away from the work area.

trol, information distribution, conference room presentation, and school and corporate
training environments.

mouse. The DL cross platform switcher saves space - there’s no need to work on a desk
crowded with double displays, keyboards and mouse devices. It saves time - there’s no
need to move from one monitor to another to access different computers. And, it saves
money - there’s no need to purchase additional displays, mouse devices, keyboards etc.

2x1 DVI DL OPERATION NOTES
Operation Notes
When turning on or rebooting your computers, the DVI DL Switcher must be
selected to the computer that is booting until the computer completes the boot
cycle. This step can be eliminated using the Gefen DVI Detective, which stores
the displays EDID.
If you loose your picture when switch from source 1 to source 2 or viasaversa
you will need a DVI Detective.
If you are experiencing USB dropouts try using the switcher just as a USB
hub by only connecting the USB cables from your computers to the switcher.
Connect your devices to the USB out portion of the switcher and connect your
display to your computer directly. Start your computer up and try switching. If
your USB devices do come up normally then you will need a DVI Detective to
negotiate the video/USB signals for faster switching. If they do not come up
normally, then you will need to call tech support.
