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

Samsung Q70D performed in the test just as it should for its category – very well. The strongest points of the television are undoubtedly its efficiency when using a console and the colour reproduction after undergoing the calibration process. The former will certainly not allow gamers to remain indifferent to the range of benefits that Samsung Q70D can offer, and there are indeed many, including this almost exclusive feature for the manufacturer’s units – the ability to smooth out gameplay while maintaining a reasonable input lag, which allows 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 correctly set up, is on par with games using Dolby Vision. One should also not overlook the ease of pairing the television with the Canal+ decoder, which is not such an obvious advantage, but we know that many people struggle with this issue. Staying on the topic of television, it must be acknowledged that the Samsung Q70D offers very good brightness in SDR materials for its price range, making daytime viewing more than comfortable. A downside for the tested television has to be the lack of Dolby Vision, which would have greatly enhanced the maximum brightness of the Samsung Q70D. One should also not overlook the construction flaws of the device, which may (though not necessarily) lead to light bleed, which can be noticed in dark conditions on less bright scenes. What cannot be taken away from Samsung Q70D is the fact that it features one of the better motion smoothing technologies in its price range, which works excellently in the context of sports events or fast-paced action scenes. The system that operates the television runs very smoothly, and the only complaint one might have is the lack of the Tidal app. In summary, the Samsung Q70D is a good continuation of the manufacturer's seventh series, which year after year gains – both in quality and popularity.

LG QNED87T is a television that definitely stands out. It is somewhat unconventional – it doesn’t forcefully compete with top OLED models, but it makes up for that with modern features and user-friendly operation. This is a device that works wonderfully for those who value convenience and versatility. The 120 Hz panel, VRR, and ALLM ensure that the television handles dynamic content well. 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 delays or blurring. When watching sports, fast actions are clear, without stuttering. On a daily basis, LG QNED87T is simply comfortable. WebOS operates intuitively, applications launch quickly, and the Magic Remote significantly simplifies control. Voice control saves time, especially when searching for films or series. Features such as USB recording and Bluetooth offer more options, increasing its versatility. The IPS panel is a significant advantage when it comes to viewing angles. Regardless of where we sit in the room, the picture looks good. It’s an excellent solution in larger spaces, where not everyone has a direct view of the screen. Older films or standard television from built-in tuners also look decent – the improvement in the quality of lower resolution materials works surprisingly well. However, there are certain things that may stand out. The contrast is simply tragic. In dark scenes, there are no details at all. In the evening, in a dimmed room, this is very noticeable. During the day, these imperfections are less felt, so LG QNED87T is better suited for well-lit places. LG QNED87T is a television that has its strengths. It handles dynamic materials well, is comfortable to use, and is perfect for bright rooms. It is not an ideal model for evening screenings in darkness, but in everyday use, it certainly stands out. It is a versatile device that is worth considering when choosing a new television.

Samsung Q70D and its related models, such as Q77D and Q74D, utilise a VA panel, which in itself should provide decent contrast. Typically, it is several times higher than in IPS/ADS screens that are not equipped with an advanced local dimming system. The contrast results, as you can see, are quite varied, which is caused by the non-uniformity of the panel. Therefore, at times we can achieve good contrast, whereas at other times it is significantly degraded, but generally fairly consistent, not counting light leakage. Let’s take a look at the film scenes we prepared from the films "Oblivion" and "Revenant". As we can see, in the first one, the lights are well separated from each other, which is a positive phenomenon, as visibility of details in the whites in further tests should be equally good. What stands out the most here is the unusual over-sharpening of 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 uneven backlighting of our scene. It was quite significant and heavily affected the perceived image. Nevertheless, the details in the film were well visible.

