Hi everybody. I just got into possession of a 17 inch Studio Display, the CRT one with the ADC connection (Translucent back) and am hooking it up to my dual 1.8 G5 powermac. I plug it in and the picture is good and everything, but I can't access the onscreen controls. So I can't seem to mess with the screen geometry; I only get Display and Color tabs. I tried 'Detect Displays' and it knows its a Apple Studio Display, but it doesn't add any options. Pressing the displays button to access the controls does nothing, but the power button will turn the mac on and put it to sleep. Also, the USB ports on it don't work, but i'm not entirely worried about those. It didn't come with a Cd or anything, so I don't know If I'm missing something. I am up-to-date on updates. Any help on how to get those controls would be much appreciated.
