How to force a Mac mini to recognize a LCD display.

thanks to Pixel44 for the info

Members of Atlantic.mac have found a way to force the Mac mini to recognize some "unsupported" LCD display. The solution: force the display detection procedure during the launch procedure.
Hereafter is the script:
------
tell application "System Preferences"
activate
set current pane to pane "com.apple.preference.displays"
tell application "System Events"
tell process "System Preferences"
tell button "Détecter les moniteurs" of group 1 of tab group 1 of front window to click
end tell
end tell
quit
end tell
-------------
NB : Do not forget to activate Universal Access in MacOSX preferences, "Activate access to helper peripherals".

For the lazy readers, we have compile the script, you simply need to add it to the launch on startup menu:
Force-LCD.sit
Otherwise, Apple has also published a solution on its Support webpages (thanks Daniel):
here. Basically it is based on a Power Management Unit (PMU) reset.
