LG UR781 vs LG UA75006LA (VA)

In HDR mode, LG UR781 unfortunately does not impress with its brightness. In tests on five screens, the television achieved only around 200 nits, which is quite a low value for HDR standards. This brightness is similar to levels typical for SDR, causing HDR effects to be insufficiently pronounced, and the image may appear less impressive, especially in dynamic, bright scenes. In HDR mode, it has certain limitations in colour reproduction. This means that colours may not be as intense and rich as in televisions that manage better with a wide colour gamut. In practice, this can make the image less vibrant and dynamic, and HDR effects will not be as spectacular as one might expect. Additionally, UR781 LG has some issues with accurately reproducing colours in HDR mode, resulting in content that may look less vivid.

The LG UA7500 with a VA panel holds brightness at around 350 nits, which does not make a significant impression by today's standards. It is hard to speak of a true HDR experience here – most content looks more like classic SDR with a slight attempt at boosting the highlights. The advantage is that regardless of the tested scene, the effect remained relatively stable. However, we noticed that in very extreme scenes with a lot of fine details, the television can gently dim the image to achieve better black levels, but this comes at the expense of visibility of bright effects. It is also worth noting that the UA7500 is not equipped with any additional technologies for expanding colours. It is neither a QLED panel nor PFS LED, which is why the coverage of the DCI-P3 colour gamut is only 80%, making many HDR films appear flat and not conveying the full diversity of colours.

The colour reproduction in LG UR781 in Filmmaker Mode, which although is the best mode available from the factory settings, is not without its flaws. Firstly, the issue is white balance, where the graph shows dips in blue colour levels. This phenomenon results in a shift of hues towards yellow tones, causing the image to appear warmer than it should. Such deviation means that the colours on the screen are not naturally reproduced, which can be particularly noticeable in scenes with a white or neutral background. This can be confirmed by the Test Color Checker, which showed that some colours "shift" into other shades, meaning that the LG UR781 television does not display colours in accordance with reality. This distortion can affect the visual experience, making movie scenes seem less realistic, and details might be displayed in inappropriate colours, negatively impacting the overall image quality.

In terms of contrast, the analysis of the gamma graph revealed drops to a level of 2.0, whereas the optimal value should be 2.4. This means that the television may display darker parts of the image brighter in certain scenes, which reduces their depth and dynamics. Additionally, on the EOTF curve, which is responsible for brightness reproduction, an unnatural spike was observed at the beginning. This phenomenon can result in excessive brightness boost in the brightest parts of the image, leading to loss of detail in very bright scenes.

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 image is put together quite sensibly and does not irritate at first glance, however, its weaknesses quickly become apparent. This is most evident in scenes with bright points – background lamps or reflections of light on the skin are distinctly exaggerated. The faces of the characters often look unnatural, as if they have been 'overexposed'. Added to this is the default gamma characteristic, which brightens the smallest details and causes the image to lose subtlety in darker areas. Nevertheless, it is a fact that for its price range, the UA7500 in factory mode provides a fairly decent starting point. However, it is clear that without additional adjustment, it will not be possible to avoid these problems, which is why – as with other televisions – we decided to see what could be achieved after calibration.

After calibration, the colour representation in SDR content is quite good. The white balance has been effectively improved, resulting in natural, balanced hues across various scenes. The gamma has also been adjusted, providing more precise detail in the shadows and highlights of the image. As a result, the LG UR781 television performs well in everyday use, offering solid colour quality and clear, well-balanced images in SDR mode.

However, the situation is worse for HDR content. The LG UR781 television does not support a wide colour gamut, which limits the depth and richness of colours that HDR can offer. The EOTF curve deviates from the ideal, resulting in excessive highlighting of details in the bright parts of the image. Unfortunately, this results in significant colour reproduction errors, as confirmed by tests on the Colour Checker. Additionally, the low brightness level of the panel further negatively impacts the quality of HDR images, causing dynamic range effects to be not fully realised, and colours to appear washed out.

Despite some shortcomings in HDR mode, the television has improved significantly after calibration, especially in SDR content. The improvement in white balance and gamma has greatly enhanced image quality, providing a more natural and cohesive colour representation. Compared to its state before calibration, the difference is clear, and the LG UR781 television now offers better performance in everyday use, particularly in the standard dynamic range.

The biggest improvement we noticed was when calibrating the mode intended for everyday SDR content. We managed to smooth out the white balance in an acceptable way and tackle the problem of excessive brightening of fine details due to the gamma curve. As a result, the image gained the consistency and naturalness that was missing in the factory settings. After such adjustments, we can confidently state that for everyday television content, programmes, or materials from YouTube, the LG UA7500 performs very 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 the brightness management; however, the limitations of the construction are immediately apparent. The lack of additional filters to widen the colour palette results in the most vivid colours appearing flat, and the image does not display the intensity we would expect from good HDR. So in SDR, the UA7500 performs quite well, but in HDR – despite corrections – it remains far behind, and this is a characteristic that one must accept when choosing this television.

