To display a program at a specific resolution, you must install the appropriate video drivers and your monitor must support the resolution. Similarly, the number of colors that a program can display depends on the capabilities of the monitor, the video driver, and the amount of memory 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 adapter, 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 environments 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 expansioncard connector. Video adapters can include memory separate 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 simultaneously displayed. Video adapters can also include their own coprocessor chip for faster graphics rendering. 14 Dell PowerEdge 2300 Systems User's Guide

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-

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

connector
.
YLGHR±DGDSWHU
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.
