horizontal scan rate

hardware (HSR) The measure of how many scan lines of

pixels a monitor can display in one second, expressed in

kHz (generally somewhere between 20 and 100 kHz).

The HSR is controlled by the horizontal sync signal generated

by the video controller, but is limited by the speed with

which the monitor can scan the electron beam horizontally

across the screen and then return it to the beginning of the

next line.
