Samsung DU7192 (VA) vs Hisense U6NQ

In the luminance charts, the peak brightness of the television is around 280 nits. Unfortunately, this value is too low to fully enjoy HDR effects, which require significantly higher luminance. In the tested materials, such as The Meg and Gemini Man, the lack of adequate brightness severely limits the magic of HDR, and the details in the brighter parts of the image are not sufficiently highlighted. For users primarily consuming SDR content, this level of quality may be acceptable, but it is definitely not enough when it comes to HDR. Additionally, the coverage of the DCI-P3 colour palette at 82% does not favour presenting HDR content in its full glory. The limited colour gamut makes it difficult for the television to reproduce vibrant and diverse colours, which is crucial for achieving a cinema-like experience.

Hisense U6NQ offers a stable HDR effect, which is a rarity in TVs with local dimming. On most streaming platforms, in films and series recorded in 4K, the television delivers consistent performance – in every tested scene, regardless of difficulty, the brightness is around 450 nits. This is a pleasant surprise, as in many models of this class, there are notable differences – some scenes are well-lit, while others are heavily dimmed by dimming algorithms. However, the Hisense U6NQ prioritises maintaining higher brightness, which comes at the expense of black levels, as mentioned in the contrast test paragraph.

The HDR effect on the U6NQ is satisfactory, offering a noticeable "burst" of light in bright moments, although it is worth noting the previously mentioned blooming, which may be visible in more challenging scenes. In terms of colours, the television also performs decently – the coverage of the DCI-P3 palette is 89%, and BT.2020 is 71%. Although these are not results that would impress more demanding users, for beginners in the world of high-quality materials, the U6NQ serves as a solid choice. Therefore, it presents an interesting proposition as an "entry-level" television for home cinema.

The best factory mode we relied on during testing turned out to be "Filmmaker". Although this mode is the closest to the creators' intent for films, it is not without certain imperfections. The white balance chart in both SDR and HDR clearly shows a dominance of red, resulting in significant yellowing, particularly noticeable in whites and on actors' faces. In HDR mode, there is also a slight dominance of green, which, however, does not have as much impact on the perception of the image. The gamma, which is responsible for brightness in SDR materials, performed quite well, but with one serious caveat. In the darkest parts of the image, it was too low, causing excessive brightness in those scenes, depriving the film of drama and contrast. For HDR, the white balance remains at a similar level; however, the EOTF curve chart draws attention. At the beginning, the curve clearly bulges, leading to a strong brightness in the darkest scenes. Then the result suddenly drops below the reference line, resulting in an overly dark image and a loss of dynamics in the brighter parts.

In summary, the "Filmmaker" mode, despite its advantages, requires refinement – especially regarding white balance and proper management of brightness in the darkest and brightest parts of the image. In its current form, it may be acceptable for less demanding users, but for viewers expecting precise image reproduction, it may leave much to be desired.

Hisense U6NQ in Filmmaker mode offers really decent colour reproduction, although it's worth noting that differences between individual units can be noticeable. The model we tested was pleasantly surprising, especially with HD content in SDR quality. The white balance was correct here, and errors around 3–4 ΔE should be acceptable for the average viewer. The television performed slightly worse with colour reproduction in 4K HDR materials. The dominance of blue shades led to unnatural cool tones on the Colour Checker chart, giving the image a "store-bought" character. Combined with issues in brightness characteristics – gamma and EOTF curve caused some parts of the image to be too dark – the Filmmaker mode loses some of its credibility in this case. Although the factory settings of the tested unit deserve praise, especially in SDR, there were still minor shortcomings that would require correction to fully exploit the capabilities of the television.

Even for its lower models, Samsung offers advanced image calibration tools, which allow for significant improvement of the factory settings. We undertook this task, and the results turned out to be more than satisfying. The white balance, which previously exhibited a strong yellowish tint in both SDR and HDR, was significantly improved. Although slight deviations from the norm can be noticed, the overall effect is much cleaner and more natural than before calibration. As a result, whites and skin tones look much better. We also managed to properly shape the gamma in SDR materials, which allows for achieving the maximum contrast that this television can offer. The EOTF curve, responsible for HDR materials, was also improved – the image is no longer brightened or darkened as drastically as it was before calibration. Despite these successes, HDR materials still struggle with high deltaE error values. The main reason lies in the limited brightness of the television, which does not allow for a complete representation of the dynamics of HDR content. Nevertheless, after calibration, the image is clearly better and more aligned with the creators' intentions. For users seeking the best possible quality in this class of equipment, calibration is definitely recommended.

Although the factory settings of the Filmmaker mode on the Hisense U6NQ were quite good, we decided to carry out a calibration to fully assess the capabilities of this model. Only after such an adjustment can one see how the television performs under ideal conditions. In the case of SDR content, which was already at a high level, we managed to further improve the white balance. However, the most significant change came from correcting the brightness characteristics – the gamma was optimised and no longer causes excessive dimming of the image, which improves its naturalness.

