What are the basic measures of the monitor video parameters ?
There are two primary measures of the maximum effective pixel addressability and refresh rate that a monitor is capable of. The maximum rate that a monitor can refresh the screen is measured in Hertz (cycles/second) and is called the vertical refresh rate (or vertical scan rate). The horizontal scan rate is the number of times that the monitor can move the electron beam horizontally across the screen, then back to the beginning of the next scan line in one second.
