Hisense A6N vs Sharp GP6765

The quality of the HDR effect on A6N unfortunately does not impress. The peak brightness of 250 nits does not allow for spectacular effects, and HDR appears rather dull, resembling more of a regular SDR. This state of affairs will not satisfy more demanding users who wish to enjoy high-quality film materials. Additionally, the coverage of the colour palette is also not very impressive – a DCI-P3 level of 82% is an average result that does not fully allow one to enjoy vibrant colours in HDR materials.

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.

In the category of colour reproduction, the model Hisense A6N in Filmmaker Mode leaves much 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. The problem with white balance is particularly noticeable, both for HD and 4K materials, which is heavily disrupted by the dominance of blue. This results in artificial, cold tones, which can clearly be seen in the comparison photo 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 in maintaining a level of 2.4 – the graph is significantly below the reference value, which leads to excessive image brightness and washed-out blacks. The EOTF curve for 4K materials also indicates brightness issues – at the beginning, there is a significant spike, which results from the television's excessive brightness, negatively impacting image quality. Such image characteristics do not allow one to fully enjoy watching films and require manual correction.

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.

Hisense A6N offers options and tools in its settings to adjust many image parameters that we have utilized. When it comes to white balance, we managed to eliminate the excess blue colour – this effect is clearly visible in the comparison photo below, where the boy in the image seemingly "comes to life". A significant improvement can also be noticed in the gamma brightness characteristics – the television no longer has serious issues with excessively brightening the entire image. Unfortunately, the same cannot be said for 4K content, where the EOTF curve could not be fully corrected due to the exceptionally low brightness of this model. For HDR materials, we apply dynamic tone mapping, which allows for the recovery of many details despite the boosting of mid-tones in the image. For this television, this provides more benefits than drawbacks. The errors that are still visible in the colour palette test and Colour Checker for 4K materials stem from the low colour gamut coverage and are difficult to eliminate due to the characteristics of the television. 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 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.

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

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.

The 60 Hz panel in the Hisense A6N will likely satisfy those who enjoy watching films, as the television offers an "ultra motion smoother," allowing us to adjust the motion smoothness – either more choppy or more fluid, cinematic. When it comes to motion blur, it performs rather average – noticeable blur is evident, especially on dark backgrounds, which is quite a typical feature in this range of televisions.

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.

Hisense A6N is a television that is likely to appeal to casual gamers, primarily due to its 60 Hz panel, which may not satisfy more demanding users. Nevertheless, it offers several features that can enhance the gaming experience. The television supports functions such as ALLM (Auto Low Latency Mode), VRR (Variable Refresh Rate), and Dolby Vision, which allows for better picture quality and smoother motion in games that support these technologies. Moreover, the low input lag ensures quick reactions in gameplay, which is crucial, especially in dynamic productions. With these features, although the television is not an ideal choice for demanding gamers, it provides solid support for those who appreciate comfortable gaming without complicated settings. It is an ideal solution for individuals who want to enjoy gaming without high hardware requirements while also having access to modern technologies that enhance gameplay quality.

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.
