Samsung QN990F vs Haier Q80FUX

The Samsung QN990F belongs to the bright televisions and this is immediately evident in the tests. In measurements, it achieved around 1300 nits, which in practice allows you to enjoy movies as their creators intended. Bright scenes have the right impact, lights shine, and the feeling is truly cinematic. In standard test patterns, sequences number 1, 3, and 5 performed the best – there the brightness remained around 800-1000 nits, and the image looked very natural. In more challenging segments, it could drop to about 600 nits, but still the level remained sufficient for details to be well visible. However, it should be added that with such highly contrasted shots, the halo effect returns – the same one we mentioned regarding the blacks. Bright elements can leave a glow on dark backgrounds, and this is immediately noticeable. Since we are dealing with a QLED, the color palette is expanded and the colors look impressive. The problem is that with such a flagship model, we expected better numbers. 91% coverage of DCI-P3 and about 67% BT.2020 are results that can be considered solid, but not outstanding. This results in a vibrant and attractive picture; however, competition in this and lower price segments can show even more.

Alright, let's move on to the topic that generates so much discussion, namely the capabilities of the TV in HDR mode. Let's make it clear 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 reality is an absolute minimum to even talk about the presence of extended HDR tonal dynamic range. On the plus side, this power is at least stable – regardless of the test pattern or movie scene we used, the measurements invariably oscillated around 300-350 nits. These are therefore at best adequate results, definitely far from the stunning showcase of capabilities that we know from more expensive models. Fortunately, there is one aspect in which the Q80FUX makes up for these shortcomings and does so abundantly. After all, we are talking about a QLED TV (or more precisely, PFS LED), which means that thanks to the quantum dot filter applied to the matrix, it can generate really juicy, vibrant colors. These are not empty promises – a DCI-P3 color gamut coverage reaching nearly 95% is an impressive result that directly translates into very pleasant, saturated colors for the eye.

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 was with white balance. Due to too little blue and also incorrect proportions 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 noticed issues with brightness management – the television had difficulty maintaining details in the smallest parts of the image, mainly due to the way it controls the backlight zones. Fortunately, Samsung offers a lot of room for adjustment when it comes to setting corrections. We know that with proper calibration, you can definitely get a lot more out of this screen.

Factory settings for film mode are rarely perfect, but in the case of the Q80FUX, we encountered a noticeable imbalance. In SDR content, the image was definitely too warm, which resulted from an excessive amount of red in the white balance, giving it a slightly sepia tone. Contrarily, in HDR materials, the television fell into the other extreme—the excess of blue created an unnatural, cold effect. However, it wasn’t the whimsical white balance that was the biggest problem with this TV. The real culprit, responsible for the previously described issues, was hidden deeper. It turned out that the Q80FUX had completely misaligned gamma values and, crucially for HDR, a poorly managed EOTF curve. It was these erroneous factory settings that caused notorious clipping of the brightest parts of the image, applying that characteristic milky filter over them. Thus, we found the source of the problem. This state of affairs led to overall, significant color errors that were easy to catch even for an untrained eye. Like every television we tested, we decided to calibrate this model as well, and you can find the results of those adjustments in the next paragraph.

After performing calibration, we managed to bring the white balance into order and eliminate the previous deficiencies in blue tones. As a result, the image no longer appeared as if it had a slightly yellowish filter – whites are cleaner, and the overall presentation looks much more natural. We also managed to some extent to tame the brightness characteristic in HDR content. The television now handles maintaining details in blacks significantly better and does not lose them as much as before. However, when we look at the EOTF curve and how the QN990F reproduces brightness in films, it is evident that it still tends to emphasize details in dark scenes more strongly. This is a characteristic feature of Mini-LED technology, and more specifically, how it is managed by the QN990F, which is practically impossible to completely eliminate. Nevertheless, after calibration, the image looks much more natural, primarily due to the correct exposure of white light. The final effect is definitely more pleasant to receive and closer to what we expect from a flagship television.

The results of our calibration efforts must, unfortunately, be considered twofold. Overall, the image is indisputably better than before the corrections, but the biggest winner of this process turned out to be SDR content. It is here, after clarifying the gamma and white balance graphs, that we obtained results that can confidently be called very good. After the setup, the Q80FUX truly shines in standard dynamics, showing only slight errors in the most challenging skin tone reproductions. Unfortunately, the weakest link still remains HDR content. And here lies the paradox: even though we managed to calibrate the white balance almost to perfection, the overall color errors still remain at a fairly high level. The reason is that the television still interprets the static HDR10 metadata "in its own way," stubbornly enforcing that unfortunate washed-out image effect, which inevitably leads to significant distortions. Although we successfully eliminated the factory excess of blue color, due to this electronic interference, the screen can still tend to fall into somewhat too cold tones. This television just has it this way.

