Our Verdict
Sony X850F
LG UK6570
The Sony X850F and the LG UK6570 are very similar overall. The X850F is brighter in SDR and HDR and has a wide color gamut. The X850F has better overall motion handling, with slightly faster response time, nearly flicker-free backlight, and better motion interpolation thanks to the 120 Hz panel. The LG UK6570 has much lower input lag, great for gaming or use as a PC monitor. The 85" X850F uses a VA panel, compared to the 86" UK6570 that has an IPS panel, so the XBR85X850F likely will perform better in a dark room.
