You may not be able to use your mouse with all types of software.
The Monitor
Your computer is supplied with a Super VGA (video graphics array)
display adapter. You can use a VGA, or Super VGA monitor (in
various sizes) with your computer. Contact RM for more
information on monitors or consult your RM Sales catalogue.
Information appears on your monitor in either text or graphics
modes, depending on the software you are using. Both text and
graphics modes use a display of pixels. These are tiny dots that
light up to form a screen message or picture. Each dot can be a
different colour (or intensity level on a monochrome monitor).
In text mode, there are usually 80 columns and 25 rows in which
characters appear. Each character is formed from a number of
pixels.
In graphics mode, these pixels are in a denser matrix of columns
and rows; for example, 640 columns and 480 rows. Windows uses
graphics mode.
