Powering a 30″ Cinema Display with a Mini DisplayPort

First off, you need the mini DP to dual link DVI adapter, not the regular mini DP to DVI, to get a decent resolution on the Cinema Display. Second, you need the Macbook Pro EFI Firmware Update 2.2. Third, you guessed it, you need a MBP with a mini DP.

So all this sounds like a no-brainer, but here’s my story:

  1. I bought the latest MBP and a mini DP to DVI adapter and the resolution sucked.
  2. Found out I had to get the dual-link DVI adapter (I can still use the single-link with my 24″ monitor). I was very worried by all the trash being talked on the Apple store about this adapter being flaky and dying suddenly but I ended up getting it anyway. I need my 30″!
  3. Everything worked perfectly. Woot!
  4. Upgraded to Lion. Boom. Cinema Display Dead.
  5. Brought MBP and dual-link adapter to an Apple Store. The genius plugged it into their monitor in the back room and it worked “proved with a photo” so I was told to bring in my Cinema Display because it was likely a power issue. My old MBP (late 2008) could still power it so I had my doubts. Anyway, suckage… the CD was dead to me.
  6. Lots of bitching and moaning in public forums to no avail and jumping out the window seemed mighty tempting.
  7. MBP EFI Firmware update comes along and “includes fixes that resolve issues with Apple Thunderbolt Display compatibility”. Sounds close enough. Install. Bam. Cinema Display Alive.

Long story short, I spent way too much time on an issue that nobody would acknowledge or help with or even let me cry on their shoulder about. I was in deep trauma for months. And now it is over! If this post helps someone, I’ll have done my job here.

Hey, like this post? Why not share it with a buddy?
