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 vice-versa you will
need a DVI Detective.
*For the Dell 30" Display the internal and external equalization knobs will both need to
be adjusted to get a clean video signal. The internal EQ can be reached by removing 9
screws situated on the sides of the casing and the 6 hex nuts on the DVI connectors.
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 di-
rectly. Start your computer up and try switching. If your USB devices do come up nor-
mally 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.
