LG OLED G5 vs Sony Bravia 8 MK2

LG G5 with the new Tandem OLED matrix brings the biggest change in terms of the brightness of the television. And it's substantial. This is truly an astronomically bright OLED. In every scene tested – whether it was point lights or full-screen whites from the film The Meg – the 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 new feature of the Tandem OLED matrix is also the expanded colour gamut – and here the LG G5 performs almost perfectly. DCI-P3 reaches a full 100%, and BT.2020 is maintained at around 83%. These are some of the highest values currently available on the market – it's hard to find any other television that comes close to such results, unless we are talking about the best displays with QD-OLED panels. The G5 has nearly reference-quality HDR – both in terms of brightness and colour saturation. This is an OLED that can truly shine – and not just figuratively.

Thanks to its new QD-OLED panel, the Sony Bravia 8 II can achieve an astronomically high brightness of around 2000 nits, which translates into almost reference-quality performance in films and series mastered in HDR. In test material such as Life of Pi or Sicario 2 the effect is genuinely impressive: details in bright areas remain perfectly visible and night scenes charm with depth and contrast. It is not, however, perfect. Compared with its toughest rivals, the Bravia 8 II shows a noticeable drop in brightness on full-screen, very bright frames. If you compare peak point luminance with 100% white in HDR mode, the Bravia 8 II can appear two or three times darker than models such as the LG G5 or Samsung S95F. In a scene from The Meg this was particularly obvious, with the screen becoming noticeably dimmer than competing TVs. Despite this shortcoming, the Bravia 8 II still ranks among the market leaders. Its absolutely top-tier colour gamut coverage is praiseworthy: DCI‑P3 at almost 100% and BT.2020 close to 90%. These are the specifications that allow HDR content to be fully realised and deliver cinema-like experiences at home.

Our test unit, the LG G5, struggled with certain issues in the factory Filmmaker mode. And although most people might have found the picture acceptable, we knew that this television was capable of much more. This mode had a clear excess of blue tint in the white balance, resulting in a significantly cooled image – particularly in HDR modes, where there was additionally a lack of red. The picture appeared cold, and its sharpness was artificially boosted and unnatural. Another significant issue was the brightness characteristics. In SDR content, the situation wasn't the worst, aside from a slight dimming of the entire image. However, it performed 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 tool for professionals for colour calibration), so we decided to make use of its professional capabilities and see what it could really do. Because although it wasn't tragic even before calibration, the potential of this television definitely deserved more.

Straight out of the box the Bravia 8 II performs really well. In its best IMAX® Enhanced mode the TV can reproduce colours in a pleasant, natural way, although "good" here does not mean "best in class". The white balance definitely needs adjustment, as skin tones tend to shift slightly towards pinkish/cool hues in both SDR and HDR content. We also noticed that the EOTF curve tends to brighten the darkest parts of the image. This is likely the manufacturer's attempt to reveal as much detail as possible even in deep shadows. Is that a good approach? It's hard to say definitively, but one thing is clear: it is not an ideal solution.

After performing the calibration process using professional tools, we can confidently state that the LG G5 offers nearly 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 television still has a tendency to slightly dim the smallest elements of the image, in practice this does not negatively affect the overall impression. Kudos to LG, as once again they provide the user with enormous possibilities for adjusting their display – and this, combined with the very good parameters of the panel itself, results in an image that is truly hard to beat.

After calibration we mainly managed to eliminate the excessive cooling of the image caused by an overly strong boost to the blue channel. Reds became deeper and skin tones acquired a natural, healthy look. Actors who previously seemed 'cold' now appear much more lively and convincing on screen. One thing has not changed, however: analysis of the EOTF curve still shows that the Bravia 8 II tends to brighten the darkest parts of the image. It is hard to say whether this is an intentional move by the manufacturer or a result 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 that, image quality after calibration is clearly better, and the warm, natural colours and realistic skin tones simply make watching on the Bravia 8 II more pleasing to the eye.

Upscaling and digital image processing in the LG G5 are quite impressive. The television handles lower quality content very well, especially when the "Smooth Gradation" feature is set to a low level. In this mode, it effectively removes unwanted artifacts and issues with visible tonal transitions. It may also slightly smooth out some desirable details, such as the subtle texture of clothing or skin, but importantly – it does not remove film grain, so it's difficult to speak of a serious compromise here. This is one of those options that is definitely worth enabling.

The G5 also performs well with upscaling, which improves the quality of older materials. The test image with the model looked really solid – slight jaggedness was visible, but that's an effect that cannot be completely avoided. Additionally, there were no problems with overscan, which – contrary to appearances – is not at all obvious, even in 2025.

Upscaling and digital image processing are a real showcase of the Bravia 8 II's capabilities. Sony has long been regarded as a master in this field, and this only confirms that reputation. Sony's proprietary XR processor can pull almost all the detail out of lower-resolution sources, whether it's television or an old DVD movie the picture looks sharper, with more detail and greater depth. Of course, if you feed it exceptionally poor-quality material (such as our archival photo of the Model), it won't work miracles, but for everyday viewing there's little to complain about.

The gentle gradation function also performs excellently. On the 'Medium' setting it effectively smooths tonal transitions, eliminating banding in colour and grey gradients while not destroying film grain or fine image details. It is precisely this balance between subtlety and effectiveness that keeps Sony's 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 165 Hz refresh rate panel, and this, combined with the instant response time of the OLED matrix, delivers incredible results. The image does not tear or stutter like on traditional LCD televisions. Like most LG models, the G5 is equipped with a motion smoother, which can be useful when watching films – we are, of course, referring to the TruMotion mode. 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 stuttering or lean towards a more fluid, television-like effect.

Motion smoothness is, in the case of the Bravia 8 II, practically a closed matter. A 120 Hz OLED naturally delivers a very clean, sharp picture in fast-moving scenes, so there's little to complain about. Particular praise, however, is due to its motion-smoothing systems, which are among the best on the market. They let you precisely tailor the motion of films to your own preferences, ranging from subtle smoothing to an almost "theatrical" effect, without the risk of artificial judder, image tearing or annoying artefacts. It's one of those features you'll appreciate both during film screenings and when watching sport.

Features for gamers? Perfect. That should be sufficient for you to know what level we are dealing with here. The G5 is a television designed with gamers in mind, so we will find literally everything you could expect from a gaming screen. There is a Game Bar, there is 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 television supports variable refresh rate (VRR), automatic low latency mode (ALLM), and also correctly handles HDR in games thanks to the HGiG function. All of this adds up to one of the best sets of gaming features available on the market. Well done, LG.
