Haier K85F vs Haier Q80FUX

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.

Alright, let’s move on to the topic that stirs up so much discussion, namely the capabilities of the television in HDR mode. Let’s state it clearly right away: the Haier Q80FUX is certainly not a brightness demon. The panel of this receiver can generate about 350 nits at peak, which in today’s terms is the absolute minimum to even talk about the presence of High Dynamic Range (HDR). On the positive side, this power is at least stable – regardless of which test pattern or film scene we used, the measurements consistently oscillated in the range of 300-350 nits. These are therefore results that are at best sufficient, definitely far from the dazzling display of capabilities we are accustomed to with more expensive models. Fortunately, there is one aspect in which the Q80FUX compensates for these shortcomings and does so impressively. After all, we are talking about a QLED television (more precisely PFS LED), which means that thanks to the quantum dot filter applied to the panel, it can generate really juicy, vibrant colours. These are not empty promises – a DCI-P3 colour gamut coverage of nearly 95% is an impressive result and directly translates into colours that are very pleasant to the eye and saturated.

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.

Factory settings for movie mode are rarely perfect, but in the case of the Q80FUX, we were confronted with a noticeable imbalance. In SDR content, the image was decidedly too warm, a result of excessive red in the white balance, giving the whole a slightly sepia tone. Ironically, in HDR materials, the television fell into the opposite extreme – an excess of blue caused an unnatural, cold effect in perception. However, it was not the capricious white balance that was the biggest problem with this television. The real culprit, responsible for the aforementioned issues, was hiding deeper. It turned out that the Q80FUX has completely miscalibrated gamma values and, crucial for HDR, a poorly executed EOTF curve. It was these erroneous factory settings that caused persistent clipping of the brightest parts of the image, overlaying them with that characteristic milky filter. Thus, we found the source of the problem. This state of affairs led to general, significant colour errors, which were easy to catch even for an untrained eye. Like every television we tested, we decided to calibrate this model as well, and the results of these adjustments can be found in the next paragraph.

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 results of our calibration procedures must, regrettably, be acknowledged as twofold. Generally speaking, the picture is undeniably better than before the corrections; however, the biggest winner of this process turned out to be SDR content. It is precisely there, after correcting the gamma and white balance graphs, that we achieved results that can confidently be called very good. After adjustment, the Q80FUX truly shines in standard dynamics, showing only slight errors in the most difficult skin tone reproductions. Unfortunately, the weakest link remains HDR content. Here lies the paradox: despite having calibrated the white balance to nearly perfection, the overall colour errors still remain at quite a high level. The reason is that the television continues to interpret static HDR10 metadata "in its own way," stubbornly enforcing that unfortunate image burn-out effect, which inevitably leads to significant distortions. Although we have successfully eliminated the factory excess of blue, it is precisely due to this interference of electronics that the screen still tends to stray into somewhat overly cold tones. That is just how this television is.

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.

If there is one area where Haier clearly shows it still has a long way to go compared to the market leaders, it is digital image processing. The upscaling, well... is just alright. And that’s really about all that can be said about it. It does what is expected of it: it ensures that lower resolution signals do not scare us with harsh pixelation on the screen and do not look like a forcibly enlarged postage stamp. However, it is far from the finesse and “intelligent” sharpening that more experienced players in this market have developed over the years. The biggest shortcoming of the Q80FUX software is the almost complete lack of any additional "cleaning" and smoothing functions for the image. The receiver does not offer any noise reduction or gradient improvement mechanisms. This means that with older or heavily compressed materials, we simply have to come to terms with the fact that any imperfections in tonal transitions or blending of colours, which we mentioned earlier, will continually accompany us during the viewing.

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 issue of motion fluidity and blurring is largely predetermined by the use of a 60-hertz panel, which naturally makes it difficult to recommend this receiver to enthusiasts of very dynamic content. Fortunately, in the Q80FUX, we find a few options (although, as we shall see shortly, in reality only one) that are supposed to improve the experience with older film productions. There is a "De-Judder" slider available, which actually controls the smoothness of the image and allows us to adjust it to our preferences: from raw, cinematic frame rates to a more theatrical, smoothed presentation. However, a true surprise awaits us just beside it in the menu. There is also a second slider, supposedly dedicated to removing blur – a feature we typically encounter in 120Hz panels to combat motion blur in sports. However, as we expected, recalling memories from the tests of the K85F model, this slider here is merely a façade. Its adjustment does absolutely nothing to the image and it simply appears to be an oversight by the product engineers who left a non-functional option in the software for this type of panel.

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.

Stepping into the realm of gaming, the Haier Q80FUX proves to be quite a decent companion for the "casual gamer". Onboard, we find highly desired features such as VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). However, the biggest surprise is something else altogether. Although we are not dealing with a 4K@120Hz panel here, the television is capable of accepting and displaying a 120Hz signal at a lower resolution (Full HD). This is a very useful feature that allows for a conscious switch of the console to a lower resolution mode in exchange for significantly higher smoothness, which is a compromise entirely acceptable in the gaming world.

We won’t particularly complain about the lack of extras like the "Game Bar", as it's merely a nice addition. The most concerning issues arise when we delve into the world of HDR in gaming. Due to the television constantly adapting the signal "in its own way", setting the brightness on the console according to the HGIG standard is nearly impossible to achieve as per instructions. Worse still, in the Dolby Vision mode for gaming, the input lag increases to around 50 ms, which is a value high enough to render this mode practically unusable. However, in general, we would not recommend gaming on this television in HDR mode, so these are not such grave shortcomings. What is most pleasing is the presence of 120Hz in Full HD, which makes the Q80FUX a rather nice television for the occasional gamer.
