Appendix C
Video Monitor Systems
There are many video display systems available for use with
your computer system. This appendix will provide a brief
description of the most common video system types, and
discuss their applications.
Monitor System Resolution
The main difference between video monitor system types is
their screen resolution. The monitor’s resolution is important
because it determines the number of characters that can be
displayed on the screen at any one time, and the quality of any
screen graphics displayed.
The image displayed on the video screen is made up of a large
number of individual dots. This is true whether the displayed
screen image is made up of text or graphics, or is a mixture of
both. The higher the monitor’s resolution is, the smaller the
individual dots can be. Smaller dots means that more of them
can be displayed in the same space. If more dots are displayed,
then more text characters and better looking graphics can be
displayed.
Video Controller Boards
The video controller board controls the actual number of dots
sent to the screen. A video system’s resolution capability is
usually described as the number of dots that can be displayed
horizontally by the number of dots that can be displayed
vertically.
