Что (кто) такое horizontal scan rate - определение
THE REPETITION OF LINES ON A DISPLAY DEVICE
Horizontal scan frequency; Horizontal sync
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.

Horizontal scan rate
Horizontal scan rate, or horizontal frequency, usually expressed in kilohertz, is the number of times per second that a raster-scan video system transmits or displays a complete horizontal line, as opposed to vertical scan rate, the number of times per second that an entire screenful of image data is transmitted or displayed.
refresh rate
FREQUENCY AT WHICH A DISPLAY HARDWARE DISPLAYS A NEW IMAGE

<hardware> (Or "vertical refresh rate", "vertical scan rate")
The maximum number of frames that can be displayed on a
monitor in a second, expressed in Hertz.
The scan rate is controlled by the vertical sync signal
generated by the video controller, ordering the monitor to
position the electron gun at the upper left corner of the
raster, ready to paint another frame. It is limited by the
monitor's maximum horizontal scan rate and the resolution,
since higher resolution means more scan lines. Increasing
the refresh rate decreases flickering, reducing eye strain,
but few people notice any change above 60-72 Hz.
