Philips PML9009 / 9019 / 9059 vs Haier K85F

Philips PML9009 doesn't really operate at the highest values in HDR materials. Most effects with brightness around 550 nits won't leave us thrilled with the lighting effects, although they are quite stable, which is a plus, and a considerable difference can be felt between SDR materials. It's worth noting that we can achieve a good result only in one scenario, that is in the film "Gemini," where the flashlight as the sole light source can really shine. Why in this scene? The answer is quite simple. The scene itself doesn't have a large amount of black, and the flashlight isn't as large an object as the sun in the first and last scenes. Overall, the brightness measurement results in HDR materials aren't a solid basis for recommending this television for viewing productions that use a wide color gamut. However, it's worth mentioning that this model can cover it in a not too bad 93% degree in the case of the DCI-P3 palette.

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.

The best factory mode used during our tests was "Filmmaker". Here, we will examine both SDR and HDR content. The key differentiator is primarily the EOTF curve in the wide colour gamut materials and gamma in those recorded "the old way". Starting with SDR films and series and the most basic thing we can observe, which is white balance, we see a significant red colour dominance. This led to a yellow tint across the whole image, causing unnaturally looking faces and yellowed whites. This issue is also clearly visible on the "ColourChecker" palette, where all colours have shifted towards their warmer counterparts. Looking at an even more significant graph, the gamma responsible for the contrast of the image, we see considerable errors beginning right from the start. From the left, the value we measured, indicated by a combined ellipsis, clearly spiked upwards, causing complete merging of details in the darkest scenes. This state of affairs persisted up to 10% brightness on the screen, after which it dove below the reference orange line, leading to a deterioration in contrast, which, as we know, Philips PML9009 is already lacking. In HDR materials, white balance issues were very similar to those in SDR content. The discrepancy appears when checking the EOTF curve, which governs the rate of brightness increase and severely limited it, resulting in an unnaturally dark image. As for the colours themselves, there were more reasons for concern here, as the television's low luminance caused a huge disparity between the actual state and the correct one, which is perfectly visible on the error graph, often exceeding the scale.

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.

Philips PML9009, like most leading manufacturers, has been providing advanced tools for calibration processes for years. Here we find 2-point and 20-point greyscale adjustments, as well as an advanced CMS (Color Management System). The differences resulting from calibration are evident, and even someone who doesn't pay attention to image quality (although there probably aren't many like that here) will notice the positive difference. Both SDR and HDR materials have undergone quite a transformation. The former and the latter have primarily shed the ugly yellow tint resulting from the red colour dominance in white balance. As for the SDR materials and gamma, although it is not perfectly modelled and still loses dark details, the rest of it is at more than a decent level, and minor errors will not be noticeable. The colours themselves look far better, and with low deltaE errors, they are almost reference-quality. On the other hand, HDR materials, due to the unit's low luminance, have not been optimised as we would have liked. Although the white balance has been largely normalised, a slight blue tint can still be observed here and there. Fortunately, the EOTF curve turned out to be much more accessible, allowing for practically perfect geometry. Unfortunately, due to the screen's too low brightness, the colour errors remain quite high.

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.

Judging by how PML9009 Philips handled tonal transitions, the image scaling test should perform just as well. This time, we are checking the TV’s algorithms responsible for enhancing the quality of images that were recorded in lower quality. Such images can be found, for example, in various TV shows or older films. In this regard, Philips PML9009 performs quite mediocrely and drastically blurs the image. This is particularly noticeable on fine branches or the model's hair.

Let’s revisit the issue of tonal transitions, which performed remarkably well. Within the unit, we will find several levels of smoothing. Even the lowest one can effectively eliminate any jerky tonal transitions and will be suitable for the vast majority of materials. More importantly, none of the settings for this function soften the effect of film grain, which is extremely important in terms of alignment with the director's vision. However, we would like to point out that sometimes it may turn out that fine details are blurred.

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.

Philips PML9009 has been equipped with a panel that has a native refresh rate of 120 Hz. This is the essential minimum for watching all kinds of sports and is recommended for comfortable gaming in favourite titles on consoles or PCs. The manufacturer, for those who dislike the characteristic judder of footage recorded at 24 fps or those requiring a high degree of motion smoothness, such as when watching football matches, has prepared an effective system for improving the sharpness of moving images. In the dedicated tab, we will find a "Smoothness" slider responsible for eliminating judder and a "Motion Blur Reduction" setting that helps to increase the sharpness of dynamic elements. The function works very well and granularly, meaning each setting has a real impact on motion perception. With such a set, every user will find their sweet spot. In the picture, we present our choice, which is slight smoothing without the soap opera effect.

A matter directly related to motion is the response time of the pixels in the panel itself. The best in this regard are of course OLED panels, followed by units based on IPS and ADS screens, and lastly VA. Despite the generally good quality of the systems responsible for smoothening the image, the use of a VA panel carries consequences in the form of black smear behind fast-moving objects. Although in the tested television this should not occur frequently, it will be noticeable here and there.

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 PML9009, equipped with HDMI 2.1 connections with full bandwidth, supports all functions dedicated to gamers. The most basic ones, such as VRR and ALLM, are a given, but G-Sync, FreeSync, or playing in HDR Dolby Vision with low input lag are not. These features activate without any problems, and during the tests conducted, they presented no obstacles. Such preparation of the television is certainly its strong point, and it can be said that it is a unit dedicated to gamers. For more advanced users, we also mention that the PML9009 is equipped with the HGIG mode, which will be particularly felt by gamers, as there are still relatively few games that support Dolby Vision. This mode primarily allows for the adjustment of HDR effects to the capabilities of the television on a special board, to prevent dimming and burning of the image.

The television additionally implements a special menu - GameBar. This allows for editing unit settings "on the fly," meaning without having to exit the game. In it, we will also find functions such as activating a crosshair or black level correction for better visibility of opponents in shadows.

In a brief summary of this paragraph, the Philips PML9009 is a unit that will undoubtedly attract gamers' attention. Thanks to its versatility, it will allow for playing any title in the highest quality without compromises. Especially since features such as VRR, ALLM, G-Sync, FreeSync, or gameplay in HDR Dolby Vision will provide an even greater immersion in the favourite title.

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.
