CONFIGURATION
EDID
(extended display identifi cation data)
Video output devices transmit their EDID to the connected graphics card via the
Display Data Channel (DDC).
Your 3-Channel DVI Extender TX uses all twelve optical fi bers in your fi beroptic cable
exclusively for signal transmission. Therefore it is not possible to transmit the EDID of the
monitor from the 3-Channel DVI Extender RX back to the computer, connected to the 3-
Channel DVI Extender TX.
The graphics cards receive the required EDID parameters from an EEPROM containing
the default settings for each DVI-IN input on your 3-Channel DVI Extender TX.
BLACK BOX recommends working with the actual EDID of your video output devices.

EDID INTERNAL and DEFAULT

In the factory default settings, the default BLACK BOX EDID is preset on all three DVI IN
input ports under INTERNAL:
The default settings shown here should be
overwritten with the actual EDIDs from the
video output devices via EXTERNAL
(page 25).
NOTE:
You can reset the default EDID via DEFAULT.
Use the STORE command to save the default
settings in INTERNAL.
The DETAILS sub-menu is used by BLACK
BOX for error diagnosis.
