What happens with tearing is that halfway through this process, the image changes - a very likely event. Because of this, the monitor displays the first half the first image, and the next half it shows the new image, thinking it's all the same image. The mistake will be "corrected" in the very next refresh, as then the entire screen will be the new image - too slow. Our eye already caught the mistake. With extremely high refresh rates (150hz+), tearing is practically unnoticeable.

I must admit I don't get the above paragraph 100%, can somebody elaborate? Rich? Diego
