LG OLED G4 vs Sony A95L

LG G4 guarantees an incredibly vivid HDR effect, placing the television among the very best. The equipment of the highest model in the producer's 2024 portfolio with the second generation of micro-lens technology (MLA) has achieved a maximum brightness level of 1474 nits in real scenes. The only area where the product from the Korean manufacturer may lag behind LCD televisions with Mini LED backlighting is during the full-screen scenes featuring a lot of white. If we disregard the latter type of scene, the average result would be even higher. It is also worth mentioning scenes with very fine details, where each one shines at full intensity, which is not as evident in non-OLED televisions. The combination of such brightness and wide coverage of the DCI-P3 palette makes HDR materials 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 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 in terms of colour reproduction was "Filmmaker". This was the one we used during our tests. Let's check how its characteristics looked before the calibration process. Looking closely at the white balance first, we can notice a significant dominance of red and green. As a result, the image had a warm yellowish hue. Such characteristics are typically observed in "Cinema", "Filmmaker" or similarly named modes. The effect of this colour balance was clearly visible in both SDR and HDR content, which after switching from "Standard" mode appeared distinctly yellow. Now, let's move on to two graphs that are responsible for the brightness characteristics and consequently the contrast of the image. The first one (Gamma), representing materials with a standard colour palette, performed decently. For most of the time, midtones and bright whites were reproduced very accurately; however, it noticeably lost the darkest details, which merged into a black blob. Conversely, HDR materials, represented by the EOTF curve graph, exhibited a significant drop in contrast due to a strong boost in brightness. The colours themselves also posed a problem, as can be seen on the "ColorChecker" graph, since they were noticeably under-saturated.

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.

The manufacturer has implemented extensive support for the calibration process in its LG televisions for many years. We therefore used 2- and 20-point greyscale adjustments, as well as an advanced CMS (Colour Management System), and got to work. As you can see, thanks to the procedure carried out, each parameter has significantly improved. The use of tools allowed for the achievement of extremely beneficial effects, which include: studio colour reproduction, recovery of details in dark areas of the image, appropriate brightness characteristics, and suitable colour saturation. This brings us as close as possible to the reference image, which is what the film director saw on the preview monitor. It is worth noting that the LG G4 televisions alone allow for even deeper intervention in image quality thanks to the ability to calibrate with 3D LUTs. However, this is a solution recommended only for post-production or graphic studios.

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.

The tested television did not perform particularly well with materials rich in tonal transitions, as a result of which we could observe a strong posterisation effect. However, there is a partial remedy for this issue. 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 a high effectiveness of smoothing on light colours, although it is low on darker ones. We recommend primarily using the first one, as the other two interfere with the director's intentions by removing film grain.

When watching lower-quality materials, the efficiency of the television during upscaling is extremely important. The image from the tested television is sharp and clear. However, one should pay attention to the jagged edges of fine details and minor issues around characters, such as the creation of halo effects, which occurs due to the sharpening imposed by LG G4 even when the lowest value on the slider, that is 0, is set. It is worth noting that this represents a certain change compared 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 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 the LG G4 is connected 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 high motion dynamics. For those requiring high image fluidity, the manufacturer has implemented a multi-level motion smoother called "TrueMotion". This 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 level affecting the degree of smoothness, allowing everyone to find their golden mean.

The LG OLED G4 panel features an average response time of 0.78 ms (as directly derived from our measurements), enabling an incredibly clear image, unattainable by LCD televisions, which can have response times of several milliseconds. This is perfectly illustrated by the images from the "UFO Test", which show no trailing blur behind the object. Moreover, the LG OLED G4 test revealed that the television offers the ability to precisely adjust the motion smoothing function, allowing users to select the ideal level of image interpolation. We particularly appreciated this during fast-paced actions in video games, where the LG G4 performed exceptionally well, minimising any blurring. Thanks to OLED technology, this model eliminates so-called ghosting, ensuring that the image remains sharp even in the most dynamic sporting or cinematic scenes.

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.

The LG G4 television supports all the features that make up the HDMI 2.1 standard. During testing, each of them activated without the slightest problem, which allows us to consider the television as designed for gaming. Their functionality will surely be appreciated by both console users and those connecting the LG G4 to a computer. It is also worth mentioning the correct implementation of the HGIG (HDR Gaming Interest Group) mode, which ensures that games mastered to brightness levels exceeding the maximum luminance of the LG G4 will correctly map tones, and the game's visuals will remain true to the original.

A nice touch is the existence of a special GameBar, which we can call up at any moment to check game parameters, but most importantly, to change them quickly. More importantly, enabling VRR technology does not degrade contrast, which is very common in televisions that feature local dimming or Mini LED backlighting. Of course, this is thanks to the OLED panel itself, characterised by pixel self-emission. As a matter of editorial obligation, we will only mention a slight grey flicker, which is somewhat normal after enabling VRR.

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

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.
