I have an older (2005) 23-inch Apple Cinema Display that works with an even older Mac G4 (from 1999) via an adapter made by Dr. Bott. For your reference, here's the link for the specs on the display and Dr. Bott adapter.

I connected the Cinema Display to the Dr. Bott adapter to an Apple mini display port to DVI adapter to my 2009 Mac Book Pro and it doesn't recognize the older display.
This may be a silly question but are there any other adpaters I can use or do I just need to use a newer monitor? Any suggestions on Apple friendly monitors that work well with a MacBook Pro (2009) and a mini-display / HDMI adapter?
