Sharp GP6765 vs Hisense U6NQ

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.

Hisense U6NQ offers a stable HDR effect, which is a rarity in TVs with local dimming. On most streaming platforms, in films and series recorded in 4K, the TV delivers consistent performance – in every tested scene, regardless of difficulty level, brightness is around 450 nits. This is a pleasant surprise, as many models in this class exhibit distinct differences – some scenes are well-lit, while others are heavily dimmed by dimming algorithms. However, the Hisense U6NQ prioritises maintaining higher brightness, which comes at the cost of blacks, as noted in the paragraph about the contrast test.

The HDR effect on the U6NQ is satisfying, offering a noticeable 'punch' of light in bright moments, although it's worth remembering the aforementioned blooming, which can be visible in challenging scenes. In terms of colour, the TV also performs adequately – the coverage of the DCI-P3 colour gamut is 89%, while BT.2020 is 71%. While these are not results that would impress more demanding users, for beginners in the world of high-quality materials, the U6NQ is a solid choice. As such, it presents an interesting option as an 'entry-level' TV for home cinema.

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 U6NQ in Filmmaker mode offers really decent colour reproduction, although it's worth remembering that differences between individual units can be noticeable. The model we tested was pleasantly surprising, especially with HD content in SDR quality. The white balance was correct here, and errors in the range of 3–4 ΔE should be acceptable for the average viewer. The television performed slightly worse in reproducing colours with 4K HDR material. The dominance of blue tones led to unnatural cool shades on the Colour Checker chart, giving the image a "store" character. Combined with issues in brightness characteristics – gamma and EOTF curve caused some parts of the image to be too dark – the Filmmaker mode in this case loses some of its credibility. Although the factory settings of the tested unit deserve praise, particularly in SDR, there were still minor shortcomings that would require adjustments to fully utilise the television's capabilities.

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.

Although the factory settings of the Filmmaker mode on Hisense U6NQ were quite good, we decided to undertake calibration to fully assess the capabilities of this model. Only after such a procedure can one see how the television performs under ideal conditions. In the case of SDR content, which was already at a high level, we managed to further improve the white balance. However, the biggest change came from adjusting the brightness characteristics – gamma was optimised and no longer causes excessive darkening of the image, which improves its naturalness.

For 4K HDR content, calibration also yielded positive results. We eliminated the issue of blue dominance, which resulted in a more balanced and natural image. However, managing brightness in HDR materials remains a more complicated issue. The EOTF curve, although it had problems with image darkening in the 10–30% brightness range under laboratory conditions, reveals other shortcomings in real scenes. The television tends to overly brighten the smallest elements on the screen. As a result, this leads to noticeable halo effects around bright objects. This phenomenon, which we mentioned earlier in the context of contrast and HDR, arises from the technological limitations of the model and is often difficult to eliminate.

In short: although the Filmmaker mode with factory settings performed decently, calibration allowed us to achieve an even better effect – minor adjustments resulted in a more balanced image, particularly in HDR content. For users seeking the highest quality picture, calibration will be a beneficial step.

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.

With high-quality materials like 4K, tonal transitions on U6NQ look really good – colours blend nicely and the image is consistent. Unfortunately, when we switch to lower resolution content, the television doesn’t offer any extra features that could improve this aspect. An example is the test with the light bulb, where it’s clearly visible that the television struggles with reproducing subtle tonal transitions.

On the other hand, digital processing performs quite well. The image looks lively, is pleasantly soft, and free from excessive artifacts. Moreover, thanks to the sharpness settings, it can be tailored to individual preferences – whether towards a softer or sharper image. Overall, while upscaling lower quality materials could be better, the television handles image processing well.

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 U6NQ offers native refresh rates of 60 Hz at a 4K resolution, but the manufacturer has added a feature that allows for an increase in refresh rate to 120 Hz, at the cost of reducing the resolution to Full HD. This is a solution we have previously seen in TCL televisions, such as C655 or C655 PRO. This gives the user the option – higher motion fluidity or full resolution. This makes sense, especially considering that many new generation console games do not achieve full performance in 4K at 120 Hz.

When it comes to movies, the television is equipped with a motion smoother feature, which allows you to adjust the motion characteristics to your own preferences. This enables a more cinematic effect or increases fluidity in dynamic scenes. Overall, Hisense U6NQ offers sensible solutions in terms of motion fluidity that should satisfy both gamers and movie enthusiasts.

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.

Hisense U6NQ gives the option to choose between 4K at 60 Hz and Full HD with 120 Hz refresh rate. This solution may appeal to gamers who want to decide what is more important to them – higher resolution or smoothness. The TV supports features like ALLM and VRR, which help in providing smoother gameplay. A nice addition is the GameBar – an easy-to-use panel that allows quick adjustments to picture settings and checking statistics. We also find the Dolby Vision Game mode here, which operates with low input lag, a big plus for console enthusiasts. Unfortunately, it lacks HGiG, which could further improve HDR quality in games. Nevertheless, the Hisense U6NQ performs quite well as a gaming TV, especially for those who play occasionally and do not require the highest refresh rate in 4K. It is a solid choice for less demanding users.
