Hisense U7Q vs TCL C7L

Since the algorithms responsible for blacks are performing quite well, we expected a similarly good effect when it comes to brightness and overall HDR quality. Unfortunately – here we have to disappoint you a bit.

The U7Q is quite a bright TV – in optimal conditions, it can reach around 800 nits, which indeed impresses on some screens, especially in scenes like those from the movie The Meg. Bright segments can really shine, and the HDR effect is noticeable. The problem arises when very small, bright elements appear on a dark background – for example, in Sicario 2 or in the second scene of the movie Life of Pi. In such moments, the dimming algorithms operate too aggressively. Yes, the blacks look great then, but the brightest points can almost completely fade, causing the HDR effect to disappear and details to be barely visible. That's just the nature of this technology in this price segment.

As a consolation, it's worth adding that the U7Q is advertised as a QLED TV (in practice, a PFS layer is used, which works very similarly), and it is indeed capable of displaying a wide color palette – with DCI-P3 coverage at around 94%, that's a very good result for this class.

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

We tested the U7Q in the best possible picture mode, which is Filmmaker Mode. This mode is supposed to provide the most "filmic" experience and fidelity to the creators' intent – right out of the box. Unfortunately, even this professionally sounding name does not guarantee a perfect picture.

In our unit, the problem lay in a poorly set white balance. Both in HD and 4K content, the image had too much blue and red, giving the screen a slightly pinkish hue. It didn't look terrible, but it was noticeable – especially in bright scenes and white backgrounds. This alone could have been forgiven, but the biggest issue is the management of brightness in HDR content. The EOTF curve from the measurements confirms what we saw earlier during the scene tests: the television often dims the smallest bright elements too much, causing them to almost disappear, or conversely – excessively brightens the brightest ones, affecting the naturalness of the image.

When it comes to colors straight out of the box, what's new in TCL TVs, including the C7L model, is the addition of a picture mode called Filmmaker Mode. That's significant because until now that mode wasn't available from this manufacturer at all. In theory, as the name suggests, the image in this setting is meant to represent the filmmaker's full intent. From our tests we can confirm that it's without a doubt the best built-in mode on this TV if you care about faithful color reproduction right out of the box. However, we wouldn't say it's perfect. Like most devices on the market, this C7L also had some factory issues. The white balance in Filmmaker Mode tended toward a slightly greenish-yellow tint, caused mainly by an excess of the green channel and a noticeable lack of blue. For the average viewer this won't be a drastic flaw, but if you care about perfect whites, natural skin tones, and getting the full potential out of the structure of these new "super" quantum dots, the TV really begs for professional calibration.

Thanks to specialized tools, we managed to correct the color quality in SDR content to nearly perfection. In materials with lower dynamics, delta E errors dropped below 0.5, which can be considered an almost reference result. The image on television, YouTube, or classic Full HD looks really good after calibration. Well, but where couldn’t we improve the image so easily? Primarily, it concerns HDR quality content. While we managed to somewhat "tame" the white balance and eliminate pink hues in most scenes, unfortunately, we did not have full control over brightness management. We set the local dimming settings according to the best observations – SDR: Medium, HDR: High – but the U7Q still did everything a bit its own way. There were still cases of overly strong dimming or brightening of details that the calibration simply couldn't eliminate. And although the overall reception of the content is much better, it must be taken into account that the U7Q will always have something to say at the end "but."

After a professional calibration we were able to greatly improve the out-of-the-box Filmmaker Mode. After our adjustments, errors in the ColorChecker test and across the wide color gamut fell below the threshold of human perception, that is below a value of 3, which is a very good result. The TCL C7L definitely benefits from this treatment in terms of color accuracy, and that's hard to argue with. A bit worse, however, is the issue of brightness management in HDR content after calibration. As I described earlier, even though we set this model up correctly, when you play real movie scenes on the TV it can manage its brightness in a rather peculiar way. It often brightens certain elements on the screen contrary to the creator's intent, which can be clearly seen on EOTF charts measured in particular films. Despite this flaw, or rather a specific quirk of this TV, you can't take away one thing: after calibration the C7L was able to reproduce colors accurately.

There are situations where we would like to smooth out tonal transitions a bit, especially in older materials – those that have limited source quality. The U7Q is equipped with a feature called “Smooth and Gradient Image,” but unfortunately… it works very poorly. In the “Low” option, the effects are practically unnoticeable, and other settings smooth out details but do not improve tonal transitions. The only plus is that the feature does not interfere with film grain, so it does not ruin the natural structure of the image.

