Our verdict

Samsung offers two top models with a 4K resolution when it comes to MiniLED technology. In this test, we took a closer look at the not so "fancy" QN95D and QN90D, which we can also find under the name QN92D. Samsung proudly calls its MiniLED televisions the NeoQLED series. Thanks to this technology, the TV offers excellent contrast and high brightness, making movie watching an experience reminiscent of true cinema. During everyday use, the Tizen system performed excellently. It is fast, intuitive, and allows seamless switching between applications. We also appreciated how well the TV handles lower quality materials – traditional TV or older films looked better than we expected, and the advanced image processing algorithms did their job. This is a TV that can really enhance the viewing experience of content that isn't always in high resolution. The solar remote was a pleasant surprise for us. Although minimalist and with a small number of buttons, it turned out to be very practical – it allowed us to control not just the TV, but also other devices, like the decoder (Canal+) or soundbar. This meant we could reduce the number of remotes on the table, which immediately improved usability. Plus, solar charging – a simple idea that eliminates the need for battery replacements and aligns with eco-friendly trends. As for the picture in different conditions, the TV performs well in both bright and dark rooms. The high brightness and numerous dimming zones handle most content, although sometimes in contrasting scenes a halo effect is noticeable. The colours, however, are vibrant and natural, and the QLED coating gives them intensity. For even better results, we decided on calibration – after which the picture looked even more detailed and natural, which only confirmed our belief that QN92/QN90 is an excellent choice. And what about motion on the screen? It is absolutely fluid. The 144 Hz panel does an excellent job with dynamic scenes – fast actions, sports, games – everything looks natural and without blurring. We particularly appreciated the Auto Motion Plus Game feature, which makes games running at 30 frames look smoother, resembling 45 frames, and at 60 Hz, motion becomes even more natural, as if operating at 90 Hz. For gamers, this is a huge plus, especially since low input lag and features like the game bar further enhance the gaming experience. This is a TV that performs well in any situation – from evening screenings to gaming marathons. QN92D is a practical, well-designed TV that offers a picture quality that's really hard to ignore. An ideal choice for those looking for something more than just a regular screen for everyday content.

LG C4 is a television that will likely have no competition in its price range for many users. Thanks to the wide options for purchase, it will appeal to those looking for a TV strictly for movies and series, as well as for gaming. The advanced WebOS system and a remote that works like a mouse will certainly make everyday use much easier and ensure that we will likely stick with this brand for a much longer time. The OLED panel implemented by the manufacturer, resulting from over 10 years of history, shows that it has not yet said its last word. Brightness results in HDR material are very solid and can display an incredibly dynamic and deep image. Here, it’s worth mentioning the excellently implemented dynamic tone mapping feature, which makes HDR10 images look almost as good as Dolby Vision. And if we’re talking about fidelity to artistic vision, we can't forget about how calibratable LG TVs are, allowing for a great deal of freedom for the calibrator and classic calibration for home users, as well as 3D LUT for professionals. However, if we are looking for a gaming TV, then the LG C4, like most of the manufacturer’s OLED TVs, will be the ideal choice. With the implementation of HDMI 2.1 ports and the full use of their potential, we can enjoy extremely smooth gameplay with all the benefits, such as VRR, ALLM, FreeSync, or G-Sync. Of course, the panel, which has a maximum refresh rate of 144 Hz and an advanced smoothing technology, will also allow for very smooth and sharp images during broadcasts of various sporting events. It’s hard not to give a high rating to LG OLED C4, as it's difficult to find a TV in a similar price range with such advanced features among the competition.

Halo effect and black detail visibility:

Samsung QN92D is one of the top models of NeoQLED 4K (mini LED) from the Korean manufacturer for 2024. Although it does not offer as many dimming zones as its more refined sibling Samsung QN92D, the number of 504 dimming zones in the 55-inch version is still impressive. The VA panel works well with this solution, providing excellent results in terms of contrast. The contrast in Samsung QN92D is outstanding for a non-OLED television. Even in difficult scenes, like those from the movies "Oblivion" or "Arrival," the contrast is nearly infinite and can compete with the best televisions in the OLED segment, which is quite unusual among LED-lit televisions. However, mini LED diodes have their limitations compared to organic panels, which can lead to some issues. For example, on the last test screen from Pioneer, the television has significant difficulties. This may be due to a very aggressive dimming algorithm, which sometimes causes the mini LED diodes to struggle with what to do – whether to illuminate certain elements or maintain the blacks. Despite these drawbacks, Samsung QN92D is one of the best LCD televisions in terms of contrast and blacks.

