Samsung QLED Q70D / Q74D / Q77D vs Hisense U6NQ

The brightness of the Samsung Q70D is fairly average, yet it delivers a noticeable HDR effect. With brightness exceeding 400 nits, the distinction between SDR and HDR materials becomes evident. As observed in the discussion about contrast and black levels, the TV's performance varies across different scenes. In a scene featuring a bright sun against a darker foreground, the measured luminance is lower. However, in a scene with a large, bright light source dominating the frame, the TV achieves its peak brightness, reaching nearly 500 nits—a commendable result for its price range and display class.

Despite these strengths, the relatively low coverage of the wide DCI-P3 color gamut occasionally results in less vivid color reproduction. Even so, the TV offers rich colors and precise shade reproduction, enhancing the movie-watching experience. Furthermore, the Q70D excels in motion blur elimination during dynamic scenes, making it a solid choice for enjoying sports broadcasts and gaming.

Hisense U6NQ offers a stable HDR effect, which is rare in TVs with local dimming. On most streaming platforms, in movies and series recorded in 4K, the TV presents consistent performance – in every tested scene, regardless of difficulty level, brightness is around 450 nits. This is a pleasant surprise, as many models in this class show significant differences – some scenes are well-lit, while others are heavily dimmed by dimming algorithms. However, Hisense U6NQ prioritizes maintaining higher brightness, which comes at the expense of black levels, as mentioned in the paragraph about contrast testing.

The HDR effect on the U6NQ is satisfying, offering a noticeable "hit" of light in bright moments, although it is worth remembering the previously mentioned blooming, which can be visible in more challenging scenes. In terms of colours, the TV 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 content, the U6NQ serves as a solid choice. Thus, it presents an interesting option as an "entry-level" TV for home cinema.

The best factory mode on the Samsung Q70D is "Filmmaker," and it is the one we used when conducting various tests. Before the calibration process, it had several flaws that effectively prevented the conveyance of the director's intentions. In both SDR and HDR materials, the white balance was dominated by red and green colors. As a result, there was a characteristic yellow tint on the image, causing whites to appear yellowed and creating issues with skin tones, which were noticeably too warm. The reduced gamma in the standard color gamut materials caused a significant drop in the already low contrast. This resulted in an emphasis on details in the blacks but also in blown-out images in brighter scenes. The EOTF curve, in this case, turned out to be much better and only lightened those scenes with relatively low luminance. This was clearly visible in the section where we measured the maximum brightness of the television in HDR materials. At that time, the frame from the movie "Billy Lynn" was unnaturally bright and lacking depth.

The Hisense U6NQ in Filmmaker mode offers truly decent colour reproduction, although it is worth noting that differences between individual units can be noticeable. The model we tested surprised us positively, especially with HD content in SDR quality. The white balance was correct, and errors around 3–4 ΔE should be acceptable for the average viewer. The TV performed slightly worse in colour reproduction with 4K HDR materials. The dominance of blue hues led to unnatural cool tones on the Colour Checker chart, giving the picture 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 adjustment to fully leverage the capabilities of the TV.

Fortunately, Samsung provides a wide range of calibration tools in all its televisions, where we can find 2-point and 20-point grayscale adjustments as well as advanced CMS. Thanks to this, we were able to significantly improve the quality of SDR and HDR materials. The vast majority of errors have been corrected, and the image that the Samsung Q70D now generates is definitely closer to the reference. Higher deltaE errors in the high dynamic range materials are primarily due to the display's insufficient luminance.

Although the factory settings of the Filmmaker mode on the Hisense U6NQ were quite good, we decided to carry out calibration to fully assess the capabilities of this model. Only after such an adjustment can you see how the TV performs in 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 biggest change came from the brightness characteristic correction - gamma was optimized and no longer causes excessive dimming of the image, which improves its naturalness.

For 4K HDR content, calibration also yielded positive results. We eliminated the problem of blue dominance, which translated into a more balanced and natural image. However, managing brightness in HDR materials remains a more complicated issue. The EOTF curve, although it had problems with dimming the image in the range of 10-30% brightness under laboratory conditions, reveals other shortcomings in real scenes. The TV tends to excessively brighten the smallest elements on the screen. As a result, this leads to noticeable halo effects around bright objects. This phenomenon, which we mentioned earlier in the context of contrast and HDR, stems from the technological limitations of the model and is often difficult to eliminate.

In short: although the Filmmaker mode with factory settings looked decent, calibration allowed for an even better effect - minor adjustments resulted in a more balanced image, especially in HDR content. Calibration will be a beneficial step for users seeking the highest quality image.

The function responsible for improving gradation is named "Noise Reduction" in the menu. As we have confirmed, it is worth activating as it has a positive effect on tonal transitions. More importantly, it does not negatively affect film grain or fine details, which sometimes the competition "offers" us.

Image scaling in Samsung Q70D should be rated as average. The manufacturer aims not to artificially sharpen the image but to leave it naturally softened.

With high-quality materials, such as 4K, tonal transitions on the U6NQ look really good – the colours blend nicely and the image is cohesive. Unfortunately, when we switch to content in a lower resolution, 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 clear that the television has trouble rendering subtle tonal transitions.

On the other hand, digital processing performs quite well. The image looks plastic, pleasantly soft, and free of excessive aliasing. 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 does well with image processing.

The Samsung Q70D is the first model in the manufacturer's range to feature a 120Hz panel, resulting in more advanced motion smoothing capabilities compared to lower-category models. Within the menu, three functions are dedicated to improving motion fluidity: "Motion Blur Reduction," "Judder Reduction," and "Clear Motion (LED)." The third option will be discussed separately. The first function enhances sharpness during motion, while the second adjusts the degree of smoothing. The smoothness feature on the Samsung Q70D performs well, with each setting delivering a noticeable effect. This allows viewers to customise the level of fluidity, making it suitable for those who dislike the typical stuttering of films or enjoy watching sports. The accompanying picture illustrates a configuration with mild smoothing, avoiding the soap opera effect.

The panel employed in the Samsung Q70D offers a commendable response time for its class. While it won't deliver razor-sharp motion clarity, it is a strong choice for sports enthusiasts at this price point.

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

As for movies, the TV is equipped with a motion smoothing feature that allows adjusting motion characteristics to personal preferences. This can create a more cinematic effect or increase fluidity in dynamic scenes. Overall, the Hisense U6NQ offers reasonable solutions for motion fluidity that should satisfy both gamers and movie lovers.

The tested television, Samsung Q70D, has four HDMI 2.1 ports, all offering a bandwidth of 40 Gbps. Despite this, no negative effects were noticed during testing. More importantly, the TV supports all features associated with the HDMI 2.1 standard. This will certainly please gamers, as it ensures optimal gaming performance using a console or a PC. While HDR Dolby Vision is absent, the correct implementation of HGIG mode and the absence of any calibration checkerboard issues are noteworthy. Additionally, Samsung stands out by allowing gaming with the smoothness enhancer activated without significant performance degradation. This means that 30 fps titles are perceived similarly to those running at a native 60 frames per second.

Samsung was one of the first manufacturers to introduce the Game Bar, which has been consistently improved. It provides all necessary gameplay information and allows users to adjust "on the fly."

In summary, the Samsung Q70D performs excellently with both consoles and computers. All functions worked seamlessly, and there were no issues. The ability to activate the smoothness enhancer without a noticeable increase in input lag is a game-changing feature.

The 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 for quick changes to picture settings and checking statistics. It also includes a Dolby Vision Gaming mode, which works with low input lag, 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.