Fortunately, content scaling performs quite well. The image is not overly sharpened, there is no artificial clarity – and although it is known that this is not the level of high-end televisions, the U7Q handles displaying really old content in a completely acceptable manner without any problem.

This point could, in a sense, be called the Achilles' heel of the C7L. Unfortunately, this TV uses an older MediaTek chipset, the Pentonic 700, which was never known for outstanding digital image processing. You can clearly see this in the operation of the gradual smoothing function, which is responsible for reducing jagged edges and removing digital noise. It simply performs very poorly; when set to low, its effectiveness is practically nonexistent. The only small plus is that the algorithm doesn't further degrade the image or forcefully blur details. Upscaling itself, meaning the scaling of lower-resolution content to 4K, performs a bit better. It's simply adequate and doesn't stand out compared with the competition. That said, there's no denying the C7L would gain a lot in this area if the manufacturer decided to use the newer Pentonic 800 processor, which is now appearing in an increasing number of competing models.

U7Q is truly a fast television, similar to its more powerful version "PRO". At a resolution of 4K, it supports up to 144 Hz refresh rate, and if someone wants even more – in Full HD you can achieve up to 240 Hz! This will mainly benefit PC gamers, but it’s worth appreciating – this is a rare feature in this price segment. Right from the start, it’s clear that U7Q was created with dynamic content in mind, such as games or sports. In films, we are not left "out in the cold" either – U7Q offers the "Ultra Motion Smoothness" feature, where using two sliders you can adjust whether you want a smoother, theatrical image, or something closer to a cinematic style with a visible frame. It’s good that, like with most manufacturers, we have a choice here and can adjust it to our own preferences.

The TCL C7L uses a native 4K panel with a 144 Hz refresh rate, which, at lower resolutions when using a PC, can even reach up to 288 Hz. Those are obviously very high numbers and look impressive on paper, but in everyday use it's worth remembering that almost all dynamic content you play on this TV will still run at around a maximum of 120 Hz. To tame that motion, the TV's menu includes a motion smoothing system called "Motion Clarity." It offers several predefined modes, including a user mode that we strongly recommend setting manually using our tried-and-true guides on our YouTube channel. There are two key sliders available there. The first, "Blur Reduction," reduces smearing and improves sharpness in dynamic 60-fps material, such as sports broadcasts. The second slider, "Flicker Reduction," lets you add artificial frames to movies and TV series shot at cinematic 24 or 30 fps. This, of course, allows you to completely eliminate the annoying image judder during camera motion.

The Hisense U7Q is a TV designed for gamers – and you can see that right away based on its gaming capabilities. It has practically everything you could wish for: variable refresh rate (VRR) – check, automatic game mode (ALLM) – also check, and high refresh rates of up to 240 Hz in Full HD, as well as support for various resolutions, not just 4K. It's truly a great set of features that makes the U7Q excel in both fast-paced shooters on consoles and more demanding titles on PC. Of course – like in most Hisense models – it lacks a proper implementation of the HGiG function. That's a shame because HGiG allows you to adjust the brightness of the console to the specific TV, which in practice makes displaying HDR games according to the creators' intentions much easier. Without this, you simply have to reckon with certain limitations in the final HDR image in games.

When it comes to gaming, the TCL C7L is simply an outstanding TV for gamers. Thanks to two full-bandwidth HDMI 2.1 ports at 48 Gbps, you get access to all the key features required by console owners and users of powerful PCs. It has a well-implemented ALLM mode with very low input lag and VRR frame-sync that works in an impressive range from 48 to 288 Hz. Importantly, unlike some competitors, TCL implemented the console HDR10 HGIG profile correctly and added support for Dolby Vision in games. Rounding out the package is a very well-designed player panel, the Game Bar, which even lets you edit its appearance and change the theme to perfectly match your console’s style. The only thing you can — and should — criticize is that the TV offers only two full HDMI 2.1 ports, while the other two are older HDMI 2.0. That creates a fairly significant logistical problem. Why? Because one of those fast ports also supports eARC (enhanced Audio Return Channel). In practice, that means if you connect a soundbar or a home theater system, you’ll only have one free HDMI 2.1 port left. If you have two consoles at home, or a console and a powerful PC, you’ll unfortunately have to give something up or constantly juggle cables at the back while trying to maintain convenient control of your audio system.
