Apr 15, 2012 6:47 PM in response to jim8by Grant Bennet-Alder,30" display requires a Dual-Link DVI. Is that the adapter they provided?
And it has active components, so you need to plug in the USB for power as well.

They gave me a miniport to single DVI connector... Curious why things worked so well on my
two earlier MBP's.

Apr 16, 2012 6:59 AM in response to jim8by Grant Bennet-Alder,★HelpfulA mini DisplayPort to single-Link DVI adapter will not work. The number of pixels on the screen (typical breakpoint is 1920 wide) is simply too high. Dual-Link has a second set of data leads to support the higher resolutions -- it has nothing to do with Dual Display.

What adapters were you using there?
Mini DVI to regular DVI would have no problems, as it is just wires and all the signals are present.

Apr 16, 2012 9:42 AM in response to Grant Bennet-Alderby jim8,★HelpfulMy now "backup" MBook Pro is a Model MacBookPro 4,1 (Intel Core 2 Duo).
The DVI port is built in to the right hand side of the machine. The one
previous (which still works) was similarly configured. Perhaps the issue
is that the new MBP has the higher resolution display option.
I guess I should have stayed with the 1440 x 900 pixel option rather than
the 1680 x 1050 option I got. That, however is a speculation which
has not been tested.

No, that is not the issue.
The issue is that the adapter from Mini DisplayPort to single-Link DVI is not the correct adapter for a screen wider that 1920 wide. Get the correct Dual-Link adapter and your beautiful 30" display will come alive once again.
I use a 30" cinema display with a Mac Pro, and would never go back for desktop work.
