer this – and that is why Samsung has had a strong selling point among gamers for years, even despite the lack of support for the still niche Dolby Vision in games.

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

So why do we say "almost" the perfect screen? Unfortunately, like in recent Samsung models, we noticed an issue with the lack of the HGiG feature. This solution allows the television to leave the control of tone mapping up to the console, so that games look exactly as intended by the creators. What's worse, this feature was previously present and disappeared after software updates. Instead of minor improvements, we got a step back. It’s a shame, because without this absence, the QN90F could truly be the ideal choice for gamers in the miniLED category.
