LG QNED87T6B vs Samsung Q7F

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.

Unfortunately, the Samsung Q7F is not one of the brighter televisions, and this has a direct impact on the quality of HDR films. The peak brightness of the panel is just around 250 nits, which is definitely too low to speak of true cinematic experiences. In practice, the image in HDR content does not differ significantly from classic SDR, making it difficult to talk about any "wow effect" that usually accompanies us when watching such films. During tests of film scenes, the image simply looked dark, and the brightness almost always hovered around the aforementioned 250 nits. The worst performances were with shots that included small, intensely shining elements – the global dimming technique used reacted very aggressively in these cases, dimming the entire screen to maintain the effect of black. However, it is worth noting the presence of the QLED coating that expands the colour palette. For a budget QLED model, the Q7F performs quite decently here: the coverage of the DCI-P3 palette is about 93%, and BT.2020 reaches 70%. This means that, despite the low brightness, the colours can still look quite vivid and attractive.

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.

The factory colour accuracy of the Samsung Q7F is certainly not one of its strong points. In Filmmaker mode, which theoretically should be the closest to neutral, the issue with white balance immediately stands out. There is too much red on the screen, while blue is lacking. The consequences of this are very easy to notice – white, instead of being neutral, takes on warm, almost slightly orange tones. In the long run, this makes the entire image look somewhat unnatural, and bright areas of the scene may seem unrealistic. The problems become even more evident in HDR content. The graphs show that the television has significant errors in the Color Checker palette, which translates to visible inaccuracies in the actual image. Practically, this means that the colours are not presented as they should be. The Q7F also heavily manipulates brightness; darker elements are overly boosted, losing their cinematic quality, while bright parts may appear dimmed. As a result, the image seems flattened, and contrast, instead of helping to bring out details, only highlights its own limitations. This is particularly frustrating in HDR material, where every detail matters. In scenes where there should be a subtle play of light and shadow, the Q7F either oversteps by brightening too much or conversely – suppresses elements that should draw the eye. This causes the image to lose its depth, and instead of cinematic realism, we have a rather simplified effect.

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.

After professional calibration, we managed to bring the Q7F into order – at least in terms of SDR content. The picture in this mode looks really good: the white balance has been set correctly, the colours appear natural, and errors in the colour palette have dropped to levels that are practically invisible to the eye. Gamma behaves exemplary, and the only minor drawback is a slight lightening of smaller elements, which results from the lack of local dimming. For everyday watching of television or films in standard quality, the Q7F performs surprisingly well.

It was significantly harder to tame HDR content. Despite adjusting the white balance, the television still heavily manipulates brightness, causing scenes to sometimes look unnatural – what should be subtly darker can be overly brightened, and bright areas of the picture can occasionally appear dimmed. The end result is better than in factory settings, but it is evident that the structural limitations of the Q7F do not allow for the full potential of HDR materials to be fully realised.

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.

Upscaling and digital image processing on the Q7F is a bit of a sine wave. On one hand, we have really nice upscaling – weaker sources look better than one might expect. The image becomes clearer, sharper, and even older films or terrestrial television perform adequately. Samsung has been strong in this area for years, and the Q7F confirms that. On the other hand… there are some issues. The television has a problem with overscan – part of the image is simply cut off, and it doesn't look very elegant. Additionally, we were let down by a feature called "noise reduction", which should improve the smoothness of tonal transitions in weaker materials. In other Samsungs, it works relatively well, but here it makes practically no difference – the banding in gradients is still there. It's a bit of a shame, as one could have expected more from a model that is aimed at users looking for a display for SDR content.

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.

Ghosting and motion smoothness in the Q7F are probably the most budget-friendly elements of this television. The 60 Hz panel makes itself known, with noticeable ghosting, especially in dynamic scenes, and it's rather difficult to regard this model as equipment designed for watching sports or playing fast-paced games. In tests with the little green man, a long trail was left behind, similarly to how a ball in a football match would leave streaks.

On the plus side, the presence of motion smoothing must be acknowledged. In films, it actually makes a difference – especially since most material is recorded at 24 frames per second. Here we can decide whether we prefer a more "cinematic" image, with slight judder typical of cinema, or a smoother, more "television" approach. This part works quite well and helps to improve the viewing experience for series and films.

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.

Features for gamers in the Samsung Q7F is a topic that evokes quite a lot of mixed feelings. On the one hand – no sensible person expected miracles here, as it is after all a 60 Hz television and it was clear from the start that it would not be a device for squeezing the maximum out of a console or PC. On the other hand, since the manufacturer promised specific solutions in promotional materials, it is natural that we wanted to see them in practice. At the outset, it’s quite decent. The automatic game mode (ALLM) works, so there’s no need to manually fiddle with the settings; the console automatically switches the television to low-latency mode. Additionally, we have the Game Bar, which looks impressive and allows you to check a few basic parameters without leaving the game. And this is where the good news ends.

The biggest problem with the Q7F is VRR, or rather its absence. Yes, an appropriate icon appears in the menu, and you can even see it in the Game Bar, but throughout the entire test, the feature remained inactive and could not be enabled in any way. The situation with HGiG is even more painful; this option was indeed available at the beginning, but after a software update, it completely vanished, which is simply unprofessional. Therefore, the Q7F is only suited for the absolute basics. Of course, you can turn on the console, play some calmer titles, and enjoy low input lag, but if someone is counting on more advanced features that the manufacturer promised, they will be disappointed. This is not a television to buy with gaming in mind, and it's better to be aware of that before making a purchase.
