Our verdict

Testing the Sony Bravia 7, we quickly noticed that this TV can do quite a lot. Although it is the "lowest" model from the Japanese manufacturer in the new 2024 lineup, it certainly doesn’t feel like a compromise. The picture impressed us with its deep blacks and the detail in bright scenes – thanks to Mini LED technology, which makes a difference. When we played movies in Dolby Vision, it was immediately obvious how much HDR adds life to every scene. The intense colors and great dynamics made watching evening shows a true pleasure for us. Daily use of this TV also positively surprised us. The Google TV system worked flawlessly, and the choice of apps was so extensive that we easily found everything we wanted to watch. The backlit remote is a small but practical addition – we really appreciated not having to fumble around for buttons in the evenings. The older content we watched improved in quality thanks to advanced image processing. When we tried the TV for gaming, it also made a good impression on us. The 120 Hz refresh rate provided smooth visuals, and the low input lag allowed us to enjoy fast-paced and dynamic gameplay. We particularly liked the Game Bar feature – easy access to settings during the game is something that every gaming enthusiast will appreciate. The TV handled even more demanding titles excellently. However, not everything was perfect. Only two HDMI 2.1 ports, one of which is dedicated to eARC, may pose a problem if someone plans to connect several devices simultaneously. Additionally, when we watched the TV from an angle, we noticed that the picture quality was not as good as when looking straight on – the lack of a layer to enhance viewing angles was noticeable here. Nevertheless, the Bravia 7 is a TV that positively surprised us. It combines excellent picture quality with functionality that works well for both everyday use and evening shows or dynamic gaming sessions. The minor limitations are noticeable, but they do not overshadow the overall experience, which definitely deserves attention from buyers.

Halo effect and black detail visibility:

The Sony BRAVIA 7 television with a VA panel and MiniLED backlighting technology offers excellent black levels. The tested 65-inch variant is equipped with 512 dimming zones, which allows for very good contrast, especially in demanding movie scenes. Naturally, larger TV sizes have more zones, which positively affects contrast and image depth. During testing, in scenes from the movie "Oblivion," the BRAVIA 7 managed to depict dark and bright areas excellently, ensuring decent light separation (the light effect did not merge too heavily into one large spot) from deep black. However, as is often the case with televisions that have local dimming features, certain difficulties arise with small bright light elements. In more demanding segments (e.g., scenes 4 and 5), it can be observed that the television "struggles" to maintain high brightness for these elements, which affects contrast – bright objects are either too dark (in which case contrast results are poor) or a slight halo effect appears around them. In the scene from the movie Sicario 2, the influence of the zones is visible, which causes the aforementioned effect, but it is minimal. Despite these minor imperfections, the overall impressions are positive – the local dimming algorithm works really well, ensuring that the image retains high contrast, and the quality of blacks and details is satisfying.

The LG B4 employs OLED panels produced by LG Displays, offering perfect contrast and true black levels. This results in an image so vivid and dynamic that it can appear almost three-dimensional. The "B" series has consistently been an ideal choice for those seeking excellent image quality without the premium price tag associated with higher-tier models. Thanks to competitive pricing, the B series often rivals Mini LED televisions, frequently emerging victorious. Unlike LCD TVs with local dimming, the LG B4 avoids common issues like blooming, halo effects, or dimming of fine bright details.

This superiority is particularly evident in challenging test scenes, such as those from Oblivion and Sicario 2. The LG B4 handles these with impressive finesse, delivering a high level of visual depth. In Oblivion, the bright lights are distinctly separated, maintaining clarity and precision without blending into each other. Similarly, in The Sicario 2, scenes featuring heli highlight the B4's ability to render intricate details and preserve the film’s unique colour grading, even in darker, more demanding moments. This exceptional performance in both contrast and detail demonstrates the LG B4’s capability to bring cinematic experiences to life.

Since we know that the television performs well with contrast, let's check how it fares in terms of HDR effects. The luminance graph shows the very high capabilities of this model – 1500 nits is truly an impressive result. HDR effects are particularly striking in scenes where most of the screen is covered in light, as seen in the 1st, 3rd, and 5th test scenes. Minor shortcomings, typical of this technology, are still noticeable with very small light effects, such as in the scene from the movie "Sicario 2," where brightness drops to 500 nits. Although these are not stunning results, they can be considered decent. Additionally, it is worth praising the television for its high coverage of a wide color gamut – DCI-P3 at 96%, which allows for vibrant, saturated colors.

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.

