What are the typical screen refresh rates in PC systems ?
The refresh rates are somewhat standardized; common values are 56, 60, 65, 70, 72, 75, 80, 85, 90, 95, 100, 110 and 120 Hz. This is done to increase the chance of compatibility between video cards and monitors. The refresh rate is important because it directly impacts the viewability of the screen image. Refresh rates that are too low cause annoying flicker that can be distracting to the viewer and can cause fatigue and eye strain. The refresh rate necessary to avoid this varies with the individual, because it is based on the eye’s ability to notice the repainting of the image many times per second. Some notes on refresh rates: • Most individuals notice flicker at refresh rates below 60 Hz and many have a problem with flicker at 60 Hz • Very few people notice flicker at refresh rates above 72 Hz Note that this also depends on the size of the monitor. Flicker is easier to see on a larger monitor than on a small.
