Haier K85F vs PHILIPS PUS9010 (IPS)

Let’s now turn to one of the hottest topics in the world of televisions, namely the quality of HDR effect. In the case of the Haier K85F model, we must unfortunately make it clear: if you are looking for equipment to watch content in a wide dynamic range, you should avoid this model at all costs. The main problem is its very low peak brightness, which during our tests barely reached 250 nits. To give you a better idea of what that means – such a value is fine for watching standard SDR content, but it is absolutely insufficient to showcase any real benefits of HDR. The image simply lacks the "power" to generate bright, striking highlights. All our measurements and tests on specialist patterns only confirmed this. As if that weren't enough, the television also struggles with colour reproduction. In this budget build, we won't find any technologies to expand the colour palette, such as quantum dot layers (marketed as "QLED"). As a result, the coverage of the DCI-P3 colour space, which is crucial for HDR materials, is only around 80%. In practice, this means that the image will not only be dark but also devoid of the vibrant, saturated colours that the director wanted to show us.

In the Philips PUS9010 version with an IPS panel, the HDR brightness unfortunately performs worse than in the previously tested 55-inch model with a VA panel. The difference reaches about 100 nits, which is quite noticeable given the relatively low values. While the VA version could exceed 500 nits, here the maximum brightness is around 400 nits. This level still allows for watching movies and series in HDR, especially on streaming platforms, but the effects are clearly muted. Bright elements do not have the same impact, and scenes requiring high luminance appear less impressive. On the positive side, the coverage of the DCI-P3 colour gamut is commendable. The IPS version offers around 91%, which is about 5% more than the variant with a VA panel. This translates to somewhat better colour saturation in HDR content, despite the lower brightness. Colours can appear more vibrant and cohesive, especially in colourful scenes.

Well, how does the television perform with colours straight out of the box, without any interference from our side? The Haier K85F offers a full range of picture modes, such as Dynamic and Eco, but for anyone who wants to watch films according to the creators' intentions, only one really matters: Film mode. That is where we focused our tests, and unfortunately, its name has little to do with reality. The picture in the factory settings is very far from what we could call cinematic fidelity and requires numerous adjustments. Let's start with the white balance, which has a noticeable deficiency of red. In practice, this means that the entire image has a cool, bluish tint. The situation is even worse regarding brightness management, namely the gamma curve (for SDR) and EOTF (for HDR). Their graph resembles a real rollercoaster, which has a disastrous impact on the viewing experience. This results in unnatural dimming of SDR content, causing details in shadows to be lost, and in the case of HDR – excessive brightness, which further exacerbates the issue of clipping. Such a combination, namely too cool white combined with chaotic brightness and excessive blue saturation, results in significant errors in colour reproduction. Our measurements on the specialist ColorChecker chart revealed errors (Delta E) regularly reaching and exceeding values of 8-9. Put simply, errors above the threshold of 3 are already easily noticeable to the naked eye, so such a result means that the colours on the screen are simply heavily distorted.

We assessed the colour reproduction, as always, on the factory settings, focusing on the movie mode, which for Philips usually provides the best starting point. This is also a good moment to demonstrate how much the same TV model can vary depending on the type of panel used. Looking at the white balance, the overall tendency remains similar to the variant with the VA panel. Excessive red in the whites is still noticeable, but in the tested unit with an IPS panel, there are also deficits in the blue channel. As a result, the image has a slightly different colour character, which can be clearly seen in the comparative materials. This is a very good example illustrating why ready-made settings downloaded from the internet do not always work even within the same model.

However, returning to the assessment itself, this unit performs quite well, especially with SDR content. Colour tests show correct saturation and consistency, with no glaring errors that could interfere with everyday viewing. In HDR materials, slight deficits in reds can already be noticed, but these are not flaws that spoil the overall perception of the image. The biggest limitations do not come directly from the colours, but rather from the white and black levels. The use of an IPS panel and slightly lowered gamma results in the image being slightly boosted in brightness, and the poor black levels further affect the perceived contrast. This makes the overall picture look brighter, but at the same time it loses depth, especially during evening viewing.

Well, is there anything that can be done about this picture? Can professional calibration save the situation? The answer is both yes and no. It must be clearly stated that there are certain limitations we cannot overcome. The constraints of the design itself, meaning simply a poor panel and its narrow colour coverage, make it impossible to expect a reasonable HDR effect – we won't mislead you on that. The biggest beneficiary of our adjustments is undoubtedly the SDR mode, and it is indeed for watching such content, after calibration, that this television starts to make sense. We managed to somewhat tame the white balance. Although the television only offers basic 2-point adjustment (rather than precise 20-point), so it's not perfect, we successfully eliminated that unpleasant, cold "chill" in the picture. Above all, however, we noted a significant improvement in brightness management. The gamma curve, which previously resembled a rollercoaster, looks like an almost perfectly straight line after calibration. This is a sign that the television can finally display images without artificially dimming or brightening them. The conclusion is simple: even with such a cheap television, professional adjustment of the settings can achieve a lot and extract the maximum potential from it.

After calibration, the picture was brought to a truly sensible level. The overall look is coherent and natural, and when it comes to colour reproduction, it is difficult to unequivocally state whether we are dealing with a VA or IPS panel. This is a good sign, showing that the television has a solid foundation for further adjustments. It is worth noting the larger colour gamut coverage in this variant, which can subtly enhance the perception of colourful scenes, particularly in HDR content. However, this advantage is largely balanced out by the boosted black levels resulting from the use of an IPS panel. The limited black depth affects the perceived contrast, especially when watching in a dark room. Consequently, despite the noticeable improvement after calibration, the final assessment remains the same as in the variant with the VA panel. Better colours are unable to fully compensate for the weaker black levels.

