Hisense S7NQ CanvasTV vs TCL C7L

When it comes to the brightness of the television and how it handles bright elements while watching films, it's just average – similar to the contrast. The average brightness level of the Hisense S7NQ is around 500 nits. This is a value that allows you to feel the hints of true HDR, but it's definitely not enough to speak of remarkable effects. However, the television should be praised for its colour gamut coverage – films look very colourful and vibrant. Thanks to the use of a PFS LED (QLED) coating, the device is able to cover more than 90% of the DCI-P3 colour gamut and over 72% of the wider BT.2020 palette. For a television of this class – these are really very good results.

TCL C7L is undoubtedly an extremely bright television. In synthetic tests on static patterns, it can achieve peak brightness of around 2800 nits. This is a phenomenal result, considering the price range it occupies. Unfortunately, tests with real movie scenes are not as spectacular as measurements of white squares. Brightness in real HDR footage drops in the C7L model to around 1200 nits. This is still a very good result, as this is the value at 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 drops – even to around 400 nits – which somewhat diminishes the HDR effect. The television does this intentionally to maintain a better black level and to avoid a huge light bloom. 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, colours are of course 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 colour 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 colour saturation regardless of the scene being displayed, which can often be problematic in competing RGB Mini-LED televisions.

Let's check how the Hisense S7NQ CanvasTV performs in terms of colour reproduction in its best factory mode, which is Filmmaker. Right from the start, it’s clear that it’s definitely better than in dynamic or standard mode, but there are still a few things to nitpick. In terms of image quality from HD signals, the colours are slightly skewed – there’s a dominance of cooler blue tones and a lack of red. This makes the image seem a bit too cool.

A similar effect is noticeable in 4K content, but it’s more pronounced there. The excessive exposure of blue tones and lack of red makes the image appear distinctly cold. However, the biggest issue with this TV isn’t the colours themselves but the way brightness is managed. The unit we tested slightly increased brightness compared to the reference value. The result of this is indeed better visibility of details, but at the cost of significantly lighter blacks – which makes the entire image seem more "flat."

A similar phenomenon was observed in the 4K signal – the slightly inflated curve at the beginning of the EOTF graph indicates that the TV has a tendency to overexpose certain scenes. Fortunately, this effect can be improved through professional calibration, which we will discuss in the next point.

When it comes to out-of-the-box colours, a new feature in TCL TVs – 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 previously available from this manufacturer. By design, as the name suggests, the picture in this setting is intended to be delivered with the full intent of the film's creator. After our tests, we can confirm that it is undeniably the best built-in mode in this TV if you value true-to-life 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 faults. The white balance in Filmmaker Mode leaned towards a slightly greenish-yellow hue, mainly due to an excess of green component and a noticeable lack of blue. Of course, for the average viewer, this won’t be a drastic flaw, but if you value perfect whites, natural skin tones, and harnessing the full potential of these new "super" quantum dots from the structure, then the TV is begging for professional calibration.

The results we achieved after calibrating the Hisense S7NQ are really very good. Thanks to the calibration, we managed to eliminate excessive blue tone exposure and deficiencies in red with HD signals. A similar, albeit slightly weaker effect was also achieved with 4K HDR content. Brightness management in HD materials has also improved – the television no longer struggles with brightening the image "overall".

However, there are things that cannot be circumvented. The character of the EOTF curve has hardly changed, and the lack of local dimming means that the smallest elements on the screen will always be slightly overexposed. You just have to come to terms with this when choosing a television with a similar type of backlighting. Nevertheless, the final effect is very good and should fully satisfy the vast majority of users.

After conducting a professional calibration, we were able to greatly improve the situation in the factory Filmmaker Mode. Following our adjustments, the errors in the ColorChecker test and across the entire wide colour gamut dropped below the threshold of human perception – that is, below a value of 3, which is indeed a very good result. The TCL C7L definitely benefits from such a treatment in terms of colour fidelity, and it's hard to deny that. However, the management of brightness in HDR content after calibration appears to be a bit worse. As I described earlier – even though we set this model up properly, when we turn on real film scenes on the television, it can manage its brightness in quite a peculiar way. It often brightens certain elements on the screen in a manner inconsistent with the creator's intent, which is visibly apparent on the EOTF graphs measured in specific films. Despite this flaw – or rather, this specific characteristic of the television – one cannot take away from it: after calibration, the C7L was able to reproduce the colours flawlessly.

