LG UT8100 (IPS) vs LG UA75006LA (IPS)

The LG UT8100 television unfortunately does not meet expectations in the HDR effect category. A peak brightness of only 300 nits on the luminance chart is well below the required value to fully enjoy HDR effects. In practice, the image resembles SDR quality more than true HDR, which is particularly evident in demanding high-contrast scenes. The coverage of the DCI-P3 colour palette is only 82%, which further limits the ability to present vibrant and rich colours. Instead of impressive visual experiences, we receive a muted and washed-out image. For those looking for a television to fully utilise HDR content, the LG UT8100 model turns out to be quite disappointing.

It looks even more modest in the version with an IPS panel, where the peak brightness only reaches 250 nits. In practice, this means that a real sense of HDR effect is out of the question, and the materials being viewed resemble regular SDR. Similar to VA panels, the image behaves stably across most test patterns, but in demanding scenes with fine details, the television tends to slightly dim the picture. As a result, blacks appear a bit better, but at the cost of losing detail in bright elements. The absence of additional colour filters is also noticeable here. The UA7500 in the IPS version is neither a QLED nor a PFS LED panel, and the DCI-P3 colour gamut stops at 80%, which means that HDR films lack significant colour depth and appear quite flat.

The Filmmaker Mode on LG UT8100, while theoretically the best for watching movies, has significant issues. The biggest problem is the white balance – drops in blue cause a noticeable yellowing of the image, visible in both HD and 4K content. These issues are confirmed by measurement results in the Colour Checker test, which indicate significant deviations in colour reproduction.

In terms of brightness characteristics, both HD and 4K content exhibit a large tonal boost. The gamma curve in both cases remains well below the reference value of 2.4, which leads to excessive brightening of darker elements of the image. A similar problem is evident in the EOTF curve – in the case of 4K content, the TV struggles to manage brightness correctly, resulting in issues with screen brightness. This means the factory settings of this model require significant adjustment to achieve better picture quality.

The Filmmaker mode on the LG UA7500 performs better than you might expect from such a budget television, but let’s not get carried away with admiration. The picture is put together quite sensibly and at first glance is not irritating; however, its weaknesses quickly become apparent. This is most noticeable in scenes with bright points – lamps in the background or reflections of light on skin are clearly oversaturated. The faces of characters often appear unnatural, as if they have been "blown out." Additionally, the default gamma setting brightens even the slightest details and causes the picture to lose subtlety in the darker areas. That said, for its price range, the UA7500 in factory mode provides a pretty decent starting point. However, it is clear that without additional adjustment, these issues won't be avoided, which is why – as with other televisions – we decided to see what could be achieved after calibration.

After calibrating the Filmmaker Mode, the gamma has been aligned to practically perfect, reference values, which has significantly improved the overall tonal characteristics in HD content. 4K HDR content also looks better, although some issues are still visible at the extreme ends of the graph, where the curve deviates from the ideal. The EOTF curve performs worse since the TV struggles to maintain the correct brightness values. As a result, the image in some scenes may be too bright or slightly dim, which stems from the device’s design. Nevertheless, the calibration brought significant improvement, particularly for HD content, where the tonal balance and colour reproduction are now at a much higher level.

The biggest improvement we noticed was when calibrating the mode intended for everyday SDR content. We managed to smoothly adjust the white balance in an acceptable manner and tame the issue of excessive brightening of small elements due to the gamma characteristics. As a result, the image gained consistency and a naturalness that was lacking in the factory settings. After such a correction, we can confidently say 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 did manage to tame the white balance and slightly improve brightness management, however, the design limitations are immediately apparent. The lack of additional filters that expand the colour palette means that the most vibrant colours appear flat, and the image lacks the intensity one would expect from good HDR. In SDR, the UA7500 performs quite well, but in HDR – despite the corrections – it remains far behind, and this is a characteristic that one must accept when choosing this television.

The fluidity of tonal transitions is also correct, although the effect depends on the settings. The update improved the operation of the smooth gradation function, smoothing transitions better than before, but introduced minor issues with detail loss, e.g. on textures.

Image scaling on LG UT8100 performs very well. The image presents itself decently, with no major issues regarding edge aliasing. Details are preserved at a satisfactory level, making materials of lower resolution look really solid on this television. As a result, users can enjoy watching older content without any noticeable defects in quality.

The version with the IPS panel performed noticeably worse here. Image scaling was uneven – this was especially evident in lower quality materials, where edges became jagged and the image looked less detailed. At times, there was also a sense of slight blurriness, which took away sharpness and made the overall picture seem less refined than in the VA version. The tonal smoothing function turned out to be a rescue. On medium settings, it worked quite well – it did not ruin the image with excessive softening, while also smoothing out colours in such a way that everyday content gained consistency. The difference was particularly noticeable with TV programs or streaming materials of poorer compression quality, where the television with the function enabled presented itself much better. This is one of those additions that are worth keeping active, as they significantly improve the reception of everyday materials.

LG UT8100, equipped with a 60 Hz panel, is particularly suited for those watching movies. The television offers the TruMotion system with a de-judder effect adjustment, which allows users to tailor the smoothness of the picture – from more choppy to exceptionally smooth, resembling a soap opera effect, depending on user preferences.

LG UA7500 is a television with a 60 Hz panel, so it's hard to expect any excitement in this category. It's more of a screen intended for daily content or an evening movie session rather than for following fast-paced sports events or playing action games. It’s clear that the manufacturer designed this model specifically for that audience – and it performs well in that regard. We have the TruMotion function available, which is a motion smoother. It’s simple, has only one slider, but can make a noticeable difference. At the lower range, the image looks more raw and cinematic, while at higher values, the motion becomes smoother and more pleasurable to the eye.

LG UT8100 offers basic features for gamers, such as ALLM and Game Bar, which makes it easier to access settings. The TV also supports HGiG, improving picture quality in HDR games. Unfortunately, the lack of support for Dolby Vision and VRR limits the device's capabilities, as does the 60 Hz panel, which excludes support for 120 Hz resolution. This model is more suited for less demanding gaming applications.

LG UA7500 is a TV that can be confidently recommended to "casual" gamers. While it doesn’t feature a 120 Hz panel or HDMI 2.1 ports, making full use of the potential of modern consoles isn’t something we can expect. However, the manufacturer has included several additions that can enhance the gaming experience. Notably, there's the Game Bar – a very nicely designed panel that allows quick access to and changes of the most important settings. From this panel, we have access to the ALLM mode (automatic switching to game mode), as well as frame synchronization, or VRR. The range of VRR is limited – it works from 48 to 60 Hz – but the mere presence of this feature in such an affordable TV leaves a positive impression.

Additionally, it also supports HGiG, which is a HDR calibration mode for games. It sounds good, but from our testing experience, we know that for the UA7500 this option doesn’t make much sense. The TV doesn't perform well with HDR, so paradoxically, we achieved better results 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 looking for the full experience from the latest consoles.
