Philips PUS8079 vs Samsung Neo QLED QN70F / QN74F / QN77F

The maximum brightness in content with a wide tonal range at 202 nits is extremely low and practically prevents watching movies and series on streaming platforms in the highest quality. It's worth mentioning that in this case, using the HDR format equipped with dynamic metadata won't help either. Why won't it help? Because the only such format implemented in the television is HDR10+, which is extremely unpopular, and films recorded in this format are scarce. It’s also worth noting that PUS8079 uses WLED backlighting, which unfortunately is not the best solution, resulting in coverage of only 80% of the wide DCI-P3 colour gamut. The effect of this reality is significantly less intense colours in HDR content.

QN70F is a television that can positively surprise when it comes to brightness. In ideal testing conditions, it reaches even 800 nits, which – for this price range – is a really solid value. Of course, that’s a result from test patterns, so we decided to check how it performs in practice, on real films. Here, the television somewhat tempers its capabilities. In most of the tested scenes – e.g. in "The Meg" – the actual HDR brightness remained around 500 nits. That’s still a decent result, allowing you to enjoy HDR effects, although it’s far from perfection. On the other hand, we have a QLED screen with a quantum dot layer, which means very good colour reproduction capabilities. Colours are vivid and saturated. QN70F covers about 94% of the DCI-P3 colour space, and in the wider BT.2020 palette, it exceeds 75%, so in this respect, there’s nothing to be ashamed of.

The best factory mode in terms of colour reproduction and fidelity to the director's vision was "Film". While it was the best of the predefined modes, it still had significant discrepancies between what the filmmaker wanted to convey and what the tested television displayed. In both SDR and HDR materials (though to a lesser extent in the latter), the white balance, which is the most fundamental element responsible for image purity, turned out to be somewhat of a repeat of the vibrant mode, with a blue tint reminiscent of what you see in retail displays. Moving directly to the SDR materials and what affects contrast, namely gamma, we see it being severely reduced. This leads to cutting off already minimal contrast resources and brightening the entire image. In the EOTF curve, responsible for the increase in brightness pace in HDR materials, we instead see a strong drop below the reference line, which, given the limited light output of the television, significantly impacted the perception of those contents, which were even more dimmed. We won’t separate the quality assessments of the colours themselves since, in both cases, they achieved astronomical deltaE values, being simply completely different from what they should be.

We tested the QN70F in the best default picture mode, which is Filmmaker Mode. And it must be admitted that in this particular test unit, the factory settings performed quite well. The picture was calm, natural, and despite slight deviations – pleasant to watch. The biggest error was a slight dominance of red in the white balance, which caused a slight pinkish tint over the entire scene. However, it wasn't a glaring flaw – rather subtle and only noticeable when directly compared to a properly calibrated screen. A slightly bigger issue arose in the brightness characteristics. The TV tends to lower the brightness of parts of the image that should be displayed brighter. As a result, some details can appear slightly dimmed – they don't completely disappear, but they don't stand out as clearly as they should. Nonetheless, as for a TV in this range and in these settings – we consider the result a good starting point for further calibration.

Luckily, Philips implements advanced image correction tools in all of its TVs. SDR content has benefited the most here, and the huge deltaE errors have been significantly corrected, with both white balance and gamma being substantially reworked. While we can't say it's reference-quality image, it's definitely better, and you can watch a movie or series without causing a headache, especially for your eyes. Naturally, HDR materials, due to the very low luminance of the TV, could not be corrected to the same high degree as those with a standard colour palette, but we managed to roughly straighten out the EOTF curve and the white balance. Unfortunately, that was all we could squeeze out of our unit, although it's worth noting that each unit is different and has entirely different errors, whether minor or major.

After calibration, the QN70F shows that it can offer a really high level of colour reproduction. It has managed to nearly perfectly balance the white point, and the values in the Color Checker test dropped below level 3 – that is, below the threshold at which the average eye can notice differences. The image looks natural, and the colours are faithfully reproduced, without excessive saturation or the coolness known from factory settings. It must be acknowledged that Samsung provides very extensive calibration options – not only for enthusiasts but also for professionals. The QN70F takes advantage of this potential and, after appropriate settings, can come close to significantly more expensive models in terms of colour accuracy. The only thing that could still be picked on is the brightness characteristic. There is still a tendency to brighten the smallest sections of the image – particularly those that should remain darker. However, this is a design feature of this model, not a calibration error. Despite this, the final result definitely deserves recognition.

