I INSTALLED YOSEMITE 10.10.3 USING CLOVER ON MY DELL OPTIPLEX 980.

Both display cards work individually when only one is plugged in. Both cards are detected by the system report. Radeon 7470 & Radeon 4550. Additionally I have a Diamond usb to dvi which the system also detects but I am given no options for a second monitor.

Any help would be appreciated.

How did you even get it to install? I cant even install Snow Leopard correctly

I INSTALLED YOSEMITE 10.10.3 USING CLOVER ON MY DELL OPTIPLEX 980.

Both display cards work individually when only one is plugged in. Both cards are detected by the system report. Radeon 7470 & Radeon 4550. Additionally I have a Diamond usb to dvi which the system also detects but I am given no options for a second monitor.

Any help would be appreciated.
