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.
AMX EDID Library
A library of VGA EDID files are available at www.amx.com (search for EDID Library). This library provides EDID files that can be used
with AMX products. A report is provided for each EDID file, which describes the EDID features in detail, in order to assist you in
selecting the most appropriate EDID for your system needs.
Check the Library to determine if one of the custom EDID files meets your needs. (The custom EDID files are variants of
base/standard EDIDs.)
DGX Configuration Software can be used to reprogram the EDID on the input port with one of the .edid files provided in the
EDID Library.
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).
