Im trying to set up 3 displays on my Mac Pro running OSX 10.6.8 with a Radeon HD 5770 graphics card. There are 2 mini display ports, and a dvi connection. Im using a Cinema Display via mini display port, another Cinema Display via DVI port and a Sony LCD via HDMI/Mini display port adaptor. When all three displays are connected, the Cinema display connected through the the DVI port stays black. Is there any work around to this.

 

Thanks!!
