LG QNED87T6B vs LG QNED80A6A (VA)

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.

Let's talk now about how this TV shines. If you expect dazzling light effects, we need to cool your enthusiasm. The LG QNED80A is a moderately bright television. Our measurements in most movie scenes indicated values around 350-400 nits. That's not enough to speak of a full, cinematic HDR experience and the sense of that famous "high dynamic range" that flagship products offer. However, brightness is not everything. Although the QNED80A is not a "light monster," it makes up for it in another key category: colors. Here, the PFS technology comes into play, which LG marketers hide under the name QNED/NanoCell. Thanks to this process, the TV offers a significantly wider color palette than classic LCD designs. In our tests, the coverage of the cinematic DCI-P3 palette reached a solid 93-94%. What does this mean for you? That even at lower brightness, when watching movies in HDR, the colors will be vivid, deep, and properly saturated. The image is not washed out but lush, which is a significant advantage in this price range.

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.

It might seem that since the QNED80A is one model, it should offer the same picture regardless of the version. However, practice shows something completely different. Analyzing the variant with a VA panel in the best factory setting – that is, in Filmmaker Mode – we noticed a specific characteristic. This TV “out of the box” serves us a picture with a clear dominance of red and a deficiency of blue. The overall image is very warm, almost hot. Many users might describe this as a “too cinematic” image, approaching sepia. Additionally, there's the issue of the gamma curve – the TV tends to slightly, artificially brighten scenes (the gamma is too low), causing the picture to lose some of its plasticity. The good news is that these are not flaws of the panel, but merely of the software. As always in our tests, we carried out a professional calibration, which completely eliminated these shortcomings, restoring the natural white balance and correct saturation.

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.

Was it worth spending time on calibration? Definitely yes. We managed to tame the initially too warm white balance and, most importantly, correct the gamma curve. The TV stopped artificially brightening scenes, which added depth to the image. The biggest improvement is visible in SDR content, meaning when watching regular television, YouTube, or in games without HDR. Here, the QNED80A shows its class – color reproduction errors (DeltaE) dropped below a value of 2. In technical terms, this means that the errors are practically unnoticeable to the human eye. The image in everyday use has simply become very attractive, natural, and correct. The difficulties begin with HDR content. Even though we managed to improve the white balance, the EOTF curve graph (responsible for brightness at various levels) shows that the TV still "interprets" the image in its own way. This is due to the nature of the edge-lit local dimming used and the fact that LG gives the calibrator a very limited range of control over this parameter. In short: the TV struggles to hide its hardware shortcomings, sometimes ignoring our commands. Nevertheless, the final image is much more accurate and pleasant to the eye than in factory settings, even if it still falls short of studio ideal.

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.

In this category, the QNED80A proves to be a real "dark horse." It's a fantastic, affordable television for those who often watch lower quality materials – for example, from traditional cable TV. The processor used here handles upscaling exceptionally well, meaning it enhances low resolution to native 4K. The image after processing is natural, smooth, and most importantly – not overly jagged or artificially sharpened. In the menu, we also find a dedicated option for smoothing tonal transitions in low-quality material. This feature works really effectively, eliminating the annoying "banding" of colors in heavily compressed video. However, we must remain vigilant. Remember that we are not dealing with a top-tier processor known from flagship OLED models. In more challenging scenes, the system may struggle and introduce minor artifacts or distortions. Nevertheless, it's definitely worth giving this feature a chance, as in most cases, the improvement in quality is noticeable to the naked eye.

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.

We move on to a matter that may be decisive for many. Unfortunately, here we must point out the biggest "Achilles' heel" of the QNED80A model. This TV is equipped with a panel that has a native refresh rate of 60Hz. There's no point in hiding it – at this price, we expected more because we know that Chinese manufacturers can offer 120Hz screens for similar money. Due to this parameter, dynamic scenes in sports or fast-paced games are not the strong suit of this screen. Fortunately, LG has equipped the TV with a proven smoothing system called TruMotion. It works quite well with film material (24 frames). We suggest playing around with the De-Judder slider – from our experience, setting it in the range of 2-4 provides the best compromise: motion becomes smoother while still looking natural, without the artificial "TV theater" effect.

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.

Since we have established that the QNED80A is a 60Hz panel television, we must say it directly: we will not be playing here at 120 frames per second in any resolution. Does this disqualify the device in the eyes of gamers? Not necessarily, especially for "casual" gamers. LG has decided to sweeten this technical limitation by packing in quite a few useful features. We have support for VRR (Variable Refresh Rate) ranging from 48-60Hz and an automatic game mode ALLM, which quickly reduces input lag upon detecting a console. We manage all of this through a very convenient, purple Game Optimizer menu (Player Panel), which has already become LG's trademark. The manufacturer deserves big credit for consistency regarding HDR. Although the television does not support Dolby Vision in games on Xbox consoles, LG adds a well-implemented HGiG standard. Thanks to this, even on a moderately bright screen, HDR gaming is clear, and details in shadows and highlights are accurately reproduced, rather than "cut off."
