Sony Bravia 8 (XR80) vs LG OLED C4

Sony Bravia 8 performs reasonably well in terms of HDR brightness. A maximum brightness level of 880 nits is satisfactory and allows for well-rendered lighting effects in most scenes. In the tested segments of the films Life of Pi and Sicario 2, the TV presents itself quite well, offering vibrant and detailed images that fully capture the atmosphere of these productions.

However, a greater challenge arises in a scene from the film The Meg, where the screen is entirely very bright. In such situations, the limitations of OLED technology become apparent, as the TV loses brightness, dropping to around 450 nits. Such a drop is less satisfying, especially when the entire scene requires intense lighting. Despite these limitations, Sony Bravia 8 remains a competitive model, offering excellent coverage of the DCI-P3 colour gamut and 74% coverage of the BT.2020 standard. This results in rich colours and precise details, significantly enhancing the quality of HDR content viewing and making for a pleasurable experience.

The results of HDR materials are definitely among the better ones. Practically every film significantly exceeds the 700 nits barrier, which allows for a very realistic image. Of course, none of them surpasses the magical thousand, however, the combination of such results along with unlimited contrast and black effectively boosts the visual outcome. The last of the scenes, featuring a fullscreen sun burst, is indeed less bright than the others, although it still represents a respectable level. It's also worth mentioning the excellent coverage of the DCI-P3 colour palette, which will enable the achievement of exceptionally vivid colours.

The best factory mode available on the Sony Bravia 8 television is IMAX Enhanced, which provides the most cinematic experience, although it is not set up perfectly. The TV tries to replicate cinema settings as faithfully as possible, however, certain shortcomings are noticeable. Starting with white balance, both for SDR materials and 4K, there is a clear dominance of blue. This makes the picture appear too cold, taking away its naturalness. Tests using Colour Checker show that colours shift towards cooler shades, which may lead to less accurate colour reproduction and makes the image less realistic.

As for brightness and contrast characteristics, gamma shows a significant drop at the end of the graph. This means that dark details may be too dim, while bright elements are too bright, causing them to lose subtlety and become less visible. As can be seen in the sky - in the comparison photo. Meanwhile, the EOTF curve is significantly above the reference value, causing the bright elements of the image to be too intense. As a result, users may perceive the image as unnatural, and bright areas may lose detail, negatively impacting the overall viewing quality.

The best factory mode implemented in the tested television was "Filmmaker". That was the one we used during all tests. This mode, in terms of colour reproduction, turned out to be quite decent, although other flaws effectively detracted from the enjoyment of the viewing experience. Starting with the most basic one, which is white balance, it was easy to notice that this was marked by a dominance of red, which completely altered the characteristics of the picture. We could see a strong yellowing of the whites and a shift of all colours to warmer tones. The gamma, which is a graph as equally important, if not more so, was quite severely reduced, resulting in a significant drop in contrast, except for the start of the graph, where the television insidiously lost details. That’s all regarding SDR materials. Looking closely at films with a wide dynamic range, we can observe exactly the same phenomenon of white balance yellowing as in films with a standard colour palette. The EOTF curve, which replaces the gamma chart for us, is practically perfect and cannot be faulted.

The calibration process of the Sony Bravia 8 television has brought significant improvements in image quality. The white balance has been distinctly enhanced, both for SDR content and 4K HDR, with minimal errors in the middle section of the graph. Gamma proved to be one of the biggest beneficiaries of the calibration – it has been completely stripped of previous drops, which significantly affected brightness stability and better detail reproduction in dark parts of the image. The EOTF curve has also been levelled out, making bright elements of the image appear more natural, and the overall tonal dynamics are now more balanced.

However, the most attention should be paid to colour reproduction, where despite the calibration, there are still some issues. Sony has omitted the use of a CMS system in this model, which allows for very precise control over colours. Consequently, the Colour Checker test for 4K materials still shows significant errors in colour samples. Despite these difficulties, we recommend carrying out the calibration, as the effects are noticeable and significantly enhance image quality, especially in terms of brightness and contrast.

As we mentioned earlier, LG televisions are equipped with advanced tools for carrying out the calibration process. We used them to model the picture in line with what the director envisioned. And without modesty, we must admit that we achieved this phenomenally. Both SDR and HDR materials present a level that clearly indicates this is how a film should look. It's worth taking a look at the colour errors on the "ColorChecker" palette, where practically none of them exceed "1", except for two samples.

