LG OLED C4 vs SONY BRAVIA 3

The results of HDR materials are definitely among the better ones. Practically every film significantly exceeds the 700 nits barrier, allowing for a very realistic image. Of course, none of them surpasses the magical thousand, yet the combination of such results and unlimited contrast and black effectively boosts the outcome optically. The last of the scenes, featuring a full-screen burst of sunlight, is actually less bright than the others, although it still represents a commendable level. It is also worth mentioning the excellent coverage of the DCI-P3 colour palette, which will allow for achieving extremely vivid colours.

Bravia 3 does not hide the fact that it belongs to the group of televisions that are rather modest in terms of brightness. Our measurements showed around 370 nits, which is a value teetering on the edge of where one can still speak of any HDR effect. For some, this is an acceptable level, while for others it is rather typical for SDR content, where spectacular highlights or vivid contrasts are not expected. The impression is that this is not a television for those focused on the highest image quality in demanding cinematic content. However, this does not mean that we cannot find any advantages here. Compared to its predecessor, the X75WL, Bravia 3 has gained an additional PFS filter, which works similarly to solutions known from QLED technology. Thanks to this, the DCI-P3 colour palette has been significantly widened and reaches over 91 percent, which in practice results in more saturated colours and a more pleasing image texture. As a result, even everyday content looks somewhat livelier, and films and series can surprise with vibrant visuals, despite limitations in brightness itself.

The best factory mode implemented in the tested television was "Filmmaker". It was this mode that we used during all tests. This mode proved to be quite good in terms of colour reproduction; however, other shortcomings effectively detracted from the enjoyment of viewing. Starting with the most basic aspect, the white balance, it was easy to notice that it was marked by a dominance of red, which overall changed the characteristics of the image. We could thus see a strong yellowing of the whites and a shift of all colours towards warmer shades. The gamma, which is a curve just as important, if not more so, was quite significantly lowered, resulting in a considerable drop in contrast, except at the beginning of the graph, where the television insidiously lost details. That’s all regarding SDR materials. Taking a closer look at films with a wide dynamic range, we can observe exactly the same phenomenon of yellowing of the white balance as in films with a standard colour palette. The EOTF curve, which replaces our gamma curve, is practically perfect and cannot be faulted.

Sony Bravia 3 was primarily tested in film mode, which immediately proved to be the best choice among the factory settings. It is not a perfect picture, but compared to the eco mode that the television offers right out of the box, the difference is clear and positive. In film mode, one can notice a certain problem: the image appears too warm, which results from a lack of blue colour in the white balance. Despite this, in SDR content, the final effect can still be considered quite decent and satisfactory for everyday viewing. Much more serious errors occur in HDR materials. The Color Checker analysis showed considerable deviations, and poor brightness management, combined with limited colour gamut coverage, further exposes the shortcomings of the image in this mode. All of this makes HDR on the Bravia 3 appear unconvincing and can spoil the impression left by the quite decent SDR content setting. Fortunately, this is not an insurmountable situation. Various errors can be somewhat mitigated, and some can even be fully corrected through professional calibration. Therefore, we decided to check how the television would perform after such adjustments.

As we mentioned earlier, LG televisions are equipped with advanced tools for carrying out the calibration process. We therefore used them to model the image in the way that the director intended. And without modesty, we must admit that we achieved this phenomenally. Both SDR and HDR materials present a level that clearly indicates that this is how a film should look. It is worth looking at the colour errors on the "ColorChecker" palette here, where practically none of them exceeds "1", apart from two samples.

The calibration allowed us to extract significantly more from the Bravia 3 than we could have expected at the beginning. Firstly, it managed to compensate for the deficiency of blue, which had previously caused a noticeable warming of the image. After a slight adjustment to the white balance, most of the errors in the Color Checker measurements for SDR content virtually disappeared. The white tones became more natural, and the brightness management in gamma stabilised to an almost ideal level, not exceeding the threshold of human perception. Thus, it can be confidently stated that in SDR content, after a few adjustments to the settings, the Bravia 3 performs remarkably well. Significantly worse, although still definitely better than before calibration, are HDR contents. The white balance was brought into order, however, the limitations of the IPS panel are insurmountable. The lack of local dimming means that even the smallest elements can be overexposed, which immediately stands out. Colour-wise, the effect is also improved, though far from perfect – many errors still exceed the threshold of four or even five delta E units, meaning they remain visible to the human eye. It was already clear earlier that the Bravia 3 is not a television designed to impress with HDR quality. Nevertheless, it is gratifying that in SDR content, after calibration, the image can look truly excellent, and in this category, the television pleasantly surprised us.

