Mac Mini + DVI Splitter

[Matthew Yohe]

I should've known this would probably cause problems...

So, I have a Mac Mini with an adapter plugged into it: A DVI-I to 2 other ports, DVI-D and, VGA. (Click here for a picture and specs)

The Mac Mini only will allow one signal (digital or analog) to be transmitted at a time. If I plug in the DVI plug from my Cinema Display, that turns on, if I plug in a VGA then the VGA monitor turns on but the Cinema Display turns off.

Is there any terminal hack or workaround that I can use to force the Mini to send out both analog and digital signals out its DVI-I port?

(Note: I know I cannot do spanned displays, I only want to mirror. This will be setup in a projector setting.)

I know that there are VGA splitters available, granted you would have to have 2 VGA signals, but there may even be DVI splitters too. Maybe try searching for powered splitters.

As far as I know i can only output one signial (either the analog or digital at a time).

My question is -- is there an easy way to make it switch between the two (rather than plugging in and unplugging/restarting)

Off one port, something like the DualHead2Go would be the way to go.

Alternatively, hook up an external USB video card.

Could you tell us what this does? I'd like to know before taking a chance on installing it. Thanks!
