Compare: Sony X85L vs LG QNED91T6A

Sony X85L is a model from 2023 that will be continued in the offering for 2024 by the Japanese manufacturer. Its greatest advantage is the Google TV system. It currently provides the largest access to applications, so we need not worry that one of our favourite applications will be missing. The intuitive interface and voice control feature using Google Assistant make daily use of the television comfortable and modern. As for picture quality, Sony X85L performs well. Thanks to local dimming (albeit with a very average number of zones), black levels look quite decent. Additionally, its fairly high brightness allows for comfortable television viewing during the day, even in well-lit rooms. Furthermore, the television offers a programme recording function with built-in tuners, which is a great convenience for those wanting to control what and when they watch. In terms of motion smoothness, X85L does not disappoint either. The 120 Hz panel and Motionflow system ensure smooth display of dynamic scenes, satisfying both movie enthusiasts and sports fans. The television is also equipped with a range of features for gamers, including VRR, Game Bar and G-Sync support, making it an attractive choice for gaming enthusiasts. Of course, the television is not without its faults. The lack of HGiG support and high input lag in Dolby Vision mode can be disappointing for more demanding gamers. Additionally, the compromise between font readability and image smoothness when connected to a PC may not appeal to everyone. Nevertheless, Sony X85L is a decent piece of equipment that is particularly worth attention if it can be purchased on promotion.

LG QNED91T is the only MiniLED backlit television from LG for 2024, attracting attention due to its innovative use of a VA panel. This is a certain departure from the previous standards of the Korean manufacturer in its top LCD televisions, which usually featured an IPS/ADS panel. However, the effect is positive – the panel combined with local dimming offers really good contrast. The blacks are deep and should satisfy most users. LG 65QNED91T6A is truly a bright television, so placing it in somewhat challenging lighting conditions will not pose a challenge for it. In terms of motion fluidity, the QNED91T shows top class. The TruMotion feature works excellently, allowing for adjustment of the image to personal preferences – from classic, cinematic looks to a smoother effect. And the 120Hz panel makes it ideal equipment 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 you to enjoy features like VRR and ALLM (among others). This, combined with low input lag, makes this equipment an excellent choice for gaming on console or PC. Everyday use of QNED91T is pure pleasure, mainly thanks to the WebOS system. The interface is intuitive, there are plenty of applications available, and the included Magic Remote control significantly facilitates navigation through the menu. The operation is quick, and using the television is comfortable thanks to the voice assistant. Unfortunately, the television also has its drawbacks. 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 their best. In HDR content, there are situations where the image is either too bright or excessively dark, which is particularly troublesome in scenes requiring precision. Additionally, in practice, the differences between standard HDR10 and Dolby Vision are almost imperceptible. This is a significant disappointment, especially in this class of television. Nevertheless, the LG QNED91T is an interesting choice for those who need a high-brightness television with considerable gaming capabilities and value the convenience of the WebOS system. If image quality in HDR content, such as Netflix, Prime Video, or Max, is a priority, we recommend considering alternative models, for example, OLED B4 from the 2024 line, which can be purchased for a similar price.

The Sony X85L television is equipped with a VA panel, which in itself offers quite good contrast. Additionally, this model features local dimming technology – in the 55-inch version, it encompasses 24 zones. Although this number is not impressive, it naturally increases with the size of the television. The contrast in the X85L is good, though not the best, especially in comparison to other televisions also equipped with advanced local dimming technology. Results at a level of 8000:1 are satisfactory, but appear average in the context of competition. In some cases, such as the third scene from the film Arrival, the contrast is promising and performs fairly well. This is thanks to the very good dimming algorithm that Sony has employed in its televisions for years. Unfortunately, due to the limited number of local dimming zones, the television struggles with noticeable blooming, which can be observed, for example, in scenes with the helicopter from the film Sicario 2.

QNED91T is a television with MiniLED backlighting, and in the tested size of 65", we noted 160 zones of backlighting. The specimen we tested, with the "1" suffix at the end, was equipped with a VA panel, which offers significantly better contrast than IPS panels, which - note - can be found in the LG QNED90T. Therefore, it is worth being cautious when choosing a version to avoid disappointment in terms of contrast. The model QNED90T is rather difficult 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 scene from the film "Oblivion", we observed perfect light separation - it looked impressive. However, not everything is so straightforward. In a scene from "Sicario 2", we noticed that the screen was noticeably darker, significantly deviating 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 substantial one. Despite these compromises, the contrast of the LG 65QNED91T6A is really solid. Of course, as is the case with MiniLED televisions, one must reckon with certain limitations, but the overall impressions are very positive.

