LG 55 B4 vs Sony A95L

The HDR brightness performance of the LG B4 is impressive, even though it doesn't surpass 1000 nits. Its luminance stability is consistently strong across various scenarios, delivering a reliable viewing experience. The only instance where the TV shows slight weakness is in scenes with large areas of bright white, which has long been a challenge for OLED technology. However, perfect contrast, deep blacks, and excellent brightness ensure a fully immersive HDR experience. Furthermore, the TV’s remarkable 99% coverage of the DCI-P3 colour gamut enhances its colour vibrancy, making images appear rich and visually striking. This level of colour accuracy and brightness balance firmly places the LG B4 among the top choices for HDR content.

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 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 related to OLED technology. The wide coverage of the BT.2020 color palette at 89% is also a significant advantage, placing A95L Sony among the top TVs in terms of color reproduction. All of this is made possible by the QD-OLED panel from Samsung Displays.

The best factory preset offered by LG B4 is the "Filmmaker" mode, which we used throughout our testing. Straight out of the box, the TV delivered fairly accurate colour reproduction. However, the most significant issue in both SDR and HDR content was the white balance. In SDR, there was a noticeable red dominance, giving the image a distinct yellow tint, particularly evident in skin tones and whites. In HDR, this red hue persisted, but the lack of blue also introduced a greenish tint in certain scenes. Additionally, we observed some inconsistencies in grayscale and colour accuracy. Despite these shortcomings, the overall picture quality was still solid for most viewing scenarios.

The best factory mode in terms of color reproduction in Sony A95L is IMAX Enhanced. This is a mode that, at first glance, seems to be well calibrated; however, upon closer examination, several areas requiring improvement can be noticed. First and foremost, the white balance for both SDR and 4K HDR content is skewed with excessive blue and red color, leading to a subtle pink tint, particularly noticeable on neutral tones. As a result, skin tones are inaccurate, 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—color samples often deviate from their reference values, indicating some inaccuracies in the factory color reproduction of A95L Sony. The maximum deltaE error values reach up to 5.8, which is a clear indication that colors are not always reproduced as precisely as they should be.

Regarding brightness characteristics, the gamma for HD/SDR content is generally quite correct, maintaining an appropriate balance between brightness and contrast. Unfortunately, there is a significant jump 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 overly vivid and lose detail. In the case of HDR content, the EOTF curve, which is responsible for controlling luminance, is slightly boosted compared to the reference values. This, in turn, causes the image to be somewhat brighter than it should be, which may affect the perception of more subtle details in the darker areas of the frame.

LG B4 has long been known for offering advanced calibration tools, and it remains one of the few manufacturers that allows such in-depth image adjustments. Thanks to these tools, we calibrated the device to an exceptional standard. The result was incredibly low deltaE errors, considered at a reference level. Both SDR and HDR content now display exactly as the filmmaker intended. This level of precision is one of the reasons LG TVs are frequently used as preview monitors in graphic design and post-production studios.

Sony A95L offers excellent tools for professional screen calibration, allowing you to maximize the capabilities of the IMAX Enhanced mode. We used them to bring the image to a level that will satisfy even the most demanding viewers. After calibration, the white balance for both 4K HDR and SDR content looks simply great – almost perfect. The Colour Checker test confirmed that deltaE errors do not exceed a value of "2", which means that color reproduction is extremely accurate, and any deviations are practically imperceptible to the human eye.

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

As a result of the calibration, A95L Sony offers excellent experiences, whether you're watching material from regular television or your favorite movies. Every detail is reproduced exactly as the creators intended – without unnecessary brightening, with perfectly rendered colors and appropriate depth. This shows that this television, after professional tuning, is capable of competing with the best screens on the market, offering an image that truly impresses.

In this section, we will revisit the smooth transition function while also examining how the TV handles lower-quality content. As we’ve found, the setting responsible for smooth gradation is generally effective, though it does have its drawbacks. While the function works well in SDR content, it becomes less useful in HDR content. Even at the lowest setting, it can blur important details, so we advise against using it in such cases.

