Samsung QN900D Neo QLED 8K vs Panasonic Z95A

Under synthetic testing conditions, the television showcased its impressive light output, achieving 1400 nits, which is undeniably remarkable. This capability was also evident in the opening scene of Life of Pi, featuring a vibrant sunrise. However, due to certain dimming algorithm issues, some drawbacks are noticeable. For instance, in test scenes from Sicario 2 and the second scene of Life of Pi, the brightness levels dropped to an average of 500-600 nits. While this performance isn't poor by Mini LED standards, expectations were higher given the premium price of the TV. Nonetheless, the set should be commended for covering a wide colour gamut of DCI-P3 at around 96%. Although some technologies offer higher coverage, this is still a commendable result.

Panasonic Z95A demonstrates class when it comes to HDR performance. In brightness tests, it reaches a level of 1800 nits, which has a real impact on watching movies. Scenes from Life of Pi or Gemini Man look great – the television effortlessly reproduces details and the intensity of bright spots, impressing with its power. In more demanding moments, like the final scene from The Meg, one can see how bright light floods the screen. In such moments, brightness drops, which is typical for organic matrices. Nonetheless, a result around 1000 nits can still be considered excellent, still providing very good picture quality. Additionally, the television offers excellent coverage of wide color gamuts – up to 98.6% for DCI-P3 and 74.5% for BT.2020. This ensures that colors are not only vibrant but also deeply saturated, allowing full appreciation of the richness of details, especially in HDR scenes. Such coverage makes colors appear more realistic, and the HDR effect gains in intensity and accuracy. All this impressive HDR effect is thanks to MLA technology, which enables achieving such high luminance and excellent image detail. Thanks to this, the Panasonic Z95A offers HDR at a level that truly makes a difference.

The television includes a Filmmaker mode, intended to present films in the most authentic way possible, but it does come with some issues. For HD content, the white balance shows a dominance of red and blue, giving the image a pinkish hue. Conversely, for 4K HDR content, the levels of blue and red drop, resulting in a warming effect that shifts colours towards yellow tones. Colour Checker tests confirm this tendency, with colour samples visibly drifting in this direction.

In terms of brightness and contrast, the gamma is notably disrupted. The main issue is a marked spike at the start of the graph, indicating that dark details are excessively brightened, which reduces depth in the darkest parts of the image due to zone dimming. For 4K HDR content, the EOTF curve performs reasonably well but falls below the reference level, affecting the overall image dynamics.

The best picture mode in the Panasonic Z95A is undoubtedly the Filmmaker mode. It is a mode that offers quite good image reproduction, but it is not free from certain errors that need improvement. First of all, the white balance, both for 4K and HD content, tends to show a dominance of red and blue colors. This causes a slight pinkish tint in the image, particularly noticeable in bright, white scenes. Such deviations can be seen in the comparative photo below, which illustrates this problem well. The Colour Checker test also confirms these discrepancies, showing slight shifts of the dots towards the mentioned hues.

In terms of gamma brightness characteristics, it performs very well, with only minor issues when lightening small details. The EOTF curve, which is responsible for controlling brightness in 4K HDR content, poses greater difficulty. Here, a slight boost in brightness above the reference value can be observed, making the image sometimes too bright, especially in more demanding scenes. Although the Filmmaker mode is definitely the best choice in the Z95A, these aspects require refinement to fully exploit the potential of the television.

After calibration, the Filmmaker mode truly lives up to its name. The white balance for both HD and 4K HDR content has been significantly improved, resulting in more natural and consistent colours. The pink hues in HD content and the yellow tint in 4K HDR have been effectively eliminated, enhancing the realism of the image. As a result, the television now offers much better colour reproduction, positively impacting the overall viewing experience.

However, when it comes to brightness, the gamma curve now reveals a noticeable drop at the beginning, making the darkest details more difficult to discern. The EOTF curve for 4K HDR content remains largely unchanged and still falls short of the reference level, meaning the television continues to struggle with maintaining appropriate brightness. This issue is tied to the aggressive dimming algorithm, which affects overall brightness and black levels.

Despite the limitations associated with local dimming, the television has seen an improvement in colour reproduction quality. The Color Checker test results confirm that the colour samples are now much closer to the standards, resulting in a more natural and visually pleasing image.

After calibration, Panasonic Z95A shows its full potential, offering an almost perfect image. The television provides great adjustment capabilities, which we have fully utilized. The white balance after calibration is presented almost perfectly, and errors in SDR content at the level of 0.5 fall within an absolutely reference standard. The same is true for 4K HDR content – any pink tint on the screen has been completely eliminated, and the white balance is now exemplary.

The color palette and Colour Checker test confirm the excellence of the calibration. Errors below 2 is a result that will satisfy both professional calibrators and enthusiasts of cinema-quality images. Significant changes have also occurred in brightness characteristics – the EOTF curve has been leveled, eliminating previous issues with excessive image brightness. And the small error in gamma has been reduced.

