Hisense S7NQ CanvasTV vs Samsung Q7F

When it comes to the brightness of the television and how it handles bright elements while watching films, it is simply average – similar to the case with contrast. The average brightness level of the Hisense S7NQ is around 500 nits. This is a value that allows one to feel the beginnings of true HDR, but it is definitely too little 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 PFS LED (QLED) coating, the device is capable of covering over 90% of the DCI-P3 colour palette and over 72% of the wider BT.2020 palette. For a television of this class – these are really very good results.

Unfortunately, the Samsung Q7F is not one of the brighter televisions, and this has a direct impact on the quality of HDR films. The peak brightness of the panel is just around 250 nits, which is definitely too low to speak of true cinematic experiences. In practice, the image in HDR content does not differ significantly from classic SDR, making it difficult to talk about any "wow effect" that usually accompanies us when watching such films. During tests of film scenes, the image simply looked dark, and the brightness almost always hovered around the aforementioned 250 nits. The worst performances were with shots that included small, intensely shining elements – the global dimming technique used reacted very aggressively in these cases, dimming the entire screen to maintain the effect of black. However, it is worth noting the presence of the QLED coating that expands the colour palette. For a budget QLED model, the Q7F performs quite decently here: the coverage of the DCI-P3 palette is about 93%, and BT.2020 reaches 70%. This means that, despite the low brightness, the colours can still look quite vivid and attractive.

Let's now check how the Hisense S7NQ CanvasTV performs in colour reproduction in the best factory mode, which is Filmmaker. Right from the start, it is clear that it is decidedly better than in dynamic or standard modes, but there are still a few things to nitpick. Regarding image quality from an HD signal, the colours are slightly inaccurate – there is a dominance of cooler shades of blue and a lack of red. This makes the image appear somewhat too cool.

A similar effect can also be observed with 4K content, but there it is much more noticeable. The excessive exposure of blue tones and the lack of red result in the image appearing distinctly cold. However, the biggest problem with this television is not the colours themselves but the way brightness is managed. The tested unit slightly boosted brightness compared to the reference value. While this results in better visibility of details, it comes at the cost of significantly brightened blacks – causing the entire image to seem more "flat".

A similar phenomenon was noticed in the 4K signal – the slightly elevated curve at the beginning of the EOTF chart shows that the television has a tendency to overexpose certain scenes. Fortunately, this effect can be improved with professional calibration, which we will discuss in the next point.

The factory colour accuracy of the Samsung Q7F is certainly not one of its strong points. In Filmmaker mode, which theoretically should be the closest to neutral, the issue with white balance immediately stands out. There is too much red on the screen, while blue is lacking. The consequences of this are very easy to notice – white, instead of being neutral, takes on warm, almost slightly orange tones. In the long run, this makes the entire image look somewhat unnatural, and bright areas of the scene may seem unrealistic. The problems become even more evident in HDR content. The graphs show that the television has significant errors in the Color Checker palette, which translates to visible inaccuracies in the actual image. Practically, this means that the colours are not presented as they should be. The Q7F also heavily manipulates brightness; darker elements are overly boosted, losing their cinematic quality, while bright parts may appear dimmed. As a result, the image seems flattened, and contrast, instead of helping to bring out details, only highlights its own limitations. This is particularly frustrating in HDR material, where every detail matters. In scenes where there should be a subtle play of light and shadow, the Q7F either oversteps by brightening too much or conversely – suppresses elements that should draw the eye. This causes the image to lose its depth, and instead of cinematic realism, we have a rather simplified effect.

The results we achieved after calibrating the Hisense S7NQ are really very good. Thanks to the calibration, we managed to eliminate the excessive exposure of blue tones and deficiencies in red with HD signal. A similar, albeit slightly weaker effect was also achieved with 4K HDR content. Managing brightness in HD material has also been improved – the television no longer has issues with brightening the image "across the board."

However, there are things that cannot be bypassed. The characteristic of the EOTF curve has practically not changed, and the lack of local dimming means that the smallest elements on the screen will always be slightly overexposed. One simply has to come to terms with this when choosing a television with a similar type of backlighting. Despite this, the final effect is very good and should fully satisfy the vast majority of users.

