graphics board manual for information.

 

 

Flicker

The term “flicker” refers to noticeable shimmering that occurs when the image on the screen is redrawn (“refreshed”) too slowly. A refresh rate of 80 Hz means the image is redrawn 80 times per second. Most people will notice flicker at image refresh rates as high as 60 or 70 Hz, whereas refresh rates of 72 Hz or above usually is not noticeable. Flicker is known to be the cause of visual fatigue.
