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.
If you loose your picture when switch from source 1 to source 2 or viasaversa
you will need a DVI Detective.
The external equalization knobs can be used to balance out signal noise result-
ing from long cables for better picture quality.
*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.
