The Gefen EXT-DVI-144M is a 1x4 DVI Monitor Switcher which works in reverse from our other switchers: it connects one high definition digital video source to four digital video displays one at a time. You switch to whatever display you want to view at any given time. This DVI monitor switch is ideal for environments that need to assign a main video source to several different displays, such as the home, office, recording studio or industrial complex that needs video in different rooms or at different desktops. Monitor selection is done via the IR remote control that comes with the unit. Full HDMI (audio and video) can also be accommodated using HDMI to DVI adapters (sold separately) on the input and output of the unit.

How the Gefen 1x4 DVI monitor switch works:

Connect your DVI source to the DVI Monitor Switcher using the DVI (male to male) cable that comes with the unit. Then connect up to four digital displays to the Switcher's DVI outputs. Once all the components are powered and connected, you select which display you want to view using the IR remote.
