Our verdict

LG OLED B4 is an exceptionally versatile device in the semi-premium category. For how else can you describe an OLED television that is so well-priced, and whose price, as history shows, will quickly drop? Perfect blacks and contrast are two things that inevitably hypnotise, and we are sure that anyone who has ever owned a device with this panel will not be able to return to LCD units. The brightness results of the TV in HDR content may seem quite low, however, in this case, due to such a panel, they will appear optically much higher. It is worth noting their stability and uniformity in practically every scene. In this case, a minor downside is the brightness of full-frame content filled with a lot of white. However, we do not consider this a serious issue, as there are not many such instances. The factory colour reproduction also deserves praise, which in our unit is quite decent, but one cannot help but recall the beneficial effect calibration had on the image, allowing the director's intentions to be conveyed in full. LG B4 will be an excellent choice for all sorts of gamers, as well as sports fans. The former will certainly appreciate the rich support in the form of all the conveniences arising from the HDMI 2.1 standard. Meanwhile, the latter will enjoy the advanced motion smoother with multi-level adjustment. And finally, it is impossible not to mention the convenience resulting from the remote control with a built-in gyroscope, which allows it to function like a mouse. The WebOS system, which we will navigate, is incredibly smooth and responsive. It offers a multitude of applications that will be more than sufficient for the vast majority of users. The heart of the LG B4 TV is the advanced Alpha processor, which is responsible for image smoothness and advanced signal analysis. In summary: who is the LG OLED B4 for? It is the perfect device for those expecting the highest possible image quality within a given budget, but not only that. The LG B4 clearly stands out from the competition at its price point, which cannot offer such high-quality image in this price range.

Sony A95L is a TV that has made a huge impression on us. Although a year has passed since its launch, it still deserves a spot among the best models on the market. When it comes to picture quality, it's simply brilliant. Deep blacks, vibrant colours, and excellent brightness in HDR make everything look incredibly realistic. The QD-OLED panel does its job – movies and games look so good that at times you forget it's just a screen. Using the A95L on a daily basis is a pleasure. Google TV runs smoothly, and there are plenty of apps available. The package includes two remote controls: one traditional and the other backlit – a really handy solution, especially in the evenings. Plus, the voice assistant makes life easier, allowing you to quickly search for a movie or control the home from the couch. Gamers will also be delighted. A refresh rate of 120 Hz, low input lag (below 10 ms even in Dolby Vision), and VRR support is a set that will satisfy any gaming enthusiast. And the sound? The Acoustic Surface Audio+ system makes the sound come straight from the screen, providing great, spatial experiences. Of course, there are no perfect things. Two HDMI 2.1 ports (including one for eARC) might be a bit limiting if someone wants to connect a console, soundbar, and other devices. In a bright room, the black can have a slightly cherry hue, which might bother more demanding users. Despite these minor notes, the Sony A95L is a piece of fantastic equipment. The picture, sound, and functionality are top-notch. It's a television that will satisfy both cinephiles and gamers, offering a true premium experience in the comfort of home.

Halo effect and black detail visibility:

LG B4 uses OLED panels produced by LG Displays. The use of this type of panel gives us perfect contrast and black levels. Thanks to these conditions, the image is incredibly three-dimensional, almost as if it were three-dimensional. The manufacturer's series with the letter "B" has always been the ideal solution for those seeking very good image quality while not wanting to pay extra for features that are only available in higher series. Therefore, these models have been somewhat of a dark horse in this price range, as their competitive pricing primarily allowed them to compete with Mini LED televisions. It’s not hard to say that these models have won these battles due to the absence of characteristic flaws found in LCD receivers with multi-zone backlighting, such as blooming/halo effects or dimming of images with fine bright details. And as we can see in the test scenes from the films "Oblivion" and "Sicario 2," the image quality stands at the highest level. Looking at the first one, we see a spectacular play of lights that, despite their brightness, are perfectly separated from each other. Even the more difficult scene with the helicopter poses no problem for LG B4, showcasing a wealth of detail and the specific colour grading characteristic of this title.

Sony A95L is an OLED television that truly impresses when it comes to contrast. With OLED technology, this model offers perfectly deep blacks – in dark scenes, there are no signs of colour bleeding or glow, making images look incredibly realistic. Additionally, QD-OLED technology allows for higher brightness, further emphasizing the difference between bright and dark elements. As a result, in scenes like those from the movies Oblivion and Sicario 2, A95L Sony excels at separating lights from shadows, giving the picture clarity and depth – the perfect solution for those seeking a cinematic experience at home.