Equally important is how the television handles tonal transitions with a poorer signal – for example, in older films, on television, or on YouTube. Unfortunately, despite the presence of the “Smooth and Gradient Picture” feature, which was supposedly meant to improve this aspect, its functionality is really poor. It’s barely noticeable that it has any real impact on the visibility of colour transitions.

The image scaling is also disappointing. Yes, you can see that the television is trying to “pull up” the quality, but the end result is far from ideal. The image often appears slightly jagged, which is particularly noticeable in the example of tree branches in the background. Additionally, the Hisense S7NQ has a clear tendency to crop the image at lower resolutions, which could result in missing subtitles in the news or finer details in the image.

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 image processing. This is clearly visible in the functioning of the gradual smoothing feature, 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 none. The only small plus here is that the algorithm doesn't mess up anything else in the image and doesn't forcefully blur details. The upscaling, that is, the scaling of the image from lower resolutions to 4K, performs 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 being found in an increasing number of competitive models.

When it comes to motion fluidity, the television performs really well. Although the S7NQ was primarily designed for displaying static elements – such as images – the manufacturer has used a panel with a refresh rate of 144 Hz. As a result, sports or games look really good on it.

For content that is not recorded at a high frame rate, the manufacturer has provided two features that allow you to adjust the picture to your own preferences. “Motion blur reduction” and “blur” operate on a 10-point scale, enabling a choice between a more cinematic image – with characteristic frame jumps – and a smooth effect reminiscent of a “soap opera.” How to set this up? That’s a personal choice – we leave the decision to you.

TCL C7L features a native 4K panel with a refresh rate of 144 Hz, which can even ramp up to 288 Hz at lower resolutions when using a PC. These are certainly very high and commendable figures on paper, but in everyday life, it's worth remembering that almost all dynamic content you display on this television will still revolve around a maximum of 120 Hz. To tame this dynamism, the TV menu includes a motion smoothing system called "Motion Clarity." It offers several predefined modes, including a user mode, which we highly recommend setting manually using our tried-and-true guides on our YouTube channel. You’ll find two key sliders available. The first one, "Motion Blur Reduction," is responsible for reducing blurring and improving sharpness in 60fps dynamic content, such as sports broadcasts. The second slider, "Flicker Reduction," allows for the addition of artificial frames in movies and shows recorded at cinematic 24 or 30 frames per second. This naturally allows for the complete elimination of the annoying stutter effect during camera movement shots.

Even though the S7NQ is an "image" type television, you can actually play games on it. Really. It has practically everything (except for HGiG mode) that a modern gaming television needs. The 144 Hz panel and two full HDMI 2.1 ports allow for seamless connection of two consoles, such as the PlayStation 5 or Xbox Series X/S.

The television supports Automatic Low Latency Mode (ALLM) and Variable Refresh Rate (VRR) without any stutters or issues. It also handles high frame rates at lower resolutions without any trouble. A shoutout to Hisense for the very attractive Game Bar – it displays all available image options, and additionally, we have the ability to enlarge the minimap or turn on the crosshair (because sometimes someone might actually want to "aim" 😉).

The only missing element – as we mentioned earlier – is the lack of proper implementation of HGiG mode. This is the feature responsible for automatically setting the image in games as the developers intended. It’s a shame because it's the only thing that separates the Hisense S7NQ from being a full-fledged gaming "monster".

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. We have a well-functioning ALLM mode with very low input lag and VRR frame synchronization, which operates within an impressive range from 48 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 gamer panel, known as Game Bar, which even allows for editing its appearance and changing the theme to perfectly match the style of your console.

The only thing that can – and should – be critiqued here is the fact that the television only offers 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 theatre system to the television, you’ll only have one available 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 constantly juggle cables at the back of the unit while maintaining comfortable audio system control.