We will return once again to the issue of tonal transitions, but in the context of overall image quality improvement. As we can observe in the photo on the left, the gradation enhancement feature works brilliantly. Furthermore, it offers several settings, and each of them, even the lowest, provides a beneficial effect, and, what’s more, does not soften the film grain effect. We will repeat once again that this feature is the biggest advantage of the tested television.

Secondly, we will look at image scaling. Here, the tested television performed worse. We can notice, above all, the strongly jagged fine details and the characteristic white glow around figures. We must not forget about the significant artificial sharpening of the image.

Samsung QN70F offers a distortion reduction feature that improves the smoothness of tonal transitions. In "Standard" mode, it works quite well – smoothing out problematic transitions without significantly interfering with the structure of the image. Film grain is partially removed, but details like texture and skin structure remain visible. "High" mode operates much more aggressively. The smoothing is stronger, but at the cost of a noticeable loss of detail. Therefore, in practice, we recommend sticking with the "Standard" setting or turning off this feature altogether. The improvement in gradation may be less spectacular, but the image retains more naturalness.

When it comes to upscaling low-quality content, the QN70F performs very well. Tests with lower resolution images went really well. Despite some slight aliasing of contours, everything looks clean and clear, even if the original content was very poor quality. It's just a pity that the television has an overscan issue that cannot be completely turned off. As a result, images with very low resolution may be slightly cropped, which is mainly noticeable on subtitles or the interface.

This paragraph, unlike the others, will be extremely short. The reason for this situation is the lack of implementation of even the most basic motion smoothing function, which was to be expected given the price of the device. We also note that we are dealing with a VA panel, whose sharpness will not be the best under the sun. This type of panel is mainly associated with high contrast, which goes hand in hand with a relatively slow response time, as we can clearly read from the panel analysis results. As you can see, from the images captured in quick motion, the picture is blurred, typical for this type of panel. Although it may not be the ideal option, it can conditionally be used for watching sports, although one must keep in mind the less than optimal sharpness in motion. It's worth mentioning that movies will exhibit stuttering, as the television does not have any, not even the simplest, motion smoother.

The QN70F is a television with a refresh rate of 144 Hz, which in itself places it among the best when it comes to image smoothness. Whether we're watching fast-paced sports broadcasts or gaming on a console – the picture looks fantastic. There's no sense of stuttering, clipping, or the typical "judder" seen in lower-end models during fast motion. Samsung also allows you to adjust the smoothness to your own preferences. In the picture clarity settings, we find options such as motion blur reduction and judder reduction – each of which can be adjusted independently. This is especially useful when we are watching content with a lower frame rate and want to give it a smoother, more cinematic feel – or conversely, maintain the natural filmic "feel" of 24 frames.

Philips PUS8079 offers only the most basic support for gaming in the form of ALLM, VRR, and Game Bar. The most important information is that thanks to the implementation of the feature responsible for dynamic refresh rate adjustment, the image is actually quite smooth for this price range and does not 'tear' the image.

A slightly greater nod towards gamers is the introduction of the Game Bar, allowing for settings adjustments 'on the fly'. This means we won’t have to exit the game to make any changes to the image. Importantly, it hasn’t been stripped of options known from higher models. We can find features such as shadow enhancement for better visibility in shadows and a colour filter for players with visual impairments.

Samsung QN70F is a really solid choice for gamers. It features four HDMI 2.1 ports with full bandwidth of 48 Gbps, which means full support for gaming in 4K at 144 Hz refresh rate. Plus, it has all the basic features we expect today: automatic game mode (ALLM), variable refresh rate (VRR), and a very well-designed, intuitive Game Bar that displays information about the mode, resolution, and frame rate.

The Game Motion Plus feature is also worth noting, as it allows for the addition of artificial frames to games running at 60 fps or less. It works surprisingly well and improves gameplay smoothness in many titles—especially in those where consoles struggle to maintain a stable frame rate—without significant latency.

Unfortunately, there are some drawbacks. The lack of support for Dolby Vision mode is not surprising—it’s a standard for Samsung. However, the absence of the HGiG feature is far more disappointing. Worse still, it was removed in a software update, which might catch users who previously relied on it off guard. Without HGiG, one cannot manually set the maximum HDR brightness from the console, resulting in some games looking slightly overexposed—especially if the TV misinterprets the tonal range. Why Samsung, a brand that has set the standards for gaming features for years, decided to take such a step is hard to say. At the time of writing this review, the tested TV was running on software version 1110—and frankly, if you care about full support for gamers, it’s better to hold off on updates for now.
