new to the board - excuse any ignorance! i just purchased a new powerbook last week and wanted to use dual displays with my 17" adc flat crt monitor (the one that has the graphite translucent back - looks like an emac). i purchased the dvi to adc adapter at my apple store because they told me it would work. after hooking it up, i am still getting no picture on my crt monitor. my powerbook detected the display, and the display itself will shut down my powerbook via the power button on the display. i bought this display used for $150, because i thought from a cost standpoint, it was a lot cheaper than shelling out several hundred on an lcd for more desktop space. is there something i need to do to get the monitor functioning? ....or is there a compatability problem? any help appreciated!!! thanks!!!
