Compare: Sony X90L vs LG QNED91T6A

Sony X90L is a premium model from the Japanese manufacturer, which premiered in 2023 but will successfully continue into 2024. 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 blacks. Despite having fewer local dimming zones than the competition, it makes up for it with an advanced algorithm. Additionally, after calibration, the television presents very well-rendered colours, resulting in a natural and cohesive image associated with IMAX cinema. In everyday use, X90L performs excellently, mainly thanks to the picture processor that effectively upscales lower resolution content, as well as the recording function from the built-in tuner, which is becoming increasingly rare in today's televisions. Sony is also strongly linked to the world of PlayStation, and in this regard, X90L Sony does not disappoint. It comes 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 improve image quality in HDR games. Furthermore, Sony has yet to release an update that would reduce input lag in Dolby Vision mode – something achieved in the higher-end model, the A95L. Those who prefer slimmer devices should know that although Sony X90L looks elegant with its aluminium frame, it is not among the thinnest televisions on the market. Even though X90L already has a year behind it, it remains a solid piece of equipment that combines good picture parameters with functionality and support for gamers. It’s a successful choice for those looking for a versatile high-end television.

LG QNED91T is the only MiniLED-backlit TV from LG for 2024 that catches the eye with its innovative use of a VA panel. This is certainly a departure from the established standards of the Korean manufacturer with its top-tier LCD TVs, which typically used an IPS/ADS panel. But the result is positive – the panel combined with local dimming offers really good contrast. Blacks are deep and should satisfy most users. LG 65QNED91T6A is a very bright TV, so placing it in slightly challenging lighting conditions will not pose a challenge for it. In terms of motion fluidity, the QNED91T shows top class. The TruMotion feature works great, allowing for image adjustment according to personal preferences – from a classic, cinematic look to a more fluid effect. And the 120Hz panel makes it ideal for sports or gaming. For the latter, LG has prepared something special – four full HDMI 2.1 ports with a bandwidth of 48 Gbps, allowing for features like VRR and ALLM (and more). This, combined with low input lag, makes this equipment an excellent choice for gaming on a console or PC. Daily use of QNED91T is pure pleasure, mainly thanks to the WebOS system. The interface is intuitive, there's no lack of applications, and the Magic Remote included in the package significantly simplifies navigation through the menu. Operation is fast, and using the TV is comfortable thanks to the voice assistant. Unfortunately, the TV also has its weaknesses. Despite the advantages of the VA panel in terms of high contrast, the algorithms responsible for local dimming of the miniLED zones do not perform very well. In HDR content, there are situations where the picture is either too bright or excessively dark, which is particularly problematic in scenes requiring precision. Additionally - in practice, the differences between standard HDR10 and Dolby Vision are nearly invisible. This is a significant disappointment, especially in this class of TV. Nonetheless, the LG QNED91T is an interesting choice for those who need a TV with high brightness, considerable gaming capabilities, and appreciate the convenience of the WebOS system. If the priority is picture quality in HDR content, such as Netflix, Prime Video, or Max, we recommend considering alternative models, such as OLED B4 from the 2024 line, which is available for a similar price.

The Sony X90L television is equipped with a VA panel and in the tested size of 65', it has 88 backlight zones. It may seem that such a number of zones doesn't make a big impression, but thanks to the local dimming algorithm, the television handles blacks exceptionally well. This is clearly visible on the first and third test screens, where the contrast reaches nearly 100,000:1. In more demanding scenes, the X90L doesn't achieve such spectacular results – a contrast level of 6000:1 is just fine. The light separation performs really well, which is confirmed by a scene from the film "Oblivion". However, the small number of backlight zones means that the halo effect is noticeable, especially in the test footage from "Sicario 2", where the helicopter lights cause quite a significant flare over a large area of the screen. Despite the limited number of backlight zones, the Sony X90L does really well in reproducing blacks. Although it doesn't match the top 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.

QNED91T is a television with MiniLED backlighting, and in the tested size of 65", we counted 160 local dimming zones. The unit we tested, with a "1" at the end, is equipped with a VA panel, which offers significantly better contrast than IPS panels, which - note - can be found in the model LG QNED90T. Therefore, it's wise to be cautious when choosing a version to avoid disappointment regarding contrast. The model QNED90T is rather hard to acquire in Poland, but distribution can vary. Returning to our contrast tests, it performed really well in less demanding scenes. For example, in one of the scenes from the movie "Oblivion," we observed perfect separation of lights - it looked impressive. However, not everything is so straightforward. In a scene from "Sicario 2," we noticed that the screen was noticeably darker, deviating significantly from the reference image appearance. The television effectively eliminates the halo effect (i.e., the glow around objects), but this comes at the cost of brightness - and quite a considerable one at that. Despite these compromises, the contrast of LG 65QNED91T6A is genuinely solid. Of course, as is the case with MiniLED televisions, some limitations must be taken into account, but the overall impression is very positive.

