What reviewers say

The 55-inch What Hi-Fi? and TechRadar reviews praise natural, detailed pictures, motion, upscaling and unusually capable TV sound. Both find the price high and HDMI connectivity restrictive. Their missing VRR criticism describes launch firmware; current Sony specifications confirm VRR. What Hi-Fi? also hears distortion at very high volume.
