Hisense U8NQ vs Samsung Q8F

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.

In terms of brightness, the Samsung Q8F performs surprisingly well for a television without local dimming. It measures up to 500 nits, which practically means that most movie and series scenes look pleasant, and it definitely cannot be accused of lacking the "HDR effect." In films like Life of Pi or The Meg, the screen was able to glow and deliver light effects at a satisfying level. It struggles more during challenging moments—with dark frames containing single bright points. The global dimming used causes the television to darken the image to maintain deep blacks, but at the cost of detail brightness. This is clearly visible in the scene from Sicario 2, where the helicopter lights dropped to around 200 nits. This is a conscious design decision that gives the impression of deeper blacks but somewhat takes away from the brilliance of individual elements, and this should simply be kept in mind. When it comes to color reproduction, the Q8F utilizes quantum dot technology, which broadens the color range. A DCI-P3 coverage of 91% can be considered a decent result, although it is not a record-breaking achievement compared to other QLEDs.

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.

We decided to check the Filmmaker mode because it provided us with the best picture right out of the box. However, this does not mean it was perfect. The white balance had too much blue and red tint, causing the white to take on a slight purple-pink hue. Such an imbalance affected the visibility of practically all colors, as can be seen in the comparison photo below. The brightness characteristic in SDR content was quite well adjusted, although in HDR materials, we noticed that the television did not always manage its global dimming—at times, the screen was too dim, while at other times it suddenly brightened. Fortunately, issues related to colors can be effectively corrected with calibration tools, so we decided to get to work.

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 calibration, we managed to correct the white balance almost to perfection. Older SDR content looks stunning — most errors are within a threshold of 2, which is definitely below the human eye's perception limit. In HDR, we also brought the white balance to the correct level, but a different problem arises here. So why are there still relatively large errors in color reproduction? This is mainly due to the limited color palette and the way the television manages brightness. The applied global dimming technique does not give the user control in the settings, so when analyzing the EOTF curve in HDR films, it is clear that the Q8F can independently modify luminance. This can be considered a certain limitation, but despite this, the image after calibration is still much more enjoyable than in the factory version.

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.

Let's see how the Q8F handles older content, which often has poor quality. Let's start with the positives: the upscaling, which means raising the image to a higher resolution, works really well. The TV handles both classic television and materials from YouTube without giving the impression that we are dealing with something completely unattractive. Materials in very low resolutions, such as 576p, perform worse — the image can be cropped, and unfortunately, the overscan phenomenon cannot be turned off. However, the digital processing itself looks worse too. The noise reduction function, instead of removing unwanted interference, smooths out almost everything: film grain (which is desirable for many viewers) disappears along with the texture of the image, and the faces of the actors begin to resemble characters from cheap Turkish soap operas. It is therefore hard to consider this option useful — it's best to leave it completely turned off. Perhaps Samsung will refine the operation of this feature in updates, but for now, it’s difficult to regard it as anything other than an unnecessary addition.

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.

Due to the 60 Hz panel, it's hard to call the Q8F a television made for gaming or watching sports. The panel isn't particularly fast, making motion blur clearly visible. If you were counting on spectacular, almost "stadium-like" experiences during broadcasts, you might feel a slight disappointment. Fortunately, in the case of movies and series, Samsung has not abandoned motion smoothing features. This is nothing other than a motion smoother that allows improving the fluidity of productions recorded at 24 or 30 frames per second. Thanks to this, one can decide whether they prefer a smoother, "television" image or to maintain a cinematic quality. It all depends on the viewer's preferences, and the ability to adjust this parameter is undoubtedly a plus.

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.

[UPDATE] We have updated our 2025 Samsung TV reviews following the release of firmware version 1131, which officially restores the essential HGiG (HDR Gaming Interest Group) support.

It is not entirely clear what Samsung has mixed up this year with its televisions, but the Q8F is not free from all the confusion with updates and shortcomings. While its older cousin, the Q67D, could still be recommended to casual gamers with a clear conscience, it's hard to find a reason to do so here. Aside from the automatic game mode and the attractively designed Game Bar, we practically get nothing that could attract gamers. The lack of proper HGiG implementation is a big problem, especially since function simply disappeared after the 1126 update. The issue with VRR is even worse. Although it is featured in the manufacturer's brochures and appears in the Game Bar, we couldn't activate it. The Xbox Series X console did not allow it to be activated at all, and the option remained grayed out and inactive. It's hard to praise such a television even to casual gamers, which is a shame because Samsung has had a strong bargaining chip in the gaming segment for years.
