Compare: LG QNED87T6B vs Sony X90L

LG QNED87T is a television that definitely stands out. It is somewhat unconventional – it doesn’t forcefully compete with top OLED models, but it makes up for that with modern features and user-friendly operation. This is a device that works wonderfully for those who value convenience and versatility. The 120 Hz panel, VRR, and ALLM ensure that the television handles dynamic content well. Games run smoothly, the picture is sharp, and the responses are quick. If we spend time on a console, we will appreciate the lack of delays or blurring. When watching sports, fast actions are clear, without stuttering. On a daily basis, LG QNED87T is simply comfortable. WebOS operates intuitively, applications launch quickly, and the Magic Remote significantly simplifies control. Voice control saves time, especially when searching for films or series. Features such as USB recording and Bluetooth offer more options, increasing its versatility. The IPS panel is a significant advantage when it comes to viewing angles. Regardless of where we sit in the room, the picture looks good. It’s an excellent solution in larger spaces, where not everyone has a direct view of the screen. Older films or standard television from built-in tuners also look decent – the improvement in the quality of lower resolution materials works surprisingly well. However, there are certain things that may stand out. The contrast is simply tragic. In dark scenes, there are no details at all. In the evening, in a dimmed room, this is very noticeable. During the day, these imperfections are less felt, so LG QNED87T is better suited for well-lit places. LG QNED87T is a television that has its strengths. It handles dynamic materials well, is comfortable to use, and is perfect for bright rooms. It is not an ideal model for evening screenings in darkness, but in everyday use, it certainly stands out. It is a versatile device that is worth considering when choosing a new television.

Sony X90L is a higher-end model from the Japanese manufacturer that premiered in 2023, but it will successfully continue into 2024 as well. The Sony brand and the name Bravia are associated with excellent picture quality, and this model confirms that reputation – it offers great brightness and very good black levels. Despite having fewer local dimming zones than its competitors, it makes up for this with an advanced algorithm. Additionally, after calibration, the television presents very well-rendered colours, resulting in a natural and cohesive image reminiscent of IMAX cinema. In everyday use, X90L performs excellently, mainly due to the image processor, which effectively scales lower resolution content, and the recording function from the built-in tuner, which is becoming increasingly rare in today’s televisions. Sony is also closely linked with the world of PlayStation, and in this regard, X90L Sony does not disappoint. It is equipped with HDMI 2.1, VRR, ALLM, and a convenient Game Bar, making it a good choice for gamers who expect smooth gameplay and quick response times. However, even in such a successful model, there are some drawbacks. Gamers may be disappointed by the lack of support for HGiG, which could enhance image quality in HDR games. Furthermore, Sony has yet to introduce an update that would reduce input lag in Dolby Vision mode – something achieved in the higher model, the A95L. Those who prefer slimmer devices should know that although Sony X90L looks elegant thanks to its aluminium frame, it is not one of the thinnest televisions on the market. Even though X90L is already a year old, it remains a solid piece of equipment that combines good picture parameters with functionality and support for gamers. It is a successful choice for those seeking a versatile high-end television.

In the category of black levels and contrast, the television LG QNED87T6B has certain challenges to overcome. Equipped with an IPS panel, it does not match models with VA panels in terms of performance in this area. Additionally, the edge-lit dimming affects its poor results in this category. It is worth mentioning that the exception here is the 50-inch variant, which has a VA panel, and is not subject to this test.

Although the manufacturer offers a dimming control option, the effects remain relatively weak. Test patterns show that the contrast is truly miserable, and in the test scene from the film "Sicario 2," it is clearly visible how the television struggles with uneven backlighting, illuminating a large portion of the screen from below. This demonstrates that in more demanding scenes, the television has difficulties maintaining an appropriate level of contrast and black levels, which negatively impacts the overall visual experience.

The Sony X90L television is equipped with a VA panel and in the tested size of 65', it has 88 local dimming zones. It may seem that such a number of zones does not make a great impression, but thanks to the local dimming algorithm, the television handles blacks excellently. This is clearly visible in the first and third test patterns, where the contrast reaches nearly 100,000:1. In more demanding scenes, the X90L does not achieve such spectacular results – a contrast level of 6000:1 is just fine. Light separation performs really well, as confirmed by a scene from the film "Oblivion." However, the small number of dimming zones means that the halo effect is noticeable, especially in the test film from "Sicario 2," where the lights of the helicopter cause quite a significant flare over a large portion of the screen. Despite the limited number of dimming zones, the Sony X90L manages to reproduce blacks quite well. Although it does not match the highest series of miniLED or OLED televisions in terms of black depth and contrast level, it offers solid results that are sufficient for most demanding users.

