Why is Cinema 30" full resolution not supported any more?

  1. Connect external Apple Cinema 30" to MacBook
  2. Go to Displays, and try to set resolution on the Cinema to its maximum
  3. Can't do it. Instead of offering me all resolutions up to 2560x1600, it only goes up to 1280x800

None of these work:

  • I make the external monitor the main display (menu and dock-bearing) or not
  • I ask the Mac to "detect displays"
  • I try with a different miniDV to DVI adapter
  • I go into dual-display or single-display mode
  • I try many possible relative positions for both displays

The MBP is a 15", 2.66 Gz Core 2 Duo, 4GB, with OS X 10.6.3

IThanks, Lemerise, that doesn't work because it refers to older models than mine (2008 I should have clarified that I had already read it...

Also, I should clarify that I have reset the PRAM without success. I am still stuck, throw anything you've got to it, I will appreciate it greatly! :)


Actually, Lemerise, you were absolutely correct. It turns out that after THREE trips to the Apple Store "geniuses", and two more to an Apple Certified Repair, after a collective of more than 6 people telling me that "There is no other connection possible between your MBP and a Cinema 30", that dinky connector we just sold you for $29 is the ONLY one there is", after all of that... I finally discover that there IS another connector, specially for the Cinema 30" monitor. the "mini DisplayPort to Dual-Link DVI Adapter", part Number MB571Z/A, which solves the problem. Just as it said in the article you pointed me to.

You will still feel raped when the Apple Store guy tells you that a crappy piece of cable and plastic costs... $99 (you can buy another monitor for that), but that is just "Job's ambition to be Bill Gates" at work. Thanks a LOT!
