Philips OLED769 vs Haier K85F

The Philips OLED769 performs admirably in film scenes featuring small bright elements. With peak brightness reaching around 800 nits, the TV handles light sources like street lamps or stars with remarkable vividness and detail. However, its limitations become evident during scenes with full-screen brightness, such as sun glare, where brightness drops to approximately 250 nits. This is a common challenge for more affordable OLED models, which often struggle to sustain high brightness across the entire display.

Now let's move on to one of the hottest topics in the world of televisions, which is 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 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 this means – such a value is okay for watching standard SDR materials, but it is absolutely insufficient to show any real benefits of HDR. The image simply lacks the "power" to generate bright, striking bursts. All our measurements and tests on specialist patterns only confirmed this. As if that weren't enough, the television also struggles with color reproduction. In this budget model, we won't find any technologies that expand the color palette, such as quantum dot layers (known in marketing as "QLED"). As a result, the coverage of the DCI-P3 color space, which is crucial for HDR materials, is only about 80%. In practice, this means that the image will not only be dark but also devoid of vibrant, saturated colors that the director wanted to show us.

The "Film" mode on the Philips OLED769 proved to be the most faithful factory setting for preserving the source material, and it was the basis for our tests. However, like other factory presets, it has a few flaws. Let’s break down the key issues observed in SDR and HDR content.

In both formats, the white balance exhibited a noticeable dominance of green and red tones. This led to a yellowish tint across the image, resulting in yellowed whites and slightly unnatural skin tones. This was particularly evident in the "ColourChecker" palette, where colour samples leaned toward warmer shades.

In terms of contrast and brightness, two critical graphs tell the story: the Gamma curve for HD content and the EOTF curve for 4K HDR content. For SDR, the gamma value dips below the ideal 2.4 level, causing lighter parts of the image to appear overly bright. This overexposure reduces detail and depth in bright areas. In contrast, the EOTF curve for HDR content performed admirably, accurately maintaining details in both bright and dark regions. This ensures realistic, dynamic scene reproduction that enhances the overall viewing experience.

Well, how does the television perform with colors straight from the factory, without any intervention from our side? The Haier K85F offers a full range of picture modes, such as Dynamic or Eco, but for anyone who wants to watch movies according to the creators' intentions, only one really matters: Film mode. This is the mode we focused our tests on, and unfortunately, its name has little to do with reality. The picture in the factory settings is far from what we could call cinematic fidelity and requires many adjustments. Let's start with the white balance, which has a clear lack of red color. In practice, this means that the whole picture has a cool, bluish tint. The situation is even worse when it comes to brightness management, specifically gamma curves (for SDR) and EOTF (for HDR). Their graph resembles a real rollercoaster, which has a disastrous effect on the viewing experience. This results in unnatural dimming of SDR content, causing details in the shadows to get lost, and in the case of HDR – excessive brightness, which further exacerbates the issue of highlights. This combination, meaning too cool white combined with chaotic brightness and excessive blue color saturation, causes enormous errors in color reproduction. Our measurements on a specialized ColorChecker chart showed errors (Delta E) regularly reaching and exceeding values of 8-9. In simpler terms: errors above the threshold of 3 are easily noticeable to the naked eye, so such a result means that the colors on the screen are simply heavily distorted.

After professional calibration, the Philips OLED769 truly excels in colour accuracy. Any yellow tint previously seen in HD and 4K content is now eliminated. The Colour Checker test shows minimal deltaE errors, occasionally exceeding a value of 2, which indicates a nearly perfect representation of the director's intent.

When it comes to contrast, the results are equally impressive. For 4K materials, there was little room for improvement initially, but the gamma curve has been significantly refined. This leads to a more accurate rendering of dark and bright areas, resulting in a dynamic and realistic viewing experience.

Thanks to the calibration, the full potential of the television has been unlocked. The Philips OLED769 now delivers vibrant, natural, and high-quality images, making it an excellent choice for movie lovers and multimedia users.

Well, is there anything we can do about this image? Can professional calibration save the situation? The answer is: both yes and no. It must be clearly stated that there are certain things we cannot overcome. The limitations of the construction itself, namely a poor panel and its narrow color coverage, mean that you can forget about achieving meaningful HDR – we won’t sugarcoat it for you. The biggest beneficiary of our adjustments is undoubtedly the SDR mode, and it is precisely for watching such content, after calibration, that this television begins to make sense. We managed to tame the white balance in our own way. Although the TV only offers basic 2-point adjustment (instead of precise 20-point), it’s not perfect, but we successfully eliminated that unpleasant, cold "chill" in the image. Above all, however, we recorded 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 TV can finally display images without artificially dimming or brightening them. The conclusion is simple: even in the case of such a cheap television, professional adjustment of the settings can achieve a lot and draw out its maximum potential.

