Your problem is getting the correct adapter ends for this trick.

You have to get the right male to female ratio or a gender bender to get all the connections together

Want to use old Apple ADC 22" Cinema Display as exterior display to new
MacBook Pro. Cannot find an adapter that's ADC to the miniport. Nor
even ADC to DVI and then DVI to port. Any ideas?
