Philips PUS8500 vs Haier K85F

When it comes to HDR performance on the PUS8560, it's safe to say that it's rather average. The brightness of the panel is around 350 nits, so we consider this to be the absolute minimum for watching content in this format. However, it’s not a result that will impress viewers looking for the best possible picture.

On the plus side, it's worth noting that the PUS8500 series – including the PUS8560/12 tested here – is marketed as a QLED television. And indeed, we can expect a wider colour gamut here. This model is equipped with an additional filter (PFS), and the DCI-P3 coverage of around 90% should suffice for most users. This filter operates very similarly to quantum dots. As a result, colours are quite well-saturated. It's not an outstanding result, but it's entirely sufficient for watching movies and series from streaming platforms.

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.

We tested the television on the best available factory settings, that is, in Film/Filmmaker mode – this is the mode we recommend for everyday viewing. Unfortunately, it is not without its flaws. Both in HD and HDR content, the image had a distinct tendency to pinkness, caused by an excess of red and blue in the white balance. Another issue turned out to be excessive brightness of the image, as confirmed by both the gamma graph and the EOTF curve. This characteristic was responsible for the loss of detail and washed-out colours in more challenging HDR scenes we mentioned earlier. All of this led to quite significant colour reproduction errors – in extreme cases, the delta E value exceeded 7, while the threshold for visibility of errors for the human eye is about 3. This situation can be improved through calibration, and you can read about its effects below.

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.

The Dutch manufacturer offers quite a large dose of settings in its products, so as usual, we decided to tinker with them a bit. The effects are immediately noticeable – we managed to correct the white balance, which made the image cease to appear overly pinkish. The brightness characteristics were also partially equalised, of course within the limits that the television itself allows. The picture is no longer so excessively brightened, and the overall reception after calibration is definitely better than in the factory settings of the Filmmaker mode.

You could only nitpick about the characteristics of the EOTF curve, which still indicates that the image tends to brighten HDR content. Despite our efforts, the darkest parts of the scenes can still be too bright, and the brightest ones do not always reach their full contrast potential. However, it must be clearly stated that we are dealing with a typically budget-oriented design – one cannot expect reference-quality rendering of HDR content from it.

Calibration has definitely helped this model – it improved the balance, toned down the aggressive colour palette, and brought the image closer to what one can expect from a well-configured movie mode. However, there are certain limitations that cannot be overcome.

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.

Philips PUS8560 offers a deinterlacing function, hidden under the name “distortion reduction”. And while it indeed serves its purpose, smoothing out problematic tonal transitions, it operates a bit too broadly. In practice, it affects not just colourful gradients but also softens faces, clothing textures, and furniture surfaces. This undermines the authenticity of the image – especially in films where natural texture is of great importance. However, if someone is looking for smoothing at any cost, it’s best to set this option to “Low”. For cinema image enthusiasts – we definitely do not recommend it.

On the plus side, the quality of scaling older materials is worth noting – the PUS8560 model handles them surprisingly well. The image retains a natural softness without artificially boosted sharpness. It’s also worth mentioning that the TV correctly displays very low-resolution content, avoiding issues with image cropping (so-called overscan).

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.

The Philips PUS8560 is a television equipped with a 60 Hz refresh rate panel, which already limits its capabilities for displaying dynamic content right from the start. Watching sports or playing on a console is not one of the more enjoyable experiences. The situation is further worsened by the absence of any option to improve film fluidity. In the menu, you won’t find settings that would allow for the activation of motion smoothing or even a slight motion blur for films recorded at 24 frames per second. You can imagine the effect. The image can appear choppy, especially in shots with panoramic camera movements.

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.

Although the Philips PUS8560 is not designed with gamers in mind, the manufacturer has equipped it with a few features that may prove useful when connecting a console. Onboard, we find automatic switching to game mode (ALLM), as well as a simple connection status information bar – the so-called Game Bar. It doesn't make a particularly visual impression, but it serves its purpose. The presence of variable refresh rate (VRR), operating in the range of 48 to 60 Hz, may come as a surprise. This is not a wide range, but for less demanding games or titles with unstable frame rates, VRR can help reduce the tearing effect. However, this is the only element that can be considered beyond the minimum.

It must be clearly stated that the PUS8560 is not equipment for gamers looking for a responsive screen and full support for modern console features. It lacks HDMI 2.1 ports, the refresh rate is limited to 60 Hz, and the panel's response time is not among the fastest. This model may at best suit people who play occasionally and want to enjoy the Ambilight system.

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.