The QN990F deserves the highest praise for its upscaling. The processor responsible for "pulling up" classic TV to 8K resolution performs quite well. While watching content in a 576p signal, we had no illusions that we would suddenly see a marketing-style miracle where the image magically transforms into crystal-clear 8K. Nevertheless, the final effect was surprisingly good; the image looked clean and clear. It's just unfortunate that the TV, like most Samsung models, has an overscan issue, which slightly cuts off the edges of the screen on the left side.

Regarding image processing, Samsung provides a feature called "noise reduction," which in theory should improve tonal transitions in older materials, where they are usually more noticeable. Unfortunately, we felt quite disappointed here. The feature works poorly – it struggles with unwanted bands and can even introduce its own artifacts. On the plus side, the TV does not eliminate film grain when using this feature, but in practice, that's little consolation since the noise reduction itself proves to be practically useless.

If there is one area where Haier clearly shows that it has quite a bit to catch up on compared to the market leaders, it is digital image processing. The upscaling, well... is just okay. And that's about all that can be said about it. It does what it is supposed to do: it ensures that lower resolution signals don't scare you with harsh pixelation on the screen and don't look like an overly 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 drawback of the Q80FUX software, however, is the almost complete lack of additional "cleaning" and smoothing functions for the image. The receiver does not offer any noise reduction or gradient enhancement mechanisms. This means that with older or more heavily compressed materials, we simply have to accept that any imperfections in tonal transitions or color blending, which we mentioned earlier, will constantly accompany us during the viewing.

The QN990F can easily be called one of the fastest televisions in the world. In 4K mode, it can display 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 8K signals at 120 Hz – and it performs very well here too. Motion remains smooth, and the television manages without a hitch even with the most demanding content. Additionally, there is a motion smoother, called "Picture Clarity." With it, you can adjust the image to your own preferences – leave a slight cinematic stutter or switch to maximum smoothness, which works great, for instance, in sports broadcasts.

The issue of motion fluidity and blurring is largely predetermined by the use of a 60Hz 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 (though, as we will see shortly, actually only one) designed to improve the experience with older film productions. There is a "De-Judder" slider available, which indeed affects 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 genuine surprise awaits us right next to it in the menu. There is also a second slider, supposedly dedicated to eliminating blur – this is a feature we usually encounter in 120Hz panels, aimed at combating motion blur in sports. However, as expected, recalling memories from testing the K85F model, here too this slider is merely a facade. Moving it does absolutely nothing to the image and it simply looks like an oversight by the product engineers who left a non-functional option in the software for this type of panel.

It must be said directly – the QN990F is one of those TVs that screams it was designed with gamers in mind. Samsung has been developing its gaming solutions for years, but here we have a true package. Sure, the lack of Dolby Vision support in games is a downside that will always come up in discussions. However, apart from that, the list of features is truly impressive. To start, we have Game Bar – a handy menu that allows you to quickly check and change game-related settings. You can see, for example, VRR is turned on, the frame rate, or the aspect ratio settings. It's like a small "dashboard," allowing you not to dig deep into the menu to make adjustments. Speaking of VRR: yes, variable refresh rate is present here and works flawlessly. Additionally, there's ALLM, which automatically switches the TV to game mode as soon as the console is turned on. These may seem like small details, but together they make using the QN990F simply convenient and hassle-free.

However, the number of ports makes the biggest impression. Four wireless HDMI 2.1 ports are already great news because you don't have to choose whether to connect the console, the receiver, or maybe even the PC. There's plenty of room here for everything. And if we add an additional micro HDMI (which we recommend connecting directly to consoles), hidden in the housing, we practically have five inputs in full 2.1 standard. Add to that support for high refresh rates – 120 Hz in 8K or even 240 Hz in 4K – and we get a TV that not only keeps up with the new consoles but also feels ready for consoles that are yet to come.

Stepping into the gaming territory, the Haier Q80FUX proves to be quite a decent companion for the "casual gamer." On board, we find today’s highly desired features like VRR (variable refresh rate) and ALLM (automatic low latency mode). However, the biggest surprise is something else. Although we are not dealing with a 4K@120Hz panel, the TV can accept and display a 120Hz signal at a lower resolution (Full HD). This is a very useful feature, allowing the conscious switch of the console to a lower resolution mode in exchange for significantly higher fluidity, which is a perfectly acceptable compromise in the gaming world.

We won’t particularly complain about the lack of extras like the "Game Bar," as it’s just a nice addition. The most concerning issues arise when we enter the world of HDR in games. Due to the fact that the TV constantly adapts the signal "in its own way," setting the brightness on the console according to the HGIG standard is nearly impossible to accomplish as per the instructions. Worse still, in the Dolby Vision mode for games, the input lag rises to about 50 ms, which is a high enough value that essentially makes this mode unusable. However, generally, we wouldn’t recommend gaming on this TV in HDR mode, so these aren’t such serious shortcomings. The most pleasing aspect is the presence of 120Hz in Full HD, which makes the Q80FUX quite a nice TV for the occasional gamer.
