Hi,
I have a friend who has a (about) 4 year old imac - its a 17" Intel 2.0GHZ model - sorry dont know the OS version.
Its got a problem that seems to have been pretty common where the main screen display is now just a bunch of stripes and completely unusable. I read up that this model has a mini-DVI port and that with the adapter (purchased today) it should be possible to plug in an external monitor and it should just use this external monitor as a mirror.
So - mini-DVI-> VGA dongle is plugged in -external monitor hooked up and turned on - hit the power button and after a minute of so up comes a pretty blue screen and once I moved the mouse around I could see the cursor. Doesnt seem to do anything when I click the mouse or hit the Mac button (probably not the right term - sorry mac people).
So its started using the external monitor as a extended desktop. My question is this - remembering that the main display is broken, how can I set the external monitor to be a mirror? Are there keyboard shortcuts?
Any help appreciated.
