There are several varieties of computers and
computer video cards on the market today. There
are also numerous data monitors and large screen
data projectors. When displaying a computer
image on a large screen data projector or on a
large screen monitor, it often becomes clear that
some computers are not always compatible with
these display devices. The VA6831FC is a
computer video interface designed to resolve this
incompatibility.

computer video interface designed to resolve this
incompatibility.
The VA6831FC is a dual input-switchable computer
video interface. It is designed to interface up to two
VGA, SVGA, XGA, UXGA, MAC, SUN, or SGI
computer video sources to one scan-rate
compatible presentation monitor or data projector.
Each of the inputs can be connected to different
types of computers simultaneously. The VA6831FC
will amplify video signals and convert the sync
portion of the signal to the desired format.

It is important to understand the general
capabilities of interfaces. Interfaces do not change
the scan-rate or the resolution of the video signal.
An interface simply converts a computer video
signal to a pre-selected analog format. The source
(computer) and display (projector or monitor) must
be scan-rate compatible.
