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.
