I recently found an older 20" Cinema Display at a yard sale. It was super cheap, and they said it worked great, so I took their word for it.


It has a bundled cable deal that seems permanently attached to the back of the monitor, has some sort of power brick midline, and then has a DVI, USB and Firewire connection. I bought a Mini DisplayPort to DVI adapter off Amazon.


Problem is, all I'm getting is a black screen on the monitor. The LED on the monitor comes on, but nothing on the screen. The laptop does seem to be finding the monitor, and it even seems like it's "there" in that I can drag windows completely off my laptop screen...but still, nothing but black on the display.


So, is it a bum monitor? Or am I doing something wrong? Any way to make this work?

    I see all these people swearing that that monitor works with that adapter, but it never has for me. Not on my 2011 17" MacBook Pro, or on a couple other newer MacBook's I tried. One of them saw it briefly, and then never again. My Macbook Pro has never even seen the monitor. Yet the same monitor works just fine on my older MacBook with a DVI connector. I do have a DisplayPort to VGA adapter, and another VGA->DVI connector. When I hook that up, the Mac sees the monitor, I can change the settings--but the screen stays blank.

    A Mini DisplayPort to DVI adapter should work if plugged in all the way (no metal showing).


    VGA adapters won't work since the display needs digital video signals.

    Well, I guess in theory it should work, but it definitely isn't working for me..
