Compare: Samsung QLED Q70D / Q74D / Q77D vs LG QNED87T6B

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.

LG QNED87T is a television that definitely stands out. It's a bit unconventional – it doesn't try to forcefully compete with top OLED models, but it makes up for it with modern features and user-friendly operation. It's equipment that works great for those who value comfort and versatility. The 120 Hz panel, VRR, and ALLM make the television perform well with dynamic content. Games run smoothly, the picture is sharp, and the responses are quick. If we spend time on a console, we will appreciate the lack of lag or blurring. When watching sports, quick actions are clear, without stutters. On a daily basis, LG QNED87T is simply comfortable. WebOS operates intuitively, apps launch quickly, and the Magic Remote control significantly eases operation. Voice control saves time, especially when searching for movies or series. Features like USB recording or Bluetooth provide more options, enhancing its versatility. The IPS panel is a big advantage regarding viewing angles. No matter where we sit in the room, the picture looks good. It's a great solution in larger spaces where not everyone has a direct view of the screen. Older films or standard television from built-in tuners also present quite well – the improvement in the quality of lower resolution materials works surprisingly well. However, there are certain things that can be eye-catching. The contrast is simply terrible. In dark scenes, there are no details at all. In the evening, in a darkened room, this is very noticeable. During the day, these imperfections are less felt, so LG QNED87T performs better in well-lit places. LG QNED87T is a television that has its strengths. It handles dynamic materials well, is easy to use, and is excellent for bright rooms. It's not the ideal model for evening viewings in darkness, but in everyday use, it definitely stands out. It's a universal device worth considering when choosing a new television.

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.

In the category of black levels and contrast, the television LG QNED87T6B faces some challenges. Equipped with an IPS panel, it doesn't match the VA panel models in terms of performance in this area. Additionally, edge-lit dimming affects its poor results in this category. It's worth mentioning that the exception is the 50-inch variant, which has a VA panel and is not subject to this test.

Despite the manufacturer offering a dimming control option, the effects remain relatively weak. Test patterns show that the contrast is really poor, and in the test clip from the film "Sicario 2," it's clear to see how the television struggles with the backlighting, illuminating a large portion of the screen from below. This indicates that in more demanding scenes, the television has difficulties maintaining an appropriate level of contrast and black levels, which negatively impacts the overall visual experience.

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.

LG QNED87T6B delivers truly decent visual experiences when it comes to HDR. During our tests on test patterns, the television achieved brightness close to 500 nits, which is a satisfactory result and allows for good visibility of details in high dynamic range scenes. Support for basic HDR formats such as HDR10 and HLG ensures proper image quality. Unfortunately, the television does not support more advanced standards such as Dolby Vision or HDR10+, which are particularly important at this screen brightness. The lack of support for dynamic metadata means that in certain scenes, the television may struggle to fully reproduce details, especially in very bright areas – this is precisely when dynamic metadata could significantly improve image quality. Nevertheless, it is worth noting the excellent coverage of the wide DCI-P3 colour gamut, reaching as much as 96.4%. As a result, the colours displayed by the QNED87T6B model are more vivid and natural, enhancing the quality of 4K content viewed with a wide colour palette.

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.

The colour accuracy in the LG QNED, even in Filmmaker Mode, which is the best factory setting, is not without its flaws. The main issue is white balance – we noticed that the level of blue on the graph tends to drop. This results in a shift in colours towards yellow, making the image have a warmer tone than it should. This deviation affects the naturalness of colour reproduction, especially in scenes with a white or neutral background. The Color Checker test confirmed that some colours are distorted and deviate from reality. Such distortion can make film scenes appear less realistic, and details are presented in incorrect colours, negatively impacting the overall image quality.

Regarding contrast, the gamma graph analysis showed significant drops, while the optimal value should be 2.4. This means that the television may display darker parts of the image brighter in some scenes, which reduces their depth and dynamics. Additionally, on the EOTF curve, which is responsible for brightness reproduction, an unnatural drop was noted at the beginning. This phenomenon can result in less accuracy in reproducing dark scenes, which in turn affects the overall image quality. The television may not convey full black depth, causing more demanding scenes to lose realism and detail. As a result, viewers may notice that details in the darker parts of the image become less distinct.

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.

After calibration, the colours in SDR content look very good. The improved white balance translates to natural and harmonious shades in various scenes. Thanks to precise gamma tuning, details in shadows and bright areas of the image are accurately reproduced. The television performs excellently in everyday use, offering vibrant, well-balanced images and solid colour quality in HD. The biggest beneficiary here is also contrast. The gamma graph has been stripped of significant errors, giving the television a new dimension.

As for the white balance in 4K HDR, it has also been significantly improved. However, some errors still appear at the end of the graph. This may be due to the television's overly aggressive local dimming, which in some scenes affects the inaccurate reproduction of colours. It's difficult to talk about an improvement in brightness represented by the EOTF curve. The television, due to its construction limitations, has some drawbacks, and we can't overlook them. The Color Checker test confirms the issue with colour saturation – even though the television offers a wide colour palette, it fails to fully convey the director's intent.

Despite these shortcomings, the overall picture quality after calibration is significantly better than before. Adjustments in white balance and gamma tuning make the images more vivid and the colours closer to reality.

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 gradation in LG QNED is quite good, despite minor issues on the colourful dark sky. These small drawbacks do not detract from the fact that the gradation is one of the positive aspects of this model. Overall, the television handles smooth colour transitions well.

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.

