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 the new QD-OLED panel, the Sony Bravia 8 II can achieve astronomically high brightness levels of around 2000 nits, translating into nearly reference-quality for films and series recorded in HDR format. In test materials such as Life of Pi and Sicario 2, the effect is truly captivating – details in bright areas of the image remain perfectly visible, and night scenes enchant with depth and contrast. However, it is not perfect. Compared to its fiercest competitors, the Bravia 8 II shows a noticeable drop in brightness during full-screen, very bright scenes. When comparing maximum peak luminance with 100% white brightness in HDR mode, the Bravia 8 II appears even two or three times dimmer than LG G5 or Samsung S95F models. This was especially evident in a scene from the film The Meg – the screen became noticeably darker than in competing televisions. Despite this shortcoming, the results of the Bravia 8 II still place it among the top of the market. It deserves praise for its absolutely top-tier colour gamut coverage – nearly 100% DCI-P3 and close to 90% BT.2020. These parameters allow for fully extracting the potential of HDR content and providing experiences akin to those in a cinema within the comfort of 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 quite well. In the best IMAX® Enhanced mode, the television is able to render colours in a pleasant and natural way, although “good” doesn’t mean “best in class” here. The white balance definitely needs adjustment – skin tones tend to lean towards slightly pink/cool hues, both in SDR and HDR materials. We also noticed that the characteristic of the EOTF curve reveals a certain tendency to brighten the darkest parts of the image. This is probably due to the manufacturer’s desire to highlight as many details as possible even in deep shadows. Is this a good approach? It’s hard to say definitively, but we know one thing – 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, the excessive cooling of the image caused by an overly strong boost of the blue colour was mainly eliminated. The reds have become deeper, and skin tones have taken on a natural, healthy appearance. The actors, who previously seemed "cold," now look much livelier and more convincing on screen. However, one thing has not changed – the analysis of the EOTF curve still shows that the Bravia 8 II has a tendency to brighten the darkest areas of the image. It is difficult to determine whether this is a deliberate method used by the manufacturer or a result of the panel and software design. In practice, this means that scenes which the creators intended to leave in deep darkness can reveal more details than anticipated. Despite this, the image quality after calibration is clearly improved – warm, natural colours and realistic skin tones make viewing on the Bravia 8 II simply more pleasant 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 true showcase of the capabilities of the Bravia 8 II. Sony has long been regarded as a master in this field, and here it only reaffirms its reputation. The proprietary XR processor can extract nearly the maximum from lower-resolution materials – whether it's television or an old DVD film, the image appears clearer, with more detail and better depth. Of course, if we feed it exceptionally low-quality material (like our archival photo with the Model), it won't work wonders, but in everyday viewing, it's hard to find fault with it.

The gentle gradation feature also performs excellently. In the "Medium" setting, it effectively smooths tonal transitions, eliminating banding in coloured and grey gradients, while not destroying the film grain or fine details in the image. It is this balance between subtlety and effectiveness that keeps Sony televisions 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.

The smoothness of motion is practically a closed topic in the case of the Bravia 8 II. The OLED with a refresh rate of 120 Hz naturally provides a very clear, sharp image in dynamic scenes, so it's hard to complain about anything here. However, one of the best motion smoothing systems on the market truly deserves special praise. They allow precise adjustment of film smoothness to one’s own preferences – from gentle smoothing to almost a “theatrical” effect – without the risk of artificial jumps, tearing of the image, or annoying artifacts. This is one of those features that will be appreciated both during movie screenings and while watching sports.

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.

Sony has really learnt its lessons from previous years and in the Bravia 8 II has prepared a package of features for gamers that is hard to describe in any other way than "almost perfect". We have everything you'd expect from equipment of this class – VRR, ALLM, Dolby Vision Gaming mode, HGiG, and even a handy Game Bar that allows you to quickly preview parameters and change settings without leaving the game. It's also worth noting how smoothly and seamlessly these features work – no delays, no strange stutters. You simply start the game, and everything looks as it should. Unfortunately, there are a few "buts". The manufacturer still only provides us with two full-bandwidth HDMI ports, so if someone has a console, PC, and another device such as a soundbar connected via eARC, it becomes a hassle of switching cables. It is also surprising that there is no support for 1440p resolution at 120 Hz – particularly important for Xbox gamers. Overall, however – this is one of those televisions that can easily be placed in the centre of a gaming lounge and enjoyed without significant compromises.
