LG OLED C6H (TANDEM OLED) vs Sony BRAVIA 7 II

And the biggest advantage of the Tandem OLED panel is most obvious with HDR. The C6H's brightness is simply very high and, in our measurements across most film scenes, hovered around 1,900 to 2,300 nits. That's the kind of level at which bright highlights, the sun or small light sources can look truly spectacular. The scene that impressed us most was the fifth scene from the film The Meg. It's particularly demanding for OLEDs because almost the entire screen is extremely bright. Even so, the C6H reached about 1,650 nits in that scene. By comparison, the standard C6 with a classic WOLED panel managed roughly 600 to 700 nits at the same point. So we're talking about more than double the brightness, and in places the difference approaches three times as much. And that's probably the best example of what Tandem OLED delivers. It's not just a higher score on a small test window. The C6H can maintain very high brightness even when much more of the screen is illuminated. That gives HDR a much wider dynamic range, and in this respect the C6H is considerably closer to flagship OLEDs than to typical mid-range models.

Colours

Tandem OLED also brings improvements in colour. DCI-P3 coverage remains virtually complete at around 99%, while in the much wider BT.2020 colour space we measured about 82–83%. That's roughly 7 percentage points more than the standard C6. In everyday viewing this won't be a difference you notice in every scene, because most films don't use such a wide palette. However, when very highly saturated colours appear, the C6H has noticeably greater capability, especially with reds. Reds benefit the most, becoming deeper and more saturated. It's still not at the level of the best QD-OLED panels or SQD TVs, but for a WOLED panel the result is really very good.

Sony Bravia 7 II handles HDR very well and, above all, is simply a bright television. In the correct viewing mode for watching, Professional, we measured about 2,000 nits of peak brightness, so the panel’s capabilities are truly large. Of course, in Mini-LED sets a test-pattern result is only part of the story, because much still depends on how the TV controls the backlight in real scenes. Here Sony’s algorithms perform really well. Depending on the scene, the brightness we measured in films ranged from about 1,100 to as much as 1,700 nits. That’s a level at which HDR has proper punch and bright highlights can be genuinely impressive. It’s not perfect in every situation. With small bright elements on a very dark background, the Bravia 7 II clearly prioritises maintaining good black levels, so their brightness can fall to around 500 nits. It still looks good, but it’s clear the TV doesn’t always manage this without compromise.

Colours

The second thing that has a huge impact on HDR is, of course, colour. And this is where True RGB was meant to deliver one of the biggest changes. Looking at the panel’s capabilities alone, the Bravia 7 II performs very well. We measured roughly 98% DCI-P3 coverage and 88% BT.2020, so the potential for showing highly saturated colours is substantial. In RGB TVs the matter is a bit more complex. When we repeated the same measurements with a film-like background applied, gamut coverage dropped to about 92% DCI-P3 and 78% BT.2020. Those are still good numbers, especially for an RGB Mini-LED TV, but they show that the final result largely depends on how the algorithms drive the three backlight colours. In most scenes the Bravia 7 II handles this well and colours retain strong saturation. The biggest differences are visible in blue shades, where samples start to deviate more noticeably from the reference values and coverage is weaker than for the other primaries. True RGB therefore offers genuinely greater potential, but, as with brightness, a lot depends on what’s actually happening on screen.

Right out of the box the LG C6 is pretty well set up, especially if you select Filmmaker mode. In SDR content the white balance is good, although as brightness increases it starts to lack red slightly. This makes the picture a bit cooler, but not enough to be very noticeable during normal viewing. More is going on in the luminance response. Gamma is a bit low and instead of holding at 2.4 it sits closer to 2.1–2.2 across a large part of the range. In practice the C6 slightly brightens midtones. Shadows are therefore more readable, but the image loses a little 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 around 20–30% brightness the white balance starts to drift more strongly. As brightness increases red builds up and blue becomes noticeably lacking. In the brightest parts the difference is already significant and also affects the reproduction of some colours. The EOTF curve itself is handled quite well across most of the range. The C6 only has a tendency to slightly brighten the picture, which we've already seen in our film comparisons. The biggest deviation appears around the brightest sections where the TV starts to adapt the signal to the panel's capabilities.

So the factory Filmmaker setting in HDR is not perfect, but overall 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 presets. It's not perfect. In SDR the white balance is slightly biased toward magenta, so some scenes look a little warmer and less neutral than they should. A bigger issue is the gamma, which sits closer to 2.5 than 2.4. As a result the image is a bit too dark in places, especially in the mid-tones. In HDR the situation is better. As brightness increases there's a little too much red, but it isn't something that really jumps out while watching. Overall the Professional mode is a good starting point, though you can get a bit more out of it with calibration.

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

It isn’t a huge difference and many people may even see it as a positive, since HDR looks a bit more punchy. From the point of view of fidelity to the source material it’s not ideal, though — some scenes are simply a touch brighter than the filmmaker intended. Interestingly, this is quite atypical for LG. In previous generations, this brand’s TVs usually stuck very closely to the reference picture characteristics after calibration. With the C6 we’re still very close to the standard, but that subtle boost in brightness can indeed be noticed in movies and TV shows.

