Haier Q80FUX vs Samsung Q6F (IPS)

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.

Unfortunately, the Samsung Q6F is a very dark model. Its peak brightness in HDR does not exceed 250 nits, which is definitely too low to even speak of any "high dynamic range" effect, or HDR. In practice, it's better to stick to content in SDR format, which simply looks more predictable on this TV. Another problem is the global dimming technique – in scenes with a lot of black, the TV drastically dims the entire panel to artificially improve the black levels. This causes the image to become even darker, and brightness can drop below 100 nits. The only consolation is the QLED technology, but even here it's average. The applied quantum dot layer is not top-notch, as the coverage of the DCI-P3 color gamut does not exceed 90%. As a result, colors in HDR content may just seem under-saturated.

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.

We tested the television in Filmmaker mode, which showed us two completely different faces of this model. Looking at SDR content, we were honestly shocked at how good this TV looks straight out of the box. It was really hard to nitpick anything here. Despite a slight “haze” in the white balance or somewhat brightened details in the blacks (which directly results from the IPS panel's design), color errors hovered around the “2” level. This is surprisingly good, even outstanding, considering the price of this device.

On the other hand, what the Q6F displayed in terms of colors after switching to HDR mode was a very unpleasant surprise. The errors in color reproduction and palette were so huge that our charts literally ran out of scale. Of course, since Samsung even in such an inexpensive model offers very advanced calibration possibilities, we decided to approach the subject professionally and check what could be done about it during calibration.

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.

After our calibration, the colors in SDR mode looked even better – the result is quite surprising, as color errors at level "1" are something usually seen in devices costing several thousand dollars. In this regard, the Q6F is really a great screen for everyday television, less demanding series, or movies. Unfortunately, our interference in HDR mode did not bring about a noticeable improvement. The television, due to its poor black levels and low coverage of a wide color gamut, still has significant problems with proper color saturation, especially red. This is an example of a device where HDR mainly exists as a label on the box – for everyday use, we definitely recommend watching content in SDR format.

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 Q6F handles upscaling lower resolution content to native 4K very well. The scaling is surprisingly good here, even for such a budget TV from the QLED series. The only downside is when we watch very low-resolution material, like 576p (typical for old DVD players) – then the image may be slightly cropped. This is because the TV does not allow for the Overscan feature to be turned off, which is a common issue with Samsung devices.

The situation is completely different when it comes to digital processing, which is the attempt to smooth the image from unwanted artifacts. Here, the TV completely fails. Although we find a function in the menu called "Noise Reduction", it yields no visible results regardless of the slider setting. The only thing it seems to do is introduce unwanted errors into the image. Despite its presence in the system, we definitely do not recommend using it.

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.

The 60 Hz panel in the Samsung Q6F is the standard in this price range, which makes it a rather average model for dynamic sports or gaming. However, in the case of movies, the TV performs quite well thanks to the smoothing feature. The "Motion Smoothing" option allows you to adjust the fluidity of motion to your own preferences – from maintaining a cinematic feel to full fluidity.

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.

We won’t beat around the bush – the Q6F is not a television designed with gamers in mind. While it does have features like ALLM (Auto Low Latency Mode) and VRR frame synchronization for consoles, the list of benefits pretty much ends there. Besides these basics, the TV offers nothing more that might satisfy those who spend a lot of time in front of a console. It’s a real shame that such a useful tool as Game Bar is missing here, which in Samsung’s higher models allows for quick control of game parameters. In terms of gaming, this is an absolutely basic model and is only suitable for "casual" gamers.
