Motion handling–X-Motion Clarity. Current Sony firmware adds 4K 120 Hz signal support; the original video-signal table still lists 4K only up to 60 Hz. RTINGS reports blurred text/halved vertical detail in some 4K 120 Hz modes, so signal support does not assert uncompromised full-resolution rendering.
