    i usually use osx server (leopard) via remote desktop, but sometimes i need to use a monitor, but if i switch the monitor to another computer after a while the non connected osx server assumes no monitor is connected and when i switch the monitor back to it nothing happens? and the detect displays option is gone from system preferences because it doesnt think there is a display.

    any solutions would be good as logining out doesnt sort it so i have to reboot evrytime and its very very annoying.

    is there a command line detect display trick?

    What kind of Mac are you using as the server?

    We found that if you just unplug the VGA and then plug it back in, it won't recognize the monitor. But, if you pull out the DVI part as well, then you can plug that back in and it should see it.

    Maybe that will help.
