Hisense A6N vs Sharp GP6765

The quality of HDR effect on the A6N unfortunately does not impress. A peak brightness of 250 nits does not allow for spectacular effects, and HDR appears rather dull, resembling more of a standard SDR. This situation will not satisfy more demanding users who want to enjoy high-quality film materials. Additionally, the colour gamut coverage is also not very impressive – DCI-P3 at 82% is an average result that does not allow for full enjoyment of vibrant colours in HDR materials.

In movie 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 what full HDR experience should offer. As a result, the television is unable to convey the full depth and dynamism of the picture that one might expect from a good HDR mode. Visual effects that in other models are vivid and detailed may appear muted here, and high-contrast scenes won’t look as impressive. However, it's 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 range. As a result, colours are vibrant and more saturated, which certainly impacts the image quality, although it doesn't fully save the HDR experience due to the limited brightness.

In the category of colour reproduction, the model Hisense A6N in Filmmaker Mode leaves a lot to be desired. Although the name of the mode suggests that we should expect faithful reproduction of cinematic colours, the reality is different – the television has significant issues with image quality. Particularly noticeable is the problem with white balance, for both HD and 4K material, which is heavily skewed by the dominance of blue hues. This results in artificial, cold tones, which is clearly visible in the comparative image below. The Colour Checker test further confirms these errors, which are exacerbated by low colour gamut coverage.

The gamma brightness characteristic shows a serious problem with maintaining a level of 2.4 – the graph is significantly below the reference value, leading to excessive brightness of the image and washed-out blacks. The EOTF curve for 4K materials also indicates brightness issues – at the beginning, there is a notable spike, which results from the television's excessive brightness, negatively affecting image quality. Such an image characteristic does not allow for full enjoyment while watching films and requires manual adjustment.

Sharp GP6765 was launched in movie mode, which is the best setting for colour reproduction. Unfortunately, even so, the quality is still far from ideal. Starting with the white balance, in SDR mode the graph shows significant increases in the red colour. This effect can make the image appear slightly yellowish, 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 impacts the colour balance of the image, which can lead to a loss of detail in cool tones. Viewers may feel that the image is somewhat cold and out of balance, which is further highlighted by the fact that the television does not achieve optimal colour reproduction. Tests conducted using the Colour Checker tool confirm these shifts in several tested samples.

When it comes to 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 means better perception of details in shadows and greater depth of the image, which affects their overall viewing experience of movies and TV shows. In HDR mode, however, the EOTF curve shows large fluctuations both at the beginning and at the end of the graph. Such fluctuations can lead to inconsistencies in detail reproduction 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, essential details may disappear and the image may appear blurry. Conversely, in darker parts of the image, the lack of clear differences in shades can cause details to blend into a uniform patch, which significantly reduces the viewing quality. Although movie mode offers the best factory settings in the GP6765, both in the context of colour reproduction and contrast, significant problems do exist.

Hisense A6N offers options and tools in its settings for adjusting many picture settings that we utilised. When it comes to white balance, we managed to eliminate excess blue – this effect is clearly visible in the comparison image below, where the boy in the picture almost "comes to life." A significant improvement can also be noticed in the gamma brightness characteristic – the television no longer has serious issues with excessively brightening the entire image. Unfortunately, the same cannot be said for 4K materials, where the EOTF curve could not be fully corrected due to the exceptionally low brightness of this model. For HDR content, we use dynamic tone mapping, which allows for the recovery of many details despite the boosting of midtones in the image. For this television, this provides more benefits than drawbacks. The errors that are still visible in the test with the colour palette and Colour Checker for 4K content arise from low colour gamut coverage and are difficult to eliminate due to the television's characteristics. Nevertheless, the tonal quality of the image is significantly better, which is why we recommend calibrating the factory settings, which are far from ideal.

