Q: 24" LED Cinema Display not working with Mac Pro

I have a Mac Pro (2 x 2.4 GHz Quad-Core, model identifier MacPro5,1) purchased in late 2010 and a 24" LED Cinema Display. The Mac Pro has three video ports--a full-sized DVI and two mini DVI. When I plug the Cinema Display into either of the mini DVI ports, I cannot get a picture, although the iSight camera works fine. If I plug another monitor into the full-sized DVI port the computer believes that is the only monitor. The Cinema Display works fine with my MacBook, so there is nothing physically wrong with it.

Is it not possible to use this monitor with a Mac Pro without an adapter, even though the Mac Pro does have mini DVI ports?

Mac Pro, Mac OS X (10.6.6)

    Sorry, that should have been "Mini DisplayPort", not "mini DVI" above.

    Is the Mini DisplayPort plug pushed all the way in? It may take more force than expected.

    Malcolm Rayfield hit it on the head! I had thought it couldn't be a plugging-in problem because the camera still worked, but it must have been doing that through the USB connection. I had plugged and unplugged this thing several times, too--I guess I was just being too gentle with it.

    i just wanted to add folks that sometimes on the older models from 2008 the USB cable must be connected so the embeded camera would work -- cheers
