Our verdict

Samsung S90F is an excellent representative of the premium mid-range in the world of OLED TVs. We have an organic matrix here that guarantees perfect contrast – and no matter how much LCD manufacturers try with local dimming in Mini LEDs, this black simply cannot be replicated. The S90F shows its class without any compromises. Compared to last year's model, we get a slightly brighter WOLED panel, which in favourable conditions can reach up to 1200 nits. This is a result that suffices for comfortable viewing of HDR materials in most scenes at reference quality – especially on streaming platforms such as Netflix. The picture quality here is very high, regardless of whether we are watching a movie, playing on a console, or streaming a sports broadcast. By the way – versatility is one of the biggest advantages of this model. With 144 Hz refresh rate, very low input lag, and a full package of gaming features (including functional HGiG and the unique Game Motion Plus motion smoother), it's hard to complain about anything here. The Tizen system performed really well on the S90F. It has its limitations – primarily the closed ecosystem and a smaller selection of apps than Google TV – but if you mainly use the most popular services, this shouldn't be an issue. A big plus is also the remote, which can operate most connected devices – even despite the lack of a numeric keypad. There are downsides too. The built-in media player has issues with some formats, and the anti-reflective coating typical of WOLEDs doesn’t handle strong light very well – reflections can be noticeable. We also do not have support for DTS and Dolby Vision, but this is a standard at Samsung that's been expected for years. So is the S90F with a WOLED panel the perfect TV? No – but it really is very close. It is one of the most polished and complete OLEDs in this price range, which can easily handle any content, from a series on Netflix, to console gaming, to a Sunday match.

The debut of the Haier brand in the European television market with the K85F model feels quite rushed, and after thorough testing – almost unfinished. Analyzing this product leads to a fundamental conclusion: its biggest problem is not the quality of the panel used. Considering the price segment, it is simply average, with typical VA technology advantages such as high contrast and equally typical disadvantages like poor viewing angles. What truly disqualifies this model as a home entertainment centre is the glaring lack of engineering and, above all, software refinement. The list of shortcomings is long and starts with the first contact with the device. Shoddy assembly, which could have been avoided at the quality control stage, a terribly optimised and poorly translated Google TV system, or annoying issues with basic functions like pairing the remote – all contribute to an impression of a product that seems to have been launched without due diligence. Catastrophic picture quality in HDR mode, resulting not only from low brightness but also from a complete lack of smart adaptation to the signal, only adds to this disappointing picture. However, it turns out that this model has a surprising second face. Just looking at it not through the lens of a home television, but rather as a large and inexpensive display for special tasks, shifts its shortcomings to the background, bringing unexpected strengths to the forefront: a fantastically functioning media player with USB, excellent font readability from a PC, and access to a vast array of applications. In such a role – as a screen in a conference room, hotel lobby or a simple advertising player – the Haier K85F performs surprisingly well. For a typical user searching for a reliable and simply well-functioning television for the living room in 2025, however, the Haier K85F is a proposition that is extremely hard to recommend with a clear conscience. It is a product full of contradictions, which fails in too many areas in its primary, intended function as designed by the manufacturer.

Halo effect and black detail visibility:

Check the visibility of bright lights on a dark background. Mini-LEDs often struggle with this. The photo does not compare black levels – that’s what the video below is for.

The video accurately shows differences in contrast and black levels between TVs, as well as potential issues: halo around bright objects or Mini-LED zone operation visible as brightness jumps.

In the case of the Samsung S90F, we are dealing with an interesting situation: nearly all size variants have been equipped with WOLED panels, except for the 65-inch version, which received a QD-OLED panel. In this test, we analyse the version with the WOLED panel produced by LG Display, but the question remains; Does this affect the quality of black and contrast in this part of the test? In practice – it does not. Regardless of the technology used, both panels can produce perfect black and infinite contrast. This is exactly what we expect from any top-tier television. Watching a series in the evening, in a completely dark room, is sheer pleasure. The television easily separates bright elements – such as reflections or background lights – from the deep, dark parts of the image, without creating any halo or brightness issues that high-end LCD televisions still struggle with. This is where OLED technology shows its strength – and the S90F is no exception. When it comes to black and contrast, we can't fault it at all.

