LG OLED G4 vs SONY BRAVIA 3 II (XR35M2)

The LG G4 excels in delivering an incredibly vivid HDR experience, positioning it as one of the best models in its class. Equipped with second-generation Micro Lens Array (MLA) technology, it achieves a remarkable peak brightness of 1474 nits in real-world scenes. While it may not match Mini LED-backlit LCD TVs in full-screen white scenes, the overall performance is outstanding. The fine details in HDR content shine brightly, a distinct advantage of OLED technology over non-OLED displays. With this impressive brightness and wide DCI-P3 colour gamut coverage, HDR content is brought to life with unmatched engagement and immersion.

Bravia 3 II is certainly not a TV that tries to impress with brightness. In our measurements it reached about 450 nits, so it's far from the strongest designs on the market. That said, HDR here is not just a paper feature. Compared with regular SDR material, the brightest parts of the image can already punch through, and reflections, highlights, or stronger exposures have a bit more energy and stand out better from the rest of the scene. You can see this best in simpler shots where many bright elements appear on screen. Then the Bravia 3 II can give a hint of a higher-dynamic-range picture. The problem only starts with more demanding content, where much greater brightness headroom is needed. There the TV quickly shows its limits and instead of strong, striking HDR we get only a correctly rendered picture.

Colors

Bravia 3 II uses a QLED-type panel, although technically it does not use a traditional quantum-dot layer. Instead Sony applied a PFS phosphor-based solution that serves a very similar role: it allows for more saturated reds and greens and thus lets the TV display a much wider color gamut. Measurements showed about 94% coverage of the DCI-P3 gamut and about 74.4% of the very wide BT.2020. Those are good results for this class of hardware, meaning the Bravia 3 II has no problem showing adequately saturated colors in HDR content. Colors don't look washed out, and the more intense shades can look really attractive.

Before calibration, the "Filmmaker" mode on the TV had a noticeable red and green colour dominance, resulting in a warm-yellow hue across both SDR and HDR content. This warm tone, typical of modes like "Cinema" and "Filmmaker," led to a yellowish cast that was evident when switching from the "Standard" mode.

Looking at the brightness characteristics, the Gamma chart showed decent performance for mid-tones and bright whites, but it struggled with the darkest details, which tended to merge into a black blob. HDR content, as represented by the EOTF curve chart, displayed a drop in contrast due to excessive brightness, which overshadowed fine details and negatively affected the overall image quality. Additionally, the "ColourChecker" chart revealed that colours were under-saturated, contributing to a less accurate and vibrant visual experience.

This provided a good foundation to build on, but calibration was needed to bring out the full potential of the "Filmmaker" mode and address these issues.

In Professional mode the Bravia 3 II, straight out of the box, delivers a fairly good level of color reproduction. In SDR the most noticeable issue is a slightly low gamma, which makes the midtone areas a bit brighter. White balance is not perfect either; as brightness increases there is a slight lack of blue and red, so whites can sometimes take on a slightly warmer, mildly greenish tint. However, these are not errors that immediately stand out while watching a movie. Average error values hover around 3, so the factory preset can be considered quite good. The situation is similar in HDR. Here again there is a slight deficiency in the blue component, so the image is a touch warmer than the reference, but the difference is not large enough to be significantly distracting during normal viewing.

The manufacturer has been offering extensive support for the calibration process in its LG televisions for many years. Therefore, we used 2- and 20-point grayscale adjustments along with an advanced CMS (Colour Management System) to optimise the display. As shown, the calibration procedure greatly improved each parameter. The results included studio-quality colour reproduction, enhanced detail in dark areas, corrected brightness characteristics, and accurate colour saturation. This led to a near-perfect match with the reference image—the one the film director saw on the preview monitor. It’s also worth mentioning that LG G4 televisions are unique in offering even deeper image adjustments through 3D LUT matrices, a feature primarily suited for post-production or graphics studios.

After calibration you can get a lot out of SDR content. The white balance was set almost perfectly, gamma practically matches the reference value, and average color errors fell from around 3 to about 1. That's a level at which differences from the reference image are, in practice, very hard 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 tuning. Improvements are also visible in HDR, although here you can no longer work around all of the TV's limitations. After equalizing the colors it's easier to notice that the EOTF curve in film material runs slightly below the reference value in places, meaning the Bravia 3 II slightly darkens part of the image. That's not ideal from a reference standpoint, but in this particular TV it also has an advantage. With no local dimming and average black levels, this behavior slightly reduces the visibility of the backlight in darker scenes and helps maintain a greater sense of contrast. So you could say Sony partially masks the limits of the panel that way, rather than trying at all costs to stick to the reference luminance.

