Managing EDID video display information
Whenever a AV4PRO-VGA unit is powered on (or when the option is
selected from the configuration menu), it will interrogate the connected
monitor(s) to determine whether EDID (Extended Display Identification Data)
information is available. If EDID information is available, it will be copied and
used; otherwise a default set of data, stored within the AV4PRO-VGA, will be
substituted. You can also optionally choose to prevent the unit from seeking
new EDID information and instead rely only on stored data.
EDID Emulation
The AV4PRO-VGA units use our EDID Emulation feature to ensure that the
collected EDID information (up to two pages) is correctly supplied to every
connected computer, whether it is currently selected or not:

on to the connected computers. To revert to interrogating the video
display, use the F 2 function discussed above.
