Hisense U6NQ vs Samsung Q6F (IPS)

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.

Unfortunately, the Samsung Q6F is a very dark model. Its peak brightness in HDR does not exceed 250 nits, which is definitely too low to even speak of any "high dynamic range" effect, or HDR. In practice, it's better to stick to content in SDR format, which simply looks more predictable on this TV. Another problem is the global dimming technique – in scenes with a lot of black, the TV drastically dims the entire panel to artificially improve the black levels. This causes the image to become even darker, and brightness can drop below 100 nits. The only consolation is the QLED technology, but even here it's average. The applied quantum dot layer is not top-notch, as the coverage of the DCI-P3 color gamut does not exceed 90%. As a result, colors in HDR content may just seem under-saturated.

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.

We tested the television in Filmmaker mode, which showed us two completely different faces of this model. Looking at SDR content, we were honestly shocked at how good this TV looks straight out of the box. It was really hard to nitpick anything here. Despite a slight “haze” in the white balance or somewhat brightened details in the blacks (which directly results from the IPS panel's design), color errors hovered around the “2” level. This is surprisingly good, even outstanding, considering the price of this device.

On the other hand, what the Q6F displayed in terms of colors after switching to HDR mode was a very unpleasant surprise. The errors in color reproduction and palette were so huge that our charts literally ran out of scale. Of course, since Samsung even in such an inexpensive model offers very advanced calibration possibilities, we decided to approach the subject professionally and check what could be done about it during calibration.

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.

After our calibration, the colors in SDR mode looked even better – the result is quite surprising, as color errors at level "1" are something usually seen in devices costing several thousand dollars. In this regard, the Q6F is really a great screen for everyday television, less demanding series, or movies. Unfortunately, our interference in HDR mode did not bring about a noticeable improvement. The television, due to its poor black levels and low coverage of a wide color gamut, still has significant problems with proper color saturation, especially red. This is an example of a device where HDR mainly exists as a label on the box – for everyday use, we definitely recommend watching content in SDR format.

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 Q6F handles upscaling lower resolution content to native 4K very well. The scaling is surprisingly good here, even for such a budget TV from the QLED series. The only downside is when we watch very low-resolution material, like 576p (typical for old DVD players) – then the image may be slightly cropped. This is because the TV does not allow for the Overscan feature to be turned off, which is a common issue with Samsung devices.

The situation is completely different when it comes to digital processing, which is the attempt to smooth the image from unwanted artifacts. Here, the TV completely fails. Although we find a function in the menu called "Noise Reduction", it yields no visible results regardless of the slider setting. The only thing it seems to do is introduce unwanted errors into the image. Despite its presence in the system, we definitely do not recommend using it.

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 60 Hz panel in the Samsung Q6F is the standard in this price range, which makes it a rather average model for dynamic sports or gaming. However, in the case of movies, the TV performs quite well thanks to the smoothing feature. The "Motion Smoothing" option allows you to adjust the fluidity of motion to your own preferences – from maintaining a cinematic feel to full fluidity.

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.

We won’t beat around the bush – the Q6F is not a television designed with gamers in mind. While it does have features like ALLM (Auto Low Latency Mode) and VRR frame synchronization for consoles, the list of benefits pretty much ends there. Besides these basics, the TV offers nothing more that might satisfy those who spend a lot of time in front of a console. It’s a real shame that such a useful tool as Game Bar is missing here, which in Samsung’s higher models allows for quick control of game parameters. In terms of gaming, this is an absolutely basic model and is only suitable for "casual" gamers.
