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.
Thanks to the tools available in E7NQ PRO, we managed to extract quite a decent image from it, especially with lower quality content. After refining the white balance of the SDR materials, the colours look much more natural, and what we see on the screen seems closer to the vision that the manufacturer intended to present. Additionally, we improved the brightness characteristic (Gamma), which means the television is no longer prone to excessive brightening, and everything presents itself distinctly better than before our intervention.
We also managed to achieve some results with HDR materials, although it isn’t quite as rosy here. Indeed, the white balance has approached an acceptable level, but the problem lies elsewhere. It concerns the EOTF curve, which is the way the television manages brightness and tonal range of the image. At first glance, it might seem that the biggest issue only relates to mid-tones being overly brightened. However, after more detailed testing and enabling the filters for displaying the EOTF curve, it becomes apparent that the receiver tends to brighten the entire screen. This appears to be a limitation arising from the small number of local dimming zones and generally modest brightness management capabilities. Such hardware limitations are simply insurmountable. Despite this, after our calibration, the image is noticeably better than at the outset. One just needs to be aware that in terms of contrast and brightness management, this model has its limits, which even good calibration cannot fully overcome.
