LG OLED G4 vs Sony Bravia 8 MK2

LG G4 guarantees an incredibly vivid HDR effect, placing the television among the very best. The equipment of the highest model in the producer's 2024 portfolio with the second generation of micro-lens technology (MLA) has achieved a maximum brightness level of 1474 nits in real scenes. The only area where the product from the Korean manufacturer may lag behind LCD televisions with Mini LED backlighting is during the full-screen scenes featuring a lot of white. If we disregard the latter type of scene, the average result would be even higher. It is also worth mentioning scenes with very fine details, where each one shines at full intensity, which is not as evident in non-OLED televisions. The combination of such brightness and wide coverage of the DCI-P3 palette makes HDR materials more engaging than ever before.

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.

The best factory mode in terms of colour reproduction was "Filmmaker". This was the one we used during our tests. Let's check how its characteristics looked before the calibration process. Looking closely at the white balance first, we can notice a significant dominance of red and green. As a result, the image had a warm yellowish hue. Such characteristics are typically observed in "Cinema", "Filmmaker" or similarly named modes. The effect of this colour balance was clearly visible in both SDR and HDR content, which after switching from "Standard" mode appeared distinctly yellow. Now, let's move on to two graphs that are responsible for the brightness characteristics and consequently the contrast of the image. The first one (Gamma), representing materials with a standard colour palette, performed decently. For most of the time, midtones and bright whites were reproduced very accurately; however, it noticeably lost the darkest details, which merged into a black blob. Conversely, HDR materials, represented by the EOTF curve graph, exhibited a significant drop in contrast due to a strong boost in brightness. The colours themselves also posed a problem, as can be seen on the "ColorChecker" graph, since they were noticeably under-saturated.

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.

The manufacturer has implemented extensive support for the calibration process in its LG televisions for many years. We therefore used 2- and 20-point greyscale adjustments, as well as an advanced CMS (Colour Management System), and got to work. As you can see, thanks to the procedure carried out, each parameter has significantly improved. The use of tools allowed for the achievement of extremely beneficial effects, which include: studio colour reproduction, recovery of details in dark areas of the image, appropriate brightness characteristics, and suitable colour saturation. This brings us as close as possible to the reference image, which is what the film director saw on the preview monitor. It is worth noting that the LG G4 televisions alone allow for even deeper intervention in image quality thanks to the ability to calibrate with 3D LUTs. However, this is a solution recommended only for post-production or graphic studios.

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.

The tested television did not perform particularly well with materials rich in tonal transitions, as a result of which we could observe a strong posterisation effect. However, there is a partial remedy for this issue. The manufacturer has equipped the LG G4 with a smoothing system called "Gentle Gradation," which we can apply at three levels: Low, Medium, and High. Each of these options guarantees quite a high effectiveness of smoothing on light colours, although it is low on darker ones. We recommend primarily using the first one, as the other two interfere with the director's intentions by removing film grain.

When watching lower-quality materials, the efficiency of the television during upscaling is extremely important. The image from the tested television is sharp and clear. However, one should pay attention to the jagged edges of fine details and minor issues around characters, such as the creation of halo effects, which occurs due to the sharpening imposed by LG G4 even when the lowest value on the slider, that is 0, is set. It is worth noting that this represents a certain change compared to the LG G3, which did not impose such strong image sharpening, even when the appropriate slider was set to position 0.

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 maximum refresh rate that we can set on the LG G4 is 144 Hz. Naturally, this is only possible when the LG G4 is connected to a very powerful PC. Otherwise, we will operate at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with high motion dynamics. For those requiring high image fluidity, the manufacturer has implemented a multi-level motion smoother called "TrueMotion". This has been divided into two separate sliders that adjust the sharpness of moving images (De-Blur) and judder (De-Judder). Both sliders can be set in the range from 0 to 10, with each level affecting the degree of smoothness, allowing everyone to find their golden mean.

The LG OLED G4 panel features an average response time of 0.78 ms (as directly derived from our measurements), enabling an incredibly clear image, unattainable by LCD televisions, which can have response times of several milliseconds. This is perfectly illustrated by the images from the "UFO Test", which show no trailing blur behind the object. Moreover, the LG OLED G4 test revealed that the television offers the ability to precisely adjust the motion smoothing function, allowing users to select the ideal level of image interpolation. We particularly appreciated this during fast-paced actions in video games, where the LG G4 performed exceptionally well, minimising any blurring. Thanks to OLED technology, this model eliminates so-called ghosting, ensuring that the image remains sharp even in the most dynamic sporting or cinematic scenes.

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.

The LG G4 television supports all the features that make up the HDMI 2.1 standard. During testing, each of them activated without the slightest problem, which allows us to consider the television as designed for gaming. Their functionality will surely be appreciated by both console users and those connecting the LG G4 to a computer. It is also worth mentioning the correct implementation of the HGIG (HDR Gaming Interest Group) mode, which ensures that games mastered to brightness levels exceeding the maximum luminance of the LG G4 will correctly map tones, and the game's visuals will remain true to the original.

A nice touch is the existence of a special GameBar, which we can call up at any moment to check game parameters, but most importantly, to change them quickly. More importantly, enabling VRR technology does not degrade contrast, which is very common in televisions that feature local dimming or Mini LED backlighting. Of course, this is thanks to the OLED panel itself, characterised by pixel self-emission. As a matter of editorial obligation, we will only mention a slight grey flicker, which is somewhat normal after enabling VRR.

In summary, the LG G4, like practically all OLED televisions, is an ideal product for all kinds of games and online competitions. With fully-fledged HDMI 2.1 connections with a full bandwidth of 48 Gbit, features such as VRR, ALLM, G-Sync, FreeSync, or gaming in HDR Dolby Vision will bring much joy.

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.