Alright, but let's get to the meat of it, that is, how the Haier K85F handles black and contrast. The key information is that the television uses a VA panel, which is crucial for image quality in dark scenes. Thanks to this, the contrast is really solid – our measurements indicated values around 5000:1, which is much better than popular IPS panels.

However, it is important to remember that we're discussing budget equipment. So, we shouldn't expect any advanced technologies like local dimming. The backlighting operates across the entire screen surface at all times. How did it look during viewing? We took the film "Oblivion" with its cosmic landscapes for a test, and we also checked classic black bars in other productions. The effect was quite decent. The black had good depth, but it wasn't perfectly inky – a slight blue glow could be noticed, indicating that the panel's backlighting was still active.

Luminance of RGB colors

Does the S90F handle not only blacks but also bright parts of the image? Definitely. The stories about OLEDs as "dark screens" can slowly be regarded as myth. The Samsung S90F, like the LG C5 based on a very similar panel, achieves brightness exceeding 1000 nits. This is a value more than enough to enjoy impressive and dynamic HDR images – both in movies and series. Most of the scenes we tested look stunning, with well-defined highlights and high contrast. Of course, OLED technology still has its limitations – in very bright, full-screen sequences, such as the test card from the movie The Meg (photo 5), the television may noticeably dim the image. However, it should be emphasized that such scenes are rare. It can be said that the HDR effect is good enough that even mid-range OLED models like the S90F can provide a cinematic experience in the home living room.

Let’s now move on to one of the hottest topics in the world of televisions, which is the quality of HDR performance. In the case of the Haier K85F model, we unfortunately have to make it clear: if you’re 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 that means – this level is fine for watching standard SDR content, but it’s absolutely insufficient to show any real benefits of HDR. The image simply doesn’t have the "power" to generate bright, striking highlights. All of our measurements and tests on specialised test patterns confirmed this. As if that wasn’t enough, the television also struggles with colour reproduction. In this budget build, there are no technologies that broaden the colour gamut, such as quantum dot layers (marketed as "QLED"). As a result, the coverage of the DCI-P3 colour space, which is crucial for HDR content, 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.

After calibration

Samsung S90F, like most modern televisions, offers many picture modes, but – following our testing tradition – we checked it out in the best one, which is the Filmmaker mode. Thanks to this, the image looks much more natural than in the default, often oversaturated settings. It was neither overly saturated nor artificially dimmed – simply closer to what one should see. Of course, “more accurate” doesn’t mean “perfect”. Unfortunately, our S90F had significant issues with white balance, particularly in the blue color range, resulting in a slightly yellowish filter being applied to most scenes. Someone might say it looks more “filmic” – because it’s warmer – but let’s not kid ourselves, George Lucas didn’t film Star Wars in sepia 😉 (you’ll find a comparison with the scene below as always).

Additionally, in HDR materials, there was an issue with brightness management. The EOTF curve showed a clear “spike” in brightness – the television brightened the image more than it should have, causing some effects to look too intense and deviating from the reference. Fortunately, some of these problems can be eliminated through professional calibration – you’ll read about its effects later in the review.

Alright, how does the television handle colours straight out of the box, without any intervention from our side? The Haier K85F offers a whole range of picture modes, such as Dynamic or Eco, but for anyone wanting to watch films according to the creators' intentions, there's essentially only one that matters: Film mode. This is where we focused our tests, and unfortunately, its name has little to do with reality. The picture on factory settings is very far from what we could call cinematic fidelity and requires many adjustments. Let's start with the white balance, which has a clear deficiency of red colour. In practice, this means the entire image has a cool, bluish tint. Even worse is the issue of brightness management, that is, the gamma curves (for SDR) and EOTF (for HDR). Their graph resembles a true rollercoaster, which terribly impacts the viewing experience. This results in unnatural dimming of SDR content, causing details in the shadows to be lost, and in the case of HDR – an excessive brightening that further exacerbates the problem of clipping. Such a combination, which consists of too cool white combined with chaotic brightness and too much blue colour saturation, leads to enormous errors in colour reproduction. Our measurements on a specialist ColourChecker chart showed errors (Delta E) regularly reaching and exceeding values of 8-9. To put it simply: errors above the threshold of 3 are easily noticeable to the naked eye, so such a result means that the colours on the screen are simply heavily distorted.

