TCL V6C vs Haier Q80FUX

When it comes to HDR, the TCK V6C clearly shows that it is not its strong suit. A peak brightness of around 200 nits makes it difficult to talk about true HDR effects – the picture simply remains too dark to bring out details in bright scenes or convey the appropriate dynamics. Although the television formally supports many HDR formats, it is not practically equipped for such demanding content. The lack of additional layers that enhance colors, such as QLED or PFS LED, further limits the appeal of the image – in more spectacular productions, the colours may seem washed out compared to more expensive models. Therefore, the V6C will primarily serve as a television for everyday viewing, YouTube, or SDR content, rather than as equipment for high-quality cinematic experiences.

Alright, let's move on to the topic that really sparks discussions, which is the capabilities of the TV in HDR mode. Let's be clear from the start: the Haier Q80FUX is certainly not a brightness demon. The panel of this set can generate about 350 nits at peak, which in today's reality is an absolute minimum to even talk about the presence of HDR expanded dynamic range. On the plus side, this brightness is at least stable – regardless of the test pattern or film scene we used, measurements consistently hovered around 300-350 nits. These are at best adequate results, definitely far from the dazzling display of capabilities that we know from more expensive models. Fortunately, there is one aspect where the Q80FUX makes up for these shortcomings and does so considerably. We are talking about a QLED TV (or more precisely PFS LED), which means that thanks to the quantum dot filter used on the panel, it can generate truly juicy, vibrant colours. These are not empty promises – covering nearly 95% of the DCI-P3 colour gamut is an impressive result and directly translates into very pleasant, saturated colours for the eye.

We started colour reproduction tests with the Filmmaker mode, which in theory should be the best choice straight out of the box. It certainly performs better than the Eco or Dynamic modes, which heavily interfere with the image and spoil its natural character. As you can see in the graphs, the factory tuning of the V6C is not ideal, although it's not a disaster either. The biggest issue turned out to be a lack of red – the TV clearly "cools" the image, which is especially noticeable on human faces, giving a "zombie skin" effect. This particular issue was the most bothersome during everyday viewing. Looking at the colour palette in HDR content, the shortcomings in red are also noticeable, and their source is the relatively narrow coverage of the colour space. Of course, every TV can be calibrated, so we decided to check how the V6C would perform after such an adjustment.

Factory settings for movie mode are seldom perfect, but in the case of the Q80FUX, we encountered a noticeable imbalance. In SDR content, the image was definitely too warm, due to an excessive amount of red in the white balance, giving the overall picture a slight sepia tone. Conversely, in HDR materials, the television fell into the other extreme – an excess of blue caused an unnatural, cool effect in perception. However, it wasn't the fickle white balance that was the biggest issue with this TV. The real culprit, responsible for the previously described problems, 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 the notorious clipping of the brightest parts of the image, imposing that characteristic milky filter over them. Thus, we found the source of the problem. This situation led to general, significant colour inaccuracies 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 these adjustments in the next paragraph.

My dear friends – we haven't faced such a difficult "calibration battle" in years. The V6C turned out to be one of the most stubborn TVs we've dealt with in the office. The calibration trials alone took us several hours of work and required a lot of patience. We finally managed to slightly warm up the skin tones, which made faces stop looking like they were pulled straight out of a horror film, a common issue with the factory settings. Unfortunately, that wasn't the end of it – the TV reacted to our adjustments in white balance in a completely unpredictable manner. Where we expected stability in the image in a certain area, new errors appeared, and Color Checker measurements showed deviations that couldn't be rationally explained. It's hard to say whether the fault lay with the software or the design itself, but one thing is certain – the V6C put up exceptionally strong resistance. Ultimately, the calibration brought improvement, especially in SDR content, where the image became more pleasing and natural. However, it must be clearly stated that the design limitations remain. The TV still flattens the image in HDR materials and has noticeable deficiencies in colour reproduction. This is equipment more suited for everyday TV watching or SDR content rather than for cinematic experiences in the highest quality.

The results of our calibration procedures must, unfortunately, be regarded as twofold. Generally speaking, the picture is undeniably better than before the adjustments; however, the biggest winner of this process has been SDR content. It is precisely here, after correcting the gamma curves and white balance, that we achieved results that can safely be called very good. Once set up, the Q80FUX truly shines in standard dynamic range, displaying only slight errors in the most challenging skin tones. Unfortunately, the weakest link remains HDR content. And here's the paradox: even though we managed to calibrate the white balance to near perfection, the overall colour errors still remain at quite a high level. The reason is that the television still interprets the static HDR10 metadata "in its own way," stubbornly enforcing that unfortunate image clipping effect, which inevitably leads to significant distortions. Although we successfully eliminated the factory excess of blue, due to this electronic interference, the screen can still veer into somewhat too cool tones. That’s just how this television is.