LG 55 B4

The brightness results in HDR materials LG B4 are very good. It is true that none of them exceed 1000 nits, although the luminance stability is excellent and looks practically the same in every scenario. The only moment where the tested television performs worse is the last scene, although this should not come as a surprise. Large frames filled with a lot of white have always been, and will likely continue to be, somewhat of a weakness for OLED televisions. However, the combination of perfect contrast, black levels, and brightness in the LG B4 allows for a full spectrum of the HDR effect. Additionally, the incredibly high coverage of the DCI-P3 colour gamut, which reached 99%, deserves recognition. As a result, colours look incredibly vibrant and stunning.

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.

Factory color reproduction

8.4/10

7.9/10

Factory Mode

After calibration

Factory Mode

After calibration

The best factory mode prepared by the manufacturer is "Filmmaker," and we used it throughout the entire testing procedure. We must admit that the unit we received straight out of the box had quite decent colour reproduction. The biggest issue in both SDR and HDR content turned out to be white balance. In the former, there was a strong dominance of red, resulting in a noticeable yellow tint in the displayed image, particularly evident on skin tones and whites. In high-quality materials, this colour was also pronounced, but due to a lack of blue, there were also signs of green visible. Besides these shortcomings, we also encountered issues with greyscale and the colours themselves.

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.

Color reproduction after calibration

9.3/10

9.3/10

LG B4 has been providing very advanced calibration tools in its TVs for years. We can even say that as the only manufacturer on the market, it allows for such deep intervention in image adjustment. Thanks to these, we were able to calibrate the device so well. The evidence of this is the extremely low deltaE errors, which can be said to stand at a reference level. Both SDR and HDR materials now look exactly as the film director intended. It is no coincidence that TVs of this brand are most often used as preview screens for various graphic or post-production 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.

Smoothness of tonal transitions

7.4/10

9/10

The smoothness of tonal transitions, often overlooked in various tests on competitive portals, is an equally important aspect of image quality assessment. It is particularly crucial when watching materials that feature a wealth of colours and many intricate effects, where textures blend together. This often leads to what's known as colour banding, or a lack of smooth gradation. The tested television handles tonal transition smoothing quite well. However, it's worth noting that it has its weaker moments, such as the bright colourful sky in the film "Kingsman" or "The Martian." These, however, are not issues that detract from the viewing pleasure. Therefore, we assess the quality of tonal transitions in LG B4 positively.

The fluidity of tonal transitions in A95L is truly remarkable – it’s one of the greatest advantages of QD-OLED panels. The image appears incredibly smooth, and all transitions between different shades are perfectly rendered, with no noticeable jumps or distortions. As of today, it's challenging to find a panel that handles tonal transition reproduction with such precision. Of course, if someone really looks closely, they might notice slight errors in the black areas, but they are subtle enough that hardly anyone will notice them during normal use of the Sony A95L. For most users, these minor imperfections will be completely unnoticeable, and the fluidity and detail of tonal transitions will satisfy even the most demanding enthusiasts of excellent picture quality.

In this paragraph, we will take another look at the tonal transition smoothing feature, but we will also check how the TV handles lower quality material. As we have managed to check, the setting responsible for smooth gradation works quite effectively, although it has its weaker moments. While the feature works well with SDR content, it becomes less useful with HDR content. Even at the lowest of options, it blurs essential details, so we advise against using it.

The image scaling on LG B4 is rated fairly moderately positively. Although there is no edge splitting, the image itself is naturally "soft". We can change this by adjusting the sharpness slider.

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 B4 is 120 Hz. This is the absolute minimum for those who require high image smoothness. The manufacturer has implemented a multi-level motion smoother called "TruMotion". It has been divided into two separate sliders that adjust the sharpness of moving images (De-Blur) and stuttering (De-Judder). Both sliders can be set in the range from 0 to 10, with each level affecting the degree of smoothness, so everyone can find their sweet spot.

The LG OLED B4 panel features an average response time of 0.1 ms (which directly results from our measurements), allowing for an incredibly clear image, unattainable for LCD TVs, which have response times of even several milliseconds. This can be clearly seen in images from the "UFO Test", showing no trace of blur trailing 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.