When it comes to lower quality materials, the gradation looks really good. The feature called "Smooth Gradation" effectively smooths out the most problematic parts of the image, while not negatively affecting the film grain. For the best effect, it’s worth setting it to a low level. This solution significantly improves the quality of the displayed content, making the viewing of lower resolution materials more enjoyable and smoother.

In terms of digital processing, the image is displayed without cropping, known as overscan. Although slight fraying of the branches can be noticed against the model's background, everything looks very good. Users should be satisfied with the image quality when watching low-quality materials like standard television. The TV handles this task exceptionally well, providing a satisfying visual experience, even with lower quality content.

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 television provides decent smoothness when watching movies, thanks to the “Tru Motion” feature, which allows adjustment of motion smoothing from 0 to 10. De-Judder regulates motion smoothness, while De-Blur adjusts motion sharpness. Users have the option to choose between a traditional cinematic effect with subtle juddering motion (lower settings) and a smoother, theatrical image. Although the latter deviates slightly from the cinematic standard, it may be appealing to many viewers.

As for gamers and sports fans, the LG QNED87 television with a 120Hz panel will surely not disappoint. And with the use of an IPS panel, the response time is typically better than that of VA panels available at a similar price. This ensures smoother gameplay and dynamic experiences when watching sports events.

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.

LG QNED offers a range of features that make it an excellent choice for gamers looking for a high-performance television. The TV is equipped with four HDMI 2.1 ports, allowing connection to the latest consoles like PlayStation 5 and Xbox Series X, utilising full functionality including Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM). Thanks to the Game Bar feature, gamers can quickly and easily manage all game settings without needing to navigate complex menus. Parameters such as VRR, ALLM, Multi View, and frame rate monitoring can be adjusted. The TV also supports G-Sync and FreeSync technologies, which is particularly important for owners of Nvidia and AMD graphics cards. G-Sync and FreeSync synchronise the TV's refresh rate with the graphics card. The 120Hz panel guarantees incredible motion smoothness and image clarity. Combined with the Black Frame Insertion (BFI) feature, which is available at 60Hz and 120Hz, gamers can enjoy an even sharper and smoother picture. LG QNED87 is a television that meets the expectations of even the most demanding gamers, offering modern technologies and features that significantly enhance comfort and satisfaction during gaming.

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.

The LG QNED stands out with an extremely low input lag, which is crucial for smooth and responsive gaming. For a refresh rate of 120Hz, the input lag values do not exceed 6 ms, while at 60Hz, the input lag is a maximum of 15 ms. These are truly impressive results that ensure a player's reactions are almost instantaneously reflected on the screen.

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.

The LG QNED television works perfectly with a computer, offering very good font readability. This makes working and browsing content exceptionally comfortable. The high refresh rate of 120Hz provides a smooth and vivid image. It combines a large workspace with performance, making it a genuine pleasure to use. However, for more demanding users, it may be disappointing that the TV has issues displaying fonts on a dark background. Instead of white letters, they take on a greenish hue.

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.

When it comes to viewing angles, LG QNED87 performs really well. Thanks to its IPS panel, it offers wide viewing angles compared to VA panels. This means that the picture remains clear and does not lose quality even at an angle. While it may not achieve the perfect results of OLED TVs, which maintain colours and brightness regardless of the viewing angle, in terms of LCD QNED87 screens, it stands out positively. This makes it a great choice for larger rooms where viewers often watch at an angle.

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.

During the day, the LG QNED television performs adequately. It has a satin finish that doesn’t suppress reflections the best, which can be noticeable in bright rooms. Nevertheless, with quite good brightness at 430 nits, the image remains visible and clear. Although reflections may be somewhat bothersome, the brightness of the television allows for comfortable use during the day.

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.

LG QNED87 TV offers a multitude of features that significantly enhance user comfort. Let's start with the WebOS system, which we believe has the most user-friendly interface among all TVs available on the market. One of its greatest advantages is the remote control with a built-in gyroscope, known as the Magic Remote. Thanks to this, navigation is intuitive and quick, making TV usage a pleasure. WebOS also supports a range of smart features that greatly simplify everyday use of the television. Among them is AirPlay, which allows easy content sharing from Apple devices such as iPhone or iPad. Additionally, the TV supports a wide range of streaming applications, such as Netflix, YouTube, Amazon Prime Video, and many others, providing access to favourite movies and series in one place. When it comes to everyday use, LG QNED87 does not disappoint. The TV offers a USB recording feature, which is becoming increasingly rare in modern models. This allows users to record their favourite programs and watch them at any time. Furthermore, the TV has a Picture-in-Picture (PIP) function, although only for one tuner, enabling the viewing of two programs simultaneously. Connecting additional devices via Bluetooth is simple and hassle-free. The TV supports various Bluetooth devices, such as mice, keyboards, and headphones, increasing its versatility and allowing easy personalisation of the user experience. With all these features, the LG QNED87 TV is a versatile and convenient device that meets the expectations of even the most demanding users.

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 media player in the LG QNED87 television should not disappoint anyone. It offers rich capabilities when it comes to playing video and audio files. It supports many popular formats, ensuring versatility and user convenience. The only drawback might be the limited number of supported photo formats. However, this mainly concerns those less popular formats, so most users should be satisfied with the player's functionality. For everyday use and typical multimedia formats, the player performs very well.

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.

When it comes to sound, it can be said that it's moderately pleasant. There's a lack of pronounced bass, and the mid tones seem a bit unclear. This isn't an ideal situation for audiophiles, but it's worth noting that the television plays DTS files without any issues. This is a feature that's missing in many other televisions, so the LG QNED87 deserves praise for this support.
