I've been working on setting up a MacPro at work (I set up faculty members' computers at the university I attend), and I've gotten most of the many holes ironed out at this point. It's set up to run both OSX and Vista 64 through Boot Camp. I'm using the NTFS-3g driver so that the Windows drive is writeable from the Mac side. This required me to use rEFIt, which provides a boot menu at startup so that I can select which partition to run (NTFS-3g partitions aren't recognized by the Mac at startup, so this is the workaround).
So here's the issue... David (the faculty member) has a three monitor setup, with two 24" Samsung SyncMaster 215T's set in portrait on the left and right, and a huge 30" Dell 3008WFP in the middle in landscape (all are using DVI-D). The Dell is of course set as the primary display. When the computer boots up, rather than showing the off-white Apple boot screen, or -- as I would hope -- the rEFIt boot menu, it's just a black screen. The monitor recognizes the input because the status light turns from amber to blue. Once it gets into an OS all three monitors the OS appropriately.
This is an issue since David needs to be able to select an OS when he boots up, otherwise it will always go with the default.
I hooked in just one of the Samsungs via VGA, and the boot menu appears just as one would expect.
So the culprit is obviously the Dell. I went to their website and installed the driver for it (although now that I think of it, I may have only installed it on the Vista side... I wonder?). I've tried shutting it off and then on. I know the connections are secure and the cables are good. I've tried flipping through the monitor's different inputs during boot up as well. I'm not really sure what else can be done.
