Samsung Neo QLED QN90D / QN92D vs LG NANO81A / NANO80A

During synthetic tests, the Samsung QN92D demonstrated remarkable brightness capabilities, reaching an impressive 2000 nits—on par with top models in the market. This level of brightness puts it at the forefront for displaying HDR content, where high brightness is essential. But how does it fare in real movie scenes? Under favourable conditions, such as the light-drenched opening and closing scenes of Life of Pi, the QN92D nearly replicates its lab results, delivering striking brightness levels. However, performance changes in scenes featuring small, bright objects against dark backgrounds, such as the fourth scene in Sicario. Here, brightness levels drop significantly, with maximum values capping at around 600 nits.

As with contrast, these limitations are due to the aggressive local dimming algorithm, which aims to reduce the "halo" effect around bright objects in dark scenes but often sacrifices overall brightness. Consequently, while the TV excels in scenes with abundant light, it faces challenges maintaining brightness with smaller, bright elements on dark backgrounds.

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.

The best mode for colour reproduction on the Samsung QN92D is Filmmaker mode. Although it generally offers good colour quality, it is not without significant issues. Starting with HD/SDR image quality, the main challenge is white balance. The graphs reveal considerable instability, with a dominant red tint that makes the image appear too warm. This imbalance causes shades to shift unnaturally towards warmer tones, potentially affecting the perception of natural colours. Additionally, while contrast, as indicated by the gamma chart, is not the worst, it still falls short of the ideal, impacting overall image quality, especially in darker scenes.

This issue continues with 4K content, such as high-quality series or films. Here too, white balance proves problematic, with noticeable deficiencies in both blue and red, leading to tonal shifts. Tests using the Colour Checker tool confirm these issues, showing a tendency for colours to skew toward yellow hues, further distorting the natural look of the image. While Filmmaker mode remains one of the best options for cinematic content, it could still benefit from improvements, particularly in colour accuracy and white balance.

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.

After calibration, the Filmmaker mode on the Samsung QN92D shows significant improvement, particularly with SDR content. The white balance has been greatly enhanced — previous colour shifts and red dominance have been corrected, resulting in more natural colour reproduction. Although the gamma curve didn’t require major adjustments, its stabilisation has positively impacted overall picture quality.

In high-quality materials, the white balance has also improved. However, contrast remains an area to watch. The EOTF curve initially appears accurate, but closer inspection reveals that the television struggles to maintain consistent contrast in film content, indicating further room for improvement. Despite these areas, one advantage is the TV’s colour saturation. Skin tones are rendered well, and while some colours may be slightly oversaturated, the overall effect is rich and vibrant.

Despite minor contrast limitations, the calibrated Filmmaker mode on the Samsung QN92D delivers excellent picture quality, with natural colours, making it a strong choice for movie watching.

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.

Let's examine how the Samsung QN92D television manages tonal transitions in low-quality materials. The noise reduction function is highly effective, enhancing the fluidity of tonal transitions even under challenging conditions. However, it’s worth noting that, as with other Samsung televisions, this feature can occasionally remove desirable elements, such as film grain, which may affect image authenticity. 

In terms of digital processing, the Samsung QN92D also performs impressively. During testing, the image appeared natural and well-balanced, with details like background branches precisely reproduced, underscoring the television’s ability to enhance the quality of low-resolution materials.

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.

The Samsung QN92D TV features a 144 Hz panel, however, when using the motion smoother, the maximum refresh rate adjusts to 120 Hz. This setup ensures excellent picture quality for both gamers and sports enthusiasts. Additionally, the TV offers a range of image enhancement options, such as the "blur and judder reduction" feature, which lets users fine-tune smoothness on a 10-point scale. Blur reduction sharpens fast-moving objects, while judder reduction smooths out motion, eliminating the "stutter" effect. With these advanced settings, the Samsung QN92D provides optimal visual experiences for dynamic scenes and intense gameplay alike.

The TV performs impressively in terms of motion blur, with minimal issues. The only minor drawback is a slight overshoot effect noticeable on dark backgrounds in our "Ufoludkiem" test. Nonetheless, with its advanced smoothness settings, the Samsung QN92D delivers outstanding performance for both fast-paced scenes and immersive gaming sessions.

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.

The Samsung QN92/QN90 TV is an outstanding choice for avid gamers and is highly recommended. This model provides virtually every gaming feature currently available, enhancing the excitement of gameplay. A standout feature is the 120 Hz panel, delivering impressive motion smoothness, which is especially beneficial during action-packed games. The TV also boasts low input lag, ensuring quick responses to player commands. Additionally, VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode) optimise refresh rates and automatically activate gaming mode, further elevating the gaming experience. An additional bonus is the Xbox app, enabling users to play directly on the TV without needing a console—an exclusive feature in Samsung TVs, adding to their appeal in the gaming world.

Samsung’s Auto Motion Plus Game feature deserves particular praise. This motion smoother is highly effective in gaming, making lower frame rates appear smoother—30 frames per second can look like 45, and 60 Hz can resemble 90 Hz. Crucially, it achieves this without introducing noticeable input lag (keeping it below 25 ms), so gameplay remains highly responsive, unlike many other motion-smoothing options on the market. As a result, players can enjoy a smoother visual experience without sacrificing responsiveness.

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.
