Question

I want to know how to get automator or applescript to "detect displays" (which is found in Displays prefpane). Thanks.

Sorry I'm late, but this page was the only Google find on "script detect displays"
when I checked on June 26, 2011. The script commands worked immediately for
me and I offer V.K. belated thanks if he/she is still around for having solved this
longstanding problem for me. I had written a script earlier trying to do this, but it
didn't work reliably so I gave up on trying to use it.
If jockebq is by chance still around, I would recommend that he/she try doing as
I did and use a more simple version of the script, namely:
tell application "System Events" to tell the front menu bar of process "SystemUIServer"
  tell (first menu bar item whose value of attributes contains "displays")
    click
    tell 1st menu item of front menu
      click
    end tell
  end tell
end tell
I have this saved as a normal .scpt script and assigned to ctrl-opt-shift-d
in QuicKeys. It works every time.
