Pros
Pro Great overall picture quality
The overall picture quality of the Sony X900F is on par with what the best, high-end TVs in its price range offer. The X900F offers excellent performance when it comes to both bright and dark scenes thanks to its ability to recreate bright and vivid colors as well as some deep blacks.
Pro Exceptional smoothness of motion
The Sony X900F does an excellent job of reproducing smooth and fluid motion thanks to its advanced flickering capabilities. The panel can flicker at the rate of 720 Hz which can eliminate motion blur. Only a few panels in this price range can flash that fast, which is good, as the majority of viewers will not notice such fast flickering.
Additionally, unlike the overwhelming majority of TVs present in this price range, the X900F can perform local flickering which ensures that the flickering doesn't take its toll on the overall brightness. Worth noting that the regular flickering of an LED panel reduces its brightness by about a half which can de-saturate some highlights and degrade the image.
Pro Colors are accurate
The Sony X930F doesn't need calibration because its out-of-the-box color accuracy is very high. The overall color inaccuracy measures at the dE of 2.4. A human eye can not spot such a tiny color inaccuracy.