LG OLED C4, as the name suggests, uses an organic panel of its own production. This series definitely belongs to one of the most recognisable on the market. Over 10 years of experience in building self-emissive panels has allowed for the refinement of each subsequent design, with the models from the 2024 range being the quintessence of this process. Of course, the use of this type of screen enables the achievement of flawless contrast and blacks, allowing viewers to immerse themselves in the world created by the director. This is possible thanks to the OLED panel, characterised by the absence of conventional backlighting, which instead allows current to pass through organic pixels. This permits super-accurate image control, thereby eliminating issues such as dimming of delicate fine details or the halo/blooming effect. Looking at both of our test scenes, we can notice two things: perfect light separation and a plethora of details in the movie "Sicario 2".

Samsung Neo QLED QN90D / QN92D

During synthetic tests, Samsung QN92D showed its incredible capabilities in terms of brightness. The charts clearly indicate that the television can achieve an impressive 2000 nits, giving it a solid power base to compete with the best models on the market. Such a result places it at the forefront, especially in the context of displaying HDR content, where brightness plays a key role. However, what happens when we move the tests to real film scenes? In favourable conditions, such as the first scene from the movie Life of Pi or the last scene, where the image is completely flooded with light, Samsung QN92D can achieve almost laboratory results, impressing with its brightness. The situation looks different when small, bright objects appear on a dark background, as in the fourth scene from the movie Sicario. In such cases, the television doesn't perform as well – brightness drops several times, and maximum values in the best conditions are around 600 NITS. Similar to contrast, these limitations arise from the use of an aggressive local dimming algorithm. This algorithm aims to reduce the 'halo' effect around bright objects on a dark background, but often at the expense of overall brightness. As a result, while the television performs well in bright scenes, its ability to display full brightness is limited when it comes to small, vivid elements.

The results of HDR materials are definitely among the better ones. Practically every film significantly exceeds the 700 nits barrier, which allows for a very realistic image. Of course, none of them surpasses the magical thousand, however, the combination of such results along with unlimited contrast and black effectively boosts the visual outcome. The last of the scenes, featuring a fullscreen sun burst, is indeed less bright than the others, although it still represents a respectable level. It's also worth mentioning the excellent coverage of the DCI-P3 colour palette, which will enable the achievement of exceptionally vivid colours.

Factory color reproduction

The best mode that reproduces colours best on the Samsung QN92D has consistently been the Filmmaker mode for years. While it generally offers decent colour quality, it is not free from significant issues. Let's start with the analysis of HD/SDR image quality. The biggest challenge here is the white balance – the graphs show considerable instability, with a clear dominance of red making the image too warm. This distortion causes hues to be unnaturally shifted towards warmer tones, which can negatively affect the perception of materials with natural colours. Contrast, based on the gamma chart, although not the worst, remains far from ideal, impacting the overall image quality, especially in darker scenes.

This issue also persists with 4K materials, such as series or films of higher quality. In this case, the white balance also turns out to be faulty, with noticeable deficiencies in blue and red colour, leading to tonal shifts. Tests using the Colour Checker tool confirm these problems – all colours tend to skew towards yellow shades, further distorting the natural appearance of the image. Although the Filmmaker mode is one of the best available modes for watching cinematic content, it still requires improvements, especially in terms of colour accuracy and white balance.

