To display a program at a specific resolution, you must install the appropriate video drivers and your monitor must support the resolution.

Graphics-mode application programs and operating environments, such as Windows, often require video drivers to display at a chosen resolution with the desired number of colors.

Abbreviation for video graphics array. VGA
and SVGA are video standards for video
adapters with greater resolution and color
display capabilities than EGA and CGA,
the previous standards.
To display a program at a specific resolu-
tion, you must install the appropriate
video drivers and your monitor must sup-
port the resolution. Similarly, the number
of colors that a program can display de-
pends on the capabilities of the monitor,
the video driver, and the amount of mem-
ory installed for the video adapter.

On some systems with a built-in VGA
video adapter, a VGA feature connector
allows you to add an enhancement adapt-
er, such as a video accelerator, to your
computer. A VGA feature connector can
also be called a
VGA pass-through
connector

The logical circuitry that provides—in
combination with the monitor or display—
your computer’s video capabilities. A
video adapter may support more or fewer
features than a specific monitor offers.
Typically, a video adapter comes with
video drivers for displaying popular
application programs and operating envi-
ronments in a variety of video modes.
On most current Dell computers, a video
adapter is integrated into the system
board. Also available are many video
adapter cards that plug into an expansion-
card connector.
Video adapters can include memory sep-
arate from RAM on the system board. The
amount of video memory, along with the
adapter’s video drivers, may affect the
number of colors that can be simulta-
neously displayed. Video adapters can
also include their own coprocessor chip
for faster graphics rendering.
YLGHR±GULYHU
Graphics-mode application programs and
operating environments, such as Win-
dows, often require video drivers to
display at a chosen resolution with the de-
sired number of colors. A program may
include some “generic” video drivers.
Any additional video drivers may need to
match the video adapter; you can find
these drivers on a separate diskette with
your computer or video adapter.
YLGHR±PHPRU\
Most VGA and SVGA video adapters in-
clude VRAM or DRAM memory chips in
addition to your computer’s RAM. The
amount of video memory installed prima-
rily influences the number of colors that a
program can display (with the appropriate
video drivers and monitor capability).
YLGHR±PRGH
Video adapters normally support multiple
text and graphics display modes. Charac-
ter-based software (such as MS-DOS)
displays in text modes that can be defined
as
x
columns by
y
rows of characters.
Graphics-based software (such as Win-
dows) displays in graphics modes that can
be defined as
x
horizontal by
y
vertical pixels
by
z
colors.
