Introduction
The ex•tend•it DVI Detective reads and remembers the EDID of your display.
The DVI Detective allows you to use Gefen’s DVI-DL on computers that
require an EDID on boot up. It also allows you to use Gefen’s DVI
Switcher or ADC Switcher without having to be selected to the computer
that is booting up.
How it works
Connect your DVI or ADC monitor to the ex•tend•it DVI Detective
and then power the DVI Detective. The ex
•tend•it DVI Detective then
reads the EDID of your display, and once the LED stops blinking the
ex
•tend•it DVI Detective has remembered the EDID of your display.
You can now connect your ex
•tend•it DVI Detective to your computer
with a short DVI cable, and then connect it to your ex
•tend•it DVI-DL,
ex
•tend•it DVI Switcher or ex•tend•it ADC Switcher.
