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

The situation is even more modest in the IPS version, where the peak brightness reaches only 250 nits. In practice, this means that there can be no real sense of HDR effect, and the materials being viewed resemble ordinary SDR. Similar to the VA case, the image behaves stably on most test screens, but in demanding scenes with fine details, the television tends to slightly dim the image. As a result, blacks appear somewhat better, but at the cost of losing detail in bright elements. The lack of additional color filters is also noticeable here. The UA7500 in the IPS version does not belong to QLEDs or PFS LED panels, and the DCI-P3 color gamut stops at 80%, which means that HDR films present themselves without much color depth and give the impression of being heavily flattened.

The HDR effect on the LG C6 is really very good. LG Display's new WOLED panel primarily brought a significant increase in brightness. In our unit we measured around 1,500 nits and, importantly, the TV can show similar values in many normal movie scenes. That gives HDR the proper impact. Bright highlights, lamps, or sunlight can be really strong, and most HDR movies simply look very impressive. Of course it's still an OLED, so brightness drops in scenes with a lot of white. The fifth scene of The Meg illustrates this well, where the C6 reached about 600-700 nits. That's still a very good result, but it also shows the new panel hasn't removed all the limitations typical of OLEDs.

Colors

When it comes to color, there is also little to complain about. The C6 covers about 99% of the DCI-P3 gamut and roughly 75% of BT.2020. In practice the colors are very saturated and, importantly, stable regardless of the scene. That's worth emphasizing, because not every TV behaves the same in this respect. In some RGB Mini LED models color saturation can depend more strongly on image brightness. Today a wider color gamut 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 generate appropriately saturated colors in most movie scenes.

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 enthusiasm. The picture is fairly well put together and at first glance does not offend, but its weaknesses quickly start to show. This is most evident in scenes with bright points — background lamps or light reflections on the skin are clearly overemphasized. The faces of the characters often look unnatural, as if they have been "blown out." Additionally, the default gamma characteristic brightens the smallest details and causes the image to lose subtlety in darker areas. That said, given its price range, the UA7500 in factory mode provides a pretty decent starting point. However, it is clear that without additional adjustments, these problems cannot be avoided, which is why — as with other TVs — we decided to check what could be achieved after calibration.

Right out of the box the LG C6 is pretty well set up, especially if you choose Filmmaker mode. In SDR material the white balance is decent, although as brightness increases it starts to lack a bit of red. The picture becomes a little cooler as a result, but it’s not such a big difference that it stands out during normal viewing. More happens in the brightness response itself. Gamma is a bit low and instead of holding at 2.4 it sits closer to 2.1–2.2 over much of the range. 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 dark room. In HDR the situation is a bit more interesting. The start of the grayscale looks very good, but from about 20–30% brightness the white balance starts to drift more and more. As brightness rises there’s more red and a noticeable lack of blue. In the brightest highlights the difference is already significant and also affects reproduction of some colors. The EOTF curve itself is handled fairly well over most of the range. The C6 only has a tendency to slightly brighten the image, which we also saw during our film comparisons. The largest deviation appears around the brightest highlights, where the TV begins to adapt the signal to the panel’s capabilities. So the out-of-the-box Filmmaker mode in HDR isn’t perfect, but overall it performs well. The biggest room for improvement is the white balance, especially at high brightness.

The biggest improvement we noticed was when calibrating the mode designed for everyday SDR content. We managed to smooth out the white balance in an acceptable way and tackle the problem of excessive brightening of small elements due to the gamma characteristic. As a result, the image gained consistency and naturalness that was lacking in the factory settings. After such correction, we can confidently state that for everyday 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, calibration allowed 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 broaden the color palette makes the most vibrant colors appear flat, and the image lacks 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 feature one has to come to terms with when choosing this television.