After calibration the Bravia 7 II can look significantly better. First and foremost, we managed to set the white balance very well in both SDR and HDR. Gamma can also be improved, and after correction it runs very close to the reference value. For most users those changes will have the biggest impact on the picture. There is, however, a limitation with the colours themselves. On the Bravia 7 II Sony does not provide access to a traditional CMS that would let us adjust individual hues separately. Much is left to the algorithms controlling the True RGB backlight. If the TV reproduces a specific colour inaccurately, we are not always able to do anything about it. In our measurements this is most apparent in parts of the reds and blues, where errors can still be quite large. That does not, however, undermine the value of calibration. Correctly setting the white point and gamma strongly affects the whole picture, so even without the ability to precisely correct every colour the difference from the factory settings is noticeable.

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 similar. That's a big plus, because in this area LG's processor this year performs excellently. The 'Smooth Gradation' function works especially well. With heavily compressed material it can effectively hide unsightly tonal banding and artefacts that often appear, for example, in lower-quality streaming. It's best left on the 'Low' setting. That way the improvement is clear, and the TV doesn't yet start to blur fine details. Higher levels smooth the picture more, but can begin to 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 this respect the C6 is already really close to LG's top 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 Sony's biggest advantages over the competition. Sony has for years excelled at digital image processing, and it's clear here too. Above all, the 'Smooth Gradation' function works very well, smoothing weaker tonal transitions in poorer-quality content. The safest setting is low, but we'd comfortably recommend medium as well. The effect is stronger, and the TV still handles fine detail very delicately. Some minor details may be slightly smoothed, but Sony does it much more subtly than many other brands. Upscaling is also very good. Lower-resolution content is nicely upscaled to 4K; the image looks clean and retains a lot of detail. Of course the TV won't magically turn native HD into true 4K, but the Bravia 7 II does very well with what can be pulled from such a source.

The C6H with a Tandem OLED panel can also run at a refresh rate of up to 165 Hz. PC gamers will get the most out of that, of course, because with consoles, films or sport we're still looking at a maximum of 120 Hz. The panel itself performs excellently in motion. OLED pixels respond almost instantly, so even with fast-moving objects you don't see the usual trailing. The picture stays clean both when watching sport and in fast-paced games.

If you prioritise smoothness over motion clarity, TruMotion is available. LG lets you adjust two parameters separately. De-Judder mainly works with films and series shot at 24 fps and reduces their characteristic judder. De-Blur is intended for 50/60 fps content, so it's mainly useful when watching sport or TV.

The Bravia 7 II uses a 120 Hz panel, so in terms of motion handling it delivers everything you'd 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 advanced motion interpolation system. You can therefore adjust the level of interpolation separately and choose whether to retain a more cinematic motion or achieve noticeably greater smoothness. Motion blur itself is a bit worse. The VA panel used isn't among the fastest, and moving objects can show a slight trailing, especially against darker backgrounds. It's not at a level that will seriously disturb normal viewing, but last year's Bravia 7 was better in this regard and had a noticeably faster panel.

The C6H offers virtually a full gaming feature set. On consoles you can easily use 4K at 120 Hz, while PC users can push the refresh rate up to 165 Hz. The TV also supports VRR from 40 to 165 Hz, ALLM and a correct implementation of HGiG. Dolby Vision is available in game mode too, which remains a big plus for Xbox owners. All the key info can be seen in the Game Bar, which provides quick access to VRR settings and the current signal parameters. The tandem OLED doesn’t change the actual feature set for gamers, but with such high panel brightness HDR games can look even more impressive. Functionally, the C6H is simply a very complete TV for consoles and PC.

Bravia 7 II has pretty much everything you'd want from a good console TV today. 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 low-latency mode. HGiG works correctly, so once you configure HDR on the console the TV won't try to brighten the image on its own. Just remember to turn off tone mapping in the TV's menu. Another plus is Dolby Vision in game mode, which will be especially useful for Xbox owners. Sony also includes its own Game Menu, where you can quickly view key signal info, check VRR or change gaming settings without digging through the full TV menu. The only thing missing from the feature list is support for 1440p at 120 Hz. Our biggest complaint is not really about the features but the connectors. The Bravia 7 II has four HDMI ports, but only two of them support full HDMI 2.1 with 48 Gbps bandwidth. One of those is also the eARC port. So if you connect a soundbar or AV receiver via HDMI, in practice you only have one full HDMI 2.1 left for a console or PC. With a single console that's fine, but with a PS5, an Xbox and an audio setup it starts to feel cramped. That's hard to justify from Sony. In cheaper TVs two HDMI 2.1 ports can still be accepted, but in a model of this class, especially in 2026, we'd expect all four ports to be HDMI 2.1.