After calibration, in movie mode, the white balance on the Sharp GP6765 TV for SDR content improves significantly. All the lines on the graph come closer to the reference line. Although they are not perfectly straight, the achieved results are satisfying, considering the price range of this model. Such an improvement in white balance translates into a more natural and accurate colour reproduction, positively affecting the overall visual experience and immersion in the films being watched. Regarding the colour gamut, the initial jump on the graph was not removed, however after this error, the rest of the lines represent the expected effect much better, making the image more coherent and pleasant to view.

In the case of HDR content, the white balance performs slightly 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, despite some shortcomings that may occur. Speaking of contrast, it is difficult to claim significant improvement. Our specialists noted that the lack of control over dynamic tone mapping settings prevented achieving significant improvement in EOTF, leading to uneven brightness reproduction.

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

Let's check how A6N handles low-quality materials. When it comes to smoothing tonal transitions, the lack of posterization reduction or smoothing of tonal transitions in low-quality materials, such as television or DVD, may be noticeable for more demanding viewers. As for digital processing, the model is presented correctly, and the branches lack characteristic jaggedness – the image is strongly plastic and soft, which may appeal to those who prefer this kind of image style.

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 key image elements. The “low” setting also delivers positive results, providing a clear image without adversely affecting details. Such smoothing options for tonal transitions contribute to enhanced visual quality, allowing for more natural colour transitions.

In terms 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 image without losing any details from the edges. However, in the tested scene with the model, some shortcomings arise. The branches or trousers do not look their best. Their outlines appear slightly jagged, suggesting that effective edge smoothing techniques were not applied. This can make some details look somewhat distorted, which may affect the overall visual experience.

The 60 Hz panel in the Hisense A6N will satisfy those who enjoy watching movies, as the TV offers an "ultra motion smoother," allowing us to adjust the smoothness of the image – either more choppy or more fluid and cinematic. When it comes to motion blur, it performs rather average – noticeable blur is present, especially on dark backgrounds, which is quite typical for this range of TVs.

When it comes to blur and motion fluidity, the Sharp GP6765 television performs quite averagely. It is equipped with a 60 Hz panel, which works well for films. The TV features a motion smoothing function called "Motion Enhancement". With this feature, we can control the fluidity of the motion, allowing us to choose whether the image should appear in a cinematic frame or be more fluid - theatrical. This smoothening function should satisfy most users who focus on film content. However, in the case of sports or games, the 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 affects the sharpness of moving objects. Such effects can be particularly frustrating during dynamic sequences where fast movements are common. For those who prefer watching sports or intense video games, the limitations in motion fluidity may be discouraging, making the Sharp GP6765 not necessarily the ideal choice in this category.

Hisense A6N is a television that is likely to appeal to occasional gamers, mainly due to its 60 Hz panel, which may not satisfy more demanding users. Nevertheless, it offers several conveniences that can enhance the gaming experience. The TV supports features such as ALLM (automatic low latency mode), VRR (variable refresh rate), and Dolby Vision, allowing for better picture quality and motion smoothness in games that support these technologies. Furthermore, the low input lag ensures quick reactions in games, which is crucial, especially in dynamic productions. With these features, although the TV is not the ideal choice for demanding gamers, it provides solid support for those who appreciate comfortable gaming without complicated settings. It's a perfect solution for individuals who want to enjoy gaming without high hardware requirements while still accessing modern technologies that enhance gameplay.

The functionality of Sharp's GP6765 for gamers leaves a lot to be desired. Although this model is equipped with HDMI 2.1 ports, which theoretically should offer a range of modern conveniences, in practice the situation is much 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 TV a less appealing choice for gamers. VRR is essential for eliminating issues with tearing and stuttering, which is particularly important in dynamic games where smoothness of image is crucial. Meanwhile, HGIG allows for optimal HDR reproduction, increasing immersion and visual quality. Although it might seem that the implementation of Dolby Vision will bring significant benefits, for gamers it is completely useless 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 can mislead users into thinking that the HDMI standard automatically entails all its conveniences. Expecting full functionality that should accompany HDMI 2.1 may lead to disappointment.
