4.3.2 DDC/EDID
Settings
These settings are accessed in NORMAL operating mode (CFG indicator is off).
The MultiView™ II DVI-TX features the ability to send DDC/EDID display identifiers to the video source in order
to determine display capabilities. The DDC/EDID interface is a data communication channel used between
plug
and play
devices to accurately report a display's capabilities and identify the manufacturer. If this data is not
available, the video source may revert to a low resolution or not display at all.
The DVI-TX unit has three DDC/EDID modes of operation. When the DVI-TX is operating in “normal mode” (
CFG
indicator is off),
it is possible to quickly select between the three operating modes simply by using the
DDC
MODE
button at any time.
STD: Selects the Magenta Magic DDC/EDID profile
This is the factory default mode which uses generic DDC/EDID information stored within the
transmitter. It is also referred to as the
Magenta Magic profile
, and it is comprised of a set of
common video resolutions which are intended to support the most popular VESA standards in
standard or widescreen formats.
To activate STD mode, press the
DDC MODE
button until the
STD
indicator is on.
LOCAL: Selects the DDC/EDID profile from a locally-connected display
The DDC/EDID information is transferred from a display connected to the local port of the
transmitter back to the video source. This is only effective if a display is connected to the “local out”
port - and it must remain connected at all times. This mode
does not
store any DDC profile
information inside the DVI-TX device.
To activate LOCAL mode, press the
DDC MODE
button until the
LOCAL
indicator is on.
COPY: Selects a previously stored copy of a DDC/EDID profile
In this mode, DDC/EDID information comes from a DDC profile that was previously copied into the
DVI-TX’s non-volatile memory from a display device.
To use this mode, a DDC/EDID profile must already have been stored into the DVI-TX.
To perform a DDC-copy operation
:
Set the DDC mode to “COPY” using the
DDC MODE
button.
Connect a display to the LOCAL OUT port. The display must be powered on.
Push and hold the
COPY
button until the copy-status indicator flashes 3 times, indicating
the operation was successful.
If it only flashes once, the operation failed and the previously stored DDC profile (if any)
will remain unchanged.
