Sony Bravia 8 MK2 vs LG OLED C6 (WOLED)

Thanks to its new QD-OLED panel, the Sony Bravia 8 II can reach an astronomically high peak brightness of around 2000 nits, which translates to near-reference quality for films and series mastered in HDR. In test material such as Life of Pi or Sicario 2 the effect is simply stunning – detail in bright areas remains perfectly visible, and night scenes impress with depth and contrast. It's not perfect, though. Compared with its fiercest rivals the Bravia 8 II shows a noticeable drop in brightness on full-screen, very bright frames. If you compare peak point luminance with the 100% white level in HDR, the Bravia 8 II can be two to three times dimmer than the LG G5 or Samsung S95F. This was particularly clear in a scene from The Meg – the screen became noticeably darker than the competitors' TVs. Despite this drawback the Bravia 8 II still ranks among the market leaders. Credit is due for the absolutely top-tier coverage of colour gamuts – DCI-P3 at almost 100% and BT.2020 close to 90%. Those are the specs that let HDR content reach its full potential and deliver a cinema-like experience at home.

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.

Straight out of the box, the Bravia 8 II performs very well. In its best IMAX® Enhanced mode the TV renders colours pleasantly and naturally, though "good" here doesn't mean "best in class". The white balance definitely needs adjustment — skin tones tend to lean slightly pinkish to cool, in both SDR and HDR material. We also noticed that the EOTF curve shows a tendency to brighten the darkest parts of the image. This likely stems from the manufacturer's desire to reveal as much detail as possible, even in deep shadow. Is that a good approach? It's hard to say definitively, but one thing's certain: it's not an ideal solution.

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.

After calibration we were mainly able to eliminate the excessive coolness of the picture caused by an overly strong boost to the blue channel. Reds became deeper and skin tones took on a natural, healthy look. Actors who previously seemed 'cold' now appear much livelier and more convincing on screen. One thing hasn't changed: analysis of the EOTF curve still shows the Bravia 8 II tends to brighten the darkest parts of the image. It's hard to tell whether this is an intentional choice by the manufacturer or an effect of the panel design and software. In practice this means scenes that creators intended to remain in deep shadow can reveal more detail than intended. Despite this, the picture after calibration is clearly better, with warm, natural colours and realistic skin tones making viewing on the Bravia 8 II simply more pleasant to the eye.

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.

Upscaling and digital image processing are a real showcase for the Bravii 8 II. Sony has long been seen as a master in this area and this only confirms its reputation. The proprietary XR processor can extract almost the maximum from lower-resolution sources – whether it's broadcast TV or an old DVD movie, the picture looks crisper, with more detail and better depth. Of course, if you feed it exceptionally poor-quality material (like our archival shot of the Model), don't expect miracles, but in everyday viewing there's little to complain about.

The smooth gradation function also performs very well. On the "Medium" setting it effectively smooths tonal transitions, removing banding in colour and grey gradients, while not destroying film grain or fine image detail. It's this balance between subtlety and effectiveness that keeps Sony TVs among the best on the market in this category.

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.

Motion handling is essentially sorted on the Bravia 8 II. The OLED panel with a 120 Hz refresh rate naturally delivers a very clean, sharp picture in fast-moving scenes, so there's little to complain about. What really deserves praise, though, are its motion smoothing systems, among the best on the market. They let you precisely tailor film motion to your preferences, from subtle smoothing to an almost "soap-opera" effect, without the risk of artificial stutter, frame tearing or annoying artefacts. It's one of those features you'll appreciate both during film sessions and when watching sport.

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.

Sony has really done its homework and with the Bravia 8 II put together a package of features for gamers that’s hard to call anything other than 'almost perfect'. It has everything you expect in gear of this class – VRR, ALLM, a Dolby Vision Gaming mode, HGiG, and even a handy Game Bar that lets you quickly check parameters and change settings without leaving the game. It’s also a plus how smoothly and hassle-free these features run, with no latency and no odd stutters. You just fire up a game and everything looks as it should. Unfortunately, there are a few caveats. The maker still gives us only two full-bandwidth HDMI ports, so if you have a console, a PC and another device, for example a soundbar on eARC, you end up having to swap cables. It’s also surprising there’s no support for 1440p at 120 Hz, which is particularly important for Xbox gamers. Overall though, it’s one of those TVs you can confidently put at the centre of your gaming living room and enjoy gameplay without major compromises.

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.
