Multisync monitor
Encyclopedia
A multisync monitor is a monitor
that can properly synchronise
with various horizontal
and vertical scan frequencies
. In contrast, fixed frequency monitors can only synchronise with a specific horizontal and vertical frequency, limiting their flexibility. Multisync monitors became commonplace during the 1990s
as desktop computer systems began to support an increasing number of display resolutions:
Fixed frequency monitors, and multisynchronous monitors that only support a set of frequences, may upon receiving scan frequencies outside design limits overheat their transformers. This is especially true for vertical scanrate.
Some monitors have protection circuits that will block invalid scan frequencies.

Synchronization
Synchronization is timekeeping which requires the coordination of events to operate a system in unison. The familiar conductor of an orchestra serves to keep the orchestra in time....

Horizontal scan rate
Horizontal scan rate, or horizontal frequency, usually expressed in kilohertz, is the frequency at which a CRT moves the electron beam from the left side of the display to the right and back, and therefore describes the number of horizontal lines displayed per second...

Frequency
Frequency is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency.The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the frequency...
