SAMSUNG OLED S95F (QD-OLED) vs Hisense U7S Pro

The new generation of QD-OLED matrices in the Samsung S95F shows its full potential, with brightness results that are truly stunning. In test film scenes like "Life of Pi" or "Sicario 2," where smaller light elements appear – stars, the moon, or headlights – the television managed to achieve over 2000 nits of brightness. This is a result that surpasses even most top-of-the-range Mini-LED models.

The secret lies in the technology itself – instead of a limited number of dimming zones like in Mini-LED televisions, here we have millions of emitting pixels, allowing the television to fully showcase its power without technological compromises. Of course, as this is still an organic panel, in full-screen scenes flooded with white – like in the final sequence of the film The Meg – the brightness drops to around 1400 nits. Nevertheless, the result remains excellent and clearly exceeds what any OLEDs, both QD-OLED and WOLED, have offered so far. The colour reproduction is also particularly noteworthy. Thanks to QD-OLED technology, the television achieves nearly 100% coverage of the DCI-P3 colour space and about 80% in BT.2020. These values make HDR images not only dazzling in brightness but also captivating in the richness of colours.

Let's start with the fact that the U7S Pro is an impressively bright television – in calibrated mode, our measuring equipment indicated a staggering 2200 nits of peak brightness! This is an absolutely remarkable result, considering that this model is positioned rather as a mid-range option.

However, as we know, peak brightness on test patterns is one thing, and actual film scenes are another. Unfortunately, in real video materials, the backlight power clearly drops. Although in the most demanding moments, the television can still exceed the 1000-nit barrier – which is still an excellent result, perfectly aligned with the mastering standards of most HDR films – the real challenge comes from the aggressively tuned local dimming algorithms. Because of this, small, bright details such as stars or the moon in the night sky are noticeably dimmed. The television tries at all costs to maintain deep blacks, which is of course understandable, but unfortunately, this comes at the expense of the dynamics and brilliance of the HDR effect itself.

One must commend the colour reproduction. The new U7S Pro is a QLED design that provides very wide coverage of the colour palette. Unlike last year's model (U7Q Pro), this year's variant is a "true" QLED, rather than a solution based on a PFS filter. As a result, the colour saturation has clearly increased, and coverage of the most demanding BT.2020 colour space has surpassed the 81% barrier.

The best picture mode straight out of the box is undoubtedly Filmmaker Mode – a mode that Samsung has been using for several years, designed to faithfully convey the creators' intent. In SDR content, its implementation is not bad, although some imperfections can be observed. The image is slightly dimmed, and the screen has a subtle pinkish tint due to the dominance of red and blue in the white balance. Colour errors were maintained at a level of 3–4 ΔE units – and for those who are not familiar: a value above 3 is the threshold at which the average human eye starts to notice differences.

However, much greater problems arise in HDR content. Here, the white balance was not such a significant issue – a slight excess of blue did not significantly hinder the viewing experience. The problem became managing brightness. In practice, the television "blasted" the image too much, causing details in the blacks to completely disappear. The final effect was far from expected, and colour errors in this mode became quite pronounced. It's hard to say why such a design decision was made, but it was evident that the factory HDR settings did not allow this television to showcase its full capabilities.

We tested the U7S Pro model – as we always do – in the best factory-calibrated picture mode, namely Filmmaker Mode. We can evaluate the displayed colours in two ways. The most disappointing was the profile designed for viewing SDR content, that is, traditional television, YouTube, and other less demanding materials. The picture was clearly yellowed, which turned out to be a direct consequence of a poorly set white balance. As our graphs show, there is a significant deficiency of the blue component, which drastically affected the overall colour temperature. This is clearly visible on the ColorChecker charts as well as on the graphs of the colour palette itself, where most samples leaned towards yellow. Fortunately, the factory HDR mode fared much better – there, the colour errors were around a Delta E value of 3, which is already a really solid result.

After calibration, it was possible to make subtle adjustments to the white balance and significantly improve the image characteristics. In SDR content, the quality has become practically reference-level – most colour errors have fallen below a ΔE value of 1, which is the level at which the human eye can no longer discern differences. This is a result that places the S95F among the very best televisions available on the market.

In HDR materials, the calibration also brought about a significant improvement. The television's tendency to blow out highlights has been brought under control, as confirmed by the analysis of the EOTF curve. A slight tendency to brighten the entire scene or occasional loss of detail in blacks can still be observed, but this does not significantly affect the overall perception. After calibration, the S95F reveals its full potential and can be described as one of the best televisions on the market!

We know, however, that the company Hisense is capable of much more – as previous generations have demonstrated – which is why we couldn't simply overlook the factory shortcomings of the U7S Pro model in everyday content. As is often the case, the television underwent professional calibration. The conclusions? This process brought about a colossal change. After manually adjusting the white balance and supplementing the deficiencies in the blue component, the annoying yellow tint disappeared as if by magic. White became naturally pure, and skin tones gained the appropriate, healthy hue. Importantly, calibration not only tamed the capricious SDR mode but also allowed us to extract the maximum potential from the panel, reducing average colour reproduction errors to levels nearly imperceptible to the human eye. The only thing we must criticise after the whole process is the very nature of the Mini-LED backlight and its specific interaction with the HDR signal. The aggressively tuned local dimming algorithms significantly interfere with the EOTF brightness curve. As a result, the backlight does not always work perfectly with the creator's intention – depending on the scene being viewed, the curve can noticeably deviate either above or below the reference, which at times disrupts the ideal dynamics of HDR imagery.