The LG G4 does not perform well with materials rich in tonal transitions, leading to a pronounced posterization effect. However, the manufacturer has included a smoothing system called "Gentle Gradation," with three levels: Low, Medium, and High. These settings are effective at smoothing bright colours, though less so for darker tones. It is recommended to use the Low setting, as the higher levels can distort the director's intentions by removing film grain.

When it comes to upscaling lower-quality material, the television's performance is quite good, delivering a sharp and clear image. However, attention should be paid to the jagged edges of fine details and the occasional halo effect around figures. This occurs due to the sharpening imposed by the LG G4, even when the lowest setting is selected (0). This is a noticeable change from the LG G3, which did not apply such strong sharpening, even at setting 0.

The Bravia 3 II is Sony’s first TV to use the new MediaTek Pentonic 800 chipset, and you can see a few changes in image processing. Starting with the basics: upscaling is solid. The TV can sensibly upscale lower-resolution material and doesn’t have a strong tendency to overemphasize jagged edges or other source imperfections. With regular broadcast TV or lower-quality streaming the picture remains quite pleasing. We have more reservations about the digital image processing. In this model Sony replaced the well-known "Smooth Gradation" feature with a new setting called "Digital Noise Reduction." Its role is essentially the same: to smooth unpleasant tonal transitions and artifacts caused by heavy compression. Unfortunately, this feature performs noticeably worse than before. At the "Large" setting — the only one that noticeably affected the picture — the TV can smooth away too many image elements at once, causing film grain to disappear and surface textures or even character skin to start looking unnatural. Worse, the effect is not very consistent. When a scene contains more motion the function’s effect weakens significantly and at times it looks as if the TV stops intervening in the image altogether. For everyday viewing we therefore don’t recommend using it at a high level. It can help on a static shot, but the price is often too much loss of detail.

The LG G4 offers a maximum refresh rate of 144 Hz, achievable when connected to a powerful PC. For most users, however, the TV operates at a maximum of 120 Hz, ideal for watching sports or other content with fast motion. To improve image fluidity, the television includes the "TrueMotion" motion smoothing system, which features two separate sliders: De-Blur (for the sharpness of moving images) and De-Judder (for judder reduction). These sliders allow users to adjust the level of smoothing between 0 and 10, ensuring everyone can find the ideal setting.

With a response time of 0.78 ms, the LG G4 delivers exceptionally clear images, outperforming LCD televisions, which can have much slower response times. This results in no trailing blur behind moving objects, as shown in the "UFO Test." The TV also provides precise control over motion smoothing, which is especially beneficial during fast-paced video game sequences. Thanks to OLED technology, the G4 eliminates ghosting, ensuring a crisp and clear image even during the most dynamic sports or action scenes.

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

The LG G4 TV supports all the features encompassed by the HDMI 2.1 standard, making it a gaming powerhouse. During testing, every feature activated seamlessly, ensuring a smooth experience for both console gamers and PC users. Notably, the HGIG mode (HDR Gaming Interest Group) is implemented correctly, allowing games mastered to brightness levels higher than the TV’s maximum luminance to map tones accurately, preserving the game’s original visual integrity.

A notable highlight is the dedicated GameBar, which can be accessed at any time to quickly check or adjust game settings. More importantly, enabling VRR (Variable Refresh Rate) does not compromise contrast—a common issue in TVs with local dimming or Mini LED backlighting. This is thanks to the OLED panel’s self-emissive pixels, which maintain consistent contrast. However, a slight grey flicker may appear when VRR is enabled, though this is standard across OLEDs.

In summary, the LG G4, like most OLED TVs, is ideal for gaming and online competitions. Its HDMI 2.1 ports offer a full 48 Gbps bandwidth, supporting features such as VRR, ALLM (Auto Low Latency Mode), G-Sync, FreeSync, and HDR Dolby Vision gameplay, ensuring an exceptional gaming experience.

Sony Bravia 3 II is a very good TV for gamers, although not everything has been handled the way we'd like. The biggest change concerns the connections. For the first time in a Sony TV we get four full HDMI 2.1 ports with 48 Gb/s bandwidth, thanks to the new MediaTek Pentonic 800 chipset. That removes one of the long-standing issues that has plagued the manufacturer's TVs. You can connect several devices at once and use each input's full capabilities, including VRR and ALLM. There's also a simple Game Bar that lets you check 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.

There are, however, two limitations worth knowing. The first is the lack of support for 1440p at 120 Hz. This won't 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 disabling tone mapping on the Bravia 3 II, so the TV continuously processes HDR content even when you would prefer to leave that task to the console. You can most easily notice this during HDR setup. The checkerboard pattern does not disappear at the point corresponding to the TV's actual capabilities. That doesn't mean HDR in games will look bad. You just need to approach the setup a bit differently and, instead of relying on the pattern, manually set the peak brightness to about 450 nits. The issue can be worked around, but you should know about it before you start configuring your console.
