@eyoungren or others Since I got that rare FORMAC branded ADC to DVI adapter I always wanted it to use for my dual acrylic Cinema Display setup on my G4 MDD. My idea is to connect both monitors through 2x Apple DVI to ADC adapters I have so that the power supply from the G4 doesn't have to deliver the power and doesn't get so stressed and hopefully prolong it's lifespan. But I can't get to output any image through that FORMAC adapter. I only got once an image when I hotplugged the monitor while the system was running but got some nasty distortions on the screen and after replugging it in it didn't come back and I wasn't too keen to keep trying hotplugging. The adapter itself seems to work as I can get an output when I connect a HDMI monitor to the FORMAC one with just another DVI to HDMI adapter.
