    I have an agp graphics Powermac G4 with a DVI and ADC Port. The ADC port does not supply the power i have been told but i have an Appl DVI to ADC adaptor Model A1006 That i connect to my machine and plug in cable and the USB works and the monitor powers on but there is no video. am I doing something wrong? Or is there no hope of getting this to work?

    I'm no expert on ADC, but have you tried a different set of cables?

    i.e. use a mains cable to power the monitor and an ADC-ADC cable to the monitor.

    Also, is the G4 known to be working, does it work with a different monitor?

    Same goes for the monitor, have you seen it working before?

    Can you clarify how you verified that the usb port in the monitor was working?

    I have tested my Sawtooth G4 with numerous Non ADC and also a DVI monitor. when i would press the power on the ADC monitor plugged in with the adaptor i would get a light slowly fade in and out i can plug a keyboard and mouse into the USB ports and have the lights light up and them be recongnized on my primary moniter.
    the monitor is working as i have tested it on a friends ADC enabled g4 and everything worked fine.

    Does your sawtooth have an ADC port on the video card? If so that should be enough to power it. Having said that if the video card has been swapped and thus why it has an ADC the ADC may not actually have power from the logic board.

    Sorry just checked and as I thought the sawtooth never had ADC so the video card has been swapped into the machine. The Video card you are using may not be compatable with the ADC - DVI adapter. You could try and borrow your friends video card and see if that makes a difference. Also the early cards (I don't know which you have) were not dual display compatable (they only drive one display, non spanning) try the display with the other disconnected. If it still doesn't work than I'd say either your
    ADC - DVI is faulty or not campatible iwth your video card. I say sell both separately and buy yourself a nice LCD. Plus you'll need a better/second video card to drive the second display along with the one you are using.
