LG OLED C4 vs Sony A95L

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.

Sony A95L offers an incredible HDR effect, achieving an impressive brightness level of 1500 nits in scenes such as those from Life of Pi or Sicario 2. These results are truly remarkable – the bright elements in these films practically come to life on the screen, providing the viewer with immersive visual experiences. The only thing that can be noticed is minor issues with maintaining brightness in a scene from The Meg, where the entire scene is flooded with light. However, this is a natural effect associated with OLED technology. The wide coverage of the BT.2020 colour palette at 89% also deserves high praise, placing A95L Sony among the top televisions in terms of colour reproduction. All this is made possible by the QD-OLED panel from Samsung Displays.

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.

The best factory mode for colour reproduction in the Sony A95L is IMAX Enhanced. This mode appears to be well calibrated at first glance, but upon closer examination, several areas requiring improvement can be identified. Firstly, the white balance for both SDR content and 4K HDR is affected by an excess of blue and red, leading to a subtle pinkish hue, particularly noticeable on neutral tones. As a result, skin tones are distorted, impacting the realism of the displayed image. This is clearly visible in the comparison image below. Additionally, the Colour Checker test confirms the presence of these errors – colour samples often deviate from their reference values, indicating some inconsistencies in the factory colour reproduction of the A95L Sony. Maximum deltaE error values reach up to 5.8, which is a clear indicator that colours are not always reproduced as precisely as they should be.

Regarding brightness characteristics, gamma for HD/SDR content is generally quite accurate, maintaining an appropriate balance between brightness and contrast. Unfortunately, a significant jump is visible at the end of the graph, leading to a strong brightening of the image when the screen is entirely flooded with white. This can make scenes with a very bright background, such as snowy landscapes or bright daylight, appear too harsh and lose detail. For HDR content, the EOTF curve, which controls luminance, is slightly boosted compared to reference values. This, in turn, causes the image to appear somewhat brighter than it should, which can affect the viewing of more subtle details in the darker parts of the frame.

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.

Sony A95L offers excellent tools for professional screen calibration, which allows users to unlock the maximum potential of the IMAX Enhanced mode. We utilised these tools to achieve a picture quality that will satisfy even the most demanding viewers. After calibration, the white balance for both 4K HDR and SDR content looks simply superb – almost perfect. The Colour Checker test confirmed that deltaE errors do not exceed the value of "2", which means that colour reproduction is incredibly accurate, and any deviations are practically unnoticeable to the human eye.

Calibration also brought significant improvements in terms of brightness – gamma is now perfectly balanced, eliminating the previous issue of excessive lightening in scenes with very bright backgrounds. As a result, even the most vibrant moments, such as snowy landscapes or intense daytime scenes, appear natural, without any risk of overexposure. The EOTF curve, responsible for controlling luminance in HDR content, has also been improved – it now reaches reference levels, both in synthetic tests and during practical movie watching.

As a result of the calibration, A95L Sony offers outstanding experiences, whether you are watching content from regular television or your favourite films. Every detail is reproduced exactly as the creators intended – without unnecessary brightening, with perfectly rendered colours and appropriate depth. This demonstrates that this television, after professional tuning, is capable of competing with the best screens on the market, delivering a picture that truly delights.

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.

The tonal transition smoothing feature in Sony A95L works really well and is worth noting. We recommend setting it to "Medium" because at this level, you achieve the perfect compromise – no artifacts appear, and the image looks incredibly natural and pleasing to the eye. As a result, the transitions between different shades are smooth while maintaining the detail of the scenes, which further enhances the viewing comfort.

When it comes to upscaling, you can see the full power of the XR processor here. Sony A95L handled our test material featuring a model exceptionally well – the image is remarkably clear, there are no excessive jagged edges, and details in the background are perfectly preserved. The XR processor effectively improves low resolution, delivering very good results that allow you to enjoy materials in almost high quality, even if their source is not ideal.

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.

Sony A95L is a television that should satisfy both gamers and cinema lovers. When it comes to watching films, this model is equipped with the Motionflow feature, which allows you to precisely adjust whether you want the image to be more "cinematic," like in traditional cinema, or exceptionally smooth, like in cinema-style TVs. The "Smoothness" slider lets you regulate the level of fluidity – from subtle changes to a more noticeable effect, while the "Clarity" slider is responsible for reducing flicker and artifacts, helping to achieve a more natural and clear motion. As for gaming and watching sports, the A95L Sony television offers a refresh rate of 120 Hz, making every dynamic action look incredibly smooth. Gamers will appreciate the lack of blur, while sports fans will see every movement in full clarity. Overall, the television performs excellently – both with fast-paced games and emotionally charged film sequences.

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.

Sony A95L is a television that will truly satisfy gamers, thanks to several key features that set it apart from the competition. To start with, the 120 Hz refresh rate – this is something everyone who loves fast action games, racing, or dynamic shooters will appreciate. As a result, the image is exceptionally smooth, and the gameplay is more satisfying, without annoying stuttering. The A95L Sony also has an ALLM (Auto Low Latency Mode) feature, which automatically engages low latency mode when we turn on the console. What does this mean? Above all, faster response on the screen, which in games where every second matters is simply invaluable. Additionally, there’s VRR (Variable Refresh Rate), which adjusts the image refresh rate to the number of frames generated by the console. The effect? No tearing of the image, and everything looks smooth and cohesive – even with variable FPS.

It is worth mentioning the support for Dolby Vision with low input lag in games – something we don’t often encounter in televisions, and here we have it onboard. Thanks to this, the image in games that support HDR is incredibly vibrant, with rich colours and excellent contrast. Both the brightest and darkest details are visible, making everything look as the game creators intended. And then there's the "Game Bar" – a small but very practical feature. With it, we have all the most important gaming-related settings at our fingertips, such as VRR or latency information. There’s no need to interrupt gameplay to adjust parameters – everything is right at hand.

However, it should be remembered that the A95L offers only two full-bandwidth HDMI 2.1 ports, one of which is designated for eARC. This may pose a limitation if we plan to connect multiple devices – for instance, a next-gen console and a soundbar simultaneously. In such a case, the eARC occupying one of those ports can be somewhat problematic, blocking the possibility of connecting a second console.