The Samsung S95F offers a noise reduction feature that is responsible for smoothing tonal transitions. It works very effectively, but in practice, it can be overly aggressive. Materials of lower quality – e.g., older recordings or videos from YouTube – become soft and plastic when this feature is activated, resembling an image digitally smoothed in a graphic program. Unfortunately, the natural film grain, which often adds authenticity to the image, disappears in the process. Fortunately, the television does not lose too many fine details, such as in skin textures or elements of the surroundings. Therefore, this feature is best used with discretion – depending on preferences, one can achieve a smooth image that is less natural, or one that is truer to the original. In our opinion, the most universal choice is the “Standard” setting.

The image scaling performs significantly better. The television handles materials of lower resolution well – even content at 576p looks quite decent, although a slight blockiness can be noticed. Overall, the effect is very good, although it somewhat falls short of what Sony Bravia 8 (II) or LG G5 can achieve. It is also worth mentioning a minor imperfection of the S95F – in older materials, overscan may occur, causing a slight trimming of the left edge of the image.

The digital processing of lower quality signals is at a very high level here, thanks to the MediaTek Pentonic 800 processor used in the U7S Pro. The upscaling performance is equally impressive, meaning the television’s ability to enhance lower resolution signals to 4K. We did not notice any unnatural, sharp contours on the screen, and our test image featuring the model simply looked attractive.

The Samsung S95F shows phenomenal performance in terms of motion fluidity. The panel operates at a native resolution of 4K with a refresh rate of up to 165 Hz, and combined with QD-OLED organic technology, it delivers incredible results. Sports and games look stunning – the image is fast, dynamic, and very natural. Additionally, the built-in motion smoother and motion blur reduction system allow you to tailor the character of the picture to your own preferences. You can opt for a more "frame-like" effect with visible film structure or a smooth, theatrical spectacle. Every viewer will find a setting that suits them.

The Hisense U7S Pro uses a panel with a maximum refresh rate of 165 Hz in 4K, and in game mode, it can reach up to 330 Hz at Full HD resolution. However, it is important to remember that these highest figures do not significantly matter in everyday use, as most content is still limited to a maximum of 120 Hz (for example, when gaming on a console). Nevertheless, the television handles motion quite well and performs really decently for an LCD construction.

There is little to criticise about the fluidity itself. In the menu, we find a motion smoother called "Motion Enhancement", which hides two sliders: blur reduction and judder reduction. These allow for manual configuration of the smoother, which works well in both films and sports, effectively enhancing the raw television signal.

The advantages of low motion blur and excellent motion fluidity characteristic of OLED panels are just the beginning, as the Samsung S95F has been designed with gamers in mind. The manufacturer has equipped it with four HDMI 2.1 ports – although limited to a bandwidth of 40 Gb/s, in practice this has no impact on compatibility with consoles or PCs. We get a full suite of gaming features: variable refresh rate (VRR), automatic game mode (ALLM), as well as a very well-implemented HGiG standard, which ensures that HDR titles look exactly as their creators intended. Completing the package is the Game Bar – a clear settings hub where we can preview and change all key image parameters with one motion. The proprietary motion smoother, Game Motion Plus, also deserves commendation, as it can smooth out animations, which is particularly useful in productions running at 60 frames, where stability is not always exemplary. While support for Dolby Vision in games is lacking, it’s hard to view this as a serious drawback – Samsung compensates with other solutions. This is one of the best, if not the best, gaming televisions available on the market today.

If you plan to connect a console or PC to the U7S Pro, you will be more than satisfied – this television is excellent equipment for a gamer. Hisense has not spared any expense and has included as many as 4 HDMI 2.1 ports with full bandwidth of 48 Gbps. You won’t need to juggle cables as each port will handle the full set of features. We have an automatic game mode (ALLM) and VRR, which operates in a wide range from 48 Hz to an impressive 330 Hz. Of course, that 330 Hz is currently a gimmick for owners of powerful PCs, as consoles will be limited to 120 Hz, but it’s good to have that buffer for the future. The Game Bar also works very well during gaming. It’s a handy menu bar for gamers, where you can quickly change the picture mode, enable a crosshair in the centre of the screen, and even change the display aspect ratio to ultra-wide without having to exit to the main television settings, which will be appreciated by fans of PC simulators. The only downside worth mentioning is the improper implementation of the HGiG format in games. The issue is that the television ignores instructions from the console regarding the image generated in HDR10 and continues to forcefully interfere with the image it produces, trying to "enhance" it in its own way. This makes proper HDR configuration in the console menu (where you set brightness on symbols/checkerboard) somewhat difficult.
