I'm curious if anyone else has seen this: I'm now running two video cards (and three monitors) on my Mac Pro: 1. 24" monitor on Geforce GT120 - in slot #2 2. 30" monitor on flashed XFX 4870 - dual link - in slot #1 3. 24" monitor on flashed XFX 4870 - single link - in slot #1 if the only monitor hooked up is the 30" (my primary) on the 4870 card, the machine boots up and I can hold down "option" to get my boot options (Mac, Windows via Bootcamp, CD, etc.) but if I have a monitor hooked up to the GT120 card, then *it* is the monitor that first comes up (well with the gray screen anyway) only holding down "option" seems to keep the machine from booting up, but I can not see the boot menu anywhere. When I do this, the monitor on the GT120 is all gray and the other two hooked up to the 4870 are in power-saving mode and don't even have a signal. (although if I leave the keyboard alone is does all boot up fine and then all three monitors have a signal) Any ideas anyone?
