X1 processor for sublime picture quality – whatever you’re watching

The sophisticated X1 processor takes account of the fact that not all UHD 4K signals are equal. A RAW 4K UHD signal from a 4K UHD player requires different processing than a Netflix 4K signal or a USB video signal. Sony's X1 processor analyses every signal and optimises it for the best performance possible. Thanks to Sony's X-Reality PRO 4K technology, standard images from TV and other sources are taken as close to UHD 4K resolution as possible, for stunning clarity.

Motionflow XR 1000Hz from a native 100Hz screen for smooth motion
This Sony is also fitted with a native 100 Hz screen for faster refresh rates. Combined with Sony's stunning Motionflow XR 1000Hz, this screen gives the Sony amazingly smooth motion, that's both crisp and steady. Whether you're watching a fast-moving action movie or sports event, the Sony KD55XF8577 remains rock steady.