The LG B4 television is equipped with four full-fledged HDMI 2.1 ports with a full bandwidth of 48Gbps. All functions corresponding to this standard activated without any issues, and throughout the entire testing procedure, they caused no problems. The combination of such extensive functionality and low input lags leads us to say that the tested television is truly designed for gaming. This is not surprising, considering that the manufacturer has always placed great emphasis on this. Therefore, we can enjoy both a properly implemented HGIG mode and gameplay in Dolby Vision with low latency. Such a tandem will surely attract the attention of all passionate gamers for whom quality is the most important.

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 enables image adjustments for individuals with visual impairments, which is an extremely nice touch. Another important piece of information is that when the VRR technology is turned on, we will not experience a drop in contrast. This is, of course, due to the construction of the panel and the lack 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 the television.

In summary: The LG B4, like all OLEDs from the manufacturer equipped with 120Hz panels and HDMI 2.1 ports, creates a harmonious whole with the console. In practice, it is a complete television, and if we expect the highest possible efficiency in gaming, the B4 will be the 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.

Delay times for LG B4 are incredibly low in every scenario. Even the most passionate gamers will certainly appreciate the very low input lag of just 5 ms at demanding settings of 4K 120 Hz with HDR. It's also worth noting that the latency at the same settings, but with Dolby Vision HDR enabled, remains unchanged, which is not as obvious with the competition. Therefore, it deserves the highest rating and recommendation.

When it comes to input lag, Sony A95L really delivers. Even in Dolby Vision mode, the latency is surprisingly low – results below 10 ms with 120 Hz content are quite impressive. Thanks to such low input lag, gaming is incredibly responsive, and every action in the game is instantly reflected on the screen. For those playing at 60 frames per second, an input lag of 17 ms is also very good. This is a value that practically has no impact on the gaming experience – it falls within the so-called "placebo effect." Sony deserves praise for updating the Dolby Vision Game mode, which solved the issue of high input lag that was present at the TV's launch in 2023.

LG B4 paired with a PC performs excellently due to its very low latency of just 13.5 ms, which is virtually instant response between the mouse, the eye, and the screen. A crucial aspect of working on a display is readability, which in the case of the tested television is very good. However, it's worth noting that to achieve sharp fonts, you need to enable the passthrough option in the settings.

The RWBG pixel layout does not significantly affect the display of fonts or letters, which is a notable advantage over Samsung's QD-OLED matrices. Users of both Windows and macOS equipped computers will certainly be pleased with the performance on the tested television screen.

Sony A95L TV offers compatibility with computers at 4K resolution at both 60 Hz and 120 Hz. In 4K mode at 60 Hz, the readability of fonts is at a good level, making it comfortable to use the TV as a monitor for office work or browsing content.

Unfortunately, when switching to 4K with a refresh rate of 120 Hz, the quality of the displayed text deteriorates – the resolution is reduced by 2 times, negatively affecting the clarity of the fonts. In 4K, fonts lose sharpness, which can make prolonged use of the TV as a computer monitor at higher refresh rates difficult. Of course, the problem disappears if we switch back to 60Hz, but this can be quite inconvenient when the TV forces us to "juggle" the settings.

The undeniable advantage of OLED panels is their efficiency in group viewing, meaning from different angles. LG B4 maintains very good contrast, colour saturation, and fidelity. While it may not match organic TVs supported by MLA technology, it cannot be said that anyone who purchases the device has been dissatisfied with the results. However, it should be noted that at sharp angles, a slight greenish tint can be observed. This is a characteristic feature of WRGB panels from LG, without the aforementioned micro-lens technology, and unfortunately, there is nothing that can be done about it.

The viewing angles on the Sony A95L are among the best on the market, thanks to the QD-OLED panel. With this technology, colours remain vibrant and contrast hardly changes, regardless of the viewing angle. This is a result that even standard OLED panels fail to achieve, making the A95L perfect for rooms where viewers change position or there is a larger group of spectators.

The maximum brightness of the TV in SDR materials is 370 nits. For an OLED TV, this is a very good result, allowing for quite comfortable viewing during the day. There are two things worth noting. The first is the rather average handling of reflections caused by the satin finish of the panel, which means that direct light hitting the TV can be quite intrusive. The second issue is the screen brightness at 100% white fill, hovering around 260 nits, which is an outstanding result, as until recently, OLED TVs in this range could "boast" a brightness two times lower. This means that conditions for watching, for example, winter sports, will be very good.