LG QNED87T6B delivers truly decent visual experiences when it comes to HDR. During our tests on test patterns, the television achieved brightness close to 500 nits, which is a satisfactory result and allows for good visibility of details in high dynamic scenes. Support for basic HDR formats, such as HDR10 and HLG, ensures appropriate image quality. Unfortunately, the television does not support more advanced standards, such as Dolby Vision or HDR10+, which are particularly important at this screen brightness. The lack of support for dynamic metadata means that in certain scenes, the television may struggle to fully reproduce details, especially in very bright areas – precisely when dynamic metadata could significantly improve image quality. Nevertheless, it is worth noting the excellent coverage of the wide DCI-P3 colour gamut, reaching as high as 96.4%. This ensures that the colours displayed by the QNED87T6B model are more vibrant and natural, enhancing the quality of 4K content with a wide colour palette.

HDR on the Sony X90L TV looks promising. The luminance chart showed that the television has a solid power reserve, reaching a maximum of 1000 nits in synthetic tests. However, how does this perform in real-world scenarios? In scenes such as the opening of Life of Pi or the final sequence from The Meg, the TV is able to deliver this power on HDR content, reaching about 800 nits. Unfortunately, displaying small light elements on a black background, as seen in the scene from Sicario 2, poses greater challenges for the X90L – here the results drop to around 600 nits. Despite this, when compared to competing models with mini-LED technology, the effect looks very good and can shine just enough to impress us. Notably, the colour gamut coverage is commendable, with a score of 96% for DCI-P3 and 76% for BT.2020, indicating good colour reproduction in HDR content.

The colour reproduction in the LG QNED, even in Filmmaker Mode, which is the best factory setting, is not without flaws. The main issue is the white balance – we noticed that the level of blue on the graph tends to decrease. This results in a shift towards yellow tones, making the image appear warmer than it should. This deviation affects the naturalness of colour reproduction, especially in scenes with a white or neutral background. The Color Checker test confirmed that some colours are distorted and deviate from reality. Such distortion can make cinematic scenes seem less realistic, and details are represented in incorrect colours, which negatively impacts the overall picture quality.

In terms of contrast, the analysis of the gamma graph revealed significant drops, while the optimal value should be 2.4. This means that the television may display darker parts of the image brighter in certain scenes, which reduces their depth and dynamism. Additionally, on the EOTF curve, which is responsible for brightness reproduction, an unnatural drop was noted at the beginning. This phenomenon may result in less accuracy in reproducing dark scenes, which in turn affects the overall picture quality. The television may not convey the full depth of black, causing more demanding scenes to lose realism and detail. As a result, viewers may notice that details in the darker areas of the image become less distinct.

The best mode in Sony televisions is the IMAX Enhanced mode. Although IMAX is mainly associated with the cinematic experience, here the colour reproduction out of the box is average. In the case of lower quality content, such as HD – regular television or YouTube – it is worth paying attention to the white balance. It is characterised by a deficiency in red and an excessive dominance of blue, which gives the image a pinkish hue. The brightness characteristic, or gamma, for HD content is quite decent, but a slight boost could make the image appear washed out and look as if it is behind a light fog.

In 4K HDR content, the situation looks somewhat different. The white balance shows a significant boost in blue, which causes the image to become unnaturally sharp and seem artificial. Such an exaggeration in colour reproduction may not appeal to everyone, especially if one prefers more realistic shades. Additionally, the EOTF curve in Sony X90L appears quite correct at first glance. However, at the end of the graph, some fluctuations can be seen, suggesting that the television is trying to maintain appropriate brightness to avoid overexposing larger elements.

After calibration, the colours in SDR content look very good. The improved white balance translates to natural and harmonious shades in various scenes. Thanks to the precise adjustment of the gamma, details in shadows and bright areas of the image are accurately reproduced. The television performs excellently in everyday use, offering vivid, well-balanced images and solid colour quality in HD quality. The greatest beneficiary here is also the contrast. The gamma chart has been freed from very large errors, so here the television has gained a second face.

