Compare: LG UR781 vs Sony X90L

LG UR781 is currently the cheapest model from the Korean manufacturer. It features an excellent WebOS system, which is the main advantage of this television. It satisfies most users with access to various streaming platforms and capabilities. The TV offers adequate picture quality for its price, which will certainly meet the expectations of many basic users. Although its HDR capabilities are somewhat limited by the lack of Dolby Vision or HDR10+, it supports basic formats such as HDR10 and HLG. The television handles low-quality content quite well, thanks to the smooth transition smoothing feature, which provides smooth and clear transitions, particularly appreciated when watching films from low-quality sources (e.g., free-to-air television). When it comes to gaming, the television has a very low input lag, which is a fundamental criterion. If we are looking for a budget option, it is quite a nice choice for those willing to compromise on a 120Hz panel for the sake of price. Although the brightness of the television is lower than in competing models, and the colour gamut coverage is limited, the LG UR781 still offers impeccable HDR content appearance due to the presence of dynamic tone mapping. With proper calibration, the television can achieve better colour reproduction and optimal sharpness, significantly enhancing comfort and enjoyment while watching.

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 UR781 is a TV with a VA panel that stands out for its good native contrast, significantly better than that of IPS or ADS screens. Thanks to this technology, bright elements on a dark background look natural and there is no issue with distortion. Unfortunately, the lack of local dimming means that in darker rooms, the blacks are not ideal – they take on a bluish hue, which can be noticeable during nighttime viewing.

Despite this, the LG UR781 offers sufficiently good quality in dark scenes, especially for movie fans. The blacks are deeper than those of IPS panels, allowing for a more cinematic experience. The VA panel also provides stronger contrast, making the image look sharper and details in darker shots more visible. It's a solid choice for those who appreciate better picture quality in evening conditions.

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.

In HDR mode, LG UR781 unfortunately does not impress with its brightness. In tests on five screens, the television achieved only around 200 nits, which is quite a low value for HDR standards. This brightness is comparable to levels typical for SDR, which means that HDR effects are not sufficiently vivid, and the picture may look less impressive, especially in dynamic, bright scenes. In HDR mode, it has certain limitations in colour reproduction. This means that colours may not be as intense and rich as in televisions that handle a wider colour gamut better. In practice, this can make the image less vibrant and dynamic, and HDR effects may not be as spectacular as one might expect. Additionally, UR781 LG has some issues with accurate colour representation in HDR mode, which makes content look less lively.

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.

Colour reproduction in LG UR781 in Filmmaker Mode, which although it is the best mode available from factory settings, is not without its flaws. First and foremost, the issue is with white balance, where the graph shows dips in the blue colour level. This phenomenon results in a shift towards yellow hues, making the image warmer than it should be. Such deviation means that the colours on the screen are not reproduced naturally, which may be particularly noticeable in scenes with white or neutral backgrounds. This can be confirmed by the Color Checker Test, which showed that some colours "escape" into other shades, indicating that the LG UR781 TV does not display colours accurately. This distortion can affect visual experiences, making film scenes seem less realistic and details may be displayed in incorrect colours, negatively impacting overall picture quality.

In terms of contrast, analysis of the gamma graph revealed drops to a level of 2.0, while the optimal value should be 2.4. This means that the TV may display darker parts of the image brighter in some scenes, reducing their depth and dynamism. Additionally, on the EOTF curve, which is responsible for brightness reproduction, an unnatural spike was noticed at the beginning. This phenomenon may result in excessive brightness boosting in the brightest parts of the image, leading to a loss of details in very bright scenes.

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.

After calibration, colour reproduction in SDR content is quite good. The white balance has been effectively improved, resulting in natural, balanced hues across different scenes. The gamma has also been adjusted, providing a more precise representation of details in the shadows and bright areas of the image. As a result, the LG UR781 TV performs well in everyday use, offering solid colour quality and clear, well-balanced images in SDR mode.

However, the situation is less favourable for HDR content. The LG UR781 TV does not support a wide colour gamut, which limits the depth and richness of colours that HDR can provide. The EOTF curve deviates from the ideal, leading to excessive highlighting of details in the bright areas of the image. Unfortunately, this approach results in significant colour reproduction errors, as confirmed by tests on the Colour Checker. Additionally, the low brightness level of the panel further negatively impacts HDR image quality, causing the effects of dynamic range to not be fully realised and colours to appear washed out.

Despite some shortcomings in HDR mode, the TV has significantly improved after calibration, especially in SDR content. The enhancement of white balance and gamma has notably increased image quality, providing a more natural and cohesive colour reproduction. Compared to its pre-calibration state, the difference is clear, and the LG UR781 TV now offers better performance in everyday use, particularly in standard dynamic range.

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.

TV LG UR781 handles tonal transitions exceptionally well, delivering very high picture quality in all scenes. Issues with gradation only arise in darker colours; however, they are subtle and not glaringly obvious. People with particularly sensitive eyes may notice these imperfections, but overall, the television provides very smooth tonal transitions.

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.

