Hisense S7NQ CanvasTV vs Samsung QN80H

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.

The Samsung QN80H is undoubtedly a bright TV. In synthetic tests it exceeds the 1000-nit mark, which on paper promises a solid HDR effect. In practice the screen really shows its teeth, although it can't fully spread its wings (or its backlight, if you will 🤔) in every condition. Bright, wide scenes make the best impression. Well-lit outdoor shots and brightly lit scenes look really good on it. Brightness then stays around 700 nits, which provides a noticeable step up in quality compared with standard SDR. Problems start in dark scenes with small, pinpoint highlights. The QN80H tends to dim these strongly, in order to protect black depth at all costs. On the one hand this gives better contrast, on the other... you lose dynamics and the brilliance of fine HDR detail. So the TV has considerable potential, but the dimming algorithm can be too restrictive.

Colour gamut coverage

When it comes to colours it's good as well. The QN80H uses quantum dot technology, and in our measurements it covered 93% of the DCI-P3 colour space and about 70% of BT.2020. Today those results aren't exactly jaw-dropping, but in real-world use they're more than sufficient to deliver a vivid, natural image for most films and TV series. Colours are suitably saturated, and after proper calibration they don't look artificial or overly aggressive.

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 settings of the QN80H performed really well, especially compared with the majority of TVs we receive for testing. Of course, our measurements were taken in Filmmaker Mode, and that's the mode we recommend turning on immediately after the initial setup. For SDR material, our sample was set up surprisingly well. The white balance was very even, colours looked natural, and errors were so small they were hard to notice without measurement equipment. The only weaker point was the gamma. In the brighter parts of the image the TV brightened them a little too much, which at times made the picture lose some depth. Still, we'd like most TVs to look this good straight out of the box.

It fared a little worse in HDR. The white balance was still set correctly, so the problem was not with the colours but with the way the QN80H managed image brightness. This was immediately visible on the EOTF chart. The TV brightened large parts of scenes too much, causing the brightest elements to clip. Interestingly, very small points were often dimmed too much at the same time. As a result, some fine details simply disappeared. So the factory Filmmaker mode in HDR is not bad, but it is definitely not as well calibrated as in SDR.

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.

We saw the biggest difference after calibration in HDR Filmmaker mode. SDR was already very good out of the box, so we didn't have much work to do there. In HDR, however, we managed to get to grips with the way the QN80H handled brightness, as it had been over-brightening most scenes. After calibration the picture is calmer, more natural and much closer to how a faithful image should look.

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.

Digital image processing in the Samsung QN80H is handled by the second-generation NQ4 AI processor. It's a chip we already know from the manufacturer's earlier models, and it still performs very well, especially with lower-resolution content. The image is effectively upscaled to 4K, but without excessive sharpening and without giving the impression the TV is aggressively trying to improve the source material.

The "Noise Reduction" function also proves useful. It can noticeably reduce posterisation and visible banding in lower-quality material, particularly in low-bitrate streaming. However, it's important to remember that it does not work without side effects. It can remove some film grain and slightly smooth the image. So with a high-quality source we'd leave this function switched off. If, however, someone is more bothered by banding and uneven tonal transitions than by the loss of some grain, "Noise Reduction" can be a really useful addition.

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.

Motion handling and motion clarity on the QN80H are really good, mainly thanks to the fast panel. In 4K the screen refreshes at up to 144 Hz, and when switched to Full HD and connected to a PC it can reach as much as 240 Hz. That's new for Samsung TVs and a useful addition for people who want to use the TV for PC gaming as well. We were more interested, however, in how the QN80H performs at 120 Hz, because consoles use that refresh rate. Here it performs very well. The panel does not suffer greatly from the smearing typical of VA panels, and light trails behind moving objects are mainly visible on dark backgrounds. That said, it's nothing that would interfere with normal watching of sport or gaming. The TV also has a motion smoothing system that Samsung calls "Wyrazistością obrazu". You can adjust judder reduction and blur reduction separately, so it's easy to tailor its behaviour to films, sport or your own preferences.

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".

The Samsung QN80H is a TV that stands out when it comes to gaming features. The biggest new addition for 2026 is DLG mode, which allows refresh rates of up to 240 Hz when the image is switched to Full HD. It's an option aimed mainly at PC users, but it also shows that Samsung is still heavily developing the gaming side of its TVs. However, the list of advantages doesn't end there. The QN80H has four full-fledged HDMI 2.1 ports, which is still not standard at this price point. So you can connect several consoles, a PC or a soundbar at the same time without having to wonder which port supports the full video capabilities. The TV also supports VRR, ALLM and HGiG, so it's hard to fault its basic feature set.

A downside is the lack of Dolby Vision, which may matter primarily to Xbox Series X owners. However, this is not a flaw that disqualifies the QN80H as a gaming TV. Samsung has a feature most manufacturers still lack: its proprietary motion smoothing, Game Motion Plus. It's a motion smoothing system that works in game mode too, allowing you to improve the smoothness of titles running at 30 or 60 frames per second without a drastic increase in input lag. In practice, Game Motion Plus can make a much bigger difference than the Dolby codec, especially in more demanding games that don't offer a 60 FPS mode. The image becomes noticeably smoother, while controls remain sufficiently responsive. So despite the lack of Dolby Vision, the QN80H remains one of the best-equipped gaming TVs in its class.