After calibration, we managed to eliminate practically all the previously mentioned errors. Older movies in SDR quality finally look like they should – without the sepia effect or artificial aging of the image. The atmosphere of the classics is back in place (no thanks needed, Star Wars fans), and the colours no longer resemble an Instagram filter.

One of the key changes was also the improvement of brightness characteristics in HDR content. We managed to control the EOTF curve in almost a reference manner. Admittedly, the most demanding users may detect minimal deviations in brightness, but honestly – most viewers won't even notice that. And it's no surprise because the vast majority of errors fall below the ΔE 3 value, which is below the threshold of visibility. After calibration, the S90F (WOLED) becomes a truly excellent display – one on which you can enjoy nearly perfect image quality.

No good, but can anything be done about this picture? Is professional calibration able to save the situation? The answer is both yes and no. It needs to be said clearly that there are certain things we cannot overcome. The limitations of the construction itself, namely a poor panel and its narrow colour coverage, mean that you can forget about a sensible HDR effect – we won't be pulling the wool over your eyes on that. The biggest beneficiary of our adjustments is undoubtedly the SDR mode, and it is for watching such content, after calibration, that this television starts to make sense. We managed to tame the white balance in our own way. Although the television only offers basic, 2-point adjustment (rather than precise, 20-point), it's not perfect, but we successfully eliminated that unpleasant, cold "chill" in the picture. Above all, though, we noted a huge 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 an image without artificially dimming or brightening it. The conclusion is simple: even with such a cheap television, professional setting correction can achieve a great deal and extract the maximum potential from it.

No and here we must honestly admit – the S90F has somewhat let us down. Compared to last year's S90D model with a WOLED panel (very similar to the one used this year), this year's Samsung performed worse. And this is not only against its main competitor, LG C5, but even when compared to its older brother. The biggest issues arise in dark scenes, where difficulties with smooth colour transitions are noticeable – the screen slightly steps the tonal transitions, causing some sections to lose their naturalness. We’re not sure what exactly went wrong – perhaps it's a software issue or a different processing algorithm. It's a shame, because we hoped that the level from last year would at least be maintained. Unfortunately, it's a step backwards.

It's time to address an issue that is often overlooked by many but can be quite irritating to the discerning (and not just discerning) eye. We're talking about the smoothness of tonal transitions, or how seamlessly the screen displays transitions between very similar shades of one colour – for instance, on a clear blue sky. We have to admit that in this category, the Haier K85F, considering its price, performs quite decently. In bright scenes, such as the aforementioned sky or expansive landscapes in the film "The Martian," there are no stark, contrasting bands. Yes, if we scrutinise closely, we can spot minimal imperfections, but generally, the effect is more than satisfactory. However, the situation changes when darker scenes make an appearance on the screen, such as gloomy corridors in games or nighttime landscapes. Here, banding, or the effect of posterization, becomes much more evident. Transitions in shadows and greys are no longer as smooth and can become quite bothersome to a more sensitive eye. It's not a level that would completely disqualify the television, but it is clear that this is an area where costs were saved.

Digital Image Processing in S90F:

Fortunately, Samsung, like in most of its models, manages to effectively tackle the unwanted posterisation effect in the S90F. The function responsible for this element is noise reduction, which does a pretty good job of smoothing tonal transitions and eliminating unnatural colour blending – of course, within its capabilities. Unfortunately, it works quite aggressively, so using it comes with trade-offs. In addition to improving gradation, it can also remove film grain or slightly soften facial features. In this case, the choice is yours – do you prefer a more "clean" image, or do you care about preserving the original texture of the material.

Image Scaling in S90F:

In this year's model, Samsung has implemented its proprietary AI processor – NQ4 Gen3, which really handles upscaling quite well. In our test scenes, the TV effectively "pulled up" lower quality towards artificial 4K – the image was more enjoyable to view, and the differences in sharpness between native and scaled content were minimal. Unfortunately, behind all this AI marketing façade lies a certain shortcoming. The S90F struggles with overscan. If you reach for truly archival material – e.g. a VHS tape of your parents' wedding – you have to reckon with the fact that the lower part of the image may get cut off. The function to adapt the image to resolution simply does not work as it should here.

