Haier K85F vs Philips PUS7000

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.

Unfortunately, the PUS7000 is not suitable for watching HDR content. This screen is simply too dark. A brightness level of 200 nits is insufficient to display this format correctly. Even if a HDR signal message appears on the screen, the image will resemble a standard SDR recording. Therefore, it’s better to stick with the latter format to avoid errors in displaying bright scenes, as you will read below. The situation is worsened by the fact that this is a classic LCD model without additional layers that improve colours, such as QLED or PFS. As a result, colours in HDR may seem washed out. Ultimately, this provides a worse effect than in the standard SDR format, which is simply better suited to the capabilities of this panel.

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 tested the television in movie mode, which theoretically should provide the best and most natural colours. And indeed, this mode is quite correct; however, when we connected the calibration equipment, its biggest flaw became apparent. The PUS7000 has significant shortcomings in displaying reds. Poorly tuned white balance and too low saturation of this colour cause the image to appear too cool. As a result, one might get the impression that the displayed content lacks vibrant colours. The situation is worsened by the fact that both SDR and HDR content are excessively brightened. This is confirmed by the gamma curve and EOTF graphs, which show that the television displays the image brighter than it should. This causes scenes to lose their depth and can make them seem slightly washed out. Fortunately, in the Philips menu, we find plenty of features to improve these aspects, so we immediately proceeded to calibration to see what we could extract from this screen.

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 professional calibration, it’s evident that the PUS7000 responds well to image adjustments. In this price range, that’s not a given. The effects are best evaluated in two scenarios, depending on the content we plan to watch. SDR performs the best. After our adjustments, the image looks really good. Most colour errors have dropped below level 3, which is the threshold at which discrepancies usually become visible to the naked eye. Movies, series, sports, and regular television present naturally, without unpleasant deviations. If someone mainly watches classic channels or streams in HD quality, the difference after calibration will be noticeable straight away. However, it must be said clearly that the PUS7000 is still not a television suited for proper HDR, and calibration doesn't change much in this regard. The reason lies in the hardware: colours remain too unsaturated. The television lacks solutions that widen the colour gamut, such as PFS filters or a quantum dot layer, so the panel simply cannot display the intense colours required by HDR. This is most evident in reds, which still look washed out. This limitation cannot be circumvented through menu settings, as it stems from the design of the backlighting and the panel itself.

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 PUS7000 handles digital image processing quite well. The distortion reduction feature deserves praise, as it effectively smooths unwanted tonal transitions even at a low setting. However, it has its downside: with too aggressive operation, it can introduce undesirable artifacts on the screen. It would be a good idea to experiment with this setting to find the golden mean between a smooth image and the clarity of details.

The upscaling, or enhancing the quality of lower materials to 4K, is decent. The image after processing is very "soft," which is typical of almost all Philips TVs. The edges are plastic and smooth, making the image look cohesive. If someone finds it too soft, it can always be adjusted with the sharpness slider in the menu for a more pronounced effect.

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.

In this regard, we actually have no good news. It might seem that the biggest downside is the lack of a 120 Hz panel, but in this price range, that's actually the norm, and it's hard to expect more. However, the worst part is that the television has no motion smoothing features. There are no supporting systems in place for either movies or sports. We have to come to terms with the fact that the image on the PUS7000 is processed "raw." This means that during dynamic scenes or fast camera movements, motion can appear choppy or unclear. We have no option to enable any smoothers that could alleviate this effect.

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.

Even though the PUS7000 isn’t marketed as a gaming TV, it doesn't perform as poorly in this category as one might expect. True, it doesn't support 120 Hz refresh rates, which is understandable at this price point, but the manufacturer has included several important features that significantly improve the console gaming experience. The most important of these are VRR and ALLM technologies. VRR is responsible for synchronising the screen with the number of frames generated by the console. This means the image doesn't "tear" and remains consistent even during sudden drops in frame rates while playing. On the other hand, ALLM is a solution that automatically switches the TV to a mode with the lowest latency immediately after detecting a signal from the console. All these parameters are easily accessible thanks to the Game Bar feature. This is a special control panel for gamers that can be brought up on the screen at any time. It allows for a quick view of current settings and connection status without interrupting gameplay, which is a very convenient solution.
