Samsung Q8F vs Haier Q80FUX

In terms of brightness, the Samsung Q8F performs surprisingly well for a television without local dimming. It measures up to 500 nits, which practically means that most movie and series scenes look pleasant, and it definitely cannot be accused of lacking the "HDR effect." In films like Life of Pi or The Meg, the screen was able to glow and deliver light effects at a satisfying level. It struggles more during challenging moments—with dark frames containing single bright points. The global dimming used causes the television to darken the image to maintain deep blacks, but at the cost of detail brightness. This is clearly visible in the scene from Sicario 2, where the helicopter lights dropped to around 200 nits. This is a conscious design decision that gives the impression of deeper blacks but somewhat takes away from the brilliance of individual elements, and this should simply be kept in mind. When it comes to color reproduction, the Q8F utilizes quantum dot technology, which broadens the color range. A DCI-P3 coverage of 91% can be considered a decent result, although it is not a record-breaking achievement compared to other QLEDs.

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 decided to check the Filmmaker mode because it provided us with the best picture right out of the box. However, this does not mean it was perfect. The white balance had too much blue and red tint, causing the white to take on a slight purple-pink hue. Such an imbalance affected the visibility of practically all colors, as can be seen in the comparison photo below. The brightness characteristic in SDR content was quite well adjusted, although in HDR materials, we noticed that the television did not always manage its global dimming—at times, the screen was too dim, while at other times it suddenly brightened. Fortunately, issues related to colors can be effectively corrected with calibration tools, so we decided to get to work.

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 calibration, we managed to correct the white balance almost to perfection. Older SDR content looks stunning — most errors are within a threshold of 2, which is definitely below the human eye's perception limit. In HDR, we also brought the white balance to the correct level, but a different problem arises here. So why are there still relatively large errors in color reproduction? This is mainly due to the limited color palette and the way the television manages brightness. The applied global dimming technique does not give the user control in the settings, so when analyzing the EOTF curve in HDR films, it is clear that the Q8F can independently modify luminance. This can be considered a certain limitation, but despite this, the image after calibration is still much more enjoyable than in the factory version.

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.

Let's see how the Q8F handles older content, which often has poor quality. Let's start with the positives: the upscaling, which means raising the image to a higher resolution, works really well. The TV handles both classic television and materials from YouTube without giving the impression that we are dealing with something completely unattractive. Materials in very low resolutions, such as 576p, perform worse — the image can be cropped, and unfortunately, the overscan phenomenon cannot be turned off. However, the digital processing itself looks worse too. The noise reduction function, instead of removing unwanted interference, smooths out almost everything: film grain (which is desirable for many viewers) disappears along with the texture of the image, and the faces of the actors begin to resemble characters from cheap Turkish soap operas. It is therefore hard to consider this option useful — it's best to leave it completely turned off. Perhaps Samsung will refine the operation of this feature in updates, but for now, it’s difficult to regard it as anything other than an unnecessary addition.

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.

Due to the 60 Hz panel, it's hard to call the Q8F a television made for gaming or watching sports. The panel isn't particularly fast, making motion blur clearly visible. If you were counting on spectacular, almost "stadium-like" experiences during broadcasts, you might feel a slight disappointment. Fortunately, in the case of movies and series, Samsung has not abandoned motion smoothing features. This is nothing other than a motion smoother that allows improving the fluidity of productions recorded at 24 or 30 frames per second. Thanks to this, one can decide whether they prefer a smoother, "television" image or to maintain a cinematic quality. It all depends on the viewer's preferences, and the ability to adjust this parameter is undoubtedly a plus.

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.

[UPDATE] We have updated our 2025 Samsung TV reviews following the release of firmware version 1131, which officially restores the essential HGiG (HDR Gaming Interest Group) support.

It is not entirely clear what Samsung has mixed up this year with its televisions, but the Q8F is not free from all the confusion with updates and shortcomings. While its older cousin, the Q67D, could still be recommended to casual gamers with a clear conscience, it's hard to find a reason to do so here. Aside from the automatic game mode and the attractively designed Game Bar, we practically get nothing that could attract gamers. The lack of proper HGiG implementation is a big problem, especially since function simply disappeared after the 1126 update. The issue with VRR is even worse. Although it is featured in the manufacturer's brochures and appears in the Game Bar, we couldn't activate it. The Xbox Series X console did not allow it to be activated at all, and the option remained grayed out and inactive. It's hard to praise such a television even to casual gamers, which is a shame because Samsung has had a strong bargaining chip in the gaming segment for years.

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.