Once again, we will take a look at the function responsible for smooth gradation, but we will also address the one that aims to improve the quality of lower-quality materials. The default smoothing of tonal transitions, as we have seen, was not the worst, but it can still be improved. The function has a slider, which allows us to adjust its strength. We recommend using the first one, as it yields very good results and does not blur important details.

Image scaling in 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. Admittedly, there are jagged edges on the trees, but this is not a major issue compared to other manufacturers.

Bravia 3 brings something more to the Sony TV family than just a shared name. It stands out primarily for its ability to enhance the quality of weaker materials thanks to the processor used. Of course, we won’t find the advanced XR chip known from more expensive models here, but even so, it must be admitted that the image in lower resolutions looked surprisingly good. The scaling worked effectively, and most parts of the screen were free from the typical excessive edge tearing found in budget constructions.

Attention should also be paid to the function that improves the smoothness of tonal transitions. In the high setting, it works really well, effectively masking gradation imperfections without significant detail loss. It does happen, however, that the algorithm overly smooths elements that should remain sharp – for example, faces – but overall, the effect is beneficial. The best results were achieved precisely at the highest setting, and this option could be recommended to those watching lower quality content.

The maximum refresh rate that we can set on the LG G4 is 144 Hz. Naturally, this is only possible when connecting the television to a very powerful PC. In other cases, we will be operating at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sport or content with a lot of motion dynamics. For those requiring high fluidity of the image, the manufacturer has implemented a multi-step 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 within a range from 0 to 10, with each degree affecting the degree of smoothing, allowing everyone to find their golden mean.

The LG OLED C4 panel features an average response time of less than 1 ms (which directly results from our measurements), allowing for an incredibly clear image that is unattainable for LCD televisions, whose response times can be as high as several milliseconds. This is clearly visible in the pictures from the "UFO Test," showing no trailing blur behind the object.

The fluidity of motion has never been a strong point of televisions equipped with 60 Hz panels, and the Bravia 3 is no exception. Nevertheless, Sony has added something that may appeal to those more sensitive to the way images are displayed. We are talking about the proprietary motion smoother, Motion Flow, which offers users a considerable range of adjustment options. Thanks to it, one can make the image smoother, even theatrical, or stick to a more cinematic style with the characteristic judder that many simply associate with the filmic atmosphere. These functions work with content at lower frame rates, such as films and series recorded at 24 or 30 frames per second, which are the materials we encounter on a daily basis. It is here that the motion smoother proves to be one of the most important features in everyday use of the television, and this is where the Bravia 3 performs quite well.

We can already say that LG C4, like practically every OLED television from the manufacturer, is exceptionally good in terms of compatibility with consoles and PCs. Thanks to the implementation of four full bandwidth HDMI 2.1 ports at 48 Gbps, the manufacturer has included all features that enhance the gaming experience, among which we find simultaneous support for FreeSync and G-Sync technology. With such a tandem, gamers with a graphics card from AMD or Nvidia can confidently opt for C4. However, what should delight the players requiring the highest possible quality the most is the simultaneous implementation of HDR Dolby Vision and HGIG mode. The first is particularly important as it works with extremely low input lag in all settings.

A standard in the Korean manufacturer's televisions is also the implementation of GameBar, allowing for quick adjustments of settings "on the fly" without the need to exit the game. It also enables image adjustments for visually impaired individuals, which is a very nice touch. Another important piece of information is that when VRR technology is enabled, we will not experience a drop in contrast. This is, of course, due to the panel's design and the absence of conventional backlighting. However, it is 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 of the manufacturer's OLEDs equipped with high refresh rate panels and HDMI 2.1 ports, creates a harmonious whole with consoles. In practice, it is a complete television, and if we expect the highest possible performance in gaming, C4 will be an ideal choice.

Bravia 3 is not equipment for e-sports enthusiasts or fans of night marathons with a controller in hand. The lack of 120 Hz refresh rate and HDMI 2.1 ports closes the topic before it even has a chance to develop. This is a television for casual gamers who will play FIFA or racing games after work, not for someone who measures every frame in a spreadsheet. Nevertheless, Sony has added a few nice extras to ensure it’s not too sparse. ALLM works as it should, automatically switching the television to game mode (low latency). There’s even a simple Game Bar, which is clear. However, the biggest novelty here is the PlayStation Portal app. Thanks to it, you can launch PS5 games wirelessly and view them immediately on the television screen. It sounds great, but just a few minutes is enough to feel significant lag. In our opinion, it’s more of a showcase of capabilities than something that can be used every day. If someone really wants to play, it’s better to connect the console via HDMI cable and forget about wireless issues.
