Haier Q80FUX vs TCL C7L

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.

TCL C7L is undoubtedly an extremely bright television. In synthetic tests on static images, it can achieve peak brightness of around 2800 nits. This is an exceptionally phenomenal result, considering the price range it occupies. Unfortunately, tests of real film scenes are not quite as spectacular as measurements of white squares. Brightness in actual HDR shots drops to around 1200 nits in the C7L model. This is still a very good result, as this is the value to which the vast majority of contemporary films are mastered. However, when small, point-like elements appear on the screen, the brightness of these details drastically decreases – even down to around 400 nits – which diminishes the HDR effect somewhat. The television does this deliberately to maintain a better level of black and to avoid a giant light bloom. This is somewhat explainable, but it also shows that Mini LED technology is not entirely uncompromising in this regard. As for the HDR effect itself – alongside brightness, colours are of course key here. And those, thanks to the use of new "super" quantum dots, are simply outstanding and among the best on the market. The television can achieve about 90% coverage of the ultra-wide BT.2020 colour gamut and 99% of the DCI-P3 gamut, easily matching the best RGB MINI-LED screens. Best of all, the C7L can maintain such a high saturation of colours regardless of the scene being displayed, which often poses a challenge for competing RGB Mini-LED televisions.

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.

When it comes to colours straight out of the box, a new feature in TCL televisions – including the C7L model – is the presence of a new picture mode called Filmmaker Mode. This is significant news, as such a mode was not available from this manufacturer before. By design, as indicated by the name itself, the image in this setting is meant to be presented with the full intention of the film's creator. After our tests, we can confirm that it is undoubtedly the best built-in mode on this television if you care about faithful colour reproduction straight out of the box. However, we certainly wouldn't say it is perfect. Like most devices on the market, this C7L also had its factory flaws. The white balance in Filmmaker Mode tended to shift towards a slightly greenish-yellow hue, primarily caused by an excess of green and a clear deficiency of blue. Of course, for the average viewer, this won't be a drastic flaw, but if you care about perfect whites, natural skin tones, and unlocking the full potential of those new "super" quantum dots, then the television is crying out for professional calibration.

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.

After conducting a professional calibration, we were able to significantly improve the situation in the factory mode Filmmaker Mode. Following our adjustments, errors in the ColorChecker test and across the entire wide colour gamut fell below the threshold of human perception – that is, below a value of 3, which is truly an excellent result. The TCL C7L definitely benefits from such an operation in terms of colour fidelity, and this is difficult to dispute. However, the management of brightness in HDR content post-calibration does not look as good. As I described earlier – even though we set up this model appropriately, when we turn on real film scenes on the television, it manages its brightness in quite a peculiar way. It often highlights certain elements on the screen contrary to the creator's intention, which can be clearly seen in the EOTF graphs measured in specific films. Despite this defect – or rather the specific trait of this television – one cannot deny that after calibration, the C7L was able to reproduce colours completely accurately.

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.

This point could be called, in a sense, the Achilles' heel of the C7L model. Unfortunately, this television uses an older chipset from MediaTek – the Pentonic 700 – which has never been known for outstanding digital picture processing. This is clearly visible in the performance of the smoothing function, which is responsible for reducing jagged edges and removing digital noise. It simply works very poorly – when set to a low level, its effectiveness is practically nonexistent. A small credit should perhaps be given here for the fact that the algorithm does not additionally ruin the picture or blur details forcibly. The upscaling, which is the scaling of the image from lower resolutions to 4K, fares a bit better. It is simply adequate and does not stand out in any particular way against the competition. However, it cannot be denied that the C7L would greatly benefit in this aspect if the manufacturer decided to use the newer Pentonic 800 processor, which is now found in an increasing number of competing models.

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.

TCL C7L features a native 4K panel with a refresh rate of 144 Hz, which at lower resolutions – when using a PC – can even ramp up to 288 Hz. These are, of course, very high values and commendable on paper, but in everyday life, it is worth remembering that almost all dynamic content you display on this television will still rotate around a maximum of 120 Hz. To tame this dynamism, the television's menu includes a motion smoothing system called "Motion Clarity." It offers several predefined modes, including a user mode, which we definitely recommend setting manually using our tried-and-tested guides on our YouTube channel. There, we have two key sliders at our disposal. The first one, "Motion Blur Reduction," is responsible for reducing blurring and improving sharpness in dynamic 60-frame materials, such as sports broadcasts. Meanwhile, the second slider, "Flicker Reduction," allows for the addition of artificial frames in films and series recorded at cinematic 24 or 30 frames per second. This certainly eliminates the irritating stutter in images during camera movement shots.

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.

When it comes to gaming, the TCL C7L is simply an outstanding television for gamers. With the presence of two full-bandwidth HDMI 2.1 ports at 48 Gbps, it provides access to all the key features that console and high-end PC owners require. It has a well-functioning ALLM mode with very low input lag and VRR frame synchronization that operates in an impressive range from 48 up to 288 Hz. Importantly, unlike some competitors, TCL has ensured a proper implementation of the console HDR10 HGIG profile and support for Dolby Vision in games. This is complemented by a very well-designed player panel, known as the Game Bar, which even allows you to customise its appearance and change the theme to perfectly match the style of your console.

The only thing that can – and indeed should – be critiqued here is the fact that the television offers only two full HDMI 2.1 ports, while the other two are older HDMI 2.0. This creates quite a significant logistical problem. Why? Because one of those fast ports also supports the eARC audio return channel. In practice, this means that if you connect a soundbar or home cinema system to the television, you will only have one free HDMI 2.1 port left. If you have two consoles or a console and a powerful computer at home, unfortunately, you'll have to give something up or frequently juggle cables at the back of the unit while maintaining convenient control over your audio system.
