Overview
The VS-291/VS-491 Video Switches are control units that allow
you to conveniently display the video output of two (VS-291) or
four (VS-491) separate computer systems on a single monitor,
thereby eliminating the unnecessary expense of purchasing a
separate monitor for each computer. The units use electronic
switching technology, rather than mechanical switching, for
greater reliability and durability.
The VS-291/VS-491 also saves on the space that additional
monitors take up, as well as the extra power costs, and eliminates
the inconvenience and wasted effort involved in constantly
moving around from one computer to another.
