Sharp GP6765 vs Samsung Q7F

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.

Unfortunately, the Samsung Q7F is not one of the bright televisions, which directly impacts the quality of HDR films. The peak brightness of the panel is only around 250 nits, which is definitely insufficient for claiming a true cinematic experience. In practice, the HDR content does not differ significantly from classic SDR, making it difficult to talk about any "wow effect" that usually accompanies us when watching such films. During testing of film scenes, the image simply looked dark, and the brightness almost always hovered around the aforementioned 250 nits. The worst performance came from shots with small, intensely glowing elements – the global dimming technique used reacted very aggressively in those cases, dimming the entire screen to maintain the black effect. However, it is worth noting the presence of a QLED coating that broadens the colour spectrum. For a budget QLED model, the Q7F performs quite decently here: the DCI-P3 colour gamut coverage is around 93%, and BT.2020 reaches 70%. This means that despite the low brightness, the colours can still look quite vivid and attractive.

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.

The reproduction of factory colours in the Samsung Q7F is definitely not one of its strong points. In Filmmaker mode, which theoretically should be closest to neutral, the white balance issue is immediately noticeable. There’s too much red on the screen, while blue is lacking. The effects are very easy to notice – white, instead of being neutral, takes on warm, almost slightly orange tones. In the long run, this makes the entire image appear a bit unnatural, while bright areas of the scene can seem unrealistic. The problems are even more evident in HDR content. The charts show that the TV has significant errors in the Color Checker palette, which results in visible inaccuracies in the real image. In practice, this means that colours are not presented as they should be. The Q7F also heavily manipulates brightness; darker elements are overly boosted, causing them to lose their cinematic feel, while bright parts can be dimmed. This makes the image seem flattened, and contrast, instead of helping to bring out details, only highlights its own limitations. In HDR materials, this is particularly frustrating because every detail matters. In scenes where a subtle play of light and shadow should be felt, the Q7F either overdoes the lighting or, conversely, suppresses elements that should attract the eye. This causes the image to lose its depth, and instead of cinematic realism, we have a rather simplified effect.

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.

After professional calibration, we managed to bring the Q7F to order – at least in terms of SDR content. The image in this mode looks really good: the white balance has been set correctly, the colours appear natural, and the errors in the colour palette have dropped to levels practically invisible to the eye. Gamma behaves exemplary, and the only minor flaw remains a slight lightening of smaller elements, which stems from the lack of local dimming. For everyday watching of television or films in standard quality, the Q7F performs surprisingly well.

It was significantly more challenging to tame HDR content. Despite adjusting the white balance, the television still heavily manipulates brightness, causing scenes to appear unnatural – what was meant to be subtly darker can sometimes be overly bright, and the bright parts of the image can occasionally be dimmed. The final effect is better than in factory settings, but it’s clear that the construction limitations of the Q7F do not allow for fully utilising the potential of HDR materials.

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.

Upscaling and digital image processing in the Q7F is a bit of a rollercoaster. On one hand, we have really nice upscaling – weaker sources look better than you might expect. The image becomes clearer, sharper, and even older films or free-to-air TV hold up well. Samsung has been strong in this area for years, and the Q7F confirms that. On the other hand… things start to get tricky. The TV has a problem with overscan – part of the image is simply cut off, and it doesn't look very elegant. Additionally, we were let down by a feature called "noise reduction," which should improve the smoothness of tonal transitions in weaker materials. In other Samsungs, it works relatively well, but here it practically makes no difference – the banding in gradients is still there. It's a bit of a shame because we expected more from a model that is aimed at users looking for a display for SDR content.

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.

Motion blur and motion fluidity in the Q7F is probably the most budget-friendly aspect of this television. The 60 Hz panel makes the motion blur quite noticeable, especially in dynamic scenes, and it's rather hard to consider this model as equipment designed for watching sports or playing fast-paced games. In tests with the little green man, there was a long trail, similarly, the ball in a football match would leave behind streaks.

On the positive side, the presence of motion smoothing is worth noting. In films, it really makes a difference – especially since most materials are recorded in 24 frames. Here we can decide whether we prefer a more "cinematic" image, with a slight judder typically found in cinema, or a smoother, more “TV-like” one. This actually works quite well and helps improve the viewing comfort for series or movies.

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.

The features for gamers on the Samsung Q7F is a topic that stirs up quite a few mixed emotions. On one hand – no reasonable person was expecting miracles here, after all, it’s a 60 Hz television and it was clear from the get-go that this wouldn’t be equipment to squeeze the maximum from a console or PC. On the other hand, since the manufacturer promised specific solutions in promotional materials, it is only natural that we wanted to see them in practice. At the start, it’s looking pretty good. The automatic game mode (ALLM) works, so there’s no need to manually fiddle with the settings; the console switches the TV to low latency mode by itself. Plus, we have the Game Bar, which looks impressive and allows you to check a few basic parameters without leaving the game. And this is where the good news ends.

The biggest problem with the Q7F is VRR, or rather its absence. Indeed, the appropriate icon appears in the menu, you can even see it in the Game Bar, but throughout the entire test, the function remained dead and could not be activated in any way. Even more disappointing is the matter of HGiG; this option was actually available in the beginning, but after a software update, it disappeared completely, which is just unprofessional. Therefore, the Q7F is only suitable for absolute basics. Sure, you can turn on the console, play calmer titles, and enjoy low input lag, but if someone is counting on more advanced features that the manufacturer promised, they will be disappointed. This is not a television one buys with gaming in mind, and it’s better to be aware of this before purchasing.