When it comes to upscaling, the V6C doesn't bring anything groundbreaking to the table. Lower quality content is heavily sharpened, making the image look quite unnatural, at times almost artificial. This can be somewhat alleviated by reducing the sharpness level in the settings, but the effect isn't spectacular. The image still falls short of perfection. The digital processing itself performs better. The function responsible for smoothing tonal transitions works quite effectively, especially at the medium setting, where the image truly appears smoother. Unfortunately, its operation is rather aggressive – it heavily interferes with the overall scene, causing actors in the foreground to start looking like characters from super smooth soap operas. Therefore, we would not recommend using this option if a natural viewing experience is important to us.

If there's one area where Haier clearly shows it still has a lot to catch up on compared to the market leaders, it's digital image processing. The upscaling, well... it's just okay. And that's really all that can be said about it. It does what it's supposed to do: ensures that lower resolution signals don't scare you with harsh pixelation on the screen and don't look like a forcibly enlarged postage stamp. However, it's far from the finesse and "intelligent" sharpening that more experienced players in this market have developed over the years. The biggest issue with the Q80FUX software is the almost complete lack of additional "cleaning" and smoothing features for the image. The receiver offers no noise reduction mechanisms or gradient enhancement. This means that with older or highly compressed materials, we simply have to accept that all the imperfections in tonal transitions or colour blending, which we mentioned earlier, will constantly accompany us during viewing.

Smoothing and motion fluidity are areas where the V6C quickly reveals its limitations. It's a 60 Hz TV, so it was hard to expect miracles here. In dynamic sports scenes, the image performs rather mediocrely. This is most noticeable in darker scenes, where distinct trails and blurred "halos" follow moving objects, which can be quite distracting. This is definitely a weaker point of this model. Fortunately, there is also a small plus. The V6C is equipped with a motion smoother that works while watching movies. Thanks to it, productions filmed at 24 frames per second, which is practically all cinema titles and series, can look smoother than they were actually recorded. Importantly, the intensity of the effect can be adjusted to personal preferences – from slight smoothing to the full "soap opera effect."

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 (although, as will soon become clear, really just one) intended to enhance the experience with older film productions. There is a "De-Judder" slider available, which indeed affects motion fluidity 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 right next to it in the menu. There is also a second slider, supposedly dedicated to removing blur – this is a feature we typically encounter in 120Hz panels, aimed at combating blurring in sports. As we expected, recalling memories from testing the K85F model, here too this slider is merely a façade. Its adjustment contributes absolutely nothing to the picture and simply seems to be an oversight by the product engineers who left a non-functional option in the software for this type of panel.

Even though the V6C is not a TV designed with avid gamers in mind, TCL has included a few features that may appeal to more casual users. You'll not find a 120 Hz panel or HDMI 2.1 ports here, but there is an ALLM mode that automatically switches the TV into low latency mode. There's also a quite practical Game Bar – a simple panel allowing the preview of basic parameters, changing the picture mode, or even enabling a virtual crosshair on the screen. Another interesting feature is the support for Dolby Vision Gaming, intended for Xbox Series S/X consoles – a nice addition, although in practice it doesn’t offer as much as in more expensive models. However, the biggest issue remains the HDR configuration. The HGiG function, responsible for adjusting the brightness and contrast of games to the capabilities of the panel, doesn't respond as we would expect – the picture can be overly dark or too flattened. As a result, a better solution turns out to be simply playing in SDR mode, where the V6C operates steadily and doesn’t try to pretend to be an HDR TV.

Entering the realm of gaming, the Haier Q80FUX proves to be quite a good companion for the "casual gamer." It is equipped with some highly sought-after features today such as VRR (variable refresh rate) and ALLM (automatic low latency mode). However, the biggest surprise is something else. Even though we don't have a 4K@120Hz panel here, the television can accept and display a 120Hz signal at a lower resolution (Full HD). This is a very useful feature, allowing you to consciously switch 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 additions like the "Game Bar," as it's just a nice extra. However, the most concerning issues arise when we enter the world of HDR in gaming. Due to the fact that the television continuously adapts the signal "in its own way," setting the brightness on the console according to the HGIG standard is almost impossible to accomplish according to the instructions. Worse still, in Dolby Vision mode for gaming, the input lag increases to around 50 ms, which is a high enough value that essentially makes this mode unusable. Generally speaking, we still wouldn't recommend gaming on this television in HDR mode, so these aren't that serious shortcomings. What’s most pleasing is the presence of 120Hz in Full HD, making the Q80FUX quite a cool television for the occasional gamer.