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

Although the manufacturer offers a dimming control option, the effects remain relatively weak. Test patterns show that the contrast is truly miserable, and in the test scene from the film "Sicario 2," it is clearly visible how the television struggles with uneven backlighting, illuminating a large portion of the screen from below. This demonstrates 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 fairly average level, although it cannot be said that the HDR effect will be unnoticeable. Any brightness above 400 nits allows for a clear distinction between SDR and HDR materials. As was the case in the paragraph about contrast and black levels, this time we can observe that the first scene, featuring a bright sun and a dark foreground, possesses the lowest luminance among the measured ones. The result, which can be considered very good for this price range and class of display, is the latter. In a scene where we see a large light source filling a significant part of the frame, the brightness of the television is at its highest, reaching nearly 500 nits. It is worth noting the quite low coverage of the wide DCI-P3 colour gamut, which occasionally results in noticeable gaps in the colour palette. Additionally, users can enjoy rich colours and high precision in shade reproduction, making movie screenings a special experience. It is also worth noting 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 scenes. Support for basic HDR formats, such as HDR10 and HLG, ensures appropriate 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 – 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 high as 96.4%. This ensures that the colours displayed by the QNED87T6B model are more vibrant and natural, enhancing the quality of 4K content with a wide colour palette.

The best factory mode on the Samsung Q70D is "Filmmaker," and it was this mode that we used during all our tests. Before calibration, it had several flaws that effectively prevented it from conveying the director's intentions. In both SDR and HDR materials, the white balance was dominated by red and green. As a result, there was a characteristic yellow tint on the image, causing white to appear yellowed and resulting in skin tones that were noticeably too warm. The lowered gamma in standard colour gamut materials resulted in a significant drop in contrast, which was already not the highest. This caused detail in the blacks to be accentuated but also led to overexposure in brighter scenes. The EOTF curve, in this case, proved to be much better and only brightened those scenes with relatively low luminance. This was perfectly evident in the section where we measured the television's maximum brightness in HDR materials. At that point, the frame from the film "Billy Lynn" was unnaturally bright and lacking in depth.

The colour reproduction in the LG QNED, even in Filmmaker Mode, which is the best factory setting, is not without flaws. The main issue is the white balance – we noticed that the level of blue on the graph tends to decrease. This results in a shift towards yellow tones, making the image appear warmer 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 cinematic scenes seem less realistic, and details are represented in incorrect colours, which negatively impacts the overall picture quality.

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

Fortunately, Samsung provides a wide range of calibration tools in all its televisions, including 2-point and 20-point grey scale adjustment as well as advanced CMS. This allowed us 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 generates is definitely closer to the reference. Higher deltaE errors in wide dynamic range content are primarily due to 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 the precise adjustment of the gamma, details in shadows and bright areas of the image are accurately reproduced. The television performs excellently in everyday use, offering vivid, well-balanced images and solid colour quality in HD quality. The greatest beneficiary here is also the contrast. The gamma chart has been freed from very large errors, so here the television has gained a second face.

As for the white balance in 4K HDR, it has also been significantly improved. However, certain errors still appear at the end of the chart. This could be due to the overly aggressive operation of the television's local dimming, which affects the accurate reproduction of colour in certain scenes. It is difficult to speak here of an improvement in brightness represented by the EOTF curve. Due to its construction limitations, the television has certain disadvantages and we are not able to overcome them. The Color Checker test confirms the issue with colour saturation – despite the television offering a wide colour palette, it is not able to fully convey what the director intended.

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

Considering how important lighting is in films and series, the overlapping structures and the fluidity of tonal transitions constitute an extremely significant element in assessing the quality of the image. The colour grading in the tested television stands at a fairly decent level. It cannot be said to be outstanding, but it is also not bad. We assess it as adequate. Brighter scenes perform best here, showing the least amount of stuttering. In scenes recorded in darker settings, slight deficiencies in grading can already be noticed, although this is not an issue that would cause discomfort while watching. This may be disrupted by the bleed of the backlighting, 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 slight flaws do not detract from the fact that the gradation is one of the positive aspects of this model. Overall, the television performs well with smooth transitions of colours.

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

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

When it comes to lower quality materials, the gradation looks really good. A feature called "Smooth Gradation" effectively smooths out the most problematic areas of the image without 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 and makes watching lower resolution materials more enjoyable and smoother.