HDR on the Sony X90L television looks promising. The luminance chart indicated that the TV has a solid power reserve, achieving a maximum of 1000 nits in synthetic tests. But 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 capable of delivering that power on HDR content, reaching around 800 nits. Unfortunately, displaying small light elements on a black background, like in the scene from Sicario 2, presents greater challenges for the X90L – here the results reach around 600 nits. Nevertheless, when looking at competitive models with mini-LED technology, the effect looks very good and can shine enough to impress us. The colour gamut coverage is also noteworthy, with a result of 96% for DCI-P3 and 76% for BT.2020, which indicates good colour reproduction in HDR content.

As befits a MiniLED television, LG QNED91T easily exceeds the magical barrier of 1000 nits on the luminance chart. In scenes where light played a key role, the effect was truly commendable. For instance, 1000 nits in the first scene of "Life of Pi" is a really impressive value, and the achieved 600 nits in the third and fifth scenes allowed for a true sense of HDR magic. However, problems arise with very small light elements on the screen, such as the moon, street lamps, or lights. Values around 100 nits - to put it bluntly - are disappointing, as these elements are so dark they are barely visible. The television deserves praise for covering 96% of the DCI-P3 colour gamut and 75% of BT.2020. LG QNED91T leaves us with very mixed feelings, mainly due to the very aggressive dimming algorithms which, while effectively eliminating halo effect, do impact the brightness of smaller elements.

The best mode on Sony televisions is the IMAX Enhanced mode. Although IMAX is mainly associated with the cinema experience, the colour reproduction out of the box is average here. In the case of lower quality materials, such as HD – regular television or YouTube – it's worth paying attention to the white balance. It suffers from a shortfall in red and excessive dominance of blue, which gives the image a pinkish hue. The brightness characteristic, or gamma, for HD content is quite acceptable, but a slight boost can cause the image to appear washed out and look as if it’s behind a light fog.

For 4K HDR content, the situation is somewhat different. The white balance shows a significant boost in blue, which makes the image unnaturally sharp and gives it an artificial feel. Such an exaggeration in colour reproduction may not appeal to everyone, especially if one prefers more realistic tones. Additionally, the EOTF curve in Sony X90L looks quite acceptable at first glance. However, at the end of the graph, there are certain fluctuations that suggest the television is trying to maintain the correct brightness to avoid overexposing larger elements.

All our tests are conducted in the best picture mode on each television. In this case, as usual, it’s the Filmmaker mode. The name of the mode suggests ideal colour reproduction; however, there were noticeable deviations from the correct image. Our unit, in terms of white balance, exhibited a significant drop in blue hues - both in SDR and 4K HDR materials - resulting in a noticeable yellowing of the image, evident in the comparison scenes from a movie with Tom Cruise. As we described earlier, QNED91T has a tendency to brighten the screen. This is confirmed by the gamma, which is quite significantly lower than the reference value of 2.4. Meanwhile, the EOTF curve, which is responsible for brightness in 4K content, showed some issues with the television’s ability to dim the image in the darkest areas, which we could observe in the paragraph describing the quality of the HDR effect. Although the Filmmaker mode is a pretty good "out of the box" mode, it still requires some adjustments.

Sony offers many tools for improving picture quality, including two extra picture modes that we decided to use during testing and apply calibration to. This solution greatly simplifies the calibration process and is very effective, provided you have the right tools. In the case of HD content, white balance was almost perfectly aligned – only one shade of grey exceeds an error value of "1", which is a great result. The same can be said for the brightness characteristic (gamma), which presents almost perfectly, with microscopic deviations of around 0.01.

For 4K HDR content, the situation is not as ideal. Although white balance has been significantly improved, it was not possible to completely eliminate the dominance of blue. Nevertheless, errors in the Colour Checker test only occasionally exceed the value of "2", which means that picture distortions are practically unnoticeable. When it comes to the EOTF curve, it's worth activating the filter in the top right corner "EOTF in Films" – the graph looks correct, but the TV struggles with illuminating very small elements, which is due to the limited number of backlight zones. Despite these minor errors, it's thanks to the calibration that the IMAX Enhanced mode in the Sony X90L makes watching movies feel like a true cinema experience.

