satisfaction is very important to us.

technologies. Gefen’s reliable plug-and-play products supplement cross-platform

The Gefen 4x1 DisplayPort Switcher
Easily switch between four computers using DisplayPort with the 4x1 DisplayPort
Switcher.
The rack-mountable 4x1 DisplayPort Switcher offers an economical solution for
switching between four different computers to one display location at the touch of
a button.
Eliminating the need to purchase many displays in a studio or professional en-
vironment, this versatile solution saves money, supports both Mac and PC-type
computers, and offers uncluttered and increased desktop space.
This Switcher can be controlled using front panel discrete switching, the included
IR Remote control, IP control, or the RS-232 port for switching automation.
The 4x1 DisplayPort Switcher is compatible with all operating systems using
DisplayPort.
How It Works
Connect the four included 6-foot DisplayPort cables between the computers and
the Switcher inputs. Connect the Switcher output to the monitor using a Display-
Port cable. Connect the included 5V DC locking power supply to the 4x1 Switcher
and connect the AC power cord to an available electrical outlet. The currently
selected source will be displayed.