In terms of digital processing, the image is displayed without cropping, known as overscanning. Although slight fringing of the branches against the model’s background can be noticed, the overall presentation is very good. Users should be satisfied with the image quality when watching low-quality materials, such as standard television. The television 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 featuring a 120Hz panel. Consequently, its motion smoothing functions are more advanced than those in lower-tier models. Within the menu, we find three functions responsible for improving smoothness: "Motion Blur Reduction," "Judder Reduction," and "Clear Motion (LED)." We will discuss the third one later. The first function is responsible for sharpness in motion, while the second adjusts the level of smoothing. The smoother in Samsung Q70D performs satisfactorily, and each setting brings noticeable changes. Therefore, those who dislike the characteristic juddering in films or are avid sports viewers will be able to achieve a personalised level of smoothing. In the picture, we present a setting with slight smoothing, without the soap opera effect.

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

The television provides decent smoothness when watching films, thanks to the "Tru Motion" feature that allows for adjustment of the motion smoothing level on a scale from 0 to 10. De-Judder adjusts motion smoothness, while De-Blur regulates motion sharpness. The user has the option to choose between a traditional, cinematic effect with slight judder (lower settings) and a smoother, theatrical image. Although the latter slightly deviates 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 certainly not disappoint them. And with the use of an IPS panel, the response time is generally better than that of VA panels available at a similar price. This guarantees 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 conducted tests, we did not find any negative effects related to this state of affairs. Moreover, and more importantly, Samsung Q70D supports all functions resulting from the aforementioned standard. This news will surely please all gamers, as it means that whether using a console or a PC, we can count on the highest possible comfort during gameplay. Given the typical absence of HDR Dolby Vision for this manufacturer, it is significant that the HGIG mode has been correctly implemented and there is no issue with setting the calibration checkerboard. We particularly note that Samsung, as the only manufacturer, allows gameplay with the smoothener turned 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 it has consistently refined since then. It contains all the necessary information regarding gameplay parameters that we can change "on the fly".

To summarise: Samsung Q70D performs excellently both with a console and a computer. All functions worked perfectly and there were no issues with them. The ability to enable the smoothener without a significant increase in input lag is a true game changer.

LG QNED offers a range of features that make it an excellent choice for gamers looking for a high-performance television. The television is equipped with four HDMI 2.1 ports, allowing for connection to the latest consoles, such as PlayStation 5 and Xbox Series X, and taking full advantage of features including Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM). With the Game Bar feature, gamers can quickly and easily manage all their game settings without having to navigate through complicated menus. It is possible to adjust parameters such as VRR, ALLM, Multi View, and monitor frame rates. The television 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 television's refresh rate with the graphics card. The 120Hz panel ensures incredible motion smoothness and image clarity. Combined with the Black Frame Insertion (BFI) feature, available at 60Hz and 120Hz, gamers can enjoy an even clearer and smoother picture. LG QNED87 is a television that will meet the expectations of even the most demanding gamers, offering modern technologies and features that significantly enhance comfort and satisfaction in gaming.

The latency results in Samsung Q70D are at a high level, regardless of the signal or resolution. All gamers will certainly appreciate the manufacturer's efforts, which allow for a game running in 4K 120 Hz with HDR to have a mere 7 ms latency, which is virtually unnoticeable even in online games. It is worth adding that the lag with the smoothness enhancer switched on increases by about twice, which still means very comfortable gaming in this case.

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

After connecting the television to the computer and wanting to use it as a monitor, we can expect a low input lag of 13 ms, which is practically unnoticeable along 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 one can confidently connect the Samsung Q70D to the computer as a monitor and anticipate comfortable work with text.

The subpixel arrangement is BGR, which does not negatively impact the use of the television as a monitor. However, since operating systems are not adapted to such a subpixel format, this may cause slightly less clear outlines. Nevertheless, this is practically negligible and only a handful of people may notice it.

The LG QNED television works excellently with a computer, offering very good font readability. As a result, working and browsing content is exceptionally comfortable. The high refresh rate of 120Hz ensures a smooth and vivid image. It combines a large workspace with efficiency, making it a real pleasure to use. However, for more demanding users, the disappointing fact may be that the television 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 the Samsung Q70D in terms of viewing angles is its Achilles' heel. Even a slight shift from the axis results in a significant loss of contrast and a substantial degradation of colours.