After calibration

The IMAX Enhanced mode on the Sony BRAVIA 7 television is definitely the best mode available on this model, although it is not without its flaws, as its name might suggest. The biggest issue is white balance – both in HD and 4K HDR content, there is a noticeable dominance of red color, which makes the image take on pinkish shades. This is particularly evident on the tested snow screen, where the pinkish hue becomes very noticeable. Errors in the Colour Checker test also confirm these deviations – although they are not catastrophic, there is a tendency to lean towards warmer tones. As for brightness characteristics, gamma remains at a decent level with a slight bump but without major issues. However, the biggest challenge is 4K materials. It is clear that the EOTF curve is significantly above the reference chart, which causes the image to become too bright.

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.

Color reproduction after calibration

9.1/10

9.3/10

Sony BRAVIA XR70 offers a wide range of tools that allow for customizing the picture to personal preferences, which has enabled us to make significant adjustments to the settings. The white balance has been free of the issue of red hue dominance – snow no longer ends up with pink shades, which was previously noticeable. Although one can detect minor deviations at the end of the white balance chart concerning a drop in blue color, they are acceptable and hard to notice in everyday use. The Colour Checker test confirms that color reproduction errors are no longer as pronounced and rarely exceed a value of 2, which is a very good result. As for brightness, gamma, while not requiring significant improvement, has been slightly adjusted. However, the most notable change has been observed in the EOTF curve – the television no longer has issues with overly brightening the entire image in 4K content. However, upon closer analysis and enabling EOTF characteristics in films, certain limitations of the television arise due to the previously discussed dimming algorithm. Some small elements may be slightly more illuminated, but these errors are so minor that most users will not notice them. Overall, the calibration results are very, very positive.

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.

Smoothness of tonal transitions

9/10

7.4/10

The Sony XR70 TV handles gradation excellently. In the test sequence, only a few scenes show slight issues with tonal transitions in dark areas, however, most of these problems disappear when the gentle gradation option is turned on. Overall, the TV offers great gradation that will satisfy even the most demanding users.

The smoothness of tonal transitions, often overlooked in tests of competing platforms, is a crucial aspect of image quality, especially when watching content with a rich colour palette and complex effects, where textures overlap. This can sometimes result in colour banding or a lack of smooth gradation. The LG B4 performs quite well in terms of smoothing these tonal transitions. However, it has weaker moments, such as bright coloured skies in films like Kingsman and The Martian. Despite these minor issues, they do not significantly detract from the viewing experience. Therefore, we positively assess the quality of tonal transitions in the LG B4.

Since we know that the television performs very well with high-quality materials, it is worth checking how it fares with lower-quality content. Here the television shows its potential, and the applied graphics processor works really well. On the test board with the light bulb, there are no visible issues with color transitions, and the smooth gradation function works very well – we recommend setting it to "Medium".

When it comes to digital processing, or so-called upscaling, the television sharpens the image quite a bit, which leads to slight aliasing, for example on branches in the background, but it does not remove desired details. Nonetheless, the overall appearance is truly attractive and may appeal to most users. However, if we prefer a softer, more plastic image, this effect can be reduced in the settings by adjusting the sharpening level to our personal preferences.

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 Sony BRAVIA 7 television with a 120 Hz panel will satisfy most users in terms of motion smoothness. Additionally, Sony offers the Motion Flow feature, which allows for the selection of three different picture settings, adjusting them to personal preferences: Smoothness – Film: This setting improves motion smoothness, giving the image a more cinematic or theatrical character. Smoothness – Camera: This setting provides even greater smoothness, useful when watching dynamic scenes such as sports broadcasts. Clarity: This setting focuses on minimizing noise and motion artifacts, resulting in a more stable and clear image.

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 Bravia 7 has significantly improved its capabilities for cooperation with consoles compared to previous models. The TV supports variable refresh rate (VRR), which eliminates screen tearing, and it is compatible with graphics cards, ensuring smooth display. The auto low latency mode (ALLM) effectively reduces input lag, which is crucial in fast-paced games. Dolby Vision with low latency additionally provides impressive HDR effects that look great during gameplay.

Sony Bravia 7 also offers a Game Bar feature that provides quick access to settings and allows monitoring of parameters during gameplay. An interesting option is the ability to enable a virtual crosshair on the screen, which can give a slight advantage in shooting games. However, compared to the Bravia 9 model, the HGIG feature in the Bravia 7 does not perform as well, which may be noticeable for more demanding gamers – especially since the HGIG mode is becoming more popular in the gaming world as the preferred method for reproducing HDR effects.

A downside is the lack of support for 1440p@120 Hz resolution, which could make gaming easier for users with less powerful graphics cards. Additionally, the Sony Bravia 7 is equipped with two HDMI 2.1 ports, one of which is often used to connect an audio system via eARC, limiting the number of available ports for connecting next-generation consoles.

