Report Abuse. Monitors have a refresh rate measured in hertz. If it's a CRT, you'll need to check your manual or Google your model number, but if it's an LCD, it should be sixty hertz. Many components within your PC also have an associated speed for which they can cycle between on an off (hertz).
Hertz can be used to measure any periodic event; the most common uses for hertz are to describe radio and audio frequencies, more or less sinusoidal contexts in which case a frequency of 1 Hz is equal to one cycle per second.
