LG OLED G4 vs Sony Bravia 8 MK2

LG G4 guarantees an incredibly vibrant HDR effect, placing the television firmly at the top of the rankings. The highest model in the manufacturer's 2024 portfolio, equipped with the second generation of microlens technology (MLA), has achieved a maximum brightness level of 1474 nits in real scenes. The only area where the product of the Korean manufacturer may fall short compared to LCD televisions with Mini LED backlighting is during a full-screen scene featuring a lot of white. If we were to disregard the latter scene, the average result would be even higher. It's also worth mentioning scenes with very fine details, where each one shone at full intensity, which is not as evident in non-OLED televisions. The combination of such brightness and wide coverage of the DCI-P3 color space ensures that HDR materials are 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 to near-reference quality in films and series recorded in HDR format. In test materials such as Life of Pi and Sicario 2, the effect is absolutely stunning – details in bright parts of the image remain perfectly visible, and night scenes captivate with depth and contrast. However, it’s not perfect. Compared to its most formidable competitors, the Bravia 8 II shows a noticeable drop in brightness during full-screen, very bright scenes. When comparing peak luminance with 100% white brightness in HDR mode, the Bravia 8 II can appear two or three times dimmer than LG G5 or Samsung S95F models. This was particularly evident in a scene from the film The Meg – the screen became noticeably darker than in competitors' televisions. Despite this flaw, the Bravia 8 II's results still place it at the forefront of the market. It deserves praise for its absolutely top-notch colour gamut coverage – nearly 100% DCI-P3 and close to 90% BT.2020. These parameters allow full potential extraction from HDR content and provide a cinematic experience in the comfort of your home.

The best factory mode in terms of colour reproduction was "Filmmaker". This is the one we used during our tests. Let's check how its characteristics looked before the calibration process. Taking a closer look at the white balance first, we can notice a significant dominance of red and green colour. As a result, the image had a warm yellow tint. This is the kind of characteristic we usually observe in "Cinema", "Filmmaker", or similarly named modes. The effect of such a colour balance was clearly visible in both SDR and HDR content, which, after switching from "Standard" mode, was distinctly yellowed. Now let's move on to two graphs that are responsible for brightness characteristics, and consequently, image contrast. The first one (Gamma), representing materials with a standard colour palette, performed decently. For most of the time, the midtones and bright whites were represented very accurately, however, it noticeably lost the darkest details which blended into a black patch. On the other hand, HDR materials, represented by the EOTF curve graph, exhibited a significant drop in contrast due to a strong boost in brightness. There was also an issue with the colours themselves as seen on the "ColorChecker" graph since they were noticeably undersaturated.

Right out of the box, the Bravia 8 II performs really well. In the best IMAX® Enhanced mode, the TV manages to render colours in a pleasant and natural way, although "well" doesn’t mean "best in class" here. The white balance definitely requires adjustment – skin tones tend to lean towards slightly pink/cool tones, both in SDR and HDR content. We also noticed that the EOTF curve characteristics show a tendency to brighten the darkest parts of the image. This is likely 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's not an ideal solution.

The manufacturer has been implementing extensive support for the calibration process in their LG televisions for many years. Therefore, we used 2- and 20-point grey scale adjustments along with an advanced CMS (Color Management System) and got to work. As you can see, thanks to the procedure carried out, each of the parameters has significantly improved. The use of tools has resulted in extremely beneficial effects, which include: studio colour reproduction, recovery of details in dark areas of the image, appropriate brightness characteristics, and proper colour saturation. Thus, we have maximised our approach to the reference image, or the one that the film director saw on the preview monitor. It is worth noting that the LG G4 televisions are the only ones that allow for even deeper intervention in image quality due to the capability to calibrate with 3D LUT matrices. However, this solution is recommended only for post-production or graphic studios.

After calibration, the excessive cooling of the image caused by an overly strong boost in blue colour was primarily eliminated. The reds became deeper, and the skin tones took on a natural, healthy appearance. The actors, who previously seemed "cold," now look much livelier and more convincing on screen. However, one thing hasn't changed – the analysis of the EOTF curve still shows that the Bravia 8 II has a tendency to brighten the darkest parts of the image. It's hard to say whether this is a deliberate effect by the manufacturer or a consequence of the panel's design and software. In practice, this means that scenes that the creators wanted to leave in deep darkness can reveal more details than intended. Despite this, the reception of the image after calibration is clearly better – the warm, natural tones and realistic skin shades make viewing on the Bravia 8 II simply more pleasant to the eye.

