Can I use the displayport to dvi and then plug that in to my old DVI to ADC adaptor and plug in my old 23 & 17 inch display?

I just purchased a refurbish Mini 2.66ghz/2x2g/320/SD/AP/

?? Not sure the connections will fit.

Since the ADC is similar to DVI-I in that it can carry both analog and digital signals it should work.

The issue is going to be in the physical connections. The mini displayport to DVI adapter is DVI-D (digital) only. I have not seen, nor ever used ADC, but my best guess would be that the DVI to ADC adapter has a DVI-I connector which has 4 pins surrounding the long pin. Which means, the adapter you have, will have too many pins to fit into the DVI-D on the mdp to DVI as it does not have the openings for those 4 pins.

Take a physical look at your existing DVI adapter to verify. I have seen a DVI-D to DVI-I adapter, just don't have the time to go hunting for it at the moment. And it is only my best guess that it would work. You would end up with 3 adapters to get it working - mdp to DVI, DVI-D to DVI-I and the DVI to ADC.

(I have also moved this to it's own thread. It is not the same as the issue related to VGA connections.)

Is this the same issue as mine? I want to connect a new MacBookPro (with a mini-dvi port) to an older Apple Cinema Display (21") with an ADC female. I can't connect the two directly, so hoped an interim adapter would work. What more do I need to know before looking for the right ones?
Thanks.

No MBP has ever had a mini-DVI port. Beginning in Oct '08 the MBP has had a mini displayport (or mdp). Prior to that, they all had DVI.

Pretty much no matter which MBP you will need one of these - at $150 - $350.

If you have one of the newer MBPs, then you will also need a mdp to DVI adapter.
