Writing EDID Data to a DXLink Transmitter’s HD-15 (VGA) Input Connector
The instructions that follow tell how to use the EDID Programmer view to write user defined VGA EDID
information to the HD-15 input connector on a DXLink Transmitter. User defined VGA EDIDs are currently
available from technical support. A library of VGA EDID files will be available on at
www.amx.com
in
conjunction with a future firmware release.
To write VGA EDID data to a DXLink Transmitter:
1.
Download the VGA EDID set provided by technical support.
2.
On the PC, open the DGX Configuration Software and select the EDID Programmer tab.
3.
Under Inputs/Outputs on the left, expand the device tree, and select the HD-15 input.
4.
From the File menu, select Open File to select the VGA .edid file that was downloaded in Step 1.
5.
Click Write to write the VGA EDID information to the HD-15 input.
Tip:
You can confirm that the new VGA EDID data was written to the HD-15 input by selecting the HD-15
input and clicking on the Read button
or
by using the SEND_COMMAND
?VIDIN_EDID
, which will return:
VIDIN_EDID-USER EDID 1
.
Important:
You can revert to the factory default EDID for the HD-15 input by using the SEND_COMMAND
VIDIN_EDID-ALL RESOLUTIONS
(i.e., AMX_0500_003).