The tested television did not perform well with content rich in tonal transitions, resulting in a strong posterisation effect. However, there is a partial remedy for this ailment. 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 high smoothing effectiveness on bright colours, though low on darker ones. We recommend primarily using the first one due to the fact that the other two interfere with directorial intentions, removing film grain.

When watching lower-quality content, the efficiency of the television during upscaling is extremely important. The image from the tested television is sharp and clear. However, attention should be paid to the jagged edges of fine details and minor issues around characters, such as the creation of a halo effect, which occurs due to the sharpening imposed by the LG G4 even when the slider is set to the lowest value, which is 0. It is worth noting that this is a change in relation 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 confirms its reputation. The proprietary XR processor can extract nearly the maximum from lower resolution materials – whether it's TV or an old movie from a DVD, the image appears clearer, with more detail and better depth. Sure, if we feed it exceptionally poor-quality material (like our archival photo with the Model), it won't work miracles, but in everyday viewing, it’s hard to find fault.

The gentle gradation feature also performs excellently. In the “Medium” setting, it effectively smooths tonal transitions, eliminating stripes on colourful and grey gradients, while not destroying film grain or fine image details. It’s this balance between delicacy and effectiveness that keeps Sony TVs 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 by connecting the LG G4 to a very powerful PC. Otherwise, we will be operating 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 who require high fluidity of image, the manufacturer has implemented a multi-level motion smoother called "TrueMotion". It 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 increment affecting the degree of smoothing, so everyone can find their sweet spot.

The LG OLED G4 panel features an average response time of 0.78 ms (which directly results from our measurements), allowing for an incredibly clear image, unattainable by LCD televisions, which have response times of even several milliseconds. This is clearly visible in the "UFO Test" images, showing the absence of any trailing blur behind the object. Furthermore, the LG OLED G4 test showed that the television offers the ability to precisely adjust motion smoothing functionality, allowing users to choose the ideal level of image interpolation. We particularly appreciated this during fast-paced action in video games, where the LG G4 performed exceptionally well, minimising any blurriness. Thanks to OLED technology, this model eliminates so-called ghosting, ensuring that the image remains sharp even in the most dynamic sports or movie scenes.

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

The LG G4 television supports all features that make up the HDMI 2.1 standard. During testing, each feature activated without any issues, which allows us to consider the television as designed for gaming. Its performance will certainly be appreciated by both console users and those connecting the LG G4 to a computer. It’s also worth mentioning the proper implementation of the HGIG (HDR Gaming Interest Group) mode, which ensures that games mastered to brightness levels beyond the maximum luminance of the LG G4 will correctly map tones, keeping the game image true to the original.

A nice touch is the presence of a special GameBar that we can bring up at any moment to check game parameters, but most importantly, to change them quickly. More importantly, turning on VRR technology does not degrade contrast, which is often a problem in televisions with local dimming or Mini LED backlighting. Of course, this is thanks to the OLED panel itself, characterised by pixel self-emissiveness. As a journalistic note, we will only mention a slight grey flicker, which, however, is somewhat normal when VRR is enabled.

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

Sony has really done its homework from previous years and in the Bravia 8 II, it has prepared a package of features for gamers that is hard to describe as anything other 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 check parameters and change settings without leaving the game. It's also worth noting how smoothly and seamlessly these features work – no delays, no strange stutter. You simply turn on the game and everything looks as it should. Unfortunately, there are a few "buts". The manufacturer still provides us with only two full bandwidth HDMI ports, so if someone has a console, a PC, and another device like a Soundbar connected via eARC, the fun begins with plugging and unplugging cables. It's also surprising that there's no support for 1440p at 120 Hz – particularly important for Xbox gamers. Overall though – this is one of those TVs that can comfortably be placed in the centre of a gaming lounge and enjoyed without major compromises.
