Compare: Samsung QLED Q80D vs LG QNED91T6A

Samsung Q80D is a very versatile television. It is certainly a device that can easily adapt to the needs of both gamers and those looking for equipment for everyday viewing. When it comes to the former – that is, gamers – the support for HDMI 2.1, 120 Hz refresh rate, and low input lag make playing on a console or PC pure pleasure. Additionally, the Game Bar feature allows quick changes to settings without the hassle of leaving the game – a small thing, but it makes a difference. It's also worth mentioning the fantastic feature of an efficiently working motion smoother that operates well in games. We get the impression that playing on such a television adds us a few FPS, which translates to an advantage in the game. During everyday use, the Q80D also performs very well. The Tizen system offers access to popular applications like Netflix, Prime Video, and Disney+, so nothing is lacking here. The high brightness of the screen ensures that the television performs excellently even in well-lit rooms. A nice and interesting addition is the solar remote, which not only does not require battery replacement but also allows you to control other devices (e.g., set-top boxes, consoles, soundbars). When it comes to picture quality, the Q80D has a lot to offer. Although it lacks Dolby Vision support, after calibration, the colours look great, and the contrast and black level thanks to FALD (full-array local dimming) have made a huge impression on us, especially considering the television segment. With a VA panel enhanced with quantum dots (QLED), the colours on the Q80D can look truly splendid. Watching movies or series in the evening is a real pleasure – particularly if we care about good detail. However, there are little things that might be bothersome. The lack of a recording feature is certainly a limitation, although it may not be a problem for everyone. Another obvious issue will be its viewing angles. These are typical results for this type of panel, so one must reckon that at the expense of great blacks, the Q80D simply performs average when viewed from the side. Nevertheless, Samsung Q80D is an excellent television that works well in any situation. It offers outstanding picture quality, many useful features, and solid build quality for its price range. A few minor shortcomings do not take away from its charm, as overall it is a model that will comfortably meet the expectations of most users – both those who game on a console and those who simply enjoy evening screenings with good image quality.

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 Samsung Q80D television is equipped with a VA panel, which immediately affects the difference in contrast and black reproduction compared to IPS panels. VA panels offer significantly better contrast and deeper blacks, while IPS panels feature better viewing angles but worse contrast. In the case of the 55" model, the television has 100 local dimming zones, and it's worth noting that this number may vary depending on the screen size. Thanks to local dimming, blacks appear well, but it's important to mention that the algorithm of this technology combined with the limited number of zones can sometimes "go crazy". Bright objects may be dimmed to achieve better blacks. During a test scene from the film Oblivion, the lights blended into a single spot, regardless of the dimming settings, highlighting the limitations of this technology. In the film Sicario 2, large dimming zones were particularly noticeable, for example, with the small lights of a helicopter, indicating how large the areas controlled by a single dimming zone are. Despite these imperfections, local dimming technology still offers significantly better image quality than televisions without this feature or with edge lighting. With the ability to completely turn off individual zones, the television can provide a noticeable boost in brightness in selected areas, which can give the image a cinematic effect, especially in dark rooms.

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.

In the context of HDR, the Samsung Q80D television achieves very positive brightness results in the tested film scenes, where the frame is filled with light, reaching values from 600 to 900 nits, allowing the user to experience a great juiciness of the image. Such results allow the user to feel the difference between HDR and SDR quality. Unfortunately, problems arise in situations where small light effects occur against a dark background. In such cases (e.g. test pattern 4 from the film Sicario 2), a noticeable drop in brightness can be observed, caused by the large sizes of the dimming zones used here. This limitation, combined with the dimming algorithm, affects how the television handles small bright elements against a dark background. At that point, we may perceive an unwanted lack of brightness, and the HDR effect resembles that of SDR.

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.

In "Filmmaker" mode, which is the best choice out of the box, the Samsung Q80D TV shows solid colour reproduction. For SDR content, a visible drop at the beginning of the gamma curve suggests that details in dark scenes may be less pronounced, impacting the overall viewing experience. Regarding white balance in SDR content, while it is generally accurate, significant drops in blue colour when screen coverage exceeds 70% can result in less natural hues in bright and dark scenes. Users may notice that some blue elements in the image may appear less intense, and the overall colour will have a warmer tint.