The Sony X85L television offers solid HDR performance with a brightness level of 750 nits, which is sufficient to enjoy vivid effects. In scenes of moderate difficulty, such as the first, third, or fifth test scenes, a brightness of around 600 nits allows one to fully experience the HDR effect. Unfortunately, in more demanding segments, like the scene from the film Sicario 2, the television reveals its limitations. Drops in brightness to 250 nits cause the HDR effect to lose its impressive quality, resembling rather ordinary SDR. Nevertheless, it is worth highlighting the very good coverage of the DCI-P3 colour palette at 95%, which definitely deserves praise and positively impacts the overall image quality.

As befits a MiniLED television, LG QNED91T easily surpasses the magical barrier of 1000 nits on the luminance chart. In scenes where light played a key role, the effect was truly decent. For instance, 1000 nits in the first scene of "Life of Pi" is an impressive value, and the 600 nits achieved in the third and fifth scenes allowed one to feel the true magic of HDR. However, problems arise with very small light elements on the screen, such as the moon, street lamps, or lights. A value around 100 nits - to put it bluntly - is disappointing, as these elements are dark enough to be 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 the halo effect, negatively impact the brightness of smaller elements.

The television Sony X85L was tested in IMAX Enhanced mode, which, although associated with world-class cinema, does not guarantee an image that aligns with the director's intention. The main problem is the white balance – there is a noticeable strong dominance of blue colour and significant shortcomings in red. As a result, the picture becomes unnaturally cool and looks artificial. Errors in colour reproduction were confirmed by the Colour Checker test, which showed considerable discrepancies – the colours were "scattered" like shots from a rifle, and only a few samples hit the target values. This clearly demonstrates that the accuracy of colour reproduction leaves much to be desired.

The brightness of the image is one of the positive features of the television. The gamma for HD content is at an acceptable level, although there are minor errors, but generally it is quite good. However, the characteristic of brightness for 4K materials remains a problem, controlled by the EOTF curve. It is evident here that very small, bright elements of the image are too dim, which is the result of the limited number of backlighting zones due to the design of the television.

All our tests are conducted in the best picture mode on each television. In this case, as usual, it is the Filmmaker mode. The name of the mode suggests ideal colour reproduction; however, there were noticeable deviations from the correct image here. Our unit, in terms of white balance, displayed quite a strong dip in blue hues - both in SDR and 4K HDR content - which resulted in a distinct yellowing of the image, visible in comparison scenes from the film with Tom Cruise. As we mentioned earlier, QNED91T has certain tendencies to brighten the screen. This is confirmed by gamma, which is quite significantly below the reference value of 2.4. Meanwhile, the EOTF curve, responsible for brightness in 4K content, showed some issues with the television's dimming in the darkest areas, which we could observe in the paragraph describing the quality of the HDR effect. Although the Filmmaker mode is quite a good "out-of-the-box" mode, it too requires some adjustments.

Thanks to the application of calibration tools offered by Sony X85L, the image quality has been significantly improved. After calibration, the white balance for HD content is much more stable, making colours appear more natural and enhancing the authenticity of the image. Although it is not perfect, these changes allow viewers to enjoy a more realistic colour reproduction, eliminating the previous cool tone. The gamma, which was already decent, has been adjusted to an even better version. As a result, tonal transitions and brightness are more consistent, positively affecting the depth and detail of the image.

As for 4K content, despite efforts, the white balance still struggles with a lack of red, which can lead to overly warm colours in some scenes. Synthetic tests showed that the EOTF curve in HDR is quite stable, with a slight enhancement in mid-bright scenes. However, in actual film material, the television can still be too bright with fine, light details, which is a result of the limitations of large local dimming technology.

Nevertheless, calibration has brought significant benefits, particularly in terms of colour accuracy, improving the overall image quality and providing a more natural and cohesive directorial vision.

LG offers advanced calibration tools in its televisions such as 65QNED91T6A, which we utilised. When it comes to white balance, we were able to significantly correct it in SDR content. The picture mode in 4K HDR quality posed greater challenges, which, although still not perfect, looks significantly better than before calibration. Errors on the Color Checker palette and colour gamut are much smaller than in the factory settings. Regarding brightness characteristics, gamma for HD content is practically ideal, with a slight exception at the end of the graph. However, the television had the most trouble with brightness in 4K HDR content. Analyzing the EOTF characteristics in films, we observed that the television manipulates brightness quite heavily, which we could see in previous tests. Brightness is significantly boosted compared to the graph in the static test, and the television lights up certain scenes to the point that some smaller elements lose detail. This is unfortunately caused by the average backlight zone management algorithm in this model. Nevertheless, calibration yields quite good results, especially when it comes to the precise reproduction of colours.