The fluidity of tonal transitions in low-quality materials on the ChooseTV 8 is lacking. Unfortunately, the gentle gradation feature (which was available in previous models) is missing, which is a significant downside. The digital noise reduction function can improve tonal transitions quite well, but it also tends to remove some details, such as clouds in scenes from the film The Martian, which may not appeal to everyone. When it comes to digital processing, the Sony XR80 TV performs quite well. The model in the test scenes is displayed without noticeable errors, and the branches in the background are not overly jagged. This shows that ChooseTV 8 is capable of processing complex image details at low resolution well.

Once again, we will take a look at the feature responsible for gentle gradation, but we will also address the one that aims to enhance the quality of lower-quality materials. The default smoothing of tonal transitions, as we could see, was not the worst, but it can be improved further. The function has a slider that allows us to adjust its intensity. We recommend using the former, as it produces very good results and does not blur important details.

Image scaling on LG C4 is quite good, however, it cannot be said to be without flaws. The image is slightly sharper by default, although not in a very noticeable way. While jagged edges of trees can be seen, it is not a major issue when compared to other manufacturers.

Sony Bravia 8 offers a maximum refresh rate of 120 Hz, which lays the groundwork for smooth viewing of dynamic content such as sports and games. As a result, movements are sharp and fluid. For more demanding users, the Sony XR80 television is equipped with an advanced motion smoothing system, which is divided into three segments: Smoothness (Film), Smoothness (Camera), and Clarity. The first two are responsible for adjusting the level of blur and smoothing of the image. The third option, concerning clarity, will be described in more detail below. Each of the parameters can be tailored to personal preferences, allowing users to find the optimal setting suited to their individual needs.

The maximum refresh rate we can set on the LG G4 is 144 Hz. Naturally, this is only possible when connecting the TV 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 a lot of motion dynamics. For those who require high fluidity of the 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 of 0 to 10, with each degree affecting the level of smoothing, allowing everyone to find their sweet spot.

The panel of the LG OLED C4 features an average response time of less than 1 ms (which directly results from our measurements), enabling the achievement of an extremely clear image, unattainable for LCD TVs, which can have response times of up to several milliseconds. This is clearly evident in the images from the "UFO Test," which show no trailing blur behind the object.

Sony Bravia 8 has significantly improved its compatibility with consoles compared to earlier models. The TV supports variable refresh rate (VRR), which eliminates screen tearing, and is compatible with graphics cards, ensuring smooth visuals. The auto low latency mode (ALLM) reduces input lag, which is crucial in fast-paced games. Dolby Vision with low latency additionally provides impressive HDR effects that look fantastic during gameplay.

The Sony XR80 TV also features a Game Bar, which allows quick access to settings and monitoring parameters while gaming. An interesting option is the ability to enable a virtual crosshair on the screen, which can provide a slight advantage in shooter games.

A downside is the lack of support for 1440p@120hz resolution, which could make gaming easier for users with less powerful graphics cards. Additionally, the Sony XR80 only has two HDMI 2.1 ports, one of which is typically used to connect an audio system via eARC, limiting the number of available ports for connecting next-gen consoles.

We can now say that LG C4, like practically every OLED television from the manufacturer, is exceptionally good in terms of cooperation with consoles and PCs. Thanks to the implementation of four full-bandwidth HDMI 2.1 ports at 48 Gbps, the manufacturer has embedded all the features that enhance gaming comfort, including simultaneous support for FreeSync and G-Sync technologies. With such a tandem, players with graphics cards from AMD or nVidia can safely choose C4. However, what should please gamers demanding the highest possible quality the most is the simultaneous implementation of HDR Dolby Vision and HGIG mode. The former is particularly important as it operates with extremely low input lag in all settings.

A standard feature in televisions from the Korean manufacturer is also the implementation of GameBar, allowing for quick adjustments of settings "on the fly," without the need to exit the game. It also allows for image adjustments for people with visual impairments, which is an incredibly nice touch. Another important piece of information is that when VRR technology is enabled, we won’t experience a drop in contrast. This is, of course, due to the design of the panel and the absence of conventional backlighting. It is, however, normal for shades of grey to flicker slightly, although this is a characteristic feature of this function regardless of the manufacturer and television.

In summary: LG C4, just like all the manufacturer's OLEDs equipped with high-refresh-rate panels and HDMI 2.1 connections, creates a harmonious whole with consoles. In practice, it is a complete television, and if we expect the highest possible efficiency in gaming, C4 will be an ideal choice.
