Haier K85F vs PHILIPS PUS9010 (IPS)

Let’s now move on to one of the hottest topics in the world of televisions, which is the quality of HDR performance. In the case of the Haier K85F model, we unfortunately have to make it clear: if you’re looking for equipment to watch content in a wide dynamic range, you should steer clear of this model. The main issue is its very low peak brightness, which during our tests barely reached 250 nits. To give you a better idea of what that means – this level is fine for watching standard SDR content, but it’s absolutely insufficient to show any real benefits of HDR. The image simply doesn’t have the "power" to generate bright, striking highlights. All of our measurements and tests on specialised test patterns confirmed this. As if that wasn’t enough, the television also struggles with colour reproduction. In this budget build, there are no technologies that broaden the colour gamut, such as quantum dot layers (marketed as "QLED"). As a result, the coverage of the DCI-P3 colour space, which is crucial for HDR content, 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 sadly performs worse than in the previously tested 55-inch variant with a VA panel. The difference reaches about 100 nits, which is noticeably significant given the relatively low values. While the VA version could exceed 500 nits, here the maximum brightness reaches around 400 nits. This level still allows for watching movies and series in HDR, especially on streaming platforms, but the effects are clearly more subdued. Bright elements don't have the same impact, and scenes requiring high luminance are less impressive. On the plus side, the coverage of the DCI-P3 colour gamut is commendable. The IPS version offers about 91%, which is roughly 5% more than the variant with a VA panel. This translates into slightly better colour saturation in HDR content, despite the lower brightness. Colours can appear more vivid and cohesive, especially in colourful scenes.

Alright, how does the television handle colours straight out of the box, without any intervention from our side? The Haier K85F offers a whole range of picture modes, such as Dynamic or Eco, but for anyone wanting to watch films according to the creators' intentions, there's essentially only one that matters: Film mode. This is where we focused our tests, and unfortunately, its name has little to do with reality. The picture on factory settings is very far from what we could call cinematic fidelity and requires many adjustments. Let's start with the white balance, which has a clear deficiency of red colour. In practice, this means the entire image has a cool, bluish tint. Even worse is the issue of brightness management, that is, the gamma curves (for SDR) and EOTF (for HDR). Their graph resembles a true rollercoaster, which terribly impacts the viewing experience. This results in unnatural dimming of SDR content, causing details in the shadows to be lost, and in the case of HDR – an excessive brightening that further exacerbates the problem of clipping. Such a combination, which consists of too cool white combined with chaotic brightness and too much blue colour saturation, leads to enormous errors in colour reproduction. Our measurements on a specialist ColourChecker chart showed errors (Delta E) regularly reaching and exceeding values of 8-9. To put it simply: errors above the threshold of 3 are easily noticeable to the naked eye, so such a result means that the colours on the screen are simply heavily distorted.

We evaluated colour reproduction, as always, on factory settings, focusing on the movie mode, which in the case of Philips usually offers the best starting point. This is also a good moment to show how much the same model of TV can vary depending on the panel used. Looking at the white balance, the overall tendency remains similar to the version with the VA panel. There is still excessive red in the whites, however, in the tested unit with the IPS panel, there are also losses in the blue channel. As a result, the picture has a slightly different colour character, which is well illustrated in the comparative materials. This is a very good example showing 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 in SDR content. Colour tests show correct saturation and colour consistency, without glaring errors that could hinder everyday viewing. In HDR materials, it is possible to notice slight losses in reds, but these are not flaws that completely spoil the image perception. The biggest limitations do not stem directly from the colours, but rather from the whites and blacks. The use of an IPS panel and slightly lowered gamma means that the image is slightly boosted in brightness, and weak blacks further affect perceived contrast. This makes everything look brighter, but at the same time, it lacks depth, especially during evening viewing.

No good, but can anything be done about this picture? Is professional calibration able to save the situation? The answer is both yes and no. It needs to be said clearly that there are certain things we cannot overcome. The limitations of the construction itself, namely a poor panel and its narrow colour coverage, mean that you can forget about a sensible HDR effect – we won't be pulling the wool over your eyes on that. The biggest beneficiary of our adjustments is undoubtedly the SDR mode, and it is for watching such content, after calibration, that this television starts to make sense. We managed to tame the white balance in our own way. Although the television only offers basic, 2-point adjustment (rather than precise, 20-point), it's not perfect, but we successfully eliminated that unpleasant, cold "chill" in the picture. Above all, though, we noted a huge 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 an image without artificially dimming or brightening it. The conclusion is simple: even with such a cheap television, professional setting correction can achieve a great deal and extract the maximum potential from it.

After calibration, the picture has been brought to a really reasonable level. The whole thing looks cohesive and natural, and when it comes to colour reproduction, it's hard to definitively say whether we're dealing with a VA or IPS panel. This is a good sign, showing that the television has a solid foundation for further adjustments. The larger colour gamut in this variant is a plus, as it can subtly enhance the depiction of colourful scenes, especially in HDR content. However, this advantage is largely offset by the boosted blacks resulting from the use of an IPS panel. The limited depth of black affects perceived contrast, particularly when watching in a dark room. As a result, despite noticeable improvement post-calibration, the final rating remains the same as that of the variant with a VA panel. Better colours are not able to fully compensate for the weaker blacks.