Now let’s address the function of smoothing tonal transitions and its impact on overall image quality. As illustrated in the photo on the left, this function performs exceptionally mediocrely; we selected the "low" level, which does not improve quality but also does not blur the film grain. There is the option to increase the power of this function, which would soften the gradation; however, one must reckon with the fact that the image will be too softened in some scenes.

On the other hand, regarding image scaling, the television does not perform exceptionally, which can be particularly noticeable with lower resolution content. The LG UR781 television applies a slight, artificial sharpness boost, which makes the image appear sharper, but this primarily results from the overlay of artificial contours. For some users, this can be an advantage, as they prefer more vivid, accentuated details. However, this is a subjective matter—such an effect may not appeal to everyone, especially if they desire a more natural look to the image.

LG UA7500 with a VA panel performed really well in this category. Image scaling from Full HD or even SD materials was surprisingly smooth. The picture looked smooth, edges were not overly jagged, and the television retained a considerable amount of detail, meaning that even older films did not lose their character. It particularly excelled with faces – there were no artificial contours or 'mask' effects, which often occur in cheaper models. The way the television handled tonal transitions in lower quality materials is also noteworthy. Thanks to digital processing, colours did not bleed into each other, and gradients appeared natural and smooth. There was no excessive smoothing of the image or loss of cinematic grain. This makes the UA7500 great for everyday content – from terrestrial television, through sports, to YouTube, where we often watch materials in various resolutions.

The LG UR781 television offers quite decent smoothness for films, thanks to the "True Motion" option, which allows users to adjust the level of motion smoothing on a scale from 0 to 10. The user can choose whether they want to preserve a more traditional, cinematic effect with subtle judder (lower settings) or prefer a smoother, theatrical image that, although slightly deviating from the cinematic standard, may appeal to many.

In dynamic sports content and games, the LG UR781 television performs worse. The television has a 60Hz panel, which limits its interpolation capabilities to these values; therefore, it can improve fluidity in films but cannot reduce motion blur. Additionally, the lack of support for 120 Hz and BFI (Black Frame Insertion) technology means that quick movements of objects become blurred, and the response time of the panel is too long, negatively affecting clarity in fast scenes. As a result, the television may not meet the expectations of gamers and sports fans who are looking for a smooth, clear image without motion blur.

The LG UA7500 is a television with a 60 Hz panel, so it's difficult to expect much admiration in this category. It's more of a screen intended for everyday content or an evening film viewing rather than for following dynamic sporting events or playing action games. It's clear that the manufacturer targeted this model specifically at that group of consumers – and it performs correctly in that regard. We have the TruMotion feature available, which is a motion smoother. It's simple, with only one slider, but it can introduce a noticeable difference. At the lower settings, the image appears more raw and cinematic, whereas at higher values, the motion becomes smoother and more pleasing to the eye.

While gaming on the console, the television LG UR781 offers several important features that can affect the gaming experience, but it also has some limitations. A positive aspect is the presence of ALLM (Auto Low Latency Mode), which automatically optimises picture settings by switching the television LG UR781 into low latency mode, which is beneficial for gamers. The television also supports proper implementation of HGiG, meaning HDR games look as intended by the developers.

Unfortunately, it lacks support for Variable Refresh Rate (VRR), which may result in poorer fluidity of gameplay, particularly in more dynamic games. It also does not support Dolby Vision mode for games, which limits the HDR picture quality in games using this format. The television has a panel with a frequency of 60hz, which means it does not support higher frequencies at other resolutions, such as 1080p@120Hz, 1440p@120Hz, or 4K@120Hz, which is a significant drawback for gamers expecting smoother gameplay at higher resolutions. It also lacks support for G-Sync technology, which limits image synchronisation in games.

However, a positive aspect is the presence of the Game Bar feature, which allows quick access to settings for gamers and makes it easier to adjust picture parameters during gameplay.

The LG UA7500 is a television that can be confidently recommended to "casual" gamers. It lacks a 120 Hz panel and HDMI 2.1 ports, so it cannot fully utilise the potential of modern consoles. However, the manufacturer has included several features that can enhance the gaming experience. Notably, the Game Bar stands out – a very well-designed panel where you can quickly preview and change the most important settings. From this interface, we have access to features like ALLM mode (automatic switching to game mode) and frame synchronization, which is VRR. The VRR range is limited – it works from 48 to 60 Hz – but the mere presence of this feature in such an affordable television makes a positive impression.

Additionally, it supports HGiG, which is the HDR calibration mode for gaming. It sounds good, but based on our testing experiences, we already know that for the UA7500, this option doesn't make much sense. The television doesn't handle HDR very well, so paradoxically, we achieved better results with this mode disabled. This is another indication that the UA7500 is more of a screen for occasional gamers who value simplicity and convenience rather than for those seeking the full experience from the latest consoles.
