A monitor's refresh rate, or vertical scan rate, is the number of times in a second a monitor redraws a picture. Refresh rate is not the same as frame rate, an attribute that concerns many video game players and some movie viewers. Frame rate measures how many times per second the source image changes. Refresh rate is how many times per second the monitor redraws the image. A monitor will redraw an image at the same rate no matter what the frame rate of the game, movie, video, or other source.
I'm not sure of the engish term but I think it's retinal persistence. the problem is that the eye has not the same refresh rate on all it's surface. I got sensitive eyes and that's why I'm very picky about refresh rates. i need 80Hz to feel comfortable when looking at the screen. any lower i can see it flash.
