Compare: Samsung QLED Q70D / Q74D / Q77D vs Samsung QLED Q80D

Samsung Q70D performed in the test exactly as it should for its price range – very competently. The strongest aspects of the television are certainly its performance when using a console and colour reproduction after the calibration process. The former will undoubtedly catch the attention of gamers with a range of conveniences that Samsung Q70D can offer, and there are quite a few, including that which is almost exclusive to the manufacturer's units – the ability to smooth out gameplay while still maintaining reasonable input lag, allowing titles running at 30 fps to perform like those at native 60 frames per second. In the context of gaming, one cannot forget the well-implemented HGIG mode, which, when set correctly, is on par with games using Dolby Vision. We must also acknowledge the easy pairing of the television with the Canal+ decoder, which is not such an obvious advantage, but we know that many people experience issues with this. Staying on the topic of television, it must be noted that the Samsung Q70D offers very good brightness in SDR content for its price range, making daytime viewing more than comfortable. A downside for the tested television is the lack of Dolby Vision, which would have significantly enhanced performance at the maximum brightness of the Samsung Q70D. The device's construction flaws should not be overlooked, as they may (though not necessarily) lead to light bleed that can be noticed in dark situations during dimly lit scenes. What cannot be taken away from the Samsung Q70D is the fact that it features one of the better motion smoothers in its price bracket, which works excellently for sports events or fast-paced action scenes. The system responsible for the television's operation runs very smoothly, and the only thing we can criticise it for is the absence of the Tidal app. In summary, the Samsung Q70D represents a good continuation of the manufacturer's seventh series, which year after year is gaining – firstly, in quality, and secondly, in popularity.

Samsung Q80D is a very versatile television. It’s definitely a piece of equipment that can easily adapt to the needs of both gamers and those looking for a device for everyday viewing. As for the former - namely gamers. Thanks to HDMI 2.1 support, a 120 Hz refresh rate, and low input lag, it makes playing on console or PC pure pleasure. Additionally, the Game Bar feature allows for quick adjustments without the need to exit the game – a small thing, but it makes a difference. It’s also worth mentioning a fantastic feature in the form of an efficient motion smoother that works well in games. It gives the impression that playing on such a television adds a few FPS, thus providing an advantage in the game. During everyday use, the Q80D performs very well too. The Tizen system offers access to popular apps such as Netflix, Prime Video, and Disney+, so nothing is lacking here. The high brightness of the screen ensures that the television performs very well even in well-lit rooms. A nice and interesting addition is the solar remote, which not only does not require battery replacements but also allows control of 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 fantastic, and the contrast and black level thanks to FALD technology (full array local dimming) impressed us greatly, considering the television's segment. Thanks to the VA panel enhanced with quantum dots (QLED), the colours on the Q80D can look truly excellent. Watching movies or series in the evening is a real pleasure – especially if we care about good details. However, there are little things that might be bothersome. The lack of a recording feature is a certain 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 with the fact that at the cost of great blacks, the Q80D simply performs average when looked at from the side. Nevertheless, the Samsung Q80D is a great television that performs well in every situation. It offers excellent picture quality, many useful features, and solid build quality for its price range. A few minor shortcomings, however, do not take away its charm, as overall it’s a model that will comfortably meet the expectations of most users – both those who game on consoles and those who simply enjoy evening screenings with good visuals.

Samsung Q70D and its related models, such as Q77D and Q74D, use a VA panel, which should inherently provide decent contrast. Typically, it is several times higher than that of IPS/ADS screens that do not come equipped with an advanced local dimming system. As you can see, contrast results are quite varied, which is caused by the unevenness of the panel. Therefore, we might sometimes get good contrast, and other times it can be significantly worsened, but generally, it remains fairly consistent, aside from light bleed. Let’s take a look at the film scenes we prepared from "Oblivion" and "Revenant." As we can see, in the first one, the lights are well separated, which is a positive phenomenon, as the visibility of details in bright areas in further tests should be equally good. What stands out the most here is the unusual oversharpening of the smoke visible under the light and the navy black in the background. In the frame from the second film, the first thing that stands out is the unevenness of the backlighting of our piece. This was significant and strongly affected the perceived image. Nonetheless, the details in the film were well visible.