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

The satin finish of the panel in the Q70D allows for quite good performance in a strongly sunlit room. It is worth noting that the reflections do not extend beyond their source, thus not spilling over onto the rest of the panel. We also commend the maximum brightness of the television in SDR materials, which is 450 nits, allowing for comfortable content consumption during the day.

During the day, the LG QNED television performs acceptably. It has a satin finish panel that doesn't suppress reflections very well, which can be noticeable in bright rooms. Nevertheless, thanks to quite good brightness of 430 nits, the picture remains visible and readable. Although reflections can be somewhat distracting, the television's brightness allows for comfortable use during the day.

The operation of the Samsung Q70D is powered by the proprietary Tizen system. It is quite a well-known software, as the manufacturer has been developing it in its televisions for a really long time. Its main advantage is smooth performance and the absence of significant stutters, which we can confirm through conducted tests. The greatest downside, however, is its closed nature. Although the app store is quite extensive, we are still at the mercy of the manufacturer. Therefore, we will not be able to install missing items, even from a pendrive. A perfect example of this is this year's discontinuation of support for the Tidal app. On the other hand, a benefit, especially for users of Apple equipment, is the implementation of AirPlay, which allows for easy mirroring of content from a device to the television. Fortunately, Samsung has also provided the option to connect a keyboard and mouse for much quicker navigation through the television's menu. It is worth mentioning that the manufacturer has luckily included a remote that connects via Bluetooth this year, which often did not occur 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 any special skills.

In summary: The Tizen system is very smoothly functioning software, which is certainly a strong advantage of the television. Although more advanced users may complain about the lack of at least KODI, the rest will be satisfied.

LG QNED87 Television 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 televisions available on the market. One of its greatest assets is the remote control with an integrated gyroscope, known as the Magic Remote. Thanks to this, navigation is intuitive and fast, making the use of the television a pleasure. WebOS also supports a number of smart features that greatly simplify daily use of the television. Among them, we find AirPlay, which allows easy content streaming from Apple devices such as iPhone or iPad. Additionally, the television supports a wide range of streaming applications, such as Netflix, YouTube, Amazon Prime Video, and many others, providing access to favourite films and series in one place. When it comes to daily usage, LG QNED87 does not disappoint. The television offers a USB recording function, which is increasingly rare in today's models. This allows for recording favourite programmes and watching them at any time. Furthermore, the television has a PIP (Picture-in-Picture) function, although only for one tuner, enabling the viewing of two programmes simultaneously. Connecting additional devices via Bluetooth is simple and hassle-free. The television supports various Bluetooth devices, such as mice, keyboards, or headphones, increasing its versatility and allowing easy personalisation of the user experience. With all these features, the LG QNED87 television is a versatile and convenient device that meets the expectations of even the most demanding users.

The built-in player Samsung Q70D is one of its major advantages. It handled almost all video and audio files prepared for the testing process excellently. The only exceptions in this regard are, of course, the Dolby Vision format (which is not surprising) and less popular codecs. Additionally, credit should be given for the support of Polish characters and the ability to change font colours. However, it performs worse with photo formats, as it only supports JPEG among the popular ones. There is definitely a lack of formats such as PNG or Apple's HEIC.

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, providing versatility and user convenience. The only criticism that could be made is the limited number of supported image 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. The overall sound is fairly balanced, although we wouldn't advise increasing the volume above 2/4 of the scale. However, if we have a home cinema system, a number of codecs await us, notably featuring the most important ones, namely DTS-HD Master Audio and Dolby Atmos.

When it comes to sound, one could say it is moderately pleasant. There is a lack of pronounced bass, and the mid-tones seem somewhat unclean. This is not an ideal situation for audiophiles, but it is worth noting that the television has no trouble playing DTS files. This is a feature that is lacking in many other televisions, so the LG QNED87 deserves praise for this support.