Let’s move on to digital processing and image scaling, specifically how the Haier K85F handles lower resolution signals, such as from regular television. Right off the bat, we encounter an incredibly annoying and completely incomprehensible issue – the overscan is enabled by default. This means the television artificially enlarges the image, cutting off its edges on every source, even 1080p. To see the full frame, you have to dig into the screen settings each time and manually switch the format to "stretch to 16:9." It's a minor detail, but devilishly frustrating. The scaling of content to 4K resolution can be described in one word: acceptable. And that's about it. The image processor doesn't strip detail from the image, nor does it generate jagged edges or other artifacts. It simply does its job, without any bells and whistles. It’s alright, but nothing more. The most significant and noticeable shortcoming in the digital processing section is, however, the absence of a tone transition smoothing feature. This is an algorithm that could significantly reduce the annoying banding effect we mentioned earlier. Unfortunately, the manufacturer did not foresee such a solution, condemning us to watch the imperfections of the panel and low-quality material in all their glory.

In the Philips PUS9010, we find another iteration of the P5 Perfect Picture image processor, which aims to improve the quality of lower-grade materials. One of the components of this system is a distortion reduction function that smooths tonal transitions. It works effectively and actually reduces visible banding. Unfortunately, it does so quite aggressively. In practice, it can mute details such as material textures or film grain. This is a clear compromise, so we wouldn't particularly recommend it for movie sessions. For more casual content, like YouTube or regular television, it performs much better. The P5 processor also handles lower resolution materials quite well. The image is soft, at times even too soft, but it can easily be corrected using the sharpness slider, adjusting the effect to personal preferences. A positive aspect is also the absence of edge cropping in SD materials, which is still not standard in this class of televisions.

The panel in the K85F model operates at a native refresh rate of 60 Hz, which sets certain expectations for image smoothness right from the start. However, we must admit that we were very positively surprised when we found two separate motion control sliders in the settings menu: one labelled "Motion Blur Reduction" and the other "De-Judder." Such generosity in this price segment is an absolute rarity, as manufacturers usually offer at most one shared option. Unfortunately, our enthusiasm faded as quickly as it appeared. It soon became clear why Haier was so "generous" – the slider responsible for reducing motion blur is simply a decoy. Sliding it makes absolutely no visible difference 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 mainly by sports fans and gamers. This is especially noticeable in dynamic scenes where the motion is sharp, and annoying blur is almost non-existent. When it comes to movies (standard 24 fps), Philips offers us a proven set of settings known from its higher series. Two sliders are used to control motion. “Smoothness” allows you to adjust the picture to your liking: at low settings, it maintains a cinematic character, while moving the slider to the right gives us a perfectly smooth, albeit slightly “theatrical” effect. Meanwhile, “Motion Blur Reduction” is a feature designed for sports – it ensures that fast-moving objects do not lose detail and remain clear.

Let’s move on to the features for gamers, although we must point out straight away that this is more of a proposal for the "occasional" ones. The manufacturer does boast in the specifications about having HDMI 2.1 ports, which looks impressive on paper, but in reality, it’s largely a marketing ploy. What good is a modern port when 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 takes away HDMI 2.1’s key advantage. What a shame. (That’s why in our tests we note this as HDMI 2.0 ports). Another odd issue is the TV's response to an attempt to calibrate HDR from the console. Changes to brightness settings result in very unnatural image behaviour, which could suggest incorrect implementation of the HGiG standard. To be honest, one shouldn’t worry too much about this, as we have repeatedly mentioned, we simply do not recommend using any HDR content on this screen. However, to counterbalance the negatives, the Haier K85F does have two big and unexpected advantages. The first is the presence of ALLM, or automatic game mode, which switches the TV 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 operates within a very modest range of 48-60 Hz, its mere presence is commendable. Thanks to this, the image in games can “tear” less, which realistically improves the gaming experience.

Philips PUS9010 is a solid machine for gaming. It has everything that’s important: VRR, automatic game mode (ALLM), and support for HGiG. The latter is fantastic – it allows you to set HDR in games exactly the way the developers envisioned. The TV handles 120 Hz refresh rates effortlessly at every popular resolution (1080p, 1440p, and 4K). It doesn’t matter if you connect a PS5, Xbox, or a powerful PC – everything runs smoothly and just as it should. Gamers will also appreciate the Game Bar. It’s a quick, clear menu where you can immediately see if the low latency mode is active. This is especially useful when frequently switching between different consoles. The whole experience is enhanced by Ambilight. Evening sessions with this backlighting create a whole different level of atmosphere; the image seems larger, and dynamic scenes are even more impressive. Even if someone isn’t a fan of such “gimmicks,” it’s hard to deny that it makes an impression.
