Hisense U8NQ vs Samsung S85F (WOLED)

Hisense U8NQ showcases its capabilities in HDR, achieving a brightness level on the luminance chart exceeding 2000 nits. In the first, third, and fifth scenes where the screen is covered in light, the television displays very high brightness, which impresses and allows one to enjoy the full effect of HDR. Unfortunately, in the second and fourth scenes, such as those from the movie "Sicario 2," the television encounters issues maintaining brightness, resulting in disappointing results around 250 nits. Although a large number of dimming zones should theoretically help, the algorithm responsible for their control does not always perform perfectly—bright, small elements like the moon or helicopter lights are too dim, which detracts from the typical HDR effect. Instead of dazzling brightness, we get a more subdued light that does not reflect the full HDR potential. Nevertheless, the television deserves praise for its very good coverage of the DCI-P3 colour palette at 97%. As a result, colours are vibrant, and most movie scenes look really good, significantly enhancing the viewing quality.

For most of the time, let's say in 90% of film scenes, viewers won't see practically any difference between the S85F versions. When small but very strong light points appear on the screen – a lantern in a dark alley, a gunshot, the sun breaking through the clouds – this WOLED panel (like the smaller S85F) performs wonderfully. Our measurements showed peak brightness at around 750 nits. We can confidently state: this is an excellent result that guarantees fantastic HDR effects. The problem arises in a very specific, uncomfortable situation for any OLED. We're talking about the moment when the entire screen has to shine at full power brightly. Examples include a slide with a white background, a ski jump scene, or our test sequences (5) from the movie The Meg. And here, unfortunately, the results diverge quite significantly to the detriment of the WOLED panel variant. Our measurement equipment was able to measure a maximum of about 250 to 300 nits of brightness in such conditions. Just to be clear: the same model on a QD-OLED panel in the same test is almost twice as bright. The second issue: colors. And here we also have to be honest – QD-OLED has a design advantage. Why? It’s simple. QD-OLED creates colors from three components (red, green, and blue) and does not need an additional white subpixel. The WOLED panel we are testing uses this white subpixel mainly to boost overall brightness. The effect is that QD-OLED is able to show a slightly wider color palette, and the colors are a bit "cleaner." But let’s be clear: it’s not that the colors on this WOLED panel are bad! On the contrary, they are actually very good. Coverage of the DCI-P3 film palette at 97% and 71% for the wider BT.2020 palette is still a high standard. We just have to honestly admit that this few percent advantage in color coverage is on the side of QD-OLED technology and may be noticeable in very specific moments.

The Filmmaker mode on the Hisense U8NQ TV can be described as the most accurate mode available 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 clear dominance of red, making the image overly pink and warm. The comparative photo below illustrates how this effect influences content presentation. The brightness characteristics also leave much to be desired — too low gamma causes the screen to be excessively brightened, and blacks look lightened, making the overall picture seem cooler than it should be.

In the case of 4K HDR content, the problem is reversed — the white balance shows too much dominance of blue, resulting in an artificial character to the image and making it appear unnaturally sharp. These deviations for HD and 4K HDR content can be confirmed with the Colour Checker test, which clearly shows how colours deviate from the correct patterns.

When it comes to factory color reproduction, our test sample in SDR mode suffered from a slight deficiency in red and yellow color. This resulted in a subtle yellowish tint visible in the shades of white. However, this is not the biggest problem with the S85F. Similar to the QD-OLED panel variant, the biggest issue with this model is the way it presents HDR content. When we look at the EOTF curve graph, it is easy to see that the television has quite significant problems with overly brightening the image. This causes the final picture in many scenes to become very unnatural.

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

However, as with many other Hisense models, there are visible issues with the EOTF curve, which is responsible for managing brightness in high-quality materials. Although it may seem correct, once the filter is applied on the "EOTF in movies" graph, 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 movies "Pan" and "Billy Lynn." While it is not a serious problem, it is worth mentioning. It may be of great importance to those looking for a display with the most accurate image reproduction. Despite this error, the image will be more enjoyable for most. Colours are better reproduced, and the overall image quality is significantly improved.

