hi! Thanks for taking the time to read this. When I boot my mac pro, which is connected to an apple cinema display (20", clear case, ADC to dvi adapter) I don't get a video signal. I have tried everything -- zapping the pram, pressing the motherboard reset switch and nothing works. I have connected the display and adapter to a PowerBook g4 with no problems, so I know that's not the issue.
Any help would be greaatly appreciated. Thanks.
