Speciﬁcations

Warranty

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 VGAgraphic port to the 1:4 VGAHub’s input using

the supplied cable. Up to four analog monitors or projectors are connected to the

Hub’s four VGAoutputs. VGAoutput 1 is the primary connection and is used for the

main display. VGA output 2, 3 and 4 will mirror the primary connection.

INTRODUCTION

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.

CONNECTING AND OPERATING THE 1:4 VGA HUB

How to Connect the 1:4 VGA Hub to your devices

ing a non-VESA standard resolution or if EDID is needed, an EDID storage and re-
