LG QNED87T6B vs Samsung U8000F (IPS)

The QNED87T6B provides a solid HDR performance, delivering an impressive visual experience in many aspects. With a brightness approaching 500 nits, it offers good visibility of fine details in high-dynamic scenes. Support for HDR10 and HLG ensures the content appears well on the screen, though the absence of more advanced formats like Dolby Vision or HDR10+ limits the potential for optimal brightness and detail in certain scenes. Without dynamic metadata, the TV may struggle to reproduce fine details in very bright areas, where these advanced standards would typically make a difference. However, its excellent coverage of the DCI-P3 colour gamut (96.4%) provides vibrant, natural colours, enhancing the overall visual quality of 4K content.

Better does not mean good – and that perfectly summarizes the capabilities of the U8092F when it comes to displaying bright movie scenes in HDR mode. The brightness of the panel is just under 250 nits, which is definitely too little to enjoy any lighting effects. An interesting situation was noted during the measurement of the fourth scene from the movie Sicario 2 – the television clearly dimmed the entire screen in an attempt to achieve better black levels (which are still weak). One could even suggest that the device uses some form of "global dimming," but unfortunately, the results are still very poor. To make matters worse, the television does not support a wide color gamut – the coverage of the DCI-P3 space is about 80%, so there’s no hope for truly vibrant colors. HDR images here look rather like lightly brightened SDR, and that's the form we would suggest sticking to when it comes to this television.

The LG QNED87T6B, even in its best factory setting, Filmmaker Mode, exhibits issues with colour reproduction. A significant problem is the white balance, where the blue colour tends to drop on the graph, causing a shift towards yellow. This results in a warmer hue than intended, which affects the naturalness of color reproduction, especially in scenes with white or neutral backgrounds. The Colour Checker test confirmed that certain colours are distorted and do not accurately reflect reality, which can make movie scenes seem less lifelike and distort details.

In terms of contrast, there are notable issues with the gamma graph, showing significant drops where the optimal value should be around 2.4. This results in the TV displaying darker areas brighter in some scenes, which reduces depth and dynamic range. Additionally, the EOTF (Electro-Optical Transfer Function) curve, which corresponds to brightness reproduction, shows an unnatural drop at the start, leading to lower accuracy in dark scenes. This diminishes the TV's ability to convey full black depth, causing details in darker areas to be lost. As a result, more demanding scenes may appear less realistic, with a noticeable loss of detail in shadows and dark areas.

The Samsung U8000F was tested in the best possible picture mode built into the TV, which is Filmmaker Mode. This mode should – at least in theory – offer a cinematic, reference-quality image without unnecessary enhancements. For SDR content (mainly HD/SD), the TV performed surprisingly well straight out of the box. White balance errors hovered around a value of 3, which is roughly at the threshold of perception. The only complaint could be about brightness management – the gamma chart showed a slight tendency to brighten or darken certain areas, but overall it performed quite well for this price segment.

Unfortunately, it looks much worse in HDR mode. Although the white balance wasn't terrible, the TV had significant color errors – particularly noticeable on the Color Checker chart, where almost every sample landed outside the target point. The HDR image simply looks unnatural, and colors can be shifted, dull, or too cool. This largely stems from the fact that the U8000F does not support a wide color gamut (DCI-P3). The TV is physically incapable of displaying accurate colors in HDR standard – and this unfortunately shows in every more demanding material.

After calibration, the LG QNED87T6B delivers impressive results with SDR content. The white balance has been improved, resulting in natural, harmonious tones across various scenes. The precise gamma tuning allows for accurate reproduction of details in both dark and bright areas, making the TV perform excellently in everyday use. The overall image is vivid and well-balanced, with solid colour quality in HD. The contrast has also improved, with the gamma chart showing fewer significant errors, providing a more refined viewing experience.

In 4K HDR, the white balance continues to perform well, though some errors remain at the end of the chart. These might be linked to the TV's aggressive local dimming, which can affect colour accuracy in certain scenes. While the TV does not fully improve brightness as indicated by the EOTF curve, its inherent construction limitations prevent it from achieving perfection in this area. The Colour Checker test highlights an issue with colour saturation, as the TV, despite offering a wide colour gamut, cannot fully capture what the director intended.

Nevertheless, the overall picture quality after calibration is considerably better than before. The improvements in white balance and gamma tuning result in more vivid and realistic colours, enhancing the viewing experience despite the remaining shortcomings.

Although the U8000F offered quite a decent picture in SDR right out of the box, we were able to adjust it a little more. We managed to eliminate a slightly purplish tint and calibrate the gamma to a more reasonable level. However, the television still tends to overemphasize the smallest and brightest parts of the image – the gamma chart shows a characteristic "dip" that is difficult to completely correct.

