4.4. EDID menu
Advanced EDID Management can be accessed by clicking on the EDID menu. This
view is divided in two segments. The upper segment can be opened by clicking the
green arrow. This segment contains the EDID editor. The lower segment is the
EDID router area. This consists of two list windows, which can display a selected
part of the EDID memory.
Info
When the user enters the menu for the first time, the software starts to download
the whole EDID list from the matrix. It may take about 30-40 seconds.
4.4.1. EDID Router operation
After the list is downloaded, the current status is shown. The EDID memory
consists of four parts. Any memory part can be displayed on either side by using
the drop down lists.
The Emulated EDID List shows the currently emulated EDIDs for each input. It
contains the resolution, manufacturer and vendor name of the EDID reported to the
sources for each input separately. The source column displays the memory
location that the current EDID was routed from (Mem0 is shown as source if the
source was changed after it was copied to an input). The rows with red background
are dynamically routed to the input.
The Last attached Monitor's EDID List contains the resolution, manufacturer and
vendor name of the display devices connected to matrix switcher's output. The
matrix remembers the last display device‟s EDID, so there is an EDID shown even
if there is no device attached to the router‟s output at the moment.
The Factory EDID List shows the factory memory locations (01# - 50#) with
preprogrammed EDID.
The User EDID List shows the memory locations (51# - 100#) which can be used
by the user to save custom EDIDs.
Any DVI source reads the EDID from the Emulated EDID memory for the
corresponding port. The user can copy an EDID from any of the three EDID lists to
the desired input‟s memory location. This is called EDID routing. There are two
types of the emulation: static and dynamic.
Changing the emulated EDID at one or all inputs

Figure 4-5. EDID Management menu
Static EDID emulation happens, when an EDID from the Factory or User
EDID list is routed to an input
Dynamic EDID emulation occurs, when an attached monitor‟s EDID is routed
to an input. In this case the emulated EDID changes automatically, if a new
monitor is attached to the output, by simply copying the data from the monitor.
