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, 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.

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

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 best factory mode for colour reproduction on the Sony A95L is IMAX Enhanced. This mode seems well-calibrated at first glance, but upon closer analysis, several areas for improvement become apparent. Firstly, the white balance for both SDR and 4K HDR content is marred by an excess of blue and red hues, leading to a subtle pink tint, particularly noticeable on neutral tones. As a result, skin tones are skewed, affecting the realism of the displayed image. This is clearly visible in the comparison photo below. Additionally, the Colour Checker test confirms the presence of these errors – the colour samples often deviate from their reference values, indicating some inaccuracies in the factory colour reproduction of the A95L Sony. The maximum deltaE error values reach up to 5.8, which is a clear indicator that colours are not always reproduced as accurately as they should be.

Regarding brightness characteristics, the gamma for HD/SDR content is generally quite good, 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 fully flooded with white. This can make scenes with very bright backgrounds, such as snowy landscapes or intense daylight, appear too glaring and lose detail. For HDR content, the EOTF curve, which controls luminance, is slightly elevated compared to reference values. This, in turn, causes the image to be somewhat brighter than it should be, which can affect the perception of more subtle details in the darker areas of the frame.

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.

Sony A95L offers excellent tools for professional screen calibration, allowing you to maximise the potential of the IMAX Enhanced mode. We used them to achieve an image quality that satisfies even the most demanding viewers. After calibration, the white balance for both 4K HDR and SDR content looks simply fantastic – nearly perfect. The Colour Checker test confirmed that deltaE errors do not exceed a value of "2", which means that colour reproduction is extremely accurate, and any deviations are practically imperceptible to the human eye.

The calibration also brought a significant improvement in brightness – gamma is now perfectly balanced, eliminating the previous problem of excessive brightening in scenes with very bright backgrounds. Thanks to this, even the brightest moments, such as snowy landscapes or intense daytime scenes, appear natural, without the risk of blown-out highlights. The EOTF curve, responsible for controlling luminance in HDR content, has also been improved – it now reaches reference levels in both synthetic tests and practical movie watching.

As a result of the calibration, A95L Sony provides an excellent experience, whether you are watching regular TV content or your favourite films. Every detail is reproduced exactly as the creators intended – without unnecessary brightenings, with perfectly rendered colours and appropriate depth. This shows that this television, after professional tuning, can compete with the best screens on the market, offering an image that truly impresses.

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.

The tonal transition smoothing function in Sony A95L works really well and is worth noting. We recommend setting it to "Medium" level, as this value achieves an ideal compromise – no artifacts appear, and the image looks incredibly natural and pleasing to the eye. This ensures that transitions between different shades are smooth while maintaining scene detail, which further enhances 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 the background details are perfectly preserved. The XR processor effectively improves low resolution, providing very good results that allow you to enjoy content in nearly high quality, even if its source is not perfect.

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

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.

Sony A95L is a television that will truly satisfy gamers, thanks to several key features that set it apart from the competition. To begin with, the 120 Hz refresh rate – this is something that anyone who loves fast-paced action games, racing, or dynamic shooters will appreciate. This makes the image exceptionally smooth, and gameplay more satisfying, without annoying stutters. The A95L Sony also has an ALLM (Auto Low Latency Mode) feature, which automatically activates low-latency mode when we start up a console. What does this mean? Primarily, faster reactions on screen, which in games where every second counts, is simply invaluable. Added to that is VRR (Variable Refresh Rate), which ensures that the image refresh rate adapts to the number of frames generated by the console. The effect? No tearing of the image, and everything looks smooth and cohesive – even with varying FPS.

It's worth mentioning the support for Dolby Vision with low input lag in games – something we don't often see in televisions, but here it is included. As a result, the image in HDR-compatible games is incredibly vibrant, with vivid colors and excellent contrast. Both the brightest and darkest details are visible, making everything look just as the game developers intended. And there's also the "Game Bar" – a small but very practical convenience. It gives us all the essential gaming-related settings at our fingertips, such as VRR and lag information. There's no need to interrupt gameplay to adjust settings – everything is at hand.

However, it's important to note that the A95L offers only two full-bandwidth HDMI 2.1 ports, one of which is allocated for eARC. This could be somewhat limiting if we plan to connect multiple devices – for example, a next-gen console and a soundbar simultaneously. In such cases, eARC occupying one of those ports may be a bit problematic, blocking the option to connect a second console.
