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 183), 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/Video Concerns
HDMI, DVI, DXLink Twisted Pair, or DXLink Fiber 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.
The HDMI and DXLink Twisted Pair Boards are preprogrammed with the equivalent of the file
“AMX_HDMI1v3__Standard.edid” to support basic audio only (2 CH L-PCM 32 kHz, 44.1 kHz, and 48 kHz).
The DXLink Fiber Boards initially do not have EDIDs loaded; however, they obtain EDIDs (on a per channel basis)
as soon as they are connected to DXLink Fiber Transmitters. The DVI Board is preprogrammed with the equivalent of
the file “AMX_DVI1v1_BaseBlockOnly.edid.” Both files are in the AMX_EDID_Library.
The files in the following two tables are located in the AMX_EDID_Library file at www.amx.com (search for EDID
Library). Additional files provided in the EDID Library include support for 3D deep color and High Bit Rate (HBR)
Audio.
Files using 1080p (VIC 16) as the preferred and native video resolution:
Files using 720p (VIC 4) as the preferred and native video resolution:
