I have recently bought the radeon 7870, which comes with 1 DVI, 2 Mini DP and 1 HDMI port.
My monitors are two VGA, one has a DVI cable which is my main monitor.
The other one has the original VGA cable going through a VGA>DVI adapter.
In my old setup I had 2 DVI ports and that worked, so I bought a XFX Active DVI>Mini DP Adapter and plugged it in.
CCC recognizes the other display, but my monitor doesn't appear to get any signal it's on standby and displays nothing.
I tried putting the active adapter straight on the DVI cabled monitor and then put on the cable with the VGA>DVI adapter.
Nothing seems to work even though extended desktop mode is on, I can see it on my CCC under displays.
The Mini displayport extended monitor just doesn't extend or duplicate at all.
Please help.
