Sharp GP6765 vs Samsung DU8002 (IPS)

In movie mode, the Sharp GP6765 reaches a brightness of 300 nits, which is relatively average. This level of brightness is more suited to standard SDR content than to the full HDR experience. As a result, the TV struggles to deliver the depth and dynamics typically expected from a good HDR mode. Visual effects that might appear sharp and detailed on other models could seem more subdued here, and high-contrast scenes won't be as striking. However, compared to other models in this price range, this is still a decent performance. A positive feature is the TV's support for a wide DCI-P3 colour gamut, covering 92.5%, thanks to the inclusion of quantum dots (Quantum Dot/QLED). This offers a solid improvement, particularly in this price bracket, resulting in vibrant and more saturated colours, although the limited brightness still prevents a fully immersive HDR experience.

The HDR effect in the DU8002 television leaves much to be desired. A brightness level of 300 nits is not able to provide a true high dynamic range experience, making the content viewed resemble more of a standard SDR than impressive HDR. Scenes that should dazzle with brightness and detail appear muted and lacking in depth. Nevertheless, the television deserves praise for its high coverage of the DCI-P3 color palette at 92%. As a result, the colors are vivid and saturated, which may satisfy viewers who prefer rich hues, even if the HDR effect does not fully meet expectations.

The Sharp GP6765 was launched in movie mode, which offers the best settings for colour reproduction. However, despite this, the quality remains far from ideal. In SDR mode, the white balance graph shows significant increases in the red colour, making the image appear somewhat yellowish and distorting natural skin tones. This results in some scenes looking unnatural, and colours losing their authenticity. In HDR mode, the issue worsens as blue becomes the dominant colour, which negatively affects the colour balance and causes a loss of detail in cool tones. As a result, the image can appear cold and unbalanced, highlighting the TV's inability to achieve optimal colour reproduction. Tests with the Colour Checker tool confirm these shifts across several samples.

In terms of contrast, the HD mode shows a significant jump at the start of the graph, but it remains close to the reference line at 2.4. This means that in most scenes, the TV delivers a satisfactory level of contrast, enhancing details in shadows and adding depth to the image. However, in HDR mode, the EOTF curve fluctuates significantly at both ends of the graph, leading to inconsistencies in bright and dark areas of the image. In scenes with intense light, such as explosions or dynamic actions, key details may be lost, and the image may appear blurry. Similarly, in darker scenes, the lack of clear differences in shades may cause details to merge into a uniform spot, reducing overall quality. While movie mode offers the best factory settings for the GP6765, there are still significant issues with colour reproduction and contrast.

DU8002 offers a Filmmaker mode, which is supposed to provide authentic image reproduction in line with the creators' intentions. Unfortunately, despite the promising name, the results are far from ideal. The white balance in this mode shows significant drops in blue color, leading to a noticeable yellowing of the image, which can be seen, for example, in our comparison photo. Colour Checker tests confirm these errors. As for brightness, the gamma characteristic is too low compared to the reference line of 2.4, resulting in excessive screen brightness. A similar problem occurs with 4K content – the EOTF responsible for brightness in 4K material shows significant increases above the reference line, leading to excessively bright small light elements. As a result, the Filmmaker mode in DU8002 does not meet expectations and instead of offering high quality, presents an image full of tonal and color inaccuracies.

After calibration, the Sharp GP6765 television shows marked improvement in film mode, particularly in SDR content. The white balance now closely aligns with the reference line, offering more natural and true-to-life colour reproduction. While not perfectly straight, the results are still satisfactory for the price range, significantly enhancing the overall visual experience and immersion in movies. The colour gamut shows some improvement, with the initial jump in the graph persisting but being less noticeable, leading to a more consistent and enjoyable image.

For HDR content, while the white balance performs somewhat worse than in SDR, it is still a notable improvement compared to pre-calibration. The calibration ensures better colour consistency, though some shortcomings remain. As for contrast, no major gains were observed. The lack of control over dynamic tone mapping prevented significant improvement in EOTF, resulting in uneven brightness reproduction.

Despite some limitations, particularly in HDR content and dynamic tone mapping, the Sharp GP6765 reveals a more polished performance after calibration. The improved white balance and colour reproduction in SDR make it more visually appealing. While further refinement is needed, it still provides a satisfying visual experience, making it a strong contender in its price category.