The best factory mode implemented in the tested television was "Filmmaker". That was the one we used during all tests. This mode, in terms of colour reproduction, turned out to be quite decent, although other flaws effectively detracted from the enjoyment of the viewing experience. Starting with the most basic one, which is white balance, it was easy to notice that this was marked by a dominance of red, which completely altered the characteristics of the picture. We could see a strong yellowing of the whites and a shift of all colours to warmer tones. The gamma, which is a graph as equally important, if not more so, was quite severely reduced, resulting in a significant drop in contrast, except for the start of the graph, where the television insidiously lost details. That’s all regarding SDR materials. Looking closely at films with a wide dynamic range, we can observe exactly the same phenomenon of white balance yellowing as in films with a standard colour palette. The EOTF curve, which replaces the gamma chart for us, is practically perfect and cannot be faulted.

Color reproduction after calibration

8.7/10

9.5/10

After calibration, the Filmmaker mode on the Samsung QN92D television shows significant improvement, particularly in the SDR content range. The white balance has been greatly enhanced – the previous colour misalignment and dominance of red have been eliminated, resulting in a more natural colour reproduction. In terms of brightness, although the gamma chart did not require significant adjustments, it has been stabilised, which affects the overall picture quality.

Regarding high-quality materials, the white balance has also improved in this case. However, it is worth noting the contrast. The EOTF curve, which illustrates the values in this area, appears correct at first glance. However, upon closer inspection, the television struggles to maintain appropriate contrast in film materials. The EOTF curve reveals some discrepancies, suggesting that despite the progress, there are still areas that require improvement in this aspect. The television continues to strive for excellence in contrast reproduction. A strength of this television is the saturation of colours. Skin tones are rendered very well, and although some colours may be slightly oversaturated, the overall effect looks really attractive – the colours appear rich and vibrant.

Despite some shortcomings in contrast, after calibration, the Filmmaker mode on the Samsung QN92D offers excellent image quality, with natural colour reproduction, making it a great choice for watching movies.

As we mentioned earlier, LG televisions are equipped with advanced tools for carrying out the calibration process. We used them to model the picture in line with what the director envisioned. And without modesty, we must admit that we achieved this phenomenally. Both SDR and HDR materials present a level that clearly indicates this is how a film should look. It's worth taking a look at the colour errors on the "ColorChecker" palette, where practically none of them exceed "1", except for two samples.

Smoothness of tonal transitions

9/10

7.1/10

The fluidity of tonal transitions on the Samsung QN92D TV is excellent, making the image look exceptionally natural, without visible disturbances. In scenes with complex colour gradations, the TV performs brilliantly, providing smooth and uniform transitions. Competing OLED TVs in a similar price range could successfully take a cue from this, as the Samsung QN92D offers quality that places it on par with models equipped with QD-OLED panels.

The fluidity of tonal transitions in LG televisions has always been a rather sensitive issue, as the manufacturer, despite impeccable performance in other areas, has almost always struggled to get this right. The evaluation results for the fluidity of tonal transitions in the tested television were quite good, with issues mainly visible in darker scenes, such as the last two scenes. Interestingly, this is a significantly better result than the highest model from the manufacturer, namely the LG G4.

Let's check how the Samsung QN92D TV performs with tonal transitions in very poor quality materials. The noise reduction feature shows good effectiveness, improving the fluidity of tonal transitions even in difficult conditions. However, it should be noted that, similar to other Samsung TVs, the effectiveness of this feature can lead to the removal of desirable elements, such as film grain, which can sometimes affect the authenticity of the image.

When it comes to digital processing, the Samsung QN92D TV also performs excellently. During tests, the image looked very good, with the model presented in a natural and correct way. Details, such as branches in the background, were reproduced with great precision, highlighting the TV's ability to enhance the quality of low-resolution materials.

Once again, we will take a look at the feature responsible for gentle gradation, but we will also address the one that aims to enhance the quality of lower-quality materials. The default smoothing of tonal transitions, as we could see, was not the worst, but it can be improved further. The function has a slider that allows us to adjust its intensity. We recommend using the former, as it produces very good results and does not blur important details.

Image scaling on LG C4 is quite good, however, it cannot be said to be without flaws. The image is slightly sharper by default, although not in a very noticeable way. While jagged edges of trees can be seen, it is not a major issue when compared to other manufacturers.

