LG OLED G4 vs SONY BRAVIA 3 II (XR35M2)

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.

Bravia 3 II is certainly not a TV that tries to impress with brightness. In our measurements it reached about 450 nits, so it falls well short of the brightest models on the market. That does not mean HDR is just a paper feature. Compared with ordinary SDR material, the brightest elements of the image can already come through noticeably, and reflections, highlights and stronger exposures have a bit more energy and stand out better from the rest of the scene. This is most obvious in simpler shots where the screen displays many bright elements. Then the Bravia 3 II can give a hint of a higher dynamic-range picture. The problem only begins with more demanding content, where much greater brightness headroom is required. There the TV quickly shows its limitations and instead of powerful, striking HDR we get only a competently rendered picture.

Colours

Bravia 3 II uses a QLED-type panel, although technically it does not use a classic quantum dot layer. Instead Sony has used a solution based on PFS phosphor, which performs a very similar role: it allows more saturated reds and greens and thus enables a much wider colour gamut. In measurements DCI-P3 coverage was around 94%, and the very wide BT.2020 around 74.4%. These are good results for this class of hardware, which mean the Bravia 3 II has no problem reproducing sufficiently saturated colours in HDR content. Colours do not look washed out, and more intense hues can look genuinely attractive.

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.

In Professional mode the Bravia 3 II already delivers a fairly good level of colour reproduction straight out of the box. In SDR the most noticeable issue is a slightly low gamma, which makes the midtones a little brighter. White balance isn't perfect either; as brightness increases the blue and red components become slightly lacking, so whites can at times take on a marginally warmer, faintly greenish tint. These are not faults that immediately catch the eye when watching a film. Average error values hover around 3, so the factory setting can be regarded as quite good. The situation is similar in HDR. Here too there is a slight lack of the blue component, so the image is marginally warmer than the reference, but the difference is not large enough to significantly interfere with normal viewing.

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, there is particularly a lot to be gained from SDR content. The white balance was set almost perfectly, the gamma practically matches the reference value, and the average colour errors fell from around 3 to about 1. That is already a level at which differences from the reference image are, in practice, very difficult to detect. The Bravia 3 II therefore shows that, despite its position in Sony’s lineup, it has quite a lot of potential for precise picture calibration. Improvements are also visible in HDR, although here it is no longer possible to avoid all the limitations of the TV itself. After evening out the colours, it is easier to notice that the EOTF curve in film content runs slightly below the reference value in places, so the Bravia 3 II gently darkens part of the image. This is not an ideal solution from a reference point of view, but in this particular TV it also has its benefits. With no local dimming and average black levels, this behaviour slightly reduces the visibility of the backlight in darker scenes and helps maintain a stronger impression of contrast. So you could say Sony partly masks the limitations of the panel this way, instead of trying at all costs to stick to the reference luminance.

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.

The Bravia 3 II is Sony's first TV to use the new MediaTek Pentonic 800 chipset, and there are a few changes in image processing. Starting with the basics. The upscaling itself is adequate. The TV can sensibly pull up lower-resolution material and does not have a strong tendency to over-emphasise jagged edges or other source imperfections. With regular broadcast TV or weaker streaming material the picture therefore remains quite pleasing. We have more reservations about the digital image processing. In this model Sony has replaced the well-known "Smooth Gradation" function with a new setting called "Digital Noise Reduction". Its role is essentially very similar: it is supposed to smooth unpleasant tonal transitions and artefacts resulting from heavy signal compression. Unfortunately, this function performs noticeably worse than before. At the "High" setting (the only one that had any visible effect) the TV can smooth away too many elements of the image at once, causing film grain to disappear and the texture of objects or even skin to start looking unnatural. Worse still, the effect is not particularly stable. When a scene contains more motion, the function's effect clearly weakens and at times it looks as if the TV stops intervening in the picture altogether. For everyday viewing we therefore would not recommend using it at a high level. It can help on a static shot, but the price is often an excessive loss of detail.

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.

Motion handling is definitely one of the Bravia 3 II's strongest points. The TV uses a 120Hz VA panel, a solution that, by nature, despite the high refresh rate, does not always cope well with motion blur. Here, however, Sony has managed to keep that problem very well under control. Fast-moving objects remain crisp, and the characteristic trails and blurring are reduced to a very low level, if not to zero. It is one of the least motion-blur-prone LCD TVs we have tested. Interestingly, in this respect the Bravia 3 II can even outperform the much more expensive True RGB flagship series, the Bravia 9 II.

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 Bravia 3 II is a very good TV for gamers, although not everything has been implemented exactly as we would like. The biggest change concerns the connectors. For the first time in a Sony TV we get as many as four full HDMI 2.1 ports with 48 Gb/s bandwidth, thanks to the new MediaTek Pentonic 800 chipset. That removes one of the issues that has plagued this manufacturer’s TVs for years. We can connect several devices at once and on each input use the device’s full capabilities, for example VRR or ALLM. There is also a simple Game Bar that lets you view key signal parameters and change a few useful settings, such as black level, when you want to improve visibility in darker parts of a game. However, there are two limitations worth knowing. The first is the lack of support for 1440p at 120 Hz. That will not be a problem for everyone, but people using that resolution on a console or PC, for example to get higher frame rates in certain games, will have to choose 1080p. We have more reservations about HGiG support. Sony does not allow you to disable the TV’s tone mapping on the Bravia 3 II, so the screen is always processing HDR content even when you would prefer to leave that task to the console. This is most obvious during HDR setup — the checkerboard pattern does not disappear at the point that corresponds to the TV’s actual capabilities. That does not mean HDR in games will look bad. You just need to approach the setup a little differently and, instead of relying on the pattern, manually set the peak brightness to around 450 nits. The issue can be worked around, but you should know about it before you start setting up the console.
