DVI Boards
The DVI Input Boards come pre-loaded with EDIDs typical for DVI output devices (computer monitors, etc.) which do not
support embedded audio signals. However, they will allow HDMI with embedded audio formats through if the default
EDID setting is changed via DGX Configuration Software using a file from the EDID Library (see Option 2 below).
HDMI Boards
The HDMI Input Boards come preloaded with EDIDs typical for HDMI output devices (DVD players, etc.). However, they will
allow DVI formats through if the default EDID setting is changed via DGX Configuration Software using a file from the EDID
Library (see Option 2 below).
Options for Re-programming EDIDs
If EDID re-programming is necessary, use one of the following two options.
Option 1:
Install the DGX Configuration Software and open the EDID Programmer view. Read the EDID from the
output connected to the destination device and write it to the DXLink, DVI, or HDMI input connector.
Option 2:
Install the DGX Configuration Software and open the EDID Programmer view. Check the
AMX_EDID_Library file at www.amx.com (search for EDID Library) to determine if one of the custom EDID files
meets the needs of the equipment. (The custom EDID files are variants of base EDIDs.) Open and write the custom
EDID file to the DXLink, DVI, or HDMI input connector.
NOTE:
If you have changed EDID from the default (which supports 2 channel L-PCM as embedded audio) and are
experiencing audio problems, it may be because you are trying to pass Dolby or DTS or high PCM frequency rates and the
destination device does not support them. If you are experiencing video problems, it may be because you are trying to
pass a video format that the destination device does not support. In either of these cases, re-programming the EDID
(below) or re-routing the signal via the System Configuration interface to an Audio Switching Board’s down-mix channel
(see page 130) may help resolve the problem.
Reading and Saving EDID Data from a Destination Device
In the EDID Programmer view, the Save to File option under the File menu can be used to save the EDID information as an
.edid file. The saved file can be opened as a text file (from the File menu, select Open File) and edited or opened and
written to an input (click the Write button).
The instructions that follow tell how to use the EDID Programmer view to read and save the EDID information from an
output, which is receiving the EDID information from a destination device.
DXLink Fiber hardware in Unidirectional or Data Link-lost Mode – EDID timings are not accessible as there is no
return path available to receive the information.
The availability of the Read and Write buttons depends on whether an input or output is selected in the device
tree on the left. (Read from an output and write to an input.)
Reading and Saving EDID Data
1.
On the PC, open the DGX Configuration Software and select the EDID Programmer tab (FIG. 166):
2.
From the Inputs/Outputs device tree on the left, select an output from which to read the EDID information that it
receives from the destination device.
