ccc

Hi all,

I have a Ati 4850 X2 and back in the days when Windows 7 was in beta, I had this running with 4 monitors (Crossfire off). Now I have come to set this up again, with a RTM version of Windows 7 and the latest ATI drivers and it seems I can only have two monitors on at one time. If I try and set the monitors up in Control Panel, it simply disables the non-primary monitor, and if I attempt to do it in CCC, I get the message "To extend the desktop, a desktop or display must be disabled."

Does anyone know why this is and/or how to fix it?

I've currently tried using the latest ATI drivers and the drivers (i think) I was using over a year ago when I had this setup.

Thanks - James
