LG UT8100 (IPS) vs SONY BRAVIA 3 II (XR35M2)

The LG UT8100 television unfortunately does not meet expectations in the HDR effect category. A peak brightness of only 300 nits on the luminance chart is well below the required value to fully enjoy HDR effects. In practice, the image resembles SDR quality more than true HDR, which is particularly evident in demanding high-contrast scenes. The coverage of the DCI-P3 colour palette is only 82%, which further limits the ability to present vibrant and rich colours. Instead of impressive visual experiences, we receive a muted and washed-out image. For those looking for a television to fully utilise HDR content, the LG UT8100 model turns out to be quite disappointing.

The Bravia 3 II isn't exactly a TV that tries to impress with brightness. In our measurements it reached around 450 nits, so it's well short of the brightest models on the market. That doesn't mean HDR is just a paper feature here. Compared with standard SDR material, the brightest parts of the image can already punch through noticeably, and highlights, light sources and 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 the screen contains lots of bright elements. Then the Bravia 3 II can give a taste 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 bold, spectacular HDR we’re left with a merely competent picture.

Colours

The Bravia 3 II uses a QLED panel, although technically it doesn't employ a traditional quantum-dot layer. Instead Sony has used a PFS phosphor-based solution, which performs a very similar role: it allows for more saturated reds and greens, and thus reproduces a much wider colour gamut. In our measurements coverage of the DCI-P3 gamut was about 94%, and of the very wide BT.2020 around 74.4%. Those are good results for this class of hardware, which means the Bravia 3 II has no problem showing suitably saturated colours in HDR material. Colours don't look washed out, and the more intense hues can look really attractive.

The Filmmaker Mode on LG UT8100, while theoretically the best for watching movies, has significant issues. The biggest problem is the white balance – drops in blue cause a noticeable yellowing of the image, visible in both HD and 4K content. These issues are confirmed by measurement results in the Colour Checker test, which indicate significant deviations in colour reproduction.

In terms of brightness characteristics, both HD and 4K content exhibit a large tonal boost. The gamma curve in both cases remains well below the reference value of 2.4, which leads to excessive brightening of darker elements of the image. A similar problem is evident in the EOTF curve – in the case of 4K content, the TV struggles to manage brightness correctly, resulting in issues with screen brightness. This means the factory settings of this model require significant adjustment to achieve better picture quality.

In Professional mode the Bravia 3 II 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. The white balance isn't perfect either; as brightness increases a bit of blue and red drops away, so whites can sometimes appear a touch warmer with a faint greenish tint. These aren't mistakes that immediately jump out when watching a film. Average error values hover around 3, so the factory setup can be considered quite good. The situation in HDR is similar. Here too there's a slight lack of blue, so the picture is marginally warmer than the reference, but the difference isn't large enough to be distracting during normal viewing.

After calibrating the Filmmaker Mode, the gamma has been aligned to practically perfect, reference values, which has significantly improved the overall tonal characteristics in HD content. 4K HDR content also looks better, although some issues are still visible at the extreme ends of the graph, where the curve deviates from the ideal. The EOTF curve performs worse since the TV struggles to maintain the correct brightness values. As a result, the image in some scenes may be too bright or slightly dim, which stems from the device’s design. Nevertheless, the calibration brought significant improvement, particularly for HD content, where the tonal balance and colour reproduction are now at a much higher level.

After calibration you can get a lot out of SDR material. The white balance was set almost perfectly, gamma practically matches the reference value, and average colour errors fell from around 3 to about 1. That’s already the level at which differences from the reference image are very hard to spot in practice. The Bravia 3 II therefore shows that despite its place in Sony’s range it has quite a bit of potential for precise picture tuning. Improvement is also visible in HDR, although here you can’t avoid all the limitations of the TV itself. Once the colours are evened out 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 gently darkens parts of the image. That isn’t ideal from a reference point of view, but in this particular TV it also has an advantage. With no local dimming and average black levels this behaviour slightly reduces the visibility of the backlight in darker scenes and helps preserve a stronger sense of contrast. You could say Sony is partly masking the limitations of the panel this way, rather than trying at all costs to stick to the reference brightness.

The fluidity of tonal transitions is also correct, although the effect depends on the settings. The update improved the operation of the smooth gradation function, smoothing transitions better than before, but introduced minor issues with detail loss, e.g. on textures.

Image scaling on LG UT8100 performs very well. The image presents itself decently, with no major issues regarding edge aliasing. Details are preserved at a satisfactory level, making materials of lower resolution look really solid on this television. As a result, users can enjoy watching older content without any noticeable defects in quality.

Bravia 3 II is Sony's first TV to use the new MediaTek Pentonic 800 chip, and you can see a few changes in the image processing. Starting with the basics: the upscaling itself is decent. The TV can sensibly upscale lower-resolution material and doesn't have a strong tendency to over‑emphasise jagged edges or other source imperfections. With regular broadcast TV or lower-quality streaming material the picture therefore remains quite attractive.

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 job is basically the same: to smooth out ugly tonal transitions and artifacts caused by heavy compression. Unfortunately, this function performs noticeably worse than before. At the "Large" setting (the only one that had any visible effect) the TV can smooth away too many image elements at once, which causes film grain to disappear and object textures or even skin to start looking unnatural. Worse still, the effect is not particularly stable. When there's more motion in a scene, the function's effect noticeably weakens and at times it looks as if the TV stops intervening in the image altogether. So for everyday viewing we wouldn't recommend using it at a high level. It can help on static shots, but the trade-off is often too much loss of detail.

LG UT8100, equipped with a 60 Hz panel, is particularly suited for those watching movies. The television offers the TruMotion system with a de-judder effect adjustment, which allows users to tailor the smoothness of the picture – from more choppy to exceptionally smooth, resembling a soap opera effect, depending on user preferences.

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. Sony has, however, managed that issue very well here. Fast-moving objects remain sharp, and the characteristic motion trails and blur are reduced to a very low level, if not to zero. It's one of the least motion-blur-prone 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.

LG UT8100 offers basic features for gamers, such as ALLM and Game Bar, which makes it easier to access settings. The TV also supports HGiG, improving picture quality in HDR games. Unfortunately, the lack of support for Dolby Vision and VRR limits the device's capabilities, as does the 60 Hz panel, which excludes support for 120 Hz resolution. This model is more suited for less demanding gaming applications.

The Sony Bravia 3 II is a very good TV for gamers, although not everything has been solved the way we’d like. The biggest change concerns the connectors. 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 problems that has hung over this manufacturer’s TVs for years. You can connect several devices at once and on each input use the device’s full capabilities, including VRR and ALLM. There’s also a simple Game Bar that lets you check the 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. That won’t be an issue 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 doesn’t let you disable tone mapping on the Bravia 3 II, so the TV keeps processing HDR even when you’d prefer to leave that task to the console. It’s easiest to spot during HDR setup—the checkerboard test pattern doesn’t disappear at the point where it should based on the TV’s actual capabilities. That doesn’t mean HDR in games will look bad. You just need to set up a little differently and, rather than relying on the pattern, manually set the peak brightness to about 450 nits. So the issue can be worked around, but you should know about it before you start configuring your console.
