Edid Minder; Automatic Mode; User Assigned Edid Mode - Extron electronics MPS 602 User Manual

EDID Minder

The digital and analog groups feature EDID Minder, ensuring that each input source reads
the EDID of the output display even when the input is not selected. The result is the video
source powers up properly and reliably outputs content when selected. The EDID remains in
the selected mode (automatic or user assigned) even after loss of power.
Depending on the EDID mode selected, the EDID of the connected display is stored
automatically in slot 57 (RGB) and slot 58 (HDMI/DTP). Alternately, the user manually selects
an EDID file from an internal list. Whether stored automatically or manually, the EDID file is
written to an EEPROM for each input.

Automatic Mode

If an output display has never been connected, a default EDID file is placed on the RGB,
HDMI, and DTP inputs according to the following table:
When a display is connected to an output, the EDID of that display device is read and
replaces the default EDID on each input. The EDID remains even if the display is removed.
If a different display is connected or a user assigned EDID is selected, the previous EDID is
overwritten.

User Assigned EDID Mode

Using SIS commands (see
a table of EDID files. Six EDID file locations are reserved for user-loaded EDID files for the
RGB and HDMI DVI DTP inputs. Once a user assigned EDID is selected, it is stored at that
input and EDID polling ceases for a connected display. The following table lists the native
resolution of each factory EDID file.
