LG OLED G4 vs Sony A95L

LG G4 guarantees an incredibly vibrant HDR effect, placing the television firmly at the top of the rankings. The highest model in the manufacturer's 2024 portfolio, equipped with the second generation of microlens technology (MLA), has achieved a maximum brightness level of 1474 nits in real scenes. The only area where the product of the Korean manufacturer may fall short compared to LCD televisions with Mini LED backlighting is during a full-screen scene featuring a lot of white. If we were to disregard the latter scene, the average result would be even higher. It's also worth mentioning scenes with very fine details, where each one shone at full intensity, which is not as evident in non-OLED televisions. The combination of such brightness and wide coverage of the DCI-P3 color space ensures that HDR materials are more engaging than ever before.

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 in terms of colour reproduction was "Filmmaker". This is the one we used during our tests. Let's check how its characteristics looked before the calibration process. Taking a closer look at the white balance first, we can notice a significant dominance of red and green colour. As a result, the image had a warm yellow tint. This is the kind of characteristic we usually observe in "Cinema", "Filmmaker", or similarly named modes. The effect of such a colour balance was clearly visible in both SDR and HDR content, which, after switching from "Standard" mode, was distinctly yellowed. Now let's move on to two graphs that are responsible for brightness characteristics, and consequently, image contrast. The first one (Gamma), representing materials with a standard colour palette, performed decently. For most of the time, the midtones and bright whites were represented very accurately, however, it noticeably lost the darkest details which blended into a black patch. On the other hand, HDR materials, represented by the EOTF curve graph, exhibited a significant drop in contrast due to a strong boost in brightness. There was also an issue with the colours themselves as seen on the "ColorChecker" graph since they were noticeably undersaturated.

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.

The manufacturer has been implementing extensive support for the calibration process in their LG televisions for many years. Therefore, we used 2- and 20-point grey scale adjustments along with an advanced CMS (Color Management System) and got to work. As you can see, thanks to the procedure carried out, each of the parameters has significantly improved. The use of tools has resulted in extremely beneficial effects, which include: studio colour reproduction, recovery of details in dark areas of the image, appropriate brightness characteristics, and proper colour saturation. Thus, we have maximised our approach to the reference image, or the one that the film director saw on the preview monitor. It is worth noting that the LG G4 televisions are the only ones that allow for even deeper intervention in image quality due to the capability to calibrate with 3D LUT matrices. However, this solution is recommended only for post-production or graphic studios.

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.

The tested television did not perform well with content rich in tonal transitions, resulting in a strong posterisation effect. However, there is a partial remedy for this ailment. The manufacturer has equipped the LG G4 with a smoothing system called "Gentle Gradation," which we can apply at three levels: Low, Medium, and High. Each of these options guarantees quite high smoothing effectiveness on bright colours, though low on darker ones. We recommend primarily using the first one due to the fact that the other two interfere with directorial intentions, removing film grain.

When watching lower-quality content, the efficiency of the television during upscaling is extremely important. The image from the tested television is sharp and clear. However, attention should be paid to the jagged edges of fine details and minor issues around characters, such as the creation of a halo effect, which occurs due to the sharpening imposed by the LG G4 even when the slider is set to the lowest value, which is 0. It is worth noting that this is a change in relation to the LG G3, which did not impose such strong image sharpening, even when the appropriate slider was set to position 0.

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 that we can set on the LG G4 is 144 Hz. Naturally, this is only possible by connecting the LG G4 to a very powerful PC. Otherwise, we will be operating at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with high motion dynamics. For those who require high fluidity of 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 from 0 to 10, with each increment affecting the degree of smoothing, so everyone can find their sweet spot.

The LG OLED G4 panel features an average response time of 0.78 ms (which directly results from our measurements), allowing for an incredibly clear image, unattainable by LCD televisions, which have response times of even several milliseconds. This is clearly visible in the "UFO Test" images, showing the absence of any trailing blur behind the object. Furthermore, the LG OLED G4 test showed that the television offers the ability to precisely adjust motion smoothing functionality, allowing users to choose the ideal level of image interpolation. We particularly appreciated this during fast-paced action in video games, where the LG G4 performed exceptionally well, minimising any blurriness. Thanks to OLED technology, this model eliminates so-called ghosting, ensuring that the image remains sharp even in the most dynamic sports or movie scenes.

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.

The LG G4 television supports all features that make up the HDMI 2.1 standard. During testing, each feature activated without any issues, which allows us to consider the television as designed for gaming. Its performance will certainly be appreciated by both console users and those connecting the LG G4 to a computer. It’s also worth mentioning the proper implementation of the HGIG (HDR Gaming Interest Group) mode, which ensures that games mastered to brightness levels beyond the maximum luminance of the LG G4 will correctly map tones, keeping the game image true to the original.

A nice touch is the presence of a special GameBar that we can bring up at any moment to check game parameters, but most importantly, to change them quickly. More importantly, turning on VRR technology does not degrade contrast, which is often a problem in televisions with local dimming or Mini LED backlighting. Of course, this is thanks to the OLED panel itself, characterised by pixel self-emissiveness. As a journalistic note, we will only mention a slight grey flicker, which, however, is somewhat normal when VRR is enabled.

In summary, the LG G4, like practically all OLED televisions, is an ideal product for all kinds of gaming and online competitions. With full HDMI 2.1 ports with a complete bandwidth of 48 Gbit, features such as VRR, ALLM, G-Sync, FreeSync, or HDR Dolby Vision gameplay will bring a lot of joy.

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.