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 BRAVIA 7 provides remarkable results in terms of input lag, particularly with 120 Hz materials, where the delay is around 11 ms – this is an excellent result that will satisfy even the most demanding players. The Dolby Vision mode also deserves recognition, which is typically associated with higher input lag, but here it works really well, providing a comfortable gaming experience. However, we deducted 0.3 points for results with values above 20 ms for 60 Hz content, although we believe that for most users, this difference remains more of a placebo effect.

The LG B4 boasts incredibly low latency across all scenarios. Even the most dedicated gamers will appreciate the exceptionally low input lag, which remains at just 5 ms, even during demanding 4K 120 Hz settings with HDR. Notably, latencies are unchanged when Dolby Vision HDR is enabled, a feature that is not always guaranteed by competitors. This consistent performance deserves the highest praise and a strong recommendation.

The Sony BRAVIA 7 TV has poor viewing angles, which is typical for VA panels. The picture quickly loses quality when viewed at a larger angle – colors fade, and contrast decreases. Considering the price of the device, it's a pity that a coating wasn't used to expand the viewing angles, which would certainly improve the viewing comfort from different places in the room.

One of the undeniable advantages of OLED panels, including the LG B4, is their excellent performance during group viewing, maintaining good contrast, colour saturation, and fidelity from different angles. While it doesn’t benefit from MLA technology like other OLED models, the overall performance remains impressive, and owners are unlikely to be dissatisfied. However, it’s worth noting that at sharp angles, a slight greenish tint can be observed. This is a characteristic of WRGB panels from LG that lack micro-lens technology, and unfortunately, this issue cannot be mitigated.

BRAVIA 7 performs excellently when viewed in bright surroundings. The satin finish effectively suppresses reflections, while simultaneously minimal blurring of elements to the sides, resulting in very good visibility during the day. A brightness level of 1000 cd/m² in SDR mode is astonishing and ensures that the image remains clear even in well-lit rooms.

The maximum brightness of the LG B4 in SDR content reaches 370 nits, which is a commendable result for an OLED television, providing comfortable viewing even in well-lit environments. However, there are two important considerations. First, the television's ability to manage reflections is somewhat average, primarily due to the satin finish of the panel. This means that direct light hitting the screen may cause noticeable reflections. Secondly, the screen's brightness when displaying 100% white fill is around 260 nits. This is a noteworthy improvement, as OLED televisions in this price range previously achieved only half that brightness. This enhancement makes the LG B4 well-suited for watching high-brightness content, such as winter sports.

In addition, WebOS supports various features such as screen mirroring, AirPlay, voice search in Polish, and Bluetooth headphone connectivity. An added bonus is the ability to use the television’s speakers and headphones simultaneously, which is particularly beneficial for individuals with hearing impairments. For sports enthusiasts, the system also includes alerts for upcoming matches, ensuring you never miss a broadcast.

The home panel in WebOS is another strength, offering seamless control of all smart devices connected to the home network. For example, users receive notifications when a laundry cycle is completed, enhancing the overall convenience of the system.

In conclusion, while WebOS may have some limitations compared to Android TV, it provides stable and fast performance, supporting most key functions users expect. It's a reliable and straightforward operating system for those looking for an easy-to-use interface for their television.

The built-in player handles most popular video and audio formats, allowing you to enjoy a wide range of content without any issues. Although there are minor shortcomings when playing photos, the Google TV system makes it easy to install other applications that effectively solve this problem and expand the multimedia capabilities of the television.

The default file player in the LG B4 performs well with most photo and video formats, supporting a wide range of popular codecs, including Dolby Vision. However, there are a few limitations that may disappoint some users. For example, the TV only supports two photo formats: JPEG and PNG, which could be a downside for those accustomed to the HEIC format used by Apple devices. Unfortunately, there is no native support for HEIC files, but the built-in AirPlay feature can serve as a workaround for Apple users. Additionally, while the TV can handle most video formats, it does not support the H.266 VVC codec, which is currently not widely used.

Another limitation is the lack of support for TXT subtitles, which may be an issue for users who rely on these for certain content. Despite these minor drawbacks, the LG B4 offers a solid file playback experience overall.

Although the Sony Bravia 7 television is equipped with only a 2-channel speaker system (2.0), there are two speakers for each channel with a total power of 40 W. This provides really good sound quality, and the bass is noticeable, making watching movies and listening to music more enjoyable.

The audio system in the LG OLED B4 is quite decent and performs well within its price range. The bass is noticeable but does not overwhelm the other frequencies, resulting in a balanced sound overall. While the built-in speakers are adequate for casual viewing, it is likely that most users opting for a high-quality OLED display will already have an external audio system to enhance their experience. However, the inclusion of DTS-HD Master Audio and Dolby Atmos codecs adds value, offering more advanced audio support for those who connect external sound systems. This makes the B4 a solid choice for users prioritising image and sound quality.
