Philips PUS8359 (IPS) vs Hisense U7Q

The quality of the HDR effect on the Philips PUS8359/12 TV is also not impressive. The brightness level of 280 nits is too low, resembling standard SDR more than true HDR, which is clearly visible on the five tested test patterns. Additionally, the television does not excel in terms of colour gamut coverage – a mere 76% of DCI-P3 is a result that can be considered poor, especially compared to other models in a similar price range.

Since the algorithms responsible for blacks are performing quite well, we expected a similarly good effect regarding brightness and overall HDR quality. Unfortunately – here we have to disappoint you a bit.

The U7Q is a sufficiently bright television – under the best conditions, it can achieve around 800 nits, which indeed impresses on some scenes, especially in scenes like those from the film The Meg. Bright areas can shine, and the HDR effect is noticeable. The problem arises when there are very small, bright elements on a dark background – for example, in Sicario 2 or in the second scene from the film Life of Pi. In such moments, the dimming algorithms work too aggressively. Yes, the blacks look great then, but the brightest points can almost completely disappear, causing the HDR effect to vanish and the details to be barely visible. It's just the nature of this technology in this price segment.

As a consolation, it's worth mentioning that the U7Q is marketed as QLED (in practice, a PFS layer is used, which works very similarly), and it is indeed capable of displaying a wide colour palette – a DCI-P3 coverage of around 94% is a very good result for this class.

The most faithful factory mode in terms of compliance with the source material turned out to be "Film", which was used in our tests. Nevertheless, like other factory modes, it also had its flaws. In both SDR and HDR materials, we noticed issues with white balance, where the dominance of green and red resulted in a yellowish tint. This effect was particularly noticeable in the form of yellowed whites and unnatural skin tones. The "ColourChecker" palette test showed that every colour had shifted to warmer tones, affecting colour reproduction accuracy. A key aspect of the image is also contrast and brightness, which can be assessed by analysing gamma charts and the EOTF curve. On the gamma chart, we noticed significant deviations – both excessively high values, which caused loss of detail in the shadows, and excessively low values, which led to a drastic drop in contrast. Compared to gamma, the EOTF curve performed better, only slightly brightening the image, which had a less negative impact on overall quality.

We tested the U7Q in the best possible picture mode, which is Filmmaker Mode. This is the mode that is supposed to provide the most "filmic" and creator-intended experience – right out of the box. Unfortunately… even this professionally sounding name does not guarantee a perfect picture.

In our unit, the problem lay in the incorrectly set white balance. Both in HD and 4K content, the picture had too much blue and red, which caused the screen to take on a slightly rosy tint. It didn't look terrible, but it was noticeable – especially in bright scenes and white backgrounds. This alone could perhaps be forgiven, but the biggest problem is managing brightness in HDR content. The EOTF curve from measurements confirms what we saw earlier during scene tests: the television can overly darken the smallest bright elements, causing them to nearly disappear, or on the contrary – excessively brighten the brightest ones, which affects the naturalness of the picture.

Philips, both in its cheaper and more expensive models, offers a wide range of tools for image calibration. We used them to improve the quality of the displayed image, although it was not as straightforward as it might seem. We managed to adjust the white balance, improve the gamma, and fine-tune the EOTF curve, but despite these efforts, the deltaE errors were still at a very high level. The main causes were limited coverage of the DCI-P3 palette and low maximum brightness, which significantly affected the final result. Although the overall presentation is much better, the design features of the television did not allow us to achieve spectacular results.

Thanks to specialised tools, we managed to correct the colour quality in SDR content to nearly perfection. In materials with lower dynamic range, the delta E errors dropped below 0.5, which can be regarded as an almost reference result. The picture on television, YouTube, or classic Full HD looks really very good after calibration. Alright – but where did we not manage to improve the image so easily? Primarily, it concerns HDR quality content. Although we managed to somewhat 'tame' the white balance and eliminate pink tints in most scenes, unfortunately, we no longer had full control over brightness management. We set the local dimming settings according to the best observations – SDR: Medium, HDR: High – but the U7Q still did everything a bit its own way. There were still cases of excessive dimming or brightening of details that calibration simply could not eliminate. And although the overall reception of the content is significantly better, one must reckon that the U7Q will always have something to say at the end with an 'but'.