In contrast, for HDR content, the EOTF curve being above the reference line for most of the time indicates that the TV may struggle with accurately reproducing brightness and details in the brighter areas of the image, which may be disadvantageous for the viewer. It is also worth noting the substantial drop at the beginning of this graph, indicating that the TV has difficulties reproducing brightness in the darker areas of the image, as seen in the contrast and black tests, where several scenes were unable to showcase the full capabilities of the TV's brightness. In terms of its white balance, the initially good results on the graph are promising, but the sharp drop in red colour, which significantly falls down, combined with a large increase in blue colour, may lead to inaccuracies in reproducing certain skin tones and other key colours. This phenomenon may be noticeable to viewers in scenes where colour details are crucial.

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.

The film mode after calibration looks significantly better than the one you can see when taken out of the box. Samsung offers an advanced range of calibration tools in its televisions. Among them are 2- and 20-point greyscale adjustment and CMS (Colour Management System). Both in HDR and SDR mode, the white balance has improved significantly, although there are minor errors at the end of the graph in the case of HDR content. The contrast has also been greatly improved, and the gamma curve responsible for SDR shows better results. However, when it comes to HDR, the EOTF curve in the television seems to be at an ideal level at first glance. Yet, when we delve deeper and enable the EOTF graph while watching films, we may notice that all the lines of the curve are above the reference line. One could even say that the television is "cheating" when playing film materials. Such a situation, where the EOTF curve is above the reference line, makes the screen – although it may seem brighter, which some users may find attractive – lose detail in the darker parts of the image. In practice, this means that in scenes with a lot of shadows or dark elements, the television is unable to accurately render the details that should be visible.

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 tonal gradation in the Samsung Q80D television is at an excellent level and can be considered one of its stronger points. Even in the most demanding scenes from the films we tested, it performs exceptionally well. Any potential issues with smoothing transitions in colours are minimal and subtle. The average viewer will most likely not notice them, which translates to an overall positive visual experience in everyday use.

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.

Samsung Q80D performs very well with low-quality materials. The noise reduction works on the principle of gentle grading, making it very effective in smoothing out unwanted image disturbances. Unfortunately, this same effectiveness also causes elements that should not be smoothed, such as film grain, to become blurred. For those who value a pliable, smoothed image more, this can be seen as a significant advantage, especially for lower-quality content.

When it comes to image scaling, Samsung Q80D stands out positively in this aspect, significantly enhancing viewing comfort. The television handles the conversion of lower-resolution materials well, improving their quality and detail. For example, in the attached image with the model, there are no visible artifacts or excessive fraying of branches, which attests to the advanced image processing technology.

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.

The Samsung Q80D television stands out very positively in terms of motion fluidity and motion blur reduction, primarily due to the applied 120Hz panel and above-average response time of the panel. Users have two options for adjusting fluidity: "Motion Smoothing," which allows for adjustment of smoothness on a 10-point scale, and "Blur Reduction," particularly effective at higher refresh rates, improving the sharpness of rapidly moving objects. In the UFO test, no motion blur is visible behind the moving object, and the image is not cloned forward, indicating a lack of overshoot effect.

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.

The Samsung Q80D television is a true gem for gamers. It is equipped with four HDMI 2.1 ports, which is a rarity, especially in this price range. This allows users to enjoy features such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and 120Hz in 4K resolution. These features ensure smoothness and responsiveness of the image, which is a key aspect during dynamic gameplay. The television also supports HGIG (HDR Gaming Interest Group), enabling optimal display of HDR content in games. Additionally, it is equipped with a Game Bar that allows quick access to gaming settings. Users of Nvidia graphics cards will also be pleased thanks to the implementation of G-Sync. This feature eliminates stuttering and screen tearing. The only downside is the lack of support for Dolby Vision mode, which may be disappointing for users looking for this HDR format. It is also worth mentioning that since 2022, thanks to a partnership with Microsoft, Samsung televisions offer the Xbox Game Pass application, allowing for cloud gaming. This is an additional advantage for gamers who want to access a wide library of games without the need for a console.

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.

There isn't much to say here, the input lag at this level is simply remarkable. It's hard to achieve a better result that will satisfy gamers! The television performed excellently at every tested resolution and refresh rate, both in SDR and HDR.

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.