LG offers advanced calibration tools in its televisions such as 65QNED91T6A, which we took advantage of. When it comes to white balance, we managed to significantly correct it in SDR content. The picture mode in 4K HDR quality posed greater challenges, which, while still not perfect, looks significantly better than before calibration. The errors on the Color Checker palette and the colour palette are much smaller than in the factory settings. In terms of brightness characteristics, gamma for HD content is practically perfect, with a small exception at the end of the graph. However, the biggest issues the television faced were with brightness in 4K HDR content. Analyzing the EOTF characteristics in films, we noticed that the television manipulates brightness quite a bit, which we could observe in previous tests. Brightness is significantly boosted compared to the graph in the static test, and the television brightens certain scenes to the extent that some smaller details lose definition. Unfortunately, this is caused by an average backlight zone management algorithm in this model. Nevertheless, the calibration yields quite good results, especially regarding accurate colour reproduction.

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

The gradation on LG QNED91T looks very good. There are only slight cutoffs in the brightest scenes, but the television handles blacks very well, providing smooth tonal transitions. As a result, the image is natural and pleasant to the eye, with no visible issues.

The Sony X90L television features a smooth tonal transition function known as Gentle Gradation, which is incredibly effective. Even at the "low" setting, 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 gives a natural effect and makes everything look cohesive. It's clear that the engineers have really put effort into this aspect, creating a solution that impresses and performs well in everyday use. This means that even when watching content like regular television or YouTube, where the image is by nature not stunning, you can enjoy a smooth, coherent, and visually pleasing experience.

When it comes to tonal transitions in lower quality materials, the television offers a well-known feature from LG TVs - "Smooth Gradation". We can control it at three levels: low, medium, and high. We recommend using the medium option, as it handles tonal transitions well without causing noticeable issues with removing the structure of objects or other artifacts.

On the other hand, when it comes to image scaling (upscaling), LG's Alpha processor performs quite well here. The image appears very smooth, with slight jaggedness in some elements, but this does not significantly affect quality. It looks really good, and the overall effect is very satisfying.

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

The television has a refresh rate of 120 Hz, which should satisfy most users in terms of motion smoothness. Additionally, QNED91T is equipped with TruMotion technology, which allows for smoother image display in films. With this feature, we can adjust the "De-Judder" and "De-Blur" sliders. The "De-Judder" slider reduces stutter in films, which is particularly useful when playing content with a lower frame rate, while "De-Blur" helps to reduce motion blur in fast scenes, which is important for sports or dynamic shots.

Sony X90L is a TV 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 high frame rates. Gamers can also take advantage of the ALLM feature, which automatically switches the TV to low latency mode, and VRR, which ensures smooth gameplay without frame tearing. The Game Bar is an added bonus – an intuitive tool that provides quick access to essential settings and gaming features, making it easier to control the gameplay.

Unfortunately, when it comes to HDR in games, the Sony X90L has its limitations. It lacks support for HGiG, a standard that many gamers consider crucial for accurate HDR representation in games. While the TV supports Dolby Vision, which theoretically could enhance image quality in games, the practical implementation of this feature is problematic. Dolby Vision in game mode comes with very high input lag, making gameplay less comfortable and precise movements more difficult. Additionally, Dolby Vision cannot be enabled alongside VRR. This means that despite numerous advantages, gamers seeking the perfect HDR in games may feel unsatisfied.

The LG 65QNED91T6A television is equipped with HDMI 2.1 ports with a full bandwidth of 48 Gb/s, providing full support for all the standards needed for gaming on modern consoles. We can count on variable refresh rate (VRR) support and automatic low latency mode (ALLM). This ensures smooth gameplay without delays.

Thanks to support for all popular HDR standards in gaming, such as HGiG and Dolby Vision, we can fully utilise the potential of the PS5 and XBOX One consoles. The television also easily handles lower resolutions than 4K, so even older consoles look good on it. The Game Bar makes it easier to access gaming-related settings, allowing us to quickly and intuitively adjust picture parameters and features for gamers. Additionally, the QNED91T offers NVIDIA GeForce Now functionality, allowing us to play in the cloud without needing a console. However, it's important to keep in mind that this solution is quite costly and somewhat falls behind the Xbox Game Pass, which is available only on Samsung televisions.

QNED91T LG is a great choice for both less experienced and more advanced gamers looking for a versatile television for gaming.

Input lag in Sony X90L can be rated as decent, although it’s not outstanding. In Dolby Vision mode, the television operates only at 60 Hz, and the high input lag complicates matters because it makes gameplay practically unplayable. For games at the popular 60 Hz frequency, the input lag is around 25 ms – this is an acceptable result, but for more demanding players, it may turn out to be disappointing.

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

Input lag on QNED91T is really very low, even in Dolby Vision mode. This means we can expect a quick response time, which is very important in fast-paced games, where every millisecond counts. Regardless of whether we are playing in standard mode or HDR, the television offers very good results that will satisfy even the most demanding gamers.

