Sharp GP6765 vs Hisense S7NQ CanvasTV

In film mode, the television Sharp GP6765 reaches a brightness level of 300 nits, unfortunately, this is quite an average result. Such brightness is closer to the standard SDR image than to what should be offered by a full HDR experience. As a result, the television is unable to convey the full depth and dynamics of the image that one could expect from a good HDR mode. The visual effects that appear vivid and detailed in other models may seem muted here, and high-contrast scenes will not look as impressive. However, it is worth noting that when comparing this result with televisions in this budget, it is a decent score. A positive feature is the fact that the television supports a wide colour gamut of DCI-P3 at 92.5% thanks to the implementation of quantum dots (Quantum Dot/QLED). This is quite a respectable result, especially in this price category. As a result, the colours are vibrant and more saturated, which certainly affects the picture quality, although it does not fully salvage the HDR experience due to limited brightness.

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.

Sharp GP6765 was launched in movie mode, which is the best setting for colour reproduction. Unfortunately, despite this, the quality still falls short of ideal standards. Starting with white balance, in SDR mode, the graph shows significant increases in the case of the red colour. This effect can make the image appear slightly yellowed, leading to distortion of natural skin tones. As a result, viewers may notice that some scenes seem unnatural, and colours lose their authenticity. In HDR mode, the situation changes dramatically – the dominant colour becomes blue. Such a strong shift towards blue also negatively affects the colour balance of the image, which can lead to loss of detail in cool tones. Viewers may feel that the image is somewhat cold and out of balance, which further emphasises the fact that the television does not achieve optimal colour reproduction. Tests carried out using the Colour Checker tool confirm these shifts in several tested samples.

As for contrast, in HD mode, the range shows a significant jump at the beginning of the graph, but then remains close to the reference line at 2.4. This means that in most scenes, the television is able to deliver a satisfactory level of contrast. For the viewer, this translates into better perception of details in shadows and greater depth of the image, which affects their overall experience when watching films and TV programmes. In HDR mode, however, the EOTF curve displays large fluctuations both at the beginning and at the end of the graph. Such fluctuations can lead to inconsistencies in the reproduction of details in bright and dark areas of the image. For the viewer, this means that in scenes with intense light, such as explosions or dynamic actions, crucial details may disappear, and the image can appear blurred. Conversely, in darker parts of the image, the lack of clear differences in shades can cause details to merge into a uniform blob, significantly reducing the quality of viewing. Although movie mode offers the best factory settings in the GP6765, both in terms of colour reproduction and contrast, it still has significant issues.

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.

After calibration, in film mode, the white balance on the Sharp GP6765 television for SDR content shows a significant improvement. All lines in the graph approach the reference line. Although they are not perfectly straight, the results achieved are satisfactory, considering the price range of this model. Such an improvement in white balance translates to a more natural and accurate colour reproduction, positively affecting the overall visual experience and immersion in the films being watched. As for the gamut, the initial spike on the graph was not removed; however, after this error, the rest of the lines represent the expected effect much better, making the picture more consistent and enjoyable to perceive.

In the case of HDR content, the white balance performs somewhat worse compared to SDR content, but it is still significantly better than before calibration. The improvement in white balance in HDR contributes to greater colour consistency, making watching films more enjoyable, even though there may be some shortcomings. Speaking of contrast, it is difficult to mention a significant improvement here. Our specialists noted that the lack of control over the dynamic tone mapping settings hindered achieving a significant improvement in EOTF, leading to uneven brightness representation.

Despite some shortcomings related to the lack of settings options for dynamic tone mapping, the Sharp GP6765 television has gained a new identity after proper calibration. The enhanced white balance and better colour reproduction in SDR mode make the image more natural and pleasing to the eye. Although there are still areas that require improvement, especially in HDR content, the television offers a satisfying visual experience, making it an interesting choice within its price range.

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.

On the Sharp GP6765 television, the "10-bit colour reproduction" feature performs well in the tested scene with light bulbs. Setting this option to "medium" yields satisfactory results, as there are no issues with grain smoothing or blurring of significant elements of the image. Setting it to "low" also produces positive results, offering a clear picture without negatively impacting the details. Such smoothing options for tonal transitions contribute to an improvement in visual quality, enabling more natural colour transitions.

In the context of image scaling, the Sharp GP6765 television has its strengths, such as the absence of overscan when displaying test material. This allows viewers to enjoy a full picture without losing any detail from the edges. However, in the tested scene with the model, there are some shortcomings. The branches and trousers do not look their best. Their outlines appear slightly jagged, suggesting that effective edge smoothing techniques have not been applied. This causes some details to look slightly distorted, which can affect the overall visual experience.

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.

When it comes to trailing and motion smoothness, the Sharp GP6765 television performs rather mediocrely. It is equipped with a 60 Hz refresh rate panel, which suffices in the context of films. The television has a motion enhancement feature called "Motion Improvement". Thanks to this feature, we can control the fluidity of motion, allowing us to choose whether the image should appear with film-like frames or be smoother - theatrical. This enhancer should satisfy most users who focus on film content. However, when it comes to sports or gaming, Sharp does not perform at its best. In the tested scene with the UFO alien, there is noticeable blurriness, suggesting that the low response time of the panel negatively impacts the sharpness of moving objects. Such effects can be particularly frustrating during dynamic sequences where quick movements are common. For those who prefer watching sports or intense video games, the limitations in motion smoothness may be discouraging, making the Sharp GP6765 not necessarily the ideal choice in this category.

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.

The functionality of Sharp's GP6765 for gamers leaves much to be desired. Although this model is equipped with HDMI 2.1 ports, which in theory should offer a range of modern conveniences, in practice the situation is far worse. The only feature that truly utilises the capabilities of this standard is Auto Low Latency Mode (ALLM). Unfortunately, the lack of support for key features such as Variable Refresh Rate (VRR) or HDR Gaming Interest Group (HGIG) makes this television a less attractive choice for gamers. VRR is crucial for eliminating issues with tearing and stuttering, which is particularly important in dynamic games where image fluidity is key. Meanwhile, HGIG allows for optimal HDR reproduction, enhancing immersion and visual quality. While it might seem that the implementation of Dolby Vision would bring significant benefits, it is completely useless for gamers due to the very high input lag in this mode.

One could say that the presence of HDMI 2.1 ports in Sharp GP6765 is a marketing trap that may mislead users into thinking that the HDMI standard automatically entails all its conveniences. Expecting full functionality, which should go hand in hand with HDMI 2.1, could lead to disappointment.

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".
