LG QNED87T6B vs Panasonic Z85A

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.

The Panasonic Z85A is an OLED television, so you can expect great effects in movies right away. And indeed – our tests show that the WOLED panel can achieve around 800 nits of peak brightness in optimal conditions. This is a solid result that performs well in most demanding HDR scenes, allowing you to enjoy a dynamic and detailed image. However, like every OLED, the Z85A has its limits. In very bright scenes that cover the entire screen – like the final sequence from the movie The Meg – the television reduces brightness to about 400 nits. This is standard behavior for this technology, so if someone plans to watch movies in a brightly lit living room, it's worth keeping this in mind. The coverage of the DCI-P3 color gamut at 98% also deserves a big plus. As a result, the television delivers a wide range of colors that stand out with vibrancy and depth, and details in HDR scenes are sharp and precise. In short – the Panasonic Z85A provides a solid HDR effect that will satisfy any movie enthusiast.

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 Panasonic Z85A offers many picture modes, but the Filmmaker mode definitely stands out from the rest. It is rare for a television to be so well-tuned straight out of the box, and the unit we had the opportunity to test really impressed us positively.

However, there were some minor shortcomings. In the SDR signal, we noticed a slight deficiency in red and blue colors, which made the image have a cooler shade than it should. This is particularly evident in the comparative photo. Conversely, in 4K HDR materials, the situation was the opposite – the excess of red made the image seem warmer than the creators intended. In terms of brightness characteristics (gamma) and maintaining the appropriate EOTF curve, it is hard to find fault. There are some minor deviations, but they are so minimal that the average viewer is unlikely to notice them.

It is also worth emphasizing that our observations pertain to a specific unit of the television. Two identical models can differ from each other due to natural production variations. Nevertheless, the unit we had in hand is really solid and deserves praise. Now it's time for our calibration – we'll see if we can squeeze even more from this screen!

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.

The Panasonic Z85A offers truly wide possibilities when it comes to image settings, so we enthusiastically set about calibration. Although we mainly focused on white balance correction, the final effect exceeded our expectations. Both HD and 4K HDR content now present nearly perfect color reproduction, with minimal errors that are difficult to catch with the naked eye. Well-calibrated televisions are rare, and we must admit – it is truly gratifying. Although gamma and EOTF curve did not require drastic adjustments, we managed to further stabilize their characteristics across the entire brightness scale. After calibration, the Panasonic Z85A is a true gem for home cinema enthusiasts. The image is precise, colors are natural, and every scene looks exactly as the director intended.

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.

Now that we know how the Panasonic Z85A handles tonal transitions in 4K materials, it's time to look at its "Gradation Smoothing" feature. It works, but unfortunately not entirely effectively. Regardless of the selected value – whether low, medium, or high – we were unable to achieve perfectly smooth tonal transitions in our test sequence. We recommend setting this feature to an intermediate level. While it may slightly blur fine details, it at least avoids the problem of losing film grain, which can be crucial for many viewers when watching classic productions.

When it comes to image scaling, the television performs quite well. It is evident that the image is slightly sharpened, and thin lines can sometimes appear somewhat jagged. However, this is standard in most televisions and fortunately, it can be adjusted using the sharpness slider. This gives us full control – we can achieve a more plastic, blurred image or a clearer one, though more "harsh" and artificially sharp. It all depends on the user’s preferences and the type of content we are watching. Overall, the scaling is at a solid level and should satisfy most users who are using lower resolution materials.

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 Panasonic Z85A has a 120 Hz panel, which will surely please both gamers and sports fans. Sure, it's not 144 Hz like some gaming TVs, but in practice, the difference is really hard to notice. In games, the image is stable and clear, and during fast action, there's no sign of any motion blur. The same goes for sports – a quick run by a soccer player or a dynamic car maneuver looks smooth and natural. The TV also has an "Intelligent Frame Creation" feature, which is a motion smoother. There are two sliders – one for reducing motion blur and the other for motion smoothness. With these, you can adjust the picture to your personal preferences – whether you prefer a more cinematic effect with gentle transitions between frames or a maximally smooth image perfect for watching sports.

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.
