Sharp GP6765 vs Sony Bravia 8 (XR80)

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 Sony Bravia 8 performs commendably in terms of HDR brightness, reaching a peak of 880 nits. This level is sufficient to render lighting effects effectively in most scenes. In tested clips from Life of Pi and Sicario 2, the television demonstrated vibrant, detailed imagery that captured the atmosphere of these films beautifully.

However, challenges arise in scenes with consistently high brightness, such as in The Meg, where the display's limitations become apparent. In these situations, OLED technology can struggle, with brightness levels dropping to around 450 nits, which can be less satisfying when intense illumination is needed throughout a scene. Despite this, the Sony Bravia 8 remains a strong contender, offering excellent DCI-P3 colour gamut coverage and 74% BT.2020 coverage. These attributes result in rich, accurate colours and fine details, enhancing HDR content and providing an enjoyable viewing experience.

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.

The best factory mode on the Sony Bravia 8 television is IMAX Enhanced, offering the most cinematic experience, though it isn't perfectly calibrated. The TV attempts to replicate cinematic settings as accurately as possible, but some issues are evident. Starting with white balance, both for SDR and 4K content, there is a noticeable blue dominance, making the image appear too cold and lacking in natural warmth. Colour Checker tests reveal a shift towards cooler tones, affecting colour accuracy and making the image feel less lifelike.

Regarding brightness and contrast, the gamma shows a significant drop towards the end of the spectrum, meaning dark details may become too shadowed, and bright areas too intense, causing a loss of subtlety and detail. This is particularly noticeable in the sky, as seen in the comparison image. Additionally, the EOTF curve is considerably above the reference value, making bright elements overly intense. As a result, users may experience an unnatural image, with bright parts losing detail and negatively impacting the overall viewing quality.

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.

The calibration process of the Sony Bravia 8 television resulted in significant improvements in image quality. The white balance was notably enhanced for both SDR and 4K HDR content, with minimal errors in the middle section of the graph. Gamma calibration was one of the biggest improvements, eliminating previous dips that had impacted brightness stability and the reproduction of detail in dark areas. The EOTF curve was also corrected, making bright elements appear more natural and improving the overall tonal balance.

However, the most attention should be given to colour reproduction, where some issues persist despite calibration. Sony has omitted the CMS system in this model, which would allow for more precise colour control. As a result, the Colour Checker test for 4K content still reveals significant colour inaccuracies. Despite these limitations, calibration is still recommended, as the improvements in brightness and contrast are noticeable and greatly enhance the overall image quality.

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.

The fluidity of tonal transitions in lower-quality materials on the Bravia 8 is lacking. Unfortunately, the gentle gradation function, which was available in previous models, is missing, which is a significant drawback. The digital noise reduction feature can improve tonal transitions, but it often removes fine details, such as clouds in scenes from The Martian, which may not be to everyone's taste. On the other hand, the digital processing in the Sony XR80 is quite effective. In test scenes, it performed well without noticeable flaws, and the branches in the background remained smooth without jagged edges. This indicates that the Bravia 8 is capable of handling complex low-resolution image details with relative ease.

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.

The Sony Bravia 8 offers a maximum refresh rate of 120 Hz, ensuring smooth viewing of dynamic content such as sports and games, with sharp and fluid motion. For more demanding users, the Sony XR80 features an advanced motion smoothing system, divided into three settings: Smoothness (Film), Smoothness (Camera), and Clarity. The first two settings adjust the level of blur and smoothness, while the Clarity setting will be discussed in more detail below. Each of these parameters can be customised to suit individual preferences, allowing users to fine-tune the settings for the optimal viewing experience.

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.

The Sony Bravia 8 has greatly improved its compatibility with consoles compared to earlier models. It supports variable refresh rate (VRR), which eliminates screen tearing and can sync with graphics cards for smooth visuals. The Auto Low Latency Mode (ALLM) reduces input lag, a crucial feature for fast-paced games. Additionally, Dolby Vision with low latency enhances HDR effects, offering stunning visuals during gameplay.

The Sony XR80 also includes a Game Bar, which provides quick access to settings and monitoring tools during gaming. A notable feature is the option to enable a virtual crosshair on the screen, giving players a potential advantage in shooter games.

However, there are some drawbacks. The TV lacks support for 1440p@120Hz resolution, which would benefit users with less powerful graphics cards. Furthermore, the Sony XR80 has only two HDMI 2.1 ports, one of which is typically used for connecting an audio system via eARC, limiting the number of available ports for next-gen consoles.
