Writing EDID Data to DGX DXLink, DVI, or HDMI Input Connector
The instructions that follow tell how to use the EDID Programmer view to write the EDID information from an
output or from a saved file to the EDID chip for an input connector on a DGX DXLink, DVI, or HDMI Input
Board.
To write EDID data to the EDID chip for an input connector:
1. In the DGX Configuration Software interface, select the EDID Programmer tab.
2. Save the board's EDID default as a backup (assumes the board has factory default EDID programming) .
a.
Select the input connector.
b.
Click Read.
c.
From the File menu, select Save to File (select location, enter file name, and click Save).
3. If an EDID was just read from an output (see page 164), select the input to which you want to write that
EDID information.
Or
From the File menu, select Open File to select an .edid file to be written to the DXLink, DVI, or HDMI input
connector.
4. Click Write to write the EDID information to the input connector.
5. If applicable – Repeat any of the steps that are necessary for any additional DXLink, DVI, or HDMI input
connectors.
Custom HDMI and DVI EDID Files for Handling Audio Concerns
HDMI, DVI, or DXLink Boards will be connected to multiple source and sink devices. These devices often
support different video and audio formats. Potentially, neither the video nor the audio routed by the system can be
displayed on one or more of the destination devices.
Customizing the EDID content at the Enova DGX input channels is one way to be sure that the formats provided
by the source are compatible with most/all of the destination devices.
