Sony X75WL vs LG UA75006LA (VA)

The luminance chart for the Sony X75WL revealed a peak brightness of just 350 nits, which is underwhelming for an HDR-capable display. This limited brightness means that HDR scenes lack the depth and impactful highlights expected for immersive viewing. Additionally, the subpar coverage of the DCI-P3 colour gamut results in a less vibrant colour representation, negatively impacting the overall quality of HDR content. The combination of insufficient brightness and poor colour gamut coverage significantly diminishes the intended HDR effect, making this model a less compelling choice for those prioritising HDR performance.

The LG UA7500 with a VA panel has a brightness that hovers around 350 nits, which, by today’s standards, isn't very impressive. It's hard to talk about a true HDR experience here – most content looks more like classic SDR with a slight attempt at highlights enhancement. One advantage is that regardless of the test pattern, the effect remained relatively stable. However, we noticed that in very extreme scenes with a lot of fine detail, the television can slightly dim the image to achieve better black levels, but this comes at the cost of visibility of bright effects. Additionally, it should be noted that the UA7500 is not equipped with any extra technologies for expanding color. It is neither a QLED panel nor a PFS LED, which is why the coverage of the DCI-P3 color palette is only 80%, causing many HDR movies to appear flat and not fully represent the variety of colors.

Colour reproduction tests on the X75WL model, conducted in movie mode, reveal strengths and weaknesses. While movie mode offers some of the best image settings, it is not flawless. One of the most significant issues with the X75WL is the white balance, particularly for HD and 4K HDR content, where a blue hue dominates the image. This results in a noticeably cold tone throughout. The colour checker confirms these discrepancies, showing a clear shift towards cooler shades.

Regarding brightness, the contrast gamma level is generally acceptable, but the EOTF curve presents more challenges. There are noticeable problems with maintaining consistent brightness, with the image sometimes appearing too washed out or too dim. These issues affect the overall visual experience and hinder the accurate perception of content.

The Filmmaker mode on the LG UA7500 performs better than one might expect from such a budget TV, but let's not get carried away with the praise. The picture is put together quite sensibly and at first glance is not irritating; however, its weaknesses quickly start to show. This is most apparent in scenes with bright points – lamps in the background or reflections of light on the skin are clearly exaggerated. Characters' faces often look unnatural, as if they have been "burned out." Additionally, the default gamma settings brighten even the smallest details, causing the image to lose subtlety in darker areas. Nevertheless, the fact remains that, for its price range, the UA7500 in factory mode provides a decent starting point. However, it's clear that without additional correction, these issues cannot be avoided, which is why – as with other TVs – we decided to check what could be achieved after calibration.

The X75WL is one of those cases where image calibration may not lead to a dramatic transformation, but it does offer a notable improvement in colour perception. The white balance for HD and 4K content, has been significantly enhanced, eliminating the strong dominance of cooler tones. The gamma chart also appears more stable, resulting in better image quality overall. However, the main issue remains the EOTF curve, which controls brightness in 4K content. Due to the technological limitations of the television (such as the IPS panel and the absence of local dimming), a significant improvement is difficult to achieve, as the model’s capabilities are constrained. Despite these limitations, the tonality of the image has been substantially improved.

We noticed the greatest improvement when calibrating the mode intended for daily SDR content. We managed to smooth the white balance in an acceptable way and tackle the issue of excessive brightening of small elements by the gamma characteristic. As a result, the image gained the consistency and naturalness that were lacking in the factory settings. After such correction, we can confidently state that for daily television content, programs, or materials from YouTube, the LG UA7500 performs really well – especially after professional calibration. The situation is somewhat different for HDR content. Here, the calibration did allow us to tame the white balance and slightly improve brightness management, but the limitations of the design are immediately apparent. The lack of additional filters to widen the color palette means that the most vivid colors appear flat, and the image does not have the intensity we would expect from good HDR. In SDR, the UA7500 performs quite decently, but in HDR – despite corrections – it remains far behind, and this is a characteristic that one must accept when choosing this television.

The X75WL struggles with low-quality tonal transitions. The lack of any function to improve tonal gradation results in noticeable imperfections in colour transitions, which detracts from the overall image quality. However, the digital processing is commendable, with the image displayed without overscan, and relatively sharp presentation. This added sharpness may appeal to some users, though it does not compensate for the tonal transition issues.

The LG UA7500 with a VA panel has shown a really good performance in this category. The image scaling from Full HD content or even SD was surprisingly smooth. The picture looked smooth, edges weren't excessively jagged, and the television maintained a significant amount of detail, which meant that even older movies didn't lose their character. It particularly excelled with faces – there were no artificial contours or the "mask" effect, which often occurs in cheaper models. The way the television handled tonal transitions in lower-quality materials is also noteworthy. Thanks to digital processing, colors didn't blend together, and gradients looked natural and smooth. There was no intrusive image smoothing 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 X75WL features a 60 Hz panel, making it more suited for movie-watching than high-speed gaming. It is equipped with a motion smoother function called Motionflow, which allows users to adjust picture fluidity on a 10-point scale. This function adds intermediate frames, improving motion smoothness and creating a more cinematic effect by reducing choppiness. Additionally, the clarity adjustment helps reduce motion blur, making it particularly beneficial for fast-paced scenes like sports or dynamic action sequences in films. With these settings, users can fine-tune the fluidity and sharpness of motion to their preferences.

LG UA7500 is a television with a 60 Hz panel, so it’s hard to expect any awe in this category. It’s more of a screen intended for everyday content or an evening movie session rather than for following dynamic sports events or playing action games. It’s clear that the manufacturer directed this model specifically to that group of consumers – and in that regard, it performs correctly. We have the TruMotion function at our disposal, which is a motion smoother. It’s simple, has only one slider, but it can make a noticeable difference. At lower settings, the image appears more raw and cinematic, while at higher values, motion becomes smoother and more pleasing to the eye.

The X75WL is not the best television for gamers, as it lacks some key features that more demanding users expect. While it includes the Auto Low Latency Mode (ALLM) and a basic Game Bar, these are not sufficient for a truly immersive gaming experience. In this price range, features like VRR (Variable Refresh Rate) and a 120 Hz refresh rate—at least in Full HD—have become standard, but unfortunately, these are missing in the X75WL. This is a significant drawback for Sony, as the competition offers more advanced gaming features at a similar price.

LG UA7500 is a television that can be safely recommended to "casual" gamers. While it does not have a 120 Hz panel or HDMI 2.1 ports, so fully utilizing the potential of modern consoles is out of the question. However, the manufacturer has taken care to include a few extras that can make gaming more enjoyable. Notably, the Game Bar deserves mention – a very nicely designed panel where you can quickly view and change the most important settings. From this panel, we have access to features such as ALLM (automatic switching to game mode) and frame synchronization, which is 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 television leaves a positive impression.

Additionally, there is support for HGiG, which is HDR calibration mode for gaming. It sounds good, but based on testing experiences, we already know that with the UA7500, this option doesn't make much sense. The television does not handle HDR very well, 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 full immersion from the latest consoles.
