ABOUT YOUR INTERFACE

2

There are many types of computers and computer
video cards on the market today. There are also
numerous data monitors and large screen data
projectors. When a computer image is displayed on
a large screen data projector or on a large screen
monitor, it often becomes clear that some
computers are not always compatible with certain
display devices. The

 VA6834FC

 is a computer

video interface designed to resolve this
incompatibility.

The 

VA6834FC

 is a dual output computer video

interface. It is designed to interface a single VGA/
SVGA/XGA/UXGA/MAC/SUN or SGI computer
video source to two scan-rate compatible
presentation monitors or data projectors.

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

 VA6834FC

 is a state-of-the art piece of

equipment with an exceptional combination of
compact size, advanced features and very
competitive pricing.
