Samsung Neo QLED QN90D / QN92D vs Panasonic Z85A

During synthetic tests, the Samsung QN92D demonstrated remarkable brightness capabilities, reaching an impressive 2000 nits—on par with top models in the market. This level of brightness puts it at the forefront for displaying HDR content, where high brightness is essential. But how does it fare in real movie scenes? Under favourable conditions, such as the light-drenched opening and closing scenes of Life of Pi, the QN92D nearly replicates its lab results, delivering striking brightness levels. However, performance changes in scenes featuring small, bright objects against dark backgrounds, such as the fourth scene in Sicario. Here, brightness levels drop significantly, with maximum values capping at around 600 nits.

As with contrast, these limitations are due to the aggressive local dimming algorithm, which aims to reduce the "halo" effect around bright objects in dark scenes but often sacrifices overall brightness. Consequently, while the TV excels in scenes with abundant light, it faces challenges maintaining brightness with smaller, bright elements on dark backgrounds.

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 best mode for colour reproduction on the Samsung QN92D is Filmmaker mode. Although it generally offers good colour quality, it is not without significant issues. Starting with HD/SDR image quality, the main challenge is white balance. The graphs reveal considerable instability, with a dominant red tint that makes the image appear too warm. This imbalance causes shades to shift unnaturally towards warmer tones, potentially affecting the perception of natural colours. Additionally, while contrast, as indicated by the gamma chart, is not the worst, it still falls short of the ideal, impacting overall image quality, especially in darker scenes.

This issue continues with 4K content, such as high-quality series or films. Here too, white balance proves problematic, with noticeable deficiencies in both blue and red, leading to tonal shifts. Tests using the Colour Checker tool confirm these issues, showing a tendency for colours to skew toward yellow hues, further distorting the natural look of the image. While Filmmaker mode remains one of the best options for cinematic content, it could still benefit from improvements, particularly in colour accuracy and white balance.

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 Filmmaker mode on the Samsung QN92D shows significant improvement, particularly with SDR content. The white balance has been greatly enhanced — previous colour shifts and red dominance have been corrected, resulting in more natural colour reproduction. Although the gamma curve didn’t require major adjustments, its stabilisation has positively impacted overall picture quality.

In high-quality materials, the white balance has also improved. However, contrast remains an area to watch. The EOTF curve initially appears accurate, but closer inspection reveals that the television struggles to maintain consistent contrast in film content, indicating further room for improvement. Despite these areas, one advantage is the TV’s colour saturation. Skin tones are rendered well, and while some colours may be slightly oversaturated, the overall effect is rich and vibrant.

Despite minor contrast limitations, the calibrated Filmmaker mode on the Samsung QN92D delivers excellent picture quality, with natural colours, making it a strong choice for movie watching.

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.

Let's examine how the Samsung QN92D television manages tonal transitions in low-quality materials. The noise reduction function is highly effective, enhancing the fluidity of tonal transitions even under challenging conditions. However, it’s worth noting that, as with other Samsung televisions, this feature can occasionally remove desirable elements, such as film grain, which may affect image authenticity. 

In terms of digital processing, the Samsung QN92D also performs impressively. During testing, the image appeared natural and well-balanced, with details like background branches precisely reproduced, underscoring the television’s ability to enhance the quality of low-resolution materials.

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 Samsung QN92D TV features a 144 Hz panel, however, when using the motion smoother, the maximum refresh rate adjusts to 120 Hz. This setup ensures excellent picture quality for both gamers and sports enthusiasts. Additionally, the TV offers a range of image enhancement options, such as the "blur and judder reduction" feature, which lets users fine-tune smoothness on a 10-point scale. Blur reduction sharpens fast-moving objects, while judder reduction smooths out motion, eliminating the "stutter" effect. With these advanced settings, the Samsung QN92D provides optimal visual experiences for dynamic scenes and intense gameplay alike.

The TV performs impressively in terms of motion blur, with minimal issues. The only minor drawback is a slight overshoot effect noticeable on dark backgrounds in our "Ufoludkiem" test. Nonetheless, with its advanced smoothness settings, the Samsung QN92D delivers outstanding performance for both fast-paced scenes and immersive gaming sessions.

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 Samsung QN92/QN90 TV is an outstanding choice for avid gamers and is highly recommended. This model provides virtually every gaming feature currently available, enhancing the excitement of gameplay. A standout feature is the 120 Hz panel, delivering impressive motion smoothness, which is especially beneficial during action-packed games. The TV also boasts low input lag, ensuring quick responses to player commands. Additionally, VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode) optimise refresh rates and automatically activate gaming mode, further elevating the gaming experience. An additional bonus is the Xbox app, enabling users to play directly on the TV without needing a console—an exclusive feature in Samsung TVs, adding to their appeal in the gaming world.

Samsung’s Auto Motion Plus Game feature deserves particular praise. This motion smoother is highly effective in gaming, making lower frame rates appear smoother—30 frames per second can look like 45, and 60 Hz can resemble 90 Hz. Crucially, it achieves this without introducing noticeable input lag (keeping it below 25 ms), so gameplay remains highly responsive, unlike many other motion-smoothing options on the market. As a result, players can enjoy a smoother visual experience without sacrificing responsiveness.

Panasonic is mainly associated with home cinema televisions, but the Z85A shows that it can also enter the gaming world with a really strong punch. This is equipment that can easily be called a gaming beast - it has everything needed for comfortable gameplay.

Even though we only have two HDMI 2.1 ports, both operate at full bandwidth, so we can easily connect both a next-gen console and a gaming PC. All key features are supported: ALLM automatically switches the TV to game mode, VRR ensures smooth images without stuttering and tearing, and with properly implemented HGIG and Dolby Vision, HDR games look really good - colors are vivid, details clear, and dark scenes readable. There is also a Game Bar in the form of a clear, circular menu. It may not look as impressive as with the competition, but it is intuitive and contains all the most important settings that we would like to have at hand during gaming.

In summary - the Panasonic Z85A is equipment that really surprises with its gaming capabilities. It is a television where both console gamers and PC gamers will feel at home. It's smooth, dynamic, and simply good.