As for the white balance in 4K HDR, it has also been significantly improved. However, certain errors still appear at the end of the chart. This could be due to the overly aggressive operation of the television's local dimming, which affects the accurate reproduction of colour in certain scenes. It is difficult to speak here of an improvement in brightness represented by the EOTF curve. Due to its construction limitations, the television has certain disadvantages and we are not able to overcome them. The Color Checker test confirms the issue with colour saturation – despite the television offering a wide colour palette, it is not able to fully convey what the director intended.

Despite these shortcomings, the overall picture quality after calibration is significantly better than before. Improvements in white balance and gamma adjustment make images more vivid, and colours closer to reality.

Sony offers a range of tools for improving image quality, including two additional picture modes that we decided to utilise during testing and to apply calibration to. This solution significantly facilitates the calibration process and is very effective, provided the appropriate tools are available. In the case of HD content, the white balance was almost perfectly aligned – only one shade of grey exceeds the error value of "1", which is an excellent result. The same can be said for the brightness characteristic (gamma), which presents itself nearly perfectly, with microscopic deviations on the order of 0.01.

In the case of 4K HDR content, the situation is not quite so ideal. Although the white balance has been greatly improved, it has not been possible to completely eliminate the dominance of blue colour. Nevertheless, the errors on the Colour Checker test only occasionally exceed the value of "2", which means that image distortions are practically imperceptible. As for the EOTF curve, it is worth activating the filter in the top right corner "EOTF in Films" – the graph looks correct, but the television encounters difficulties when illuminating very small elements, which is due to the limited number of dimming zones. Despite these minor errors, it is thanks to the calibration that the IMAX Enhanced mode on the Sony X90L makes watching films feel like a true cinema experience.

The gradation in LG QNED is quite good, despite minor issues on the colourful dark sky. These slight flaws do not detract from the fact that the gradation is one of the positive aspects of this model. Overall, the television performs well with smooth transitions of colours.

The fluidity of tonal transitions in Sony X90L is excellent. The gradation is beautiful on high-quality sources such as 4K streaming. One can only notice slight cuts on more demanding gradients, but the overall effect is very good and should satisfy even the more discerning viewers.

When it comes to lower quality materials, the gradation looks really good. A feature called "Smooth Gradation" effectively smooths out the most problematic areas of the image without negatively affecting the film grain. For the best effect, it’s worth setting it to a low level. This solution significantly improves the quality of the displayed content and makes watching lower resolution materials more enjoyable and smoother.

In terms of digital processing, the image is displayed without cropping, known as overscanning. Although slight fringing of the branches against the model’s background can be noticed, the overall presentation is very good. Users should be satisfied with the image quality when watching low-quality materials, such as standard television. The television handles this task exceptionally well, providing a satisfying visual experience even with lower quality content.

The Sony X90L television features a tone transition smoothing function known as Soft Gradation, which is extremely effective. Even at the "low" option, the effects are satisfactory, but at the "medium" setting, it works like a dream – we recommend using this option for the best results. The image scaling on the Sony X90L is simply excellent. The image is not overly sharpened, which provides a natural effect and ensures that everything looks cohesive. It's clear that the engineers really focused on this aspect, creating a solution that is impressive and performs well in daily use. Because of this, even when watching content such as regular television or YouTube, where the image is not inherently stunning, one can enjoy a smooth, cohesive, and visually pleasing experience.

The television provides decent smoothness when watching films, thanks to the "Tru Motion" feature that allows for adjustment of the motion smoothing level on a scale from 0 to 10. De-Judder adjusts motion smoothness, while De-Blur regulates motion sharpness. The user has the option to choose between a traditional, cinematic effect with slight judder (lower settings) and a smoother, theatrical image. Although the latter slightly deviates from the cinematic standard, it may be appealing to many viewers.

As for gamers and sports fans, the LG QNED87 television with a 120Hz panel will certainly not disappoint them. And with the use of an IPS panel, the response time is generally better than that of VA panels available at a similar price. This guarantees smoother gameplay and dynamic experiences when watching sports events.

Sony X90L with a 120 Hz panel is an excellent choice for both gamers and cinema enthusiasts. The television is equipped with the Motion Flow smoothing feature, which allows for adjusting motion fluidity using two sliders: "smoothness" and "clarity." The "smoothness" slider controls the level of fluidity in motion, which helps reduce image stuttering, while "clarity" is used to minimize blur and enhance motion sharpness, which is particularly useful in dynamic scenes.