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 have better viewing angles but poorer contrast. For the 55" model, the television has 100 local dimming zones, and it should be noted that this number may vary depending on the screen size. Thanks to local dimming, blacks look good, but it's worth mentioning that the algorithm of this technology, combined with a limited number of zones, can sometimes go a bit "haywire." Bright objects can be dimmed to achieve better blacks. During testing in a scene from the film Oblivion, the lights merged into one blot, regardless of the dimming settings, showing the limitations of this technology. In the movie Sicario 2, large dimming zones were particularly noticeable, for example, with small helicopter lights, indicating how large the areas controlled by a single dimming zone are. Despite these imperfections, the local dimming technology still offers significantly better picture 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.

The brightness that the Samsung Q70D can offer is at a rather average level, although it cannot be said that the HDR effect will not be noticeable. Any brightness above 400 nits allows for a clear distinction between SDR and HDR content. As was the case in the paragraph about contrast and black levels, we can also observe here that the first scene, featuring a bright sunny sky and a darker foreground, has the lowest luminance of those measured. The result, which can be considered very good for this price range and display class, is that one. In a scene where we see a large light source filling a significant portion of the frame, the brightness of the TV is at its highest, reaching nearly 500 nits. However, it is worth noting the rather low coverage of the wide DCI-P3 colour gamut, which sometimes results in noticeable shortcomings in the colour reproduction. Additionally, users can enjoy rich colours and high precision in rendering shades, making movie screenings a unique experience. It is also worth mentioning that the Q70D Samsung panel performs excellently in eliminating blur during dynamic action scenes, which enhances the viewing comfort of sports broadcasts or games.

In the context of HDR, the Samsung Q80D television, as expected, achieves very positive brightness results in the tested movie scenes, where the frame is filled with light, reaching values from 600 to 900 nits, allowing for a great juiciness of the image. Such results enable 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., the 4th test screen from the film Sicario 2), a noticeable drop in brightness is observed, which is caused by the large size of the dimming zones used here. This limitation, combined with the dimming algorithm, affects how the television handles small bright elements on a dark background. At that point, we may experience an undesired lack of brightness, and the HDR effect resembles that of SDR.

The best factory mode in Samsung Q70D is "Filmmaker," and it was this mode that we used during all our tests. Before the calibration process, it had several flaws that effectively hindered the presentation of the director's intentions. In both SDR and HDR material, the white balance was dominated by red and green colours. As a result, there was a characteristic yellow tint on the image, which caused whites to appear yellowed and skin tones to be noticeably too warm. The reduced gamma in standard colour palette materials caused a significant drop in contrast, which was already not the highest. This led to the highlighting of details in the blacks, but also to clipping in brighter scenes. In this case, the EOTF curve proved to be much better and only brightened those scenes with quite low luminance. This was clearly visible in the section where we measured the maximum brightness of the television in HDR materials. At that time, a shot from the film "Billy Lynn" appeared unnaturally bright and lacking depth.

In "Filmmaker" mode, which is the best choice right out of the box, the Samsung Q80D television shows solid colour reproduction. For SDR content, a noticeable drop at the start of the gamma curve suggests that details in dark scenes may be less clear, affecting the overall viewing experience. Regarding white balance in SDR content, while generally correct, significant drops in blue at screen coverage above 70% can result in less natural shades in both bright and dark scenes. Users may notice that some blue elements in the image may appear less vibrant, and the overall colour will have a warmer hue.

In HDR content, the EOTF curve being above the reference line for most of the time indicates that the television may struggle to accurately reproduce brightness and details in the brighter parts of the image, which can be detrimental for the viewer. It is also worth noting the significant drop at the start of this chart, indicating that the television has difficulty reproducing brightness in the darker parts of the image, as seen in the contrast and black test, where several scenes were unable to show the full capabilities of the television’s brightness. In terms of its white balance, the initially good performance on the graph is promising, but the steep decline in red, coupled with a significant increase in blue, can lead to inaccuracies in reproducing some skin tones and other key colours. This phenomenon may be noticeable to viewers in scenes where colour details are crucial.

Fortunately, Samsung provides a wide range of calibration tools in all its TVs, including 2- and 20-point grey scale adjustments and advanced CMS. As a result, we were able to significantly improve the quality of SDR and HDR content. The vast majority of errors have been corrected, and the image that the Samsung Q70D now delivers is definitely much closer to the reference. Higher deltaE errors in wide dynamic range content primarily result from the display's insufficient luminance.