Sony A95L performs quite well in daytime conditions. The QD-OLED panel effectively suppresses reflections and glare, making viewing comfortable even in bright sunlight. An average brightness of 380 cd/m² is a really good result, especially for an OLED TV – it holds up, although it still can't compete with Mini LEDs, which are unmatched in this regard. One of the issues that may bother some viewers is the characteristic QD-OLED effect, where blacks lose their depth and take on a slightly cherry hue in strong light.

LG B4 uses the well-known proprietary WebOS system that has been around for many years. The system itself offers virtually all the most important applications, and those that are missing can be counted on one hand, such as CDA or KODI.

WebOS also features a highly valued ability to perform operations using a cursor that appears when the remote is in motion. The convenience of such a function is invaluable when entering queries or passwords for portals. WebOS, like most systems, also supports features such as screen mirroring, AirPlay, voice search in Polish, and the ability to connect headphones via Bluetooth. More down-to-earth things, WebOS allows us to use headphones and the TV's speakers simultaneously, which will surely be a great assistance for people with hearing disabilities. Among the more interesting features that will primarily appeal to sports fans, there is the option to turn on an alert informing about an upcoming match, ensuring that we never miss a broadcast. The home panel also deserves praise, allowing control of all smart devices connected to the home network. For example, the end of a washing cycle will be signalled by a notification in the top right corner.

In summary, the WebOS system, although less known and having certain limitations compared to Android TV, offers stable and fast operation and supports most features that users might need. It is a solid solution for those looking for a simple and effective operating system in a television.

Sony A95L runs on the Google TV operating system, which provides easy access to a wide range of apps, streaming services, and various personalisation features. The interface is clear and user-friendly, and the wealth of available apps means that everyone will find something for themselves – from popular streaming services like Netflix, Disney+ or HBO Max, to various music and sports apps. Google TV also supports voice assistant functionality, allowing for easy content search, control of TV settings, and even management of other smart devices in the home – all through simple voice commands.

Sony A95L also offers a range of user-friendly features that make it even more versatile. The TV has the ability to record programs directly to USB memory, a convenient solution if you can't watch something live. It also supports AirPlay, making it easy to stream content from Apple devices, and additionally, you can connect various peripherals via Bluetooth, such as headphones or game controllers. The package includes two remotes – one traditional and one modern, backlit remote, which is particularly useful for evening viewing when the room is dark. It is worth mentioning the lack of PIP functionality, which allows watching multiple TV signals simultaneously.

In terms of appearance, A95L Sony may not be the thinnest OLED TV on the market, but it has its strengths. The package includes a practical stand that can be adjusted in various ways, allowing you to tailor the TV to your needs and space arrangement. Additionally, the manufacturer has included the Bravia Cam, which opens up further possibilities – from video calls to smart features such as optimising image and sound based on the viewer’s position. While it may not be the sleekest, its solid construction and useful accessories make the A95L look really good in any living room.

The default file player in LG B4 definitely handles most photos quite well, although it's surprising that some equally popular ones are missing. We can successfully play videos recorded in practically all the most popular formats, including Dolby Vision. The only codec that LG B4 won’t play is H.266 VVC, although this is currently rather unused. However, it’s worth noting the supported photo formats, which are just two: JPEG and PNG. Apple phone users may feel disappointed by the lack of support for the HEIC format, which is the default format when taking photos. The remedy for this is to use the built-in AirPlay feature. We should also mention the lack of TXT subtitle support.

Sony A95L does quite well when it comes to playing files from USB. The built-in media player will satisfy most users – it’s easy to use and supports popular formats, making it simple to play movies, photos, or music directly from a connected USB drive. The only thing missing is the ability to change the font colour in subtitles, which can be problematic in some situations. Fortunately, the Google TV system allows the installation of other media players that offer more advanced personalisation options, so you can easily customise everything to your needs.

The audio system built into the LG OLED B4 can be considered quite decent. We can say that it holds up fairly well in its price range. The bass is quite noticeable, but it doesn't overpower the other frequencies. It can be said that the sound is reasonably well balanced. We believe that those opting for this class of display are, or will be, in possession of an appropriate audio system. Therefore, the presence of DTS-HD Master Audio and Dolby Atmos codecs is not insignificant.

Sony A95L offers sound that definitely stands out from most televisions. For built-in speakers, the sound is truly impressive – full, with well-balanced bass and mid-tones. Dialogues are clear, and sound effects are well distributed, making the television great for both watching movies and gaming. The Acoustic Surface Audio+ system, which converts screen vibrations into sound, creates a more spatial impression, adding extra depth to the content being viewed.