For 4K HDR content, the calibration also produced positive effects. We eliminated the blue dominance issue, resulting in a more balanced and natural image. However, managing brightness in HDR materials remains a more complex matter. The EOTF curve, while having problems with dimming the image in the 10–30% brightness range in laboratory conditions, reveals other shortcomings in real scenes. The television tends to excessively brighten the smallest elements on the screen. As a result, this leads to visible halo effects around bright objects. This phenomenon, which we mentioned earlier in the context of contrast and HDR, arises from the technological limitations of the particular model and is often difficult to eliminate.

In short: although the Filmmaker mode with factory settings performed decently, calibration allowed us to extract an even better effect – minor adjustments resulted in a more balanced image, especially in HDR content. For users seeking the highest quality picture, calibration will be a beneficial step.

The tonal smoothing function operates in two modes – "off" and "auto". Turning it off causes gradation issues, while the "auto" mode ensures smooth transitions, but at the cost of grain and detail, which are often blurred. Due to these limitations, we do not recommend using this feature, as confirmed by our tests conducted with it turned off.

Scaling of lower resolution materials in this model is not impressive. Details are blurred, and the edges of objects may contain artifacts. This limitation makes the television perform better with higher resolution content.

With high-quality materials, such as 4K, tonal transitions on U6NQ look really good – the colours blend nicely, and the image is coherent. Unfortunately, when we move to content in lower resolutions, the television does not offer any additional features that could improve this aspect. An example is the test with the light bulb, where it is clearly visible that the television has a problem with rendering subtle tonal transitions.

However, digital processing performs quite well. The image looks pliable, is pleasantly soft, and free from excessive banding. Moreover, thanks to the sharpness settings, it can be adjusted according to personal preferences – whether towards a softer or sharper image. Overall, although scaling lower quality materials could be better, the television handles image processing effectively.

Although the Samsung DU7192 is the lowest model in the manufacturer's range, it is equipped with motion smoothing technology. While the functionality of this solution is significantly limited compared to more expensive models, its presence alone distinguishes the television amidst competitors in this price bracket. The TV supports a maximum refresh rate of 60 Hz, which is sufficient for comfortable viewing of films and series, but may be inadequate for dynamic content such as sports. In the motion smoothing menu, we can find, among other things, the "Judder Reduction" feature. Unfortunately, its performance leaves much to be desired – regardless of the setting, the picture exhibits the characteristic stutter known from materials recorded at 24 frames per second, making this feature practically ineffective.

Hisense U6NQ offers native 60 Hz refresh rate at 4K resolution, but the manufacturer has added a feature that allows the refresh rate to be increased to 120 Hz, at the cost of reducing the resolution to Full HD. This solution, which we have seen before in TCL televisions, such as the C655 or C655 PRO. This gives the user the choice – higher motion fluidity or full resolution. This is a sensible approach, especially considering that many games on next-generation consoles do not achieve full performance in 4K at 120 Hz.

As for movies, the television is equipped with a motion smoothing feature that allows you to adjust the motion characteristics to your own preferences. This allows for a more cinematic effect or increased fluidity in dynamic scenes. Overall, Hisense U6NQ offers reasonable solutions in terms of motion fluidity that should satisfy both gamers and movie enthusiasts.

Samsung DU7192 is equipped with HDMI 2.0 ports, which is expected in this price range. This limitation means there is no support for the full capabilities of the latest generation consoles, such as VRR technologies. The television only offers a basic feature for gamers – automatic switching to low latency mode (ALLM), and support for basic HDR for games in the HGiG standard. HGiG allows for the display of HDR content in games according to manufacturers' guidelines; however, the limited brightness of the television does not allow for full enjoyment of the effects that this standard offers. Unfortunately, there is a lack of conveniences such as GameBar, which is increasingly found even in cheaper models and greatly facilitates quick adjustment of settings for games. The presence of this feature could significantly enhance user comfort, especially for those who frequently change display modes.

Hisense U6NQ offers the option to choose between 4K at 60 Hz and Full HD with a refresh rate of 120 Hz. This solution may appeal to gamers who want to decide what is more important to them – higher resolution or smoothness. The television supports features such as ALLM and VRR, which help in achieving smoother gameplay. A nice addition is the GameBar – an easy-to-use panel that allows you to quickly change picture settings and check statistics. There is also a Dolby Vision Game mode, which operates with low input lag, which is a big plus for console enthusiasts. Unfortunately, it lacks HGiG, which could further enhance HDR quality in games. Nevertheless, the Hisense U6NQ performs quite well as a gaming television, especially for those who play occasionally and do not require the highest refresh rates in 4K. It is a solid choice for less demanding users.