The Samsung QN92D television is equipped with a 144 Hz panel; however, when watching content using the smoothness feature, the maximum refresh rate is 120 Hz. As a result, both gamers and sports enthusiasts will be satisfied with the picture quality. It’s also worth mentioning the available options for image enhancement, such as the "motion blur and judder reduction" feature, which allows users to adjust smoothness to their individual preferences on a 10-point scale. Motion blur reduction increases the sharpness of fast-moving objects, while judder reduction smooths out motion, eliminating the "stutter" effect. With these advanced settings, one can achieve optimal visual experiences, making the Samsung QN92D perfect for both dynamic scenes and intense gaming.

In terms of motion blur, the television performs really well, and it’s hard to pick faults. The only note we might have is a slight overshoot effect noticeable on dark backgrounds during our test with "Ufoludkiem." Nevertheless, thanks to the advanced smoothness settings, the Samsung QN92D excels in both dynamic scenes and intense gaming.

The maximum refresh rate we can set on the LG G4 is 144 Hz. Naturally, this is only possible when connecting the TV to a very powerful PC. Otherwise, we will operate at a maximum refresh rate of 120 Hz, which is recommended if we primarily want to watch sports or content with a lot of motion dynamics. For those who require high fluidity of the image, the manufacturer has implemented a multi-level motion smoother called "TrueMotion". It has been divided into two separate sliders that adjust the sharpness of moving images (De-Blur) and judder (De-Judder). Both sliders can be set in the range of 0 to 10, with each degree affecting the level of smoothing, allowing everyone to find their sweet spot.

The panel of the LG OLED C4 features an average response time of less than 1 ms (which directly results from our measurements), enabling the achievement of an extremely clear image, unattainable for LCD TVs, which can have response times of up to several milliseconds. This is clearly evident in the images from the "UFO Test," which show no trailing blur behind the object.

The television Samsung QN92/QN90 is an excellent choice for avid gamers, deserving of the highest recommendations. This model offers practically all the features available on the market in terms of gaming, making gameplay even more exciting. One of the key differentiators is the 120 Hz panel, which ensures exceptional motion smoothness, crucial during dynamic action games. The television also boasts low input lag, guaranteeing instant reactions to player commands. Additionally, technologies such as VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode) adjust the refresh rate and automatically switch the television to game mode, translating to even better gaming experiences. Another advantage is the Xbox app, which allows gaming of favourite titles directly on the television, eliminating the need for a console. This is a typical feature of Samsung televisions, making them exceptional in the gaming world.

Auto Motion Plus Game is a feature that really deserves praise for Samsung. It is a motion smoother that works wonderfully in games, creating the impression of a higher frame rate – a 30 frames per second image looks like 45, and 60 Hz becomes close to 90 Hz. Importantly, this feature does not introduce significant lag (input lag does not exceed 25 ms), so it does not negatively affect gameplay comfort, unlike many other smoothers available on the market. This allows gamers to enjoy a much smoother image without compromising responsiveness.

We can now say that LG C4, like practically every OLED television from the manufacturer, is exceptionally good in terms of cooperation with consoles and PCs. Thanks to the implementation of four full-bandwidth HDMI 2.1 ports at 48 Gbps, the manufacturer has embedded all the features that enhance gaming comfort, including simultaneous support for FreeSync and G-Sync technologies. With such a tandem, players with graphics cards from AMD or nVidia can safely choose C4. However, what should please gamers demanding the highest possible quality the most is the simultaneous implementation of HDR Dolby Vision and HGIG mode. The former is particularly important as it operates with extremely low input lag in all settings.

A standard feature in televisions from the Korean manufacturer is also the implementation of GameBar, allowing for quick adjustments of settings "on the fly," without the need to exit the game. It also allows for image adjustments for people with visual impairments, which is an incredibly nice touch. Another important piece of information is that when VRR technology is enabled, we won’t experience a drop in contrast. This is, of course, due to the design of the panel and the absence of conventional backlighting. It is, however, normal for shades of grey to flicker slightly, although this is a characteristic feature of this function regardless of the manufacturer and television.

