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 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)

that EDID information.
Or
From the File menu, select Open File to select an .edid file to be written to the DVI or HDMI input
connector.
4. Click Write to write the EDID information to the input connector.

If applicable – Repeat any of the steps that are necessary for any additional 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.