The movie mode after calibration looks significantly better than the one you see right 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 (Color Management System). Both in HDR and SDR mode, white balance has improved significantly, although there are slight errors at the end of the graph for HDR content. 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 on the television appears to be at an ideal level at first glance. However, when we dig a bit deeper and enable the EOTF graph while watching films, we may notice that all the lines of the curve are above the reference line. You could even say that the television is "cheating" when playing film material. Such a situation, where the EOTF curve is above the reference line, causes the screen – although it may appear brighter, which some users might find appealing – to 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.

Considering how important lighting is in films and series, the overlapping structures and fluidity of tonal transitions constitute an extremely significant element in assessing image quality. The colour grading on the tested television is at quite a decent level. It cannot be said that it is outstanding, but it is not bad either. We assess it as acceptable. Brighter scenes perform best here, demonstrating the least amount of choppiness. In scenes recorded in darker settings, slight shortcomings in grading can already be noticeable, although it is not an issue that would cause discomfort while watching. This may be disturbed by the leaking backlight, which is clearly visible in the last image.

The tonal gradation on the Samsung Q80D television is excellent and can be considered one of its strong points. Even in the most demanding scenes from the films we tested, it performs superbly. Any potential issues with smoothing transitions in colours are minimal and subtle. The average viewer is unlikely to notice them, which translates to an overall positive visual experience in everyday use.

The function responsible for improving gradation is named "Noise Reduction" in the menu. As we have confirmed, it is worth enabling as it has a beneficial impact on tonal transitions. More importantly, it does not negatively affect film grain or fine details, which sometimes the competition "offers" us.

The image scaling on Samsung Q70D should be rated as average. The manufacturer does not aim to artificially sharpen the image, but rather to keep it naturally softened.

Samsung Q80D performs very well with low-quality materials. The noise reduction works on the principle of gentle gradation, making it very effective in smoothing out unwanted image disturbances. Unfortunately, this same effectiveness also causes it to blur elements that shouldn't be smoothed, such as film grain. For those who prioritise a plastic, smooth image, this can be seen as a significant advantage, especially with lower-quality content.

In terms of image scaling, Samsung Q80D stands out positively in this aspect, significantly enhancing the viewing comfort. The TV handles the conversion of lower-resolution materials, improving their quality and details. For example, in the attached image featuring a model, there are no visible artefacts or excessive fraying of branches, which demonstrates advanced image processing technology.

Samsung Q70D is the first model in the manufacturer's portfolio with a 120Hz panel. As a result, its motion smoothing features are more advanced than those in lower-tier models. In the menu, we find three functions responsible for improving fluidity. They are "Blur Reduction," "Judder Reduction," and "Clear Motion (LED)." We'll discuss the third one later. The first function enhances sharpness in motion, while the second adjusts the level of smoothing. The smoothness enhancer in Samsung Q70D works satisfactorily, and each setting makes a noticeable difference. Therefore, those who dislike the characteristic stuttering of films or who passionately watch sports will be able to achieve their preferred level of smoothness. In the image, we present a setting with slight smoothing, without the soap opera effect.

The panel used in Samsung Q70D has a fairly good response time for this type of display. Of course, it won't deliver an image as sharp as a proverbial razor, but at this price point, it is a recommended choice for all kinds of sports.

The Samsung Q80D television stands out very positively in terms of motion fluidity and minimizing blur, mainly due to the 120Hz panel and above-average panel response time. Users have two options for adjusting fluidity: "Motion Smoothing," which allows for adjustments in a 10-step scale, and "Blur Reduction," particularly effective at higher refresh rates, improving the sharpness of fast-moving objects. In the UFO test, there is no blurring behind the moving object, and the image is not cloned forward, indicating the absence of an overshoot effect.