Let's move on to digital processing and image scaling, specifically how the Haier K85F handles lower resolution signals, such as those from standard television. Right from the start, we encounter an extremely annoying and completely incomprehensible issue – overscan that is enabled by default. This means that the television artificially enlarges the image, cropping its edges, and this happens on every source, even 1080p. To see the full frame, you have to dig through the screen settings each time and manually switch the format to "expand to 16:9". It's a detail, but it's devilishly frustrating. The very act of scaling content to 4K resolution can be summed up in one word: acceptable. And that's about it. The image processor does not strip details from the picture, nor does it generate jagged edges or other artifacts. It simply does its job, without any fireworks. It's alright, but nothing more. However, the biggest and most noticeable shortcoming in the digital processing section is the absence of a smooth tonal transition feature. This is an algorithm that could significantly reduce the annoying banding effect we mentioned earlier. Unfortunately, the manufacturer did not provide such a solution, condemning us to watch the imperfections of the panel and low-quality materials in full view.

In the Philips PUS9010, we find another iteration of the P5 Perfect Picture image processor, designed to improve the quality of inferior materials. One of the components of this system is the distortion reduction function, which is responsible for smoothing tonal transitions. It works effectively and indeed reduces the visible colour gradation. Unfortunately, it does so quite aggressively. In practice, it can dim details such as the texture of materials or film grain. This is a notable compromise, so we would not recommend it for movie screenings. However, it performs significantly better with more casual content like YouTube or regular television. The P5 processor also manages quite well with lower resolution materials. The image is soft, at times even too soft, but this can easily be corrected with the sharpness slider, adjusting the effect to personal preference. A positive aspect is also the lack of edge trimming in SD materials, which is still not standard in this class of televisions.

The matrix in the K85F model operates at a native refresh rate of 60 Hz, which right from the start sets certain expectations regarding image fluidity. However, we must admit that we were very positively surprised when we found two separate sliders for motion control in the settings menu: one labelled as "Motion Blur Reduction" and the other "De-Judder". Such generosity in this price segment is an absolute rarity, as typically manufacturers offer at most one shared option. Unfortunately, our enthusiasm waned as quickly as it appeared. It soon became clear why Haier was so "generous" – the slider responsible for motion blur reduction is simply a dummy. Its adjustment brings absolutely no visible effect on the screen, so only one of the two options works.

Philips PUS9010 has a 4K panel with a refresh rate of 144 Hz, which will be appreciated primarily by sports fans and gamers. This is especially evident in dynamic scenes where the motion is sharp, and annoying blur is almost non-existent. When it comes to movies (standard 24 fps), Philips gives us a proven set of settings known from higher series. Two sliders are used to control motion. “Smoothness” allows you to adjust the image to your own taste: at low settings, we maintain a cinematic character, while moving the slider to the right gives us a perfectly smooth, albeit somewhat “theatrical” effect. On the other hand, “Motion Blur Reduction” is a function designed for sports – it ensures that fast-moving objects do not lose detail and remain clear.

Let's move on to features for gamers, although we must emphasise at the outset that this is more of a proposal for the "casual" ones. The manufacturer boasts in the specifications about the presence of HDMI 2.1 ports, which looks impressive on paper, but in reality, it is largely a marketing ploy. What good is a modern port if the heart of the television is a panel with a refresh rate of 60 Hz? It physically cannot display a signal at 120 frames per second, even at lower resolutions, which deprives the HDMI 2.1 port of its most significant advantage. It's a shame. (That’s why we mark it as HDMI 2.0 in our tests). Another curious peculiarity is the television's reaction to attempts to calibrate HDR from the console level. Changes to brightness settings cause very unnatural image behaviour, which might suggest an incorrect implementation of the HGiG standard. To be honest, however, one shouldn't worry too much about this, because as we've mentioned numerous times, we simply do not recommend using any HDR content on this screen. However, to avoid being too negative, the Haier K85F also has two significant and unexpected advantages. The first is the presence of ALLM, or Auto Low Latency Mode, which switches the television to low latency mode as soon as it detects a connected console. The second, even bigger surprise, is support for VRR, or Variable Refresh Rate. While it works within a very modest range of 48-60 Hz, its mere presence is commendable. As a result, the image in games can experience less "tearing," which significantly improves the gaming experience.

The Philips PUS9010 is a truly solid machine for gaming. It has everything that matters: VRR, automatic game mode (ALLM), and support for HGiG. The latter is a great feature – it allows HDR in games to be set exactly as the developers envisioned. The television handles 120 Hz refresh rates effortlessly at every popular resolution (1080p, 1440p, and 4K). Whether you connect a PS5, Xbox, or a powerful PC, everything functions stably and simply as it should. Gamers will also appreciate the Game Bar. This quick, clear menu immediately shows whether the low latency mode is active. This is especially useful when frequently switching between different consoles. The whole experience is complemented by Ambilight. Evening sessions with this backlighting take the atmosphere to a whole new level – the image seems larger, and dynamic scenes leave an even better impression. Even if someone isn’t a fan of such “gadgets”, it’s hard to deny that it’s impressive.
