INTRODUCTION

The 1:4 VGA Hub allows a computer with a VGA graphic card to connect to up to
four VGA compatible monitors or projectors at the same time. Because it allows
one computer to drive multiple monitors for simultaneous viewing, the 1:4 VGA Hub
can be used to set up additional monitors in the workspace or to assist presentation
environments by sending graphics to both monitors and projectors at the same time.

How It Works

Simply connect your computer’s VGA graphic port to the 1:4 VGA Hub’s input using
the supplied cable. Up to four analog monitors or projectors are connected to the
Hub’s four VGA outputs. VGA output 1 is the primary connection and is used for the
main display. VGA output 2, 3 and 4 will mirror the primary connection.

OPERATION NOTES

READ THESE NOTES BEFORE INSTALLING OR

OPERATING THE 1:4 VGA HUB

• Display information (EDID) is not sent back to the source. Standard VESA
resolutions should be output by most computers without the need of an EDID.
If using a non-VESA standard resolution or if EDID is needed, an EDID storage
and relay device is necessary. Gefen recommends the use of a DVI Detective
(part #EXT-DVI-EDIDN or EXT-DVI-EDIDP) with two VGA to DVI adapters.
