TV experiences sharp picture quality, even when you are watching fast-moving images like sports or action movies. Clear Motion Rate was developed to accurately measure how well an LCD or LED TV can depict fast-moving images. Previously, motion-clarity was calculated by the frame refresh rate alone. But CMR offers a more complete measure by calculating 3 factors: frame refresh rate, image processor speed and backlight technology. LED TVs with a CMR of 60 to 120 can display action-packed movement with sharp detail and vivid contrast while eliminating image distortion.