Let’s move on to digital processing and image scaling, specifically how the Haier K85F handles lower resolution signals, such as from regular television. Right off the bat, we encounter an incredibly annoying and completely incomprehensible issue – the overscan is enabled by default. This means the television artificially enlarges the image, cutting off its edges on every source, even 1080p. To see the full frame, you have to dig into the screen settings each time and manually switch the format to "stretch to 16:9." It's a minor detail, but devilishly frustrating. The scaling of content to 4K resolution can be described in one word: acceptable. And that's about it. The image processor doesn't strip detail from the image, nor does it generate jagged edges or other artifacts. It simply does its job, without any bells and whistles. It’s alright, but nothing more. The most significant and noticeable shortcoming in the digital processing section is, however, the absence of a tone transition smoothing feature. This is an algorithm that could significantly reduce the annoying banding effect we mentioned earlier. Unfortunately, the manufacturer did not foresee such a solution, condemning us to watch the imperfections of the panel and low-quality material in all their glory.

Blur (native resolution, maximum refresh rate):

S90F really handles motion excellently – after all, it’s an OLED with a 144 Hz panel, so sports and games look absolutely stunning on it. The image is smooth, clear, and there’s no room for ghosting or blurring, which can sometimes plague cheaper LCDs.

The TV also comes equipped with motion smoothness settings that allow you to customise everything to your liking. We have motion blur reduction and judder reduction – you can set it so that the image is super smooth (even to the point of looking a bit soap opera-like), or more cinematic, with the classic “jumpiness” of 24 frames. The choice is yours, Samsung imposes nothing.

The panel in the K85F model operates at a native refresh rate of 60 Hz, which sets certain expectations for image smoothness right from the start. However, we must admit that we were very positively surprised when we found two separate motion control sliders in the settings menu: one labelled "Motion Blur Reduction" and the other "De-Judder." Such generosity in this price segment is an absolute rarity, as manufacturers usually offer at most one shared option. Unfortunately, our enthusiasm faded as quickly as it appeared. It soon became clear why Haier was so "generous" – the slider responsible for reducing motion blur is simply a decoy. Sliding it makes absolutely no visible difference on the screen, so only one of the two options works.

When it comes to gaming features – the S90F has absolutely nothing to complain about. Aside from the lack of Dolby Vision, which is already the norm for Samsung. The television operates at 144 Hz, has four HDMI 2.1 ports, so you can easily connect more than one console or PC. Onboard, we also find Game Bar – a practical tool that allows you to quickly preview picture settings, VRR status, ALLM mode, and other useful options. Game Motion Plus deserves special mention – Samsung's proprietary motion smoother that actually works sensibly in games. The image appears smoother, but without any artificial effects or slowdowns.

It's also worth mentioning the HGiG feature, which – and this may be a slight surprise – works correctly. We bring this up because Samsung clearly messed something up in one of the recent updates, and in some models, the option responsible for HGiG simply... disappears from the menu. Setting it up becomes almost impossible. Fortunately, our S90F unit did not have this issue, but the situation is dynamic, so it's worth keeping this in mind and regularly checking for new software versions and information from the manufacturer.

Let’s move on to the features for gamers, although we must point out straight away that this is more of a proposal for the "occasional" ones. The manufacturer does boast in the specifications about having HDMI 2.1 ports, which looks impressive on paper, but in reality, it’s largely a marketing ploy. 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 key advantage. What a shame. (That’s why in our tests we note this as HDMI 2.0 ports). Another odd issue is the TV's response to an attempt to calibrate HDR from the console. Changes to brightness settings result in very unnatural image behaviour, which could suggest incorrect implementation of the HGiG standard. To be honest, one shouldn’t worry too much about this, as we have repeatedly mentioned, we simply do not recommend using any HDR content on this screen. However, to counterbalance the negatives, the Haier K85F does have two big and unexpected advantages. The first is the presence of ALLM, or automatic game mode, which switches the TV 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 operates within a very modest range of 48-60 Hz, its mere presence is commendable. Thanks to this, the image in games can “tear” less, which realistically improves the gaming experience.