LG TVs have been very receptive to calibration for years, and the C6 is no exception. After adjustment the white balance was set almost perfectly, and most color errors dropped to values below 3, often even around 2. In practice this means very accurate color reproduction in both SDR and HDR. An interesting detail appeared only with the HDR brightness characteristic. On a classic EOTF chart everything looks nearly ideal, and at first glance it would be hard to find fault. Only when we measured the TV’s behavior using filters based on actual movie 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 people may even see it as a positive, because HDR looks a bit more impressive this way. From the standpoint of fidelity to the source material this isn’t ideal — some scenes are simply a touch brighter than the filmmaker intended. Interestingly, this is somewhat unusual for LG. In previous generations, the brand’s TVs typically stuck very closely to the reference tone curve after calibration. With the C6 we’re still very close to the standard, but that subtle boost in brightness is indeed noticeable in films and series.

The version with the IPS matrix performed significantly worse here. Image scaling was uneven – this was particularly noticeable in lower-quality materials, where edges became jagged and the image looked less detailed. At times, there was also a sense of slight blurriness that detracted from sharpness and made the overall presentation seem less polished than in the VA version. The tonal smoothing function turned out to be a lifesaver. At the medium setting, it worked very well – it didn't ruin the image with excessive softening, while smoothing out colors in such a way that everyday content gained consistency. The difference was especially visible with television programs or streaming materials of poorer compression quality, where the television with the function enabled presented itself much better. This is one of those features that is worth keeping active because it significantly enhances the reception of everyday materials.

The LG C6 has taken a really big step forward here. The TV uses the same processor found in the flagship G6, and in terms of image processing the two models are very similar. That’s a big plus, because in this area LG’s processor this year performs excellently. The "Smooth Gradation" feature works especially well. With heavily compressed material it can effectively hide ugly tonal transitions and artifacts that often appear, for example, in lower-quality streaming. It’s best to leave it set to "Low." Then the improvement is clear, and the TV doesn’t yet start blurring fine details. Higher levels smooth the image more, but can already remove some of the natural texture of objects on the screen. The upscaling itself also performs very well. Lower-resolution content is sharpened properly, edges look clean, and the processor quite effectively rebuilds fine details. In this regard the C6 is already very 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 difficult to expect any excitement in this category. It's more of a screen intended for everyday content or an evening movie session rather than for following dynamic sporting events or playing action games. It's clear that the manufacturer designed this model specifically for that group of viewers – and in that regard, it works properly. We have access to the TruMotion feature, which is a motion smoother. It's simple, with just one slider, but it can make a noticeable difference. At lower settings, the picture looks more raw and cinematic, while at higher values, the motion becomes smoother and more pleasant 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, sports, or consoles we'll of course use up to 120 Hz, but even then it's hard to fault the motion clarity. As you'd expect from an OLED, the panel's response time is almost instantaneous. Moving objects therefore don't leave the characteristic smears you still see on LCD TVs. This is particularly noticeable in sports and fast-paced games, where the picture remains very clean even during dynamic motion.

For movies and TV, LG also provides the TruMotion motion-smoothing system. In the user settings you'll find two separate sliders. De-Judder is mainly for low-frame-rate content, that is primarily 24 fps films and series. It can slightly reduce the characteristic judder, or be set higher if you want a much smoother image. De-Blur is useful for higher-frame-rate material, mainly sports broadcasts and 50/60 fps television.

LG UA7500 is a television that can be confidently recommended for "casual" gamers. While it lacks a 120 Hz panel and HDMI 2.1 ports, making full use of the potential of modern consoles out of the question, the manufacturer has included a few additions that can enhance the gaming experience. Notably, the Game Bar deserves mention – a very nicely designed panel that allows quick access to and modification of the most important settings. From this panel, we have access to features such as ALLM mode (automatic switching to game mode) and frame synchronization, which is VRR. The range of VRR is limited – it operates from 48 to 60 Hz – but the mere presence of this feature in such an affordable television is impressive.

Additionally, it supports HGiG, which is a calibration mode for HDR specifically for gaming. This sounds good, but based on testing experience, we already know that in the case of 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 feature turned off. This is another signal that the UA7500 is more of a screen for occasional gamers who value simplicity and comfort rather than for those looking for a complete experience from the latest consoles.

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