Samsung Q80D works well as a computer monitor. Thanks to support for 4:4:4 chroma (which only functions in "Game" mode), text on the screen is clear and legible, which is very important for those who want to work on such a television with text documents or spreadsheets. One of the biggest advantages of this model is its exceptionally low input lag in "PC" mode, which is just 9 ms. This is a reference-level result that ensures smoothness and responsiveness, which is crucial for both gamers and those involved in video editing. The only issue we can point out is that there is a certain problem with displaying fonts on dark backgrounds. When we zoom in on the tested font image, we notice that the horizontal lines are darker compared to the vertical ones. This means that the sub-pixels in the television do not fully illuminate in this case. This could be due to an oversight by the manufacturer regarding the optimisation of the algorithm responsible for displaying thin lines, which affects the quality of details in displaying text on dark backgrounds. Nevertheless, Samsung Q80D is a very good choice as a PC monitor.

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.

Samsung Q80D, equipped with a VA panel, unfortunately does not perform well in terms of viewing angles. When we watch the screen at a 45-degree angle, there is a noticeable loss of brightness. The image becomes less sharp, which can be problematic if we plan to watch television from different spots in the room. However, the VA panel has its advantages. When looking directly at the screen, black levels are deep and well-saturated. Furthermore, even at an angle, dark colours maintain their depth, which is a rarity for this type of panel.

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 Samsung Q80D television stands out with very good brightness, averaging 550 nits, which is an impressive result, especially since it maintains this brightness across the entire screen surface. This makes the image clear and well-visible even in bright rooms, which is a big plus when watching television during the day. However, despite the satin coating of the panel, the television struggles somewhat with reducing reflections. In bright lighting conditions, unwanted glares can appear, which may disrupt viewing comfort. This is particularly noticeable when there are light sources in the room directly falling on the screen.

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.

The Samsung Q80D television offers a range of features that significantly enhance user comfort. The Tizen system is an advanced platform that provides users with an intuitive and smooth experience. Thanks to its user-friendly interface, navigation through apps and settings is quick and easy. Tizen supports a rich set of applications, including popular streaming services, allowing access to a wide variety of entertainment content without the need for additional devices, with the novelty for 2024 being support for the Polish language. It is also worth mentioning the solar remote, which is not only eco-friendly but also convenient for everyday use. The solar cell remote can easily control other devices such as home cinemas, decoders (e.g. Canal+), or game consoles, which poses quite a challenge for other manufacturers. Returning to the console, Samsung Q80D offers several features that may appeal to gamers. Above all, the television supports VRR (Variable Refresh Rate) technology, which allows for smoother game displays, eliminating issues like tearing and stuttering. Additionally, due to its low input lag, gaming reactions are quick and precise. The Samsung Q80D is also equipped with a Game Bar function, which allows quick access to key gaming settings without the need to exit the game. From this level, we can check and adjust parameters such as VRR, input lag, frames per second (FPS), as well as screen ratios or sound settings. This enables gamers to continuously optimise their experiences by adjusting settings to the current gameplay needs. The television supports AirPlay, allowing for easy content streaming from Apple devices, and enables connection to various Bluetooth devices, such as mice or headphones, increasing its versatility. The only downside that can be considered is the lack of support for USB recording and the fact that the Q80D unfortunately does not support the DTS audio format. This means that if we have content encoded in this format, the device will not be able to correctly playback the audio track. This could pose a problem for those using Blu-ray discs or multimedia files that often use DTS to provide high-quality surround sound. To achieve full audio experiences, it may be necessary to use an external player or soundbar that supports this format.

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.

The built-in player in the Samsung Q80D television is definitely one of its strong points. It handles almost all video and audio files we used in our tests exceptionally well. The only exceptions are the Dolby Vision format, which is not surprising, and less popular codecs. Additionally, it is worth noting the support for Polish characters and the ability to customise font colours. On the downside, the television performs somewhat worse with photo formats, as it only supports JPEG from the popular options, lacking support for formats like PNG or Apple HEIC.

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 Samsung Q80D television is equipped with a decent audio system boasting 40W power in a 2.2 configuration, providing quite good sound experiences. This system supports all popular Dolby codecs, allowing for the use of advanced audio formats while watching films or playing games. However, it is worth noting one drawback: the television does not support DTS functionality. Nonetheless, this lack can be circumvented by connecting an external audio system, which can significantly enhance sound quality and provide a more immersive audio experience. Additionally, Samsung offers a wide portfolio of soundbars that can be integrated with the television, as well as the Q-Symphony system, which allows for the synchronisation of sound between the television and the soundbar.

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.
