LG UA75006LA (VA) vs LG OLED G6 (G64LW, G66LS)

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 LG G6 is currently one of the brightest OLEDs on the market. Its peak brightness reaches nearly 2500 nits, and what’s best – this has a direct impact on real film scenes. The television flawlessly extracts details in the bright areas of the image. And this is regardless of whether we are talking about very small points like stars in the sky or slightly larger elements on the screen. Naturally, with full-screen, uniformly white scenes, the brightness of the G6 decreases due to the panel protection system (ABL). However, in real, varied cinematic shots, this value still hovers around 2000 nits, which can be considered an outstanding result. The coverage of the colour palette also deserves praise. The new second-generation Tandem OLED panel only brought a cosmetic change but still an improvement. The coverage of the DCI-P3 palette reaches nearly 99.5%, whereas for the ultra-wide BT.2020, it is around 84%. These are very good results, although it’s worth remembering one thing: at extremely high brightness levels, the colour volume will be lower than in Samsung Display’s QD-OLED panels due to the use of a white sub-pixel (WOLED). However, in everyday content and most films, catching this difference will be very difficult.

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.

We tested the LG G6 in the best factory mode in terms of colour fidelity, namely FILMMAKER MODE. In the case of our test unit, this mode was quite well tuned straight out of the box. In SDR content, the only issue we could point out was the white balance, which tended to drift towards warmer tones. Consequently, the image could occasionally appear slightly yellowed; however, overall, this was not an bothersome problem. The G6 performed a bit worse with HDR content. There, we noted too much blue component in the white balance, which caused the image to take on cooler hues, resulting in fairly noticeable errors. As can be seen in our ColorChecker chart, the colours indeed drifted towards these cooler registers. Nevertheless, considering the factory settings, the television displayed a perfectly decent level. We do know, however, that OLED screens – particularly those from LG – respond excellently to professional calibration, which is why we immediately went ahead with it.

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.

After professional calibration, we gained complete control over the panel, and we managed to align all parameters to nearly zero. We successfully calibrated the white balance perfectly, which eliminated the factory cool and warm tints from the screen. The effects are clear as day in the ColorChecker test – the average colour reproduction errors dropped below the critical value of 1-2. And what does that mean? PERFECT colours, without any distortion! However, as reviewers, we must point out here how the LG G6 arbitrarily manipulates brightness, for which the EOTF curve is responsible. When looking at the standard synthetic chart, it might seem that the line is quite straight. However, the situation changes when we turn on the measurement filter, which shows how the television interprets brightness in real, moving film scenes (EOTF in MOVIES). Then it becomes evident that some of the tiniest parts on the screen are slightly over-brightened by the algorithm. Of course, for the average viewer, such a deviation will be practically unnoticeable, but in the test of such an expensive screen, it is worth noting – especially since we are talking about a model that has huge aspirations to be named the best television of the year.

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.

Whatever one may say about the G6’s problems with near-black signal, it must be fairly acknowledged that it handles heavily compressed material and lower resolution content exceptionally well. All unwanted, unsightly tonal transitions are effectively reduced here by the "Smooth Gradation" feature. At the "Low" setting, the algorithm works flawlessly – effectively masking the artefacts resulting from strong compression without destroying the sharpness and details in the frame. Higher levels of this function do indeed smooth the image further, but they start to blur the real elements of object texture, which is why we recommend keeping this slider at a low setting. As for the upscaling to 4K, the processor does an excellent job – edge sharpness and detail reconstruction are at the highest level, and in this regard, the G6 does not fall behind the world leaders at all.

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.

LG G6 is an OLED television, so in the category of motion fluidity, it traditionally deserves the highest marks. The television supports very high refresh rates reaching up to 165 Hz in 4K resolution, but most importantly – on the screen, you will not notice any signs of blurring. The response time of the panel is almost instantaneous, ensuring that dynamic images remain perfectly sharp.

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.

The LG G6 is a true monster for gamers and one of the best-equipped televisions on the market in this regard. The manufacturer has not skimped on features, equipping this model with as many as four full HDMI 2.1 ports with a maximum bandwidth of 48 Gbps. This means that no matter which port you plug in your PlayStation 5, Xbox Series X, or powerful PC, you will get the absolute maximum performance from them.

The television supports a full set of gaming technologies: from VRR (Variable Refresh Rate) to AMD FreeSync Premium Pro, and even Nvidia G-Sync Compatible. On top of that, it offers remarkably low, nearly imperceptible input lag and an exceptionally well-functioning Game Optimizer panel, which allows you to monitor signal parameters in real time. Gaming on this screen, with the perfect black of OLED and impressive refresh rates, is pure pleasure.