The tested television is equipped with four HDMI 2.1 ports. Interestingly, all of them have a bandwidth of 40 Gbps; however, during the testing process, we did not observe any negative effects associated with this situation. More importantly, Samsung Q70D supports all features stemming from the aforementioned standard. This news will surely delight all gamers, as it means that whether using a console or a PC, we can expect the highest possible comfort during gameplay. Given the standard absence of Dolby Vision HDR for this manufacturer, it is significant that the HGIG mode has been implemented correctly and there are no issues with setting up the calibration chessboard. We particularly note that Samsung is the only manufacturer to allow gaming with the smoothness enhancer switched on, without significant degradation. This means that titles running at 30 fps will be perceived like those with native 60 frames per second.

Samsung, as one of the first manufacturers, introduced the Game Bar to its televisions, which has since been consistently refined. It contains all the necessary information regarding gameplay parameters that we can change "on the fly".

In summary: Samsung Q70D will perform excellently both with consoles and with computers. All functions worked brilliantly, and there were no issues with them. The ability to enable the smoothness enhancer without significant increases in input lag is a true gamechanger.

The Samsung Q80D TV is a real 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 at 4K resolution. These features ensure smoothness and responsiveness of the image, which is a key aspect during dynamic gameplay. The TV also supports HGIG (HDR Gaming Interest Group), enabling optimal HDR content display in games. Additionally, it comes with a Game Bar, providing quick access to gaming settings. Users with Nvidia graphics cards will also be pleased with the implementation of G-Sync. This feature eliminates stuttering and screen tearing. The only downside is the lack of support for Dolby Vision, which may be disappointing for users looking for that HDR format. It's also worth mentioning that since 2022, thanks to the collaboration with Microsoft, Samsung TVs offer the Xbox Game Pass app, allowing for cloud gaming. This is an added bonus for gamers who want to take advantage of a wide library of games without needing a console.

Results of latency on the Samsung Q70D are at a high level, regardless of the signal or resolution. All gamers will certainly appreciate the manufacturer's efforts, which allow a game running in 4K 120 Hz with HDR to have only 7 ms of latency, which is practically unnoticeable even in online gaming. It's worth adding that lag with the motion smoother turned on roughly doubles, which still means very comfortable gaming in this case.

What more can I say, the input lag at this level is simply outstanding. 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.

After connecting the television to the computer and wishing to use it as a monitor, we can expect a low input lag of 13 ms, which is practically unnoticeable on the mouse-screen-eye line. Thanks to the correct implementation of chroma 4:4:4, the readability of fonts is at a high level, so you can confidently connect Samsung Q70D to your computer as a monitor and expect a comfortable experience with text.

The subpixel layout is BGR, which does not negatively affect the use of the television as a monitor. However, as operating systems are not adapted to this type of subpixel format, it may cause slightly less distinct contours. This is, however, something practically negligible, and only a handful of people may notice it.

Samsung Q80D performs well as a computer monitor. With support for chroma 4:4:4 (only works in "Game" mode), text on the screen is sharp and readable, which is very important for those who want to work on such a TV with text documents or spreadsheets. One of the biggest advantages of this model is its exceptionally low input lag in “PC” mode, which is only 9 ms. This is a reference-level result that ensures smoothness and responsiveness, which is crucial for both gamers and video editing professionals. The only thing we can nitpick is that there is a certain issue with font rendering 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 TV 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 text rendering on dark backgrounds. Nevertheless, Samsung Q80D is a very good choice as a PC monitor.

Due to the VA panel, the performance of Samsung Q70D in terms of viewing angles is its Achilles' heel. Even a slight shift off-axis leads to a significant loss of contrast and a substantial degradation of colours.

Samsung Q80D, equipped with a VA panel, unfortunately doesn't perform well with 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 TV from different spots in the room. However, the VA panel has its advantages. When we look directly at the screen, black is deep and well-saturated. Moreover, even at an angle, dark colours retain their depth, which is rare for this type of panel.

The satin finish of the panel in the Q70D allows for quite good performance in a well-lit room. It is worth noting that reflections do not spread beyond their source, and thus do not bleed onto the rest of the panel. We also commend the maximum brightness of the TV in SDR content, which is 450 nits, allowing for comfortable content consumption during the day.

The Samsung Q80D television stands out with very good brightness, averaging 550 nits, which is an impressive result, especially as it maintains this brightness across the entire surface of the screen. As a result, the picture is sharp and clearly visible even in bright rooms, which is a big plus when watching television during the day. However, despite the matte coating on the panel, the television struggles somewhat with glare suppression. In bright lighting conditions, unwanted reflections can occur, which may disrupt viewing comfort. This is particularly noticeable when there are light sources in the room that directly hit the screen.

