You might take a look at this : "http://macperformanceguide.com/blog/2010/20100916_MacProVideo--macpro-bugs.htm l".
I have very similar problems with an equal machine and also a DELL monitor also with DVI, just that the screen goes black BEFORE the login screen appears and not after. I prefer to login blindly and then move the mouse cursor blindly to a screen corner as described in the link above.
If you have a chance to tell Apple, please do it!
BTW: doubleyouseven works fine...
Hey thanks for your comment. So i'm not the only one with that problem.
The hot corner workaround may work but i don't use hot corners because it would disturb me on regular work.
Apple has to fix that. Especially if it is true for Apple Displays as well, as they said on the website.
What is meant by "doubleyouseven"?
Wow! I have a similar issue, started out with a 24" Dell monitor herringbone & flashing on and off at start up. I thought it was the monitor since it happened once in awhile, so I purchased a new 27" Samsung monitor everything seemed ok until tonight, black screen as described above. Now I know am not alone. My video card is the ATI HD 5770.
What also might be interesting:
If you start doubleyouseven, everything works fine. It's a great system.
If you then directly reboot to MacOS without switching the computer off, you get a horrible screen with terrible noise that is so ugly you think your monitor will soon explode. Note that you get that terrible picture AFTER the boot screen (which is fine), you get it during login.
When you manage to shutdown the Mac and switch it completely off, then reboot to MacOS, everything is (hopefully) fine again.
This proves that Apple's graphics card initialisation in MacOS is insufficient.
