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.