Before calibration, the image was acceptable, but now it is a completely different league. It is a true feast for the eyes, the quality of which is hard to compare to anything else. Panasonic Z95A, after fine-tuning the settings, becomes a true master of color reproduction.

The smoothness of tonal transitions in lower-quality materials looks great – the Noise Reduction function effectively smooths tonal transitions while eliminating film grain. Although removing grain is not always desired, the final effect looks very aesthetic, especially for those who prefer a cleaner image.

As for upscaling, the Samsung QN900D demonstrates the enormous capabilities of the new AI technology processor. Photos and materials in lower resolution are upscaled while retaining many details – for example, a photo with a model looks great, devoid of unnecessary jagged edges, and the branches in the background are not overly aliased.

In the case of lower quality materials, the "Gradient Smoothing" function is responsible for smoothing tonal transitions. The best results are achieved with an intermediate setting – although they are not spectacular, the function works correctly and does not introduce unwanted effects into the image. It can be rated as average, but sufficient to improve the quality of tonal transitions.

As for digital processing, or upscaling, the image looks surprisingly good. It is vibrant and pleasant to the eye, making lower quality content, such as standard television or YouTube, look quite decent. However, minor issues can be noticed, such as "jaggies" on edges, e.g. branches in the background. Nevertheless, this does not significantly impact the overall viewing experience, and the television handles this material in an acceptable manner.

The Samsung QN900D is currently the fastest television in the world – quite literally. With an impressive refresh rate of 240 Hz at 4K resolution, it offers a remarkable performance that PC gamers will undoubtedly appreciate. Movie enthusiasts will also find much to admire, as Samsung provides a 10-level scale in the picture clarity settings, allowing for extensive image customisation. Users can choose whether they want the television to deliver a smoother, more fluid effect at the highest settings, or a more cinematic experience with visible frames at the lowest settings.

Panasonic Z95A, with its 144 Hz panel, offers excellent image smoothness. For films, there is the "Intelligent Frame Creation" feature, which enhances fluidity and reduces motion blur. The user has two sliders at their disposal: "Motion Blur Reduction" – responsible for clearer and sharper details in fast-moving scenes. "Film Smoothness" – adds smoothness by creating additional frames between the originals, making the motion look smoother and more natural with a "soap opera" effect.

As a result, viewers can adjust the settings to their own preferences. Films and less dynamic materials appear smooth and natural, which should satisfy most users.

The Samsung QN900D is excellent for console gaming, packed with features gamers will truly appreciate. It comes with 4 HDMI 2.1 ports, but they do not support the full 48 Gb/s bandwidth. However, for most users, this bandwidth is more than adequate. The TV also supports Auto Low Latency Mode (ALLM) and Variable Refresh Rate (VRR), which ensures smoother gameplay and eliminates screen tearing during fast-paced action. Features like G-Sync and FreeSync are also supported, enhancing compatibility with both consoles and PCs equipped with compatible graphics cards, helping to reduce stuttering and provide a smooth image.

A standout feature exclusive to Samsung is the Xbox Game Pass app, allowing users to stream games directly to the TV without needing an Xbox console. This is a very convenient option for gamers who want to enjoy their favourite games without purchasing additional hardware. The Samsung QN900D also features a Game Bar, which provides quick access to gaming-related settings, making it easy to configure the TV for optimal performance.

The Auto Motion Plus Game function offers a special motion smoothing mode that increases the frame rate (up to 4K@60Hz). Importantly, this does not raise input lag significantly, so players can enjoy smoother visuals without sacrificing responsiveness. With all these features, the Samsung QN900D is a top-tier choice for gamers seeking a television with the best possible specifications.

Panasonic Z95A this year shows that the manufacturer has made a huge leap forward in terms of support for gamers. The television offers practically everything one could expect from a device in this category. Support for ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate) ensures smoothness and no tearing in dynamic games. The 144 Hz panel allows for incredible fluidity, and the additional support for resolutions other than 4K provides greater flexibility, which is a significant plus for gamers using various setups.

Attention should also be paid to the unique and somewhat specific "Game Bar." Its intuitive interface stands out from the competition and allows quick adjustments to key settings such as VRR, brightness level, or picture mode without interrupting gameplay.

However, in this class of device, there is a slight disappointment – the Panasonic Z95A offers only two HDMI 2.1 ports, instead of four. This is definitely insufficient for a premium television, especially at a time when many people have more than one device requiring full HDMI 2.1 support, such as a next-gen console or a high-end computer. In this category, it is hard to accept, especially given the high aspirations of this model. Despite this, the television is an excellent choice for gamers, offering versatility and functionality at the highest level.