Collaboration with a PC in Sony X90L is at a good level. The X90L television supports chroma 4:4:4, which provides quite good text visibility, essential for work or browsing content on a large screen. Although there are minimal issues with font readability on a dark background, it is not problematic enough to be a significant concern in everyday use.

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

When it comes to gaming on a computer, LG QNED91T synchronises effortlessly with NVIDIA graphics cards and supports G-Sync functionality. The very low input lag makes gaming with a personal computer a real joy. The TV supports chroma 4:4:4, which provides excellent text readability. While we did notice slight blurring of fonts around the edges, overall the image looks very good, and readability is at an acceptable level.

The viewing angles on the Sony X90L are unfortunately very poor, which is typical for VA panels. The image quality deteriorates 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 the manufacturer didn't apply a coating to widen the viewing angles, as this could significantly improve this aspect and make the TV more versatile for different room layouts.

As we mentioned in the paragraph about contrast, the television is equipped with a VA panel, which generally offers very good contrast compared to IPS panels. Unfortunately, VA panels have their weakness in the form of limited viewing angles, which is also evident in the case of QNED91T LG. The viewing angles here are not the best, and while the use of an angle-enhancing coating could significantly improve the situation, unfortunately, we don’t have that here. As a result, the picture loses quality when viewed from a greater angle, which can be problematic when more people are watching at the same time.

The performance of the Sony X90L television during the day is very good. The satin matrix effectively reduces reflections, which minimizes 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. This means that the X90L will work great in both well-lit living rooms and in sunnier spaces.

The TV LG 65QNED91T6A is equipped with a satin panel, which handles direct light reflections, such as from lamps or wall sconces, moderately well. In the first test photo with a large lamp, you can see how the reflection "spills across the screen." However, the QNED91T makes up for it in terms of brightness - an average SDR brightness of 580 cd/m² is sufficient for watching television even in more challenging lighting conditions. Because of this, despite issues with reflections, the TV performs well during the day.

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 apps 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 movies, series, or music. Google TV operates smoothly and allows for full personalisation, making everyday use pleasant and hassle-free.

The television also offers a range of practical features. It supports AirPlay and Miracast, enabling easy content sharing from mobile devices. Additionally, you can connect other devices via Bluetooth, which enhances versatility and user-friendliness. For those who prefer traditional TV viewing, there’s even a recording feature available without the need for an external decoder, which is a significant advantage for fans of live programs.

In terms of design, Sony X90L may not be the slimmest, but its appearance is impressive thanks to the metal frame that adds elegance. The television comes with a stand that can be set up in three different ways, allowing you to customise its placement to suit various spaces and user preferences.

The most important thing in today's televisions, apart from picture quality, is the operating system. The one available in LG models is really very good. Of course, we're talking about the WebOS system, which offers most of the popular apps available in Poland, much like GoogleTV. What sets this system apart is primarily the excellent remote control with an accelerometer - the Magic Remote, which resembles a magic wand. Controlling with this remote is incredibly convenient. Additionally, the television offers a very good voice assistant that understands Polish perfectly.

In terms of user features, the television offers practically everything one could wish for. Here we find the ability to record programs from built-in tuners, support for AirPlay to connect an iPhone, and a mirroring function. We can easily connect keyboards, mice, or headphones, although keyboards are not essential thanks to the handy Magic Remote. Unfortunately, the PiP (Picture-in-Picture) feature is missing here, but it's such a specific function that only those who really need it will feel its absence. The QNED91T is a television that does not disappoint when it comes to daily enjoyment of its use.

Sony X90L easily handles playback of most popular file formats from USB, which is a big plus for those who often reach for external content. However, there is a minor 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 advanced Google TV system, users have a wide range of options. You can easily install alternative media players that offer more personalisation options.

The built-in player in QNED91T should satisfy most users. It handles Polish characters without issue and plays movies with subtitles from external drives. The player also manages most audio formats and photos, except for Apple HEIC files.

The sound on the Sony X90L is pleasant and clear, and the presence of bass makes the audio fuller. The television handles music playback well, offering satisfying audio experiences. An additional advantage is the support for Dolby Atmos and DTS technology, which provide a more spacious and immersive sound. This makes movies, games, and music richer and more realistic, creating better experiences for the user.

LG QNED91T comes with a set of 4 speakers in a 2.2 configuration with a total power of 40W. The TV sounds quite pleasant, and the subtle bass is noticeable. Of course, it's not on the level of an external audio system, such as a soundbar or home theatre, but it's sufficient for everyday use. It's also worth praising the support for audio formats DTS:X and Dolby Atmos, which significantly enhance the audio experience.
