Extron electronic MPS 409 manual EDID Minder, Input Group, Default EDID Resolutions

EDID Minder

The DVI and VGA/YUV groups feature EDID Minder, ensuring that each input source reads the EDID of the output display even when 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.

The DVI group does not support HDCP by default. In order to support HDCP, EDID Minder must be disabled. EDID Minder can be disabled for the DVI group using SIS commands.

Automatic Mode — If an output display has not been connected, a default EDID file is placed on the VGA and DVI inputs according to the following table:

Input Group	Default EDID
VGA	1024 x 768 @ 60 Hz
DVI	1024 x 768 @ 60 Hz

Figure 18. Default EDID Resolutions

When a display is connected to the group 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.

NOTE: When the HDMI/DVI combine mode is enabled at the same time EDID Minder

is enabled on the DVI inputs, the EDID will be updated with the HDMI output device EDID.
