LG UR781 vs Hisense S7NQ CanvasTV

In HDR mode, LG UR781 unfortunately does not impress with its brightness. In tests on five screens, the television achieved only around 200 nits, which is quite a low value for HDR standards. This brightness is comparable to levels typical for SDR, which means that HDR effects are not sufficiently vivid, and the picture may look less impressive, especially in dynamic, bright scenes. In HDR mode, it has certain limitations in colour reproduction. This means that colours may not be as intense and rich as in televisions that handle a wider colour gamut better. In practice, this can make the image less vibrant and dynamic, and HDR effects may not be as spectacular as one might expect. Additionally, UR781 LG has some issues with accurate colour representation in HDR mode, which makes content look less lively.

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.

Colour reproduction in LG UR781 in Filmmaker Mode, which although it is the best mode available from factory settings, is not without its flaws. First and foremost, the issue is with white balance, where the graph shows dips in the blue colour level. This phenomenon results in a shift towards yellow hues, making the image warmer than it should be. Such deviation means that the colours on the screen are not reproduced naturally, which may be particularly noticeable in scenes with white or neutral backgrounds. This can be confirmed by the Color Checker Test, which showed that some colours "escape" into other shades, indicating that the LG UR781 TV does not display colours accurately. This distortion can affect visual experiences, making film scenes seem less realistic and details may be displayed in incorrect colours, negatively impacting overall picture quality.

In terms of contrast, analysis of the gamma graph revealed drops to a level of 2.0, while the optimal value should be 2.4. This means that the TV may display darker parts of the image brighter in some scenes, reducing their depth and dynamism. Additionally, on the EOTF curve, which is responsible for brightness reproduction, an unnatural spike was noticed at the beginning. This phenomenon may result in excessive brightness boosting in the brightest parts of the image, leading to a loss of details in very bright scenes.

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.

After calibration, colour reproduction in SDR content is quite good. The white balance has been effectively improved, resulting in natural, balanced hues across different scenes. The gamma has also been adjusted, providing a more precise representation of details in the shadows and bright areas of the image. As a result, the LG UR781 TV performs well in everyday use, offering solid colour quality and clear, well-balanced images in SDR mode.

However, the situation is less favourable for HDR content. The LG UR781 TV does not support a wide colour gamut, which limits the depth and richness of colours that HDR can provide. The EOTF curve deviates from the ideal, leading to excessive highlighting of details in the bright areas of the image. Unfortunately, this approach results in significant colour reproduction errors, as confirmed by tests on the Colour Checker. Additionally, the low brightness level of the panel further negatively impacts HDR image quality, causing the effects of dynamic range to not be fully realised and colours to appear washed out.

Despite some shortcomings in HDR mode, the TV has significantly improved after calibration, especially in SDR content. The enhancement of white balance and gamma has notably increased image quality, providing a more natural and cohesive colour reproduction. Compared to its pre-calibration state, the difference is clear, and the LG UR781 TV now offers better performance in everyday use, particularly in standard dynamic range.

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.

Let's now address the function of smoothing tonal transitions and its impact on overall picture quality. As illustrated by the photo on the left, this function performs exceptionally mediocre; we chose the "low" level, which does not enhance quality but also does not blur the film grain. There is a possibility to increase the strength of this function, which could soften this gradation, but one must consider that the image will be too softened in certain scenes.

On the other hand, regarding image scaling, the television does not perform outstandingly, which may be particularly noticeable with lower resolution content. The LG UR781 television applies a slight, artificial sharpening boost, making the image appear sharper; however, this mainly results from the application of artificial contours. For some users, this may be an advantage, as they prefer more vivid, pronounced details. However, this is a subjective matter—such an effect may not appeal to everyone, especially if they desire a more natural appearance of the image.

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.

The LG UR781 TV offers quite decent smoothness for movies, thanks to the "True Motion" option, which allows users to adjust the motion smoothing level on a scale from 0 to 10. Users can choose whether they want to maintain a more traditional, cinematic effect with a slight stutter (lower settings) or prefer a smoother image with a theatrical quality, which, although slightly deviating from the cinematic standard, may appeal to many.

In dynamic sports content and gaming, the LG UR781 TV performs worse. The TV has a 60Hz panel, which limits its interpolation capabilities to these values; therefore, smoothness can be improved in films, but motion blur cannot be reduced. Additionally, the lack of support for 120 Hz and BFI (Black Frame Insertion) technology means that fast-moving objects become blurred, and the panel's response time is too slow, negatively affecting clarity in fast scenes. As a result, the TV may not meet the expectations of gamers and sports fans who are counting on a smooth, clear image without motion blur.

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.

When playing on a console, the LG UR781 TV offers several significant features that can affect the gaming experience, but it also has some limitations. On the plus side, it includes ALLM (Auto Low Latency Mode), which automatically optimises the picture settings by switching the LG UR781 TV to low latency mode, which is beneficial for gamers. The TV also supports correct implementation of HGiG, meaning HDR games look as intended by the creators.

Unfortunately, it lacks support for Variable Refresh Rate (VRR), which can result in worse gameplay smoothness, especially in more dynamic games. It also does not support Dolby Vision mode for gaming, which limits HDR picture quality in games using this format. The TV has a 60Hz panel, so it does not support higher frequencies at other resolutions, such as 1080p@120Hz, 1440p@120Hz, or 4K@120Hz, which is a significant downside for gamers expecting smoother gameplay at higher resolutions. There is also no support for G-Sync technology, which limits image synchronisation in games.

On the positive side, the presence of a Game Bar feature allows for quick access to settings for gamers and makes it easier to adjust picture parameters during gameplay.

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".
