Samsung OLED S95D vs Hisense U8NQ

Samsung S95D offers excellent HDR performance, delivering consistent effects across all scenes exceeding 1500 nits, except for the fifth, where brightness drops to 800 nits. Despite this, the TV maintains a high level of picture quality. A significant advantage of QD-OLED technology is the ability to maintain high brightness even in the smallest elements on a black background, which is rare in LCD and mini LED TVs. As a result, every scene impresses with strong lighting effects, regardless of the size of the illuminated surface. Only in the brightest scenes with a large light area does brightness drop slightly, which is typical even for standard LG OLEDs. Additionally, the quantum dot coating has allowed for an unprecedented high coverage of the BT.2020 colour palette at 88%.

Hisense U8NQ demonstrates its capabilities in HDR, achieving a luminance score on the chart exceeding 2000 nits. In the first, third, and fifth scenes where the screen is covered in light, the television showcased very high brightness, which is impressive and allows you to enjoy the full effect of HDR. Unfortunately, in the second and fourth scenes, such as those from the film "Sicario 2," the television encounters issues maintaining brightness, resulting in disappointing scores around 250 nits. Although the large number of dimming zones should theoretically help, the algorithm responsible for their control does not always work perfectly—bright, small elements like the moon or helicopter lights are too dimmed, which takes away from the typical HDR effect. Instead of blinding brilliance, we receive a more subdued light that does not convey the full potential of HDR. Nevertheless, the television deserves commendation for its very good coverage of the DCI-P3 colour gamut at 97%. This makes colours vibrant, and most movie scenes look really good, significantly enhancing the viewing quality.

On the Samsung S95D, the best colour reproduction mode is the Filmmaker mode. We conduct all our tests in this mode. Although initially, the image in this mode may seem a bit warmer to the viewer, it provides significantly more detail compared to the standard or dynamic modes, which are always oversaturated and artificial. Therefore, Filmmaker is the most closely aligned with the vision of filmmakers and ideal for watching high-quality content. It is worth noting, however, that the factory settings are not perfect, despite dealing with premium segment equipment. The image may contain certain issues that affect the overall quality of the displayed scenes. An example is the drops in red colour in the white balance, both in HD and HDR content. Colour Checker tests showed that the colours lean towards cooler tones. The image is dominated by blue hues, and the overall colour spectrum is distorted. As can be seen in the picture below, the boy from the film appears in cooler tones, making him look less natural. When it comes to brightness characteristics for HD content, it is quite accurate, although there are minor errors. The biggest issue arises when displaying 4K HDR content. The EOTF curve, which seems appropriate at first glance in test patterns, in actual film scenes shows that the TV sometimes "messes around" with the image. This results in some scenes appearing slightly brighter and others darker.

Samsung S95D offers quite decent factory colour reproduction; however, it has some shortcomings that may require calibration to fully utilise the potential of this television. The process is recommended to achieve the most natural and immersive image possible.

The Filmmaker mode on the Hisense U8NQ television can be described as the most accurate mode present in this model. Despite its accuracy, it has significant errors in reproducing the reference image, which we will describe now. In the case of HD content, the white balance shows a distinct dominance of red, causing the image to appear overly pinkish and warm. In the comparison photo below, you can see how this effect impacts the presentation of content. The brightness characteristic also leaves much to be desired—a too low gamma causes the screen to be excessively brightened, and blacks appear washed out, making the overall image seem cooler than it should be.

For 4K HDR content, the problem is the opposite—the white balance shows too much dominance of blue, making the image take on an artificial quality and seem unnaturally sharp. All these deviations for both HD and 4K HDR content can be confirmed using the Colour Checker test, which clearly shows how the colours deviate from the correct patterns.

How much can the picture quality of a TV change after calibration? After calibration on the Samsung S95D, the white balance has significantly improved, eliminating all major errors, allowing for a more natural and harmonious colour representation. In the case of 4K content, there are only minor imperfections which do not affect the overall picture quality. Thanks to the calibration, viewers can now enjoy more balanced tones, which better reflect the intentions of filmmakers. The contrast has also improved, and the gamma shows even better results. This means that the differences between bright and dark parts of the image have become more pronounced, resulting in better depth and detail of scenes. As a result, shadows have gained more detail, and bright areas are no longer so overwhelming, providing a more realistic visual experience. However, it should be noted that the EOTF curve is slightly below the expected level, which may affect how the TV handles dynamic scenes. Nevertheless, after calibration, the overall picture quality has significantly improved, and viewers can now enjoy a visual experience that is more in line with the creators' intentions. The TV handles subtle tonal transitions and contrast better, making it more suitable for watching movies and high-definition programs. Ultimately, the picture after calibration is closely aligned with reference quality, making the visual experience even more satisfying.

The white balance for both 4K and HD content has been heavily adjusted, significantly improving the image quality. While some errors are still visible, they are not large enough to greatly affect the perception of the image. A notable improvement can also be seen in the gamma brightness characteristic — the image is no longer excessively bright, resulting in more natural blacks and better contrast.