Input lag in the S90F is at a level that's practically monitor-like. Under the best conditions, it achieved a score of 5 ms, which is an absolutely stunning result – even a benchmark for the most demanding gamers. Whether you're playing fast-paced shooters, fighting games, or simply need instant response – the S90F does not disappoint in this regard at all.

We must give credit where it's due – there is one parameter where this television absolutely shines and puts to shame many more expensive models. We're talking about input lag, or signal delay. Our measurements showed a remarkably low result of just 13 ms. This is a huge plus that makes gaming control lightning-fast and incredibly responsive. In this regard, the K85F performs excellently.

The photo shows the legibility of small fonts. Ideally, lines should be the same thickness on both light and dark text, with minimal pixel gaps.

S90F is a great tool for both gaming on PC and daily work. Gamers can rest easy – the TV effortlessly supports image synchronisation with NVIDIA graphics cards thanks to G-Sync, and the 144 Hz refresh rate combined with very low input lag only confirms this. S90F also excels as a monitor for working with text. Of course, the readability of fonts may be slightly compromised by the characteristic pixel structure in the RWGB arrangement, but this is a topic well known primarily to those who work with a lot of text, code, or Excel spreadsheets. For most users, this will be perfectly acceptable.

And what if we tried using this Haier as a computer monitor? Here, what was a big surprise for us was that the television performs exceptionally well. For office work, it’s perfect. All thanks to the fact that it correctly handles the so-called 4:4:4 chroma sampling. To put it simply: every little letter on the screen is sharp, without annoying coloured edges or blurriness. Sure, let’s be frank – this is not equipment for PC gamers. 60 Hz is too low for them. But if you just need a big screen for text work, browsing the internet, coding or displaying presentations, the K85F excels in this role. This is one of its strongest and, let’s face it, most unexpected applications.

The viewing angles on the S90F are very good, although it must be honestly admitted that they are slightly inferior to the 65" version with the QD-OLED panel. Nevertheless, the picture quality at wide angles performs very well – colours remain vivid, and brightness doesn’t drop dramatically when viewed from the side. There's no need to move the TV closer to see a clear image. For most users, this level is more than sufficient.

At nearly the very end of the evaluation of the panel itself, we left out the viewing angles, which unfortunately are one of its biggest weaknesses. It must be honestly admitted that this is not surprising – it is simply a natural and commonly known feature of VA-type panels. In the unit we tested, interestingly, the brightness of the image did not drop drastically when we moved away from the centre of the screen. However, the real problem lies with the colours, which instantly begin to fade. A slight change in position on the couch is enough for the hues to lose their saturation and become washed out. In this regard, the Haier K85F presents a very average, typical level for this technology.

Haier K85F: 276 cd/m2

SAMSUNG S90F (WOLED): 405 cd/m2

S90F is really bright for an OLED TV. Of course, it shouldn’t be compared to Mini-LED TVs or the brightest high-end OLEDs, but under normal lighting conditions, it’s easy to watch something during the day. The brightness is high enough that there’s no need to close the curtains every time a movie or series is turned on. However, it’s important to remember that the anti-reflective coating on WOLED panels is not the best. Reflections can be noticeable, especially with bright light coming in from the window. In such cases, it’s best to reach for curtains.

And how does the television perform in confrontation with daylight, for example in a brightly lit living room? Unfortunately, we don't have good news here. As we have established, it is a television with relatively low brightness, which becomes a serious drawback when faced with sunlight. The situation is further worsened by the screen coating used. Instead of effectively suppressing reflections, its satin structure tends to unfavourably scatter them. In practice, this means that the reflection of a window or lamp turns into a large, blurred, milky haze that degrades contrast and effectively hinders viewing. The conclusion is therefore clear: if the television is to be placed in a bright room, the K85F model will not be a good choice.

