Appendix A – EDID Programmer
Important: Any analysis or editing of the EDID data necessary to support the equipment specific to
your installation will need to be done separately prior to using the EDID Programmer. A variety of
freeware tools can be found on the web to help with these tasks.
Keep in mind that the EDID information for some equipment may not be compatible with the remaining
equipment even with programming. In those cases, the signals will have limited routing options.
Tip: If the signal from some of the equipment can only be routed to part of the destinations due to
incompatible EDIDs, control can be simplified by creating a separate virtual matrix for the inputs and
outputs involved. To request a modified configuration file with new virtual matrices, contact technical
support (see page43) or see the XNConnect Help file for directions.
The remaining sections provide information on:
Determining the Need for EDID Programming
Ideally the EDID analysis will have been completed during installation specification. Consideration
should be given to the use of DGX SC Fiber output boards and corresponding DGX SC Fiber Receivers
which (in almost every case) will remedy incompatible source and destination resolution issues. Specific
attention should be given to local output boards which do not provide automatic scaling via the
SmartScale™ functionality. If this was not possible but all of the system's devices are now available, the
most effective way to proceed is to test if the signal from each of the source devices can be routed
through the Epica DGX 16 or 32 to each of the destination devices. If they can be routed, then EDID
programming is not necessary.
A method of control is not specified in the following instructions. Any DGX TX and RX Modules for
the system need to be installed before completing the following procedure.
To determine if EDID programming is necessary:
1.
Route the first input to all of the applicable outputs.
2.
Check each destination display to verify that the picture is present, making note of any that are not.
3.
Repeat the Steps 1 and 2 for each of the remaining inputs.
Important: If any of the destinations do not display a picture, analysis or editing of the EDID data
may be necessary prior to using the EDID Programmer. A variety of freeware tools can be found on
the web to help with these tasks.
Installing the EDID Programmer
PC System Requirements for EDID Programmer v1.2.0
* The installation process requires 20 MB of disk space for the EDID Programmer installer. Once
installed, the EDID Programmer requires 5 MB of disk space.
** We strongly urge the user not to use video cards with DMS-59 connectors. Video cards with DMS-59
connectors have been shown to fail consistently and, in the worst case, can corrupt an EDID data file. A
laptop PC with a VGA or DVI out is a good solution. Cards with 2 DVI connectors, 2 VGA connectors,
or 1 DVI and 1 VGA connector are also acceptable.
