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 HDR effect. In practice, the image resembles standard SDR more, so it's hard to speak of deeper visual experiences. On the plus side, the color gamut coverage is commendable – 91.4% DCI-P3 is a result that will be sufficient for most films. It must also be noted that the image is stable and there are no issues with sudden changes in brightness or colors. Looking at the overall picture, HDR on this TV is more of a formality than an actual added value. If we are looking for true HDR emotions, this model may not meet expectations.

Now let's move on to one of the hottest topics in the world of televisions, which is 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 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 this means – such a value is okay for watching standard SDR materials, but it is absolutely insufficient to show any real benefits of HDR. The image simply lacks the "power" to generate bright, striking bursts. All our measurements and tests on specialist patterns only confirmed this. As if that weren't enough, the television also struggles with color reproduction. In this budget model, we won't find any technologies that expand the color palette, such as quantum dot layers (known in marketing as "QLED"). As a result, the coverage of the DCI-P3 color space, which is crucial for HDR materials, is only about 80%. In practice, this means that the image will not only be dark but also devoid of vibrant, saturated colors that the director wanted to show us.

Philips PUS8209 offers many picture modes, but the best among them, without a doubt, is the Filmmaker mode. Despite its proud name, it has its clear issues. In the case of HD content, the white balance is characterized by a strong dominance of red, causing the image to be significantly warmer than it should be in reality. The brightness characteristic (gamma), although correct in the midtones, has serious problems at the beginning and end of the graph. Drops in the shadows lead to a loss of details in dark areas, and highlights in bright areas make some elements look unnatural.

For high-quality 4K HDR content, the situation reverses. In this case, blue dominates, leading to an effect of artificial image enhancement, reminiscent of unnatural store settings. Such an image looks unappealing 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, making the image appear too dark, robbing the depth and detail of HDR content.

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

Well, how does the television perform with colors straight from the factory, without any intervention from our side? The Haier K85F offers a full range of picture modes, such as Dynamic or Eco, but for anyone who wants to watch movies according to the creators' intentions, only one really matters: Film mode. This is the mode we focused our tests on, and unfortunately, its name has little to do with reality. The picture in the factory settings is far from what we could call cinematic fidelity and requires many adjustments. Let's start with the white balance, which has a clear lack of red color. In practice, this means that the whole picture has a cool, bluish tint. The situation is even worse when it comes to brightness management, specifically gamma curves (for SDR) and EOTF (for HDR). Their graph resembles a real rollercoaster, which has a disastrous effect on the viewing experience. This results in unnatural dimming of SDR content, causing details in the shadows to get lost, and in the case of HDR – excessive brightness, which further exacerbates the issue of highlights. This combination, meaning too cool white combined with chaotic brightness and excessive blue color saturation, causes enormous errors in color reproduction. Our measurements on a specialized ColorChecker chart showed errors (Delta E) regularly reaching and exceeding values of 8-9. In simpler terms: errors above the threshold of 3 are easily noticeable to the naked eye, so such a result means that the colors on the screen are simply heavily distorted.

After calibration, the white balance for HD and 4K content has improved significantly. Although we did not achieve a perfectly flat characteristic, the effect is definitely better than before. The image on the television no longer appears artificially warm or overly 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, which is responsible for brightness in 4K HDR material, has been stabilized, eliminating problems with excessive dimming of the image. In the color palette test, some imperfections can still be seen due to average coverage of a wide color gamut, which is a limitation of the hardware itself. Nevertheless, the final effect is clearly better than before calibration - the image looks more natural and approaches the expectations for the Filmmaker mode.

Well, is there anything we can do about this image? Can professional calibration save the situation? The answer is: both yes and no. It must be clearly stated that there are certain things we cannot overcome. The limitations of the construction itself, namely a poor panel and its narrow color coverage, mean that you can forget about achieving meaningful HDR – we won’t sugarcoat it for you. The biggest beneficiary of our adjustments is undoubtedly the SDR mode, and it is precisely for watching such content, after calibration, that this television begins to make sense. We managed to tame the white balance in our own way. Although the TV only offers basic 2-point adjustment (instead of precise 20-point), it’s not perfect, but we successfully eliminated that unpleasant, cold "chill" in the image. Above all, however, we recorded 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 TV can finally display images without artificially dimming or brightening them. The conclusion is simple: even in the case of such a cheap television, professional adjustment of the settings can achieve a lot and draw out its maximum potential.

The television offers a "Distortion Reduction" feature that effectively improves the gradation of tonal transitions, especially when set to the minimum level. Unfortunately, it comes at a price – the feature also smooths out details like the texture of materials. On the plus side, the operation of this option does not negatively affect the 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 some elements, such as branches or fine details, which can lower the quality of the reception. Despite these minor imperfections, the overall experience of scaling is satisfactory.

Let's move on to digital processing and image scaling, that is, how the Haier K85F handles lower resolution signals, for example, from standard television. Right from the start, we encounter an extremely annoying and completely incomprehensible issue – the overscan feature is enabled by default. This means that the television artificially enlarges the image, cropping its edges, and this occurs on every source, even 1080p. To see the full frame, you have to dig into the screen settings every time and manually switch the format to "stretch to 16:9." It's a detail, but incredibly frustrating. The scaling of content to 4K resolution can be described in one word: acceptable. And that's basically it. The image processor does not strip the image of details, nor does it generate jagged edges or other artifacts. It simply does its job, without any fireworks. It's fine, but nothing more. The biggest and most noticeable shortcoming in the digital processing section is the absence of a banding smoothing function. This is an algorithm that could significantly reduce the annoying banding effect we mentioned earlier. Unfortunately, the manufacturer did not implement such a solution, condemning us to watch the imperfections of the panel and low-quality materials in all their glory.

The 60 Hz panel in the Philips PUS8209 is mainly suited for watching movies, but there is also a certain sense of dissatisfaction here. The TV does not offer any motion smoothing feature that would allow adjusting the smoothness of the picture to individual preferences, which may be disappointing for some users.

The panel in the K85F model operates at a native refresh rate of 60 Hz, which already sets certain expectations for smoothness of the image right from the start. However, we must admit that we were very positively surprised when we found not one, but two separate sliders for motion control in the settings menu: one labeled "Blur Reduction" and the other "De-Judder." Such generosity in this price segment is an absolute rarity, as usually manufacturers offer at most one common option. Unfortunately, our enthusiasm quickly dwindled as fast as it appeared. It soon became clear why Haier was so "generous" – the slider responsible for blur reduction is simply a dummy. Moving it does not produce any visible effect on the screen; thus, only one of the two options actually works.

The Philips PUS8209 offers basic functions 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 fluidity and precision of the image. Additionally, this model does not support any HDR mode dedicated to games, such as HGiG or Dolby Vision, which further limits its capabilities in this regard.

Let's move on to the features for gamers, although we must point out right away that this is more of a proposal for "casual" players. 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 gimmick. 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 most important advantage. That's a shame. (That’s why we mark it as HDMI 2.0 ports in our tests). Another oddity is the television's response to attempts to calibrate HDR from the console. Changes in brightness settings cause very unnatural behavior of the image, which might suggest an incorrect implementation of the HGiG standard. To be honest, however, you shouldn't worry too much about this, because as we have mentioned multiple times, we simply do not recommend using any HDR content on this screen. However, to make it not so bitter, 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. Although it works in a very modest range of 48-60 Hz, its very presence is commendable. Thanks to this, the image in games can stutter less, which truly improves the gaming experience.
