Direct LED backlight with full-array local dimming and Triluminos colour. AVForums and Expert Reviews counted 48 dimming zones on their 55-inch review samples; Sony does not publish a series-wide count. X-Motion Clarity is picture processing, not a native refresh specification.

HDTVTest found forced interpolation on 3D Blu-ray films in its 40-inch test, with judder when defeated using Game Mode.	Sony describes X-Motion Clarity but its exact UK size sheets do not publish a native refresh figure, so no Hz value is assigned to the series.
Viewing angle
Viewing angle	HDTVTest observed colour and contrast washout beyond about 45 degrees off-axis on its 40-inch sample.	AVForums and Expert Reviews report the 55-inch LCD's contrast and colour degrade when viewed from the side.