After calibrating in Filmmaker mode, we managed to eliminate most of the unwanted effects. In SDR content, the television performs exemplary, and its color reproduction errors do not exceed a value of 2, which is an excellent result. A bit worse, although still very good, are the HDR quality contents. While we were able to eliminate a significant unnaturalness in the image caused by too high a positioning of the EOTF curve, the most discerning observers may notice that it is not perfectly aligned. It runs slightly below the reference curve, which would suggest that the S85F has slight issues showing all the details in the image. We must point out right away that it is highly unlikely that an average viewer would notice any shortcomings in the image. The final effect after calibration is rated as exemplary.

In the context of smoothing tonal transitions, the Hisense U8NQ television unfortunately does not perform well. The "Smooth and Gradient Image" function does not produce noticeable effects — there is no improvement in any setting, which is disappointing, especially in demanding scenes with subtle tonal transitions.

As for digital processing, or the so-called upscaling, the scene with the model is presented correctly — its outline is clear, without significant cropping. Similarly, thin lines, such as tree branches, have slight jaggedness, but the overall appearance is plastic and soft, which creates a good impression. Unfortunately, there is also an issue with the so-called overscan, which causes cropping of the image at the edges. This can be annoying when watching content such as news, where the lower information bars may be partially invisible.

The processing of tonal transitions (gradients) in the S85F is at a high level. The television effectively handles posterization (the "stepping" effect of colors), even with heavily compressed materials, such as from streaming services. However, using this feature requires making a certain compromise. We noticed that the noise reduction algorithm is quite aggressive – even at the lowest setting, it can eliminate natural film grain, which for many viewers is part of the film's aesthetics. The "Standard" setting seems to be the golden mean, not causing visible loss of important details, so we can recommend it. However, we advise against using the "High" level, which removes not only noise but also desired details, such as texture or structure of objects on the screen.

The scaling (upscaling) process of lower resolution content works very well in the S85F. The image is sharp and clear. The only minor imperfection we observed is occasional, slight aliasing on the edges. The television also still exhibits characteristics typical of this manufacturer, such as active "overscan" (slight magnification of the image). This should be kept in mind, especially when watching older materials, as it may result in a minimal cropping of the original frame.

Hisense U8NQ is equipped with a 144 Hz matrix, making it a great choice for sports and gaming. The television will also easily satisfy movie fans, as it features a built-in "Ultra Motion Smoothness" processor that allows you to control the fluidity of the image — you can decide whether you prefer a more "framey" look or a smoother, cinematic effect. This provides great flexibility in adjusting the quality of motion to the individual viewer's preferences.

The S85F is a model with impressive speed. The use of a 120 Hz OLED panel ensures that dynamic scenes, both in games and during sports broadcasts, meet expectations: smoothly, sharply, and without loss of clarity. A key role here is played by the instantaneous pixel response time, which is a natural advantage of OLED technology. Transitions between frames are instantaneous, and the image remains clear even during the fastest camera movements. Moving objects, like a ball on the field or a car in a chase scene, are clear and devoid of the characteristic motion blur typical of LCD panels (the so-called "tail").

Hisense U8NQ offers everything a gamer may need for comfortable gameplay. The TV supports a refresh rate of 144 Hz, which ensures an incredibly smooth picture, especially in dynamic action games. The VRR (variable refresh rate) feature allows for adjusting the image to varying frames per second, eliminating stuttering and tearing effects, resulting in an exceptionally smooth gaming experience. Additionally, the TV is equipped with the ALLM (automatic low latency mode) feature, which automatically switches the TV to game mode, minimizing input lag. This allows gamers to enjoy responsive gameplay without manually adjusting the settings.

Hisense U8NQ also supports Dolby Vision, which is important for gamers who value high picture quality, high contrast, and deep colours in games that support this format. The TV also has a “Game Bar” — a feature that provides quick access to essential settings during gameplay, significantly enhancing user convenience.

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