Samsung QN990F vs Haier Q80FUX

The Samsung QN990F belongs to the bright televisions category, and this is immediately evident in tests. In measurements, it achieved around 1300 nits, which in practice allows for enjoying films as their creators intended. Bright scenes have the right intensity, lights shine, and the experience is truly cinematic. In standard test patterns, sequences number 1, 3, and 5 performed best – there, brightness maintained around 800-1000 nits, and the image looked very natural. In more challenging segments, it could drop to around 600 nits, but even so, the level remained sufficient for details to be clearly visible. However, it should be added that in highly contrasting shots, the halo effect returns – the same one we mentioned regarding black levels. Bright elements can leave a halo on dark backgrounds, and this stands out immediately. Since we are dealing with a QLED, the colour palette is expanded, and the colours appear striking. The problem is that with such a flagship model, we expected better numbers. 91% DCI-P3 coverage and about 67% BT.2020 are results that can be considered solid, but not outstanding. This gives a vibrant and appealing image, yet the competition in this and lower price tiers can showcase even more.

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.

We tested the QN990F in Filmmaker mode, which is the best available right out of the box. Right from the start, we noticed several significant errors. The biggest issue concerned white balance. Due to too little blue, and also improper ratios between red and blue, the image – especially in scenes with a lot of white – appeared too yellow, and at times even orange. On the Color Checker palette, these errors didn't look dramatic as they hovered around a value of 4, but in everyday viewing, especially with strong whites, they were most noticeable. We also observed issues with brightness management – the television struggled to maintain detail in the smallest parts of the image, mainly due to the way it controls the backlighting zones. Fortunately, Samsung offers a lot of room for adjustment when it comes to calibration settings. We know that with the right calibration, much more can be extracted from this screen.

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 completing the calibration, we managed to bring the white balance back to order and eliminate the previous shortcomings in the shades of blue. As a result, the image no longer looked as if it had a slightly yellowish filter applied – the whites are purer, and the overall presentation is much more natural. We also managed, to some extent, to tame the brightness characteristics in HDR content. The television now handles detail retention in blacks significantly better and does not lose them to the same degree as before. However, when we look at the EOTF curve and the way the QN990F reproduces brightness in films, it is evident that it still tends to accentuate details in dark areas more strongly. This is a characteristic feature of Mini-LED technology and, more specifically, the way it is managed by the QN990F, which is practically impossible to completely eliminate. Despite this, after calibration, the image appears much more natural, mainly due to the correct exposure of white light. The final effect is definitely more pleasant to perceive and closer to what we expect from a flagship television.

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.

The biggest praise for the QN990F should be given for its upscaling. The processor responsible for "lifting" classic television to 8K resolution does quite well. While watching material in 576p signal, we had no illusions that we would suddenly see a miracle in advertising style, where the image magically transforms into crystal-clear 8K. Nevertheless, the end result was surprisingly good; the image looked clean and sharp. It’s just a shame that the television, like most Samsung models, has an overscan issue, slightly cropping the edges of the screen from the left side.

When it comes to image processing, Samsung offers a feature called "noise reduction," which in theory should improve tonal transitions in older materials, where they are usually more visible. Unfortunately, we felt quite disappointed here. The feature performs poorly – it does not handle unwanted stripes and can introduce its own artifacts. On the plus side, the television does not remove film grain when using this feature, but in practice, that is a poor consolation since the noise reduction itself proves to be virtually useless.

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.

QN990F can comfortably be called one of the fastest televisions in the world. In 4K mode, it is capable of displaying images at a frequency of up to 240 Hz, which until now has been more associated with gaming monitors than with televisions in the living room. However, in everyday viewing, what matters more is how it handles the 8K signal at 120 Hz – and here it performs very well too. Motion remains smooth, and the television manages without a hitch even with the most demanding content. Additionally, there is the motion smoother, i.e. "Picture Clarity". Thanks to it, one can adjust the image to their own preferences – leaving a slightly cinematic judder or switching to maximum fluidity, which works exceptionally well, for example, in sports broadcasts.

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.

It must be said outright – the QN990F is one of those televisions that practically scream that they were designed with gamers in mind. Samsung has been developing its gaming solutions for years, but here we have a truly comprehensive set. Sure, it lacks Dolby Vision support in games, which is a downside that will always come up in discussions. However, aside from that, the list of features is impressively extensive. To begin with, we have the Game Bar – a handy menu that allows you to quickly check and change gaming-related settings. You can see, for example, the enabled VRR, frame rate, or aspect ratio settings. It’s like a little “dashboard,” making it unnecessary to dig deep into the menu to make adjustments. Speaking of VRR: yes, variable refresh rate is present here and works flawlessly. And there's ALLM, which automatically switches the television to game mode as soon as the console is powered on. These may seem like small details, but together they make using the QN990F simply comfortable and hassle-free.

However, the most impressive aspect is the number of ports. Four wireless HDMI 2.1 ports are already great news, as there is no need to choose whether to connect the console, the amplifier, or perhaps even a PC. There’s ample space for everything here. And if we add another micro HDMI (which we recommend connecting directly to the console), hidden in the casing, we practically have five inputs in full 2.1 standard. Let’s also add support for high refresh rates – 120 Hz at 8K and even 240 Hz at 4K – and we get a television that not only keeps up with the new consoles but also feels ready for consoles that are not yet available.

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.
