LG UA75006LA (IPS) vs Samsung QN90F / QN92F

The version with an IPS panel looks even more modest, where the peak brightness barely reaches 250 nits. In practice, this means that a real sense of HDR effect is out of the question, and the materials viewed resemble rather ordinary SDR. Similar to VA panels, the image behaves stably on most test patterns, but in demanding scenes with fine details, the television has a tendency to slightly dim the image. This allows for slightly better blacks; however, this comes at the expense of losing detail in bright elements. The absence of additional colour filters is also noticeable here. The UA7500 with an IPS panel does not belong to QLEDs or PFS LED panels, and the DCI-P3 colour gamut is limited to 80%, meaning that HDR films lack significant colour depth and appear quite flattened.

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.

The Filmmaker mode on the LG UA7500 performs better than one might expect from such a budget television, but let's not get carried away with praise. The picture is quite well put together and does not irritate at first glance, but its weaknesses soon start to show. This is most evident in scenes with bright points – lamps in the background or reflections of light on the skin are distinctly overemphasised. Characters' faces often appear unnatural, as if they have been 'overexposed'. Additionally, the default gamma setting brightens even the smallest details, causing the image to lose subtlety in darker areas. However, it remains true that for its price bracket, the UA7500 in factory mode offers a fairly decent starting point. It is clear that without additional adjustment, it will not be possible to avoid these issues, which is why – as with other televisions – we decided to see what could be achieved after 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.

The greatest improvement we noticed was during the calibration of the mode intended for everyday SDR content. We managed to smooth out the white balance in an acceptable way and control the issue of excessive brightening of fine details due to the gamma characteristics. As a result, the image gained the consistency and naturalness that was lacking in the factory settings. After this correction, we can confidently state that for everyday television content, programmes, or materials from YouTube, the LG UA7500 performs really well – especially after professional calibration. The situation is somewhat different for HDR content. Here, calibration allowed us to tame the white balance and slightly improve brightness management, but the limitations of the design are immediately evident. The lack of additional filters expanding the colour palette means that the most vibrant colours appear flat, and the image does not have the intensity one would expect from good HDR. Therefore, in SDR, the UA7500 performs quite well, but in HDR – despite the corrections – it remains far behind, and this is a feature one must accept when choosing this television.

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 version with the IPS panel performed noticeably worse here. Image scaling was uneven – this was particularly evident in lower quality materials, where edges became jagged and the image appeared less detailed. At times, there was also a slight blur that diminished sharpness and made the overall impression seem less refined than in the VA version. The solution proved to be the tonal transition smoothing function. On the medium setting, it worked very well – it did not spoil the image with excessive softening, while simultaneously smoothing colours in such a way that everyday content gained coherence. The difference was particularly noticeable with television programmes or streaming materials with poorer compression quality, where the television with the function on presented itself much better. This is one of those additions that are worth keeping active, as they significantly enhance the experience of daily content.

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.

LG UA7500 is a television with a 60 Hz panel, so it is difficult to expect much excitement in this category. It is rather a screen designed for everyday content or an evening film screening rather than for following dynamic sports events or playing action games. It is clear that the manufacturer aimed this model at this group of consumers – and in this regard, it performs adequately. We have the TruMotion function available, which is a motion smoother. It is simple, has only one slider, but can make a noticeable difference. At the lower range, the picture looks more raw and cinematic, while at higher values, the motion becomes smoother and more pleasant to the eye.

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 UA7500 is a television that can be confidently recommended to "casual" gamers. While it lacks a 120 Hz panel and HDMI 2.1 ports, so fully utilising the potential of modern consoles is out of the question. However, the manufacturer has included a few features that can enhance the gaming experience. Noteworthy is the Game Bar – a very well-designed panel where you can quickly preview and change the most important settings. From this panel, we have access to various features, including the ALLM mode (automatic switching to game mode) and frame synchronisation, namely VRR. The range of VRR is limited – it operates from 48 to 60 Hz – but the mere presence of this feature in such an affordable television leaves a positive impression.

Additionally, there is support for HGiG, which is the HDR calibration mode for gaming. This sounds good, but from our testing experience, we know that in the case of the UA7500, this option is not particularly useful. The television does not perform very well with HDR, so paradoxically better results were achieved with this mode turned off. This is another signal that the UA7500 is more of a screen for occasional gamers who value simplicity and convenience rather than for those seeking a full immersion experience with the latest consoles.

QN90F has almost everything to become the perfect television for gamers. Features such as four HDMI ports, VRR, ALLM, and refresh rates reaching up to 165 Hz hardly need reminding. It deserves high praise for the Game Motion Plus mode, which is an original motion smoother for games. Thanks to it, you can add a few “artificial” frames and make the image generated by the console look smoother than it should. This is a very unique solution in the world of televisions – competing systems usually do not offer this – and that is why Samsung has had a strong bargaining chip among gamers for years, even despite the lack of support for the still niche Dolby Vision in games.

So why do we refer to it as an “almost” perfect screen? Unfortunately, similar to recent Samsung models, we noticed a problem with the absence of the HGiG feature. This is a solution that allows the television to leave the control over tone mapping to the console, so that games look exactly as the creators intended. What’s worse, this feature was previously present and disappeared after software updates. Instead of minor improvements, we received a step backwards. It’s a shame, because without this deficiency, the QN90F could truly be the ideal choice for gamers in the miniLED category.