In this paragraph, we will take a look at two functionalities. Once again, we will examine the feature 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 irregularities. However, we must point out two things: we are unable to enable it for HDR materials, and that it blurs details in films.

The tested television cannot boast the best image scaling. The overall blurriness of the image is quite noticeable, but worse still, it blurs details. This is particularly evident on the branches and the model's hair. A characteristic white halo around the figures is also visible.

There are situations where we would like to smooth out tonal transitions a bit, especially in older materials – those with limited source quality. The U7Q is equipped with a feature called "Smooth and Gradient Image," but unfortunately... it works very poorly. In the "Low" option, the effects are practically unnoticeable, and other settings smooth details but do not improve tonal transitions. The only positive aspect is that the feature does not interfere with film grain, so it does not ruin the natural structure of the image.

Fortunately, upscaling content performs quite well. The image is not excessively sharpened, and there is no artificial clarity – and although it is known that this is not the level of high-end televisions, the U7Q handles displaying really old content in a completely acceptable manner without any issues.

Philips PUS8359 is not the best choice for watching sport. The lack of even basic motion smoothing functionality means that the image during fast-moving scenes is not adequately clear. Despite the use of an IPS panel (43 and 55'), which theoretically should offer better sharpness than VA panel variants, there is no noticeable improvement regarding blurring. In pictures with fast movement, the figure of the alien is clearly blurry, indicating that the television struggles to maintain sharpness in dynamic shots.

U7Q is indeed a very fast television, just like its more powerful version "PRO". At a resolution of 4K, it supports up to 144 Hz refresh rate, and if someone wants even more – in Full HD, you can achieve up to 240 Hz! This will mainly benefit PC gamers, but it is worth appreciating – it is a rarely seen feature in this price segment. Right from the start, it is clear that the U7Q has been designed with dynamic content in mind, such as games or sport. In films, we are not left "out in the cold" either – the U7Q offers an "Ultra Motion Smoothness" feature, where using two sliders you can adjust whether you prefer a smoother, theatrical image or something closer to a cinematic style with a visible film frame. It is good that, as with most manufacturers, we have a choice here as well and can adjust it to our own preferences.

In terms of compatibility with consoles, Philips PUS8359 is mainly suited for occasional gamers. Although the television is equipped with an HDMI 2.0 port, it offers features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and Game Bar. ALLM automatically switches the television to low latency mode, making quicker reactions easier during gameplay, while VRR smoothly adjusts the refresh rate, eliminating screen tearing issues. The Game Bar provides quick access to game settings and real-time monitoring of parameters; however, in our opinion, it performs worse compared to the competition's solutions.

However, more demanding gamers may feel unsatisfied. Philips PUS8359 does not support advanced HDR formats in games or higher refresh rates, which is due to the use of a 60 Hz panel. These shortcomings limit the television's capabilities in delivering smooth and detailed experiences during fast, dynamic gameplay.

The Hisense U7Q is a television designed with gamers in mind – and this is immediately evident from its gaming capabilities. It has practically everything you could wish for: variable refresh rate (VRR) – check, automatic game mode (ALLM) – check, and on top of that, high refresh rates of up to 240 Hz in Full HD and support for various resolutions, not just 4K. This is truly a great set of features that makes the U7Q perform well both in fast-paced first-person shooters on consoles and in more demanding titles on PC. Of course – as with most Hisense models – there is a lack of proper implementation of the HGiG feature. It's a shame because HGiG allows console brightness to be matched to a specific television, which in practice makes displaying HDR games according to the creators' intent much easier. Without this, you simply have to reckon with certain limitations in the final HDR image in games.
