Philips PUS8359 (VA) vs Hisense U6NQ

The Philips PUS8359 has low brightness levels; however, dynamic tone mapping works surprisingly well, making it worth praising!

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 colors, 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 for fidelity to the source material was the "Film" mode, which we used during our tests. As with all factory modes in televisions, it has flaws, and we’ll now examine what went wrong in both SDR and HDR materials. In both cases, the white balance showed an excessive dominance of green and red, resulting in a yellowish tint across the entire image. This caused issues such as yellowed whites and problems with skin tones. This was clearly illustrated on the "ColourChecker" palette, where each tested sample shifted towards warmer equivalents. The foundation of the image lies in contrast and black levels, represented by gamma charts and the EOTF curve. Looking at the gamma chart, we saw a real rollercoaster, with both elevated and lowered gamma. The elevated gamma caused visibility issues in blacks, while the lowered gamma led to a dramatic drop in contrast. In this context, the EOTF curve performed significantly better, as it only mildly brightened the image.

The Hisense U6NQ in Filmmaker mode offers truly decent color 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 color 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 characteristic – 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.

Philips offers a wide range of image calibration tools in its higher-end and more affordable models. We used these tools, but the process was not as straightforward as many might expect. While we adjusted the white balance, significantly improved the gamma, and refined the EOTF curve in both SDR and HDR content, the deltaE errors remained extremely high. Several factors contribute to this situation, including the limited coverage of the DCI-P3 colour gamut and the unit's maximum brightness in HDR materials.

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 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. For users seeking the highest quality image, calibration will be a beneficial step.

In this paragraph, we will take a look at two functionalities. We will once again look at the function responsible for tonal transitions, but we will also check how the television handles image scaling. The option responsible for smooth gradation is called "Distortion Reduction." As we have established, it quite effectively smooths out imperfections. However, we need to point out two things: we cannot enable it for HDR material and it blurs details in films.

The tested television cannot boast the best image scaling. There is a noticeable overall blurriness of the image, but what is worse, it blurs details. This is particularly visible on the branches and the model's hair. Additionally, a characteristic white halo can often be seen surrounding characters.

With high-quality materials, such as 4K, tonal transitions on the U6NQ look really good – the colors 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, is 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 Philips PUS8359 is not the best choice for watching sports. This is primarily due to the absence of even a basic motion smoothing feature, which given the price point, is not entirely surprising. Additionally, the television uses a VA panel, which, while offering high contrast, is not known for its sharpness or fast response times. As demonstrated in our analysis, fast-moving scenes often result in noticeable blurring, a common issue with this type of panel.

Although it is not an ideal option, the TV can be used for sports viewing with some compromises, particularly regarding motion sharpness. It's also worth noting that films are prone to stuttering since the TV lacks any form of motion smoothing, even the most basic functionality.

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.

Unsurprisingly the Philips PUS8359/12 offers only the most basic support for consoles. When connecting a console, users can rely on features like VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). VRR is particularly commendable, as even some higher-end models can struggle with this functionality.

A noteworthy addition is the implementation of a dedicated GameBar, which allows for on-the-fly adjustments without needing to exit the game, minimising unnecessary distractions. This feature also provides options to tailor gameplay for individuals with disabilities, making it a highly commendable inclusion.

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.
