[quote The Grim Ninja] ... If I buy an ADC to DVI adapter, can I use a DVI to VGA adapter with it? ... The main question is, is it common practice for the ADC->DVI adapters to include the analog signal lines, or might they simply skip those? ...
Short answer: Don't think it'll work, certainly not with the Belkin adapter..
Long answer:
I too just picked up the Belkin adapter (look for my thread here a few days ago.)
The standard Apple DVI-to-VGA adapter supplied with G5s etc. won't connect to it, sorry guys --- I wanted to also hook my CRT up to the ADC port on my Mac.
According to http://www.pacificcable.com/DVI_Tutorial.htm, the DVI end of the Belkin is a DVI-D Female Dual-Link, whereas the DVI end of the standard Apple DVI-to-VGA adapter is a DVI-I Male Single-Link --- if you look closely, you'll see that a DVI-I Male Single-Link connector has 4 extra pins on one end with nowhere to go into a DVI-D Female Dual-Link.
(Don't anyone get confused on the single-link vs, dual-link here; it's not referring to analog or digital or digital+analog.)
The other issue is that because the Belkin adapter is a "DVI-D" cable, it doesn't pass an analog signal. It would need to be "DVI-I" to also include an analog signal.
I'm assuming the ADC port has available an analog signal --- 17" Studio Displays w/ ADC were of course CRTs, if that means anything. Anyone know of another ADC-DVI adapter besides the Belkin? (Apple's $99 adapter is a DVI-ADC, not ADC-DVI, so I'm guessing the genders are wrong for here?)
This thing will take a DVi port and give you VGA, for a price: http://www.pacificcable.com/Picture_Page...ame=DC-DA1 ($350!)
