Enjoy smoother motion and transitions on this Sony BRAVIA 4K TV with high 120-Hz refresh rate. You'll also see sharp details in fast-moving scenes with Motionflow™ XR. This innovative technology creates and inserts extra frames between the original ones, comparing key visual factors on successive frames then calculating the split second of missing action in the sequences.
The Separated Notch Edge on the X-Balanced Speaker Unit improves vertical amplitude symmetry-an essential for clear sound quality. It achieves this using strategically placed cuts on the edge, which help to control the stress inside and outside the edge of the diaphragm.