After professional calibration, we managed to bring the Q7F into order – at least in terms of SDR content. The picture in this mode looks really good: the white balance has been set correctly, the colours appear natural, and errors in the colour palette have dropped to levels that are practically invisible to the eye. Gamma behaves exemplary, and the only minor drawback is a slight lightening of smaller elements, which results from the lack of local dimming. For everyday watching of television or films in standard quality, the Q7F performs surprisingly well.

It was significantly harder to tame HDR content. Despite adjusting the white balance, the television still heavily manipulates brightness, causing scenes to sometimes look unnatural – what should be subtly darker can be overly brightened, and bright areas of the picture can occasionally appear dimmed. The end result is better than in factory settings, but it is evident that the structural limitations of the Q7F do not allow for the full potential of HDR materials to be fully realised.

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

The image scaling is also lacking. Yes, it can be observed that the television tries to "enhance" 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, causing subtitles in news items or finer details in the image to be missed.

Upscaling and digital image processing on the Q7F is a bit of a sine wave. On one hand, we have really nice upscaling – weaker sources look better than one might expect. The image becomes clearer, sharper, and even older films or terrestrial television perform adequately. Samsung has been strong in this area for years, and the Q7F confirms that. On the other hand… there are some issues. The television has a problem with overscan – part of the image is simply cut off, and it doesn't look very elegant. Additionally, we were let down by a feature called "noise reduction", which should improve the smoothness of tonal transitions in weaker materials. In other Samsungs, it works relatively well, but here it makes practically no difference – the banding in gradients is still there. It's a bit of a shame, as one could have expected more from a model that is aimed at users looking for a display for SDR content.

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

For materials that are 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 "judder reduction" operate on a 10-point scale, allowing you to choose 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 matter – we leave the decision to you.

Ghosting and motion smoothness in the Q7F are probably the most budget-friendly elements of this television. The 60 Hz panel makes itself known, with noticeable ghosting, especially in dynamic scenes, and it's rather difficult to regard this model as equipment designed for watching sports or playing fast-paced games. In tests with the little green man, a long trail was left behind, similarly to how a ball in a football match would leave streaks.

On the plus side, the presence of motion smoothing must be acknowledged. In films, it actually makes a difference – especially since most material is recorded at 24 frames per second. Here we can decide whether we prefer a more "cinematic" image, with slight judder typical of cinema, or a smoother, more "television" approach. This part works quite well and helps to improve the viewing experience for series and films.

Although the S7NQ is a "picture" type television, it can indeed be used for gaming. Really. Here you can find almost everything (except for the HGiG mode) that a modern gaming television needs. The 144 Hz panel and two full-fledged HDMI 2.1 ports allow for the hassle-free 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), with no stuttering or issues. It also handles displaying high frame rates at lower resolutions without any trouble. Hisense deserves praise for a very attractive Game Bar – it displays all available picture 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 a proper implementation of the HGiG mode. It is specifically responsible for automatically adjusting the picture in games as the creators intended. It's a shame, because that’s the only thing preventing the Hisense S7NQ from being a full-fledged gaming "beast".

Features for gamers in the Samsung Q7F is a topic that evokes quite a lot of mixed feelings. On the one hand – no sensible person expected miracles here, as it is after all a 60 Hz television and it was clear from the start that it would not be a device for squeezing the maximum out of a console or PC. On the other hand, since the manufacturer promised specific solutions in promotional materials, it is natural that we wanted to see them in practice. At the outset, it’s quite decent. The automatic game mode (ALLM) works, so there’s no need to manually fiddle with the settings; the console automatically switches the television to low-latency mode. Additionally, we have the Game Bar, which looks impressive and allows you to check a few basic parameters without leaving the game. And this is where the good news ends.

The biggest problem with the Q7F is VRR, or rather its absence. Yes, an appropriate icon appears in the menu, and you can even see it in the Game Bar, but throughout the entire test, the feature remained inactive and could not be enabled in any way. The situation with HGiG is even more painful; this option was indeed available at the beginning, but after a software update, it completely vanished, which is simply unprofessional. Therefore, the Q7F is only suited for the absolute basics. Of course, you can turn on the console, play some calmer titles, and enjoy low input lag, but if someone is counting on more advanced features that the manufacturer promised, they will be disappointed. This is not a television to buy with gaming in mind, and it's better to be aware of that before making a purchase.