Unfortunately, the situation looks worse in HDR. It's hard to talk about any significant improvement here – the television is simply not designed for HDR content. We tried to adjust the picture in the advanced settings, but despite everything, the color errors remained quite large – a delta E above 7 indicates noticeable deviations. It's a bit of a shame, but that's the charm of a budget design. In SDR, the U8000F performs just fine, while HDR is simply not its league.

When it comes to lower-quality content, the LG QNED87T6B performs admirably, with smooth gradation effectively addressing problematic areas in the image without negatively impacting the film grain. For optimal results, setting the "Smooth Gradation" feature to a low level delivers the best effect, significantly enhancing the viewing experience of lower-resolution materials by making them smoother and more visually appealing.

The TV handles digital processing well, ensuring the image is displayed without overscan or clipping. While slight jaggedness may be noticeable on certain fine details, such as branches against a background, the overall presentation remains impressive. Users will be satisfied with the quality of the image when watching lower-quality content, such as standard television, as the TV does an excellent job of enhancing the visual experience.

When it comes to how the Samsung U8000F handles lower-quality materials, we have to admit that Samsung has made progress compared to its predecessor from last year – the DU7192 model, which theoretically occupies the same place in the lineup.

This year's model is equipped with a function to improve the fluidity of tonal transitions, which has been implemented much better than last year. Yes, the television still uses quite strong algorithms that can distort details or remove film grain, but even so – it can be confidently said that it works effectively.

However, not everything went perfectly. The U8000F has noticeable issues with slight frame cutting when watching very old content in very low resolution. If someone plans to play their old VHS tape, they should be prepared for the image to appear slightly “cut off.”

The LG QNED87T6B delivers decent motion smoothness, particularly with the "TruMotion" feature, which allows users to adjust motion smoothing on a scale from 0 to 10. The "De-Judder" setting helps regulate the smoothness of motion, while the "De-Blur" option enhances motion sharpness. This provides flexibility for users to choose between a more traditional cinematic effect with slight judder (lower settings) and a smoother, more theatrical image, which, while slightly deviating from the cinematic standard, can be appealing to many viewers.

For gamers and sports fans, the 120Hz panel ensures an immersive experience, while the IPS technology offers better response times compared to comparable VA panels at a similar price. This results in smoother gameplay and more dynamic viewing of fast-paced sports events, making the QNED87T6B an excellent choice for those seeking high-quality motion performance.

The Samsung U8000F is equipped with a 60 Hz panel, so right from the start, it’s clear that we shouldn’t expect any miracles. This is simply the standard in this class – sufficient for everyday viewing, but without any fireworks.

The TV offers one motion smoothing slider – a feature called "Motion Blur Reduction", which allows us to adjust the smoothness of the image in movies. Higher settings provide a more "theatrical" and smoothed effect, while lower settings help retain the original character of the film with a slight 24p effect. Interestingly, there is a feature called "Clear Motion LED", which is a BFI mode – that inserts black frames between the frames of the picture to improve motion clarity. However, in practice, the screen flickers significantly when activated, and it should be regarded more as an experiment than something that realistically enhances gaming comfort.

The LG QNED87T6B is a top-tier choice for gamers seeking high-performance features. It is equipped with four HDMI 2.1 ports, allowing seamless connection to the latest consoles like the PlayStation 5 and Xbox Series X. This ensures full functionality, including support for Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM), which provide a smoother and more responsive gaming experience. The Game Bar feature enables easy management of gaming settings, allowing users to adjust VRR, ALLM, Multi View, and monitor the frame rate without navigating complex menus.

Additionally, the TV supports G-Sync and FreeSync, which are crucial for gamers using Nvidia and AMD graphics cards. These technologies synchronize the TV's refresh rate with the graphics card, reducing screen tearing and stuttering. With a 120Hz panel, the LG QNED87 delivers exceptional motion smoothness and image clarity, while the Black Frame Insertion (BFI) feature, available at 60Hz and 120Hz, further enhances visual fluidity. Overall, the LG QNED87T6B meets the demands of even the most discerning gamers, offering a comprehensive range of features that elevate the gaming experience.

Samsung U8000F offers a basic set of features for gamers, which nonetheless may be sufficient for less demanding users. We have an automatic game mode here – when a game is launched on the console, the TV automatically switches to low latency mode, which significantly improves response time. We also find the VRR feature, or variable refresh rate, which operates within a range of 48 to 60 Hz. This means that both Xbox and PS5 will not produce the "tearing" effect, as long as we stay within this range.

And unfortunately, that's about it for the advantages. Add-ons like Game Bar or higher refresh rates are reserved for the higher models of Samsung from the 2025 line. In theory, the TV also supports the HGiG feature, which should adjust HDR images to the intentions of game developers. Unfortunately – even though this feature appears in promotional brochures and store materials – its configuration on the Xbox console turned out to be... impossible in practice.
