LG OLED C6 (WOLED) vs Sony BRAVIA 7 II

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 Sony Bravia 7 II handles HDR very well and, above all, is simply a bright television. In the correct viewing mode, Professional, we measured around 2,000 nits of peak brightness, so the panel’s capabilities are truly significant. Of course, with Mini-LEDs a test pattern result is only part of the story, because a lot still depends on how the TV controls the backlight in real scenes. Here Sony’s algorithms perform very well. Depending on the scene, the brightness we measured in films ranged from roughly 1,100 to as much as 1,700 nits. That’s already a level at which HDR has proper punch and bright highlights can be genuinely impressive. It isn’t perfect in every situation, though. With small bright elements on a very dark background the Bravia 7 II clearly favours maintaining good blacks, which can cause their brightness to drop to around 500 nits. It still looks good, but you can see the TV does not always manage this without compromise.

Colours

The second thing that has a huge impact on HDR is, of course, colour. And this is precisely where True RGB technology was meant to bring one of the biggest changes. Looking at the panel’s capabilities alone, the Bravia 7 II performs very well. We measured about 98% DCI-P3 coverage and 88% BT.2020, so the potential to show strongly saturated colours is really large. In RGB TVs, however, the situation is a bit more complex. When we repeated the same measurements with a film background applied, palette coverage fell to around 92% DCI-P3 and 78% BT.2020. Those are still good figures, especially for an RGB Mini-LED TV, but they clearly show that the final result largely depends on how the algorithms control the three backlight colours. In most scenes the Bravia 7 II handles this well and colours retain high saturation. The biggest differences are visible in shades of blue, where samples begin to deviate more noticeably from reference values and coverage is weaker than for the other primary colours. True RGB therefore offers genuinely greater potential here, but, as with brightness, much depends on what is happening on screen.

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.

To evaluate the factory colours we chose the Professional mode, because it performs best among the available settings. However, it is not perfect. In SDR the white balance drifts slightly towards magenta, making some scenes look a little warmer and less neutral than they should. A bigger problem is the gamma, which sits closer to 2.5 than to 2.4. This makes the image a bit too dark in places, particularly in the midtones. In HDR the situation is better. As brightness increases a little too much red appears, but this is not an issue that is highly noticeable during viewing. Overall the Professional mode is a good starting point, although you can get a bit more out of it after calibration.

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.

After calibration the Bravia 7 II can look decidedly better. Above all, we managed to set the white balance very well, both in SDR and HDR. Gamma can also be improved, which after correction runs very close to the reference value. And in fact, for most users these changes will have the greatest impact on the picture. There is, however, a limitation when it comes to the colours themselves. In the Bravia 7 II Sony does not provide access to a classic CMS that would allow us to correct individual hues separately. A lot is therefore left in the hands of the algorithms controlling the True RGB backlight. If the TV misrepresents a particular colour, we are not always able to do anything about it. In our measurements this is most visible in certain reds and blues, where errors can still be quite large. This does not, however, undermine the point of calibration itself. Correctly setting the white point and gamma strongly affects the whole picture, so even without the ability to precisely correct every colour the difference compared with the factory settings is noticeable.

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.

Scaling and digital processing are among the strongest points of the Bravia 7 II and one of the bigger reasons to choose Sony over the competition. The manufacturer has been handling digital image processing well for years, and it shows here too. First and foremost, the 'Smooth Gradation' function works very well and can smooth out weak tonal transitions in lower-quality material. The safest setting is Low, but we would comfortably recommend Medium as well. The effect is stronger then, yet the TV still treats details very gently. Some fine details may be slightly smoothed, but Sony does this much more subtly than many other brands. The upscaling itself also performs very well. Lower-resolution material is well upscaled to 4K, the image looks clean and retains a lot of detail. Of course the TV will not magically turn native HD material into true 4K, but what can be extracted from such a source is handled really well by the Bravia 7 II.

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.

The Bravia 7 II uses a 120 Hz panel, so in terms of motion handling it delivers everything you would expect from a TV of this class. With sport or games at 120 fps, the picture is suitably smooth, and for films Sony provides an extensive motion interpolation system. You can therefore adjust the interpolation level separately and decide whether you want to preserve a more cinematic character to the motion or obtain noticeably smoother movement. The issue of motion blur itself is a little worse. The VA panel used is not among the fastest, and you can notice a slight trail behind moving objects, particularly on darker backgrounds. It is not at a level that greatly bothers during normal viewing, but last year’s Bravia 7 fared better in this respect and had a noticeably faster panel.

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.

Bravia 7 II has basically everything you’d expect today from a good console TV. It supports 4K at 120 Hz, VRR from 48 to 120 Hz and ALLM, so when you start a game the TV automatically switches to a low-latency mode. It also has properly working HGiG, which means that after configuring HDR on the console the TV won’t try to brighten the image further on its own. You just need to remember to turn off tone mapping in the TV’s menu. Dolby Vision in game mode is also a plus, especially useful for Xbox owners. Sony adds its own Game Menu. From it you can quickly check key signal information, verify VRR operation or change gaming-related settings without digging through the whole TV menu. The only thing missing from the feature list is support for 1440p at 120 Hz.

Our biggest reservation is not really about the functions themselves, but about the connectors. The Bravia 7 II has four HDMI ports, but only two of them support full HDMI 2.1 at 48 Gbps. One of those is also an eARC port. So if you connect a soundbar or AV receiver to the TV via HDMI, in practice you’re left with only one full HDMI 2.1 for a console or PC. With a single console that’s no problem, but with a PS5, an Xbox and an audio setup it starts to get tight. And this is hard to excuse for Sony. In cheaper TVs two HDMI 2.1 ports can still be acceptable, but in a model of this class, especially in 2026, we would expect a full set of four such ports.
