LG UA75006LA (IPS) vs LG OLED C6 (WOLED)

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 HDR performance of the LG C6 is really very good. LG Display’s new WOLED panel has mainly brought a significant increase in brightness. In our unit we measured around 1500 nits and, importantly, the TV can show similar values in many normal movie scenes as well. That gives HDR real punch. Bright highlights, lamps and sunlight can be genuinely intense, and most HDR movies simply look very impressive. Of course it’s still an OLED, so brightness falls in scenes with a lot of white. The fifth scene from the movie The Meg illustrates this well, where the C6 reached around 600 to 700 nits. That’s still a very good result, but it also shows the new panel hasn’t shed all the limitations typical of OLEDs.

Colours

When it comes to colours, it’s also hard to raise major objections. The C6 covers about 99% of the DCI-P3 gamut and roughly 75% of BT.2020. In practice colours are very saturated and, importantly, stable regardless of the scene. That’s worth emphasising, because not every TV behaves the same in this respect. In some RGB Mini LED models colour saturation can depend more strongly on image brightness. A wider colour gamut today is mainly offered by QD-OLED TVs and new SQD models with a new generation of quantum dots. However, the C6 still performs very strongly here and is able to produce suitably saturated colours in most movie scenes.

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.

Right out of the box the LG C6 is quite well set up, especially if you choose the Filmmaker mode. In SDR material the white balance is decent, although as brightness increases there is a slight lack of red. The image becomes a bit cooler, but not enough for it to be very noticeable during normal viewing. More is happening in the brightness characteristic. Gamma is a little low and instead of holding at 2.4, for a large part of the range it sits closer to 2.1–2.2. In practice the C6 slightly brightens midtones. Shadows are therefore more readable, but the image loses some depth compared with how it should look in a darkened room.

In HDR the situation is a bit more interesting. The start of the greyscale looks very good, but from about 20–30% brightness the white balance starts to drift increasingly. As brightness rises there is more red and a noticeable lack of blue. In the brightest sections the difference is already significant and also affects the reproduction of some colours. The EOTF curve itself is followed quite well through most of the range. The C6 only tends to slightly brighten the image, which we also saw in our film comparisons. The largest deviation appears around the brightest parts, where the TV starts adapting the signal to the panel's capabilities.

The factory Filmmaker setting in HDR is therefore not perfect, but overall performs well. The biggest area for improvement is the white balance, especially at high brightness.

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.

LG TVs have long responded very well to calibration, and the C6 is no exception. After adjustments we managed to set the white balance practically perfectly, and most colour errors fell below 3, often down to around 2. In practice this means very accurate colour reproduction in both SDR and HDR. An interesting detail only appeared with the HDR brightness response. On a classic EOTF chart everything looks almost perfect and at first glance it would be hard to find fault. Only when we measured the TV’s behaviour using filters based on real film scenes did it become clear that the C6 has a slight tendency to artificially boost image brightness.

It’s not a huge difference and many viewers may even see it as a positive, because HDR looks a bit more striking as a result. From the point of view of fidelity to the source material, however, it’s not ideal — some scenes are simply a touch brighter than the filmmaker intended. Interestingly, this is rather unusual for LG. In previous generations the brand’s TVs typically held very closely to the reference picture curve after calibration. The C6 is still very close to the standard, but that subtle brightness 'boost' can indeed be noticed in films and TV series.

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.

Here the LG C6 has taken a really big step forward. The TV uses the same processor found in the flagship G6, and in terms of image processing the two models are very close. That's a big plus, because in this area LG's processor this year performs excellently. The "Smooth Gradation" function works particularly well. With heavily compressed material it can effectively hide ugly tonal banding and artefacts that often appear, for example, in lower-quality streaming. It's best to leave it on the "Low" setting. Then the improvement is clear, and the TV doesn't yet start blurring fine detail. Higher levels smooth the image more aggressively, but can already remove some of the natural texture of objects on screen. Upscaling itself also performs very well. Lower-resolution content is properly sharpened, edges look clean, and the processor quite effectively reconstructs fine details. In that respect the C6 is really close to LG's best TVs and the differences compared with the G6 are small.

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.

The LG C6 features a panel with a maximum refresh rate of 165 Hz, which is great news especially for gamers using a powerful PC. For movies, sport and consoles we’ll of course be limited to 120 Hz at most, but even then it’s hard to fault the motion clarity. As you’d expect from an OLED, the panel’s response time is near-instant. Moving objects therefore don’t leave the characteristic smearing you still see on LCD TVs. This is especially noticeable in sport and fast-paced games, where the picture remains very clean even during dynamic movement.

For movies and TV, LG has also included a motion smoothing system called TruMotion. In the user settings you’ll find two separate sliders. De-Judder is primarily for low-frame-rate material, namely movies and TV series at 24 fps. You can use it to slightly reduce the characteristic judder or increase it if you prefer a much smoother picture. De-Blur, on the other hand, is useful for higher-frame-rate content, mainly sports broadcasts and 50/60 fps TV.

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.

LG has long focused heavily on gamers, and the C6 essentially lacks nothing important. The TV supports 4K at 120 Hz from consoles, and when connected to a PC it can even run at 165 Hz. On top of that there’s VRR from 40 to 165 Hz, ALLM and a properly functioning HGiG. Another big plus is support for Dolby Vision in games, so the Xbox Series X can use that format without giving up game mode. The package is rounded out by the Game Bar, which lets you quickly check key signal parameters and change settings without leaving your game. In terms of features alone, the C6 is one of those TVs it’s really hard to fault. Whether you play on PlayStation, Xbox or PC, practically everything you could expect from a modern gaming TV is available here.
