Philips PUS8209 vs Haier K85F

Unfortunately, this is where the problems begin. A maximum brightness of 280 nits is definitely too low to feel the true effect of HDR. In practice, the image resembles standard SDR more, so it’s hard to speak of deeper visual experiences. On the positive side, the colour gamut coverage is commendable – 91.4% DCI-P3 is a score that will be sufficient for most films. It must also be said that the image is stable and there are no issues with sudden changes in brightness or colours. Overall, HDR on this television is more of a formality than an actual added value. If we are looking for genuine HDR thrills, this model may not meet expectations.

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.

Philips PUS8209 offers many picture modes, but the best of them, without a doubt, is the Filmmaker mode. Despite its proud name, it has its clear problems. In the case of HD content, the white balance is characterised by a strong dominance of red, which causes the picture to be significantly warmer than it should be in reality. The brightness characteristic (gamma), although correct in the mid-tones, has serious issues at the beginning and end of the curve. Drops in the shadows cause a loss of detail in the dark areas, and blowouts in the bright areas make some elements look unnatural.

For high-quality 4K HDR content, the situation reverses. In this case, blue dominates, leading to an artificial enhancement effect, reminiscent of unnatural retail settings. Such an image looks unattractive and inconsistent with the creators' intentions. An additional problem is the EOTF curve, responsible for brightness in HDR materials. It deviates significantly from the reference chart, causing the image to appear too dark, robbing the depth and detail of HDR content.

Against this backdrop, errors in the Color Checker test and deviations in colour palette reproduction are exceptionally large, which further negatively impacts the overall image quality. The Filmmaker mode, although the best among the available options, requires substantial corrections to fully convey the director's vision.

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.

After calibration, the white balance for HD and 4K content has significantly improved. Although we have not achieved a perfectly flat characteristic, the effect is definitely better than before. The picture on the television no longer appears artificially warm or excessively cold, which significantly enhances the naturalness of the displayed content. The brightness characteristic (gamma) has also been adjusted – the biggest issues at the beginning and end of the graph have been mitigated. The EOTF curve, responsible for brightness in 4K HDR material, has been stabilised, eliminating problems with excessive dimming of the image. In the colour palette test, some imperfections can still be noticed due to average coverage of the wide colour gamut, which is a limitation of the equipment itself. Nevertheless, the final effect is clearly better than before calibration – the image looks more natural and approaches the expectations of the Filmmaker mode.

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.

The television offers a "Distortion Reduction" feature that effectively improves the gradation of tonal transitions, especially when set to the minimum level. Unfortunately, this comes at a cost – the feature simultaneously smooths out details such as the texture of materials. On the positive side, it is worth noting that the operation of this option does not negatively affect film grain, which remains intact.

As for image scaling (upscaling), the television generates a plastic, soft image that generally looks pleasant. However, in the background, one can sometimes notice issues with aliasing on certain elements, such as branches or fine details, which can lower the quality of reception. Despite these minor imperfections, the overall experience of scaling is satisfactory.

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.

The 60 Hz panel in the Philips PUS8209 is mainly suitable for watching films, but there is still a sense of something missing. The television does not offer any motion smoother that would allow users to adjust the fluidity of the picture to their individual preferences, which can be disappointing for some users.

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.

The Philips PUS8209 offers basic features useful for gamers, such as variable refresh rate (VRR), automatic low latency mode (ALLM), and a Game Bar that makes managing settings easier.

Unfortunately, due to the 60 Hz panel, the television will not meet the expectations of more demanding gamers who are counting on higher smoothness and image precision. Additionally, this model does not support any HDR mode dedicated to gaming, such as HGiG or Dolby Vision, which further limits its capabilities in this regard.

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.