Review Haier K85F TV features

Samsung S90F is equipped with a range of classic TV features, such as EPG, CI module, and headphone support, but there’s also more to it. Thanks to the presence of several tuners, the TV offers a picture-in-picture (PiP) function – very useful, for example, when we are watching one match but want to check the score of another match happening simultaneously. It's a pity that Samsung has completely abandoned the USB recording feature for some time now, but this is partially compensated by good integration with decoders and other devices. The remote – while small and lacking a numeric keypad – allows you to control multiple devices connected to the TV. You can easily manage a decoder, amplifier, console, or other gear with it – all without needing to reach for several remotes.

As for the Smart TV system – Tizen on the S90F operates very smoothly, which is not a given in cheaper models with this system. The system itself is extensive and offers plenty of features – we have screen mirroring, AirPlay, Bluetooth device support, and quite a few options related to smart home functionality, such as controlling bulbs or other smart devices directly from the TV. However, it’s important to remember that Tizen is a closed system, so when it comes to apps – we are limited to what we find in the Samsung store. And while it is quite extensive, it doesn’t match the flexibility of the Google TV platform. It’s worth keeping this in mind if you have specific needs for niche applications.

GoogleTV on Haier K85F

The heart of the television is the Google TV system, which in theory should be a huge advantage. Access to thousands of apps and a wealth of features are promises we are familiar with. Unfortunately, in Haier's execution, this is one of the worst implementations of this software we have encountered. The system operates painfully slowly, and the interface notoriously freezes. However, the real nightmare is the incorrect and often downright comical translations of some menu options, making it difficult to figure out what is being referred to at times. To make matters worse, during our testing, we couldn't get the AirPlay feature to work at all.

Classic Features on Haier K85F

Let's move on to the classic functions and ports, because the story here is even more interesting. A plus is definitely the rich array of ports, including four HDMI connections and the increasingly rare mini-jack headphone output. Unfortunately, the television does not offer either USB recording or Picture-in-Picture mode. However, the real ordeal begins with the remote. Our initial attempts to pair it via Bluetooth to activate radio (RF) control and voice functions ended in total failure. After dozens of attempts, we were convinced it was simply a manufacturing defect. And then the surprise: after a long struggle, we discovered that the remote can be paired, but it must be done from the native Google TV settings, completely bypassing Haier's dysfunctional system overlay. This is a perfect example of how terrible software can ruin basic functionality. Oh, and one more thing. In the box... there weren't even batteries for the remote.

The built-in media player in the S90F is alright and supports quite a few popular formats. Unfortunately, during testing – once again – we encountered issues, despite the manufacturer's claims. The television did not play some formats that are supposedly supported, such as HEIC photos (Apple's version), or SRT and SUB subtitle files. In everyday use for most people, such a player will be sufficient to play a movie from a USB drive, but it’s worth keeping in mind that surprises may occur. Perhaps the situation will be improved in future updates, but at the time of writing this review – it works as it works.

After all our complaints about the unfinished software, the moment came when we were absolutely shocked. It turns out that within this buggy and slow-running system, there is a function that works almost perfectly and puts industry veterans to shame. We are talking about the built-in media player for USB drives. It is a true multimedia powerhouse that played practically every video format we threw at it without the slightest hiccup – from the most popular to the completely niche. Haier, a newcomer to the TV market, has achieved something that many manufacturers with decades of experience have struggled with for years. Who knows, perhaps it was originally intended as a reliable player for conference rooms? Regardless of its origins, the result is outstanding!

The S90F plays really quite nicely, with noticeable bass and pretty good dynamics. A definite plus is the support for Dolby Atmos, which allows the TV to sound a bit more “spatial” – of course, as much as the built-in 2.1 set allows 😉. Unfortunately, as is often the case with Samsung, it lacks support for the DTS:X format. So, if you want to take advantage of its capabilities, you'll need to connect your audio equipment directly to the amplifier, rather than to the TV itself – otherwise, it just won't work.

When it comes to sound, the review will unfortunately be very short. The biggest advantage of the built-in speakers of the K85F is that they simply exist and produce sound. Other than that, the sound is completely flat, lacking any bass and just anemic. Yes, on the TV's box we will find the Dolby Atmos logo, but against the physical capabilities of these drivers, it is a feature that exists only on paper. Therefore, the verdict can only be one: when planning to purchase this TV, a soundbar should immediately be added to the budget.
