Sharp FQ8 vs TCL C655 Pro

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 HDR effect quality category, the television TCL 655 PRO demonstrates decent capabilities, achieving a peak brightness of 550 nits. This allows for enjoyment of the HDR effects, which is particularly evident in scenes such as the first from the film Life of Pi or the last frame from The Meg. Nevertheless, the limited number of dimming zones causes some issues. While in bright scenes the television performs better than its lower model, in more demanding scenes, such as the second and fourth scenes from Sicario 2, it struggles. The dimming algorithm aims to achieve deep blacks, but at the cost of brightness – resulting in a drop in brightness of even half during those moments. In these more challenging scenes with small elements, it is hard to find any praise, and the HDR effect resembles more of an SDR. Regardless, the colour gamut coverage deserves commendation, which, like in the version without the PRO suffix, is at a very good level.

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.

Each of our television tests is conducted in film mode, which usually offers the best colour reproduction. Nonetheless, even this mode is not free from issues, as we noted in the model TCL 655 PRO.

In the case of HD content, the white balance distinctly shifts towards red, and this effect becomes particularly noticeable in a scene from Star Wars, where the white elements of the scenery take on a pink hue. For 4K HDR material, the situation is better, but there is a noticeable tendency to excessively emphasise the colour blue. As a result, the picture may appear artificially sharp, which proves to be uncomfortable for the eye over a longer period. The brightness characteristics also leave much to be desired. The Gamma graph indicates serious difficulties with excessive brightening, causing the overall presentation to appear washed out. Additionally, the EOTF curve reveals significant problems with reproducing very small elements – they are overly dimmed, as we detailed in the paragraph concerning HDR effects.

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.

After calibrating the television TCL 655 PRO, a noticeable improvement in white balance is evident, where the tendency for the screen to have an excessive pink hue has been completely eliminated, which was previously visible in the factory mode. The image has taken on more natural tones, especially in white and light elements, positively affecting the overall perception of the picture. Regarding brightness characteristics, the Gamma chart has also improved – the screen is no longer overly bright, which previously made the image appear washed out. However, there are still some issues with the EOTF curve, which are difficult to eliminate due to the design of the television and its limited number of backlight zones. These limitations prevent achieving perfect results in this regard. Nevertheless, despite this minor flaw, the overall effect after calibration is truly outstanding, providing high picture quality and very good colour reproduction.

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 TCL 655 PRO television performs quite well with tonal transitions in lower quality materials. The "Gradual Smoothing" function at a low setting effectively smooths out tonal transitions, but this comes at the expense of losing some important details, such as the texture of objects. One positive aspect is that it does not negatively affect film grain, which helps maintain the natural appearance of the image.

In the context of digital processing, the television adds artificial sharpness. This may appeal to users who prefer a more vivid image. However, those who like a softer, subtler look may find this a drawback. Additionally, a downside is the cropping of the image due to overscan, which limits the field of view and trims the edges of the frame. This can be problematic in certain scenes - for example, news tickers.

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.

The TCL C655 PRO television is equipped with a 4K panel with a refresh rate of 60 Hz, making it best suited for watching films. Additionally, the "Flicker Reduction" feature allows users to adjust the smoothness of the image, giving them the choice between a smoother motion and a cinematic, frame-by-frame effect. Moreover, the television performs well with lower resolution materials, such as Full HD and 2K, offering a refresh rate of 120 Hz, which will certainly appeal to gamers who can enjoy a smoother picture at the expense of lower resolution.

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.

The TCL C655 PRO television offers an almost perfect set of features for gamers, supporting all the key technologies that significantly enhance the gaming experience. The ALLM feature automatically switches the television to low latency mode, resulting in improved responsiveness and minimal signal delay – particularly important in dynamic titles. VRR synchronises the screen refresh rate with the number of frames generated by the console, eliminating screen tearing and thus guaranteeing smoother gameplay.

Support for Dolby Vision in gaming mode allows for more detailed colour and contrast reproduction in games that support this format, while the Game Bar provides quick access to essential settings such as response time and latency level. Unfortunately, the model does not support 4K resolution at 120 Hz, which may disappoint the most demanding gamers. However, for those willing to forgo 4K, support for Full HD and 2K at 120 Hz delivers exceptionally smooth visuals, presenting an attractive alternative for enthusiasts of higher refresh rates.
