View Full Version : USB ports on back of LCD don't work

i have a Apple Studio Monitor 17 in M7649 with 2 ea. usb ports on the back. How do i get them to work??? My M7649 LCD connects to my Mac G4 with what I believe is called DVI connection. In the past I have used a DVI-ADC adapter #A1006 EMC # 1918. This is the adapter with a USB line that connectors into the Mac's usb connector along with the DVI monitor connection and gives usb access to the USB ports built into the back of the LCD. I no not where this adapter ran off too (DVI-ADC adapter #A1006 EMC # 1918) is there any other way to get USB access from the Mac (G4) to the LCD????!!!!

Your monitor has an ADC (Apple Display Connection) (http://upload.wikimedia.org/wikipedia/commons/thumb/0/09/AppleDisplayConnector.jpg/800px-AppleDisplayConnector.jpg) plug on it which runs power, USB and video to the LCD without any other plugs required.

Now depending on your G4 mac, from the G4 Gigabit Ethernet model up to the G4 MDD, you will need a video card that has that type of female plug on it.

Best bet would be getting a video card from the mac that has an ADC port on it.

Here is a list of video cards that Apple has made a list of for the G3 and G4 towers. (http://docs.info.apple.com/article.html?artnum=42957)
