Samsung QN90F / QN92F vs Haier Q80FUX

The Samsung QN90F can truly shine with brightness. In our measurements, it achieved over 2200 nits, which directly translates to the viewing experience. In practice, this means that when a film features a very bright scene – for example, a sunrise in The Meg – the screen looks as if it is actually lit by natural light. This is not just a number from a chart, but a real sense of image intensity! However, the television may not always deliver this full power. With smaller details like reflections or lamps, brightness drops to 500–700 nits. This is a deliberate decision by the algorithms – it allows for better control of the contrast between large and small elements, preventing the image from losing balance. Importantly, this is still a huge improvement compared to last year's QN90D, where similar details were often almost invisible, shining at just 200 nits. Here, the HDR effect is much more consistent and credible. The only downside is the colours. The DCI-P3 coverage has stalled at 91%, which in this price bracket can be considered a rather average result.

Alright, let’s move on to the topic that stirs up so much discussion, namely the capabilities of the television in HDR mode. Let’s state it clearly right away: the Haier Q80FUX is certainly not a brightness demon. The panel of this receiver can generate about 350 nits at peak, which in today’s terms is the absolute minimum to even talk about the presence of High Dynamic Range (HDR). On the positive side, this power is at least stable – regardless of which test pattern or film scene we used, the measurements consistently oscillated in the range of 300-350 nits. These are therefore results that are at best sufficient, definitely far from the dazzling display of capabilities we are accustomed to with more expensive models. Fortunately, there is one aspect in which the Q80FUX compensates for these shortcomings and does so impressively. After all, we are talking about a QLED television (more precisely PFS LED), which means that thanks to the quantum dot filter applied to the panel, it can generate really juicy, vibrant colours. These are not empty promises – a DCI-P3 colour gamut coverage of nearly 95% is an impressive result and directly translates into colours that are very pleasant to the eye and saturated.

The colour reproduction of the QN90F was tested in Filmmaker mode and, as is often the case with Samsung televisions, this mode proves to be the best starting point straight out of the box. However, this does not mean that the image is free from flaws. The white balance in both SDR and HDR content was surprisingly good – the colours did not drift in any direction and even in its factory settings, it looked solid. A problem arose with the gamma curves and EOTF, which dictate how the television manages brightness. Here, the QN90F significantly brightened the entire image, causing blacks and colours to lose their intensity, and the overall effect resembled that of an applied milky filter. Fortunately, Samsung, unlike many competitors in the miniLED world, provides the user with plenty of tools to control the settings that we do not find with other manufacturers, such as Chinese producers. Therefore, we decided to see if we could squeeze the full potential out of the QN90F because we know that such a high-end series is capable of much more.

Factory settings for movie mode are rarely perfect, but in the case of the Q80FUX, we were confronted with a noticeable imbalance. In SDR content, the image was decidedly too warm, a result of excessive red in the white balance, giving the whole a slightly sepia tone. Ironically, in HDR materials, the television fell into the opposite extreme – an excess of blue caused an unnatural, cold effect in perception. However, it was not the capricious white balance that was the biggest problem with this television. The real culprit, responsible for the aforementioned issues, was hiding deeper. It turned out that the Q80FUX has completely miscalibrated gamma values and, crucial for HDR, a poorly executed EOTF curve. It was these erroneous factory settings that caused persistent clipping of the brightest parts of the image, overlaying them with that characteristic milky filter. Thus, we found the source of the problem. This state of affairs led to general, significant colour errors, which were easy to catch even for an untrained eye. Like every television we tested, we decided to calibrate this model as well, and the results of these adjustments can be found in the next paragraph.

After our adjustment of the settings, the QN90F displayed what it is truly capable of – and it must be admitted that this is one of the best images we have seen on a miniLED screen this year. As we mentioned earlier, the white balance was not a major issue even in its factory state, but only after gamma calibration did it manage to get close to reference values. The same is true for HDR content, where the EOTF curve post-adjustment presents mature and cohesive results. Indeed, in some films, it is noticeable that the smallest elements of the image are slightly brightened, and with a limited number of dimming zones, there is still a risk of halo effect. However, it should be remembered that such phenomena are characteristic of all miniLED televisions, and it is difficult to expect miracles even from the QN90F. The most important thing is that after calibration, the television delivers an image that, in terms of representing the director's vision, confidently competes with many OLED screens available on the market.

The results of our calibration procedures must, regrettably, be acknowledged as twofold. Generally speaking, the picture is undeniably better than before the corrections; however, the biggest winner of this process turned out to be SDR content. It is precisely there, after correcting the gamma and white balance graphs, that we achieved results that can confidently be called very good. After adjustment, the Q80FUX truly shines in standard dynamics, showing only slight errors in the most difficult skin tone reproductions. Unfortunately, the weakest link remains HDR content. Here lies the paradox: despite having calibrated the white balance to nearly perfection, the overall colour errors still remain at quite a high level. The reason is that the television continues to interpret static HDR10 metadata "in its own way," stubbornly enforcing that unfortunate image burn-out effect, which inevitably leads to significant distortions. Although we have successfully eliminated the factory excess of blue, it is precisely due to this interference of electronics that the screen still tends to stray into somewhat overly cold tones. That is just how this television is.

