I have a G5 and a G4 emac that I would like to add a second monitor to each of them. Remarkably, searching under extended desktop or dual monitors have gotten me a whole lof of nothing. With the G5 I gather I just need to hook up a 2nd monitor to the back of the machine, but then what? Go to Displays in the System Prefs? And for the emac, should I use a VGA adapter to link the emac and 2nd monitor together? Thanks for any help you can give me.