The image scaling on the LG B4 is assessed moderately positively. While there is no noticeable edge doubling, the image tends to be somewhat "soft." This can be adjusted by tweaking the sharpness slider to improve the clarity.

The tonal transition smoothing function in Sony A95L works really well and is worth noting. We recommend setting it to the "Medium" level because at this value, you achieve an ideal compromise – there are no artifacts, and the image looks extremely natural and pleasant to the eye. This allows for smooth transitions between different shades while maintaining scene detail, which further enhances viewing comfort.

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

The maximum refresh rate on the LG B4 is 120 Hz, the bare minimum for those requiring high image fluidity. The manufacturer has equipped the TV with a multi-stage motion smoother called "TruMotion." This feature is split into two sliders: one controls the sharpness of moving images (De-Blur) and the other adjusts judder (De-Judder). Both sliders can be set between 0 and 10, with each level affecting the smoothness, so users can easily find their preferred setting.

The LG OLED B4 panel boasts an impressive average response time of 0.1 ms (based on our measurements), delivering an exceptionally clear image that surpasses the capabilities of LCD TVs, which often have response times of several milliseconds. This is particularly noticeable in the "UFO Test" images, where no trailing blur is visible behind moving objects.

Sony A95L is a TV that should satisfy both gamers and movie lovers. When it comes to watching movies, this model is equipped with Motionflow technology, which allows precise adjustment of whether we want the image to be more "framey," like in traditional cinema, or exceptionally smooth, like in cinema TVs. The "Smoothness" slider allows you to regulate the level of smoothness – from subtle changes to a more noticeable effect, while the "Clearness" slider is responsible for reducing flicker and artifacts, helping to achieve more natural and clearer motion. Regarding 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 sharpness. Overall, the TV performs great – both with fast-paced gaming and emotionally charged movie sequences.

The LG B4 has four full HDMI 2.1 ports, each providing 48Gbps bandwidth. This ensures smooth activation of all relevant features without issues, making the television highly suitable for gaming. With its low input lag and extensive functionality, including well-implemented HGIG mode and Dolby Vision gaming with low latency, the B4 is a strong contender for gamers who demand high quality.

A standout feature is GameBar, which allows for on-the-fly adjustments without interrupting gameplay, as well as image adaptations for those with visual impairments. Another key point is that when VRR technology is enabled, the television maintains its contrast, thanks to the OLED panel's structure, though slight flickering in grey shades is to be expected.

In conclusion, the LG B4 is an ideal choice for gamers, seamlessly combining high performance with excellent gaming features. Its 120Hz panel and HDMI 2.1 ports make it a standout option for those seeking top-tier gaming experiences.

Sony A95L is a television that will truly satisfy gamers, thanks to several key features that set it apart from the competition. First of all, a 120 Hz refresh rate – this is something that anyone who loves fast action games, racing, or dynamic shooters will appreciate. This ensures exceptionally smooth visuals, making gameplay more satisfying without annoying stutters. The A95L Sony also has an ALLM (Auto Low Latency Mode) feature that automatically activates low latency mode when we start up a console. What does this mean? Above all, faster on-screen responses, which is invaluable in games where every second counts. Additionally, there’s VRR (Variable Refresh Rate), which adjusts the refresh rate to match the frame rate generated by the console. The result? No tearing, and everything looks smooth and consistent – even with fluctuating FPS.

It’s worth mentioning the support for Dolby Vision with low input lag in games – something we don’t often encounter in televisions, yet it’s included here. This makes the visuals in HDR-enabled games incredibly vibrant, with rich colors and excellent contrast. Both the brightest and the darkest details are visible, making everything look just as the game developers intended. And let’s not forget the "Game Bar" – a small but very practical feature. It gives us quick access to all the important gaming settings, such as VRR and latency information. There’s no need to interrupt gameplay to adjust settings – everything is at hand.

However, it is important to remember that the A95L offers only two HDMI 2.1 ports with full bandwidth, one of which is designated for eARC. This may pose a limitation if we plan to connect multiple devices – for example, a next-gen console and a soundbar simultaneously. In such cases, the eARC occupying one of those ports may be somewhat troublesome, blocking the ability to connect a second console.