When it comes to lower-quality materials, the distortion reduction in the Philips OLED769 does well in smoothing tonal transitions, especially at the minimum setting. It's worth noting that film grain is not blurred, which is a positive surprise, as such negative phenomena often occur with other manufacturers. Overall, this 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 TV struggles with smoothing tonal transitions and may exhibit more noticeable distortions and noise, reducing image quality in dynamic scenes.

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

Let's move on to digital processing and image scaling, that is, how the Haier K85F handles lower resolution signals, for example, from standard television. Right from the start, we encounter an extremely annoying and completely incomprehensible issue – the overscan feature is enabled by default. This means that the television artificially enlarges the image, cropping its edges, and this occurs on every source, even 1080p. To see the full frame, you have to dig into the screen settings every time and manually switch the format to "stretch to 16:9." It's a detail, but incredibly frustrating. The scaling of content to 4K resolution can be described in one word: acceptable. And that's basically it. The image processor does not strip the image of details, nor does it generate jagged edges or other artifacts. It simply does its job, without any fireworks. It's fine, but nothing more. The biggest and most noticeable shortcoming in the digital processing section is the absence of a banding smoothing function. This is an algorithm that could significantly reduce the annoying banding effect we mentioned earlier. Unfortunately, the manufacturer did not implement such a solution, condemning us to watch the imperfections of the panel and low-quality materials in all their glory.

The Philips OLED769 features a multi-stage motion smoother called "Motion Style," which will satisfy users who value the ability to customize motion fluidity in movies. Thanks to this function, the image can be set to be more frame-like or fluid, resembling a theatrical effect. This is a great solution for those who want to match the displayed content to their visual preferences. Gamers will also be pleased, as the TV, like most OLEDs, is equipped with a 120Hz panel. This provides extraordinary fluidity and image dynamics. Unfortunately, the Philips OLED769 lacks BFI (Black Frame Insertion) functionality, which could further improve motion fluidity and sharpness. Despite this limitation, it offers excellent visual experiences for cinema and gaming enthusiasts, one of its main strengths.

The panel in the K85F model operates at a native refresh rate of 60 Hz, which already sets certain expectations for smoothness of the image right from the start. However, we must admit that we were very positively surprised when we found not one, but two separate sliders for motion control in the settings menu: one labeled "Blur Reduction" and the other "De-Judder." Such generosity in this price segment is an absolute rarity, as usually manufacturers offer at most one common option. Unfortunately, our enthusiasm quickly dwindled as fast as it appeared. It soon became clear why Haier was so "generous" – the slider responsible for blur reduction is simply a dummy. Moving it does not produce any visible effect on the screen; thus, only one of the two options actually works.

The Philips OLED769 was created with gamers in mind, offering full compatibility with consoles and the highest-quality gameplay. The television received the maximum rating in this category, providing everything one could desire. 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 TV to low latency mode, and VRR eliminates stuttering and screen tearing, resulting in fluidity and stability in gameplay. The Dolby Vision feature for gamers is another advantage, though it only works at 60 Hz. Most casual gamers are unlikely to feel the lack of a higher frequency, but more demanding users may have some reservations. This allows for enjoying a dynamic range of tones and realistic images, enhancing the gaming experience. PC gamers will also not be disappointed, as the Philips OLED769 offers full compatibility with Nvidia graphics cards, thanks to support for G-Sync. This technology synchronizes the TV's refresh rate with the graphics card, eliminating tearing and stuttering, translating to excellent image smoothness.

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

Let's move on to the features for gamers, although we must point out right away that this is more of a proposal for "casual" players. 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 gimmick. 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 most important advantage. That's a shame. (That’s why we mark it as HDMI 2.0 ports in our tests). Another oddity is the television's response to attempts to calibrate HDR from the console. Changes in brightness settings cause very unnatural behavior of the image, which might suggest an incorrect implementation of the HGiG standard. To be honest, however, you shouldn't worry too much about this, because as we have mentioned multiple times, we simply do not recommend using any HDR content on this screen. However, to make it not so bitter, 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. Although it works in a very modest range of 48-60 Hz, its very presence is commendable. Thanks to this, the image in games can stutter less, which truly improves the gaming experience.
