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

The version with an IPS panel looks even more modest, where the peak brightness barely reaches 250 nits. In practice, this means that a real sense of HDR effect is out of the question, and the materials viewed resemble rather ordinary SDR. Similar to VA panels, the image behaves stably on most test patterns, but in demanding scenes with fine details, the television has a tendency to slightly dim the image. This allows for slightly better blacks; however, this comes at the expense of losing detail in bright elements. The absence of additional colour filters is also noticeable here. The UA7500 with an IPS panel does not belong to QLEDs or PFS LED panels, and the DCI-P3 colour gamut is limited to 80%, meaning that HDR films lack significant colour depth and appear quite flattened.

The HDR performance of the LG C6 is really very good. LG Display's new WOLED panel has primarily brought a considerable increase in brightness. In our unit we measured around 1,500 nits and, importantly, the TV can deliver similar values in many typical film scenes. That gives the HDR the necessary impact. Bright highlights, lamps and sunlight can be really intense, and most HDR films simply look very impressive. Of course it's still an OLED, so brightness falls in scenes with a lot of white. This is well illustrated by the fifth scene in the film The Meg, where the C6 reached around 600 to 700 nits. That's still a very good result, but it also shows that the new panel hasn't shed all the limitations typical of OLEDs.

Colours

When it comes to colours, 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 colours are very saturated and, importantly, stable across different scenes. This is 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 palette is nowadays offered mainly 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 film 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 picture is quite well put together and does not irritate at first glance, but its weaknesses soon start to show. This is most evident in scenes with bright points – lamps in the background or reflections of light on the skin are distinctly overemphasised. Characters' faces often appear unnatural, as if they have been 'overexposed'. Additionally, the default gamma setting brightens even the smallest details, causing the image to lose subtlety in darker areas. However, it remains true that for its price bracket, the UA7500 in factory mode offers a fairly decent starting point. It is clear that without additional adjustment, it will not be possible to avoid these issues, 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 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 greatest improvement we noticed was during the calibration of the mode intended for everyday SDR content. We managed to smooth out the white balance in an acceptable way and control the issue of excessive brightening of fine details due to the gamma characteristics. As a result, the image gained the consistency and naturalness that was lacking in the factory settings. After this correction, we can confidently state 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 allowed us to tame the white balance and slightly improve brightness management, but the limitations of the design are immediately evident. The lack of additional filters expanding the colour palette means that the most vibrant colours appear flat, and the image does not have the intensity one would expect from good HDR. Therefore, in SDR, the UA7500 performs quite well, but in HDR – despite the corrections – it remains far behind, and this is a feature one must accept 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 colour errors dropped to values below 3, often even around 2. In practice this means very accurate colour reproduction, both in SDR and HDR. An interesting quirk only appeared with the luminance response in HDR. On a standard EOTF chart everything looks almost ideal and at first glance it would be hard to criticise. Only when we measured the TV's behaviour with filters based on actual film scenes did it become clear that the C6 has a slight tendency to artificially boost image brightness.

This is not a huge difference and many people may even view it positively, because HDR consequently looks a little more striking. From the perspective of fidelity to the source material this is not ideal, however, as 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 stuck very closely to the reference picture characteristic after calibration. With the C6 we are still very close to the standard, but this subtle brightness boost is indeed noticeable in films and TV series.

The version with the IPS panel performed noticeably worse here. Image scaling was uneven – this was particularly evident in lower quality materials, where edges became jagged and the image appeared less detailed. At times, there was also a slight blur that diminished sharpness and made the overall impression seem less refined than in the VA version. The solution proved to be the tonal transition smoothing function. On the medium setting, it worked very well – it did not spoil the image with excessive softening, while simultaneously smoothing colours in such a way that everyday content gained coherence. The difference was particularly noticeable with television programmes or streaming materials with poorer compression quality, where the television with the function on presented itself much better. This is one of those additions that are worth keeping active, as they significantly enhance the experience of daily content.

Here the LG C6 has taken a real step forward. 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 considerable plus, because in this area LG's processor this year performs excellently. The "Smooth Gradation" function in particular works very well. With heavily compressed material it can effectively hide ugly banding and artefacts that often appear, for example, in lower-quality streaming. It's best to leave it set to "Low". That way the improvement is clear and the TV does not yet start blurring fine details. Higher settings smooth the image more aggressively but can already remove some of the natural texture of objects on the screen. Upscaling itself also performs very well. Lower-resolution content is sharpened correctly, edges look clean, and the processor quite effectively reconstructs fine details. In this respect 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 is difficult to expect much excitement in this category. It is rather a screen designed for everyday content or an evening film screening rather than for following dynamic sports events or playing action games. It is clear that the manufacturer aimed this model at this group of consumers – and in this regard, it performs adequately. We have the TruMotion function available, which is a motion smoother. It is simple, has only one slider, but can make a noticeable difference. At the lower range, the picture looks more raw and cinematic, while at higher values, the motion becomes smoother and more pleasant to the eye.

LG C6 received a panel with a maximum refresh rate of 165 Hz, which is great news above all for gamers using a powerful PC. In films, sport or on consoles we will of course make use of up to 120 Hz, but even then it is hard to fault the motion clarity. As befits an OLED, the panel's response time is almost instantaneous. Moving objects therefore do not leave the characteristic smearing or trails that we can still see on LCD televisions. This is especially noticeable in sport and fast-paced games, where the picture remains very clean even during dynamic movement.

For films and television LG has also prepared the TruMotion motion smoothing system. In the user settings you will find two separate sliders. De-Judder primarily addresses low frame-rate content, that is mainly films and TV series at 24 fps. You can use it to slightly reduce the characteristic judder or set a higher value if you want a very smooth image. De-Blur is useful for higher frame-rate material, chiefly sports broadcasts and 50/60 fps television.

LG UA7500 is a television that can be confidently recommended to "casual" gamers. While it lacks a 120 Hz panel and HDMI 2.1 ports, so fully utilising the potential of modern consoles is out of the question. However, the manufacturer has included a few features that can enhance the gaming experience. Noteworthy is the Game Bar – a very well-designed panel where you can quickly preview and change the most important settings. From this panel, we have access to various features, including the ALLM mode (automatic switching to game mode) and frame synchronisation, namely 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 leaves a positive impression.

Additionally, there is support for HGiG, which is the HDR calibration mode for gaming. This sounds good, but from our testing experience, we know that in the case of the UA7500, this option is not particularly useful. The television does not perform very well with HDR, so paradoxically better results were achieved 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 seeking a full immersion experience with the latest consoles.

LG has long focused heavily on gamers, 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 at up to 165 Hz. There is also VRR from 40 to 165 Hz, ALLM and a properly working HGiG. A big plus is support for Dolby Vision in games, so the Xbox Series X can use that format without giving up Game Mode. It's rounded off by a Game Bar, from which you can quickly check key signal parameters and change settings without leaving the game. In terms of features, the C6 is therefore one of those TVs that is really hard to fault. Whether you're gaming on a PlayStation, an Xbox or a PC, practically everything you could expect from a modern gaming TV is available here.
