Apple DVI to ADC Adapter - DID NOT WORK !!!!

Question

I have a PowerMac G4 Model M5183 and I wanted to connect it to a 20" Apple Cinema Display that I got.
Because the display output on the computer is different than the monitor, I bought the Apple DVI to ADC Adapter that everyone talks about on the support pages.
Problem is, that the start button on the monitor, will not start the computer. And if I start the computer with the ON/OFF button on it, the monitor comes on after a few seconds, the "Apple" appears and the wheel starts spinning....but the monitor goes black after about 25 seconds. I hooked comp. to a Viewsonic via the DVI port and the computer works fine. I hooked the monitor to a G4 with the ADC port and the monitor works fine. AND, I took the first Apple DVI to ADC Adapter back to the store, thinking it was bad...second one didn't change anything.
HELP!!!!!

Answer 1

Computer will not start with button on display.
When you use the power button on the display, the start signal is transmitted via the USB bus to the computer. The DVI interface on the computer does not have the required USB signals to start the computer. If that is a requirement, you need a graphics card with ADC connector, which requires a computer with the 25 Volt power supply.
... the monitor goes black after about 25 seconds.
That is about the time the System uses the stored Display Preference to re-initialize the display. It may mean the stored Display Resolution Preference has the wrong values for this display to sync up. You can start up from another source and attempt to delete the preference file, or start up using another monitor and set the screen resolution to something really simple, like 640 by 480.
Your Mac cannot query the display about its capabilities, because its usual method, across the built-in USB connection, is not available. So it must use the stored value instead.