The operation of Samsung Q70D is managed by the proprietary Tizen system. This is fairly well-known software, as the manufacturer has been developing it in their TVs for quite a long time. Its main advantage is smooth operation and a lack of significant stutters, which we can confirm through conducted tests. The biggest downside, however, is its closed nature. Although the app store is quite extensive, we are still dependent on the grace or displeasure of the manufacturer. Therefore, we will not be able to install missing items, even from a USB drive. A perfect example of this is this year's discontinuation of support for the Tidal app. On the other hand, a benefit, especially for Apple device users, is the implementation of AirPlay functionality, which allows for easy screen mirroring from a device to the TV. Fortunately, Samsung also provided the option to connect a keyboard and mouse for much quicker navigation through the TV menu. It’s worth mentioning that the manufacturer has thankfully included a remote that connects via Bluetooth this year, which often wasn't the case in the past. The Tizen system has one more advantage. It integrates very well with external devices, such as the NC+ decoder or soundbars. The connection process is very quick and does not require special skills.

In summary: The Tizen system is very efficiently functioning software, which is certainly a strong advantage of the TV. While more advanced users may complain about the lack of something like KODI, the rest will be satisfied.

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, navigating through apps and settings is quick and easy. Tizen supports a rich set of applications, including popular streaming services, allowing access to a wide range of entertainment content without the need for additional devices, and a new feature for 2024 is support for the Polish language. It's also worth mentioning the solar remote control, which is not only eco-friendly but also convenient for everyday use. The solar cell remote can easily control other devices such as home theatres, set-top boxes (e.g., Canal+), or gaming consoles, which is quite a challenge for other manufacturers. Returning to the console, Samsung Q80D offers several features that gamers may appreciate. Firstly, the television supports VRR (Variable Refresh Rate) technology, which enables smoother game display, eliminating issues like tearing and stuttering. Additionally, with low input lag, reactions in games are quick and precise. The Samsung Q80D is also equipped with a Game Bar feature, which allows quick access to key gaming settings without the need to exit the game. From this interface, we can check and adjust parameters like VRR, input lag, frames per second (FPS), as well as screen ratios and sound settings. This means gamers can continuously optimise their experience by adjusting settings according to their current gaming needs. The television supports AirPlay, allowing easy content sharing from Apple devices, and enables connection to various Bluetooth devices such as mice or headphones, increasing its versatility. The only downside is the lack of USB recording support and the fact that the Q80D unfortunately does not support the DTS sound format. This means that if we have content encoded in this format, the device will not be able to properly play back the audio track. This could pose a problem for those using Blu-ray discs or media files that often utilise DTS to provide high-quality surround sound. To achieve complete audio experiences, it may be necessary to use an external player or soundbar that supports this format.

The built-in player Samsung Q70D is a significant advantage. It handled nearly all video and audio files prepared for the testing process exceptionally well. The only exceptions in this regard are of course 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 change font colours as a positive aspect. However, it struggles more with photo formats, as it only supports JPEG among the popular ones. There's definitely a lack of formats like PNG or Apple's HEIC here.

The built-in player in the Samsung Q80D television is definitely one of its strong points. It handles almost all video and audio files that we tested exceptionally well. The only exceptions are the Dolby Vision format, which is not surprising, and less common codecs. On the plus side, it supports Polish characters and offers the ability to customise font colours. On the downside, the TV struggles a bit with photo formats, as it only supports JPEG among the popular ones, while lacking support for formats like PNG or Apple HEIC.

The built-in audio system Samsung Q70D, due to its slim design, is not among the most outstanding. Overall, it's fairly balanced, although we wouldn't recommend cranking up the volume to levels higher than 2/4 of the scale. However, if we have a home theatre system, there is a range of codecs available, and we can enjoy the presence of the most important ones, namely DTS-HD Master Audio and Dolby Atmos.

The Samsung Q80D television is equipped with a decent audio system with a power of 40W 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 during movie watching or gaming. However, it is worth noting one drawback: the television does not support DTS functionality. Nonetheless, the lack of this feature can be bypassed by connecting an external audio system, which can significantly improve 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 sound synchronization between the television and soundbar.