Let's now address the function of smoothing tonal transitions and its impact on overall picture quality. As illustrated by the photo on the left, this function performs exceptionally mediocre; we chose the "low" level, which does not enhance quality but also does not blur the film grain. There is a possibility to increase the strength of this function, which could soften this gradation, but one must consider that the image will be too softened in certain scenes.

On the other hand, regarding image scaling, the television does not perform outstandingly, which may be particularly noticeable with lower resolution content. The LG UR781 television applies a slight, artificial sharpening boost, making the image appear sharper; however, this mainly results from the application of artificial contours. For some users, this may be an advantage, as they prefer more vivid, pronounced details. However, this is a subjective matter—such an effect may not appeal to everyone, especially if they desire a more natural appearance of the image.

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.

The LG UR781 TV offers quite decent smoothness for movies, thanks to the "True Motion" option, which allows users to adjust the motion smoothing level on a scale from 0 to 10. Users can choose whether they want to maintain a more traditional, cinematic effect with a slight stutter (lower settings) or prefer a smoother image with a theatrical quality, which, although slightly deviating from the cinematic standard, may appeal to many.

In dynamic sports content and gaming, the LG UR781 TV performs worse. The TV has a 60Hz panel, which limits its interpolation capabilities to these values; therefore, smoothness can be improved in films, but motion blur cannot be reduced. Additionally, the lack of support for 120 Hz and BFI (Black Frame Insertion) technology means that fast-moving objects become blurred, and the panel's response time is too slow, negatively affecting clarity in fast scenes. As a result, the TV may not meet the expectations of gamers and sports fans who are counting on a smooth, clear image without motion blur.

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.

When playing on a console, the LG UR781 TV offers several significant features that can affect the gaming experience, but it also has some limitations. On the plus side, it includes ALLM (Auto Low Latency Mode), which automatically optimises the picture settings by switching the LG UR781 TV to low latency mode, which is beneficial for gamers. The TV also supports correct implementation of HGiG, meaning HDR games look as intended by the creators.

Unfortunately, it lacks support for Variable Refresh Rate (VRR), which can result in worse gameplay smoothness, especially in more dynamic games. It also does not support Dolby Vision mode for gaming, which limits HDR picture quality in games using this format. The TV has a 60Hz panel, so it does not support higher frequencies at other resolutions, such as 1080p@120Hz, 1440p@120Hz, or 4K@120Hz, which is a significant downside for gamers expecting smoother gameplay at higher resolutions. There is also no support for G-Sync technology, which limits image synchronisation in games.

On the positive side, the presence of a Game Bar feature allows for quick access to settings for gamers and makes it easier to adjust picture parameters during gameplay.

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.

Measuring input lag on the LG UR781 television turns out very well, regardless of the signal or resolution. Gamers will surely appreciate the manufacturer's efforts, as gameplay in 4K at 60 Hz with HDR enabled achieves only 13 ms of lag. This is an exceptionally low score that provides smooth and responsive experiences, even in fast-paced online games where every millisecond counts.

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.

Displaying text in 4K resolution at 60 Hz is exceptionally sharp, with excellent colour reproduction, meaning that even fine details like grey letters are clearly visible, despite the use of a BGR pixel layout. An input lag of 14 ms ensures quick responses, making the television ideal for work. Unfortunately, the employed 60 Hz panel and lack of G-Sync do not meet the needs of gamers using a computer, resulting in a lower rating for gaming. Nonetheless, the television performs well in office tasks and media viewing, which compensates for its use at work.

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.

A characteristic feature of VA panels is the noticeable drop in image quality at angles. In the case of this model, when viewed at a 45-degree angle, brightness decreases by as much as 70%, which significantly affects the depth of black and overall image quality. The LG UR781 televisions with VA panels do have better contrast when viewed head-on, but their viewing angles are limited compared to other technologies, such as IPS.

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.

Thanks to its satin finish, it handles glare well during daytime viewing, making reflections less bothersome. However, due to its low brightness in SDR mode, which is only 231 nits, it may struggle to display images clearly in brighter rooms, especially on sunny days. Watching in such conditions may result in poorer visibility and reduced image clarity.

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.

WebOS in LG UR781 televisions is a modern, intuitive system that provides easy access to popular streaming apps like Netflix and YouTube, among others. It features a simple interface and supports functions such as Screen Mirroring, AirPlay, and Bluetooth. The system supports the connection of external devices like keyboards and headphones, offering rich personalisation options and advanced multimedia features. Unfortunately, the base model of the LG does not come with a Magic remote (on-screen cursor), which is a shame! It's also worth noting that in the case of this model, WebOS was not particularly responsive and can be a bit annoying.

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.

Television LG UR781 will play most files and video codecs, and when subtitles are added to the film, you can even change the colour or size of the font. The biggest downside is the lack of support for less popular photo formats.

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.

Although the TV offers a certain hint of bass, the overall sound quality is average. The television does not support most advanced surround sound codecs, which limits its capabilities in fully reproducing audio effects. The only support for surround sound is the ability to stream audio to an external device, such as a soundbar, using Dolby Digital Plus.

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.