In summary: LG C4, just like all the manufacturer's OLEDs equipped with high-refresh-rate panels and HDMI 2.1 connections, creates a harmonious whole with consoles. In practice, it is a complete television, and if we expect the highest possible efficiency in gaming, C4 will be an ideal choice.

The input lag category is crucial for gamers, and the Samsung QN90D performs exceptionally well in this aspect. Input lag values below 13 ms are impressive, meaning that the delay between pressing a button on the controller and the reaction on the screen is minimal. Such a low value allows for smooth and responsive gaming experiences, which will certainly please both casual gamers and professionals for whom every millisecond of reaction time matters. This makes the Samsung QN92D an excellent choice for those who value precision and speed in gameplay.

The latency time of LG C4 is remarkably low in every scenario. Even the most avid gamers will surely appreciate the very low input lag at demanding 4K 120 Hz settings with HDR, which is only 5 ms. It's also worth noting that the lag at these same settings, but with Dolby Vision HDR enabled, remains unchanged, which is not so obvious with the competition. Therefore, it deserves the highest rating and recommendation.

The television stands out with its high performance, supporting chroma 4:4:4 and offering exceptionally low input lag. These features allow users to enjoy fluidity and responsiveness, making it an excellent choice for office work and everyday applications. However, one noticeable drawback is the poor visibility of horizontal lines on dark backgrounds. On the test screen, letters on the right side appear more like vertical lines, which can be frustrating for some users. Nonetheless, the television generally works well with a computer, providing comfort in carrying out daily tasks. It’s also worth mentioning in this paragraph the "Remote PC" feature; thanks to Microsoft’s collaboration with the Korean giant, we can seamlessly pair Windows PCs and use Office 360 apps.

LG C4 combined with a PC works wonderfully, thanks to its very low latency of just 13.5 ms, which is practically instantaneous feedback between the mouse, eye, and screen. An extremely important aspect when working on a screen is the readability of text, which in the case of the tested TV is very good. However, it is worth noting that to achieve sharp fonts, you need to enable the passthrough option in the settings.

The RWBG pixel layout does not significantly affect the display of fonts or letters, which is a significant advantage over Samsung's QD-OLED panels. Users of both Windows-based PCs and macOS will surely be pleased with their experience on the tested TV screen.

In the case of TVs with VA panels, you can usually expect limited viewing angles, however Samsung QN90D surprises in this category. Thanks to the applied coating that widens the viewing angles, the TV offers really good performance, which is rarely seen in devices with this type of panels. Although VA panels are typically not the best in this regard, in this model the image remains clear and saturated even when viewed from the side, making it a great choice for larger rooms and group viewing.

The undisputed advantage of OLED panels is their efficiency in the context of group viewing, meaning from various angles. LG C4 maintains very good contrast, colour saturation, and fidelity. Although this isn't a result of organic TVs supported by MLA technology, it's fair to say that anyone who purchased the device was satisfied with the results obtained. However, it should be noted that at sharp angles a slight greenish tint can be observed. This is a characteristic feature of WRGB panels from LG, without the aforementioned micro-lens technology, and unfortunately, there's nothing that can be done about it.

The television performs well in bright rooms due to its high brightness, especially when watching standard television. A constant brightness level of 600 nits ensures excellent visibility even in intense daylight. Unfortunately, despite the use of a satin finish, handling reflections is average, which can affect viewing comfort. An additional downside is the matrix that improves viewing angles, which causes reflections of sunlight to spread vertically, potentially further reducing viewing comfort in a bright environment.

The maximum brightness of the television in SDR materials is 367 nits. For an OLED television, this is a very good result and allows for quite comfortable viewing during the day. It's worth noting two things. Thanks to the glossy coating of the panel, the light reflections are well held in place and do not spill over the rest of the panel. The second issue is the brightness of the screen when fully filled with white, oscillating around 220 nits, which is a remarkable result, as until recently, OLED televisions in this category could only boast brightness half as much. As a result, the conditions for watching, for example, winter sports will be very good.