The fluidity of tonal transitions in Sony X85L is at a good level – the gradation of colours is smooth, even in more demanding areas, which makes the perception of scenes positive and natural. The biggest issues arise around shadows, where subtle colour joins may be visible. Despite this, the television performs well enough that most viewers should not notice these minor imperfections.

The gradation on the LG QNED91T looks very good. There are only slight cut-offs in the brightest scenes, but the television handles the black levels very well, ensuring smooth tonal transitions. As a result, the picture is natural and pleasant to the eye, without any visible issues.

In terms of smoothing tonal transitions, the Sony X85L television does not offer any dedicated enhancement options, which is a certain drawback. On the other hand, the image scaling performs quite well – the television adds a bit of artificial sharpness, which may make details such as tree branches more pronounced, although sometimes with noticeable jagged edges. This type of effect may appeal to some viewers who prefer a more detailed image.

When it comes to tonal transitions in lower quality materials, the television offers a well-known feature from LG televisions - "Smooth Gradation". We can control it in three levels: low, medium, and high. We recommend using the medium option, as it does a good job of removing tonal transitions without causing noticeable problems with the removal of object structure or other artefacts.

As for image scaling (upscaling), LG's Alpha processor performs quite well in this regard. The image appears very plastic, with slight aliasing on some elements, which does not significantly affect the quality. It looks really okay, and the overall effect is very satisfactory.

Sony X85L, equipped with a 120 Hz panel, will meet the expectations of a wide range of users – from sports and gaming fans to movie enthusiasts. Movie buffs will certainly appreciate the presence of one of the best motion smoothing systems, known as Motionflow. This system offers adjustment through sliders for smoothness and clarity – smoothness is responsible for motion fluidity, eliminating judder, while clarity improves the sharpness of fast scenes, reducing blur.

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

Sony X85L offers a quite solid set of features for gamers, making it an attractive choice for gaming enthusiasts. First and foremost, the television has a 120 Hz panel, which translates to smooth and dynamic image display, ideal for both fast-paced action games and more demanding sports titles. It is equipped with two HDMI 2.1 ports with full bandwidth of 48 Gb/s, allowing for the full utilisation of next-generation consoles. Additionally, Sony X85L supports VRR (Variable Refresh Rate) technology, which helps reduce stuttering and artifacts during gameplay, providing a smooth experience. The television also supports G-Sync, which is particularly beneficial for gamers using NVIDIA graphics cards, allowing for the synchronisation of the screen refresh rate with GPU performance, eliminating screen tearing. It is worth mentioning the Game Bar feature, which facilitates quick access to the most important gaming-related settings, such as VRR, brightness levels, and display modes, which is convenient and useful during gameplay.

However, there are certain limitations. The television does not support HGiG, which may be a downside for some gamers, as HGiG optimises HDR effect rendering in games, providing a more authentic visual experience. Additionally, while the Dolby Vision mode is available, it is not practical for gaming due to the very high input lag.

The LG 65QNED91T6A television is equipped with HDMI 2.1 ports with 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 games, such as HGiG and Dolby Vision, we can fully utilise the potential of the PS5 and XBOX One consoles. The television also handles lower resolutions than 4K without any issues, so even older consoles look good on it. The Game Bar makes it easy to access gaming-related settings, allowing us to quickly and intuitively adjust picture parameters and features for gamers. Additionally, the QNED91T offers the NVIDIA GeForce Now feature, which allows us to play in the cloud without needing a console. However, it should be noted that this solution is quite costly and somewhat falls short of the Xbox Game Pass, which is available only on Samsung televisions.

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

Generally speaking, the input lag on the Sony X85L is very good, which is crucial for smooth gameplay and quick reactions in games. In standard modes, especially when using HDMI 2.1 and playing at a resolution of 4K at 120 Hz, the input lag is minimal.

Unfortunately, the Dolby Vision mode is an exception to this rule. In this case, the input lag reaches as much as 95 ms. Such a high level of delay makes the Dolby Vision mode virtually unplayable, as the responses to commands are noticeably delayed.

