Sharp FQ8 vs Samsung DU7192 (VA)

Sharp FQ8 can achieve a maximum brightness exceeding 450 nits, which is a satisfactory result. Although it may seem that this value is not impressive, it still places it among the top televisions in this price range. In our opinion, this is also a value from which we will feel the richness of the image and the operation of any metadata, which cannot be said about darker devices. The television supports the advanced HDR format known as Dolby Vision. It is also equipped with DOLBY Vision IQ technology, which stands out for its ability to automatically adjust brightness and image colours based on the lighting conditions in the room. Unfortunately, it has been poorly implemented, resulting in significant inaccuracies such as artificial brightening of the image. Therefore, we do not recommend using this technology in this model. Additionally, the colour gamut coverage is around 94% thanks to the use of quantum dot technology, enabling vibrant and realistic colours. This set of features ensures that the image is not only intense but also full of details.

In the luminance charts, the peak brightness of the television is around 280 nits. Unfortunately, this value is too low to fully enjoy HDR effects, which require significantly higher luminance. In the tested materials, such as The Meg and Gemini Man, the lack of adequate brightness severely limits the magic of HDR, and the details in the brighter parts of the image are not sufficiently highlighted. For users primarily consuming SDR content, this level of quality may be acceptable, but it is definitely not enough when it comes to HDR. Additionally, the coverage of the DCI-P3 colour palette at 82% does not favour presenting HDR content in its full glory. The limited colour gamut makes it difficult for the television to reproduce vibrant and diverse colours, which is crucial for achieving a cinema-like experience.

The colour reproduction test in Sharp FQ8 was conducted in film mode, which out of the box offers the best visual capabilities, providing viewers with a colour experience closest to reality. Nevertheless, it cannot be described as exceptional, as there are still some shortcomings that affect the overall picture quality. Colour reproduction in Sharp FQ8 for HD content demonstrates significant issues with white balance. On the graph, the red line clearly rises, indicating excessive dominance of the red colour. This is also confirmed by tests using colour samples, which show that many colours deviate towards red. For example, in a scene from a film featuring a child, the image is very warm and unnaturally red. Similar difficulties occur with 4K HDR content, where there is also noticeable excessive presence of the red colour. It is worth noting this, especially for those who value faithful colour reproduction.

Regarding contrast for SDR, at the beginning of the gamma graph there is a strange characteristic, suggesting issues with reproduction. Subsequently, the entire line is below the reference line, indicating that the television does not achieve appropriate brightness and contrast values in standard content. Meanwhile, the EOTF curve for 4K HDR shows significant discrepancies. Such fluctuations indicate difficulties in maintaining consistent brightness reproduction, leading to unpleasant visual effects when viewing HDR content.

The best factory mode we relied on during testing turned out to be "Filmmaker". Although this mode is the closest to the creators' intent for films, it is not without certain imperfections. The white balance chart in both SDR and HDR clearly shows a dominance of red, resulting in significant yellowing, particularly noticeable in whites and on actors' faces. In HDR mode, there is also a slight dominance of green, which, however, does not have as much impact on the perception of the image. The gamma, which is responsible for brightness in SDR materials, performed quite well, but with one serious caveat. In the darkest parts of the image, it was too low, causing excessive brightness in those scenes, depriving the film of drama and contrast. For HDR, the white balance remains at a similar level; however, the EOTF curve chart draws attention. At the beginning, the curve clearly bulges, leading to a strong brightness in the darkest scenes. Then the result suddenly drops below the reference line, resulting in an overly dark image and a loss of dynamics in the brighter parts.

In summary, the "Filmmaker" mode, despite its advantages, requires refinement – especially regarding white balance and proper management of brightness in the darkest and brightest parts of the image. In its current form, it may be acceptable for less demanding users, but for viewers expecting precise image reproduction, it may leave much to be desired.

After calibration, for SDR content, the white balance on Sharp FQ8 has been significantly improved, and all lines have come much closer to the reference line. Of course, they are not perfectly straight, but it's hard to expect better results from a television in this price range; they are really very good. Improving white balance means that colours are more natural and accurately reproduced, which positively impacts the overall visual experience. In terms of gamma, the strange jump at the beginning of the graph has not been eliminated, however, after this error, the entire line is much closer to the expected effect.

For HDR content, the white balance is somewhat worse compared to SDR content, but it is still significantly better than before calibration. It is worth noting that the improvement in white balance in HDR contributes to a more consistent and pleasant perception of colours, even though there may still be shortcomings. Regarding the EOTF graph and the associated contrast, our specialists noted that the lack of control over dynamic tone mapping settings hindered the achievement of significant improvement in this area. This leads to uneven brightness representation.