The Samsung QN92D television features a modern Tizen operating system, which offers users an intuitive and visually appealing environment. Tizen ensures smooth and fast navigation through applications, significantly enhancing the comfort of using the television. With an extensive ecosystem, users can easily connect the QN92D to other devices. The television supports many features that make everyday use easier, such as controlling set-top boxes with the remote, eliminating the need for multiple remotes. With AirPlay functionality, Apple device users can effortlessly stream multimedia from their iPhone. Additionally, there is a remote PC feature that allows users to access their computer on a large screen, as well as the Office 365 application, making the QN92D an ideal solution for both work and entertainment.

Furthermore, like many Samsung televisions, the QN92D offers Ambient Mode, which allows users to customise the appearance of the television to blend in with its surroundings. Users can display a variety of images or information, turning the television into an elegant part of the interior decor, even when not in use. Speaking of decor, it’s certainly worth mentioning the device's appearance. It is really very slim, around 2cm at its thickest point, which is impressive. The metal frame definitely gives the impression of a premium device, and the stand included in the box is sturdy.

However, for those using traditional television, the QN92D may prove to be a bit disappointing, as there is no television programme recording function available in the Polish market. Nevertheless, the television offers a Picture-in-Picture (PiP) feature that allows for simultaneous viewing of two programmes at the same time. The Samsung QN92D is a television with rich functionality that caters to both gaming enthusiasts and multimedia users, and it aesthetically fits into modern interiors.

LG uses the well-known proprietary WebOS system that has been around for many years. The system offers virtually all the major apps, and the few that are missing can be counted on one hand, such as CDA or KODI. It's also worth noting that the modern web browser and the remote with a built-in mouse allow for convenient access to streaming services in this way, if there isn't a built-in app.

WebOS also features a highly praised ability to perform operations using a cursor that appears when the remote is moved. The convenience of this function is invaluable when entering queries or passwords for portals. WebOS, like most systems, also supports features such as screen mirroring, AirPlay, voice searching in Polish, and the ability to connect headphones via Bluetooth. On a more practical note, WebOS allows simultaneous use of headphones and the television speaker, which will certainly be a significant help for those with hearing impairments. One of the more interesting features, particularly appreciated by sports fans, is the ability to turn on an alert for an upcoming match, ensuring that we never miss a broadcast. The home panel also deserves praise, allowing for control of all smart devices connected to the home network. For example, the end of a wash cycle will be signalled by a notification in the top right corner.

In summary, the WebOS system, although less known and with certain limitations compared to Android TV, offers stable and quick performance and supports most functions that users may need. It is a solid solution for those looking for a simple and effective operating system in their television.

The built-in player in QN90D should satisfy a large portion of users. It will easily handle most popular video and audio formats. However, more demanding users may notice some shortcomings – it is not possible to play photos in HEIC format, which is popular on Apple devices, as well as several other, less common photo formats.

The default file player on LG C4 handles all photo resolutions exceptionally well. It successfully plays videos recorded in practically all the most popular formats, including Dolby Vision. The only codec that the C4 won't play is H.266 VVC, although this is currently rather uncommon. It's a pity that subtitles in .txt format are not supported. Attention should be paid to the supported photo formats, of which there are only three: JPEG, PNG, and, importantly for Apple phone users - HEIC. However, the tested television cannot be faulted for a lack of variety in audio files, which can be played without a compatibility warning.

The television is equipped similarly to the QN95 with a speaker system featuring a 4.2.2 layout with a total power of 70W (the exception is the 50' variant with a 2.2 layout and the 43' with a 2.0 layout). Despite its very slim casing, the television sounds loud and clear, and the overall sound is well balanced. Points were deducted as per standard practice for every other Samsung model for the lack of support for the DTS format. It's also worth mentioning the proprietary Q-Symphony feature, which allows you to synchronise the sound of the television with a Samsung soundbar.

The audio system implemented in LG C4 is very well tuned, allowing us to experience strong bass as well as balanced mid and high tones. We can confidently say that in its price range, it's one of the better sounding televisions. However, we believe that those deciding to purchase the C4 will already have a dedicated audio set. The presence of DTS-HD Master Audio and Dolby Atmos codecs will also be significant.
