Hisense A6N vs Haier K85F

The quality of the HDR effect on A6N unfortunately does not impress. The peak brightness of 250 nits does not allow for spectacular effects, and HDR appears rather dull, resembling more of a regular SDR. This state of affairs will not satisfy more demanding users who wish to enjoy high-quality film materials. Additionally, the coverage of the colour palette is also not very impressive – a DCI-P3 level of 82% is an average result that does not fully allow one to enjoy vibrant colours in HDR materials.

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.

In the category of colour reproduction, the model Hisense A6N in Filmmaker Mode leaves much to be desired. Although the name of the mode suggests that we should expect faithful reproduction of cinematic colours, the reality is different – the television has significant issues with image quality. The problem with white balance is particularly noticeable, both for HD and 4K materials, which is heavily disrupted by the dominance of blue. This results in artificial, cold tones, which can clearly be seen in the comparison photo below. The Colour Checker test further confirms these errors, which are exacerbated by low colour gamut coverage.

The gamma brightness characteristic shows a serious problem in maintaining a level of 2.4 – the graph is significantly below the reference value, which leads to excessive image brightness and washed-out blacks. The EOTF curve for 4K materials also indicates brightness issues – at the beginning, there is a significant spike, which results from the television's excessive brightness, negatively impacting image quality. Such image characteristics do not allow one to fully enjoy watching films and require manual correction.

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.

Hisense A6N offers options and tools in its settings to adjust many image parameters that we have utilized. When it comes to white balance, we managed to eliminate the excess blue colour – this effect is clearly visible in the comparison photo below, where the boy in the image seemingly "comes to life". A significant improvement can also be noticed in the gamma brightness characteristics – the television no longer has serious issues with excessively brightening the entire image. Unfortunately, the same cannot be said for 4K content, where the EOTF curve could not be fully corrected due to the exceptionally low brightness of this model. For HDR materials, we apply dynamic tone mapping, which allows for the recovery of many details despite the boosting of mid-tones in the image. For this television, this provides more benefits than drawbacks. The errors that are still visible in the colour palette test and Colour Checker for 4K materials stem from the low colour gamut coverage and are difficult to eliminate due to the characteristics of the television. Nevertheless, the tonal quality of the image is significantly better, which is why we recommend calibrating the factory settings, which are far from ideal.

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.

Let's check how A6N performs with low-quality materials. When it comes to smoothing tonal transitions, the lack of posterisation reduction or smoothing of tonal transitions in low-quality materials such as television or DVD can be noticeable for more demanding viewers. In terms of digital processing, the model is presented correctly, and the branches are devoid of characteristic jaggedness – the image is very plastic and soft, which may appeal to those who prefer this style of image.

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 Hisense A6N will likely satisfy those who enjoy watching films, as the television offers an "ultra motion smoother," allowing us to adjust the motion smoothness – either more choppy or more fluid, cinematic. When it comes to motion blur, it performs rather average – noticeable blur is evident, especially on dark backgrounds, which is quite a typical feature in this range of televisions.

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.

Hisense A6N is a television that is likely to appeal to casual gamers, primarily due to its 60 Hz panel, which may not satisfy more demanding users. Nevertheless, it offers several features that can enhance the gaming experience. The television supports functions such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and Dolby Vision, which allows for better picture quality and smoother motion in games that support these technologies. Moreover, the low input lag ensures quick reactions in gameplay, which is crucial, especially in dynamic productions. With these features, although the television is not an ideal choice for demanding gamers, it provides solid support for those who appreciate comfortable gaming without complicated settings. It is an ideal solution for individuals who want to enjoy gaming without high hardware requirements while also having access to modern technologies that enhance gameplay quality.

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.