Despite the shortcomings resulting from the inability to adjust settings for dynamic tone mapping, Sharp FQ8 has gained a new perspective after proper calibrations. The improved white balance and better colour reproduction in SDR mode make the image more natural and pleasing to the eye. Although there are still areas for improvement, especially in HDR content, the television offers satisfying visual experiences, making it a noteworthy choice in its price range.

Even for its lower models, Samsung offers advanced image calibration tools, which allow for significant improvement of the factory settings. We undertook this task, and the results turned out to be more than satisfying. The white balance, which previously exhibited a strong yellowish tint in both SDR and HDR, was significantly improved. Although slight deviations from the norm can be noticed, the overall effect is much cleaner and more natural than before calibration. As a result, whites and skin tones look much better. We also managed to properly shape the gamma in SDR materials, which allows for achieving the maximum contrast that this television can offer. The EOTF curve, responsible for HDR materials, was also improved – the image is no longer brightened or darkened as drastically as it was before calibration. Despite these successes, HDR materials still struggle with high deltaE error values. The main reason lies in the limited brightness of the television, which does not allow for a complete representation of the dynamics of HDR content. Nevertheless, after calibration, the image is clearly better and more aligned with the creators' intentions. For users seeking the best possible quality in this class of equipment, calibration is definitely recommended.

The "10-bit colour reproduction" feature in Sharp FQ8 performs reasonably well, as we can see in the image with bulbs that shows slight connections between grey shades. For the best results, it is recommended to set medium, which does not reveal issues with grain smoothing or blurring of essential image elements. Alternatively, the "low" setting also proves to be safer and delivers positive effects.

As for upscaling, the Sharp FQ8 television plays back video without overscan, allowing for full use of the screen. The branches shown in the image are noticeably jagged, while the edges of the trousers appear without clear jaggedness, positively affecting the overall image quality. Additionally, the television offers an AI Super Resolution feature, which artificially sharpens jagged elements, enhancing their clarity.

The tonal smoothing function operates in two modes – "off" and "auto". Turning it off causes gradation issues, while the "auto" mode ensures smooth transitions, but at the cost of grain and detail, which are often blurred. Due to these limitations, we do not recommend using this feature, as confirmed by our tests conducted with it turned off.

Scaling of lower resolution materials in this model is not impressive. Details are blurred, and the edges of objects may contain artifacts. This limitation makes the television perform better with higher resolution content.

Sharp FQ8 is equipped with a 120 Hz panel, with the possibility of achieving 144 Hz on PC, which in theory should translate to smooth motion rendering. The television offers functions for improving the smoothness of films and reducing motion blur, which is important for more dynamic content. However, the lack of Black Frame Insertion (BFI) technology combined with an average response time of the panel does not yield positive results. The effect is slight blurring of moving objects, and this may be more noticeable when watching sports or during intense gaming.

Although the Samsung DU7192 is the lowest model in the manufacturer's range, it is equipped with motion smoothing technology. While the functionality of this solution is significantly limited compared to more expensive models, its presence alone distinguishes the television amidst competitors in this price bracket. The TV supports a maximum refresh rate of 60 Hz, which is sufficient for comfortable viewing of films and series, but may be inadequate for dynamic content such as sports. In the motion smoothing menu, we can find, among other things, the "Judder Reduction" feature. Unfortunately, its performance leaves much to be desired – regardless of the setting, the picture exhibits the characteristic stutter known from materials recorded at 24 frames per second, making this feature practically ineffective.

Sharp FQ8 offers several significant features dedicated to gamers that can enhance the gameplay experience. First and foremost, the television is equipped with HDMI 2.1, which comes with certain advantages. ALLM (Auto Low Latency Mode) switches the television to a mode with minimal input lag when a gaming device is detected. VRR (Variable Refresh Rate) reduces screen stutter by adjusting the refresh rate to the number of frames generated by the console or computer, providing smoother experiences, especially in dynamic games. Additionally, the television supports G-Sync technology, which synchronises the image with the graphics card, eliminating stuttering and screen tearing. Despite these advantages, FQ8 also has some limitations. The lack of support for HGiG (HDR Gaming Interest Group) means that the television does not optimise dynamic range for HDR games. The Dolby Vision mode, although theoretically offering better image quality in games supporting this format, suffers from very high input lag.

Samsung DU7192 is equipped with HDMI 2.0 ports, which is expected in this price range. This limitation means there is no support for the full capabilities of the latest generation consoles, such as VRR technologies. The television only offers a basic feature for gamers – automatic switching to low latency mode (ALLM), and support for basic HDR for games in the HGiG standard. HGiG allows for the display of HDR content in games according to manufacturers' guidelines; however, the limited brightness of the television does not allow for full enjoyment of the effects that this standard offers. Unfortunately, there is a lack of conveniences such as GameBar, which is increasingly found even in cheaper models and greatly facilitates quick adjustment of settings for games. The presence of this feature could significantly enhance user comfort, especially for those who frequently change display modes.