LG QNED offers a range of features that make it an excellent choice for gamers looking for a high-performance television. The television is equipped with four HDMI 2.1 ports, allowing for connection to the latest consoles, such as PlayStation 5 and Xbox Series X, and taking full advantage of features including Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM). With the Game Bar feature, gamers can quickly and easily manage all their game settings without having to navigate through complicated menus. It is possible to adjust parameters such as VRR, ALLM, Multi View, and monitor frame rates. The television also supports G-Sync and FreeSync technologies, which is particularly important for owners of Nvidia and AMD graphics cards. G-Sync and FreeSync synchronise the television's refresh rate with the graphics card. The 120Hz panel ensures incredible motion smoothness and image clarity. Combined with the Black Frame Insertion (BFI) feature, available at 60Hz and 120Hz, gamers can enjoy an even clearer and smoother picture. LG QNED87 is a television that will meet the expectations of even the most demanding gamers, offering modern technologies and features that significantly enhance comfort and satisfaction in gaming.

Sony X90L is a television that performs well in terms of compatibility with consoles and features for gamers. Its 120 Hz panel and two HDMI 2.1 ports with a bandwidth of 48 Gb/s allow for smooth playback of high-resolution games at a high frame rate. Gamers can also take advantage of the ALLM feature, which automatically switches the television to low latency mode, and VRR, which ensures smooth gameplay without image stuttering. The Game Bar is an additional advantage – an intuitive tool that provides quick access to the most important gaming settings and features, facilitating control over gameplay.

Unfortunately, when it comes to HDR in games, the Sony X90L has its limitations. There is a lack of support for HGiG, a standard that many gamers consider crucial for precise HDR reproduction in games. While the television supports Dolby Vision, which could theoretically improve image quality in games, the practical application of this feature is problematic. Dolby Vision in game mode is associated with very high input lag, making gameplay less comfortable and precise movements more difficult. Additionally, it is not possible to enable Dolby Vision alongside VRR. This means that despite its numerous advantages, gamers seeking the ideal HDR in games may feel a sense of disappointment.

LG QNED stands out with an extremely low input lag, which is crucial for smooth and responsive gameplay. For a refresh rate of 120Hz, input lag values do not exceed 6 ms, whereas at 60Hz, the input lag reaches a maximum of 15 ms. These are truly impressive results that ensure player reactions are almost instantly reflected on the screen.

Input lag in Sony X90L can be assessed as decent, although it is not outstanding. In Dolby Vision mode, the television operates only at 60 Hz, and the additional high input lag complicates matters as it makes gameplay practically unplayable. For games at the popular frequency of 60 Hz, the input lag is about 25 ms – this is an acceptable result, but for more demanding gamers, it may prove disappointing.

However, those more advanced gamers who have equipment supporting higher refresh rates can expect better results. With a 120 Hz signal, the input lag drops to around 12 ms, providing significantly better responsiveness and smoother gameplay, meeting the expectations of more demanding users.

The LG QNED television works excellently with a computer, offering very good font readability. As a result, working and browsing content is exceptionally comfortable. The high refresh rate of 120Hz ensures a smooth and vivid image. It combines a large workspace with efficiency, making it a real pleasure to use. However, for more demanding users, the disappointing fact may be that the television has issues displaying fonts on a dark background. Instead of white letters, they take on a greenish hue.

Cooperation with the PC in Sony X90L is at a good level. The X90L television supports chroma 4:4:4, which ensures quite good font visibility, important while working or browsing content on a large screen. Although there are minimal issues with font legibility on a dark background, it is not bothersome enough to pose a major problem in everyday use.

An additional advantage for PC users is the 120 Hz refresh rate and support for G-Sync functionality. As a result, gamers can expect smoother gameplay without the effect of stuttering or tearing, which significantly enhances comfort and the gaming experience.

When it comes to viewing angles, LG QNED87 performs really well. Thanks to the use of an IPS panel, it offers wide viewing angles compared to VA panels. This means that the image remains clear and does not lose quality even at an angle. Although it may not achieve results as perfect as OLED televisions, which maintain colours and brightness regardless of the viewing angle, in the context of LCD QNED87 screens, it stands out positively. This makes it an excellent choice for larger rooms where viewers often watch from an angle.

