Sharp FQ8 vs Panasonic Z85A

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.

The Panasonic Z85A is an OLED television, so one can immediately expect great effects in films. And indeed – our tests have shown that the WOLED panel can achieve around 800 nits of peak brightness in optimal conditions. This is a solid result that performs well in most demanding HDR scenes, allowing viewers to enjoy a dynamic and detail-rich image. However, like any OLED, the Z85A has its limits. In very bright scenes covering the entire screen – such as the final sequence from the film The Meg – the television reduces brightness to around 400 nits. This is standard behaviour for this technology, so if someone plans to watch films in a brightly sunlit living room, it is worth keeping this in mind. The coverage of the DCI-P3 colour gamut at 98% also deserves high praise. Thanks to this, the television reproduces a wide range of colours that stand out with vibrancy and depth, and details in HDR scenes are sharp and precise. In short – the Panasonic Z85A delivers a solid HDR effect that will satisfy any film enthusiast.

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 Panasonic Z85A offers many picture modes, but the Filmmaker mode definitely stands out from the rest. It is rare for a television to be so well tuned straight out of the box, and the unit we had the opportunity to test really surprised us positively.

However, there were a few minor shortcomings. In the SDR signal, we noticed a slight deficit of red and blue, which resulted in the image having a cooler hue than it should have. This is especially noticeable in the comparative photo. Conversely, in 4K HDR content, the situation was the opposite – an excess of red made the image appear warmer than the creators intended. In terms of brightness characteristics (gamma) and the maintenance of the appropriate EOTF curve, it's hard to find fault. There are slight deviations, but they are so minimal that the average viewer is unlikely to notice them.

It is also worth emphasising that our observations pertain to a specific unit of the television. Two identical models may differ from each other due to natural production variances. Nevertheless, the unit we had in our hands looks really solid and deserves praise. Now it's time for our calibration – we'll see if we can extract even more from this screen!

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.

The Panasonic Z85A offers truly wide possibilities when it comes to image settings, so we enthusiastically set about calibration. Although we mainly focused on correcting the white balance, the final result exceeded our expectations. Both HD and 4K HDR content now display nearly perfect colour reproduction, with minimal errors that are hard to catch with the naked eye. Well-calibrated televisions are a rarity, and we must admit – it is truly gratifying. Although the gamma and EOTF curve did not require drastic adjustments, it was possible to further stabilise their characteristics across the entire brightness range. After calibration, the Panasonic Z85A is a true gem for home cinema enthusiasts. The image is precise, the colours are natural, and every scene looks exactly as the director intended.

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.

Now that we know how the Panasonic Z85A performs with tonal transitions in 4K content, it’s time to take a look at its "Gradation Smoothing" feature. It works, but unfortunately not entirely effectively. Regardless of the chosen value – whether it’s low, medium, or high – we were unable to achieve perfectly smooth tonal transitions in our test sequence. We recommend setting this feature to an intermediate level. Although it may slightly blur fine details, at least the issue of film grain loss does not occur, which for many viewers can be crucial when watching classic productions.

As for image scaling, the television performs quite well. It’s noticeable that the image is slightly sharpened, and slim lines may at times appear a bit jagged. However, this is standard in most TVs, and fortunately, it can be adjusted using the sharpness slider. This gives us complete control – we can achieve a more plastic, blurred image or a clearer one, although it may be more “harsh” and artificially sharp. It all depends on user preference and the type of content we are watching. Overall, the scaling is at a solid level and should satisfy most users who are using lower resolution materials.

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 Panasonic Z85A features a 120 Hz panel, which will certainly please both gamers and sports fans. Admittedly, it is not 144 Hz like some gaming TVs, but in practice, the difference is really hard to notice. In games, the image is stable and clear, and during fast action, there is no sign of any blurring. The same applies to sports – a fast-running footballer or a dynamic car manoeuvre looks smooth and natural. The TV also has the “Intelligent Frame Creation” function, which is a motion smoother. There are two sliders here – one is for reducing blur, and the other is for motion smoothness. With these, you can adjust the image to your own preferences – whether it be more of a cinematic effect with gentle transitions between frames, or a maximally smooth image ideal for watching sports.

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.

Panasonic is mainly associated with home cinema televisions, but the Z85A demonstrates that it can also step into the gaming world with a really strong impact. This hardware can easily be called a gaming beast – it has everything needed for comfortable gameplay.

Although there are only two HDMI 2.1 ports, both operate at full bandwidth, so we can easily connect both a next-gen console and a gaming PC. All key features are supported: ALLM automatically switches the television to game mode, VRR ensures smooth images without stuttering or tearing, and with correctly implemented HGIG and Dolby Vision, HDR games look really good – colours are vivid, details are sharp, and dark scenes are clear. We also find a Game Bar in the form of a clear, circular menu. It may not look as impressive as the competition's, but it is intuitive and contains all the important settings we would like to have at hand during gameplay.

In summary – the Panasonic Z85A is equipment that truly surprises with its gaming capabilities. It is a television on which both console gamers and PC players will feel at home. It is smooth, dynamic, and simply good.
