User-assigned EDID mode
In this mode, you can select an EDID file that is stored on the switcher at the factory. The
selected EDID is stored in memory for the inputs and is not overwritten. The switcher
does not obtain EDID information from the display.
You may want to use this mode if there is a problem with automatic communication of
the EDID information from the attached display, and you want to ensure that the correct
information is stored on the inputs. Also, because this mode disables automatic EDID
reading and storage, you can retain one set of EDID information on the inputs and not
have it changed when another display is connected.
• Factory-loaded EDID files — You can select from a list of 48 EDID files that
are loaded on the switcher at the factory. Each EDID file contains a unique native
resolution and audio support (if applicable). The
the EDID files that are provided with the switcher.
• User-loaded EDID file — In addition to the 48 EDID files provided with the switcher,
four empty memory locations (50 through 53) are provided. To these slots you can
save the EDID of the display that is currently connected to the output port of the
switcher. Any of these four files can then be selected as one of the user-assigned
EDID files.