Samsung is one of those companies that offers advanced tools for improving image quality in its televisions, including a 20-point white balance adjustment. Even with the budget model DU8002, with the right adjustments, surprisingly good results can be achieved. The white balance, especially for HD content, performs really well - tests on the Colour Checker palette confirm accuracy at the level of 2–1.5, which demonstrates the significant capabilities of this television in color reproduction. In 4K content, although not as perfect as in lower quality material, the overall picture looks much better.

The gamma brightness has also been heavily adjusted, ensuring that the image is not overly brightened and looks more natural. What about the EOTF curve? At first glance, it seems fine, but upon closer inspection, especially in film tests, it becomes apparent that the television struggles due to its low contrast panel. The EOTF drops below the reference line. Nevertheless, the DU8002 is an example of a budget model where investing in calibration is worthwhile. Although structural flaws, such as the type of backlighting, cannot be completely eliminated, color accuracy is surprisingly good, especially considering its price.

The Sharp GP6765 television delivers solid performance with its "10-bit colour reproduction" feature, particularly in the tested scene featuring light bulbs. Setting this option to "medium" provides satisfactory results, with no issues related to grain smoothing or the blurring of important image elements. Even the "low" setting performs well, delivering a clear image without compromising detail. These transition smoothing options enhance visual quality by providing more natural colour transitions.

In terms of image scaling, the Sharp GP6765 shows strengths, such as the absence of overscan when displaying test material. This ensures viewers can enjoy the full image without losing edge details. However, some weaknesses were noted in a tested scene featuring a model. Elements such as branches or trousers appear slightly jagged, indicating a lack of effective edge-smoothing techniques. This can cause certain details to look distorted, impacting the overall viewing experience.

Smoothing tonal transitions on the DU8002 television leaves mixed feelings. Although the menu offers an option for smoothing tonal transitions, in practice it yields no results and can even generate unwanted side effects.

Nevertheless, the television handles upscaling, or digital image processing, excellently. The test chart featuring a model looked really good – the image is not overly jagged, and the overall presentation is decent and pleasing to the eye. This is definitely good news for those planning to watch traditional television on this model.

When it comes to motion blur and movement fluidity, the Sharp GP6765 TV offers rather average performance. Equipped with a 60 Hz panel, it handles movies adequately. The TV includes a motion smoother called "Motion Enhancement," which allows users to control motion fluidity, enabling a choice between visible film frame interpolation or a smoother, more theatrical appearance. This feature should meet the needs of most users focused on movie viewing.

However, the TV's performance falls short in sports or gaming. In the tested UFO alien scene, noticeable blurriness indicates that the panel's low response time negatively impacts the sharpness of moving objects. This issue becomes particularly evident during dynamic sequences, where rapid movements are frequent. For viewers who enjoy sports or fast-paced video games, these limitations in motion handling can be off-putting, making the Sharp GP6765 less suitable for such content.

DU8002 with a 60 Hz panel is a television that performs better for watching movies than for intense gaming. The motion smoothing feature acts as a fluidizer, smoothing out motion and giving scenes a more fluid appearance, which is useful for movie screenings. In the context of gaming, this model will rather be suitable only for occasional entertainment.

The gaming functionality of the Sharp GP6765 leaves much to be desired. Although this model includes HDMI 2.1 ports, which theoretically promise modern features, the reality is far less impressive. The only feature that takes advantage of this standard is Auto Low Latency Mode (ALLM). Unfortunately, the absence of key functionalities such as Variable Refresh Rate (VRR) and HDR Gaming Interest Group (HGIG) significantly limits its appeal to gamers. VRR is crucial for eliminating screen tearing and stuttering, particularly in dynamic games where fluidity is essential. Similarly, HGIG ensures optimal HDR mapping, enhancing visual quality and immersion. While Dolby Vision might seem like a benefit, it proves useless for gaming due to the very high input lag in this mode.

The inclusion of HDMI 2.1 ports in the Sharp GP6765 feels like a marketing ploy, potentially misleading users into believing that the standard automatically provides all its associated benefits. Gamers expecting full functionality from HDMI 2.1 are likely to be disappointed.

DU8002 is a television that will mainly serve as equipment for casual gamers. The 60 Hz panel does not provide the highest motion fluidity, so in dynamic games there may be a lack of that extra smoothness of the image. On the positive side, it features ALLM and HGiG functions, which automatically adjust image settings for HDR games, enhancing the gaming experience. Unfortunately, the television is equipped only with HDMI 2.0 ports, so we have to forget about more advanced features like VRR or support for 4K at 120 Hz. When choosing this equipment, we will have to make do if we expect a full set of gaming features.
