Philips OLED769 vs Haier K85F

Philips OLED769 performs quite well, particularly in film scenes with small points of light. The television surprises with its brightness, reaching around 800 nits, which is an impressive result. As a result, fine sources of light, such as street lamps at night or stars in the sky, are sharp and full of detail. However, the biggest challenge for this model is the scene with a full-screen burst of sunlight. In such moments, the brightness drops to about 250 nits, which is not very impressive. This is a typical problem for cheaper OLED displays, which struggle to maintain high brightness across the entire screen surface.

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.

The "Film" mode proved to be the best factory setting in terms of fidelity to the source material, and it is on this that we based our tests. However, like other factory modes, it was not without flaws. Let us examine, therefore, what exactly went wrong in SDR and HDR materials.

In both cases, the white balance was disrupted by the excessive dominance of green and red hues. This phenomenon created a yellowish tint that spread across the entire image, leading to issues such as yellowed whites and unnatural skin tones. These problems were clearly highlighted on the "ColourChecker" palette, where each of the samples was shifted towards warmer tones.

As for contrast and brightness, in the Philips OLED769, we can look at two key graphs: Gamma for HD content and the EOTF curve for 4K HDR content. In the case of the first graph, the gamma value falls below the optimal level of 2.4, resulting in an increase in brightness of light areas of the image. This means that bright elements may be slightly overexposed, losing detail and depth. In contrast, the EOTF curve for 4K HDR content performs really well. The graph shows that the television effectively conveys details in both the brightest and darkest areas of the image, resulting in a realistic and dynamic representation of scenes.

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 professional calibration, Philips OLED769 truly shines in terms of colour accuracy. The television has been completely stripped of any yellow tint in both HD and 4K content. The Colour Checker test confirms that deltaE errors are minimal, occasionally exceeding a value of 2, which means we can speak of almost perfect director's representation.

When it comes to contrast, the situation is equally impressive. With 4K materials, there wasn't much to improve initially, while the gamma chart has been significantly enhanced. This allows dark and light areas of the image to be represented with greater accuracy, resulting in a realistic and dynamic portrayal of scenes.

The calibration has allowed the full potential of this television to be unleashed, both in terms of colours and contrast. Philips OLED769 now offers vivid, natural images of high quality that will delight any user, whether they are watching films or using other multimedia.

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.

When it comes to lower quality materials, the distortion reduction in the Philips OLED769 handles tonal transitions well, especially at the minimum setting. It is worth noting that at this setting, film grain is not blurred, which is a pleasant surprise, as such negative phenomena often occur with other manufacturers. Overall, it is quite a decent solution. However, it should be pointed out that this setting does not work in HDR mode, where gradation issues are much more pronounced. In HDR mode, the television struggles with smoothing tonal transitions and may present more noticeable distortions and noise, reducing picture quality in dynamic scenes.

Regarding digital processing, the Philips OLED769 performs well. The model in the photo is not overly jagged, and the branches in the background lack the characteristic jagged edges. The television achieves this effect thanks to the absence of artificial sharpness, which may be an advantage for some users. Others, however, may find this less attractive, as they prefer a more vibrant, sharper image instead of a subtle effect. This effect can be mitigated by using a higher setting for the "Sharpness" parameter.

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.

Philips OLED769 features a multi-stage motion smoother called "Motion Style", which will satisfy users who appreciate the ability to customise the fluidity of motion in films. With this function, you can set the image to be more frame-like or smooth, resembling a theatrical effect. This is a great solution for those who want to adapt the displayed content to their visual preferences. Gamers will also not be disappointed, as the television, like most OLEDs, is equipped with a 120Hz panel. This provides exceptional fluidity and dynamism of the image. Unfortunately, Philips OLED769 does not have the BFI (Black Frame Insertion) feature, which could further improve motion fluidity and sharpness. Despite this limitation, the television still offers excellent visual experiences for both cinema lovers and gamers. This is definitely one of its strong points.

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.

Philips OLED769 has been designed with gamers in mind, offering full compatibility with consoles and the highest quality of gameplay. The television received the maximum rating in this category, providing everything that the heart desires. With HDMI 2.1 ports fully supporting ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate), the television ensures smooth and hassle-free gaming. ALLM automatically switches the television to low latency mode, while VRR eliminates stuttering and screen tearing, resulting in fluidity and stability in gaming. The Dolby Vision gaming feature is another advantage, although it only works at a frequency of 60 Hz. Most casual gamers will likely not feel the lack of a higher frequency; however, more demanding users may have some reservations. This allows for enjoyment of a dynamic range of tones and realistic images, enhancing the gaming experience. PC gamers will also not be disappointed, as Philips OLED769 offers full compatibility with Nvidia graphics cards, thanks to support for G-Sync. This technology synchronises the refresh rate of the television with the graphics card, eliminating tearing and stuttering, resulting in excellent image fluidity.

Philips OLED769 is a television that perfectly meets the needs of gamers, offering a wide range of advanced features and technologies that significantly enhance gameplay quality and user comfort.

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.
