View Full Version : Power Mac G4 Quicksilver, Dual ADC Monitors?

Sep 10, 2010, 02:02 PM
Just picked up a minty Power Mac G4 Quick Silver and two ADC Studio Displays. I'd like to hookup both displays, but I only see one ADC port.

What's my lease expensive dual ADC display option for this machine?

Thats going to be tough. I think the only way I'm aware of is to buy a graphics card that has both ADC and DVI outputs. Then get a DVI to ADC adapter and use that from the DVI port. Not exactly easy or cheap, but it would work.

I've never seen a graphics card with only one ADC port on. Are you sure there isn't a DVI or VGA port next to it too?

If there's a DVI, Hrududu's right, you need the an Apple ADC/DVI converter, last price retail was about 69 (UK). It's effectively a power supply, as ADC not only provides the video signal, but also power too. DVI is video signal only, hence the large brick that comes with the ADC/DVI converter.

There is a Formac version, but it's just as expensive if memory serves. Good luck!

Could I swap out for an ADC/DVI card and an adapter? What card should I look for?

See attached.