However, like with many other Hisense models, there are noticeable issues with the EOTF curve, which is responsible for managing brightness in high-quality materials. Although it may seem correct at first glance, when the filter is applied to the "EOTF in films" chart, it is evident that the TV is somewhat "playing around" with 4K content. It is clear that the EOTF curve is significantly below the reference level, leading to an overall dimming of the image compared to the reference. We noticed this effect in previously tested scenes from the films "Pan" and "Billy Lynn." While it is not a serious issue, it is worth paying attention to. It could be significant for those seeking a display with the most faithful image reproduction. Despite this error, the image will be more enjoyable for most. Colours are represented better, and the overall image quality is significantly improved.

How does the television handle tonal transitions in lower quality materials? Generally speaking, the S95D performs exceptionally well. On the screen with the light bulb, there are virtually no transitions between shades of grey, making it one of the best televisions we have tested in this regard.

When it comes to digital processing, the entirety of the image — from branches to the models' characters — has been well rendered, with no jagged edges or overly visible contours. However, we must point out one issue: the image has been slightly cropped. Nevertheless, the television performs brilliantly, and details in lower quality materials are still noticeable and well-defined.

In the context of smoothing tonal transitions, the Hisense U8NQ unfortunately struggles. The "Smooth and Gradient Picture" feature does not yield noticeable effects — there is no improvement in any setting, which is disappointing, especially in demanding scenes with a lot of subtle tonal transitions.

As for the digital processing, or so-called upscaling, the scene with the model is rendered correctly — her outline is clear, without significant cropping. Similarly, thin lines, like tree branches, have slight jaggedness, but the overall image looks plastically and softly, providing a good impression. Unfortunately, there is also an issue with so-called overscan, which results in cropping of the image at the edges. This can be annoying when watching content such as news, where the bottom information bars may be partially invisible.

The Samsung S95D TV, equipped with a 120 Hz refresh rate panel (and even up to 144 Hz in the appropriate PC configuration), provides excellent motion fluidity. Samsung offers a variety of image sharpness settings on a ten-point scale, allowing users to adjust the display according to their own preferences – whether the picture should be more cinematic/frame-like or more theatrical/smooth. In tests with UFO, the OLED panel shows its advantages, eliminating any blurring. The lightning-fast pixel response ensures that dynamic movements are rendered with unparalleled precision.

Hisense U8NQ is equipped with a 144 Hz panel, making it an excellent choice for both sports and gaming. The TV will also satisfy movie fans, as it features a built-in "Ultra Motion Smoothness" enhancer that allows users to control the smoothness of the image — you can choose whether you prefer a more "framey" picture or a smoother, cinematic effect. This provides great flexibility in adjusting the motion quality to individual viewer preferences.

The Samsung S95D television is perfectly adapted to the needs of gamers, offering four HDMI 2.1 ports that support key features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HDR Gaming Interest Group (HGIG). The HDMI 2.1 ports do not offer the full 48Gb bandwidth, but they are still sufficient for achieving the appropriate resolution and smoothness. With these technologies, gamers can enjoy smoother and more responsive gameplay, which significantly impacts comfort and performance during intense gaming sessions. One of the biggest advantages is the Xbox app, which allows for cloud gaming without the need for a console. With it, gamers can access a wide range of titles directly on the television, enjoying high image quality and smooth gameplay. Additionally, the S95D offers a Game Bar feature that enables easy management of game settings, including quick adjustments to parameters such as changing the aspect ratio, which can be extremely useful in various games and game modes. It is also worth mentioning the support for G-Sync and FreeSync, which is a huge plus for users of Nvidia and AMD graphics cards. Despite the lack of support for Dolby Vision, the television still offers excellent features that make it an ideal choice for console gaming enthusiasts. Overall, the S95D combines modern technologies with superb image quality, creating a complete package for every gamer.

Hisense U8NQ offers everything a player might need for comfortable gameplay. The television supports a refresh rate of 144 Hz, ensuring an incredibly smooth image, especially in dynamic action games. The VRR (variable refresh rate) feature allows the image to adjust to variable frames per second, eliminating stuttering and tearing, translating to exceptionally smooth gaming. Additionally, the television is equipped with the ALLM (auto low latency mode) feature, which automatically switches the TV to game mode, minimising input lag. This means players can enjoy responsive gameplay without needing to manually adjust settings.

Hisense U8NQ also supports Dolby Vision, which is important for gamers who value high image quality, high contrast, and deep colours in games that support this format. The television also features a "Game Bar" — a function that allows quick access to essential settings during gameplay, significantly enhancing user convenience.

However, it is worth noting that despite its rich set of features, the Hisense U8NQ does not offer support for the HGiG standard, which is a popular HDR format in gaming. This may be disappointing for players expecting optimal detail reproduction in HDR scenes. Nonetheless, the other features of the television make the Hisense U8NQ a solid choice for console gaming enthusiasts, offering fluidity, high contrast, and user convenience.