The input lag on QNED91T is really very low, even in Dolby Vision mode. This means we can rely on a fast response time, which is very important in dynamic 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.

The collaboration of the television Sony X85L with a PC is a bit of a balance between image quality and user comfort. If we want to use the television for work, where clear fonts matter, we need to set the refresh rate to 60 Hz. In this mode, the text looks good and doesn't strain the eyes, which is crucial if we intend to spend a longer time in front of the screen.

On the other hand, if the television is to be used for gaming, where we can take full advantage of its capabilities at 120 Hz, we must bear in mind that the readability of fonts noticeably decreases. The image becomes less sharp, and the text harder to read, which can be frustrating. In short – Sony X85L will perform well for occasional connections to a computer, but if we need it on a daily basis for work and gaming, this compromise may not appeal to everyone.

When it comes to gaming on a computer, LG QNED91T easily synchronises with NVIDIA graphics cards and supports G-Sync functionality. The very low input lag makes gaming on a personal computer truly enjoyable. The television supports chroma 4:4:4, which provides excellent text readability. Although we noticed 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 X85L, as is often the case with VA panels, are not the best. The picture looks great when viewed directly, but as soon as you move to the side, you notice that the colours lose intensity and the contrast significantly weakens. This can be an issue if the television is meant for viewing in larger groups, where viewers are seated at different angles. For those who usually watch solo or from one central spot, this won’t be a major downside, but when watching from the side, the picture quality unfortunately declines.

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, a weakness that is also evident in the case of QNED91T LG. The viewing angles here are not the best, and although the use of an angle-expanding coating could significantly improve the situation, unfortunately, it is not present here. As a result, the picture loses quality when viewed from a larger angle, which can be problematic when there are multiple people watching at the same time.

The performance of the television Sony X85L during the day is quite decent. Its satin screen coating handles light reflection moderately well, meaning that in bright rooms there can be some glare, but it is not bothersome enough to significantly interfere. The brightness in SDR mode at 570 nits is sufficient for comfortable TV viewing during the day, even with natural light coming in through the windows. This ensures that colours remain vivid and the picture is clearly visible, making the television suitable for everyday use.

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

Sony X85L runs on the Google TV system, which is a substantial advantage for many users. The television offers wide access to applications, and using streaming platforms is smooth and user-friendly. The interface is intuitive and easy to master, allowing quick switching between applications and searching for favourite content. Google TV allows for personalisation of the home screen, enabling each user to tailor it to their preferences. The Google Assistant further enriches the experience by offering voice control and quick changes to settings or searching for films without the need for a remote.

In terms of user features, Sony X85L offers many useful options. The television has the capability to record programmes, which is a significant convenience for those wanting to watch their favourite content at any time. AirPlay support allows for seamless content streaming from Apple devices, which iPhone and iPad owners will appreciate. Additionally, thanks to the built-in Bluetooth, various devices such as headphones or keyboards can be connected. However, one of the shortcomings is the PiP (picture-in-picture) function, which may disappoint users who prefer multitasking on screen.

The design of the Sony X85L television, while perhaps not among the thinnest, is solid and elegant. The metal stand with adjustable feet is one of its stronger points, allowing the height and width of the television to be adapted to various furniture and spaces. This practical solution enhances the interior and adds a modern character to it.

The most important thing in today's televisions, besides picture quality, is the operating system. The one available in LG models is really very good. Of course, we are talking about the WebOS system, which offers most of the popular applications available in Poland, similar to 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 functions, the television offers practically everything one could desire. Here we find the ability to record programmes 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 convenient Magic Remote. Unfortunately, it lacks the PiP (Picture-in-Picture) function, but this is such a specific feature that only those who truly 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 X85L easily handles playback of most popular file formats from USB, which is a big plus for those who often access external content. However, it should be mentioned that there is a small downside – the built-in player does not allow for changing the font colour in subtitles, which may be troublesome for some. Fortunately, thanks to the extensive Google TV system, users have a wide range of options. Alternative media players can be easily installed, offering more personalisation options.

The built-in player in QNED91T should satisfy most users. It easily handles Polish characters and plays films with subtitles from external drives. The player will also cope with most audio and photo formats, except for Apple HEIC files.

The sound in Sony X85L is good – it is clear across the entire range, allowing enjoyment of both dialogues and music. The bass, though light, is noticeable and adds some depth to the overall sound. However, it should be emphasised that this is a subjective assessment – some may find such a sound profile satisfying, while others might need additional audio equipment to fully experience stronger tones and a more spacious sound.

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