Sony Bravia 8 MK2 vs Haier K85F

Thanks to the new QD-OLED panel, the Sony Bravia 8 II can achieve astronomically high brightness levels of around 2000 nits, translating into nearly reference-quality for films and series recorded in HDR format. In test materials such as Life of Pi and Sicario 2, the effect is truly captivating – details in bright areas of the image remain perfectly visible, and night scenes enchant with depth and contrast. However, it is not perfect. Compared to its fiercest competitors, the Bravia 8 II shows a noticeable drop in brightness during full-screen, very bright scenes. When comparing maximum peak luminance with 100% white brightness in HDR mode, the Bravia 8 II appears even two or three times dimmer than LG G5 or Samsung S95F models. This was especially evident in a scene from the film The Meg – the screen became noticeably darker than in competing televisions. Despite this shortcoming, the results of the Bravia 8 II still place it among the top of the market. It deserves praise for its absolutely top-tier colour gamut coverage – nearly 100% DCI-P3 and close to 90% BT.2020. These parameters allow for fully extracting the potential of HDR content and providing experiences akin to those in a cinema within the comfort of home.

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.

Straight out of the box, the Bravia 8 II performs quite well. In the best IMAX® Enhanced mode, the television is able to render colours in a pleasant and natural way, although “good” doesn’t mean “best in class” here. The white balance definitely needs adjustment – skin tones tend to lean towards slightly pink/cool hues, both in SDR and HDR materials. We also noticed that the characteristic of the EOTF curve reveals a certain tendency to brighten the darkest parts of the image. This is probably due to the manufacturer’s desire to highlight as many details as possible even in deep shadows. Is this a good approach? It’s hard to say definitively, but we know one thing – it is not an ideal solution.

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.

After calibration, the excessive cooling of the image caused by an overly strong boost of the blue colour was mainly eliminated. The reds have become deeper, and skin tones have taken on a natural, healthy appearance. The actors, who previously seemed "cold," now look much livelier and more convincing on screen. However, one thing has not changed – the analysis of the EOTF curve still shows that the Bravia 8 II has a tendency to brighten the darkest areas of the image. It is difficult to determine whether this is a deliberate method used by the manufacturer or a result of the panel and software design. In practice, this means that scenes which the creators intended to leave in deep darkness can reveal more details than anticipated. Despite this, the image quality after calibration is clearly improved – warm, natural colours and realistic skin tones make viewing on the Bravia 8 II simply more pleasant to the eye.

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.

Upscaling and digital image processing are a true showcase of the capabilities of the Bravia 8 II. Sony has long been regarded as a master in this field, and here it only reaffirms its reputation. The proprietary XR processor can extract nearly the maximum from lower-resolution materials – whether it's television or an old DVD film, the image appears clearer, with more detail and better depth. Of course, if we feed it exceptionally low-quality material (like our archival photo with the Model), it won't work wonders, but in everyday viewing, it's hard to find fault with it.

The gentle gradation feature also performs excellently. In the "Medium" setting, it effectively smooths tonal transitions, eliminating banding in coloured and grey gradients, while not destroying the film grain or fine details in the image. It is this balance between subtlety and effectiveness that keeps Sony televisions among the best on the market in this category.

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 smoothness of motion is practically a closed topic in the case of the Bravia 8 II. The OLED with a refresh rate of 120 Hz naturally provides a very clear, sharp image in dynamic scenes, so it's hard to complain about anything here. However, one of the best motion smoothing systems on the market truly deserves special praise. They allow precise adjustment of film smoothness to one’s own preferences – from gentle smoothing to almost a “theatrical” effect – without the risk of artificial jumps, tearing of the image, or annoying artifacts. This is one of those features that will be appreciated both during movie screenings and while watching sports.

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.

Sony has really learnt its lessons from previous years and in the Bravia 8 II has prepared a package of features for gamers that is hard to describe in any other way than "almost perfect". We have everything you'd expect from equipment of this class – VRR, ALLM, Dolby Vision Gaming mode, HGiG, and even a handy Game Bar that allows you to quickly preview parameters and change settings without leaving the game. It's also worth noting how smoothly and seamlessly these features work – no delays, no strange stutters. You simply start the game, and everything looks as it should. Unfortunately, there are a few "buts". The manufacturer still only provides us with two full-bandwidth HDMI ports, so if someone has a console, PC, and another device such as a soundbar connected via eARC, it becomes a hassle of switching cables. It is also surprising that there is no support for 1440p resolution at 120 Hz – particularly important for Xbox gamers. Overall, however – this is one of those televisions that can easily be placed in the centre of a gaming lounge and enjoyed without significant compromises.

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.
