How many adapters does it take to hook a 24" ACD to an older Mac?

[bouncingsoul]

I got the 24" display for my older iMac with Mini DVI.

I thought Apple would have a Mini DisplayPort to Mini DVI adapter, but all they have are Mini DisplayPort to DVI, and DVI to Mini DVI.

If I chain both of those adapters will the 24" ACD work with my iMac?

Why isn't there is single adapter for Mini DisplayPort to Mini DVI? I thought Mini DVI was the most common port across the Mac line until the recent switch.

No your idea won't work. You'd need the mini-DVI to DVI adapter and something like this: http://estore.circuitassembly.com/products/DVI-to-Mini-Displayport-Adapter.html.

The reason that the Mini-DP to DVI adapter works is that DP is backwards compatible (electrically speaking) with DVI, while DVI (mini or otherwise) is not forwards-compatible with Display Port.

Adapters (more specifically, converters) like the one to which I linked are available, but they're all going to be pretty expensive ($100+).

Sorry.
