4.0 EDID Management
In most installations no user setup or configuration is needed. As shipped from the
factory, the EDID routing mode of the wall plate is set to pass the EDID of the connected
projector to the source. However the VSA-HA-DP has its own alternate internal EDID
memory that can be used instead of the actual EDID of the projector.
There are several scenarios where a user may want to "emulate" a different EDID than
the one in the actual projector. For example if the projector supports a variety of "strange"
resolutions, one may want to eliminate those to get a more predictable behavior.
To change the EDID routing mode from Pass-thru (default) to Emulate, the USB
connector on the front panel must be used (USB cable for connection to a PC), and the
user must download and install the free Windows™ GUI from the product's webpage.
Using the GUI you can configure the wall plate to use its internal EDID table. As shipped,
the internal EDID has the settings shown in the table below (highlighted row is the
native). The internal EDID table can be overwritten either by: (1) learn the EDID from
connected projector (read and copy EDID from the projector to the internal EDID
memory), or (2) upload an EDID table from the PC.
The following lists the default resolutions of the VSA-HA-DP internal EDID. Performing a
Factory Default reset using the GUI will restore these values are reset.