QN90F handles upscaling very well. Materials in lower resolutions, even SD, are enhanced to a clear and sharp image, in which a lot of detail in the background can be seen. This is a significant advantage, as the television makes older content or everyday television look considerably better than on most budget screens. However, the issue of overscan remains, which is the trimming of the screen edges, and this cannot be turned off in Samsung TVs. This can cause some subtitles on the screen to disappear or Auntie's face from the wedding on the VHS tape to be slightly cut off. 😉

Digital image processing also works well. In the menu, we find a function called "noise reduction," which can smooth tonal transitions and improve the reception of lower quality materials, e.g. from YouTube. At the medium setting, the effect is most beneficial – it does not heavily interfere with details, while eliminating the problem of "stepping" in colours. However, it is worth remembering that the function can be quite aggressive and removes natural grain from older films, so it is best to use it in moderation.

If there is one area where Haier clearly shows it still has a long way to go compared to the market leaders, it is digital image processing. The upscaling, well... is just alright. And that’s really about all that can be said about it. It does what is expected of it: it ensures that lower resolution signals do not scare us with harsh pixelation on the screen and do not look like a forcibly enlarged postage stamp. However, it is far from the finesse and “intelligent” sharpening that more experienced players in this market have developed over the years. The biggest shortcoming of the Q80FUX software is the almost complete lack of any additional "cleaning" and smoothing functions for the image. The receiver does not offer any noise reduction or gradient improvement mechanisms. This means that with older or heavily compressed materials, we simply have to come to terms with the fact that any imperfections in tonal transitions or blending of colours, which we mentioned earlier, will continually accompany us during the viewing.

The QN90F is equipped with a panel that has a maximum refresh rate of 165 Hz, and although this advantage will primarily be appreciated by PC gamers, it is still worth highlighting. In films or sports broadcasts, we are limited to the classic 120 Hz, but this is not a cause for concern. In practice, the additional motion smoother is of greater importance here. With the "Motion Clarity" setting, we can adjust the picture to our own preferences. The blur reduction option is responsible for fluidity and ghosting in sports. Meanwhile, the "judder reduction" function improves motion smoothness in productions shot at 24 frames, such as films and series. If we set it high, the film appears smoother and more fluid than it was actually shot. Lower values, on the other hand, preserve its cinematic "rawness" with a visible film frame.

The issue of motion fluidity and blurring is largely predetermined by the use of a 60-hertz panel, which naturally makes it difficult to recommend this receiver to enthusiasts of very dynamic content. Fortunately, in the Q80FUX, we find a few options (although, as we shall see shortly, in reality only one) that are supposed to improve the experience with older film productions. There is a "De-Judder" slider available, which actually controls the smoothness of the image and allows us to adjust it to our preferences: from raw, cinematic frame rates to a more theatrical, smoothed presentation. However, a true surprise awaits us just beside it in the menu. There is also a second slider, supposedly dedicated to removing blur – a feature we typically encounter in 120Hz panels to combat motion blur in sports. However, as we expected, recalling memories from the tests of the K85F model, this slider here is merely a façade. Its adjustment does absolutely nothing to the image and it simply appears to be an oversight by the product engineers who left a non-functional option in the software for this type of panel.

QN90F has almost everything to be the perfect television for gamers. There’s no need to remind anyone of features like four HDMI ports, VRR, ALLM, or refresh rates reaching even 165 Hz. The Game Motion Plus mode deserves great praise, as it is a unique motion smoother for games. Thanks to this, it adds a few “artificial” frames and makes the image generated from the console look smoother than it should. This is a very unique solution in the world of televisions – rival systems usually do not offer this – and that is why Samsung has had a strong selling point among gamers for years, even despite the lack of support for the still niche Dolby Vision in games.

[UPDATE] We have updated our tests of Samsung televisions from the 2025 lineup due to the release of software version 1131, which restored the crucial feature for gamers, HGiG.

So why do we say "almost" the perfect screen? Unfortunately, like in recent Samsung models, we noticed an issue with the lack of the HGiG feature. This solution allows the television to leave the control of tone mapping up to the console, so that games look exactly as intended by the creators. What's worse, this feature was previously present and disappeared after software updates. Instead of minor improvements, we got a step back. It’s a shame, because without this absence, the QN90F could truly be the ideal choice for gamers in the miniLED category.

Stepping into the realm of gaming, the Haier Q80FUX proves to be quite a decent companion for the "casual gamer". Onboard, we find highly desired features such as VRR (Variable Refresh Rate) and ALLM (Auto Low Latency Mode). However, the biggest surprise is something else altogether. Although we are not dealing with a 4K@120Hz panel here, the television is capable of accepting and displaying a 120Hz signal at a lower resolution (Full HD). This is a very useful feature that allows for a conscious switch of the console to a lower resolution mode in exchange for significantly higher smoothness, which is a compromise entirely acceptable in the gaming world.

We won’t particularly complain about the lack of extras like the "Game Bar", as it's merely a nice addition. The most concerning issues arise when we delve into the world of HDR in gaming. Due to the television constantly adapting the signal "in its own way", setting the brightness on the console according to the HGIG standard is nearly impossible to achieve as per instructions. Worse still, in the Dolby Vision mode for gaming, the input lag increases to around 50 ms, which is a value high enough to render this mode practically unusable. However, in general, we would not recommend gaming on this television in HDR mode, so these are not such grave shortcomings. What is most pleasing is the presence of 120Hz in Full HD, which makes the Q80FUX a rather nice television for the occasional gamer.