The viewing angles on the Sony X90L are unfortunately very poor, which is typical for VA panels. The picture quality degrades when viewed at an angle, which can be problematic when watching from a greater distance or with a larger group of people. It's a shame that the manufacturer did not use a coating to widen the viewing angles, which could significantly improve this aspect and make the television more versatile for different room layouts.

During the day, the LG QNED television performs acceptably. It has a satin finish panel that doesn't suppress reflections very well, which can be noticeable in bright rooms. Nevertheless, thanks to quite good brightness of 430 nits, the picture remains visible and readable. Although reflections can be somewhat distracting, the television's brightness allows for comfortable use during the day.

The performance of the television Sony X90L during the day is very good. The satin matrix effectively dampens reflections, which minimises glare and keeps the image clear even in bright rooms. An SDR brightness level of 785 cd/m² allows for comfortable viewing of standard television and lower quality materials regardless of the time of day. As a result, the X90L will perform excellently in both well-lit living rooms and more sunlit spaces.

LG QNED87 Television offers a multitude of features that significantly enhance user comfort. Let's start with the WebOS system, which we believe has the most user-friendly interface among all televisions available on the market. One of its greatest assets is the remote control with an integrated gyroscope, known as the Magic Remote. Thanks to this, navigation is intuitive and fast, making the use of the television a pleasure. WebOS also supports a number of smart features that greatly simplify daily use of the television. Among them, we find AirPlay, which allows easy content streaming from Apple devices such as iPhone or iPad. Additionally, the television supports a wide range of streaming applications, such as Netflix, YouTube, Amazon Prime Video, and many others, providing access to favourite films and series in one place. When it comes to daily usage, LG QNED87 does not disappoint. The television offers a USB recording function, which is increasingly rare in today's models. This allows for recording favourite programmes and watching them at any time. Furthermore, the television has a PIP (Picture-in-Picture) function, although only for one tuner, enabling the viewing of two programmes simultaneously. Connecting additional devices via Bluetooth is simple and hassle-free. The television supports various Bluetooth devices, such as mice, keyboards, or headphones, increasing its versatility and allowing easy personalisation of the user experience. With all these features, the LG QNED87 television is a versatile and convenient device that meets the expectations of even the most demanding users.

Sony X90L offers a rich set of features, starting with the Google TV system, which is the heart of entertainment. This solution provides access to a vast array of applications and streaming services, and the interface is intuitive and straightforward. With the support of a voice assistant, using the television becomes even more convenient – just one command is enough to find your favourite films, series, or music. Google TV operates smoothly and allows for full personalisation, making everyday use enjoyable and hassle-free.

The television also offers a number of user-friendly features. It supports AirPlay and Miracast, enabling easy content sharing from mobile devices. Additionally, other devices can be connected via Bluetooth, which enhances versatility and user convenience. For those who prefer traditional television viewing, there is even a recording feature available without the need for an external decoder, which is a significant advantage for fans of live shows.

In terms of design, Sony X90L may not be the sleekest, but its appearance is impressive thanks to a metal frame that adds elegance. The television is equipped with a base that can be positioned in three different ways, allowing for adjustments according to different spaces and user preferences.

The built-in media player in the LG QNED87 television should not disappoint anyone. It offers rich capabilities when it comes to playing video and audio files. It supports many popular formats, providing versatility and user convenience. The only criticism that could be made is the limited number of supported image formats. However, this mainly concerns those less popular formats, so most users should be satisfied with the player's functionality. For everyday use and typical multimedia formats, the player performs very well.

Sony X90L handles the playback of most popular file formats from USB without any issues, which is a big plus for those who often access external content. However, it is worth mentioning a slight downside – the built-in player does not allow for changing the font colour in subtitles, which may be problematic for some. Fortunately, thanks to the extensive Google TV system, users have a wide range of options. Alternative media players, which offer more personalisation options, can be easily installed.

When it comes to sound, one could say it is moderately pleasant. There is a lack of pronounced bass, and the mid-tones seem somewhat unclean. This is not an ideal situation for audiophiles, but it is worth noting that the television has no trouble playing DTS files. This is a feature that is lacking in many other televisions, so the LG QNED87 deserves praise for this support.

The sound on the Sony X90L is pleasant and clear, and the presence of bass makes the audio richer. The television performs well when playing music, offering satisfactory audio experiences. An additional advantage is the support for Dolby Atmos and DTS technologies, which provide a more spatial and immersive sound. As a result, films, games, and music gain depth and realism, creating a better experience for the user.
