Samsung QN85F vs LG QNED93A / QNED90A

Although more than twice the number of dimming zones compared to its predecessor did not translate into a spectacular jump in black levels and contrast, we definitely felt it in the HDR effect itself. The QN85F is up to 50% brighter than last year's model, making a huge impression in dynamic scenes. The peak brightness can reach almost 1700–1800 nits, which is truly impressive for Mini-LED in this class. The best part is that almost regardless of the scene being watched, the HDR effect remains strong and vibrant. In four out of five test scenes, brightness was maintained around 1000 nits, a level that in most cases allows the viewer to experience the true magic of this format. Of course, in scene number 4 from the film Sicario 2, the limitations of Mini-LED technology become apparent – the brightness of the helicopter’s small light drops to around 500 nits. This result is not stellar, but it is still much more acceptable than last year's model. Samsung therefore deserves applause, as the improvement in brightness in the QN85F is drastic compared to its predecessor. However, it is a shame about a certain trend visible in this year's televisions – the manufacturer has worsened the colour gamut coverage. Although the QN85F has a QLED panel, its score of around 90% DCI-P3 is average, and in the most demanding films, it can lead to less vibrant colours than its predecessor. Despite this shortcoming, the overall HDR effect stands at an excellent level and truly makes a big impression in this class of devices.

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.

Samsung QN85F offers several preset picture modes, but by default, when the television is turned on, it starts in "Eco" mode. And we could actually end the discussion here, because for such a model, using this setting makes no sense – the picture is washed out, unpleasant, and far from what we expect from a television of this class. We therefore carried out our tests in the best of the available modes, which is the Filmmaker mode. Its purpose is to faithfully reproduce what the directors saw during the filming of the movies, and indeed this is the setting that performs best among all factory options. However, this does not mean that it is without flaws.

Both in SDR and HDR, the QN85F quite strongly emphasised warm colours. This resulted from deficiencies in white balance, where there was a distinct lack of blue. Additionally, the picture was sometimes overexposed – as indicated by both the gamma brightness characteristic and the EOTF curve, which showed that the television tends to blow out scenes. In SDR, the colour reproduction errors (Delta E levels of 4-5) were still acceptable, but in HDR the discrepancies became quite large and clearly deviated from what the creators intended to show us. Fortunately, Samsung provides a wide range of calibration tools in its televisions, so – as always – we proceeded with professional calibration to see how much could be improved.

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.

After calibrating the film mode, we managed to tame the colours in both modes to near perfection – most of them did not exceed an error value of 3, which is the threshold of perception by the human eye. The image became more natural, fuller, and at the same time free from bloom, which was noticeable right after taking the television out of the box. This shows the great potential of the QN85F and how well it responds to precise settings. However, this does not change the fact that certain technological barriers cannot be overcome. Despite the enormous benefits of calibration, there are still limitations of the panel itself. Although the number of dimming zones has doubled compared to its predecessor, the algorithms controlling the backlighting can manipulate brightness in their own way. Sometimes this leads to slight colour inaccuracies or gently visible halo effects around bright objects. Nevertheless, the experience after calibration is truly pleasant and demonstrates how good a screen the QN85F can be if we just take a moment for proper settings.

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.

Although the native tonal transitions on the QN85F with 4K material perform excellently, we do not always deal with content in the highest resolution. At that point, it becomes crucial how the television handles upscaling and digital image processing. This process is managed by Samsung's proprietary processor – AI NQ4 Gen2. In practice, it operates very efficiently. If visible colour banding or other undesirable phenomena occur on the screen, for instance, in materials from YouTube, they can easily be smoothed out using the "noise reduction" feature. Set to a medium level, it improves tonal transitions without excessively blurring desired details. However, it is important to remember that – as with most Samsung televisions – this function heavily interferes with the film grain. Therefore, during cinematic screenings, it is wise to use it cautiously to avoid losing the natural character of the image.

The upscaling itself looks very good. Test materials in lower resolutions were displayed sharply and clearly, with a great deal of detail. The only downside remains the issue of overscan, which is the trimming of the edges of the screen. In most situations, this is not noticeable, but with very old materials below HD quality, there may be cases where a fragment of the image from the left side gets slightly cut off.

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.

Motion smoothing and fluidity in the QN85F is a topic worth discussing in more detail, as the television is equipped not with a standard 120 Hz panel, but with a 144 Hz one. The extra hertz will mainly be appreciated by PC gamers, but the mere presence of such an option can be seen as a nice addition and a sign of the times – it’s hard to complain about the trend towards faster panels, as in practice, each of us would prefer the image to be as smooth as possible. However, the most important thing is how the television handles typical 120 Hz refresh rates – in the case of consoles, sports, or films recorded at 24 or 30 frames per second. Here, the QN85F performs really well. In films, one can easily adjust the character of the image thanks to the "image clarity" function, where we find two adjustable sliders. Key for screenings is the one responsible for reducing judder. Lower values give the image a more cinematic character with preserved "frame rate," while higher values lead to strong smoothing reminiscent of television theatre.

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 Samsung QN85F makes a really great impression in terms of gaming features. It has four HDMI 2.1 ports, so we can easily connect multiple devices simultaneously. There is also variable refresh rate (VRR) which prevents screen tearing, as well as an automatic game mode (ALLM) that allows the television to switch to the appropriate settings when we start the console. Additionally, it supports refresh rates of up to 144 Hz – something that PC gamers will particularly appreciate, but the mere fact that such an option is available shows that Samsung is fully committed to supporting gamers. The Game Bar panel also deserves praise. It provides a quick overview of the most important parameters – from frame rate to refresh mode, even including shortcuts to picture settings. Instead of navigating through the entire menu, everything is at hand, which proves to be very convenient in practice. However, the most interesting addition is the Motion Plus gaming feature. It's effectively a motion smoother adapted for the gaming world. When enabled, the image becomes smoother, sometimes looking as if we've gained several extra frames, and importantly – the response time doesn’t increase enough to hinder gameplay. This solution truly sets Samsung's 120Hz televisions apart from competitors.

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

The only major downside remains the lack of proper HGiG support. This is a standard responsible for correct tone mapping in HDR games, meaning that brightness and contrast are displayed as intended by the creators. Without HGiG, we have to adjust brightness manually, which doesn’t always yield perfect results. The feature was available in previous models, but it vanished from the QN85F after one of the updates. We hope that Samsung will quickly resolve this issue, and we will keep checking to see if it has been fixed.

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.
