LG OLED G5 vs Sony Bravia 8 MK2

LG G5 with its new Tandem OLED panel brings the biggest change in terms of TV brightness. And it’s substantial. This is a truly astronomically bright OLED. In every scene tested – whether it's point lights or full-screen whites from the movie The Meg – brightness on the G5 exceeded 2000 nits. Just a year ago, such values on an OLED were simply unimaginable. And here we are – the G5 is approaching, and at times even surpassing, the best Mini-LEDs on the market. A novelty in the Tandem OLED panel is also the expanded colour gamut coverage – and here the LG G5 performs almost perfectly. DCI-P3 achieves a full 100%, while BT.2020 hovers around 83%. These are some of the highest values currently available on the market – it's hard to find any other TV that comes close to such results, unless we're talking about the best displays with QD-OLED panels. The G5 has almost reference-level HDR quality – both in terms of brightness and colour saturation. This is an OLED that can truly shine – and not just metaphorically.

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.

Our test unit LG G5 had some issues in the factory Filmmaker mode. While the picture might have seemed fine to most people, we knew this TV could do much more. This mode had a noticeable excess of blue tint in the white balance, resulting in a strongly cooled image – especially in HDR modes, where there was additionally a lack of red. The image appeared cold, and its sharpness was artificially boosted and unnatural. Another significant problem was the brightness characteristics. In SDR content, the situation wasn't the worst, aside from a slight dimming of the entire image. However, it fared much worse in HDR materials – due to improper brightness management, the smallest details could completely disappear from the image, while larger, bright elements looked overexposed and lacking in gradation. Fortunately, the G5 supports calibration using 3D LUT (a professional tool for colour calibration), so we decided to take advantage of its professional capabilities and see what it was really capable of. Because while it wasn't terrible even before calibration, the potential of this TV definitely deserved more.

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.

After completing the calibration process with professional tools, we can confidently state this – the LG G5 offers almost reference-quality image. Most of the errors related to white balance and the ColorChecker test are below a value of 2, which is a phenomenal result, practically imperceptible to the human eye. And while one could still nitpick that in HDR films the TV still has a tendency to slightly dim the smallest elements of the image, in practice this does not negatively affect the overall reception. Hats off to LG, as once again they provide users with enormous display settings options – and this, combined with very good parameters of the panel itself, results in an image that is truly hard to beat.

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.

Upscaling and digital image processing in the LG G5 performs very well. The television handles lower quality content excellently, especially when the "Smooth Gradation" feature is set to a low level. In this mode, it effectively removes undesirable artifacts and issues with visible tonal transitions. It may also slightly smooth out some desirable details, like the subtle texture of clothing or skin, but importantly – it does not remove film grain, so it's hard to talk about a serious compromise here. This is one of those options that is actually worth turning on.

The G5 also does well with upscaling, which is improving the quality of older materials. The test image with the model looked really solid – slight jaggedness was visible, but that's an effect that can't be completely avoided. On the plus side, there were no overscan issues, which – contrary to appearances – is not obvious, even in 2025.

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.

The motion smoothness on the LG G5 is simply phenomenal. The television is equipped with a panel featuring a 165 Hz refresh rate, and this combined with the instantaneous response time of the OLED matrix delivers incredible results. The image doesn’t judder or blur like on traditional LCD televisions. Like most LG models, the G5 comes with a motion smoother, which can be handy when watching movies – we’re talking about the TruMotion mode, of course. With the “De-Blur” and “De-Judder” sliders, we can adjust the smoothness of older materials according to our own preferences, whether we want to maintain the characteristic film jitter or lean towards a more fluid, television-like effect.

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.

Features for gamers? Perfect. That should be enough for you to know what level we’re dealing with here. The G5 is a TV designed for gamers, so you'll find literally everything you might expect from a gaming screen. There's Game Bar, support for high resolutions with high refresh rates - that is, 4K at 120 Hz, and even more, as the panel has a refresh rate of 165 Hz (which PC gamers will benefit from). The TV supports variable refresh rate (VRR), automatic low latency mode (ALLM), and also properly handles HDR in games thanks to the HGiG feature. All of this adds up to one of the best gaming feature sets available on the market. Well done, LG.

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.
